Multi-mode Stroke Rehabilitation System: Development and Validation of Clinical Efficacy

A Novel, Digital, and Interactive Multi-mode Stroke Rehabilitation System of Arm and Hand: Development and Validation of Clinical Efficacy

The specific study aims will be:

1. To develop the novel, digital, and interactive MSR system of arm and hand with integrated digital action observation therapy (AOT) and mirror therapy (MT).
2. To pilot usability testing for examining the feasibility of this new MSR system from the users' experiences and feedback.
3. To examine the treatment effects of digital AOT, digital MT and a control intervention in patients with stroke by conducting a randomized controlled trial.
4. To identify who will be the possible good responders to digital AOT and MT based on their baseline motor function and mental imagery abilities.

Study Overview

• Status: Completed
• Conditions: Stroke; Cerebrovascular Disorders; Central Nervous System Diseases
• Intervention / Treatment: Behavioral: Digital Action Observation Therapy (Digital AOT); Behavioral: Digital Mirror Therapy (Digital MT); Behavioral: Conventional Occupational Therapy

Detailed Description

Phase I: Multi-mode stroke rehabilitation (MSR) System Development & Usability Testing

Ten patients with stroke and 4 certified occupational therapists were recruited in this phase I study. During the pilot testing, each stroke patient will try to use each training mode of digital AOT and MT by the assistance of the therapist. At the end of the pilot testing, the patients and the therapists will be asked to complete the System Usability Scale and a self-designed questionnaire to assess the user experience and perspective about this new MSR system and their view of its suitability for stroke patients.

Phase II: Validation of Clinical Treatment Efficacy

This three-arm, single-blind, randomized controlled trial will investigate the treatment effects among the 3 groups of digital AOT, digital MT, and dose-matched control intervention. An estimated 60 patients with stroke will be recruited to participate in this phase II study. Each participant will receive a total of 15 training sessions (60 minutes per session) for 3 to 4 weeks. Clinical outcome measures will be conducted at baseline, immediately after treatment (the fourth week), and at 1 month follow-up after treatment.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Digital Action Observation Therapy (Digital AOT); The common categories of motor actions and tasks will be selected and included in this group: (a) active range of motion (AROM) exercises, (b) reaching movement or object manipulation, and (c) upper-limb functional tasks.	Behavioral: Digital Action Observation Therapy (Digital AOT); The participants will be asked to observe videos and then practice what the participants observed.
Experimental: Digital Mirror Therapy (Digital MT); The common categories of motor actions and tasks will be selected and included in this group: (a) active range of motion (AROM) exercises, (b) reaching movement or object manipulation, and (c) upper-limb functional tasks.	Behavioral: Digital Mirror Therapy (Digital MT); The participants will observe the real-time self-recorded visual illusion, and move their upper limbs as could as possible.
Active Comparator: Conventional Occupational Therapy; The common categories of motor actions and tasks will be selected and included in this group: (a) active range of motion (AROM) exercises, (b) reaching movement or object manipulation, and (c) upper-limb functional tasks.	Behavioral: Conventional Occupational Therapy; The participants will receive upper-limb training without providing videos for observing neither providing them mirror illusions of movements.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change scores of Fugl-Meyer Assessment	The upper-limb subsection of Fugl-Meyer Assessment is a measure with sound psychometric properties to evaluate motor impairments.	baseline, 4 weeks, 2 months
Change scores of Movement Imagery Questionnaire-Revised, Second Edition	The Movement Imagery Questionnaire-Revised, Second Edition is a 14-item questionnaire with sound reliability and validity to evaluate the ability of motion imagination in patients with stroke.	baseline, 4 weeks, 2 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change scores of Chedoke Arm and Hand Activity Inventory	The Chedoke Arm and Hand Activity Inventory is a reliable and validated measure to assess the independence of stroke patients to perform activities of daily living with an affected upper limb.	baseline, 4 weeks, 2 months
Change scores of Box and Block Test	The Box and Block Test is a tool with sound reliability and validity to evaluate hand dexterity of stroke patients.	baseline, 4 weeks, 2 months
Change scores of Revised Nottingham Sensory Assessment	The Revised Nottingham Sensory Assessment is a standardized measure with good reliability to assess sensory function in patients with stroke.	baseline, 4 weeks, 2 months
Change scores of Barthel Index	The Barthel Index is a validated tool designed to measure activities reflecting the daily living independence.	baseline, 4 weeks, 2 months
Change scores of Motor Activity Log	The Motor Activity Log is a semi-structured interview with good psychometric properties to assess the level of use of affected upper limb in 30 main activities of daily living.	baseline, 4 weeks, 2 months
Change scores of the health state of EQ-5D-5L	The questionnaire of EQ-5D-5L contains 5 dimensions, including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression, and uses a 5-point Likert scale scored from 1 (no problem) to 5 (unable to/extreme problems); whereas, the numerical description of 5 dimensions represents the health state.	baseline, 4 weeks, 2 months
