Brief Summary

This comparative efficacy study will be based on a 3-armed controlled trial: bilateral robotic priming combined with bilateral arm training (bilateral RT+BAT), bilateral robotic priming combined with mirror therapy (bilateral RT+MT), and the control intervention (bilateral RT+IOT). The goal of this 4-year project is to provide scientific evidence of the comparative efficacy research of hybrid interventions based on unilateral vs. bilateral approach to upper limb rehabilitation in subacute and chronic stroke.

Detailed Description

This proposed research fits in the NHRI research priority 4-1 by addressing innovative treatment strategies for stroke that is in desperate need of scientific scrutiny. Stroke is one of the major medical conditions that lead to long-term disability and causes heavy health care and financial burden. Advances in clinical and translational neurosciences have led to the new development of stroke rehabilitation. Current stroke rehabilitation programs such as robotic therapy, mirror therapy, and bilateral arm training are bilateral approaches to intensive practice based on the tenet of practice-dependent neuroplasticity. Bilateral robotic therapy can potentially be a movement-based priming technique to promote rebalancing of cortical excitability and create an enriched neuroplastic environment by priming the brain to facilitate motor and functional recovery. This proposed research project will: (1) examine the effects of bilateral robotic priming combined with bilateral arm training approach versus bilateral robotic priming combined with mirror therapy, relative to the control intervention approach (bilateral robotic priming combined with impairment-oriented training) on sensorimotor function, daily function, self-efficacy, quality of life, and motor control strategy in patients with stroke, (2) investigate the 3-month retention effects of robotic priming combined with contemporary rehabilitation approaches (i.e., bilateral arm training and mirror therapy) and the control intervention, and (3) identify the potential predictors of functionally relevant changes after therapy.

Primary Outcome Measures
NameTimeMethod
Change from Baseline ABILHAND Questionnaire at 6 weeks, and 18 weeksBaseline, 6 weeks, and 18 weeks

The ABILHAND Questionnaire will be used to evaluate the ability of the upper limb in functional activities. ABILHAND contains 23 items (scale 0-69). The higher average score means the greater recovery of the ability of the upper limb in functional activities.

Change from Baseline Stroke Impact Scale Version 3.0 (SIS 3.0) at 6 weeks, and 18 weeksBaseline, 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 Fugl-Meyer Assessment (FMA) at 6 weeks, and 18 weeksBaseline, 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
NameTimeMethod
Change from Baseline Functional Independence Measure (FIM) at 6 weeksBaseline and 6 weeks

The FIM consists of 18 items (scale 18-126) grouped into 6 subscales measuring self-care, sphincter control, transfer, locomotion, communication, and social cognition ability. The higher summed score means the greater recovery of functional independence.

Change from Baseline Possible adverse response at 6 weeksBaseline and 6 weeks

The vertical numerical rating scale supplemented with a faces rating scale (NRS-FRS) and a self-reported assessment will be provided to evaluate adverse effects on fatigue and pain severity, respectively. Both assessments using 11-point scale (0 = no fatigue/pain to 10 = worst possible fatigue/pain) will be applied.

Change from Baseline Activity level as evaluated by actigraphy at 6 weeksBaseline and 6 weeks

We will use the ActiGraph GX3 accelerometers (ActiGraph, Shalimar, FL, USA) to quantitatively measure the amount of use outside the laboratory settings. The accelerometer will record the number of moves each minute, and the average counts of move per minute will be calculated as the primary outcome measure.

Change from Baseline Chedoke Arm and Hand Activity Inventory (CAHAI) score at 6 weeksBaseline and 6 weeks

The CAHAI quantifies the bilateral motor functions of the upper limbs through and functional tasks.

Change from Baseline Goal Attainment Scaling (GAS) at 6 weeks.Baseline and 6 weeks

The GAS will be used for measurement the achievement of each participant's expectation in the course of intervention. The individual intervention goals related to daily activity will be negotiated by the therapists and participants. For the goals potentially achievable and not overly ambitious, each goal will be rated on a 5-point ordinal scale with the level of attainment captured. The importance and the difficulty for each goal will be scored also based on a 3-point ordinal scale (1 to 3). The overall GAS score will be calculated by a following formula and a GAS summed score larger than 50 refers to an above-expected performance.

Change from Baseline Wolf Motor Function Test (WMFT) score at 6 weeksBaseline and 6 weeks

The WMFT quantifies the motor functions of the upper limbs through timed and functional tasks.

Change from Baseline Stroke Self Efficacy Questionnaire (SSEQ) at 6 weeksBaseline and 6 weeks

The SSEQ will be used to measure participants' confidence in functional performance from stroke. It consists of 13 items (scale 0-130). A higher summed score (maximum score indicates higher self- efficacy in functional performance from stroke.

Change from lateral pinch strength at 6 weeksBaseline and 6 weeks

Lateral pinch strength will be used for measurement of muscle strength of the affected hand. The higher score means the greater recovery of muscle strength on the pinch strength.

Change from Baseline Revised Nottingham Sensory Assessment (rNSA) at 6 weeksBaseline and 6 weeks

The rNSA will be used to evaluate changes in sensation. The rNSA using a 3-point or 4-point scale contains 72 items (scale 0-151) and is divided into tactile sensation, proprioception, and stereognosis subscales. The higher summed score means the greater recovery of sensory impairment.

Change from Baseline Medical Research Council scale (MRC) at 6 weeksBaseline and 6 weeks

MRC will be used for measurement of muscle strength of the affected arm. MRC contains 8 items (scale 0-40). The higher summed score means the greater recovery of muscle strength of the affected arm.
