Abstract
Background and objective: Although the main goal in Perthes disease treatment is to increase the contact area between the femoral head and acetabulum and also to reduce the pressure applied on the hip joint, but no treatment was successful in this field. It seems that not any study has yet investigated the effect of orthoses on joint reaction force in Perthes disease. The purpose of this study was to assess the hip joint reaction force in Perthes disease with and without the use of Scottish rite orthosis.
Methods: The research is a case series study. In this study, among 10 patients suffering from perthes two seven-years-old boys with Perthes disease in the right hip joint were selected. These boys had no history of orthopedic and other structural problems. They were asked to walk in the lab space with and without Scottish rite orthosis. Open SIMM software for evaluation of joint reaction force was used in both situations. Using paired t-test, the difference between kinetic and kinematic parameters for each individual was analyzed.
Result: The findings of this study indicated that ground reaction force was increased during the use of orthotics, although it seems that joint reaction force is reduced with the use of orthotics (P= 0.05). Use of orthoses can affect the kinematic of hip joint and pelvic.
Conclusion: Since the joint reaction force is one of the most important parameters that affected the joint destruction and deformity, it can be said that the use of orthosis can affect the final joint deformity. Thus, it is recommended that further research be carried out on more cases.
