Influence of Overweight and Obesity on Pelvic Tilt, Q-Angle and Foot Posture in Both Genders

Abstract

Background: Normal movement pattern and its relationship with various segments of the body create a kinetic chain for performing certain activities. The abnormal patterns of movement may precipitate risk of injuries at any segmentleg from the pelvis to the foot [1-3]. Obesity has been marked as risk factor for postural instability. The mechanism of altering body geometry due to excessive deposition of body fat at certain areas like abdomen and hips increases the stress on the musculoskeletal system leading to postural-instability. Aim: In study the effects of obesity on different segments of lower limb are being focused. Place & Duration: Data was collected in Pakistan. Study duration April 2020 to April 2021 Methods: After ethical approval, Consent and explanation of procedure the population was subdivided into three groups on the bases of BMI, with 50 samples in each group. For Pelvic tilt and Q-angle measurement the image captured with 13-megapixel camera and angle was measured[4]in computer with the help of Microdicom software. To evaluate foot posture, the foot posture index tool was used. The ICC95% calculated for validity and reliability of photography. Results: Validity and reliability test ICC 95% confidence interval for pelvic tilt and Q-angle measurement with photography method was 0.991 (0.974-.997) and 0.949(0.878-.981), with P-value 0.0001. There is significant different in pelvic tilt, Q-angle and foot posture of subjects with normal, overweight and obesity. Conclusion: Obesity has significant effect on Q-angle and pelvic tilt and foot posture. Key words: Q-angle, Posture, Pelvic, Obesity, Influence.
