Measure Description |
Time Frame |
|---|---|---|
|
Change in Gait Speed
Time Frame: Change from baseline at weeks 4, 8, and 12.
|
Time to walk 25 ft as quickly as possible
|
Change from baseline at weeks 4, 8, and 12.
|
|
Change in Walking Endurance
Time Frame: Change from baseline at weeks 4, 8, and 12
|
Distance walked in 6 min when walking at a brisk pace
|
Change from baseline at weeks 4, 8, and 12
|
|
Change in Dynamic Balance
Time Frame: Change from baseline at weeks 4, 8, and 12
|
Score achieved on the four components of the 14-item Mini-Balance Evaluation Systems Test (Mini-BESTest).
The maximum score for each subscale are: anticipatory = 6, reactive postural control = 6, sensory orientation = 6, dynamic gait = 10.
The subscales are added to provide a total score with a maximum of 28.
|
Change from baseline at weeks 4, 8, and 12
|
|
Change in Patient Determined Disease Steps
Time Frame: Change from baseline at weeks 4, 8, and 12
|
A questionnaire with a self-assessment scale of disease status.
The scores range from 0 = normal to 8 = bedridden.
|
Change from baseline at weeks 4, 8, and 12
|
|
Change in Modified Fatigue Impact Scale
Time Frame: Change from baseline at weeks 4, 8, and 12.
|
A questionnaire that assesses the impact of fatigue experienced by persons with MS.
Each of the 21 items is rated from 0 = Never to 5 = Almost always.
The maximum total score = 105
|
Change from baseline at weeks 4, 8, and 12.
|
|
Change in MS Walking Scale-12
Time Frame: Change from baseline at weeks 4, 8, and 12.
|
A 12-item, patient-rated measure of how much MS compromises walking ability.
Each item is rated from 1 = Not at all to 5 = extremely.
The maximum total score = 60.
|
Change from baseline at weeks 4, 8, and 12.
