Vibration + CIMT for Hemiparesis

(CPT Trial)

This trial explores whether adding gentle vibrations to constraint-induced movement therapy (CIMT) can improve hand function more than CIMT alone. CIMT involves restricting the unaffected hand to encourage use of the weakened hand. Participants will wear either a vibrating or non-vibrating watch during therapy sessions. The trial seeks individuals with one-sided arm weakness who can still use the affected arm for basic activities like play and self-care. As an unphased trial, this study provides a unique opportunity to contribute to innovative research that could enhance therapeutic options for improving hand function.

The trial information does not specify whether you need to stop taking your current medications.

Research has shown that using vibration therapy alongside other treatments is generally safe for people recovering from a stroke. One study found that using a vibrating device on the wrist daily for a month was safe for stroke survivors. Another study confirmed the safety of a similar type of vibration therapy over six weeks. These findings suggest that adding vibration to therapy does not cause harm.

Researchers are excited about this trial because it explores an innovative approach to enhancing Constraint-induced Movement Therapy (CIMT) for hemiparesis. Unlike traditional CIMT, which focuses solely on restricting the use of the unaffected limb to improve function in the affected one, this trial introduces a vibrating watch worn on the affected wrist during therapy. The vibration is thought to provide additional sensory feedback, potentially enhancing motor learning and recovery. This novel integration of sensory stimulation could offer a more effective rehabilitation strategy for individuals with hemiparesis, making it a promising development in the field.

Research has shown that vibration therapy can improve movement and reduce muscle stiffness in individuals with nerve-related conditions. One study found that it helped stroke survivors move their arms more effectively. Another study demonstrated improved movement skills and reduced muscle stiffness. In this trial, participants will wear either a vibrating watch or a non-vibrating watch during constraint-induced movement therapy (CIMT). These findings suggest that adding vibration to treatments like CIMT might enhance hand use in individuals with one-sided weakness. While promising, results can vary for each person.⁶⁷⁸⁹¹⁰
