Description of intervention(s) / exposure
Self-regulated constraint-induced movement therapy (SR-CIMT) - participants' non-hemiplegic arm was restrained in a mitt for 4 hours every day, 2 weeks, 5 days a week (therapy days) (CIMT) (the same CIMT protocol as in the CIMT group described under 'comparator/control treatment'); participants were taught using the self-regulation (SR) strategy to relearn the tasks; SR strategy involved participants self-reflecting on their abilities and deficits in performing the tasks, identifying problems and solutions in achieving the most independence in the tasks, and then actually carrying out the tasks. There were 10 tasks to practice in total, they included fold laundry, put clothes on hanger, brush teeth, dress upper garment, dress lower garment in week one; and use telephone, prepare a cup of tea, sweep floor, wash towel, wash dishes in week two.

In the 4 hours when the participants had their non-hemiplegic arm in the restrain, they received one hour therapist-guided training using SR strategy on task relearning as described above. Therefore, all participants received 10 one-hour therapist-guided training sessions (daily on weekdays, total two weeks). The intervention was delivered by occupational therapist. For the rest of the 3 hours in the restrain, the participants' wearing of the restrain was monitored by the nursing staff in the ward.

Comparator / control treatment
1. Control intervention - conventional occupational therapy involving therapist to demonstrate the adapted task performance followed by patient’s practice under supervision. They practised the same 10 tasks as in the SR-CIMT group described above. They received training for 2 weeks, 5 days a week (therapy days), the same as in the SR-CIMT and CIMT groups.

2. Constraint-induced movement therapy (CIMT) - non-hemiplegic arm was restrained in a mitt for 4 hours every day, 2 weeks, 5 days a week (therapy days); therapist provided demonstration on the adapted task performance with one arm (the side of participants' hemiplegic arm), and participants to practice the tasks with the unrestrained hemiplegic arm under supervision. They practised the same 10 tasks as in the SR-CIMT and control groups.

The same as the experimental intervention group (SR-CIMT), in the 4 hours when the participants had their non-hemiplegic arm in the restrain, they received one hour therapist-guided training using the strategy on task relearning as described above. Therefore, all participants received 10 one-hour therapist-guided training sessions (daily on weekdays, total two weeks). The intervention was delivered by occupational therapist. For the rest of the 3 hours in the restrain, the participants' wearing of the restrain was monitored by the nursing staff in the ward.

(2) had stroke onset of less than 3 months,
(3) were aged above 60,
(4) had 10 degree active extension in metacarpophalangeal joint and interphalangeal joint, 20 degree active extension of wrist joint.
Minimum age
60 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
(1) had excessive spasticity in the affected limb, as defined by a score of 2 or more on the Modified Ashworth Scale,
(2) had excessive pain in the affected limb, as defined by a score 4 or more using a Visual Analog Scale,
(3) had a score below 19 on the Mini-Mental Status Examination (MMSE), and
(4) had diagnosed of depression according to DSM-IV criteria.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients were randomized by drawing lots using three sealed opaque envelopes (for the three intervention groups). The randomization was conducted by a blinded researcher who was not involved in delivering the interventions or study measures.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation by drawing lots using three sealed opaque envelopes (for the three intervention groups)

Efficacy
Statistical methods / analysis
Using PASS 13 software, based on the parameters used for ANOVA tests, and with reference to the results obtained from the previous CIMT study, the total sample size of 20 in each group would give a power of 80%, an alpha value of 0.05 and effect size of 0.50.

Differences among the three groups in demographic variables were assessed using analysis of variance (ANOVA) and chi square test; and in study measures at baseline were assessed using the Kruskal-Wallis test. For changes in the study measures among baseline, after intervention and one month after the intervention completed in each group, Friedman test was used. Differences in the gains across the study measures, before and after intervention, among the three groups were measured using the Kruskai-Wallis test. Mann-Whitney U test was used to further test the differences, if any, between any of the two groups. Significance level was set at a 2-tailed P<0.050 for all comparisons.

Summary
Brief summary
Emerging research suggests the use of self-regulation (SR) strategies at improving functional regain in patients with brain injury. SR is proposed to produce an added effect to the effective constraint-induced movement therapy (CIMT). This study aimed to examine the efficacy of a self-regulated CIMT program (SR-CIMT) for function regain of patients with sub-acute stroke.
It was hypothesized that participants receiving the combined treatment (SR and CIMT) would have a better functional regain.
