Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluate the muscle architecture through means of ultrasound, noting a variation of at least 5% in pre and post-intervention intra and inter-group measurements, expecting to find greater muscle fiber length and less muscle cross-sectional area in the experimental group compared to placebo | — |
Secondary
| Measure | Time frame |
|---|---|
| Evaluate the torque production capacity through isokinetic dynamometry, noting a variation of at least 5% in pre and post-intervention intra and inter-group measurements, expecting to find less force production in the experimental group compared to the placebo;Evaluate functional performance through the eight-meter walk, Timed Up and Go and Sit and Stand tests, noting a variation of at least 5% in pre and post-intervention intra and inter-group measurements, expecting to find better functional performance in the experimental group compared to placebo;Evaluate the myoelectric properties through electromyography of the medial gastrocnemius, soleus and tibialis anterior muscles, noting a variation of at least 5% in pre and post-intervention intra and inter-group measurements, expecting to find less muscle electrical activity in the experimental group compared to the placebo;Evaluate the spasticity level using the Modified Ashworth Scale, noting a variation of at least 5% in pre and post-intervention intra and inter-group measurements, expecting to find lower spasticity level in the experimental group compared to placebo | — |
