Clinical Trial Summary

Investigators expect there will be improvement in walking speed and steadiness after taking Dalfampridine, thereby improving activities of daily living and enhancing social and occupational functions for patients with spinocerebellar ataxia.


Description:

Twenty spinocerebellar ataxia patients will be randomized to receive either Dalfampridine or placebo over a total period of 10 weeks. After entering the study, patients will return every 2 weeks for evaluation. After four weeks, intervention will be stopped and patient will enter a 2-week wash out period where they do not take any drug. Then, patients will be given the opposite treatment (Dalfampridine or placebo) and this "crossover" study will be performed for another 4 weeks. Investigators expect there will be improvement in walking speed and steadiness after taking Dalfampridine, thereby improving activities of daily living and enhancing social and occupational functions.

Outcome

Type Measure Description Time frame Safety issue
Primary Change in Timed 25 Feet Walking Test (T25FW) The patient is directed to one end of a clearly marked 25-foot course and is instructed to walk 25 feet as quickly as possible, but safely. The time, in seconds, is calculated from the initiation of the instruction to start and ends when the patient has reached the 25-foot mark. Baseline values are recorded twice. One was at the beginning of the intervention. The second was 2 weeks after washout period and before the second intervention. Baseline and 4 weeks after Dalfampridine or placebo No
Secondary Change in Scale of Assessment and Rating of Ataxia (SARA) Scale for the assessment and rating of ataxia (SARA) is a clinical scale that is based on a semiquantitative assessment of cerebellar ataxia on an impairment level. SARA has 8 items that are related to gait, stance, sitting, speech, finger-chase test, nose-finger test, fast alternating movements and heel-shin test. SARA score ranges from 0 to 40, with higher scores indicating more severe disease. Baseline and 4 weeks after Dalfampridine or placebo No
Secondary Biomechanical Assessment of Gait (BAG)-Stride Length Biomechanical Assessment of Gait is a sensitive, quantitative movement analysis system. Stride length was analyzed. Baseline values are recorded twice. One was at the beginning of the intervention. The second was 2 weeks after washout period and before the second intervention. Baseline and 4 weeks after Dalfampridine or placebo No
