Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Amplitude of electromyographic activity of peroneus longus, peroneus brevis, soleus, vastus medialis, gluteus medius, tibialis anterior. Timepoint: 1- Before intervention 2- Immediately after the 1st session of intervention 3- After the last session of intervention 4- Three months after the end of the last session of intervention. Method of measurement: Surface electromyography device (average amplitude of muscular activity 200 milliseconds before - 200 milliseconds after initial foot-ground contact).;Onset time of peroneus longus, peroneus brevis, soleus, vastus medialis, gluteus medius, tibialis anterior. Timepoint: 1- Before intervention 2- Immediately after the 1st session of intervention 3- After the last session of intervention 4- Three months after the end of the last session of intervention. Method of measurement: Surface electromyography device (time difference between initial foot-ground contact and onset of electromyographic activity of each muscle). | — |
Secondary
| Measure | Time frame |
|---|---|
| Functional status scores. Timepoint: 1- Before intervention, 2- After the last intervention session, 3- Three months after the last intervention session.
