Effects of Isokinetic Strength Training of Knee Flexor and Extensor Muscles on Walking in Hemiparetic Patients With Knee Extension Thrust

What this Trial Is About

Researchers are evaluating the effects of isokinetic strength training on walking performance in hemiparetic patients who experience knee extension thrust during walking. This study focuses on patients who have had a hemorrhagic or ischemic stroke, either in the subacute stage (less than 6 months) or chronic stage (more than 6 months). The study uses a single case experimental design with multiple baselines to test the impact of the intervention with a small group of 12 patients. Participants will continue their usual rehabilitation program at a day hospital, which includes physiotherapy, physical activity, and if needed, occupational and speech therapy. After a randomized baseline period of 3, 4, or 5 weeks, isokinetic strength training will be added to the rehabilitation. The training involves three sessions per week over five weeks, focusing on eccentric and concentric contractions of the knee flexor and extensor muscles at specific speeds and intensities. During the study, researchers will measure spontaneous walking speed and various walking and strength assessments over 25 weeks. These include tests such as extensor thrust analysis, walking speed, stair climbing, inclined plane, six-minute walk, sit-to-stand, fatigue, and strength evaluations. Participants will be monitored through repeated assessments, and their progress will be analyzed using specific statistics and visual methods to understand the training's impact.
