Least Squares Mean Change From Baseline to Week 4 in the MAS Score in the Gastrocnemius-soleus Complex (GSC) (Knee Extended) [ Time Frame: Baseline and Week 4 ]
Muscle tone in the treated limb was assessed by MAS in the GSC (with the knee extended) at baseline, at Weeks 1, 4 and 12, at discretionary visits at Weeks 16, 20 and 24, and at end of study. The MAS consists of 6 grades: 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)), 1+ (slight increase in muscle tone, manifested by a catch, followed by minimal resistance throughout the remainder (less than half) of the ROM), 2 (more marked increase in muscle tone), 3 (considerable increase in muscle tone) or 4 (affected part(s) rigid in flexion or extension), and can be applied to muscles of both the upper and lower limbs. The least squares mean change from baseline at Week 4 is reported.

  • Physician's Global Assesment (PGA) of Treatment Response at Week 4 [ Time Frame: At Week 4 ]
    An assessment of overall treatment response was conducted at Weeks 4 and 12, and discretionary visits at Weeks 16, 20 and 24 and at end of study by an investigator who had not assessed the MAS. The investigator rated the response to treatment in the subject's lower limb after injection of Dysport® relative to the status at the baseline. Answers were 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. The mean PGA score at Week 4 is reported.
  • Least Squares Mean Change From Baseline to Week 4 in Comfortable Barefoot Walking Speed [ Time Frame: Baseline and Week 4 ]

Evaluations were made barefoot, without walking aids, at baseline and Weeks 1, 4 and 12 and discretionary visits at Weeks 16, 20 and 24 and at end of study. The least squares mean change from baseline at Week 4 is reported.

  • Least Squares Mean Change From Baseline in the Tardieu Scale in the GSC (Knee Extended) at Weeks 1, 4 and 12: Angle of Arrest (XV1), Angle of Catch (XV3) and Spasticity Angle (X) [ Time Frame: Baseline and Weeks 1, 4 and 12 ]
    The Tardieu Scale in the GSC was used to assess spasticity with the knee extended. Assessments were made at slow (V1) and fast (V3) speeds of stretch. Slow speed of muscle stretch measures the range of passive motion. During a slow stretching movement, the examiner determines the angle of movement arrest (XV1), either due to subject discomfort or a mechanical resistance. The same movement is repeated at a fast speed to determine the angle of catch and release (XV3). The spasticity angle (X) was calculated as the difference between XV1 and XV3. The Tardieu Scale ratings were made prior to the study treatment at baseline, and then after injection at Weeks 1, 4 and 12, and at discretionary visits if required at Weeks 16, 20 and 24 and at end of study. The least squares mean change from baseline at Weeks 1, 4 and 12 are reported.

    The Tardieu Scale in the GSC was used to assess spasticity with the knee extended. The spasticity grade (Y) assesses quality of muscle reaction on a 5-point scale (measured at fast speed): 0 = no resistance throughout passive movement; 1 = slight resistance throughout passive movement; 2 = clear catch at precise angle, interrupting passive movement, followed by release; 3 = fatigable clonus (less than 10 seconds when maintaining pressure) occurring at a precise angle, followed by release; 4 = unfatigable clonus (more than 10 seconds when maintaining pressure) occurring at precise angle. The Tardieu Scale ratings were made prior to the study treatment at baseline, and then after injection at Weeks 1, 4 and 12, and at discretionary visits if required at Weeks 16, 20 and 24 and at end of study. The least squares mean change from baseline for spasticity grade at Weeks 1, 4 and 12 are reported.

    The Tardieu Scale in the soleus was used to assess spasticity with the knee flexed. Assessments were made at slow (V1) and fast (V3) speeds of stretch. Slow speed of muscle stretch measures the range of passive motion. During a slow stretching movement, the examiner determines the angle of movement arrest (XV1), either due to subject discomfort or a mechanical resistance.

    Range of active dorsiflexion of the ankle joint, both with the knee flexed (90°) and extended (measured by goniometry) was used to assess treatment response. The measurements were made prior to the study treatment at baseline, and then after injection at Weeks 1, 4 and 12, and at discretionary visits when needed at Weeks 16, 20 and 24 and at end of study. The least squares mean change from baseline at Weeks 1, 4 and 12 are reported.
  • Least Squares Mean Change From Baseline in Lower Limb Pain at Weeks 1, 4 and 12 [ Time Frame: Baseline and Weeks 1, 4 and 12 ]
    The intensity of lower limb pain was evaluated using the Scale of Pain Intensity (SPIN) which provided a pictorial representation of pain in a 6-point graphic scale with the degree of red shading inside a circle representing the intensity of pain. The bottom and top of the scale are anchored by two extremes: 'no pain' (circle with no red shading and scored as 0) and 'pain as bad as it could be' (circle completely red and scored as 5), marked with either verbal or visual cues. The intervening points are represented by red circles increasing proportionally in size. The subject marks the circle that best indicates their pain intensity. The SPIN assessments were obtained prior to the study treatment at baseline, and then after injection at Weeks 1, 4 and 12, and at discretionary visits when needed at Weeks 16, 20 and 24 and at end of study. The least squares mean change from baseline at Weeks 1, 4 and 12 are reported.
