Investigation of the relationship between lower extremity muscle strength and hip functions in adult individuals with developmental hip dysplasia
Abstract
Purpose: Varying degrees of muscle weakness are observed in muscles of individuals with developmental dysplasia around the hip. One of the important parameters that determine functionality for hip joint is the basic movements during daily living activities and requires hip muscles strength. The aim of this study was to investigate whether lower extremity muscle strength is associated with hip functions in developmental dysplasia subjects.
Method: Twenty-six female patients (mean age 40.46±2.28 years (range, 20-60 years)) with the developmental dysplasia of hip who haven’t undergone total hip arthroplasty were included. Isometric muscle strength of hip flexor, extensor, abductor, adductor, internal rotator, external rotator, quadriceps femoris and hamstring muscles (medial-lateral) was evaluated with hand dynamometer and hip functions was evaluated with Harris Hip Score.
Results: There was a significant positive moderate correlation between Harris Hip Score and hip flexors, extensors, abductors, adductors, and lateral hamstring (biceps femoris) muscle strength (p<0.05), no relationship was found with internal and external rotators, quadriceps femoris and medial hamstrings (p>0.05).
Conclusion: There is a close relationship between hip muscle strength and hip function in individuals with developmental dysplasia of hip. This relationship includes hip flexors, abductors, adductors, lateral hamstrings and hip extensors, and as these muscles’ strength decreases, hip function decreases. In contrast, hip rotators, quadriceps and medial hamstrings strength are not related to hip function. Therefore, in order to achieve a good functional level in these patients, hip muscle strength should be good and strengthening exercises should be given importance in the treatment.
