STROKE, HEMORRHAGIC STROKE, ISCHEMIC STROKE
The randomization was done in different stages. First, the study sample of 108 subjects was selected by generating random numbers from filtered 187 chronic stroke patients. Then, the patients were divided into two groups as ischemic stroke and (76) and hemorrhagic stroke (32).The randomization process for the ischemic group or hemorrhagic group was followed separately. Seventy-six ischemic patients were randomly divided into 19 groups containing four patients per each and 32 hemorrhagic patients were randomly divided into eight groups containing four patients per each. Then treatment appointments were given as one group for one day (4 ischemic patients or 4 hemorrhagic patients per day). The first ischemic patient or the first hemorrhagic patient of the group was selected to either experimental or control group by ‘Envelop method’ (same-sized and same-colored two envelops) [Ethical clearance (2019/EC/35) for this study was obtained from Ethics Review Committee, Faculty of Medicine, University of Peradeniya, and it was registered under Sri Lanka Clinical trial Registry with the registration number of SLCTR/2019/040 to conduct as a clinical trial.
