relationship between BMI and Idiopathic Knee pain in Middle Aged Adults

Null Hypothesis (H0) In middle-aged people, there is no significant correlation between the severity of idiopathic knee pain and body mass index (BMI) Alternative Hypothesis (H1) In middle-aged adults, idiopathic knee pain severity is significantly correlated with Body Mass Index (BMI), with higher BMI being linked to more severe pain. The data were collected from 64 middle-aged adults (40–60 years) with idiopathic knee pain using BMI measurements, the Visual Analogue Scale (VAS), and the Lower Extremity Functional Scale (LEFS).

The findings demonstrated a significant positive relationship between BMI and pain intensity, while a significant negative relationship was observed between BMI and functional performance. Participants with higher BMI reported greater knee pain and poorer lower-extremity function, indicating that excess body weight may contribute to both increased pain severity and reduced functional capacity. These results can be used to support the importance of weight management and physiotherapy interventions in individuals with idiopathic knee pain.
