Background: Quadricep muscles of the leg is of highest clinical significance weakness in this muscle are common in diabetic patients and in obese persons quadriceps had role in our daily activity which helps in knee extension and weight bearing. Objective(s): To find the association of the quadriceps strength with BMI in diabetic patients. Methodology: A cross sectional study was done on a population basis. A total of 366 patients of diabetes were included in this study. Data were collected through non-probability convenient sampling technique. A proforma was used to get demographic data including Name, Age, Marital status and their body mass index was also calculated quadriceps strength was measured through by using Manual muscle testing (MMT). Results: out of 366 total participants 81(22.1%) were males and 285(77.9%) were females. Their mean age was 46.78(standard deviation =11.67270 and the mean BMI was 2.7077 (standard deviation = 5.1012) quadriceps strength and BMI in diabetic patients had a strong direct and statistically significant association, age and BMI had a positive and statistically significant association with the quadriceps strength in diabetic patients with a (p value .311) Conclusion(s):It was concluded that BMI had a great impact on the strength of quadriceps in diabetic patients this study demonstrated that BMI is strongly related with decreasing quads strength in diabetic patients
