After the union of a shoulder dislocation, what method of strengthening is indicated for the patient?

The appropriate method of strengthening after a shoulder dislocation involves focusing on pain-free active range of motion (AROM) and isometric strengthening. In the initial phase of rehabilitation following a dislocation, it's essential to ensure that the shoulder is stabilized and that the exercises do not exacerbate any pain or further injury. Pain-free AROM allows the patient to regain mobility and function without placing undue stress on the recovering joint, which is crucial in the early stages of rehabilitation.

Isometric strengthening involves contracting the muscles without moving the joint, which can help maintain muscle tone and strength without risking aggravation of the injury. This approach is particularly beneficial in recovering from a dislocation, as it provides muscle activation while limiting motion at the joint, thereby promoting healing.

In contrast, isotonic strengthening exercises, while beneficial in other contexts, may pose a risk of provoking pain or causing re-injury immediately following a dislocation. Heavy weight lifting is not advisable early in the rehabilitation process as it can lead to insufficient recovery and increase the likelihood of complications. Dynamic stretching may be too aggressive at this stage since the primary goal is to establish a secure foundation before introducing more movement and flexibility into the treatment plan. Therefore, focusing on pain-free AROM and isometric strengthening is the
