The Relationship Between Q Angle and Quadriceps Muscle Activation on Dynamic Balance in Women

Overview

The quadriceps angle (Q angle) is significant for the lower extremity alignment. Anatomical alignment of Q angle is related to Quadriceps muscle strength. Women have consistently been found to have larger Q angles than men and are more often affected due to patellofemoral problems. Quadriceps muscle activation and lower extremity alignment affect musculoskeletal health in women.The aim of this study wa s to determine the relationship between Q angle and quadriceps muscle activation on dynamic balance in women.

Objective: To determine the relationship between Q angle and quadriceps muscle activation on dynamic balance in women. Design: Correlational Study. Setting: University. Participants: Forth women will be included in the study. Interventions: Q angle in standing and supine positions, quadriceps muscle activation, static and dynamic balance and functionality were measured. Main Outcome Measurements: Q angle will measured with a tape measure; muscle activation will measured with Surface Electromyography (EMG) static balance will measured with Flamingo Balance Test (FBT); dynamic balance will measured with ProKin 252 Techno Body device; and, functionality will measured with Short Form Musculoskeletal Assessment (SFMA). Before the evaluation of EMG amplitude on dynamic balance position, the Q angle will measured in supine and standing positions. The EMG signals collected by measuring the muscle activation of the Vastus Medialis and Vastus Lateralis during dynamic balance position on the ProKin device will recorded.
