Abstract
Purpose. To detect effect of hip abductors against quadriceps exercises on quadriceps isometric strength in Knee OA individuals.
Methods. Seventy patients with bilateral knee OA were recruited , ages ranged between 50-70 years. They were randomized into equal groups; hip abductors strengthening exercises (HAS) group and knee extensors strengthening (KES) group. Both groups received hamstring stretch. Duration was 6 weeks (2 sessions per week). Baseline and 6 weeks assessments of quadriceps isometric strength were done using hand held dynamometer.
Results. there wasn’t any statistical significant difference between the two groups.
Conclusion. Both forms of exercises have the same effect on quadriceps isometric strength.
