RELATIONSHIP OF ISOKINETIC HIP ADDUCTOR STRENGTH WITH STATIC AND DYNAMIC BALANCE

Safa Anwar* Rizwan Khan and Nigar Shikalgar

ABSTRACT

Objective: Balance is considered an important aspect of performance which is achieved by a complex process involving the musculoskeletal and neurological systems. Hip adductor muscles play an important role in movement and stability at the hip joint. Isokinetic dynamometers are extensively used to evaluate muscular strength of leg muscles at various angular velocities.The difference in dominant lower limb (DL) and non-dominant lower limb (NDL) muscle strength will predict how balance could be affected and it will significantly help physical therapists to set goals in rehabilitation programs of patient with lower limb muscle injuries with impaired balance. Patients and Methods: 50 males subjects between the age group 18-25 years were recruited. Hip adductor muscle strength was measured by isokinetic dynamometer, dynamic balance was assessed by Y-balance test and static balance was assessed by single leg standing test. Results: Mean characteristics of the subjects were age (21.40±1.75) and BMI (21.3±1.77). Peak torque of adductor (Ptad) muscle in NDL was 56.10±20 whereas Peak torque in DL was 64.12±18.55. Pearson correlation coefficient between Ptad and dynamic balance was r=0.44 and between Ptad and static balance r=0.48, which suggest moderate positive correlation in both scenarios. Conclusion: Hip adductors are majorly responsible for our basic activities like in walking, sitting to stand washing or simple stair climbing. Therefore, knowledge about hip adductor strength and its relation to balance should be well assessed by the therapist to prevent injuries and design a treatment plan.
