Detailed Description
This research project will achieve its objectives and outcomes in five phases:
There are 5 phases for this research work: (1) preparation phase, (2) Therapeutic intervention phase, (3) Evaluation phase, (4) Phase of data and statistical analyses, (5) The phase of Result Publication Phase.
Phase (1): Preparation phase.
This phase have been undertaken to set up and identify the inclusion and exclusion criteria of participant patients, determination of the sample size and randomization procedure for this study, purchasing the instruments that will be used in the study.
1.1 Setting up participant criteria. (This phase has completed) 1.2 Determination of the sample size and randomization procedure. Sample size: 40 patients will participated in this study. They will divided randomly to equal groups.
Randomization: (Not yet recruiting) In order to eliminate bias in treatment, randomization will be established for the patients who will be included in both experimental group A & control group B. It permits the use of probability theory to express the likelihood that any difference in outcome between treatment groups merely indicates chance. Evaluation of the patients with stroke will be performed by evaluators who will not participated in application of intervention and the therapists will be blinded from the randomization and blinding process. Simple randomization using a randomization table created by computer software (i.e. computerized sequence generation)
1.3 Purchasing the instruments. (This phase has completed) The following device has been already purchased: Armeo Functional upper extremity rehabilitation (MRF; Hocoma, Switzerland). (For treatment)
- Other evaluation instruments that will be used in this study are available in the University Research Labs
Phase (2): Therapeutic intervention phase. (This phase has not yet started)
Therapeutic intervention will be carried out three sessions per week for twelve successive weeks for both experimental and control groups. The treatment session will continue 2 hours with 15 minute rest between the first and the second hours. (More details are explained in the intervention section)
Phase (3): Evaluation phase. (This phase has not yet started)
The evaluation phase include the examination of the study predetermined parameters at both baseline, and 12 weeks after intervention commencement
Phase (4): Data and Statistical Analysis phase. This phase will start after all participants who will recruited for this study will be examined for the purposes of final collection of out-come data.
The statistical analysis will include:
The differences in demographics (such as age, height and weight) between study/experimental and control groups before treatment will be examined using one-way ANOVA.
Paired t test will be used to identify the mean differences in outcome measures within groups to compare the means of primary and secondary outcome measures between pre-treatment and post-treatment for each group.
One-way ANOVA with post-hoc tests will be used to identify the mean differences in primary and secondary outcome measures between study/experimental and control groups.
Phase (5): Result Publication Phase. This phase will start after all participants who will recruited for this study will be examined for the purposes of final collection of out-come data

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in the score of Fugl-Meyer Assessment Scale of Upper-Extremity (scale that assess the change in upper extremity motor functions)
Time Frame: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.] (i.e. Difference between Fugl-Meyer Assessment Scale Score of Upper-Extremity at both baseline and completion of 12 weeks of intervention)
|
The Fugl-Meyer Assessment of Upper Extremity (FMA-UE) is a stroke-specific, performance-based impairment index.
It measures the movement, coordination and reflex action of the shoulder, elbow, forearm, wrist and hand.
The scale includes 33 items divided into 4 subscales: (A) shoulder/elbow, 18 items, (B) wrist, 5 items, (C) hand, 7 items, and (D) coordination/speed, 3 items.
Each item is scored on an ordinal 3-point scale, where 2 points are assigned when the movement is performed fully, 1 point when performed partially, and 0 points when the movement cannot be performed.
A total score of 66 indicates better sensorimotor function.
Thus, the higher the score a patient will get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity motor functions.
|
[Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.] (i.e. Difference between Fugl-Meyer Assessment Scale Score of Upper-Extremity at both baseline and completion of 12 weeks of intervention)
|
Change in the score of The Action Research Arm Test (test that assess the change in upper extremity functions)
Time Frame: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between The Action Research Arm Test Score at both baseline and completion of 12 weeks of intervention)
|
The Action Research Arm Test (ARAT) is an evaluative measure to assess specific changes in limb function among individuals with hemiplegia.
It assesses a patient's ability to handle objects differing in size, weight and shape and therefore can be considered to be an arm-specific measure of activity limitation.
The ARAT consists of 19 items grouped into four subscales: grasp, grip, pinch, and gross movement.
The ARAT is scored on a four-level ordinal scale (0-3): 0 = cannot perform any part of the test, 1 = performs partially, 2 = take long time to complete the test, and 3 = performs the test normally.
The total score on the ARAT ranges from 0 to 57, with the lowest score indicating that no movements can be performed, and the upper score indicating normal performance.
Thus, the higher the score a patient will get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity motor functions.
|
[Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between The Action Research Arm Test Score at both baseline and completion of 12 weeks of intervention)
|
Change in the score of The Wolf Motor Function Test (test that assess the change in upper extremity motor ability)
Time Frame: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between The Wolf Motor Function Test Score at both baseline and completion of 12 weeks of intervention)
|
The Wolf Motor Function Test (WMFT) is designed to assess upper extremity motor abilities in patients with stroke through timed and functional tasks.
The WMFT consists of 15 timed items (6 items involve timed functional tasks, and 9 items consist of analyzing movement quality when completing various tasks), in addition to 2 items (7&14) are measures of strength.
The examiner should test the less affected upper extremity followed by the most affected side.
The 15 timed items are rated on a 6-point functional ability scale (0-5), score (0) means the patient is unable to use UE being tested while score (5) means the patient is able to use it and movement appears to be normal.
The total score on the WMFT ranges from 0 to 75.
Lower scores are indicative of lower functioning levels.
Thus, the higher the score a patient will get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity (UE) motor abilities.

Change in the Overall Stability Indices {percentage value (%)} for Postural Stability Test (test that assess the change in postural stability)
Time Frame: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between the overall stability indices score at both baseline and completion of 12 weeks of intervention)
|
The Biodex Balance System will be used to assess the change in the Overall Stability Indices of the Postural Stability Test.
The test includes measurement of the following indices: overall stability index, anteroposterior index and mediolateral index which represents the patient's ability to control his postural balance stability in all directions.
High values % represent less stability and the patient has difficulty in balance control.
On the other hand lower values are indicative of a better balance control.

Change in the Overall Stability Index {percentage value (%)}, and Time of Control {seconds} for Limit of Stability Test (test that assess the change in balance ability)
Time Frame: [Time Frame: Data collected at baseline, and 12 weeks after intervention commencement.](i.e. Difference between the overall stability index and the time of control at both baseline and completion of 12 weeks of intervention)
|
The Biodex Balance System will be used to assess the change in the Overall Stability Index and the Time of Control of the Limit of Stability Test.
This test involves measurement of overall directional control which represented as a percentage value (%).
The higher scores will indicate better balance control.
The test also include measurement of total time required to complete the test (seconds), improvement in this parameter requires minimizing the time recorded to complete the test.
