Methods	RCT Methods of randomisation: sealed envelope method
Participants	Country: USA Sample size: 21 participants (11 in experimental group and 10 in combined therapy group) Inclusion criteria: first clinical stroke diagnosis; time since stroke between 3 and 9 months; Mini‐Mental State Examination score of > 24; being able to stand for 2 minutes; passive range of motion ≥ 45° for shoulder abduction, flexion, or external rotation and pronation of the forearm; active wrist extension ≥ 10°; active thumb extension and ≥ 10° of extension in at least 2 additional digits Exlusion criteria: not described
Interventions	2 groups: 60 hours of repetitive task training over the course of 3 weeks 30 hours of repetitive task training plus 30 hours of robotic‐assisted training with the Hand Mentor device over the course of 3 weeks
Outcomes	Outcomes were recorded at baseline, at the end of intervention, and at 2 months postintervention Primary outcome measure: health‐related quality of life (SIS)
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Quote: "participants were randomly assigned by the sealed envelope method"
Allocation concealment (selection bias)	Unclear risk	It was not described whether the sealed envelopes were opaque
Blinding of outcome assessment (detection bias) All outcomes	Low risk	Quote: "Research staff blinded to treatment assignment conducted interview‐based outcome assessments."
Selective reporting (reporting bias)	Unclear risk	Insufficient information to permit judgement
