Brief summary: The goal of this observational study is to investigate the effect of head posture on trapezius muscle activity and ratios during wall slide exercise. The main question the study aims to answer is:

•How does the trapezius muscle activity change during wall slide exercise when performed with a natural head posture and the corrected head posture? The participants performed wall slide exercise with their natural head posture and the corrected posture. For both interventions, muscle activity of the lower, middle and upper trapezius was measured with surface electromyography(EMG) Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) in the ascending, stationary and descending phases of the exercise.

Detailed description: Healthy individuals between the ages of 18 and 35 who have not had any pain in the upper extremity for the last 6 weeks, have musculoskeletal system pathologies of the upper extremity and/or any surgery were included in the study. Individuals who have had pain in the shoulder area for the last 6 weeks, had shoulder injury and/or shoulder surgery, have neurological, rheumatological or systemic diseases and body mass index (BMI) greater than 30 kg/m2 were excluded. Participants were asked to perform wall-slide exercise with both natural head posture and corrected head posture, separately. During the wall-slide exercise, muscle activations of upper trapezius (UT), middle trapezius (MT) and lower trapezius (LT) were measured with surface EMG Noraxon MiniDTS system (Noraxon, USA, Inc, Scottsdale, AZ) in the ascending, stationary and descending phases of the exercise.
