Research background and hypothesis. Cryotherapy could reduce spasticity for children with cerebral palsy.Research aim. The aim of this study was to determine the effect of cryotherapy on the lower limb spasticity for children with cerebral palsy.Research methods. Fourteen children with cerebral palsy spastic Diplegia aged 6–12 years were examined. The procedures of cryotherapy and physical therapy were applied to children in the test group (n = 7), and only physical therapy – for the members in the control group (n = 7). For all the subjects, the following procedures were performed before and after the research: foot extension measurements, the determination of the spasticity of flexors and selective foot motion, the estimation of balance and gross motor functions. Research  results.  After  physical  exercises  foot  extension  showed  improvement,  spasticity  of  foot  flexors reduced, foot selective movements, balance and gross motor functions improved. There was no statistical difference between the results in both groups.Discussion and conclusions. The influence of cryotherapy on the lower limb spasticity for children with cerebral palsy was not statistically significant.
