Correlation Between Body Mass Index, Navicular Drop and Q-Angle in Different Position Among College Students - Correlation Study

Abstract

INTRODUCTION: The Q-Angle is an index of the vector of the combined pull of the knee extensor mechanisms and the patellar tendon. The Navicular Drop Test, is one of the clinical tests most commonly used to study Medial longitudinal arch. It has been found that the different weight of individual may alter the Q-angle. AIM: To find out the correlation between BMI, Q-Angle and Navicular Drop in different position in college going student. METHODOLOGY: The participants were taken from Apollo Institute of Physiotherapy and informed written consent was taken from all the participants. Body Mass Index was calculated by standard formula [weight(kg.)/height2(meter)]. Navicular Drop was measure by using a scale and card method and Q-Angle was measure in standing and supine position by using Standard Goniometer. RESULT: The study showed a weak correlation of right Q-Angle supine with right Navicular Drop (r= 0.14, p=0.31) and no correlation of right Q-Angle standing with right Navicular Drop (r=0.02, p=0.85). Also, there is no correlation of left Q-Angle supine with left Navicular Drop (r= 0.08, p=0.54) and weak correlation of left Q-Angle standing with left Navicular Drop (r=0.11, p=0.43). There is weak correlation between BMI with Q-Angle (in different positions) and Navicular Drop. CONCLUSION: Thus, this study concluded that there is weak correlation between BMI, Q-Angle and Navicular Drop. Also suggested that change in the position may alter Q-Angle and Navicular Drop.
