Purpose. Assessment of the muscles force of knee flexors and extensors in children with a scoliosis of the first degree and knock-knees and comparison with healthy children. Basic procedures. Forty-nine boys and girls aged 10-12 years participated in this research project. The subjects were divided into three research groups. Group I included children with first degree scoliosis; Group II children with knock-knees; and Group III healthy children. An analysis of force-velocity parameters of knee flexors and extensors in isokinetic conditions (with the loads of 1.05 rad/s (60°/s), 3.14 rad/s (180°/s) and 4.19 rad/s (240°/s)) was carried out. Each subject had to perform flexion and extension movements of the knee five times, developing peak torque in the shortest time possible in each movement. Main findings. The research showed that healthy children obtained significantly higher values of peak torque, total work and mean power as compared with the other children. However, no significant differences between values obtained by scoliotic children and children with knock-knees were found. Conclusions. Corrective exercise programs for children with scoliosis and children with knock-knees should be accompanied by general fitness exercises directed at improvement of force and endurance of lower limb muscles.

Hipoterapia jest jedną z metod rehabilitacji dzieci z mózgowym porażeniem dziecięcym (mpd), bazującą na neu-rofizjologii. Aby miała prawidłowy przebieg w kierunku reedukacji nerwowo-mięśniowej, trzeba zastosować wiele elementów. Jednym z nich jest ustawienie zespołu hipoterapeutycznego. Ma ono wpływ na obraz dziecka z mpd siedzącego na koniu i powoduje zmiany w sposobie reagowania na działanie siły odśrodkowej. Dziecko siedzące na koniu prowadzonym od wewnętrznej strony okręgu lepiej przenosi masę ciała i "wydłuża" bok tułowia strony obciążonej dzięki wspomagającemu działaniu siły odśrodkowej.

Hippotherapy is one of the methods used in rehabilitation of children with infantile cerebral palsy (ICP). Since this disorder is very specific when it comes to rehabilitation of children, methods which are based on neurophysiology should be used. Various elements need to be included in order for hippotherapy to be effective in terms of neuromuscular re-education. One of these elements is positioning of the hippotherapeutic team as it influences the clinical picture of a disabled child. The child while sitting on a horse led from the inner side of the circle achieves greater improvement in shifting the body weight and elongating the loaded side of the body thanks to supportive activity of the centrifugal force.
