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.
