Brief Summary

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.

Conditions

Physiotherapy and Rehabilitation

Keywords

Q angle; Quadriceps muscle activation; EMG; Balance

Outcome Measures

Primary Outcomes (3)

• Q angle evaluation

  The Q angle was measured with a standard universal goniometer. It was measured by drawing a line from the Anterior Superior Iliac Spine to the center of the patella and a second line from the center of the tibial tubercle to the center of the patella.

  5 minutes

• Electromyographic (EMG) measurements

  EMG biofeedback is a device that detects neuromuscular contractions and provides feedback signals to the subject. During the ProKin 252 Techno Body balance system, Vastus Medialis and Vastus Lateralis muscles activity levels were recorded at 1000-Hz sample data-regulating Surface EMG device and analyzed using the Biometrics Datalog (UK) system.

  15 minutes

• Dynamic Balance Evaluation

  Dynamic balance was evaluated by ProKin 252 Techno Body balance device. The participants were taken to the balance platform on the right foot with their eyes open, after determining the reference interval and setting the test time as 30 seconds.They were instructed to stay balanced on the platform

  15 minutes

Secondary Outcomes (2)

• Static Balance Evaluation

  5 minutes

• Functionality Assessment

Study Arms (1)

Experimental group

EXPERIMENTAL

Before the evaluation of EMG amplitude on dynamic balance position, the Q angle was 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 were recorded. Q angle evaluations, static and dynamic balance and functional status of all participants were evaluated.

Other: Evaluation of Q angle and Quadriceps muscle activation on dynamic balance position

Interventions

Evaluation of Q angle and Quadriceps muscle activation on dynamic balance position OTHER

Evaluation of Q angle, Quadriceps muscle activation, static and dynamic balance and functionality of all individuals was done.
