Conditions
Gait Disorder
Hemiparesis/Hemiplegia (One Sided Weakness/Paralysis)
Interventions
Behavioral: isokinetic strength training of knee extensor and flexor muscles
Registration Number
NCT05887440
Lead Sponsor
Rennes University Hospital
Brief Summary

The purpose of this study is to assess the impact of an isokinetic strength training of knee flexor and extensor muscles on walking performance in hemiparetic patients with knee extension thrust.

Detailed Description

The study will be interventional single case experimental design (SCED) with multiple baseline design. SCED are experimental designs aiming at testing the effect of an intervention using a small number of patients using repeated measurements, sequential and randomized introduction of an intervention and method-specific data analysis, including visual analysis and specific statistics.

During baseline, patients will have a rehabilitation program in day hospital (4 days per week) with physiotherapy and physical activity and if necessary occupational and speech therapy. Isokinetic strength training will be added to this conventionnal rehabilitation program and will begin after 3, 4 or 5 weeks of baseline according to randomization

12 patients will be included in this study (6 patients in subacute stage and 6 in chronic stage ).
