Abstract

Background: Genu recurvatum is a knee hyperextension deformity associated with altered biomechanics and impaired dynamic balance. Young women are more prone to this condition due to ligamentous laxity and reduced hamstring muscle strength. Aim: The aim of the study was to evaluate the correlation of knee hyperextension with hamstring muscle strength and dynamic balance in young women. Settings and Design: A pilot study was carried out among undergraduate college women in Southern Karnataka. Methods and Material: Young women aged 18-25 years recruited through convenience sampling. Knee Hyperextension, Hamstring muscle strength and dynamic balance were evaluated using the Kinovea software, Handheld Dynamometer, and Y Balance test, respectively. Statistical Analysis Used: Statistical analysis were performed using SPSS version 29.0. Descriptive statistics and Karl Pearson's correlation coefficient were applied. Statistical significance was defined as a p<0.05. Results: Correlation analysis revealed a significant strong negative association between hamstring muscle strength and knee hyperextension on both the right (r =−0.865, p<0.001) and left (r=−0.881, p<0.001) sides. Dynamic balance showed a significant strong negative correlation with knee hyperextension on the right (r=−0.902, p<0.001) and left (r=−0.919, p<0.001), indicating that greater hamstring muscle strength and better dynamic balance were linked to reduced knee hyperextension.
