BACKGROUND: Supportive devices such as slings, wheelchair attachments and orthoses have been used to treat subluxation of the shoulder after stroke. OBJECTIVES: To investigate the effect of supportive devices in preventing subluxation, re-positioning the head of humerus in the glenoid fossa, decreasing pain, increasing function and adversely increasing contracture in the shoulder after stroke. SEARCH STRATEGY: We searched the Cochrane Stroke Group Trials Register (last searched on 22 March 2004). In addition, we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1, 2004), MEDLINE (1966 to March 2004), CINAHL (1982 to March 2004), EMBASE (1974 to March 2004), AMED (1985 to March 2004) and the Physiotherapy Evidence Database (PEDro, March 2004). We also handsearched conference proceedings and contacted authors for additional information. SELECTION CRITERIA: Studies were included if they were: randomised, quasi-randomised or controlled trials; participants had a stroke; intervention was supportive devices; and subluxation, pain, function or contracture were measured. DATA COLLECTION AND ANALYSIS: Two independent reviewers examined the identified studies which were assessed for methodological quality and analysed as (1) supportive devices versus no supportive devices or (2) two supportive devices. MAIN RESULTS: 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. AUTHORS' CONCLUSIONS: 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.
BACKGROUND: Patients with osteoarthritis of the knee can be treated with a brace or orthosis (shoe insole). The main purpose of these aids is to reduce pain, improve physical function and, possibly, to slow disease progression. OBJECTIVES: To assess the effectiveness of a brace or orthosis in the treatment of osteoarthritis of the knee. SEARCH STRATEGY: We searched Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE (Current contents, Health STAR) up to October 2002. The reference lists of the publications in the identified trials were also screened. SELECTION CRITERIA: Extracted studies were included in the final analysis if they met the pre-defined inclusion criteria: 1) a randomised controlled clinical trial or a controlled clinical trial, 2) all patients had osteoarthritis of the knee, 3) the intervention in one of the studied groups was a brace or an orthosis. DATA COLLECTION AND ANALYSIS: Two reviewers independently selected the trials and assessed the methodological quality using the Delphi-list and one additional question about care programs. Three reviewers independently extracted the data on the intervention, type of outcome measures, follow-up, loss to follow-up, and results, using a pre-tested standardized form. Study authors were contacted for additional information. MAIN RESULTS: Four trials involving a total of 444 people were included in this review. One study investigated a knee brace and three studies examined different types of orthoses for medial compartment osteoarthritis of the knee. Two studies were of high methodological quality while the other two studies were low. Notably, the randomisation and the blinding procedures were either insufficient or not described. The follow-up period (six weeks to six months) was too short to demonstrate long-term results. Pooling was difficult primarily due to the heterogeneity of the data and the way the information was presented. The pain, stiffness and physical function (WOMAC and MACTAR) scores of a brace group showed greater improvement at six months compared with a neoprene sleeve group, which showed greater improvement compared with a control group. The numbers of days of non-steroidal anti-inflammatory drug (NSAID) intake decreased significantly (relative percentage difference 23.9%) compared with baseline in a group with laterally wedged insoles,and remained unchanged in the neutrally wedged group. Patient compliance with the laterally wedged insole was significantly better compared with the neutrally wedged insole. In one study, the Visual Analogue Pain (VAS) pain score was significantly decreased from baseline in a strapped insole group (RPD - 24%), but not in the traditional lateral wedge group, but this strapped insole showed more adverse effects (popliteal pain, low back pain, and foot sole pain) compared with the traditional lateral wedge insole. Pain during bed rest, after getting up, after getting up from seated position and walking distance was significantly improved in a subtalar strapped group compared with baseline, and no improvement was found in a sock type group. No studies were found that assessed the effectiveness of a brace or orthosis to treat lateral compartment osteoarthritis or general osteoarthritis of the knee, or that compared a knee brace with a wedge insole, or that compared a brace or orthosis with operative treatment. AUTHORS' CONCLUSIONS: Based on one brace study we conclude there is limited evidence that: a brace has additional beneficial effect (WOMAC, MACTAR, function tests) for knee osteoarthritis compared with medical treatment alone.(Silver) a sleeve has additional beneficial effect (WOMAC, function tests) for knee osteoarthritis compared with medical treatment alone.(Silver) a brace is more effective (WOMAC, function tests) than a neoprene sleeve.(Silver) Based on 3 orthoses studies, of which 2 were high quality, (n=2) we conclude there is limited evidence that: a laterally wedged insole decreases NSAID intake compared with a neutral insole. (Silver) patient compliance is better in the laterally wedged insole compared with a neutral insole. (Silver) a strapped insole has more adverse effects than a lateral wedge insole. (Silver).
