Information about the method (ie, design, participants, intervention, measures) and outcome data (ie, number of participants who could walk independently, mean (SD) walking speed, and walking capacity) were extracted. Authors were contacted where there was difficulty extracting and interpreting data from the paper. The post-intervention scores were used to obtain the pooled estimate of the effect of intervention at 4 weeks (short term) and 6 months (long

term). A fixed-effects model was used. In the case of significant statistical heterogeneity (I2 > 25%), a random-effects model was applied to check the robustness of the results. The analyses were performed using the MIXa program (Bax et al 2006, Bax et al 2008). Dichotomous outcomes (ie, amount of independent walking) were reported as risk Anti-diabetic Compound Library difference (95% CI) whereas continuous outcomes (ie, walking speed and capacity) were reported as the weighted mean difference (95% CI). The search returned 2425 papers. After screening the titles and abstracts, 41 papers were retrieved for evaluation of full text. Another two papers were retrieved as a result of searching trial registries. Thirty-six papers failed to meet the inclusion criteria and therefore Gefitinib seven papers (Ada et al 2010, Dean et al 2010, Ng et al 2008, Pohl et al 2007, Du et al 2006, Schwartz et al 2009, Tong et al 2006) were included in the

review. One trial was reported Farnesyltransferase across two publications (Ada et al 2010, Dean et al 2010), so the seven included papers provided data on six studies. See Figure 1 for flow of studies through the review. See Table 1 for a summary of the excluded papers (see eAddenda for Table 1). Six randomised trials investigated the effect of mechanically assisted walking on independent walking. Five trials investigated the effect on walking speed. Two trials investigated the effect on walking capacity. The quality of the included studies is outlined in Table 2 and a summary of the studies is presented in Table 3. Quality: The mean PEDro score of the

included studies was 6.7. Randomisation was carried out in 100% of the studies, concealed allocation in 33%, assessor blinding in 66%, and intention-to-treat analysis in 83%. Only one trial reported a loss to follow up greater than 15% – and that was only 16%. No study blinded participants or therapists, due to the inherent difficulties associated with these interventions. Participants: The mean age of participants across studies ranged from 57 to 73 and they were on average within the first month after their stroke. Non-ambulatory was defined as Functional Ambulatory Category < 3 (five studies) and Motor Assessment Scale Item 5 score < 2 (one study). Intervention: Mechanically assisted walking included treadmill with harness (two studies), treadmill with robotic device and harness (Lokomat) (one study) and electromechanical gait trainer with harness (three studies).
