4. Pregnant or women who intend to become pregnant or breastfeeding women. Women of child bearing potential are required to use oral contraceptives, condoms, intrauterine device (IUD) diaphragm, spermicide, sexual abstinence or vasectomized partner. Female patients using contraception should continue to use contraception 3- 4 months post injection. Women of childbearing potential are defined as any female who has experienced menarche and who is NOT permanently sterile or postmenopausal. Postmenopausal is defined as 12 consecutive months with no menses without an alternative medical cause.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	12 item Multiple Sclerosis Walking scale (MSWS-12) Improvement	Mean change from baseline in the 12 Item Multiple Sclerosis Walking Scale. The Multiple Sclerosis Walking Scale is a self-assessment scale which measures the impact of MS on walking. It consists of 12 questions concerning the limitations to walking due to MS during the past 2 weeks. Each item can be answered with 5 options, with 1 meaning no limitation and 5 extreme limitation.; A total score can be generated and transformed to a 0 to 100 scale by subtracting the minimum score possible (12) from the patient's score, dividing by the maximum score possible minus the minimum possible (60-12 or 48), and multiplying the result by 100. Walking improvement on the MSWS-12 is indicated by negative change scores	Baseline weeks 12, 16, and 20
Other	Improvement of (MSIS-29) Multiple Sclerosis Impact Scale	Mean change from baseline in the (MISIS-29) Multiple Sclerosis Impact Scale.The MSIS-29 is a 29 item measurement, which assesses the physical and psychological impact of MS on affected individuals; it is a self report questionnaire consisting of 20 and 9 items, respectively. Scores on the individual items are added and then transformed to a 0-100 scale, thereby generating two summary scores (for physical and psychological impact). Higher scores indicate worse health.	Baseline weeks 12,16 and 20
Other	Improvement of Pain Scale	Mean change from baseline in the 0-10 Pain Scale. involves asking the patient to rate his or her pain from 0 to 10 (11 point scale) with the understanding that 0 is equal to no pain and 10 is equal to worst possible pain.; 0 Pain free; Very minor annoyance-occasional minor twinges; Minor annoyance-occasional; Annoying enough to be distracting; Can be ignored if you are really involved in your work, but still distracting,; Can't be ignored for more than 30 minutes.; Can't be ignored for any length of time, but you can still go to work and participate in social activities.; Make it difficult to concentrate, interferes with sleep, you can still function with effort; Physical activity severely limited. You can read and converse with effort. Nausea and dizziness may occur.; Unable to speak, crying out or moaning uncontrollable- pain makes you pass out; Unconscious. Pain makes you pass out.	Baseline weeks 12,16 and 20
Other	Improvement of (MSSS-88) Multiple Sclerosis Spasticity Scale	Mean Change from baseline in the (MSSS-88) Multiple sclerosis Spasticity scale measures patient experience and perception of the impact of spasticity in MS with day-to-day symptoms andduring functional activities over the previous two weeks. It has 88 questions to quantify spasticity for a total score and in eight clinically relevant and stand-alone subscales: muscle stiffness, pain and discomfort,muscle spasms, activities of daily living,walking, body movements, emotional health, and social functioning.This scale has 88 items that are rated on a 4-point scale of 1 (Not at all bothered) through 4 (Extremely bothered).	Baseline weeks 12,16 and 20
Other	Improvement of the Penn Spasm frequency scale	Mean change from baseline in the Penn Spasm frequency scale. The patient evaluates his/her "spasms", quantifying them according to 5 classifications (from 0 to 4).For ratings of 1 or greater, the severity of the spasms is also be evaluated, using a 3 level scale (mild, moderate or severe)	Baseline weeks 12,16 and 20
Other	Improvement from baseline on the Timed 25 foot walk (T25FW)	Mean change from baseline on the Timed 25 foot walk (T25FW) The Timed 25-Foot Walk test is a mobility and function test based on a timed 25-foot walk. An individual will be asked to walk 25 feet on a clearly marked course as quickly and safely as they can.; The time is calculated with a stopwatch, recorded, and the individual is asked to repeat the task immediately, walking back the same distance to the their initial starting point.	Baseline weeks 12,16 and 20
Other	Improvement of Timed up and Go	Mean change from baseline on the Timed up and go. The purpose of the Timed Up and Go test is to identify individuals who are at risk of falling. It can screen for balance and gait problems.; A person is observed as they stand from a sitting position without using their arms for support, then walk 10 feet, turn and return to a chair. Finally, they sit back in the chair without using their arms for support.	Baseline weeks 12,16 and 20
Other	Improvement on the (EDSS) score	Mean change from baseline on the Expanded Disability Status Scale (EDSS) score. is a 20 point ordinal scale ranging from 0 (normal neurological exam) to 10 (dead from MS). From 0-4.0, EDSS is determined by the combination of scores on 7 functional systems. From 4.0-6.0 EDSS is determined by the ability to walk a distance. EDSS 6.0 is the need for unilateral walking assistance. EDSS 6.5 is the need for bilateral walking assistance. Nonambulatory patients are scored EDSS =7.0, with higher number reflecting increasing difficulty with mobility and ability to perform self-care.	Baseline weeks 12,16 and 20
Other	Walking improvement	Change from baseline in speed, cadence, general symmetry, propulsion, stride length using the G-Walk device is a wireless system of inertial sensors composed of a triaxial accelerometer, a magnetic sensor, and a triaxial gyroscope that, when positioned on L5 vertebrae of the spine, it allows for a functional objective gait analysis to be performed. The system extrapolates the data and calculates all the spatial-temporal gait parameters required to perform an assessment or to define a training strategy	Baseline weeks 12,16 and week 20
Primary	Using Dysport to treat lower extremity spasticty in patients diagnosed with Multiple Sclerosis. Improved walking ability and quality of life in 28 patients based on quality of life assessments and patient reported outcomes.	Using Dysport® (abobotulinumtoxin A) to treat patients diagnosed with Multiple Sclerosis with lower extremity spasticity .	20 weeks
Secondary	Mean change from baseline in Modified Ashworth Scale (MAS)	Mean change from baseline in Modified Ashworth Scale (MAS).. The Modified Ashworth Scale issued to grade spasticity. This scale measures the presence of velocity-dependent resistance on a 0 to 4 scale, with zero representing normal muscle tone, and four representing a limb that is fixed in flexion or extension	Baseline week 12, week 16, and week 20
