Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The surface electromyography Noraxon MyoSystem 1400A (Noraxon, USA) will be used to obtain reliable analysis of the muscle bioelectrical activity, expressed as the resting muscle tone of affected muscles. Mean rest muscle tension, expressed in microvolts [μV], will be recorded, determined as the arithmetic mean value of muscle tension in the examined group of muscles for the entire period of measurement per time unit [s]. The infrared camera MobIR M8 (Test-Therm, Poland) will be used to register thermal phenomena at the vascular level in examined muscles, as well as to visualize changes in local temperature distribution of stimulated tissues. The mean value of the tissue heat level within examined muscles will be determined, taken as the arithmetic mean of each isotherm within the whole area of measurement, expressed in Celsius degrees [°C]. The maximal and minimal temperature of the examined area also will be established, taken as a set of points with the highest level of heat within the area of measurement, expressed in Celsius degrees [°C]. | — |

|---|---|
| The Modified Ashworth Scale will be use to assess clinical changes in muslces spaticity level, before and after ESW stimulation or placebo intervention. | — |
