NCT05490277

Brief Summary

The purpose of our study is to evaluate Vibrotactile Coordinated Reset stimulation (vCR) and its effects on motor ability within stroke patients. vCR will be administered with a device called the Vibrotactile (VT) Brain Glove. vCR is expected to provide patients with a non-invasive therapy to aid in recovery from a stroke. This study will include a dedicated sham arm that will aid in understanding true treatment effects from vCR.

Outcome Measures

Primary Outcomes (2)

  • Fugl Meyer Assessment of Motor Recovery after Stroke change from baseline, 3 months, 4 months, 7months and 8 months

    The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment. The scale is comprised of five domains and there are 155 items in total. Scoring is based on direct observation of performance. Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform, 1=performs partially and 2=performs fully. The total possible scale score is 226.

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

  • Neuro Quality of Life Upper Extremity Short Form test change from baseline, 3 months, 4 months, 7months and 8 months

    The Neuro quality of life upper extremity short form test measures the functionality of upper extremities. This is a self-report questionnaire that has a Likert scale from 1 to 5, with 5 indicating no difficulties and 1 indicating unable to do. Total possible points are out of 40, with a higher score indicating better upper extremity abilities.

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

Secondary Outcomes (6)

  • Barthel Index for Activities of Daily Living change from baseline, 3 months, 4 months, 7months and 8 months

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

  • Action Research Arm Test change from baseline, 3 months, 4 months, 7months and 8 months

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

  • Timed Up and Go test change from baseline, 3 months, 4 months, 7months and 8 months

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

  • Neuro Quality of Life Lower Extremity Short Form test change from baseline, 3 months, 4 months, 7months and 8 months

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

  • Sensorimotor reaction time task

    This clinical assessment will be done at baseline visit, three month visit, four month visit, seven month visit and eight month visit

  • +1 more secondary outcomes

Study Arms (2)

Active Vibrotactile Coordinated Reset (vCR)

ACTIVE COMPARATOR

Vibrotactile Coordinated Reset delivers vibratory stimulation to the fingertips of each hand. A specific pattern of vibration to each fingertip is delivered which theoretically disrupts abnormal synchrony in the brain.

Device: Active Vibrotactile coordinated reset

Sham Vibrotactile Coordinated Reset (vCR)

SHAM COMPARATOR

Vibrotactile Coordinated Reset delivers vibratory stimulation to the fingertips of each hand. An inactive pattern of vibration to each fingertip is delivered which theoretically will not have the effects of active vCR.

Device: Sham vibrotactile coordinated reset

Interventions

Participants will receive active vibrotactile coordinated reset (vCR) which sends gentle vibrations to the fingertips at a specific pattern. The purpose of the intervention is to test the efficacy of active vCR in comparison to sham vCR.
