  • Change From Baseline in Ashworth Scale (AS) Score of Primary Target Clinical Pattern [ Time Frame: Week 4 ] [ Designated as safety issue: No ]

    Primary target clinical pattern was defined by investigator for each subject at baseline visit and was either flexed wrist or clenched fist or flexed elbow.

    The Ashworth Scale is well known and commonly used in clinical trials with spasticity. It was used to categorize severity of spasticity by judging resistance to passive movement. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension).

  • Investigator's Global Impression of Change [ Time Frame: Week 4 ] [ Designated as safety issue: No ]
    This is the co-primary outcome measure. The Global Impression of Change Scale [GICS] is used to measure the investigator's impression of change due to treatment. The response option is a common 7-point Likert scale that ranges from -3 = very much worse to +3 = very much improved.
Change from baseline in Ashworth Scale (AS) of wrist flexors [ Time Frame: Baseline to week 4 ] [ Designated as safety issue: No ]
The Ashworth Scale is a well known and commonly used scale in clinical trials with spasticity. It was considered to be the best clinical tool for measuring resistance to movement. It was used to categorize the severity of spasticity by judging resistance to passive movement. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension). Subjects with a reduction of one point were defined as responder for the aim of the primary efficacy analysis.
