Study Summary

Following a stroke, individuals experience pain in the affected upper limb (UL) and residual weakness in the UL, which impacts their quality of life and performance of activities of daily living. To overcome these deficits, exercises are a key element to any rehabilitation program and are based on the reorganization capacity of the central nervous system (called neuroplasticity). To optimize the beneficial effects of exercises and potentiate neuroplasticity, non-invasive brain stimulation devices (NIBS) are increasingly used as a complementary therapy post stroke. Among NIBS, a new technique, called cranial nerve non-invasive neuromodulation (CN-NINM), is making its way into stroke rehabilitation since, unlike other NIBS such as tDCS, it allows the generation of a direct flow of neuronal impulses via the stimulation of the tongue. The goal of this project is therefore to investigate CN-NINM to document its feasibility and explore its efficacy at improving motor recovery and reduce pain at the affected UL in chronic stroke patients (> 6 months). CN-NINM will be applied for 20 minutes during each exercise session of the UL (3X/week, 4 weeks). Feasibility data will comprise adherence to CN-NINM, drop out rate and adverse events and UL motor recovery and pain will be assessed before and after the exercise program. At the end of this study, it is expected that it will be feasible to use CN-NINM as an intervention in combination with the exercise program and that it will result in improved motor function and reduced pain in affected UL.
