Повний текст джерелаThis work is an exploratory theoretical study on systematic design of special wheelchair seating systems, emphasizing its conceptual and functional aspects. According to the principles of assistive technology - which consists in the use of technologies applied to the caring of the needs of people with disabilities - the objectives of technical aids should be the promotion of optimal individual functionality. Thus, a literature review has been made on the theme of postural seating clinic, and the factors related to the health, the functionality, and the comfort or discomfort in the sitting position, allowing the identification of many explicit and implicit needs. By using the Systematic Design approach of Pahl & Beitz, complemented by some principles of Axiomatic Design and TRIZ, a functional requirements list has been made, consisting in the mapping between the customer needs in the customer domain and the functional requirements in the functional domain. In the next step, a functional structure has been created, showing the main functional elements and connections of the seating system, followed by the proposal of some working principles regarding the main identified sub-functions, including the analysis of analog technical systems of other technological fields. It was concluded that immobility is the main causative factor leading to the many functional and health problem associated with the sitting position, and therefore the main function of special seating systems must be to allow and actively promote frequent position changes. Moreover, it has become evident that information flows have a capital importance in proper functioning of seating systems, since they convey the homeostatic purpose of the movements being made, in order to continually redistribute and alleviate the local soft tissue deformations, and to promote the selective stabilization and motion of body segments that permit functional motor action.

Elderly adults with lower limb disorders sitting on a wheelchair for an extended period of time may experience numerous complications. Critical complications in clinical practice include back pain, pressure ulcers, and decreased pulmonary function. Wheelchair seating system is a key factor that influences spinal angle, back muscle activation, interface pressure, pulmonary function, and subjective discomfort. Although numerous studies on wheelchair seating systems have been conducted, it seems that the aspect of aforementioned problems can still be further improved. For reduce the risks of back pain, pressure ulcers, and decreased pulmonary function in wheelchair sitting posture. This study proposed a novel wheelchair seating system concept: the backward thoracic with upward femur support seating system. The purpose of this study was to evaluate the spinal angle, back muscle activation, interface pressure, pulmonary function, and subjective discomfort when using the backward thoracic with upward femur support seating system in the elderly population. Twenty elderly people were recruited for this study. the backward thoracic with upward femur support sitting (TF) was compared with the relaxed slouching sitting (RS), flat back support sitting (FB), prominent lumbar support sitting (PL), and backward thoracic support sitting (BT). Spinal angle (thoracic, lumbar, and pelvic angles), back muscle activation (maximal voluntary isometric contraction of the thoracic erector spinae at T9, iliocostalis lumborum pars thoracis, lumbar erector spinae, and lumbar multifidus on both sides), interface pressure (total contact area, average pressure, and peak pressure on backrest and seat), pulmonary function (forced vital capacity, forced expiratory volume in 1 second, and peak expiratory flow), and subjective discomfort (neck, shoulder, upper-back, mid-back, lower-back, upper-arm, lower-arm, buttock, thigh, and leg) were measured and compared. The results of spinal angle measurement: the TF showed relatively higher thoracic kyphosis and lumbar lordosis when compared with the RS, FB and PL, no significant difference when compared with the BT; and it also showed a relatively neutral pelvic tilt when compared with the RS and LP, no significant difference was observed when compared with the FB and BT. The results of back muscle activation measurement: the TF showed relatively higher back muscle activity when compared with RS and lower back muscle activity when compared with the FB and PL in all tested muscles, no significant differences when compared with the BT. The results of interface pressure measurement: the TF showed relatively higher total contact area, average pressure and peak pressure on backrest when compared with the other sitting postures; and the BT showed relatively lower average pressure and peak pressure on seat when compared with the other sitting postures; nevertheless, the TF showed relatively lower total contact area, average pressure, and peak pressure on the back part of seat and higher total contact area, average pressure, and peak pressure on the front part of seat when compared with the BT. The results of pulmonary function test: the TF showed relatively higher pulmonary function values when compared with the RS, FB, and PL in all tested parameters, no significant differences were observed when compared with the BT. The results of subjective discomfort evaluation: the TF showed relatively lower subjective discomfort in upper-back, mid-back, and lower-back when compared with the RS, FB, and PL, no significant difference when compared with the BT; and it also showed relatively lower subjective discomfort in buttock and higher subjective discomfort in thigh when compared with other sitting postures. The backward thoracic with upward femur support seating system concept was suggested because it maintains an increased lumbar lordosis with rather neutral pelvic tilt, decreased back muscle activation, diminished pressure on the ischial tuberosities, improved pulmonary function, and lessened subjective discomfort in back and buttock which may help maintains a better wheelchair sitting posture for reduce the risks of back pain, pressure ulcers, and pulmonary function decline. The achievements of this study contribute to the decision-making processes of wheelchair seating systems for consumers, clinicians, and manufacturers.

Abstract Following with the melioration of medical and engineering technology, its to attach importance to welfare and living quality of deformity; The ultimately purpose of rehabilitated medicine is to improve the functional development of deformities. In Taiwan, the cerebral palsy have often developmental delay, deformity, and functional disabilities resulting from abnormal muscle tone, reflex and impaired sensory system. Early intervention for C.P. initiating from 2 to 3 years old, who have received early rehabilitation treatment, seating and body supports with assistant technology as well as long-term training and education, has demonstrated to provied promising outcomes in significantly improved abnormal muscle tone, reflex, bodys coordination and balanced control. Unfortunately, there is lack of assistive technology service program to provide systematical clinical evaluation and prescription of specialized seating / positioning support systems for the neuromuscular impairment in Taiwan. In addition, the fields of rehabilitation technology/assistive devices are very new with little R&D. This project is to design specialized seating/positioning wheelchair for the cerebral palsied. The goal is to provide clinical effective seating supports for minimizing abnormal muscle tone and reflex, and to improve balance control, movement coordination and functional activities for the cerebral palsied. This project select 93 cerebral palsied, measuring the anthropometric data of optimized seating position. Using Multivariate Cluster Analysis to divide subjects into two clusrters, according to ages 2~8 and 9~26. Then using Univariate Regression Analysis to predict the range of anthropometric data in which two clusters. In order to target the modular dimension of the wheelchair main structure, therefore to follow the example of case numbers, to select in each division and to decide the standard dimension of seating anthropometric, at the same time to transfer variance into wheelchair’s main structure and to proceed conceptual design. The project using AutoCAD to draw wheelchair dimension plane and three-D conceptual drawing. Using spacilized CAD/CAM software Pro/Engineer to simulate actual wheelchair specification and to compute the center of gravity position and inertia tensor of wheelchair structure. The results of this project indicate that the center of gravity position locate upon the center axis of cross bar, underscoring the seating system. Conforming to safety designing condition; the next, in all direction of inertial tensor respect to wheelchair are greater than tensors of plane. It means that the motion of wheelchair will be slower when it turning around. In the other hand, it will be more laborions when family members moving wheelchair. In view of obvious variabilitiy between each cerebral palsy. The design of individual seating and positioning wheelchair must to be base on biomechanics, posture controling, neuropathology, human factor engineering, to investigate objective clinical evaluation, to provide effective personal deficient device. Final destination of this research are (1) Keeping normal posture control and bring to maximum regular function. Promoting the patient independent ability. (2) Providing clinical training and collecting the data auxiliaryequipment(3) Training engineers to design and manufacture seating and positioning body support. (4) Shifting technology to medical treatment system. Developing science and technology about auxiliaryequipment.

In addition to medical and rehabilitative treatments, seating/positioning is important to the individual with central nervous deficits, particularly for moderate or severe cerebral palsied (CP) children. It has been reported statistically in Taiwan that 0.6 to 5.9 per 1,000 children are affected by CP. Proper seating and body support devices are useful in normalized muscle tone, decreasing the influence of pathological reflex and improving body stability and movement for preventing deformities, developmental delays and functional disabilities from their life span. This research purpose was to develop a modular design of specialized wheelchair (WC) and support systems for effectively customized fitting the individual’ seating/positioning needs, and for minimizing the product design and manufacturing cost. More specifically, this research was to: (1) develop and establish modular parameters of mechanical structure, mechanics and components for the design specification of specialized WC and body support system; (2) apply CAD/CAM and finite element method (FEM) for mechanical design, stress and strain analysis of structural and mechanic components, and manufacturing of modular products. The modular design of seating/positioning devices has been motivated from wide variations of age, body sizes, neuromuscular impairments and functional support needs for the CP population. The seat width and depth, backrest height and leg length, seat and back angles, and other components’ dimensions in linear and angular ranges need to be considered in the design of specialized WCs with foldable, anti-tip and braking functions. The design of body supports needs consider the size, shape and fitting location of head and trunk supports, H hardness and safety belts, abductor and tray. In Stage I, the main structural parameters of WC’ seat width and depth, backrest height and legrest length for modular design specifications were determined from Average Linkage and K-means methods of multivariable cluster analysis on the anthropometrics data measured and collected from 140 CP cases (ranging from 2 to 25 years old). The dimensional ranges of other components and body support systems were also statically determined from the subject’ database for modular design specifications. In Stage II, SolidWorks packages with constructive solid geometry of pipe, beam and shell components and triangular elements of FEM with strength analyses of maximum shear stress criterion were used for CAD design and stress-strain analysis of the structural and mechanic components and modular parts of the special wheelchair with A6061T6 aluminum alloy tubing and plate. In Stage III, CAM was used for the manufacturing and dies molding and assembly of the modular design products. The R&D has completed 3 prototype design modules of large, medium and small folding and reclining WCs equipped with anti-tip and brake devices for safety, the dimensional options include: 25.4, 31.8 and 41.4cm for WC width; 18, 21, 26, 31, 36, 41, 47, 51 and 56cm for both WC depth and backrest height; 15, 21, 27, 33, 39 and 44cm for legrest length; 5, 8 and 12 for seat angle; 75, 85 and 95mm in radius curve for head support; 40 and 65mm height for trunk support; and 60, 80 and 100mm width for abductor. All parts and components are easily inserted and removed adjustably to fit each individual needs. A seating/positioning protocol has been developed for clinical evaluation, measuring, prescription and fitting of the specialized WC and body supports. Fifty cases with severe cerebral palsy have been prescribed and fitted with their appropriate WCs and supports with the assembly of developed modular components according to their individuals’ needs. This pilot field testing of clinical application has demonstrated that the modular design of wheelchair and seating/positioning supports is useful to provide effective mobility aids, normalized muscle tone, body alignment and postural control , and to improved the influence of reflex, body coordination, balanced and movement, and functional abilities. The『Modular Design』seems to be highly applicable to satisfy widely varied seating/positioning needs for the CP, SCI, Strokes, TBI, MD and MS. In addition, the design and manufacturing process can be achieved with significantly minimized the product cost for wheelchair industries. Further clinical studies for application outcomes need to be investigated.
