Input: Four trials (one on slings, three on strapping - 142 participants) met the inclusion criteria. One trial testing a hemisling versus no device reported that no participants had subluxation greater than 10 mm, the same number had lost more than 30 degrees of shoulder external rotation (Peto odds ratio (OR) 1.00, 95% confidence interval (CI) 0.1 to 9.3), and more participants in the hemisling group had pain (Peto OR 8.7, 95% CI 1.1 to 67.1). The other three showed that strapping was effective in delaying the onset of pain (weighted mean difference (WMD) 14 days, 95% CI 9.7 to 17.8), but was ineffective in reducing pain severity (WMD -0.7 cm on a visual analogue scale, 95% CI -2.0 to 0.7), increasing upper limb function (WMD 0.8, 95% CI -1.5 to 3.1) or affecting the degree of contracture (WMD -1.4 degrees, 95% CI -10.9 to 8.1) at the shoulder. There is insufficient evidence to conclude whether slings and wheelchair attachments prevent subluxation, decrease pain, increase function or adversely increase contracture in the shoulder after stroke. There is some evidence that strapping the shoulder delays the onset of pain but does not decrease it, nor does it increase function or adversely increase contracture.
Output:

This review of four trials found insufficient evidence to conclude whether supportive devices prevent subluxation or not and found no evidence to conclude whether supportive devices can reposition the head of humerus in the glenoid fossa of an already subluxed shoulder.
