Fifty years ago, the International Society for Prosthetics and Orthotics was founded in recognition that this unique niche in rehabilitation would benefit from multidisciplinary interactions between specialists in engineering, therapy, and medicine.Since then, field evolved from having a craft orientation toward a technology and clinical specialty. This anniversary provides an opportunity to look back on advances in prosthetics and orthotics, and the clear impact they have had on changing the skills needed by the prosthetist/orthotist as new technology and techniques have emerged. The balance has clearly shifted from mechanical skills to clinical care. The training and skills of the prosthetist/orthotist remain unique and valued in the rehabilitation team, and the primary motivation remains the same as it has been since the creation of the International Society for Prosthetics and Orthotics: the application of external devices where they are suitable to address the many varied needs of persons with disability. This historical perspective puts into context why and how the profession has changed, while also reinforcing that it is the goals set for restoring patient functions that best defines what it is to be a prosthetist/orthotist, not the means we use.

Background and Objectives: This study aimed to determine the prevalence rate of musculoskeletal disorders and evaluate the body position in routine tasks among orthotists and prosthetists. Methods: Forty orthotists and prosthetists were included. The scores of the Nordic Musculoskeletal Questionnaire and the Rapid Entire Body Assessment were used to determine the prevalence rate of musculoskeletal disorders and analyze the work position of orthotists and prosthetists, respectively. An examiner evaluated 10 working postures that were dominantly used every day, in each orthotist and prosthetist. Results: Among the orthotists, 55.6% of men and 47% of women suffered from pain in the trunk, neck, and lower limbs. Nearly similar results were seen in the upper limbs (74.1% men and 45.5% women). Such high prevalence rates were not seen in prosthetists. The analysis of the Rapid Entire Body Assessment scores based on the working task and gender of the orthotist and prosthetist showed that more than 60% of the workers achieved a score of 4 to 7 approximately in half of the tasks. It shows the medium risk of musculoskeletal disorders, thus, corrective action is necessary. Conclusion: Based on the findings, musculoskeletal disorders are highly prevalent among orthotists and prosthetists, especially in the orthotist workers. To reduce these disorders, it is recommended to add ergonomic topics and training courses for working with devices to increase the knowledge of specialists and apply and select practical tools based on the principles of ergonomics.

The co-construction of a psychology module for a postgraduate training course in orthotics/prosthetics is socially constructed for the first time in Southern African history. This paper elucidates the integration of theory and practice in a model for the development of a professional identity as orthotist/prosthetist. In creating a context where trainees can learn to develop their practice while also enabling them to deconstruct notions of ‘expert knowledge’, orthotist/prosthetists move from a position of scientist-practitioner to negotiating an alternative position of reflective practitioner. In the process of co-constructing knowledge, an alternative story of teaching and learning evolves. The result is a celebration of life as it is really lived by health professionals.

Background: Evidence-based recommendations are lacking for prosthetic and orthotic services in low- and lower-middle-income countries. Objectives: The aim of this study was to compare and synthesise findings related to experiences of prosthetic and orthotic service delivery in Tanzania, Malawi, Sierra Leone and Pakistan from the perspective of local professionals. Study design: This is a qualitative inductive study. Methods: A total of 49 associated prosthetists/orthotists and prosthetic/orthotic technicians participated in individual interviews. The second-order concept analysis was applied to the data. Results: Four common themes emerged: low awareness and prioritisation of prosthetic and orthotic services; difficulty managing specific pathological conditions and problems with materials; limited access to prosthetic and orthotic services; and the need for further education and desire for professional development. A further theme was unique to Sierra Leone: people with disabilities have low social status. Conclusion: Local professionals felt unable to deliver high-quality prosthetic and orthotic services. Prosthetic and orthotic education needs to be adjusted to various countries’ regulations to be recognised as allied health professions. Rehabilitation and prosthetic and orthotic service delivery need to be further integrated in low- and lower-middle-income countries’ regular health systems to increase effective person-centred rehabilitation and to address governments’ low awareness and low prioritisation of prosthetic and orthotic services. Clinical relevance The results can inform international guidelines and curriculum development for associate prosthetist/orthotist education to better prepare graduates for the clinical scenario and attempts to improve prosthetic and orthotic service delivery programmes in low- and lower-middle-income countries.

Background The prosthetic and orthotic industry typically provides an artisan “hands-on” approach to the assessment and fitting of orthopedic devices. Despite growing interest in digital technology for prosthetic and orthotic service provision, little is known of the quantum of use and the extent to which the current pandemic has accelerated the adoption. Objective This study’s aim is to assess the use of digital technology in prosthetics and orthotics, and whether its use can help overcome challenges posed by the current COVID-19 pandemic. Methods A web-based survey of working prosthetists, orthotists, and lower limb patients was conducted between June and July 2020 and divided into three sections: lower limb amputees, prosthetist and orthotist (P&O) currently using digital technologies in their practice, and P&O not using any digital technology. Input was sought from industry and academia experts for the development of the survey. Descriptive analyses were performed for both qualitative (open-ended questions) and quantitative data. Results In total, 113 individuals responded to the web-based survey. There were 83 surveys included in the analysis (patients: n=13, 15%; prosthetists and orthotists: n=70, 85%). There were 30 surveys excluded because less than 10% of the questions were answered. Out of 70 P&Os, 31 (44%) used digital technologies. Three dimensional scanning and digital imaging were the leading technologies being used (27/31, 88%), primarily for footwear (18/31, 58%), ankle-foot orthoses, and transtibial and transfemoral sockets (14/31, 45%). Digital technology enables safer care during COVID-19 with 24 out of 31 (77%) respondents stating it improves patient outcomes. Singapore was significantly less certain that the industry's future is digital (P=.04). The use of virtual care was reported by the P&O to be beneficial for consultations, education, patient monitoring, or triaging purposes. However, the technology could not overcome inherent barriers such as the lack of details normally obtained during a physical assessment. Conclusions Digital technology is transforming health care. The current pandemic highlights its usefulness in providing safer care, but digital technology must be implemented thoughtfully and designed to address issues that are barriers to current adoption. Technology advancements using virtual platforms, digitalization methods, and improved connectivity will continue to change the future of health care delivery. The prosthetic and orthotic industry should keep an open mind and move toward creating the required infrastructure to support this digital transformation, even if the world returns to pre–COVID-19 days.

Background:Little research has been undertaken into occupational health and safety in the Prosthetics and Orthotics profession.Objectives:To identify physical, psychosocial and environmental workplace experiences of Prosthetists and Orthotists in organisational settings.Study design:Qualitative methodology, cross-sectional design, using thematically analysed data collected from focus groups.Methods:Focus groups explored workplace and work experiences across varied Prosthetic and Orthotic settings. Data were thematically analysed to identify physical, psychosocial and environmental workplace experiences.Results:Three major themes, Demands of Work Practice, Impacts on the Individual and Job Design, were identified as problematic. A latent theme Perceptions of Others of P&O highlighted a lack of understanding of the Prosthetics and Orthotics job role outside the profession.Conclusion:This first study of occupational health and safety in the Prosthetics and Orthotics profession identifies a number of important physical and psychosocial issues, including characteristics that have been previously identified as risk factors for work-related musculoskeletal disorders. Findings from the study indicate that some Australian organisations lack understanding of the Prosthetics and Orthotics job role, which results in inappropriate expectations of Prosthetics and Orthotics professionals. Preventing injuries and retaining experienced Prosthetists and Orthotists in the workplace is vital for the profession, and as a result, issues raised in this study require further exploration and then development of appropriate management strategies.Clinical relevanceThis is the first study characterising the experiences of work and risk of injuries in Prosthetists and Orthotists. Preventing injuries and retaining experienced Prosthetists and Orthotists in the workplace is vital for the international profession.

In the inaugural edition of Prosthetics and Orthotics International in 1977, Dr Sidney Fishman identified the Psychological Sciences as one of six indispensable areas of skill and knowledge in professional prosthetic–orthotic practice. Since then, there have been substantial changes and developments in the complexity and capabilities of assistive technologies, greater emphasis on understanding the relationships between people and enabling technologies, growing recognition of the importance of the contexts and environments that support their use, and changes in both health care services and the professional development of prosthetists and orthotists. The aim of this narrative review is to reflect on the role of Prosthetics and Orthotics International in shaping the evolving understanding of psychology in prosthetics and orthotics. There remains considerable potential and opportunity for the development and application of psychology in addressing the challenges of disability globally. However, a broad interpretation and application of the principles of rehabilitation psychology are needed if we are to meaningfully incorporate psychological science into the knowledge that informs prosthetic and orthotic practice.

Background: Education and training in prosthetics and orthotics typically comply with International Society for Prosthetics and Orthotics standards based on three categories of prosthetic and orthotic professionals. Objective: This scoping study sought to describe the evidence base available to answer the question, How are prosthetic and orthotic services influenced by the training of staff providing them? Study design: Scoping review. Methods: A structured search of the peer-reviewed literature catalogued in major electronic databases yielded 3039 papers. Following review of title and abstract, 93 articles were considered relevant. Full-text review reduced this number to 25. Results: Only two articles were identified as providing direct evidence of the effects of training and education on service provision. While both suggested that there was an impact, it is difficult to see how the more specific conclusions of either could be generalised. The other 23 articles provide a useful background to a range of issues including the specification of competencies that training programmes should deliver (3 articles), descriptions of a range of training programmes and the effects of training and education on student knowledge and skills. Conclusion: Although it is considered axiomatic, the service quality is dependent on practitioner education and training. There is insufficient evidence to establish whether levels of training and education in prosthetics and orthotics have an effect on the quality of prosthetic and orthotic services. Clinical relevance There is very little evidence about the effects of training and education of prosthetists and orthotists on service quality. While this is a somewhat negative finding, we feel that it is important to bring this to the attention of the prosthetics and orthotics community.

Background: To be able to meet social harmony in a continuously globalizing world, intercultural competencies are important to possess as an individual. Thus, it is also important for Certified Prosthetists and Orthotists (CPOs) and other health care providers since they meet many diversities in connection to their work. Aim: The aim of this study is to investigate Danish CPOs’ experience and perception of their intercultural competencies in the treatment of immigrants. Method: This study is a qualitative interview study using a phenomenological approach. Semi-structured interviews are used to collect the data from five CPOs working in Danish clinics. A content analysis, with an inductive approach, is used for the analysis. Findings: From the analysis of the participant interviews, seven sub-categories were found and further divided into three categories: Treatment, work environment, and development of competencies. These contribute to describe the main category and the aim of this study. Conclusion: The Danish CPOs, who participated in this study, experienced that they did not treat immigrants differently than non-immigrants. However, they experienced that some challenges could be connected to the treatment of immigrants, such as communication difficulties, but they all had a perception, that they used specific tools and strategies to accommodate these challenges. Furthermore, they all experienced that their intercultural competencies had improved with experience, but most of them were also interested in further development of their competencies.

Aim: The overall aim of this thesis was to generate further knowledge about prosthetic and orthotic services in developing countries. In particular, the thesis focused on patient mobility and satisfaction with prosthetic and orthotic devices, satisfaction with service delivery, and the views of staff regarding clinical practice and education. Methods: Questionnaires, including QUEST 2.0, were used to collect self-reported data from 83 patients in Malawi and 139 patients in Sierra Leone. In addition, 15 prosthetic/orthotic technicians in Sierra Leone and 15 prosthetists/orthotists in Pakistan were interviewed. Results: The majority of patients used their prosthetic or orthotic devices (90% in Malawi, and 86% in Sierra Leone), but half of the assistive devices in use needed repair. Approximately one third of patients reported pain when using their assistive device (40% in Malawi and 34% in Sierra Leone). Patients had difficulties, or could not walk at all, with their prosthetic and/or orthotic device in the following situations; uneven ground (41% in Malawi and 65% in Sierra Leone), up and down hills (78% in Malawi and 75% in Sierra Leone), on stairs (60% in Malawi and 66% in Sierra Leone). Patients were quite satisfied or very satisfied with their assistive device (mean 3.9 in Malawi and 3.7 in Sierra Leone out of 5) and the services provided (mean 4.4 in Malawi and 3.7 in Sierra Leone out of 5), (p<0.001), but reported many problems (418 comments made in Malawi and 886 in Sierra Leone). About half of the patients did not, or sometimes did not, have the ability to access services (71% in Malawi and 40% in Sierra Leone). In relation to mobility and service delivery, orthotic patients and patients using above-knee assistive devices in Malawi and Sierra Leone had the poorest results. In Sierra Leone, women had poorer results than men. The general condition of devices and the ability to walk on uneven ground and on stairs were associated with both satisfaction of assistive devices and service received. Professionals’ views of service delivery and related education resulted in four themes common to Sierra Leone and Pakistan: 1) Low awareness and prioritising of prosthetic and orthotic services; 2) Difficulty managing specific pathological conditions and problems with materials; 3) The need for further education and desire for professional development; 4) Desire for improvements in prosthetic and orthotic education. A further two themes were unique to Sierra Leone; 1) People with disabilities have low social status; 2) Limited access to prosthetic and orthotic services. Conclusion: High levels of satisfaction and mobility while using assistive devices were reported in Malawi and Sierra Leone, although patients experienced pain and difficulties when walking on challenging surfaces. Limitations to the effectiveness of assistive devices, poor comfort, and limited access to follow-up services and repairs were issues that needed to be addressed. Educating prosthetic and orthotic staff to a higher level was considered necessary in Sierra Leone. In Pakistan, prosthetic and orthotic education could be improved by modifying programme content, improving teachers’ knowledge, improving access to information, and addressing issues of gender equality.

Existing methods that use a fringe projection technique for orthotic and prosthetic designs produce good results for the trunk and lower limbs; however, the devices used for this purpose are expensive. This thesis investigates the use of an inexpensive passive method involving 3D surface reconstruction from video images taken at multiple views. The design and evaluation methodology, consisting of a number of techniques suitable for orthotic and prosthetic design, is developed. The method that focuses on fitting the reference model (3D model) of an object to the target data (3D data) is presented. The 3D model is obtained by a computer program while the 3D data uses the shape-from silhouette technique in an approximately circular motion.

Objective: To gather knowledge related to patient satisfaction and mobility with lower limb prosthetic and orthotic devices and to investigate satisfaction with services received. Another purpose of this study is to analyze potential differences between orthotic and prosthetic patients in relation to patient satisfaction and mobility. Design: Cross-sectional study Subjects: 21 participants with a mean age of 58 (SD 16) with an average duration of use of devices of 10 (SD 10) years. 12 out of the 21 participants were orthotic users and 9 were prosthetic users. Methods: Patients were asked to complete two questionnaires, one regarding satisfaction with assistive device and service (QUEST 2.0) and one regarding mobility. Results: Patients mean score regarding satisfaction with assistive device and service were 4.0 (SD 0.8) and 4.2 (SD 1.0) respectively. 91% reported that they had the ability to walk at least 100 meters with their assistive device. The areas where participants experienced most difficulties were walking on uneven ground (70%), walking up and down a hill (57%) and walking on stairs (57%). Conclusion: Overall this study demonstrates that participants were quite satisfied with their assistive device and the service received by the P&O clinic. No statistically significant differences regarding satisfaction with assistive device and service, or mobility, were found between prosthetic and orthotic participants.

Powered orthotic devices can be used to restore mobility to the impaired user, and may thereby assist them in daily living tasks. An investigation is performed herein to examine the feasibility of a powered lower-limb orthotic in assisting the sit-to-stand task by 50% of the required torque. Feasibility is considered via simulation. A three-link sit-to-stand model, which is driven by kinematic data, is developed. Models of a Pneumatic Muscle Actuator and a DC motor are used to determine which of the two technologies can make a more appropriate contribution to the sit-to-stand task. Simulation revealed that both the Pneumatic Muscle Actuator and the DC motor are reasonable actuator choices, and neither limited the ability to achieve 50% torque assistance. The ability to assist the task was, however, limited by the ability to derive a control signal for the actuator from the user-orthotic interface. It was concluded that the user-orthotic interface requires further investigation. It was also found that while both actuator technologies are suitable for contributing 50% of the required torque, the Pneumatic Muscle Actuator is preferable due to its ability to scale to greater torques.

Annotation:

The electromyogram (EMG) signal is desired to be used as a control signal for applications such as multifunction prostheses, wheelchair navigation, gait generation, grasping control, virtual keyboards, and gesture-based interfaces [25]. Several research studies have attempted to relate the electromyogram (EMG) activity of the forearm muscles to the mechanical activity of the wrist, hand and/or fingers [41], [42], [43]. A primary interest is for EMG control of powered upper-limb prostheses and rehabilitation orthotics. Existing commercial EMG-controlled devices are limited to rudimentary control capabilities of either discrete states (e.g. hand close/open), or one degree of freedom proportional control [4], [36]. Classification schemes for discriminating between hand/wrist functions and individual finger movements have demonstrated accuracy up to 95% [38], [39], [29]. These methods may provide for increased amputee function, though continuous control of movement is not generally achieved. This thesis considered proportional control via EMG-based estimation of finger forces with the goal of identifying whether multiple degrees of freedom of proportional control information are available from the surface EMG of the forearm. Electromyogram (EMG) activity from the extensor and flexor muscles of the forearm was sensed with bipolar surface electrodes and related to the force produced at the four fingertips during constant-posture, slowly force-varying contractions from 20 healthy subjects. The contractions ranged between 30% maximum voluntary contractions (MVC) extension and 30% MVC flexion. EMG amplitude sampling rate, least squares regularization, linear vs. nonlinear models and number of electrodes used in the system identification were studied. Results are supportive that multiple degrees of freedom of proportional control information are available from the surface EMG of the forearm, at least in healthy subjects. An EMG amplitude sampling frequency of 4.096 Hz was found to produce models which allowed for good EMG amplitude estimates. Least squares regularization with a pseudo-inverse tolerance of 0.055 resulted in significant improvement in modeling results, with an average error of 4.69% MVC-6.59% MVC (maximum voluntary contraction). Increasing polynomial order did not significantly improve modeling results. Results from smaller electrode arrays remained fairly good with as few as six electrodes, with the average %MVC error ranging from 5.13%-7.01% across the four fingers. This study also identified challenges in the current experimental study design and subsequent system identification when EMG-force modeling is performed with four fingers simultaneously. Methods to compensate for these issues have been proposed in this thesis.

Annotation:

Motor control of any movement task involves the integration of neural, muscular and skeletal systems. This integration must occur throughout the sensorimotor system and focus its efforts on controlling the system endpoint, e.g. the foot during locomotion. A person with a uni-lateral trans-tibial amputation has lost the foot, ankle joint, and muscles crossing those joints, hence the residuum becomes the new terminus of the motor system. The amputee must now adjust to the additional challenges of utilizing a compromised motor system as well as the challenges of controlling an external device, i.e. prosthesis, through the mechanical interface between the residuum and prosthetic socket. The obvious physical and physiologic asymmetries between the sound and amputated limbs are also involved in strategies for locomotion involving kinematic and kinetic asymmetries (Winter&Sienko, 1988). There are many questions as to why these asymmetric locomotor strategies are selected and what factors may be influencing that strategy. Factors influencing a change in locomotor strategy could be related to 1) the central nervous system accounting for the loss of sensorimotor feedback, 2) the altered mechanics of this new human/prosthetic system, or some combination of these factors. Understanding how the human motor system adjusts to the amputation and to the addition of an external mechanical device can provide useful insight into how robust the human control system may be and to adaptations in human motor control. This research uses a group of individuals with a uni-lateral trans-tibial amputation and a group of intact individuals using an Ankle Foot Orthosis (AFO) performing a cycling task to understand the "motor adjustments" necessary to utilize an external device for locomotion. Results of these experiments suggest 1) the motor system does account for the activation-contraction dynamics when coordinating muscle activity post amputation, 2) the motor system also changes joint kinetics and muscle activity, 3) these changes are related to control of the interface between the limb and the external device, and 4) the motor system does not alter kinetic asymmetries when kinematic asymmetries are minimized, contrary to a common practice in rehabilitation (Kapp, 2004). Results suggest that control of the external device, i.e. prosthesis or AFO, via the interface between the limb and the device reflect "motor adjustments" made by the nervous system and may be viewed in the context of tool use. Clinical goals in rehabilitation currently focus on minimizing gait deviations whereas the clinical application of these results suggest these deviations from normal locomotion are motor adjustments necessary to control a tool, i.e. prosthesis, by the motor system. Examining amputee locomotion in the context of tool use changes the clinical paradigm from one designed to minimize deviations to one intended to understand this behavior as related to interface control of the device thereby shifting the focus to improving function of the limb/prosthesis system.

Annotation:

This thesis proposes an algorithm that determine the geometry of 3D-printed, custom-designed spring element bands made of thermoplastic elastomer (TPE) for use in a wearable orthotic device to aid in the physical therapy of a human hand exhibiting spasticity after stroke. Each finger of the hand is modeled as a mechanical system consisting of a triple-rod pendulum with nonlinear stiffness at each joint and forces applied at the attachment point of each flexor muscle. The system is assumed quasi-static, which leads to a torque balance between the flexor tendons in the hand, joint stiffness and the design force applied to the fingertip by the 3D-printed spring element. To better understand material properties of the spring element’s material, several tests are performed on TPE specimens printed with different infill geometries, including tensile tests and cyclic loading tests. The data and stress-strain curves for each geometry type are presented, which yield a nonlinear relationship between stress and strain as well as apparent hysteresis. Polynomial curves are used to fit the data, which allows for the band geometry to be designed. A hypothetical hand is presented along with how input measurements might be taken for the algorithm. The inputs are entered into the algorithm, and the geometry of the bands for each finger are generated. Results are discussed, and future work is noted, providing a means for the design of a customized orthotic device.

The main purpose of this research is to design a set of hip flexion-extension coupling ratio mechanism for paraplegic and HD/HP patients. In clinical experiences, the treatment for paralysis of lower extremities and HD/HP patients is the most challenging issue. Compared with knee joint mechanism, the hip joint needs novel design in priority. The hip mechanism of reciprocating gait orthosis (RGO) can only apply flexion/extension motion. The limitation leads to patients’ compensatory movement. So the mechanism needs to have the ability to adjust higher flexion-extension coupling ratio(FECR) automatically for different phases. First, we use Lagrange equation to establish simple human model. By substituting different initial conditions, the solution can be used to design higher hip coupling ratio mechanism which is better than conventional mechanism. In practical application, we investigate the real coupling ratio and the influence of 1:1 coupling ratio mechanism on normal people by motion analysis method. We find that the abnormal constrain may be one of the main reason of slow walking speed. Finally, we give suggestions for more mature mechanism which can work stably on subjects in the future.

Abstract Prosthetists face a daunting number of decisions that directly affect an amputee’s ability to walk and indirectly affect the overall quality of life of that amputee. In addition, the lack of resources in low-income countries provides a barrier to receive care after an amputation, and approximately 80% of amputees in low-income countries lack appropriate prosthetic care. In this research, we are motivated to understand what factors affect the decision-making strategies of prosthetists and podiatrists when prescribing prosthetics and orthotics to partial foot amputees. This work establishes a decision-making framework as a step towards automated methods that may reduce the complexities and decision-making burden of prosthetic prescription, ultimately increasing the efficiency of prosthetic prescription in low-resourced areas. A decision-making model is proposed based on an extensive literature review of over 100 papers. The proposed model is compared to qualitative data regarding decision-making strategies during prosthetic or orthotic prescription collected from nine prosthetists, surgeons, and other healthcare professionals directly involved in amputee care. Changes to the proposed model are described and future work exploring the role of automated methods to support decision-making in the context of prosthetics is discussed.

Abstract Approximately, 40 million amputees reside in the rural parts of Low-Income Countries (LICs), and 95% of this population do not have proper access to prosthetic devices and rehabilitation services. A proper prosthetic prescription requires a clear understanding of the patient’s ambulation, goals, cultural and societal norms, locally available prosthetic materials, etc., which can be accomplished only by a local prosthetist. However, due to the lack of prosthetic schools and training centers in LICs, the rural parts lack well-trained amputee care providers. Hence there is a need to educate the prosthetists and prosthetic technicians in the LIC, specifically in the rural regions. To accomplish this, the current research proposes a decision-support tool to aid decision-making during prescription and educate prosthetists. A controlled study was conducted with expert and novice prosthetists to compare effective decision-making strategies. Results suggest that experts leverage distinct decision-making strategies when prescribing prosthetic and orthotic devices; in comparison, novices exhibited less consistent patterns of decision-making tendencies. By modeling the decision-making strategies of expert prosthetists, this work lays the foundation to develop an automated decision support tool to support decision-making for prosthetists in LICs, improving overall amputee care.

Most people don’t think twice about the energy required for walking, except when interested in burning calories during exercise. However, someone needing to depend on active orthotics, or prosthetics, due to partial paralysis or other weakness of the lower extremities, would find energy efficiency of great interest if it meant the range of use was limited by the energy required to power the assistive devices.
