In this work is considered effective influences of physical exercises in water. The dynamics of development of functional indexes is shown by the kardio-respirator and kinesthesia systems.

It is well-proven that the most substantial changes happened at the estimation of indexes of dynamic force of muscles and goniometry of lower limbs. Leaning against the got results, it is possible to recommend a hydrokinezotherapy in treatment of patients with this pathology.
