Bionic ankle-foot prosthesis normalizes walking gait for persons with leg amputation.
Over time, leg prostheses have improved in design, but have been incapable of actively adapting to different walking velocities in a manner comparable to a biological limb. People with a leg amputation using such commercially available passive-elastic prostheses require significantly more metabolic energy to walk at the same velocities, prefer to walk slower and have abnormal biomechanics compa...
متن کاملBionic Leg Prosthesis Emulates Biological Ankle Joint during Walking
Figure 1. The bionic prosthesis’ mass of 2.0 kg is equivalent to a biological foot and partial shank of an 80 kg person. The prosthesis includes a carbonfiber in-series leaf spring, unidirectional parallel leaf spring, and heel and forefoot leaf springs that provide elasticity. A series-elastic actuator performs negative and positive work. The actuator is comprised of a 200-Watt DC brushless mo...
متن کاملEvaluation of Gait Performance of a Hemipelvectomy Amputation Walking with a Canadian Prosthesis
Background. Hemipelvectomy amputation is a surgical procedure in which lower limb and a portion of pelvic are removed. There are a few studies in the literature regarding the performance of subjects with hip disarticulation during walking. However, there is no study on gait analysis of hemipelvectomy subject. Therefore, the aim of this paper was to evaluate the gait and stability of subject wit...
متن کاملProsthesis use in persons with lower- and upper-limb amputation.
This study identified clinical (e.g., etiology) and demographic factors related to prosthesis use in persons with upper- and lower-limb amputation (ULA and LLA, respectively) and the effect of phantom limb pain (PLP) and residual limb pain (RLP) on prosthesis use. A total of 752 respondents with LLA and 107 respondents with ULA completed surveys. Factors related to greater use (hours per day) f...
متن کاملGait changes with walking devices in persons with Parkinson's disease.
PURPOSE To study immediate gait changes in persons with PD when walking with different assistive walking devices. METHODS Ten individuals with idiopathic PD participated in the study. Gait parameters were recorded while walking with a cane and a wheeled walker, and were compared to a free walk without a walking device. RESULTS Persons with PD walked with slower gait speed when using a cane ...
