Spasticity, Muscle, Spinal Cord Injuries
Conditions
Brief summary
The purpose of our study is to evaluate vibrotactile Coordinated Reset (vCR) and its effects on spasticity symptoms in incomplete spinal cord injured patients. vCR will be administered with a device called the Stanford CR Glove. vCR is expected to provide patients with a non-invasive alternative to the most widely used treatments such as oral baclofen and or deep brain stimulation. Patients will be followed for three months and will be asked to come to the lab for clinical testing 4 times during this period. A total of 30 patients will be included in the study.
Interventions
The experimental device, the Stanford CR Glove, is designed to deliver vibratory stimulation to the fingertips of each hand according to a specific pattern, known as vibrotactile Coordinated Reset, which theoretically disrupts abnormal neuronal synchrony and is expected to restore function.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in spasticity with the Modified Ashworth Scale (MAS) at 2 hours, 1 week, 4 weeks, and 12 weeks. | Baseline, 2 hours, 1 week, 4 weeks, and 12 weeks | The MAS is a method of grading muscle spasticity according to a 6-point ordinal scale. In this assessment, spasticity is judged to be present when resistance is encountered during passive muscle stretching. With a score of 0 indicating no increase in muscle flexion and a score on 4 indicating and increase in muscle flexion. Low numeric ratings indicate better outcomes and high numbers indicate worse outcome. |
