Dalfampridine and Gait in Spinocerebellar Ataxias
January 8, 2015 updated by: University of Florida
Therapeutic Effect of Dalfampridine on Gait Incoordination in Spinocerebellar Ataxias- A Randomized, Double-blinded, Placebo-controlled, Crossover Clinical Trial
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.

Intervention / Treatment
Detailed 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.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Timed 25 Feet Walking Test (T25FW)
Time Frame: Baseline and 4 weeks after Dalfampridine or placebo
|
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
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Scale of Assessment and Rating of Ataxia (SARA)
Time Frame: Baseline and 4 weeks after Dalfampridine or placebo
|
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
|
Biomechanical Assessment of Gait (BAG)-Stride Length
Time Frame: Baseline and 4 weeks after Dalfampridine or placebo
|
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
