Background: Muscle weakness in the lower limbs has adverse effects on walking performance and functional mobility in patients with stroke. Therefore, interventions aiming to improve muscle strength post stroke are considered crucial part of stroke rehabilitation.

Objective: To determine the effectiveness of isokinetic strength training for knee and ankle muscles of the affected side on muscle strength, gait and functional mobility in chronic stroke.

Materials and Methods: Thirty patients with stroke of both sexes (46-62 years) shared in this study. They were randomly assigned into two equal groups; experimental and control groups. Patients in the experimental group received a traditional physical therapy program in addition to isokinetic training for knee and ankle muscles in the affected side. Those in the control group received only the traditional physical therapy. Treatment was provided three times per week for eight successive weeks. The participants received pre and post-treatment assessments for the peak torque of the trained muscles, gait parameters and functional mobility as measured by the Timed Up and Go (TUG) test.

Results: Patients in both groups showed significant improvement post treatment in peak torque of knee and ankle muscles, gait parameters and TUG test (p<0.05). Additionally, after the intervention, between-group comparison revealed significant difference for peak torque of both knee and ankle muscles (p<0.05), walk speed (t=2.44, p=0.02), gait cycle time (t=-3.43, p=0.002), single limb support (t=3.58, p=0.001) and TUG test (t=-3.45, p=0.002) in favor of the experimental group.

Conclusion: Isokinetic strength training of the affected lower limb muscles in conjunction with proper physical therapy exercise program is effective in improving muscle strength, walking performance and functional mobility in patients with stroke.
