NCT04290377

Brief Summary

The goal of this clinical trial is to evaluate the efficacy of upper extremity rehabilitation using a Brain-Machine Interface (BMI) in individuals with hemiplegia due to stroke. The main questions it aims to answer are:

  • Can BMI-assisted occupational therapy improve the Fugl Meyer Assessment-Upper Limb (FMA-UL) score in chronic stroke participants?
  • How does the effectiveness of BMI-assisted occupational therapy compare to conventional occupational therapy alone? Participants will: Undergo 5 sessions of BMI-assisted occupational therapy in phase 1. Be randomly allocated to either a control group (receiving conventional occupational therapy) or an experimental group (receiving BMI-assisted OT plus conventional OT) in phase 2. Researchers will compare the control group (OT plus OT) and the experimental group (BMI-assisted OT plus OT) to see if there is a significant difference in the change of FMA-UL score between the two groups.

  • +4 more secondary outcomes

Study Arms (2)

Conventional OT + Motor Imagery OT

ACTIVE COMPARATOR

Conventional OT (30 minutes/day) plus Motor Imagery OT (30 minutes/day) for 10 days.

Other: Motor imagery OT

Conventional OT + BMI-assisted Motor Imagery OT

EXPERIMENTAL

Conventional OT (30 minutes/day) plus BMI-assisted motor imagery OT (30 minutes/day) for 10 days.

Device: BMI-assisted motor imagery OT

Interventions

As the goal of the intervention is to promote finger extension in participants who are unable to extend his/her finger due to stroke, the pneumatic glove provides extension assist when appropriate brain activity is present. The brain activity is obtained by Functional Near-Infrared Spectroscopy (fNIRS). Hypothetically, this will repeatedly induce brain activation that is related to finger extension.

Conventional OT + BMI-assisted Motor Imagery OT

In Motor imagery OT, Subjects try to extend their fingers (imagine) without BMI assistance. All other setting is equal to BMI-assisted motor imagery OT.

Conventional OT + Motor Imagery OT
