Filter by:The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by nonbreathable and non-thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to passively conduct heat from the skin using thermally conductive elastomers. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.
The comfort and fit of the residual limb within a prosthetic socket are of primary concern for many amputees. The residual limb is typically covered by non-breathable and non- thermally conductive materials that can create a warm and ultimately moist environment. The investigators have developed a silicone liner approach to remove sweat from the skin and out of the socket and to passively conduct heat from the skin using thermally conductive elastomers. This liner has been developed to work alongside a thermo-electric cooling (TEC)-based module called the Intrasocket Cooling Element (ICE) developed in a parallel project by Vivonics, Inc. and Liberating Technologies, Inc. The ICE device can be embedded into the prosthesis in order to cool the residual limb. A technology that can provide thermal control while retaining adequate suspension, weight, and other prosthetic characteristics would benefit many prosthesis wearers.
This study was performed to determine the presence of any difference between Pin Suspension (PS) and Active Vacuum Suspension (AVS) on walking capacity, functional mobility, weight bearing in the prosthetic side, prosthetic satisfaction and body image were evaluated. Nine patients who don't have an obstacle to both socket applications in terms of stump height, type and edema were evaluated in this study. Both suspension systems were administered to the patients included in the study. First, amputees have used PS for 3 months following alignment of the prosthesis and training period. Then again they used AVS for 3 months following alignment of the prosthesis and training period. For each system, after adapting prosthesis 'LASAR posture' was used to evaluate weight bearing on the prosthetic side, '6 Minute Walk Test' for walking capacity, 'Time Up and Go' test for functional mobility, 'Prosthetic Satisfaction Index' for prosthetic satisfaction and 'Amputee Body Image Scale' for body. There were statistically significant difference between PS and AVS in terms of prosthetic side weight bearing percentage, walking capacity, functional mobility and prosthetic satisfaction (p<0.05), in favor of AVS. There were not statistically significant difference between the body image scores (p>0.05). From the view of function and prosthetic satisfaction, AVS was found to be more effective in transtibial amputees. It is believed that our study will be a guide to the future studies including higher number of amputees, different amputation levels and different suspension systems.
Lower extremity amputation causes rapid changes in musculoskeletal system. With the effect of these changes, the energy requirement for prosthetic ambulance is much higher than normal ambulance. Although methods such as the reduction of the segmental load of the prosthesis and the preference of the different prosthetic components for energy expenditure have been emphasized, the effect of exercise types has not been investigated in our knowledge. Therefore, the aim of the current study is to investigate the effect of spinal (Core) stabilization exercises on energy expenditure in combination with the classical physiotherapy program in patients with unilateral transtibial amputation. Individuals with transtibial amputation included in the study will be randomly divided into two groups. In group 1, basic exercises related to amputation will be applied for 8 weeks and in group 2 basic exercises with spinal stabilization exercises will be applied to the individuals. At the beginning and at the end of the exercise intervention, energy expenditure and exercise capacity will be evaluated by a portable exercise test device during '6 Minutes Step Test'; fatigue assessment will be done before and after 6 Minutes Step Test with 'Modified Borg Scale'; the strength of deep spinal muscles will be evaluated with 'Stabilizer'; dynamic balance and functional mobility will be evaluated by 'Timed Up & Go' Test; and the effect of the prosthesis on mobility will be evaluated by the sub-scale 'Mobility' of 'Prosthetic Evaluation Questionnaire'.

The Department of Veterans Affairs (VA) provides wheelchairs to about 42,000 Veterans with SCI and more than 40,000 Veterans with amputated limbs (AL). Despite VA's efforts to remove financial and other barriers to the provision of wheelchairs to all Veterans who need them, preliminary evidence suggests that disparities exist in the quality of wheelchairs prescribed to racial minorities and low income Veterans with SCI or AL. The proposed project will provide important information to the VA about the quality and equity of wheelchairs provided to Veterans with SCI or AL, and it will identify the patient and provider factors associated with wheelchair provision. Because Veterans with SCI and AL are considered special disability populations, identifying and understanding these factors is a critical first step to developing interventions to increase the quality and equity of wheelchairs provided to all disabled Veterans.
