Summary

Neurological disorders \[such as Cerebral Vascular Accident (CVA) or Spinal Cord Injury (SCI)\] are among the most costly health problems to society in industrialized countries. For those affected, they generate severe restrictions in mobility, significantly altering their quality of life.

Deterioration in motor function after stroke or BM is closely linked to the level of force produced at joint level. This is influenced by adaptations (neurological and tissue) inherent to the pathophysiology of the injury, and characterized by the presence of a spastic paresis syndrome.

A great deal of effort is devoted to motor neurorehabilitation (particularly physiotherapy) in the days and weeks following neurological injury. This so-called sub-acute rehabilitation phase is designed to have a positive impact on the patient's motor recovery (to prevent the development of spastic paresis), and to prevent future severe limitations in the long term.

Disorders observed in the chronic phase (partial recovery of strength, severe orthopedic deformities) demonstrate the limits of current therapies. In view of the results obtained in healthy subjects, eccentric training now seems to be one of the most promising physiotherapy methods for recovering muscle strength and countering neurological disorders.

However, its use in the sub-acute rehabilitation phase has never been evaluated in post-stroke or post-BM patients, either in terms of its effects on the strength developed in the strengthened muscles, or more locally on the neurological and tissue disorders found in these patients in the context of spastic paresis.

The aim of this project is to evaluate the effects of an eccentric muscle-strengthening exercise protocol on neurological patients in the sub-acute phase of their neurological impairment. The protocol will be applied to the ankle joint, given its importance for walking and the significant deficits found at this level in neurological populations.We hypothesize that the strengthening protocol will improve muscle strength at the ankle, and generate beneficial adaptations to combat the spastic paresis syndrome (improved muscle activation, increased muscle length, muscle volume, etc.).
