Caractérisation de la coordination motrice des membres inférieurs lors de la marche des patients hémiparétiques

Abstract : Paresis, muscle hyperactivity and soft tissue retraction are the main mechanisms responsible for the gait disturbance in hemiparesis. In the rehabilitation management of hemiparetic patients, clinicians try to determine the responsibility of each mechanism, and to quantify the impact of treatments on movement organization and gait efficiency. Inter-segmental coordination analysis, using measurement of the continuous relative phase in the sagittal plan, can assist in reaching these objectives. The amount of dephasing between lower limb segments, in each phase of the gait cycle, sheds light on the coordination pattern. Relevant parameters of the inter-segmental continuous relative phase may reveal specific information such as the predominance of neurological and orthopedic factors implied in the kinematic deficits, the impact of various gait rehabilitation conditions, or treatment-related benefits. This analysis, complementary to routine clinical examination, may also disclose specific motor deficits in the paretic lower limb, and compensatory strategies at work in the non-paretic lower limb. The findings reported in this thesis may encourage rehabilitation clinicians to carefully study coordination patterns, which may help define optimized treatments to lessen gait impairment in spastic paresis.
