Amputation is a common late stage sequel of peripheral vascular disease and diabetes or accidental trauma, civil unrest landmines. The functional impairments affect many facets life including but not limited to: Mobility; activities daily living; body image sexuality. Classification, measurement comparison the consequences amputations has been impeded by availability internationally, multiculturally standardized instruments in amputee setting. introduction International Classification...
Cyclists with unilateral transtibial amputation (CTA) provide a unique model to study integration of the neuromuscular and bicycle systems while having option modify this via properties prosthesis. This included eight CTA nine intact cyclists. The cyclists pedaled on stationary instrumented force pedals. group stiff or flexible prosthetic foot during simulated time trial low difficulty condition. During condition, pedaling resulted in work asymmetries 11.4% 30.5%, displayed 11.1% 21.7%, 4.3%...
People with amputations may find cycling advantageous for exercise, transportation and rehabilitation. The reciprocal nature of stationary also makes it a viable model research in motor control because the body is supported by saddle allowing researcher to focus on cyclic movement legs without confounding variable balance. purpose this article provide an overview task intact cyclists relate information understanding challenges faced transtibial (CTA). Ongoing into biomechanics CTAs will be...
This article presents recent results in the development of skin and bone integrated pylon (SBIP) intended for direct skeletal attachment limb prostheses. In our previous studies porous SBIP-1 SBIP-2 prototypes, bond site between pylons residuum did not show inflammation characteristically observed when solid are used. At same time, porosity diminished strength pylon. To find a reasonable balance biological conductivity pylon, we developed mathematical model composite permeable structure. A...
The mirror neuron system has been attributed with increased activation in motor-related cortical areas upon viewing of another's actions. Recent work suggests that limb movements are similar and dissimilar appearance to the viewer equivalently activate system. It is unclear if this result can be observed action encoding amputees who use prosthetic devices. Intact subjects upper extremity amputee prosthesis users were recruited view video demonstrations tools being used by an intact actor a...
Background. Previous studies have demonstrated improved neurobehavioral outcomes when prosthesis users learn task-specific behaviors by imitating movements of (matched limb) compared with intact limbs (mismatched limb). Objective. This study is the first to use a unique combination neurophysiological and task performance methods investigate prosthetic device training strategies from cognitive motor control perspective. Intact nonamputated (NAPUs) donned specially adapted devices simulate...
Prior work in amputees and partial limb immobilization have shown improved neural behavioral outcomes using their residual with prosthesis when undergoing observation-based training a prosthesis-using actor compared to an intact limb. It was posited that these improvements are due alignment of user the actor. may be affected by visual angles allow emphasis critical joint actions which promote changes. The purpose this study examine how viewing perspective effects adaptation naïve device...
Purpose: The objectives of this study were to compare three á priori alignment methods and evaluate them based on initial gait quality further changes required optimize gait. Á is requisite for monolimbs, transtibial prostheses in which the socket pylon are made from one piece plastic, because monolimbs have no adjustability. Method: investigated traditional bench (TRAD), vertical axis (VAA) anatomical (ABA). Endoskeletal components utilized study, rather than so that could be experimentally...
Cutaneous feedback from feet is involved in regulation of muscle activity during locomotion, and the lack this results motor deficits. We tested hypothesis that locomotor changes caused by local unilateral anesthesia paw pads cat could be reduced/reversed electrical stimulation cutaneous proprioceptive afferents distal tibial nerve stance. Several split-belt conditions were investigated four adult female cats. In addition, we effects similar on overground walking one male had a transtibial,...
