Normative Values Of Strength Of Hip Adductors In Runners Assessed By Using Pressure Biofeedback Unit

Hip Adductors Strength And Pressure Biofeedback Unit

Abstract

Abstract: Background: Muscle strength measurement is a key component of physiotherapists’ assessment and is frequently used as an outcome measure. A pressure biofeedback unit can be potentially used as a tool to assess hip isometric muscle strength. Objectives: This study was designed to establish normative adductor squeeze test (AST) values in runners and investigate strength of adductor muscles during the performance of the thigh adductor squeeze test at 0°, 45°, and 90° of hip flexion. Material And Methods: A total of 51 healthy runners aged 23-27 years participated. Each participant performed 3 trials of the thigh adductor squeeze test in the three positions at 0°, 45°, and 90° of hip flexion. Pressure biofeedback unit was used to assess the strength of hip adductor muscles. Strength of the adductors was measured as the maximum pressure that was achieved by the subject from 10 mm Hg. Result: Mean strength is 103.05 ± 23.05 mmHg at 0° hip flexion, 141.03 ± 24.31 mmHg at 45° hip flexion and 134.86 ± 22.83 mmHg at 90° hip flexion position. Conclusion: The results of the present study suggest that the 45° of hip flexion test position is the optimal thigh adductor squeeze test position. [Mehta K Natl J Integr Res Med, 2019; 10(6):6-10]
