Background: The lower limb muscle strength is an important determinant of physical function in healthy individuals. However the quadriceps muscle strength can be assessed traditionally by using weight cuff. By using the traditional method the exceptional level is high. So to reduce this load this study was aimed to correlate the weight cuff and hand held dynamometer for assessing the strength of quadriceps muscles.

Methods: 100 subjects was assessed for the quadriceps muscle strength that is knee extension using hand held dynamometer and weight cuff. For one day the assessment of hand held dynamometer was done and the next day weight cuff assessment was done.

Result: Infra correlation and regression exhibited no statically significant correlation of hand held dynamometer and weight for assessing strength of quadriceps muscle. But was clinically Signiant and correlating with the mean for weight cuff (93.4) hand held dynamometer mean was (3.48) Best fit value for weight cuff was (3.7) and for hand held dynamometer was (-16.7) R= 0.47. Which means the study is not statistically significant since the regression.

Conclusion: There is no statically significant correlation between hand held dynamometer and weight cuff for assessing the strength of quadriceps muscle. But the hand held dynamometer and weight are clinically significant and correlating.
