Work-related neck and shoulder pain are frequently reported in the workplace. Forward head posture (FHP) is associated with neck and shoulder pain. FHP is believed to alter the scapular kinematics and muscle activity which increases stress on the shoulder, leading to shoulder pain and dysfunction.
To compare the electromyography (EMG) activity of scapular upward rotators during isometric shoulder flexion with forward head posture versus neutral head posture in normal healthy individuals.
40 normal healthy individuals with age of 18–24 years who have no history of pathology will participate in the study and instructed to perform isometric shoulder flexion with the upper extremity in both the forward head posture (FHP) and neutral head posture (NHP). Surface electromyography (EMG) will be recorded from the upper and lower trapezius, and serratus anterior muscles.
Collected data are analyzed statistically by Paired t-test test.
There is increase in EMG activity of upper trapezius and lower trapezius and decrease in EMG activity of serratus anterior while forward head compare to neutral head posture.
