- Change in MAS Score in the Gastrocnemius-soleus Complex (GSC) at the Ankle Joint of the (Most) Affected Lower Limb [ Time Frame: Change from baseline to Week 4 ]The MAS is a 6-point scale which measures the intensity of muscle tone by measuring the resistance of the muscle to passive lengthening or stretching. Investigator will grade muscle tone in the GSC from 0 (no increase in tone) to 4 (affected parts rigid in flexion or extension).
- Physician's Global Assessment (PGA) of the Treatment Response. [ Time Frame: Week 4 ]PGA Scale of the Treatment Response: Global assessment of treatment response assessed by asking the Investigator the following question: "how would you rate the response to treatment in the subject's lower limb(s) since the last injection?" Answers will be made on a 9 point rating scale (-4: markedly worse, -3: much worse, -2: worse, -1: slightly worse, 0: no change, +1: slightly improved, +2: improved, +3: much improved, +4: markedly improved).
- Goal Attainment Scale (GAS) Score [ Time Frame: Week 4 ]GAS is a functional scale used to measure progress towards individual therapy goals. Individual goals defined for each subject by the physician, and the child's parents (caregiver) where applicable, prior to treatment. Post-baseline, the GAS for each goal rated using a defined scale (-2: Much less than expected outcome, -1: somewhat less than expected outcome, 0: expected outcome, 1: somewhat more than expected outcome, and 2: Much more than expected outcome).
