Summary
Participants (n=20) will be identified at routine care visits performed at the Rochester Multiple Sclerosis Center. Eligible participants will have MS by McDonald Criteria,7 and will have a modified Ashworth spasticity rating8 of two or higher in at least one lower extremity muscle group. Participants will be seen at screening, one, and three months, and will be evaluated using the modified Ashworth scale,8 pendulum test,9 toe tapping test,10 manual muscle testing,11 timed 25 foot walk,12 and Multiple Sclerosis Functional Composite.13 The type and severity of any adverse events will be recorded using standard definitions. Participants will be instructed to call between visits to inform the investigators regarding any adverse events they experience. Follow-up will continue until all adverse events resolve or stabilize.
Eligibility Criteria
Inclusion Criteria
- Multiple sclerosis by McDonald Criteria.
- Spasticity. A minimum score of two on the Ashworth spasticity scale in at least one lower extremity muscle group and a total score of at least four in the lower extremity muscles tested.
- Age 18-70.
- Normal renal function (estimated CrCl > 50 ml/min).
- Women of childbearing potential (i.e., those not postmenopausal or surgically sterile) may participate provided that they are using adequate birth control methods (including barrier methods, IUD, and oral contraceptives) for the duration of the study.
- Willing and able to perform all procedures related to the clinical trial and to provide informed consent.
