The Modified Ashworth scale measures resistance during passive soft-tissue stretching. Spasticity is graded on a scale of 0 (no increase in muscle tone) to 4 (affected part rigid in flexion or extension). The highest score (flexion or extension), for the lower extremities only, was used for each subject. The change was calculated by taking the Week 7 score and subtracting the Week 0 score. A negative result indicates a decrease in spasticity and correlates to a better outcome.

Population: Only 28 subjects completed the study through the Wk 7 visit; Of these 28 subjects, only 27 subjects had Ashworth assessments at both the Week 0 and Week 7 study visits and were able to be analyzed for this outcome measure.

The AI is a 9-point rating scale used to assess mobility by evaluating the time and degree of assistance required to walk 25 feet. Scores range from 0 (asymptomatic, fully active) to 9 (restricted to wheelchair, unable to transfer self independently). Lower scores represent a better outcome for MS patients. For this study, the AI score was based on the results of the 25 Foot Walk test, also performed at the study visit. The change was calculated by taking the Week 3 score and subtracting the Week 0 score. A negative result for this outcome indicates an improvement in ambulation and correlates to a better outcome.

Population: Only 28 subjects completed the study through the Wk 7 visit; 2 subjects who discontinued early (AE and withdraw by subject) were active at the Wk 3 visit and were included in the Wk 3 analysis; 27 total subjects had Ambulation Index assessments at both the Week 0 and Week 3 study visits and were able to be analyzed for this outcome measure.

A modified servo-controlled torque motor system (Lido WorkSet II) was designed for this study to analyze the resistance to passive movement of the knee. It determines the amount of torque required to move the knee joint (without voluntary resistance) at high velocities (up to 200 degrees per second) and at slow velocities (as low as 10 degrees per second). The slow displacement torque is a measure of the passive resistance to movement (from the connective tissue and the non-contracting muscle) and the rapid displacement torques are the sum of the passive and active (involuntary) resistance. The active (involuntary) resistance is the result of the stretch reflex and correlates well with the clinical assessment of spasticity. The change was calculated by taking the value at Week 3 and subtracting the value at Week 0. A negative result indicates a decrease in the torque measured and correlates to a decrease in spasticity and a better outcome.

Population: Only 28 subjects completed the study through the Wk 7 visit; 2 subjects who discontinued early (AE and withdraw by subject) were active at the Wk 3 visit and were included in the Wk 3 analysis; only 25 total subjects had Lido assessments at both the Week 0 and Week 3 study visits and were able to be analyzed for this outcome measure.

Single digits are presented every 3 seconds and the patient must add each new digit to the one immediately prior to it. The test score is the number of correct sums given (out of a possible 60) in each trial. There are 2 test forms, A and B. The forms were alternated and at least 1 practice test (10 sums) was performed prior to each trial. The change was calculated by taking the Week 3 score and subtracting the Week 0 score.

The EDSS is a method of quantifying disability in MS patients and monitoring changes in the level of disability over time. The EDSS quantifies disability in 7 functional systems (FS): visual, brainstem, pyramidal, cerebellar, sensory, bowel and bladder, and cerebral, and includes a measure of ambulation. Neurostatus version 10/2002 was used for this study. The FS Vision score is determined by a 7-point scale, with 0 being the lowest (normal) and 6 being the highest (grade 5 plus maximal visual acuity of better eye of 20/60 (0.3) or less). Higher values indicate more impaired vision. The change was calculated by taking the Week 3 score and subtracting the Week 0 score. A negative result indicates an improvement in vision and correlates to a better outcome.

The SF-36 is a 36-item scale developed as a generic health status measure. It is a part of the MS Quality of Life Inventory. It can be reported as 2 summary scales - the Physical and Mental components. The scale is measured from 0 -100. The scale is set up so that a higher score indicates better health. The change was calculated by taking the Week 3 score and subtracting the Week 0 score. A positive result indicates an improvement in health status and correlates to a better outcome. A negative result indicates a decline in health and correlates to a worse outcome.
