Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Summary:
This study aims to investigate the effectiveness of a vibrating splint in improving hand function and reducing spasticity among individuals who have experienced a stroke. Stroke is a major global health issue, often resulting in long-term disability and impairments in the upper limbs. Spasticity, a common complication of stroke, causes stiffness and involuntary muscle contractions, leading to difficulties in performing daily activities.
Current treatment options for spasticity include medications and physical therapy techniques. However, these approaches may have limitations in terms of effectiveness and duration of benefits. Therefore, non-pharmacological interventions are being explored to enhance rehabilitation outcomes.
The hypothesis of this study is that the use of a vibrating splint, which applies mechanical vibrations to the hand muscles, will decrease spasticity and improve hand functionality in individuals with chronic stroke. The vibrations from the splint stimulate the sensory receptors in the skin and muscles, leading to muscle relaxation and improved motor control.
The study will be conducted as a pilot randomized controlled trial, involving participants who meet specific eligibility criteria. The participants will be divided into three arms, with each arm receiving a different intervention. Outcome measures, including assessments of spasticity, range of motion, pain levels, and functional abilities, will be collected before and after the intervention period.
The findings from this study will contribute to the understanding of non-pharmacological approaches in managing spasticity and improving hand function after stroke. If the vibrating splint proves to be effective, it could offer a safe and accessible option for stroke survivors to enhance their recovery and regain independence in daily activities.
This research is essential as it addresses the need for more effective interventions for spasticity management and hand rehabilitation after stroke. By providing valuable insights into the potential benefits of the vibrating splint, this study has the potential to improve the quality of life for individuals who have experienced a stroke and empower them to regain control over their hand movements.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Study Objectives and Questions:
Determine whether adding FMV to anti-spastic splint therapy provides additional benefit for individuals with spasticity after a stroke.
Compare the outcomes of anti-spastic splint therapy, FMV therapy, and a combination of both interventions in individuals with post-stroke spasticity.
Explore participant perceptions regarding the effectiveness, acceptability, and adherence to the interventions.
Study Design and Procedures:
The study is a pilot, multi-center RCT with a single evaluator (evaluator-blind) approach to avoid bias.
Forty-eight participants will be randomly assigned to one of three groups: Arm 1 (anti-spastic splint and FMV), Arm 2 (FMV only), or Arm 3 (anti-spastic splint only).
Interventions will be delivered by trained rehabilitation specialists, including occupational and physical therapists.
Standardized intervention protocols will guide the delivery of FMV and anti-spastic splint therapy for a period of four weeks.
Participant Recruitment:
Participants with chronic post-stroke spasticity are recruited from multiple rehabilitation centers and screened based on specific inclusion and exclusion criteria.
Convenience sampling is used to enroll participants from available populations in the participating centers.
Data Collection and Management:
Baseline and post-treatment evaluations include measurements of spasticity, hand functionality, range of motion, and pain level.
Qualitative interviews will explore participants' experiences with the interventions and their perceptions of the treatments' effectiveness.
Data will be securely stored and anonymized to protect participants' privacy.
Statistical Analysis Plan:
Linear Mixed-Effects Models (LMEM) will be used to assess treatment effects, adjusting for correlation over time within participants.
The safety analysis will involve documenting and summarizing adverse events (AEs) across treatment groups.
The study aims to provide preliminary data on treatment effects and inform the design of future larger RCTs.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Vibration plus anti-spastic hand splint Arm
In this clinical trial, vibration stimulation will be applied to the spastic hand antagonistic muscles using a specific device consisting of a volar anti-spastic hand splint and the arm vibrator. The volar anti-spastic hand splint will be custom-made for each participant at the prosthetic and orthotic clinic, following a standardized protocol. The arm vibrator, designed to fit the arm, will deliver the required vibration parameters. The intervention protocol involves a 30-minute vibration session administered three times weekly for four weeks, accompanied by daily utilization of the custom-made splint for 30 minutes each day.
Vibration plus anti-spastic hand splint
vibration stimulation will be applied to the spastic hand antagonistic muscles using a volar anti-spastic hand splint and the Myovolt Arm vibrator.
Anti-spastic hand splint Arm
In the anti-spastic hand splint arm , participants will be provided with an anti-spastic splint without vibration. Both vibration plus anti-spastic hand splint arm and anti-spastic hand splint arm will adhere to the same splint standard regime and recommendations, which outlines the specific positioning for the splint.
