ISRCTN - ISRCTN22743806: Self-directed upper limb rehabilitation following stroke

Plain English Summary

Background and study aims
In traditional motor rehabilitation training, patients practice repetitive limb movements aimed at improving motor function with the help of physical therapists. However, this training paradigm requires extensive training periods for patients and intensive labor for therapists. We aimed to build an EEG-based active engagement monitoring system that can be applied to various motor task of stroke patients.

Who can participate?
Patients aged 18 to 70 years old who have suffered their first stroke

What does the study involve?
Participants will be required to perform three simple motor tasks whilst brain activity is monitored using EEG equipment.

What are the possible benefits and risks of participating?
Benefit : contributing to research that may support the rehabilitation for the stroke in the future
Risk : No risks by executing three motor task(motor execution by themselves(Active task) or robot assist(Passive task)/ by imaging motor task (MI task)

Where is the study run from?
Samsung Medical Center, South Korea

When is the study starting and how long is it expected to run for?
January 2013 to August 2014

Who is funding the study?
The Korea Institute of Science and Technology (KIST), South Korea

Study hypothesis

The present study aimed to gauge patient engagement during rehabilitation training using an EEG-based BCI. We hypotheses that information related to motor task engagement can be extracted from distinct neural activity patterns associated with each motor task.

Intervention

In order to obtain the characteristics of brain networks of chronic stroke patients during upper limb movements for rehabilitation, participants performed grasp movements with the affected hand by collecting their EEG signals. The haptic device in the experiment was controlled by a DSP processor, and it was synchronized with a stimulation program by FlashTM. This stimulus of haptic was connected to EEG System (sampling rate: 2048 Hz; Active-two, BiosemiTM, Amsterdam, Netherlands).

The experimental protocol included the following three motor tasks: an active task to be executed by a voluntary movement; a passive task to be executed using a robotic device; and a motor imagery task in which participants were instructed to imagine their movement without any physical movement. Each task involved 42 trials.

For each trial, participants fixed their gaze on the monitor for 2 or 3 s, after which they performed the motor task for 2 s after the visual and auditory cues. Participants maintained their grasping movement for 1 s, after which they were asked to release the handle while the robotic device returned it back to its starting position
