The Relationship Between Q Angle and Quadriceps Muscle Activation on Dynamic Balance in Women
A study testing Evaluation of Q angle and Quadriceps muscle activation on dynamic balance position in people with Physiotherapy and Rehabilitation, run by Istanbul Medipol University Hospital at 1 site in Turkey (Türkiye).
Trial 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. Read more about this study

About this study
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.
Read the detailed description
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: 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.
Measured: 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
Measured: 15 minutes
Secondary outcomes (2)
Static Balance Evaluation
Static balance was assessed with Flamingo Balance Test (FBT) in open and closed eyes conditions.The subjects stood on the beam which was 50 cm long, 5 cm in height and 3 cm wide. Then the instructor started the stopwatch and the subjects tried to stand in this position for one minute. When the time was over, the subjects' attempts after they fell were counted and this score was recorded
Measured: 5 minutes
Functionality Assessment
The functional status of subjects was evaluated with the Short Musculoskeletal Function Assessment Questionnaire (SMFA).
Measured: 5 minutes
