Abstract

Background

Shoulder subluxation is a common post-stroke complication affecting up to 80% of the stroke subjects. The pathomechanics at the skeletal level does not provide the structural base for the neural-motor recovery. The management of subluxed shoulder has always been a challenge, complicating the motor and functional recovery.

Objective

To review the available studies of rehabilitation interventions for reduction of subluxed shoulder and to explore the evidence for impact of subluxation on motor recovery.

Method

PubMed, the Cochrane Central Register of Controlled Trials, DORIS, PEDro, and OTseeker databases were searched using the keywords: Stroke and Shoulder and Subluxation. The experimental, quasi-experimental, and single group studies investigated the rehabilitation methods to reduce the subluxation were selected. A narrative synthesis of the findings from the selected studies was carried out.

Result

2717 studies were identified and 22 studies (14 RCTs or controlled trials and 8 pre-post-single group studies) were finally selected for the review. The rehabilitation intervention: Functional electrical stimulation (FES)/electrical stimulation (11), orthosis/support (07), taping (02), and robotic training and other methods (02) were reviewed. FES is effective in reducing subluxation in acute stage. Shoulder support or orthosis while in situ may reduce the subluxation temporarily. X-ray was the most commonly used assessment tool for the subluxation. Implication of the rehabilitation technique on motor recovery has not been investigated.

Conclusion

No technique could effectively reduce the subluxation and facilitate the upper limb recovery. Further studies integrating the usual motor training and the subluxation rehabilitation are warranted. Future trials using more precise and valid tool such as ultrasonography are also needed.
