Quizplus · Accepted Answer

The upper trapezius muscle becomes overactivated and tightened in a person with both forward head posture and forward shoulder posture as it is responsible for elevating and upwardly rotating the shoulder blade, which is necessary when the arms are elevated in front of the body. In these postural imbalances, the upper trapezius takes on more of the workload, leading to tension and tightness. The lower trapezius, middle trapezius, and serratus anterior may be weakened in these postural imbalances.
