Duration: 2 sessions per day, 5 days per week for 4 weeks
Control: conventional rehabilitation programme.
Group therapy. 2 or 3 sessions every day including physical, functional and cognitive aspects of occupational therapy, for 4 weeks.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Unclear risk Quote: "Ten of the participants were randomly assigned to a control group and 11 were allocated to the experimental group according to their admission sequence."
Comment: in view of the potential non‐random component (admission sequence) in the sequence generation process, we judged this to be of unclear risk of bias.
Allocation concealment (selection bias) High risk Quote: "Allocation according to admission sequence."
Comment: allocation by admission sequence is likely to have unblinded the allocation.
Blinding of participants and personnel (performance bias) 
 All outcomes High risk Quote: "limitation is that this was not a blinded study."
Comment: self‐reported outcomes are likely to be influenced by the knowledge of allocation.
Blinding of outcome assessment (detection bias) 
 Objective outcomes Low risk Quote: "Scoring was primarily conducted by a therapist who was not involved in the programme implementation."
Incomplete outcome data (attrition bias) 
 All outcomes Low risk Comment: no dropouts reported.
Selective reporting (reporting bias) Low risk All 3 rating scales listed in methods were reported.
Other bias Low risk Comment: no other sources of bias detected.
