- Primary Outcome Measures
Name Time Method Changes from baseline in the degree of spasticity in gastrocnemius according to modified Ashworth scale (AS) From baseline to day 30 The AS is a well known and commonly used scale in clinical trials with spasticity. In spastic muscles the resistance to passive movement is assessed. It is a 5-point scale that ranges from 0 (=no increase in tone) to 4 (=limb rigid in flexion or extension).
- Secondary Outcome Measures
Name Time Method Changes from baseline in the ratio of M-response recorded from the lateral and medial gastrocnemius heads and from tibialis anterior From baseline up to day 90 Changes from baseline in angles and angle ratio of ankle joints at passive and voluntary extension From baseline up to day 90 Changes from baseline in the degree of spasticity in gastrocnemius according to modified Ashworth scale Baseline up to day 90 Percentage of decrease in M-response magnitude and area recorded from the lateral and medial gastrocnemius heads, from baseline values From baseline up to day 90 Electromyography: The amplitude of a compound muscle action potential (M-wave) is recorded. An electrical stimulation is considered supramaximal when the M-wave amplitude no longer increases while increasing the stimulus. The measurements include the M-wave amplitude and the negative peak area of the M-wave.
Changes from baseline in motor activity according to Gross Motor Function Classification Systems (GMFCS) criteria From baseline up to day 90 GMFCS is a 5-level classification system that is a standardized observational instrument for children with CP developed to measure change in gross motor function over time.
Changes from baseline in patient percentage in groups by the degree of gastrocnemius spasticity according to modified Ashworth scale From baseline up to day 90
