Q angle is an essential parameter which is affected by many factors like age, sex, measurement techniques, pelvis position, foot position, the status of quadriceps and the body position used for measurement and higher Q angle associated with many knee pathologies.
Objective: Objective of this experimental study was to compare the Q angle among females with or without isometric contraction in standing and supine position in both right and left leg. Materials &Methods: Study Design: Explorative study design; Sampling Technique: Simple random sampling; Sample Size: 50 participants were included in the study with the age group of 18-30 years; Measurement of Q angle: The right and left sided Q angles were measured with subjects barefooted and in both standing and supine position. Q angle were measured using the universal goniometer; Statstics: Data was analyzed using SPSS software 20.0 version and Z test was used to compare the outcome measure
Results: Result of present study showed that there was a significant difference in comparing Q angle with or without contraction of quadriceps in lying and erect body positions but Q angle was more in standing position as compared to supine position and Q angle decreases with the isometric contraction of quadriceps in both body positions. When we compared bilateral variability in standing and supine position result was non-significant.
Conclusion: The present study concluded that there was Q angle decrement with static quadriceps contraction in both standing and supine positions but there was no significant bilateral variability.
