Abstract (sommario):

Age is a key factor in plantar pressure distributions during the development of obese children. However, the existing evidence for age-related plantar pressures of obese children is not sufficient to make clear how the plantar pressures would change with the increasing age. This study aimed to evaluate the plantar pressure redistributions of obese children after a three-year follow-up and to further compare these changes with normal-weighted children. Ten obese children and eleven normal-weighted counterparts were involved in this study. Plantar pressure measurements were undertaken using a Footscan® plantar pressure plate on two test sessions three years apart. Peak pressure, pressure-time integral, standard maximum force, and z-scores of these variables were analyzed. Loading transference analyses were applied to detect the different loading transferring mechanisms between obese and normal-weighted children. Significantly increased plantar pressures were observed at the lateral forefoot and midfoot for obese children, which gradually deviated from those of normal-weighted children over the 3 years. With the increasing age, obese children displayed a lateral loading shift at the forefoot in contrast to the normal-weighted. Early interventions are cautiously recommended for obese children before the plantar loading deviation gets worse as they grow older.

Abstract (sommario):

Background: Elevated dynamic plantar pressures are a consistent finding in diabetic patients with peripheral neuropathy, with implications for plantar foot ulceration. This study aimed to investigate whether a first-ray amputation affects plantar pressures and plantar pressure distribution patterns in individuals living with diabetes and peripheral neuropathy. Methods: A nonexperimental matched-subject design was conducted. Twenty patients living with diabetes and peripheral neuropathy were recruited. Group 1 (n = 10) had a first-ray amputation and group 2 (n = 10) had an intact foot with no history of ulceration. Plantar foot pressures and pressure-time integrals were measured under the second to fourth metatarsophalangeal joints, fifth metatarsophalangeal joint, and heel using a pressure platform. Results: Peak plantar pressures under the second to fourth metatarsophalangeal joints were significantly higher in participants with a first-ray amputation (P = .008). However, differences under the fifth metatarsophalangeal joint (P = .734) and heel (P = .273) were nonsignificant. Pressure-time integrals were significantly higher under the second to fourth metatarsophalangeal joints in participants with a first-ray amputation (P = .016) and in the heel in the control group (P = .046). Conclusions: Plantar pressures and pressure-time integrals seem to be significantly higher in patients with diabetic peripheral neuropathy and a first-ray amputation compared with those with diabetic neuropathy and an intact foot. Routine plantar pressure screening, orthotic prescription, and education should be recommended in patients with a first-ray amputation.

Abstract (sommario):

Background: We investigated the effectiveness and durability of two types of plantar padding, the plantar metatarsal pad and the single wing plantar cover, which are commonly used for reducing forefoot plantar pressures. Methods: Mean peak plantar pressure and impulse at the hallux and at the first, second, third, and fourth metatarsophalangeal joints across both feet were recorded using the two-step method in 18 individuals with normal asymptomatic feet. Plantar paddings were retained for 5 days, and their durability and effectiveness were assessed by repeating the foot plantar measurement at baseline and after 3 and 5 days. Results: The single wing plantar cover devised from 5-mm felt adhesive padding was effective and durable in reducing peak plantar pressure and impulse at the first metatarsophalangeal joint (P = .001 and P = .015, respectively); however, it was not found to be effective in reducing peak plantar pressure and impulse at the hallux (P = .782 and P = .845, respectively). The plantar metatarsal pad was not effective in reducing plantar forefoot pressure and impulse at the second, third, and fourth metatarsophalangeal joints (P = .310 and P = .174, respectively). Conclusions: These results imply limited applicability of the single wing plantar cover and the plantar metatarsal pad in reducing hallux pressure and second through fourth metatarsophalangeal joint pressure, respectively. However, the single wing plantar cover remained durable for the 5 days of the trial and was effective in reducing the peak plantar pressure and impulse underneath the first metatarsophalangeal joint.

Abstract (sommario):

We test the premise that peak plantar pressure is located directly under the bony prominences in the forefoot region. The right foot of standing volunteers was examined in three different postures by a CT-scanner. The plantar pressure distribution was simultaneously recorded. The position of the metatarsal heads and the sesamoids could be related to the corresponding local peak plantar pressures. The metatarsal heads 1, 4, and 5 had a significantly different position than the local peak plantar pressures. The average difference in distance between the position of the metatarsal heads and the peak plantar pressure showed a significant correlation: on the medial side the head was located more distally to the local peak plantar pressure, on the lateral side more proximally. The findings suggest that normal plantar soft tissue is able to deflect a load. The observations might improve insight into the function of the normal forefoot and might direct further research on the pathological forefoot and on the design of footwear.

Abstract (sommario):

Foot planter pressure is the area that is between the foot and the surface during daily life activities and other activities. It can help to solve the problems of such disease like gait, diabetes and foot ulceration. It also plays the main role in the patients who are at the risk of variety of foot problems. This paper is about to know the brief discussion on foot related problems. In this article we also discuss the types of foot planter pressure measurement and its future technology. Foot planter system is the system which is very helpful to the patients of foot problems. This system is not only for the patients of foot problems but also used in sports and our daily life. Future applications of the planter pressure to improve in design and more comfortable. High plantar pressures have been shown to be a key risk factor for foot ulceration in people with diabetes. Patients are generally prescribed insoles designed to reduce pressure. New technologies like plantar pressure measurement devices and 3D foot scanners have the potential to improve insole design. Still, it is not clear to what such technologies are currently using by physicians. After that, there has been previous research designed to understand how best to use technology to improve insole design for patients with diabetes.

Abstract (sommario):

The aim of this study was to evaluate whether high plantar foot pressures can be predicted from measurements of plantar soft-tissue thickness in the forefoot of diabetic patients with neuropathy. A total of 157 diabetic patients with neuropathy and at least one palpable foot pulse but without a history of foot ulceration were invited to participate in the study. Plantar tissue thickness was measured bilaterally at each metatarsal head, with patients standing on the same standardized platform. Plantar pressures were measured during barefoot walking using the optical pedobarograph. Receiver operating characteristic analysis was used to determine the plantar tissue thickness predictive of elevated peak plantar pressure. Tissue thickness cutoff values of 11.05, 7.85, 6.65, 6.55, and 5.05 mm for metatarsal heads 1 through 5, respectively, predict plantar pressure at each respective site greater than 700 kPa, with sensitivity between 73% and 97% and specificity between 52% and 84%. When tissue thickness was used to predict pressure greater than 1,000 kPa, similar results were observed, indicating that high pressure at different levels could be predicted from similar tissue thickness cutoff values. The results of the study indicate that high plantar pressure can be predicted from plantar tissue thickness with high sensitivity and specificity. (J Am Podiatr Med Assoc 94(1): 39-42, 2004)

Abstract (sommario):

Plantar pressure sore occurrence is an indicator of increased plantar pressures which may develop into subsequent foot problems and pain. Therefore, the aim of this study was to assess the effect of special footwear on plantar pressure sore distribution. 67 healthy pregnant women participated at all data collection session at their 27, 32 and 37 gestational weeks. At each data collection session, the plantar pressure sore distribution was assessed for both feet. During the first data collection session participants were randomly divided into a control and experimental group. Experimental group obtained the special footwear. For the control group, the results show an increased in pressure sores occurrence in the medial edge of thumb and first metatarso-phalangeal joint. The special footwear introduction in the experimental group increased the pressure sore occurrence at the edge of the heel, probably associated with the plantar pressure redistribution more to the heel area. The distribution of pressure sore areas of the control and experimental group is in accordance with our hypothesis that the special footwear redistributes the plantar pressures, however, the trend of these changes is not clear as there are many factors influencing the foot condition during advanced stages of pregnancy.

Abstract (sommario):

We sought to investigate the magnitude and duration of peak forefoot plantar pressures in rheumatoid arthritis. The spatial and temporal characteristics of forefoot plantar pressures were measured in 25 patients with a positive diagnosis of rheumatoid arthritis of 5 to 10 years’ duration (mean, 8 years) and a comparison group using a platform-based pressure-measurement system. There were no significant differences between groups in the magnitude of peak plantar pressure in the forefoot region. Significant differences were, however, noted for temporal aspects of foot-pressure measurement. The duration of loading over sensors detecting peak plantar pressure was significantly longer in the rheumatoid arthritis group. In addition, the rheumatoid arthritis group demonstrated significantly greater force–time integrals. Significant increases in the temporal parameters of plantar pressure distribution, rather than those of amplitude, may be characteristic of the rheumatoid foot.

Abstract (sommario):

A new, high resolution, pressure-sensitive insole was tested and found to provide reproducible measurements of static and dynamic plantar pressures inside the shoe of normal test subjects under certain conditions. However, calibration between separate sensors was poor and the sensor pads showed significant wear with use. This system was also used to investigate the effect of heel wedges on plantar foot pressure to determine whether this system was sensitive enough to detect the effect of a gross shoe modification on plantar foot pressure. Medial heel wedges decreased plantar pressures under the first and second metatarsals as well as under the first toe, and shifted the center of force laterally in all portions of the foot. Lateral heel wedges decreased pressures under the third, fourth, and fifth metatarsals, increased pressures under the first and second metatarsals, and shifted the center of force medially in all portions of the foot. Our evaluations indicate that it is possible to measure static and dynamic plantar foot pressures within shoes and to study the possible effect of shoe modifications on plantar pressures in controlled gait trials.

Abstract (sommario):

Introduction This study focuses on the plantar pressure distribution patterns in children aged 4 to 7 years of age for the purposes of a better understanding of any age-related changes and from that a better understanding of age-related changes in foot function and structure. Method Ninety-eight children who achieved the correct age-related height, weight and locomotion skills; were born within a normal gestational period and had no gait abnormalities underwent plantar pressure analysis. Peak plantar pressure and plantar pressure time integral data were obtained from the: calcaneus, medial and lateral midfoot, each of the five metatarsal heads and hallux. Both longitudinal and crosssectional data were collected at 4, 5, 6 and 7 years of age. The data subsets were analysed to determine if there were any age-related changes. Results Prior plantar pressure data analysis found no significant difference between the left and right feet (p>0.05), no significant difference between males and females (p>0.05) and some evidence of a weak, positive correlation between plantar pressure data and body weight (r<0.5). There was no systematic change across the longitudinal and crosssectional plantar pressure data for the 4, 5 and 6 years olds. There were significant differences in the plantar pressure data between 4 and 7 years of age (p<0.05). Conclusion The two year interval between 4 and 6 years of age is too short a time period to observe systematic change in plantar pressures. Annual age increments are not a key marker for changes in plantar pressure between these ages. Changes between 4 and 7 years of age suggest that this window of time may be large enough to observe differences in plantar pressure. Xlll

Abstract (sommario):

This thesis is concerned with the design and building of a foot pressure system capable of measuring the pressure distribution underneath the diabetic foot. The system is developed to have a higher resolution and be more cost-effective than existing commercial systems. The biomechanics of the foot and ankle is explained in detail, providing an explanation for the relationship between high pressures and ulcerations. Various techniques of measuring foot pressure are reviewed, providing a thorough understanding of the advantages and disadvantages of each technique. The system developed uses the technique of interferometry, which is discussed in detail, explaining why the Fizeau Interferometer technique was chosen over other interferometer techniques. A number of materials were tested as to their suitability to be used as the pressure plate in the system i.e. compression/force relationship. From the results 'Perspex' was found to be the most suitable material. Two fringe-processing software packages were tested i.e. Fringe Processor 2 and Fringe Pattern Analysis (FRAN), with Fringe Processor 2 being chosen for this research. A graphical user interface for image display was created in order to display and analyse the various pressure images. Three prototypes were implemented. The first used a variation on the Fizeau interferometer, the second used a variation on the Twyman Green interferometer, whilst the third improved on the use of the variation of the Fizeau interferometer. By analysing the advantages and disadvantages of each prototype, the 3 rd prototype was chosen as the most suitable for achieving the aims and objectives of this research. This prototype was subjected to various tests i.e. resolution, measurable area, repeatability, calibration, short term reliability and sensitivity to heat. Various normal and pathological foot measurements were taken and analysed, and the effectiveness of the image display graphical user interface tested. The main contribution of this thesis is the use of interferometry to measure pressure. This in turn provides a foot pressure system, which has extremely high resolution and accuracy. The simple nature of the new pressure system also means that the entire system is very cost effective.

Abstract (sommario):

Patients affected by Diabetes Mellitus have reduced tactile sensitivity and atrophy of the small muscles in the foot, resulting in high-pressure points that may remain unnoticed. The increased pressure can cause micro-trauma leading to wounds. Because of the Diabetes Mellitus, DFUs do not heal easily. Up to 25% of them will develop diabetic foot ulcers (DFU), and 25% of DFUs that do not heal ultimately result in amputation. This Master Thesis will describe and gather results of a newly acquired large international collaborative EU project (EIT Health 2020-2022) between three universities and three companies across Europe. This collaborative group will be the first to tackle the Diabetic Foot Ulcers problem preventatively with an innovative shoe concept, with seven different apex settings, which can be easily modified to avoid ulcerations in different areas of the foot. As an initial pilot, this master thesis project focuses on the analysis of the plantar pressure distribution by using the innovative shoes DR Comfort based on the adjustable rocker profiles, used as a prototype for the prevention of the Diabetic Foot Ulcer (DFU) formation in patients affected by Diabetes. This project captures the motion data of healthy people with different shoe soles while walking at different levels of speed and assess the values of the peak plantar pressure, with the use of the Pedar-X, a measuring system device for the in-shoe plantar pressure. The evaluation of the adjustable rocker profiles is made through the calculation and analysis of the significant differences and p-values in peak plantar pressure, as well as the analysis of the Mean Plantar Pressure (MMP). The results of this study show a reduction (although not pronounced) of the areas that are more affected by DFU. This study cannot be generalized to diabetic patients since ethical approval has not yet been received.
Patienter med DM har minskad taktil känslighet och atrofi i de små musklerna i foten, vilket resulterar i högatryckpunkter som kan för bli obemärkta. Det ökade trycket kan orsaka mikrotrauma som leder till sår. På grund av Diabetes Mellitus, läker inte DFU lätt. Upp till 25% av dem kommer att utveckla diabetiska fotsår (DFU), och 25% av DFU: er som inte läker leder slutligen till amputation. Detta examensarbete kommer att beskriva och samla resultat från ett nyförvärvat stort internationellt EU-projekt (EIT Health 2020-2022) mellan tre universitet och tre företag i hela Europa. Denna samarbetsgrupp kommer att vara den första att förebygga problemet med diabetiska fotsår med ett innovativt skokoncept diabetiska fotsår med ett innovativt skokoncept. De kommer utföras med sju olika inställningar som lätt kan modifieras för att undvika sår på olika områden i foten. Som en första pilot fokuserar detta examensarbete på analys av plantartryckfördelning genom att använda de innovativa DR Comfort-skorna baserade på de justerbara ”rocker”-profilerna, som används som en prototyp för att förebygga bildningen av Diabetic Foot Ulcer (DFU) hos patienter som drabbats av Diabetes. Den här avhandlingen fångar rörelsen hos friska personer med olika skosulor medan de går i olika hastighet och analyserar värdena för det maximala plantartrycket med användning av pedar-x. Pedar-x är en mätanordning för plantorns tryck i skon. Utvärderingen av de justerbara ”rocker”-profilerna gjordes genom beräkning och analys av de signifikanta skillnaderna i top plantartrycket samt analysen av plantartryckets maximala medelvärde (MMP). Resultaten av denna studie visar en minskning (även om den inte betydlig) av de områden som mest drabbats av DFU. Denna studie kan inte generaliseras till diabetespatienter eftersom etiskt godkännande ännu saknas.

Objetivo: Comparar a pressão plantar e a velocidade do deslocamento do centro de pressão (CdP) entre pés normais, cavos e planos em indivíduos adultos saudáveis. Metodologia: foi realizado um estudo observacional, com 26 indivíduos saudáveis, classificados com pés normais (n=22), pés cavos (n=6) e pés planos (n=24) baseado no Foot Posture Index – 6. Os indivíduos caminharam normalmente ao longo de um espaço de 10 metros, enquanto usavam um sistema de análise de pressão plantar F-scan (Tekscan). Utilizaram-se 5 áreas que incluíram o retropé, médiopé, antepé, dedos e pé total. A pressão plantar máxima (PPmáx) e o integral pressão-tempo (IPT) e o centro de pressão (CdP) foram calculados para cada área. Resultados: não foram encontradas alterações significativas (p> 0,05) entre as variáveis PPmáx e o IPT com o arco plantar, no entanto foram encontradas alterações significativas para a velocidade do CdP com o arco plantar (p <0,05). Conclusão: este estudo confirma que o arco plantar longitudinal medial influencia algumas variáveis de pressão plantar, nomeadamente a velocidade do CdP.
Objective: To compare plantar pressure and the velocity of center of pressure (COP) displacement between normal, cavus and planus foot in healthy adult subjects. Methods: An observational study was performed with 26 healthy individuals classified as normal feet (n = 22), cavus feet (n = 6) and planus feet (n = 24) based in the Foot Posture Index - 6. Individuals walked normally over a 10 meters span, while using an F- scan (Tekscan) plantar pressure analysis system. Five areas were used that included the hindfoot, midfoot, forefoot, toes and total foot. The peak pressure (PP), integral pressure-time (PTI), center of pressure (COP) were calculated for each area. Results: no significant changes (p> 0.05) were found between the variables peak pressure (PP), total pressure-time integral (PTI) with the plantar arch, but significant changes were found for the velocity of center of pressure (COP) with the plantar arch (p <0.05). Conclusion: this study confirms that the medial longitudinal plantar arch influences some plantar pressure variables, namely the velocity of COP.

Abstract (sommario):

Most activities of daily living and numerous modes of physical activity incorporate some form of ambulation, of which the foot and ankle constitute the first link in the kinetic chain. A change in foot or ankle structure may therefore have subsequent effects on the superincumbent joints of the human body such as the knee, hip and lower back. Plantar pressure and impulse measurements can therefore provide greater insight into the mechanics of the foot under load-bearing conditions with regards to the areas and regions of the foot that exhibit the largest pressure values and impulse figures. Hence, it is of importance to establish normative data so as to obtain a frame of reference to identify those individuals that fall outside these norms and may exhibit a larger probability of injury. Aim and Objectives: The primary aim was to identify and compare the plantar pressure distribution patterns and impulse values of students of a South African university of different gender and race groups. To realise this aim two specific objectives were set. The first was to determine whether height, weight, body mass index (BMI), gender, race, and the level of physical activity were related to the pressure and impulse values obtained, and the second was to generate reference tables from the normative data gathered. Method: The RS Footscan system was used to measure the pressure and impulse values of the foot. The characteristics that were analysed were height, weight, body mass index and the level of physical activity of the participant and their respective association with plantar pressure and impulse values obtained. This information was then used to establish normative data. A quasi-experimental study design utilising convenience sampling was implemented as the intention was to investigate as single instance in as natural a manner as possible. Convenience sampling was used with predefined inclusion and exclusion criteria. A total of 180 participants were utilised in this study and were subdivided as follows: Gender: Males (n = 90); Females (n = 90); Race: African black (n = 60); white (n = 60) and coloured (n = 60). Each race group therefore comprised of 30 males and 30 females respectively. The anthropometric profile of participants was as follows: Age (S.D.) = 22.21 (S.D. ± 2.93) years; Height (S.D.) = 169.69 (S.D. ± 8.91) cm; Weight (S.D.) = 66.97 (S.D. ± 12.01) kg; BMI (S.D.) = 23.16 (S.D. ± 3.15) kg/m2. Participants were asked to complete a questionnaire prior to testing that would identify all exclusion criteria consisting of: the presence of foot pain or deformity, acute lower extremity trauma, lower extremity surgery, exhibited problems of performance including eye, ear or cognitive impairment, diabetes mellitus or other neurological neuropathy, or the use of walking aids. Anthropometric measurements were then taken for those participants that qualified for the study. Participants were required to perform approximately five warm-up trials to familiarise themselves with the testing equipment before testing commenced. A total of ten successful trails were subsequently recorded for each participant, with three footprints being recorded per trial on the pressure platform, thereby comprising 30 footprints (15 left foot and 15 right foot) per participant that were analysed regarding pressure and impulse values. The two-step gait initiation protocol was implemented which was proven to be a valid and reliable means of assessing gait. Participants were instructed to walk at a comfortable walking speed between 1.19 – 1.60 m/s to ensure conformity between all participants as between-trial gait velocities were proven to be significantly variable. The foot was subdivided into ten anatomical areas focusing on the great toe, lesser toes, metatarsal 1, metatarsal 2, metatarsal 3, metatarsal 4, metatarsal 5, midfoot, medial heel and lateral heel. These ten areas were then grouped into one of three regions, namely the forefoot region (great toe, lesser toes, and all five metatarsal head areas), midfoot region (midfoot area), and rearfoot/heel region (medial and lateral heel areas). Once all relevant data was gathered, corrected and analysed it was used to establish normative data tables pertaining to the various gender and race groups. Results: Of the ten individual pressure and impulse areas, the second and third metatarsal heads demonstrated the highest mean peak pressure and impulse values. Once grouped into one of the three regions, the heel region was ascribed with the largest impulse and pressure values. It was established that statistically and practically significant racial pressure differences were apparent in the left and right forefoot and midfoot regions, with black and coloured individuals yielding the highest values, whereas white participants yielded the lowest. The same was true with regards to impulse figures in that both statistical and practical significant levels were established in the forefoot and midfoot regions. Black and coloured participants exhibited larger impulse values than the white participants. The level of physical activity was found to be associated with both pressure and impulse values over the various regions of the foot. Black individuals that were largely inactive as well as moderately active coloured participants yielded the highest pressure and impulse values, which were found to be statistically and practically significant over the forefoot regions. Conversely, white participants of all physical activity levels as well as coloured participants of both low and high physical activity levels exhibited the lowest pressure values over the forefoot region, which were also found to be statistically and practically significant. The anthropometric variables of height, weight and BMI were found to relate statistically to pressure and impulse values under the various regions of the foot, but none were found to be of any practical significance (r < .30). Conclusion: It was clearly established that both gender and race specific differences existed regarding plantar pressure and impulse values of the normal foot. Plantar pressure and impulse values were also associated with the level of physical activity of the individual, thereby indicating that the level of physical activity could be a contributing factor to altered pressure and impulse values. Anthropometric variables such as height, weight and BMI could not solely account for the variances observed in pressure and impulse. Further research is required to determine whether pressure or impulse values above or below those obtained predispose an individual to injury and to contrast between various activity or sporting codes and the effect of these on plantar pressure and impulse figures. Finally, from the collected data one was able to establish reference tables for the specific gender and race groups for both plantar pressure and impulse values.

Abstract (sommario):

Background: Despite a lack of consensus on its utility, clinicians have traditionally relied on plantar pressure (PP) to predict ulcer risk and prescribe interventions in individuals with diabetic peripheral neuropathy (DPN). Joint kinematics and kinetics have the potential to contribute to DPN assessment and treatment, however previous studies have not accounted for walking speed nor integrated a full-body analysis with a detailed foot model. Purpose: To assess PP and gait alterations in DPN by controlling walking speed and incorporating a multisegment foot model into a full-body gait analysis. We hypothesize that hip and ankle kinetics will be altered consistent with distal muscle weakness. Methods: Ten subjects with DPN (height: 178.79 ± 8.55 cm, weight: 108.78 ± 16.67 kg, age: 61.5 ± 13.53 years), and 10 healthy matched controls (height: 180 ± 6.37 cm, weight: 92.87 ± 14.5 kg, age: 59.4 ± 7.5 years) participated in this cross-sectional study. Fifty-six reflective markers were attached to each subject according to a full-body model, including a multisegment foot. Subjects walked at a controlled speed (1 m/s) while plantar pressure, kinematic and kinetic data were collected. Functional data analysis was used to compare kinematic and kinetic data between groups, while independent t-tests and a Benjamini-Hochburg procedure was used to compare plantar pressure and joint work metrics. Results: Individuals with DPN presented with a delayed transition from hip extension to hip flexion moment and a decrease in peak hip flexion moment. There were no major changes found at the knee. There was an increase in peak dorsiflexion angle and delayed power generation in both the ankle and midtarsal joints. DPN subjects also showed a decreased midtarsal positive work. The only significant PP metric found was a decrease in peak PP under the lateral toes. Conclusion: Findings demonstrated that individuals with DPN use a hip compensation mechanism to overcome distal muscle weakness. Ankle and midfoot alterations are consistent with muscle weakness, requiring proximal compensations. Joint mechanics were more informative than PP measurements and may provide additional insight into DPN assessment and treatment.

Abstract (sommario):

Hallux valgus and hallux limitus are two common foot pathologies that may require surgical intervention. While the modified Austin bunionectomy and the Youngswick osteotomy/cheilectomy respectively, are often used to correct these conditions, insufficient research has been published regarding the effects of these procedures on plantar pressure distribution of the foot. This thesis involves a series of six studies investigating topics relating to radiographic measurements and plantar pressure distribution over a two-year period, in normal feet and in hallux valgus and hallux limitus feet before and after corrective surgery.A review of the literature is presented relating to the development of plantar pressure measurement technology, the aetiology and surgical management of hallux valgus and hallux limitus, the reliability of the EMED system used in the studies, and the related clinical uses of plantar pressure measurement.An initial study was designed to investigate the reliability measurements using a simplified two-step method of data collection as compared to the traditional mid-gait technique of ten normal asymptomatic subjects. Intra-class correlation coefficients were calculated and compared for the pressure variables of contact area, contact time, maximum force and peak pressure of ten regions of the foot.A study to determine normal reference range values for the EMED-SF system was then conducted using thirty healthy subjects and the two-step method of data collection. Descriptive statistical reporting of peak pressure, mean pressure and pressure-time- integrals were presented for ten regions of the foot.Three related studies on radiographic and plantar pressure measurement differences, and their relationships were made using thirty normal, hallux valgus and hallux limitus feet. Various angular and linear radiographic measurements were tested for intra-rater reliability of measurement and pressure variables of peak pressure, mean pressure and pressure-time-integral of 10 regions of the foot were recorded and one way analysis of variance employed to assess any significant differences.Finally, two independent two-year prospective studies were designed to investigate the effects of the modified Austin bunionectomy for hallux valgus and the Youngswick osteotomy/cheilectomy for hallux limitus on plantar pressure distribution of the forefoot. In addition, fundamental radiographic measurement changes of the forefoot of hallux valgus subjects and range of motion changes of the first metatarsophalangeal joint of hallux limitus subjects were conducted. Thirty-six healthy volunteers acted as control subjects, 31 subjects (44 feet) with hallux valgus and 17 subjects (23 feet) with hallux limitus were included in the study. Using an EMED-SF system, plantar pressure variables of peak pressure, pressure-time-integral, contact time, maximum force and force-time-integral were recorded at six regions of the forefoot, pre-operation and repeated at three, six, 12, 18 and 24-months post-operation for surgical subjects. Control subjects were tested at zero and 24-months. Descriptive statistics, multivariate and univariate analysis of variance with contrasts, t-tests of significance and correlations between certain measurement parameters were used in the analysis of the results.The findings of these studies suggest that the two-step method of data collection of plantar pressure measurements is more reliable that the traditional mid-gait technique for most pressure variables. Consequently, the two-step method was employed as the preferred method of data collection in this series of studies.With respect to radiographic differences between normal, hallux valgus and hallux limitus, it appears that hallux valgus feet have significant increases in metatarsus primus varus and first metatarsal protrusion distance, while hallux limitus feet have increased hallux abductus interphalangeal angles. Comparison of pressure variables between each group demonstrate hallux valgus feet have a medial localisation of peak pressure beneath the first, second and third metatarsal heads, suggesting that hyperpronation of the foot is associated with the development of hallux valgus. Hallux limitus feet on the other hand, show increased pressure beneath the hallux, third and fourth metatarsals and lesser toes, indicating a more lateral locus of pressure loading, suggestive -of the foot functioning in a more supinated position. No significant relationship was found between any radiographic parameter and pressure variable tested in either group of subjects.Plantar pressure measurement changes show the greatest variation during the initial three to six months following surgical treatment of hallux valgus and hallux limitus. The Youngswick osteotomy/cheilectomy for the treatment of hallux limitus produces near-normal range of motion of the first metatarsophalangeal joint. Pressures of the first metatarsal head remain relatively constant over the period of measurement, while a significant reduction of the hallux and lateral metatarsals were noted, related to increased dorsiflexion of the hallux. Pressures of the second metatarsal head remained significantly above pre-operation levels. The modified Austin bunionectomy for the treatment of hallux valgus produced 24-month radiographic changes consistent with accepted values. Pressure variables of the hallux reduced to normal values, with the first metatarsal head demonstrating an initial significant decrease and subsequent increase by twelve months post-operation to remain with the second metatarsal head at relatively similar values to pre-operation measurements.The research demonstrates the two-step method of data collection is a viable means of obtaining reliable plantar pressure measurement data in the clinical situation. The investigations into radiographic and plantar pressure distribution indicate that structural radiographic and functional differences exist between normal, hallux valgus and hallux limitus feet. However, no relationship could be found between any of the radiographic parameters and pressure variables tested.The modified Austin bunionectomy for hallux valgus significantly reduced fundamental radiographic measurements to accepted post-operative values, while the Youngswick procedure for hallux limitus significantly increased the amount of post-operative dorsiflexion of the hallux to normal values. The research demonstrates that immediate and longer-term functional changes to the forefoot occur following the surgical treatment of hallux valgus and hallux limitus, however plantar pressure measurements do not return to normal values. No correlation was found between plantar pressure measurements and post- operative radiographic measurements in the hallux valgus group. However, the increased amount of dorsiflexion of the hallux post-operatively in the hallux limitus group was correlated with reduced lateral loading of the forefoot. Post-operation changes of plantar pressure distribution indicate that the rehabilitative period required to achieve stable foot function is between twelve to eighteen months. Furthermore, plantar pressure measurement technology offers the clinician a useful tool to monitor foot function prior to and following therapeutic intervention.

Abstract (sommario):

Introduction: Instrumented gait analysis and inverse dynamics are commonly used in research and clinical practice to calculate lower extremity joint kinetics, such as power and work. However, multisegment foot (MSF) model kinetics have been limited by ground reaction force (GRF) measurements. New technology enables simultaneous capture of plantar pressure and shear stress distributions but has not yet been used with motion capture. Integrating MSF models and pressure/shear measurements will enhance the analysis of foot joint kinetics. The purpose of this study was to develop methodology to integrate these systems, then analyze the effects of speed on foot joint kinetics. Methods: Custom software was developed to synchronize motion capture and pressure/shear data using measured offsets between reference frame origins and time between events. Marker trajectories were used to mask pressure/shear data and construct segment specific GRFs. Inverse dynamics were done in commercial software. Demonstrative data was from 5 healthy adults walking unshod at 3 fixed speeds (1.0, 1.3, and 1.6 m/s, respectively) wearing retroreflective markers according to an MSF model. Plantar shear forces and ankle, midtarsal, and first metatarsophalangeal (MTP) joint kinetics were reported. Speed effects on joint net work were evaluated with a repeated measures ANOVA. Results: Plantar shear forces during stance showed some spreading effects (directionally opposing shear forces) that relatively were unaffected by walking speed. Midtarsal joint power seemed to slightly lag behind the ankle, particularly in late stance. Net work at the ankle (p = 0.024), midtarsal (p = 0.023), and MTP (p = 0.009) joints increased with speed. Conclusions: Functionally, the ankle and midtarsal joints became more motorlike with increasing speed by generating more energy than they absorbed, while the MTP joint became more damperlike by absorbing more energy than it generated. System integration appears to be an overall success. Limitations and suggestions for future work are presented.

Abstract (sommario):

Human footwear is not yet designed to optimally relieve pressure on the heel of the foot. Proper foot pressure assessment requires personal training and measurements by specialized machinery. This research aims to investigate and hypothesize about Preferred Transition Speed (PTS) and to classify the gait phase of explicit variances in walking patterns between different subjects. An in-shoe wearable pressure system using Android application was developed to investigate walking patterns and collect data on Activities of Daily Living (ADL). In-shoe circuitry used Flexi-Force A201 sensors placed at three major areas: heel contact, 1st metatarsal, and 5th metatarsal with a PIC16F688 microcontroller and Bluetooth module. This method provides a low-cost instantaneous solution to both wear and records plantar foot simultaneously. Data acquisition used internal local memory to store pressure logs for offline data analysis. Data processing used the perpendicular slope to determine peak pressure and time of index. Statistical analysis can utilize to discover foot deformity. The empirical results in one subject showed weak linearity between normal and fast walk and a significant difference in body weight acceptance between normal and slow walk. In addition, T-test hypothesis testing between two healthy subjects, with , illustrated a significant difference in their Initial Contact pressure and no difference between their peak-to-peak time interval. Preferred Transition Speed versus VGRF was measured in 19 subjects. The experiments demonstrated that vertical GRF averagely increased 18.46% when the speed changed from 50% to 75% of PTS with STD 4.78. While VGRF increased 21.24% when the speed changed from 75% to 100% of PTS with STD 7.81. Finally, logistic regression between 12 healthy subjects demonstrated a good classification with 82.6% accuracy between partial foot bearing and their normal walk.
