Plantar Flexor Eccentric Training in Chronic Hemiparesis

"The first, preparatory phase, lasts two weeks, aiming at making the participant familiar with the principles of eccentric training. Participants first experience the muscle recruitment patterns (during two sessions), then are prepared to induce protective response from the plantar flexors, conditioning these muscles for higher subsequent eccentric intensities.~The aim of the second, training phase per se, which lasts six weeks, is to induce muscular and neurological adaptations through a steady increase in work intensity to stimulate muscle plasticity until the end of the program - varying volume, load and speed.~Perceived exertion is quantified using Borg's scale (expected rating between 3 and 6) to ensure sufficient work intensity and prevent excessive fatigue. Musculoskeletal pain is assessed before and after each session through a Visual Analog Scale (0-10). Verbal encouragements and advising on correct exercise execution are provided by the therapist along each session."

The participant visits a physiotherapist depending on the prescription, as in current practice
