Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention group received CCT focusing on practice of task-oriented activities for 60 – 90 minutes, once a week for total of 12 weeks, CCT exercise components include: aerobic walking, sit to stand, step-up, heel lift, standing with base of support (BOS) constrained, obstacle walking course, tandem walking and task oriented training of upper limb task as its name suggests is an upper limb task. After the completion of all stations, only patients in high function group were given the opportunity to participate in games such as badminton or Ping-Pong. Intensity of the exercise depends on the patient's ability within the allocated 5 minutes for each stations except for aerobic walking exercise which begins with 20 minutes and progressed up 40 minutes by the end of the 12th week.. Intensity performed by patients were recorded and it was ensured that the intensity was progressed every week in terms of number of repetitions, using weights and increasing the complexity level of the task such as counting backward while performing tandem walk.. Therapist administered the treatment in group format of six to eight in each group and participants were given one to two minutes transition time between each stations. Participants were categorized into two sub-groups; low functioning (Modified Rankin Scale of score 3) and high functioning groups (Modified Rankin Scale of score 2 and below). In high functioning group of eight participants, two groups was further formed with one therapist to four patients (1:4). In low functioning group of six participants, two groups with three participants in each group with the ratio of one therapist to three participants (1:3) were formed. Adherence was monitored by maintaining attendance of each patient every session. Patient who failed to attend to the therapy session were followed up by phone calls and a gentle reminder of the next session.

Rehabilitation
Comparator / control treatment
The control group received usual therapy administered for 60-90 minutes, once weekly for a total of 12 weeks. Usual therapy was administered in a one to one sessions. Usual therapy was administered by physiotherapists who are experienced in stroke rehabilitation. Patients in the usual therapy received individualized therapy focusing on intervention targeting impairments and the problem presented by the patient. The components of the intervention were based on therapist’s preference and patients’ need. The intervention included electro therapeutic modalities, task specific training and special retraining technique or even basic therapeutic exercise.

Instrumented Timed Up and Go Test (ITUG)

This study used iTUG with Mobility lab sensors. The operational definition of the mobility in this study focused on gait parameters involving lower limb gait measures and also turning. The definition of categories of lower limb gait measures and turning are described below:

Lower limb gait measures provide data on (1) total duration required to complete the trial (seconds) (2) stride velocity which is the walking speed and measured in percentage of subject’s height / second, (3) stride length which is the distance between two consecutive right and left foot falls measured in percentage of subject’s height (4) gait cycle time which is the duration of a complete gait cycle measured in seconds,(5) double support which is the percentage of a gait cycle that both feet are on the ground measured as percentage of gait cycle time (GCT), (6) swing phase which is average percentage of gait cycle that either foot is off the ground, measured as percentage of GCT, (7) stance phase which is the average percentage of gait cycle that either foot is off the ground measured in percentage of GCT (Ambulatory Parkinson Disease Monitoring APDM 2014).

Turning measures provide data on (1) duration of turning which is the duration of 180 degrees turn, measured according to the mathematical model of turning in seconds, (2) peak turn velocity which is the peak (95 percentage) angular velocity of trunk during turning in seconds, (3) number of steps taken which is defined as number of steps during 180 degrees turn and steps which are at least 50 percentage within turning period and counted in numbers (APDM 2014).

Procedures: Assessors measured 7 meters on the floor and place tape at the two ends. An armless chair was placed at the start end before the tape. ITUG was selected from the sessions tab in the computer, and start trial button was pressed. Participants were instructed to sit comfortably in the chair with their arms on their legs, and back against the seat. When the participants is ready, the button record was pressed and the trial began to count down from 3 seconds.

The participants were instructed to rise from the chair without using their arms and begin walking. After participants crossed the 7m end tape, they will be instructed to turn 180 degrees and walk back. Once they arrived at the chair they should turn 180 degrees, and sit down. Trial was terminated when the patient rests their back against the back of the seat (APDM 2014).

Berg Balance Scale (BBS)

BBS is a 14-item scale that quantitatively assesses static and dynamic balance of community-dwelling stroke survivors via direct observation of performance of subjects within 10 to 20 minutes. Each items will be scored from 0 to 4, with score 0 representing an inability to complete the task and score of 4 representing independent item completion. Global score is calculated out of 56 points with scores of 0 to 20 representing balance impairment, 21 to 40 representing acceptable balance, and 41 to 56 representing good balance. BBS requires minimal equipment such as chair, stopwatch, ruler, step and space plus no specialized training required.

Reintegration to Normal Living Index (RNLI)

RNLI comprises of 11 declarative statements that are scored on a 10cm visual analog scale (VAS) and measures the perceived reintegration to normal living of the subjects (Pang et al. 2011). This study required subject to fill the questionnaire as RNLI requires only 10 min and no formal training required to use it (Pang et al. 2011). The RNLI consists 11 items which are of 7 domains which are indoor, community and distance mobility, self-care, daily activities (work and school), recreational and social activities, family role(s), personal relationships and presentation of self to others and general coping skills (Rehab Measures 2014). First 8 items represent 'daily functioning' and the remaining 3 items represent 'perception of self' (Rehab Measures 2014). This study used scoring method of 10 cm visual analog scale in which 0 indicates “does not describe my situation” and 100 indicates “fully describes my situation”. The total score which are sum of all 11 items are divided by 110 and multiplied by 100 for adjusted score

Health Related Quality of Life (HRQoL)

HRQoL was assessed using EQ-5D-5L which is a validated, self-report, non-disease-specific tool to measure health outcome. EQ-5D-5L is also valid, reliable and responsive in chronic stroke patient and recent study had proven the suitability of employing EQ-5D as outcome measure in neurological clinical trials (Hunger et al. 2012).
The EQ-5D-5L consists of 2 pages - the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS). The EQ-5D questionnaires consists of five questions which represent five dimensions of HRQoL such as mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. Each question comes with a single digit response option.
EQ-5D-5L provides five levels of response for each question which are Level 1: indicating no problem, Level 2: indicating slight problems, Level 3: indicating moderate problems, Level 4: indicating severe problems, Level 5: indicating extreme problems. Subjects are only required to tick one option for each question.
The digits for all five questions was combined into a five-digit number describing the respondent’s health state. The EQ-5D has two pages which are the EQ-5D descriptive system and the EQ visual analogue scale (EQ VAS) (EuroQOL Group 2014). This result of EQ-5D-5L health states was converted into a single index value which are presented in country specific value sets. The utility score range between ‘0’ and ‘1’ representing a numeric valuation of the QoL, where ‘0’= death and ‘1’= perfect health. Population utility scores by geographical regions are used based on Thai population (Nor Azlin Mohd Nordin PhD thesis, 2013).

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Patients were recruited based on list of patient available in the physiotherapy clinic. Stratified block randomisation were used to randomize patients based on guideline proposed by Doig and Simpson (2005). Stratification was based on age and disability level. Participants were first stratified based on age into two age groups namely below 65 years old and above 65 years old. The second stratification was based on the functional ability measured by Modified Rankin Scale (Score 3: low function group, Score 2 and below: high function group). Therapist independent to the research was asked to pick envelope with the names which fits into each strata.

Statistical methods / analysis
Main results for each objectives were analysed using Mixed Model ANOVA with SPSS version 20. Gpower version 3.1 was used to calculate sample size. Detailed calculations of the effect size were based on information from previous study by Ko et al (2015), a similar study to the currents study with mean and standard deviation of experimental group are 26.70 +/- 20.9 seconds respectively. The mean and standard deviation of control group are 41.50 +/- 25.30 seconds respectively. The formula for effect size, f calculation for Gpower software version 3.1 was obtained from a paper by Cunningham and Gardner (2007).In Gpower version 3.1, F test, ANOVA repeated measure, within between interactions and effect size of 0.35 were entered into the Gpower version 3.1. Therefore, with alpha value of 0.05 and power of 0.98, a total of 36 patients were needed and this study recruited 40 patients.
