___ injuries are a common result of working overhead.

• A. Shoulder
• B. Neck
• C. Both a and b
• D. Neither

Answer: (C)

Working overhead places the arms in an elevated, often awkward position for extended periods, loading both the shoulder and the neck. The shoulder bears most of the effort during elevation, so the rotator cuff tendons and subacromial structures are repeatedly stressed. That repetitive or forceful strain can lead to issues like impingement, rotator cuff tendinopathy, or bursitis, especially when posture is poor or breaks are infrequent. At the same time, keeping the head and neck extended or in forward-leaning position to see and reach overhead tightens and fatigues neck muscles such as the trapezius and levator scapulae, which can cause muscle strain and headaches. Because these stresses commonly occur together in overhead work, injuries in both the shoulder and the neck are typical outcomes. To reduce risk, use proper work heights, supports, and breaks, and perform stretches and posture checks during tasks.
