Abstract:
Objective To explore the effect of intensive hip adductor isometric strength training on the balance ability of functional ankle joint instability. Methods From November, 2019 to January, 2020, 18 college students with functional ankle instability were recruited from a university in Shenzhen and randomly divided into control group (n = 9) and experimental group (n = 9). Both groups received ankle stability training, and the experimental group received isometric muscle strength training of hip adductor in addition, one hour a time, three times a week, for four weeks. The Cumberland Ankle Instability Assessment Questionnaire (CAIT), Y Balance Test (YBT), Balance-check balance equipment and Back-check hip adductor maximum isometric strength test were performed before and after training. Results After training, the scores of CAIT, YBT and balance-check increased in both groups (t > 2.540, P < 0.05); the strength of adductor hip muscle significantly increased in the experimental group (t = 8.485, P < 0.001). The d-value of CAIT score, YBT distance, the score of Balance-check, and the strength of adductor hip muscle were more in the experimental group than in the control group (t > 2.168, P < 0.05); the d-value of the average rotation speed, the maximum rotation speed and the balance level were less in the experimental group than in the control group (t > 2.804, P < 0.05). Conclusion Hip adductor isometric muscle strength training may promote the recovery of the balance after functional ankle instability.
