Overview

Amputation is a life-altering event with an immediate and obvious effect on daily life activities and quality of life. Asymmetrical movements of the lower limbs and compensatory strategies during walking are associated with an elevated risk for developing deleterious secondary health conditions. It is well established that therapeutic gait training methods are effective in reducing spatiotemporal gait deviations and improving functional mobility. However, the littérature does not clearly indicate the best time to perform a gait training or which gait parameters predict it. The main aim of this study is to determinate the walking strategies of lower limb amputees in several locomotion tasks on daily life. Then, the investigators study the evolution of these walking strategies after a gait training and over time.

Quantified gait analyses are included in the practice for consultations to monitor orthopaedic devices, and are specific to the study for the rehabilitation stay (V2 and V3). The subjects in the control group will be recruited from among the carers of patients undergoing rehabilitation and from among volunteers recruited by means of posters in the establishments of the HOPALE Foundation in Berck. Once the eligibility criteria have been checked, a quantified gait analysis and functional tests will be carried out: the 6-minute walk test (T6M) and the Time Up and Go test (TUG). They will complete a single visit lasting approximately 1 hour and 30 minutes.
