Sensory substitution of elbow proprioception to improve myoelectric control of upper limb prosthesis: experiment on healthy subjects and amputees.

Background: Current myoelectric prostheses lack proprioceptive information and rely on vision for their control. Sensory substitution is increasingly developed with non-invasive vibrotactile or electrotactile feedback, but most systems are designed for grasping or object discriminations, and few were tested for online control in amputees. The objective of this work was evaluate the effect of a novel vibrotactile feedback on the accuracy of myoelectric control of a virtual elbow by healthy subjects and participants with an upper-limb amputation at humeral level.

Impact of C-LEG on mobility, satisfaction and quality of life in a multicenter cohort of femoral amputees.

Background: In some countries, the microprocessor-controlled C-LEG knee joint is reimbursed by the national health insurance for transfemoral amputees under certain conditions. However, whether users really benefit from such a technology in their daily life is unknown.

Objective: To observe the performance of active C-LEG users in terms of locomotor ability and activities, satisfaction and quality of life after 6 months of wearing the prosthesis in real-life conditions.

Mobility and satisfaction with a microprocessor-controlled knee in moderately active amputees: A multi-centric randomized crossover trial.

Objective: Microprocessor-controlled knees are generally prescribed and reimbursed for active amputees. Recent studies suggested that this technology could be useful for amputees with moderate activity level. We compared the efficiency of a microprocessor-controlled knee (MPK, Kenevo, Otto Bock) and non-MPKs (NMPKs) in these indications.
