Which muscle group is most likely to be weak in a client with a history of being a waitress and experiencing shoulder pain?

In a client with a history of being a waitress and experiencing shoulder pain, the rotator cuff muscles are most likely to be weak. These muscles play a critical role in stabilizing the shoulder joint, particularly during overhead activities and repetitive motions, which are common in the daily routines of waitstaff. Carrying trays, reaching for items, and lifting can lead to overuse of certain muscles while neglecting the rotator cuff, resulting in weakness or dysfunction.

Shoulder pain often signifies underlying issues with the rotator cuff, including muscle imbalances, poor coordination, or even tendinopathy. As these muscles are integral to maintaining shoulder stability and mobility, weakness in this group can contribute to pain and injury, especially in individuals engaged in repetitive or overhead movements associated with their occupation. Therefore, targeting the rotator cuff for strengthening and rehabilitation can be essential for alleviating pain and restoring function in clients with similar histories.
