Active Somatosensory Exercise for Chronic Stroke

Summary

The current work aims to examine whether the proposed rehabilitation training or exercise will eventually yield improvements in both motor and somatosensory aspects at one goal. Here, the word 'somatosensory' refers to bodily sensations associated with proprioception or kinesthesia, not the sensation of touch, pain, and temperature. The study focuses on upper limb retraining for community-dwelling stroke survivors using a robotic device. At the end of training, both movement accuracy and somatosensory acuity in chronic stroke survivors are presumed to improve, and such paradigm is expected to provide reliable benefits as compared to conventional intervention alone.

Conditions

Interventions

BEHAVIORAL

Active somatosensory training

Patients in the experimental group will be required to move the robotic handle using their paretic arm from the start position to a visual target shown on screen. However, patients' paretic arm will be occluded from vision throughout the training session. They will make the reaching movement by depending on their proprioception of the arm position in space, without relying too much on the vision of their arm. Haptic guidance will be provided as somatosensory cues while participants are actively moving. Positive reinforcement will also be given for each successful movement that reaches the target in the form of a pleasant audio tone, visual feedback, and a running score. Assessment will be performed before and after the completion of the whole 15 training sessions.

BEHAVIORAL

Motor-based training

Patients in the control group will also be required to propel the robotic handle using their paretic arm to a target location. This training covers the same centre-out reaching movements but without any emphasis on proprioception, where the view of the paretic arm will not be occluded. However, no haptic guidance will be provided during the reaching movement. Positive reinforcement will still be given to inform the participants of their trial outcomes. Assessment will be performed before and after the completion of the whole 15 training sessions.
