Clinical Trial Summary

A stroke is a significant contributor to functional decline and long-term disability. The reduction of obesity and improvement in quality of life are directly correlated. Many post-stroke patients experience persistent upper extremity dysfunction. The study aims to compare cross-education non-paretic limb training versus mirror therapy on upper limb strength and dexterous movement of hand in stroke survivors This randomized clinical trial will be conducted at DHQ Hospital Sargodha over a duration of six months. The sample size will consist of 26 participants. Participants which meet the inclusion criteria will be selected through Non probability convenience sampling technique, which will further be randomized through computer engendered in blocks by using basic number generator.13 participants will be assigned to Cross education group and 13 participants will be assigned to Mirror Therapy group. Data will be using various assessment tools, including the Action Research Arm Test (ARAT) for functional limitation, Fugl-Meyer Assessment-upper extremity (FMA-UE), Stroke Impact Scale (SIS) for hand dexterity and function. Hand held dynamometer will be used for Grip Strength Test. Pre intervention assessment will be conducted for both groups. The effects of intervention will be measured at pretreatment ,3rd week and post intervention. Data analysis will be performed by using SPSS (Statistical Package for Social Sciences) 23 version.

Description:

A stroke or CVA is characterized by the sudden onset of focal neurological dysfunction symptoms that persist for more than 24 hours (or cause death earlier) and are brought on by an acute vascular injury to a specific area of the brain. Overall, a stroke creates a blockage in the delivery of blood and oxygen to a particular region of the brain, which results in cell death, long-term or lifelong impairments, or even death. Issues with paralysis, motor control, pain-related sensory problems, language usage or comprehension, thinking, memory, and emotional challenges are just a few examples of disabilities.

Stroke can be ischemic or hemorrhagic. Over 100 diseases are associated with ischemic stroke, making it heterogeneous. It is the most common type of stroke and accounts for 87% of all strokes. Ischemic stroke is further divided into two groups; thrombotic stroke (the formation of clot or plaque in blood vessels within the brain) and embolic stroke (the formation of clot or plaque somewhere else in the body and travels to blood vessel of the brain through blood stream).

Atherosclerosis, arterial dissection, and artery-to-artery embolism are all examples of large vessel disease. The primary small vessel diseases causing lacunar strokes are lipohyalinosis and atherosclerosis. Intracerebral hemorrhage, which can occur deep (basal ganglia, brainstem), cerebellum, or lobar, accounts for about 15% of strokes. About 20% of intracerebral hemorrhages are brought on by macro vascular lesions (vascular malformations, aneurysms, cavernomas), venous sinus thrombosis, or other uncommon causes; these are particularly significant in young patients.

Literature review A systematic and evidence based search of relevant literature was performed by utilizing PubMed and Google Scholar as search engines. Search term for the initial literature review was post-stroke mirror therapy, post-stroke cross education, comparison of mirror therapy versus cross education non paretic limb training, upper limb strength and hand dexterity.

O. van der Groen et al. (2023) studied the Corticospinal and intracortical responses from both motor cortices following unilateral concentric versus eccentric contractions and compared responses to transcranial magnetic stimulation(TMS) in both motor cortices following single sessions of unilateral ECC and CON exercise of the elbow flexor and concluded that These findings suggest that responses after a single bout of exercise may not reflect longer term adaptations.

S. Karamat et al. (2022) compared the effects of task-based mirror therapy and Repetitive Facilitation Exercise on upper limb function in post stroke patient. The study concluded that mirror therapy and repetitive facilitation Exercise both were found to be effective in improving upper limb motor functions of acute stroke patients. However, Mirror therapy has shown significant effects in upper extremity functional index.

Related Conditions & MeSH terms

• Hemiplegia
• Hemiplegia and Hemiparesis
• Paresis

Intervention

Other:
• Cross education
For strength training resistance exercises with a load of 60% of one repetition maximum will be performed targeting the muscle involved in upper limb function. Strength will be measured using the grip strength test/hand held dynamometer. Patients will undergo 45 minute session per day, 3 days per week for 6 weeks.
• Mirror Therapy
Participants will be asked to sit in front of a table of appropriate height with their arms resting on the table and a mirror (35 cm × 35 cm) placed between the patient's arms. The non-affected arm will be placed in front of the mirror and the affected arm will be placed and obscured. Appropriate movement tasks will be selected according to the function of the affected upper limb. This exercise will be performed 45 minutes per day, 3 times per week for 6 weeks

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Action Research Arm Test (For Functional Limitation)	The instrument contains 19 items grouped into 4 subtests; grasp, grip, pinch, and gross motor. Item performance is rated on a 4-point scale (0=unable; 1=partial; 2= abnormal; 3=normal) then item ratings are summed and reported out of 57 points with higher score indicating greater UE function.	Changes from baseline Action Research Arm Test at 3rd week and after 6 weeks
Primary	Fugl-Meyer Assessment. (For Upper extremity function)	The Fugl-Meyer Assessment is the gold standard to assess motor function of post-stroke hemiparesis. The FMA-UE consists of 30 items assessing motor function and 3 items assessing reflex function. The scores most applicable to task performance is given from "0, inability," "1, beginning ability," to "2, normal" (total score range, 0-66).Higher the score more is the independence.	Changes from baseline Fugl-Meyer Assessment at 3rd week and after 6 weeks
Primary	Hand-held dynamometer. (For Upper Limb strength assessment)	This instrument is scored using force produced in kilograms (0-90) or pounds (0-200). The subject is seated with back, pelvis and knees as close to 90 degrees as possible, shoulder is adducted and neutrally rotated, elbow flexed to 90 degrees, and forearm neutral and wrist held between 0-15 degrees of ulnar deviation. Maximum grip is the mean of 3 trails.	Changes from baseline Fugl-Meyer Assessment at 3rd week and after 6 weeks
Primary	Stroke Impact Scale (For hand function)	The Stroke Impact Scale (SIS) is a stroke-specific, self-report, health status measure. It contains 59 items and assesses 8 domains: Strength - 4 items, Hand function - 5 items, ADL/IADL - 10 items, Mobility - 9 items, Communication - 7 items, Emotion - 9 items, Memory and thinking - 7 items, Participation/Role function - 8 items. For each item individual is asked to rate the level of difficulty in past two weeks using the scale;1= extremely difficult, 2= very difficult, 3= somewhat difficult, 4= a little difficult, 5= not difficult at all. On a scale of 0 to 100, with 100 representing full recovery and 0 representing no recovery.	Changes from baseline Fugl-Meyer Assessment at 3rd week and after 6 weeks
