Powered prosthetic legs could significantly improve mobility for lower-limb amputees, but the performance and clinical viability of these devices are currently limited by complex control systems that independently control different joints and time periods of the gait cycle. Recent efforts have been made to address these challenges with a unifying control model used by recent bipedal robots, in ...

1 Motivation Walking with traditional passive lower-limb prostheses requires additional muscular effort and increased metabolic consumption (1.3-2.5 times the energy expended by a healthy person [1]). This supplementary effort cannot be sustained by many geriatric and dysvascular amputees (the majority of the amputee population [2]) for more than few steps, resulting in a partial or total reduc...

Abstract—The upper limb amputation exerts a significant burden on the amputee, limiting their ability to perform everyday activities, and degrading quality of life. Amputee patients’ life can be improved if they have natural control over prosthetic hands. Among biological signals, most commonly used predict motor intentions, surface electromyography (sEMG), axial acceleration sensor signals are...

introduction: estimation of stature is one of the most important fields in forensic medicine. also it is of particular interest to anthropologists and anatomist. our aim was to investigate the relationship between stature and the length of lower limb and foot to derive a regression formula for estimating the stature. methods: three anthropometric measurements stature, lower limb length (lll) an...

elephantiasis nostras verrucosa (env) is a rare condition in which hyperkeratosis, fibrosis and disfiguration of dermis occurs. it is caused mostly by non infectious diseases such as surgery, trauma, tumors, and venous obstructions. to our knowledge there is not any case report of env in middle east region. in this patient, env caused by trauma and patient presented with enlargement of right lo...

The following brief report describes the experiences of a hand and arm amputee following the administration of the Harvard Group Scale of Hypnotic Susceptibility, Form A (HGSHS:A) of Shor and Orne, 1962. The participant passed two of the three motor items involving his missing limb. This report discusses the results of a postsession interview regarding our participant's experiences during hypno...

The value of fitting adult upper limb amputees with electrically powered prostheses is assessed. In a series of 164 amputees, complete or useful acceptance of an electrically powered prosthesis was recorded in 80% of below-elbow amputees, 69% of above-elbow amputees and 72% of high level amputees. Patients expressed satisfaction with the combination of comfort, cosmesis and function. Results in...

Phantom limb pain in amputee patients is not well defined in the literature. Also there is still no clear information on the definition and treatment of phantom radicular pain, in which amputee patients also have radicular pain. This phenomenon, called phantom radiculitis or phantom radiculopathy, has been described in a limited number of cases. If a pathological condition to cause radicular pa...

We provide a summary of professionals’ opinions on the most important factors in the successful use of an upper-limb prosthesis. This summary allows designers and researchers to ensure they are pursuing the most needed areas of improvement and allows patients and professionals to compare their opinions. Comfort, specifically socket-interface comfort, was considered most important for a unilater...

The goal of this study was to gather the opinions of prosthetics experts on the most important factors for the successful use of upper-limb (UL) prostheses, compare them with those of prosthesis users, and ultimately direct research efforts in this field. UL prosthetics experts were asked to compare the importance of the comfort, function, and cosmesis of a prosthetic device for a transhumeral ...
