Effect of Mirror Therapy Versus Bilateral Arm Training for Rehabilitation After Chronic Stroke

Recruiting

Phase N/A Results N/A

Trial Description

The study purpose is to compare the efficacy of mirror therapy and bilateral arm training on movement strategies of the affected upper extremity and functional outcome in chronic stroke patients.

Detailed Description

Study background: Approximately 80% of stroke survivors have an upper and/or lower limb impairment (Barker 1997), and impairment of the arm explains up to 50% of the variance in functional limitation after stroke. Brain imaging research using magnetoencephalography found that mirror therapy combined with bilateral arm training could potentially aid stroke rehabilitation by normalizing an asymmetrical pattern of movement-related beta desynchronization in primary motor cortex. However, different neural mechanisms may cause different effect of motor control recovery after the two different approaches, which have yet to be studied. Study purposeļ¼šTo compare the efficacy of mirror therapy and bilateral arm training on movement strategies of the affected upper extremity and functional outcome in chronic stroke patients. Study method: This was a single-blind, randomized, comparative efficacy research. Sixty participants with chronic stroke will be recruited in the occupational therapy clinics at four hospitals and randomly assigned to the mirror therapy and bilateral arm training groups. The intervention will consist of 1.5 hrs/day, 5 days/wk for 4 wks, including 3 days of hospital-based therapy and 5 days of home practice. Primary outcomes were muscular properties (grip strength) and sensorimotor measurements. Secondary outcomes included measures of daily functions to gain insight about movement capabilities. The validity and reliability of all measurements have been proposed. Finally, the Mann-Whitney U test and the Fisher exact test will be used to compare the significant differences between the two approaches. The effect size of dependent variables will be reported also.
