Clinical Trial Summary

Rehabilitation options for stroke survivors who present severe hemiparesis in chronic stages are limited and may end in compensation techniques that involve the use of the less affected arm to achieve some degree of functional independence. Transcranial direct current stimulation (tDCS) is a non-invasive technique that has been used after stroke to promote excitability of the surviving neural architecture in order to support functional recovery. Interestingly, cortical excitability has been reported to increase when tDCS is combined with virtual reality. This synergetic effect could explain the promising results achieved by preliminary experimental interventions that combined both approaches on upper limb rehabilitation after stroke. The objective of this study is to explore the use of these interventions in subjects with severe hemiparesis and to determine its efficacy in comparison to conventional physical therapy

Intervention

Device:
• REACt system
The REACt system is a virtual reality-based paradigm for upper limb rehabilitation that allows for interaction of individuals with restricted movements from active responses triggered when they attempt to perform a movement. The experimental system also provides multisensory stimulation in the visual, auditory, and tactile channels, and transcranial direct current stimulation coherent to the observed movements

Other:
• Physical therapy
Physical therapy included passive and active mobilization of the paretic upper limb. Passive range of motion exercises were provided in those segments where no active movement was detected to meticulously reproduce a range of articular movements and muscle and soft tissue elongation. In case of residual active movement capability, participants were encouraged to perform the movements with the assistance of the therapists

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in the Upper Extremity subscale of the Fugl-Meyer Assessment Scale from baseline to the end of the intervention and from the end of the intervention to one-month after the intervention	The Fugl-Meyer Assessment of Motor Recovery after Stroke evaluates and measures recovery in post-stroke hemiplegic patients in both clinical and research settings. Score range: 0-66	Pre-intervention (within 5 days prior intervention), post-intervention (within 5 days after intervention), one-month follow-up (within 30 to 35 days after the intervention)
Secondary	Change in the Time subscale of the Wolf Motor Function Test from baseline to the end of the intervention and from the end to one-month after the intervention	The Wolf Motor Function Test is a quantitative measure of upper extremity motor ability through timed and functional tasks. Score range: 0-1200	Pre-intervention (within 5 days prior intervention), post-intervention (within 5 days after intervention), one-month follow-up (within 30 to 35 days after the intervention)
Secondary	Change in the Functional ability subscale of the Wolf Motor Function Test from baseline to the end of the intervention and from the end to one-month after the intervention.	The Wolf Motor Function Test is a quantitative measure of upper extremity motor ability through timed and functional tasks. Score range: 0-75	Pre-intervention (within 5 days prior intervention), post-intervention (within 5 days after intervention), one-month follow-up (within 30 to 35 days after the intervention)
Secondary	Change in the Nottingham Sensory Assessment from baseline to the end of the intervention and from the end to one-month after the intervention.	The Nottingham Sensory Assessment is a multi-modal sensory examination that includes tests of tactile sensation (Score range: 0-2) (light, touch, touch localization, temperature discrimination, pinprick sensation, bilateral simultaneous stimulation), kinesthesia (Score range:0-3), and stereognosis (Score range: 0-2)	Pre-intervention (within 5 days prior intervention), post-intervention (within 5 days after intervention), one-month follow-up (within 30 to 35 days after the intervention)
Secondary	Intrinsic Motivation Inventory	The Intrinsic Motivation Inventory is a multidimensional questionnaire structured into various subscales. In this study, this questionnaire was used to assess participant interest/enjoyment, perceived competence, pressure/tension, and value/usefulness measures. Score range for each subscale: 1-7	Post-intervention (within 5 days after intervention)
Secondary	System Usability Scale	The System Usability Scale is a simple ten-item scale that serves as a global assessment of subjective usability. Score range: 0-100	Post-intervention (within 5 days after intervention)
