Overview
Brief Summary
Stroke is one of the commonest causes of severe disability in adults. Stroke often results in spasticity and motor impairments in the upper limb. Permanent upper extremity impairments can lead to limitations in activities of daily living, social participation, and quality of life. Spasticity may obscure motor learning ability after stroke. Spasticity control is one of the main aims of most therapists in the rehabilitation process for patients with chronic stroke. Traditional approaches for managing spasticity may not be enough for gaining satisfactory results. Virtual reality-based therapy is one of the most innovative and developments in rehabilitation technology. It could be effective in accelerating motor recovery and modulating spasticity for the involved upper limbs. The purpose of this study was to examine the impact of virtual reality-based therapy on upper limb spasticity and motor functions in patients post-stroke.
Detailed Description
Stroke is an acute, medical event, which mainly results in neurological damage leading to disability and mortality. Stroke is a common, serious, and disabling problem. The most widely recognized impairment caused by stroke is motor impairment of one side of the body called hemiplegia, which restricts function in muscle movement or mobility. Following a stroke, many upper limb impairments may influence the patient's ability to perform functional activities. These include spasticity, muscle weakness, restricted and in-coordinated movement. The impact of upper limb dysfunctions on participation in home, work, community life, and daily living activities is great. Upper limb recovery after stroke is unacceptably poor; with only 50% of stroke survivors likely to regain some functional use. In many neurological disabilities associated with spasticity such as hemiplegia post-stroke, the rehabilitation process is of long duration and clinicians face the challenge of identifying a variety of meaningful and motivating intervention tasks that could be effective in controlling spasticity and preventing its negative hazards. Current rehabilitation techniques have focused on teaching and reinforcing different strategies that encourage the use of the non-involved upper extremity to decrease functional limitations. Treatment options for controlling spasticity and enhancing upper limb functions include physical therapy, occupational therapy, neurodevelopmental therapy, peripheral splinting and casting, constrained induced movement therapy, pharmacotherapy (e.g., botulinum toxin type A), and surgery. Till now, there is a lack of strong evidence of successful treatment with any of these approaches. Virtual reality is a relatively recent approach to stroke rehabilitation. It has been shown to be an interactive and enjoyable medium that, with sufficient use, may improve upper limb motor function in adults with stroke. Enhanced feedback provided by a virtual reality system has been shown to promote motor learning in normal subjects. The main advantage of virtual game-based rehabilitation over conventional approaches is the inclusion of an interactive and motivating exercise environment. Until now, there have been limited researches involving the inclusion of virtual reality-based therapy systems in neuro-rehabilitation and spasticity management of the involved upper limb for hemiplegic patients post-stroke. Therefore, the purpose of this study was to evaluate the efficacy of virtual reality technology on modulating spasticity and improving the function of the involved upper extremity in patients having a chronic stroke.

Eligibility Criteria
Inclusion Criteria
- •The inclusion criteria were as follow:
- •Participants were diagnosed as chronic stroke patients.
- •Participants were selected to be in the spastic phase, 6-24 months following a first stroke.
- •The degree of spasticity in the affected upper limbs, was ranged between grades (1, 1+\&2) according to Modified Ashworth Scale.
- •Participants were all between 50 and 60 years old, of both sexes.
- •Participants were cognitively able to understand and follow instructions.
- •Participants had the ability to extend their wrist joints at least 20° and fingers 10° from full flexion. This range allowed participants to engage easily in performing a designed functional program.
Exclusion Criteria
- •The exclusion criteria were as follow:
- •Participants who were with any orthopaedic condition or fixed deformity that interfere with the upper limb functions.
- •Participants who were with spasticity more than score 2 according to the Modified Ashworth Scale.
- •Participants who had cognitive or perceptual problems.
- •Participants with surgical interference for the upper limb and spine within the previous 2 years.
- •Participants with seizures, visual impairments, or auditory problems.
- •Participants who had shoulder pain on a visual analogue scale of \> 6/
- •Participants who had Botulinum Toxin in the upper extremity musculature six months before baseline assessment.
Outcomes
Primary Outcomes
Change in the Modified Ashworth Scale (scale that assess the change in muscle tone)
Time Frame: [Data was collected at baseline, and 12 weeks after intervention commencement.] (i.e. Difference between the degree of muscle tone at both baseline and completion of 12 weeks of intervention)
Modified Ashworth Scale was used to evaluate the degree of spasticity in the involved upper limb in the elbow and wrist joints. MAS is a valid and a reliable scale to evaluate the degree of muscle tone for all participants pre and post treatment. It is scored on a 6 -graded ordinal scale.
Change in the score of The Action Research Arm Test (test that assess the change in upper extremity functions)
Time Frame: [Data was 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 get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity motor functions.
Change in the score of The Wolf Motor Function Test (test that assess the change in upper extremity motor ability)
Time Frame: [Data was 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 get after completion of the treatment program compared to the baseline score, the better the improvement in upper extremity (UE) motor abilities.
Secondary Outcomes
- Change in the upper limb' joints range of motion (in degree)([Data was collected at baseline, and 12 weeks after intervention commencement.] (i.e. Difference between the degree of upper limb' joints range of motion at both baseline and completion of 12 weeks of intervention))
- Change in the Hand Grip Strength of the involved upper extremity (Kg) (which indicate the change of the strength of the involved hand muscles in patients with stroke).([Data was collected at baseline, and 12 weeks after intervention commencement.] (i.e. Difference between hand grip strength at both baseline and completion of 12 weeks of intervention))
