Effect of Using TheraBracelet on Grasping versus Reaching in Poststroke Rehabilitation.

A peripheral sensory stimulation named TheraBracelet has recently been shown to have a potential to improve gross manual dexterity following stroke. Upper limb function requires both reach and grasp. It is unknown whether TheraBracelet affects one more than other. The objective of this study was to determine whether TheraBracelet improves reaching versus grasping. In a pilot randomized controlled trial, persons with stroke received TheraBracelet (treatment) or no stimulation (control) during task practice therapy (n = 6/group). Effects of TheraBracelet on reaching versus grasping were determined using breakdown of movement times in the Box and Block Test video recordings. Improvements in movement times for the treatment compared with control group were more pronounced for grasping than for reaching at both post and follow-up time points. TheraBracelet may be beneficial for persons with grasping deficits. This knowledge can guide clinicians for targeted use of TheraBracelet, resulting in effective implementation of the new treatment.
