Brief Summary

In this study, the investigators will (1) examine immediate and long-term effects of MT priming with task-specific training versus MT-priming with impairment-oriented training, relative to a dose-matched control therapy on motor function, arm activities, quality of life, etc; (2) provide comprehensive evaluations based on the ICF model to identify the specific benefits of MT-priming regimens; and (3) explore demographic and clinical characteristics of participants that may predict treatment outcomes.

Detailed Description

Stroke is one of the major causes of long-term disability. Most stroke survivors suffer from arm paresis even in the chronic phase. There is a need to develop novel strategies to augment therapeutic efficacy in stroke rehabilitation. One potential method to enhance treatment efficacy is through the "priming" technique. Among all priming techniques, mirror therapy (MT) has been proposed to be a promising method to augment effects of motor re-training. The investigators propose a 3-year research project to determine the effects of MT-priming on augmenting stroke interventions. The investigators select two types of evidence-based neurorehabilitation, the task-specific training and the impairment-oriented training, to be primed by MT based on their unique treatment benefits on restoring arm ability. In addition, the investigators will provide customized home practice corresponding to each type of interventions. Specifically, the investigators will (1) examine immediate and long-term effects of MT priming with task-specific training versus MT-priming with impairment-oriented training, relative to a dose-matched control therapy on motor function, arm activities, quality of life, etc; (2) provide comprehensive evaluations based on the ICF model to identify the specific benefits of MT-priming regimens; and (3) explore demographic and clinical characteristics of participants that may predict treatment outcomes.

Arm && Interventions

Group	Intervention	Description
Control therapy	Control therapy	The control group will receive therapeutic training equivalent in duration to the two experimental groups. The control intervention will include practice of gross/fine motor activities, training of activities of daily living, practice to increase range of motions, muscle strengthening, as well as use of adaptive or compensatory technique to alleviate functional deficits. After that, the contents of home practice will be designed corresponding to treatment principles of the clinic-based intervention.
Mirror therapy priming with impairment-oriented training	Mirror therapy priming with impairment-oriented training	In the regimen, participants will perform MT first followed by impairment-oriented training. After completion of MT, participants will practice impairment-oriented training that emphasizes on restoration of movement. After that, the contents of home practice will be designed corresponding to treatment principles of the clinic-based intervention.
Mirror therapy (MT) priming with task-specific training	Mirror therapy (MT) priming with task-specific training	In the regimen, participants will perform MT first followed by task-specific training. After completion of MT, participants will practice task-specific training that emphasizes on restoration of essential skills for daily activities. After that, the contents of home practice will be designed corresponding to treatment principles of the clinic-based intervention.

Primary Outcome Measures

Name	Time	Method
Change from Baseline Motor Activity Log (MAL) at 6 weeks, and 18 weeks	Baseline, 6 weeks and 18 weeks	The MAL is a subjective outcome measure of an individual's real life functional upper limb performance. The MAL is administered by semi-structured interview to determine (a) how much (Amount of Use - AOU), and (b) how well the individual uses his upper limb (Quality of Movement - QOM) in real life.
Change from Baseline Fugl-Meyer Assessment (FMA) at 6 weeks, and 18 weeks	Baseline, 6 weeks, and 18 weeks	The upper-extremity subscale of the FMA will be used to assess motor impairment. FMA contains 33 items (scale 0-66). The higher summed score means the greater recovery of motor impairment.

Secondary Outcome Measures

Name	Time	Method
Change from Baseline Stroke Impact Scale Version 3.0 (SIS 3.0) at 6 weeks, and 18 weeks	Baseline, 6 weeks, and 18 weeks	The SIS 3.0 is a stroke-specific health-related quality of life instrument. It consists of 59 items assessing 8 domains (i.e., strength, hand function, activities of daily living/instrumental activities of daily living, mobility, communication, emotion. memory and thinking and participation). Items are rated on a 5-point Likert scale, with lower scores indicating greater difficulty in task completion during the past week.
Change from Baseline Nottingham Extended Activities of Daily Living Scale (NEADL) at 6 weeks, and 18 weeks	Baseline, 6 weeks and 18 weeks	The NEADL is a postal questionnaire to monitor the level of ADL disability in patients discharged into the community after rehabilitation. The tool assesses 21 activities within four categories: mobility, kitchen activities, domestic activities, and leisure activities. It provides an extended ADL score that is highly correlated with more complex, self-reported interviewer-administered measures of disability.
Change from Baseline Chedoke Arm and Hand Activity Inventory (CAHAI) at 6 weeks	Baseline and 6 weeks	The CAHAI measures arm and hand functions on 13 actual bilateral tasks on a 7-point scale (1 to 7). The properties of the CAHAI were studied, showing great interrater reliability and convergent and discriminant cross-sectional validity.
Change from Baseline Wolf Motor Function Test (WMFT) score at 6 weeks	Baseline and 6 weeks	The WMFT quantifies the motor functions of the upper limbs through timed and functional tasks.
Change from Baseline Grip and Pinch strength at 6 weeks	Baseline and 6 weeks	The Jamar Plus Digital Hand Dynamometer (Patterson Medical, Warrenville, IL, USA) was provided for measuring grip and pinch strength. Unilateral grip/pinch and bilateral grip/pinch are included.
