If a client shows an upper extremity movement impairment syndrome, which muscles are likely tight?

When considering upper extremity movement impairment syndromes, it is essential to understand the role of the muscles involved in shoulder and scapular mechanics. In this case, the upper trapezius and levator scapulae are commonly associated with tightness in individuals who exhibit movement impairment.

The upper trapezius is a prominent muscle involved in elevating the scapula and plays a significant role during shoulder movements. When this muscle becomes overactive and tight, it can lead to restrictions in shoulder mobility and contribute to compensatory movement patterns. Similarly, the levator scapulae functions to elevate and rotate the scapula, and excessive tension in this muscle can result in altered mechanics and potential pain in the neck and shoulder region.

Both of these muscles often become hypertonic due to poor posture—such as rounded shoulders or forward head position—which is prevalent in individuals who spend extended periods in front of a computer or device. Addressing the tightness of the upper trapezius and levator scapulae is crucial in corrective exercise because releasing tension in these muscles can help restore proper movement patterns and improve shoulder function.

In contrast, while the lower trapezius and serratus anterior are important stabilizers of the scapula that may be underactive in certain
