Cerebral stroke is one of the most important issues for modern medicine. Despite the fact that numerous activities have been undertaken for the purpose of raising awareness and significance of prevention, this condition still remains one of the main reasons behind disability. The objective of the work was to assess the effects of the type of therapy, age and period from the incident occurrence, on the progress of rehabilitation of imbalance and body stability observed in a group of researched patients, on the basis of results obtained according to the Berg Balance Scale, tandem balance test, Kwolek’s loading symmetry index and Timed Up and Go test. The test group comprised of 55 post-stroke patients. The group consisted of 29 women (52.73%) and 26 men (47.27%). The average age of the subjects was 61.02 years (age range between 33-85 years). A number of the patients were subjected to rehabilitation with the use of classic kinesitherapy, whereas the remaining group underwent rehabilitation based on the proprioceptive neuromuscular facilitation method (PNF).
