| Methods | Design: multicentre randomised trial of cardiorespiratory training plus usual care versus non‐exercise intervention plus usual care ‐ during usual care Randomisation: mechanism ‐ computer; method ‐ blocks size of 10 participants Allocation concealment: numbered, sealed envelopes Blinding: investigator blinded; participants encouraged to maintain blinding; efficacy unknown ITT: yes, but participants were excluded after recruitment and baseline assessments due to discharge Measurements: end of intervention (12 weeks) and at follow‐up Withdrawals: intervention group (12 participants: 4 before and 8 after the 12‐week assessment); control group (12 participants: 2 before and 10 after the 12‐week assessment) Reasons unclear but included early discharge |

| Participants | Randomised: 84 participants Intervention: 40 participants; males 20, females 20; age 47.0 years (SD 13.1); 144 days (SD 84) post‐stroke Control: 44 participants; males 29, females 14; age 50.3 years (SD 10.1); 184 days (SD 127) day post‐stroke Inclusion criteria: single stroke; could comply with planned interventions; could sit on a cycle ergometer Exclusion criteria: likely to be inpatient for < 3 months; impairments severe enough to limit training compliance and participation; cardiac disease; co‐morbidities contraindicated for exercise | |
| Interventions | Intervention: cardiorespiratory training; cycle ergometry at 60% to 80% of age‐related heart rate maximum for up to 30 minutes per day 3 days per week for 12 weeks Control: relaxation ‐ programme individualised: included breathing exercises, progressive muscle relaxation, autogenic exercises, visualisation techniques Setting: multicentre, 4 rehabilitation units | |
| Outcomes | Included outcomes: FIM; BI (0 to 20 scale); NEADL; RMI; HADS; BBS; gait maximum speed; maximum cycling workload (data transformed to Log base e); BMI Other outcomes: fatigue questionnaire | |
| Notes | Mixed brain injury data provided by authors; stroke‐only data retained and re‐analysed. High rate of missing data made statistical analyses difficult | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | Computer‐based block (n = 10) randomisation |
| Allocation concealment (selection bias) | Low risk | Numbered, sealed envelopes |
| Blinding (performance bias and detection bias) All outcomes | High risk | Attention control |
| Blinding of outcome assessment (detection bias) All outcomes | Low risk | Investigator blinded; participants encouraged to maintain blinding; efficacy unknown |
| Incomplete outcome data (attrition bias) End of intervention | High risk | ITT employed 6/84 (7%) lost: intervention group 4; control group 2 Reasons for losses not clear but included exclusion after recruitment and baseline assessments due to discharge Large amounts of missing outcome data |
| Incomplete outcome data (attrition bias) End of follow‐up | High risk | ITT employed 24/85 (29%) total losses; intervention group 8; control group 10 |
| Selective reporting (reporting bias) | Unclear risk | Protocol not available |
| Other bias | Unclear risk | Unclear |
| Imbalanced exposure | Low risk | Balanced exposure |
