500 U, I.M. (in the muscle) injection on day 1 of a single treatment cycle.

Experimental: Dysport 1000 U Drug: Botulinum type A toxin (Dysport®)

Primary Outcome Measures :
  1. Change From Baseline in MAS Score in the Primary Targeted Muscle Group (PTMG) [ Time Frame: From Baseline (Day 1) to Week 4 ]
    MAS scale is used to assess muscle tone using a 6-point scale where: 0=No increase in muscle tone, 1=Slight increase in muscle tone manifested by a catch and release or by minimal resistance at the end of the range of motion (ROM) when the part is flexed or extended, 1±Slight increase in muscle tone manifested by a catch followed by minimal resistance throughout the remainder of the ROM, 2=Marked increase in muscle tone through most of the ROM but affected part easily moved, 3=Considerable increase in muscle tone passive movement difficult or 4=Affected part(s) rigid in flexion or extension. The MAS has been derived for analyses as follows: 0=0 ; 1=1; 1+=2; 2=3; 3=4 and 4=5.

Secondary Outcome Measures :
  1. Physician's Global Assessment (PGA) of Treatment Response [ Time Frame: At Week 4 ]
    PGA is a 9-point scale used to assess global overall treatment response by the investigator (-4: markedly worse, -3: much worse, -2: worse, -1: slightly worse, 0: no change, +1: slightly improved, +2: improved, +3: much improved and +4: markedly improved).

  2. Change From Baseline in DAS Score for the Principal Target of Treatment (PTT) [ Time Frame: From Baseline (Day 1) to Week 4 ]

    DAS is a 4-point scale used to determine the extent of functional impairment in 4 functional domains (dressing, hygiene, limb position and pain). DAS scale rating: 0=No disability, 1=Mild disability (noticeable but does not interfere significantly with normal activities), 2=Moderate disability (normal activities require increased effort and/or assistance) and 3=Severe disability (normal activities limited).

    If subject chose 'Hygiene' as PTT the score collected will be between 0 and 3.
