Brief summary
Background and Study Aims Stroke is a leading cause of long-term disability worldwide, affecting millions of individuals each year. After experiencing a stroke, many patients face challenges with their upper limbs, resulting in difficulties in performing daily activities. This study aims to evaluate a new rehabilitation device designed to assist stroke patients with hemiparesis (weakness on one side of the body) in improving their upper limb function. The goal is to determine if this device can effectively support recovery while providing an affordable and accessible option for rehabilitation. Who Can Participate? This study is open to adults aged between 18 and 70 years, regardless of sex. To participate, individuals must have a confirmed diagnosis of hemiplegic stroke, which means they must experience weakness in one side of the body. Participants should have had their stroke within the last 12 months and must be able to follow simple commands. Those with cognitive impairments, other neurological disorders, certain orthopedic conditions affecting the upper limb, or active skin issues will not be eligible. What Does the Study Involve? Participants in this study will be randomly assigned to two groups: one group will use the new rehabilitation device, while the other will receive conventional occupational therapy. Both groups will undergo an assessment before and after the intervention to measure their improvement in upper limb function. The device encourages exercises that are essential for fostering movement recovery, while the conventional therapy focuses on traditional rehabilitation methods. Participants will have their upper limb function evaluated through established assessment tools to gauge progress. What Are the Possible Benefits and Risks of Participating? By participating in this study, individuals may experience improvements in their upper limb function, leading to increased independence and enhanced quality of life. Additionally, participants will contribute to valuable research that could improve rehabilitation strategies for future stroke patients. While the rehabilitation device is designed to be safe, some individuals may experience mild discomfort or fatigue from the exercises. However, serious side effects are rare. Participants are encouraged to discuss any concerns with the research team. Where Is the Study Run From? The study is being conducted at New Taipei Municipal TuCheng Hospital in Taiwan, specifically in the rehabilitation ward, where trained medical professionals oversee the research process. When Is the Study Starting and How Long Is It Expected to Run For? The study commenced in September 2023 and is expected to continue through November 2024. This timeline allows for recruiting participants and thorough data collection to assess the device's effectiveness. Who Is Funding the Study? This study does not have external funding and is being conducted independently by the researchers involved. All costs associated with the study, including participant care and device usage, are covered by the resources of the conducting institution. Who Is the Main Contact?

Interventions
DEVICENovel UE rehabilitation device training
The novel UE rehabilitation device training includes the single-joint exercise and dual-joint exercise, each performed 20 repetitions per set, for a total of 5 sets with 30-second rest intervals between sets.
OTHERThe UE functional training
The UE functional training focuses on the affected arm, incorporating exercises such as push-pull boxes (standing or seated), alternating push-pull boxes, and hand-crank exercises.

Intervention model description
An investigator analyzed inclusion and exclusion criteria and assigned participants to one of the groups. Participants were randomly allocated to either the experimental group or the control group. Randomization and group allocation was performed by a research assistant using a computer-generated randomization sequence to ensure unbiased allocation. Each intervention was conducted over a 3-week period, consisting of 10 to 15 sessions.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fugl-Meyer Assessment for Upper Extremity | Outcome measurements were performed at three stages: before and after (immediately following the final session) the intervention. | This assessment captures motor recovery across four specific domains: Part A (proximal upper limb-shoulder, elbow, and forearm), Part B (wrist), Part C (hand), and Part D (coordination and speed). The full scale ranges from 0 to 66 and the higher scores represent the better outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Brunnstrom stage | Outcome measurements were performed at three stages: before and after (immediately following the final session) the intervention. | The Brunnstrom scale classifies motor recovery post-stroke into six stages, ranging from flaccid paralysis (Stage I) to near-normal voluntary control (Stage VI), and the higher stage represent the better outcome. |
| Modified Ashworth scale | Outcome measurements were performed at three stages: before, during (after the 5th training session), and after (immediately following the final session) the intervention. | This scale assesses the severity of muscle spasticity by quantifying resistance to passive movement on a scale from 0 (no increase in tone) to 4 (rigid in flexion or extension) and the higer scores represent the worse outcome. |
