IncobotulinumtoxinA (Xeomin) Versus Placebo in the Treatment of Post-stroke Spasticity of the Upper Limb

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.

Starting with the visit 2 weeks after baseline injection the subject was asked if he/she experienced an treatment effect and if "yes": when. If the subject did not experience an treatment effect he/she was asked again at each of the following visits (at week 4, 8, and 12) of the Main Period until the answer was "yes" or until the final visit of the Main Period was performed.

For subjects without any treatment effect the time to onset of effect was censored at the last visit of the Main Period.

Subject who reported an onset of treatment effect were asked at each visit/telephone contact starting at week 4 at earliest if he/she felt that there was a waning of the treatment effect. The same question was asked at each of the following telephone contacts and visits (up to the Final Visit of the Main Period) if the answer at the respective previous visit was "no". If the patient answered with "yes" he/she will be asked at which week after the injection (= the time span in weeks) the waning of effect occurred. For all subjects without an onset of treatment effect the waning was set to zero.

The duration of treatment effect is defined as the time period from the day of injection until the time point of a need for a new injection agreed by the patient and the investigator. For subjects without any treatment effect the duration of effect was set to zero.
