Clinical Trial Summary

Stroke can lead to weakness and spasticity in the arm or hand. The purpose of this study is to optimize the design of gentle vibratory stimulation delivered to the hands of individuals with chronic stroke, and explore the effect on range of movement and spasticity.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 35
• Est. completion date: December 31, 2022
• Est. primary completion date: December 31, 2022
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years and older

Eligibility

Inclusion Criteria:

• Age 18 and older.

• diagnosis of stroke with upper extremity spasticity or other movement deficits that affect strength and range of movement.

• willing to participate in the vibrotactile stimulation sessions for consecutive days and willing to return for follow up visits as needed for the PHASE in progress.

• able to provide informed consent.

Exclusion Criteria:

• Patients with severe contracture that precludes Modified Ashworth Score (MAS) testing.

Related Conditions & MeSH terms

• Hemorrhagic Stroke
• Ischemic Stroke
• Muscle Spasticity
• Spasticity as Sequela of Stroke
• Stroke
• Stroke Hemorrhagic
• Stroke, Ischemic

Intervention

Device:
• Vibration pattern
Vibration patterns applied to the affected limb based on pilot study results.
• No vibration
These patients will wear a glove with a blinking light instead of feeling vibrations.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Change in Modified Ashworth at 12 Weeks	Modified Ashworth Scale (from https://www.sralab.org/rehabilitation-measures/ashworth-scale-modified-ashworth-scale). Lower Modified Ashworth scale values indicate a better outcome.; Measures spastic hypertonia by manually moving an affected joint at set velocities.; Scores: 0 (0) - No increase in muscle tone; 1 (1) - Slight increase in muscle tone, manifested by a catch and release or by minimal resistance at the end of the range of motion when the affected part(s) is moved in flexion or extension; 1+ (2) - Slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the ROM (range of movement) 2 (3) - More marked increase in musce tone through most of the ROM, but affect part(s) easily moved 3 (4) - Considerable increase in muscle tone passive, movement difficult 4 (5) - Affected part(s) rigid in flexion or extension	Change from Baseline Modified Ashworth at 12 weeks
