Conditions
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.

Interventions
Patients underwent an isokinetic strength training program with 3 sessions per week during five weeks. Program consists of excentric contraction of knee flexor and extensor muscles (4 x 7 Contractions at 30°/s) and concentric contractions at maximal speed where patients can perform 40% of his maximal isometric torque for knee flexor and extensor muscles (2x10 for knee flexors and 2x10 for knee extensors)
