Clinical Trial Summary

Lower limb amputation (LLA) is a major public health problem, with significant human and financial impact. Epidemiological data remain scarce in the literature. The primary objective of the equipment of lower limb amputees is to give a walking ability and autonomy that are closest to the previous state before the amputation. About microprocessor-controlled prosthetic knees (MPKs), there are currently three in France who benefit from support by health insurance : 3C100 knee C-leg (Otto Bock HealthCare, Duderstadt, Germany), the Rheo Knee (Ossur, Reykjavik, Iceland) and knee HYBRID 1P360 (Proteor, Saint Apollinaire, France). These prostheses have the common feature of being equipped with a single-axis prosthetic knee, controlled by a microprocessor, wich allows to adapt instantly to the user's walking speed changes. They are indicated in the proximal amputations of the lower limbs from knee disarticulation included. Their prescription can only be made by a doctor of Physical Medicine and Rehabilitation. These prostheses are subject to four criteria attribution and reimbursement by the List of Products and Services Refundable (LPPR = Liste des Produits et Prestations Remboursables). This criteria are the ability to: have a walking speed greater than or equal to 4 km/h, walk 2km continuous, descend an inclined slop of 15% and to walk down the stairs step by step. These criteria must be validated after a minimum trial period of 15 days.

These attribution criteria raise the question today of how they are measured, no recommendation defining this procedure. While many standardized assessment tests of different gait parameters are available and used in clinical research, the attribution criteria are not being built in reference to these tests.

The overall objective of the study is to evaluate the diagnostic value of two simple clinical tests, the 2 and 6 minutes walk tests, to assess functional performance in patients with transfemoral amputees with a microprocessor-controlled Prosthetic Knees (MPKs).
