Effect of partial weight bearing program on functional ability and quadriceps muscle performance in hemophilic knee arthritis

Abstract

Recurrent joint bleeding in persons with hemophilia is known to lead to joint damage associated with pain, loss of range of motion and function. The researcher was motivated by the essence of the importance of partial weight bearing program in rehabilitation of lower limb conditions and the lack of literatures regarding these exercises in rehabilitation of hemophilic knee arthritis. The purpose of this study was to investigate the effect of partial weight bearing program on functional ability and quadriceps muscle strength in children with hemophilic knee arthritis. Thirty patients had participated in this study; with age ranged from eight to twelve years. They were randomly assigned into two equal groups. Patients were evaluated pre and post treatment for their functional walking, and isometric strength of quadriceps. The control group (group A) received quadriceps training exercise program, while the study group (group B) received a program of partial weight bearing added to the same exercise program of group A. Treatment was given 3 times/week, every other day, for six consecutive weeks. The results of the study revealed that both groups demonstrated a significant increase in function, as measured by the six minute walking test (6MWT), although there was no significant difference between both groups concerning improvement of function. Quadriceps isometric muscle strength was significantly improved in both groups, in favor of group B (study group). To conclude the partial weight bearing program may be used as a therapeutic intervention for improving functional ability, and muscle performance in children with hemophilic knee arthritis.
