Background and Objectives: Lower extremity injuries are commonly due to impaired   balance. The best to assess lower extremity alignment is the Quadriceps angle (QA), it says the   important variable and because it represents quadriceps muscles vector direction in frontal  plane. The purpose of this study is to find a correlation between quadriceps angle on static  and dynamic balance measures. Methodology: Ethical clearance was obtained from institutional ethical committee.  Subjects fulfilling the inclusion and exclusion criteria were included. Informed consent form  was taken from each of the subject prior to the treatment. A sample of 95 subjects recruited  between 60 years and above. These participants were recruited using purposive sampling. This Correlation analytical study consists of Timed Up and Go Test And Berg Balance Scale  for assessing functional mobility and Balance(Static and Dynamic) respectively and data was  analysed using the statistical package SPSS 22.0 (SPSS Inc.., Chicago, IL) at p<0.05.
Result: The result of research suggests that there is a Statistically significant with moderate   positive correlation (p=0.002*) observed between Q-angle with TUG (which measure dynamic   balance). There is significantly weak positive (p=0.095) correlation observed between Q-angle  with BBSS values (which measures both static and dynamic balance). Conclusion: In this study, the effect of Q angle has moderately positive correlation  with dynamic balance. A Q angle is weakly correlated with the static balance. That means  quadriceps angle plays an important role in predicting injuries of lower extremity. This  makes an important diagnostic tool during assessment of an individual, especially in Geriatric population
