Postural sway in children and young adults, survivors of CNS tumours.
OBJECTIVE
Brain tumours are the most common solid tumours in children and adolescents. The increasing survival rate of these patients makes their follow-up and quality of life assessment an important task. The evaluation of the negative influence of anti-cancer treatment on their balance is the aim of this study.


METHODS
The balance assessment was performed on patients who completed the treatment of CNS tumours and were disease-free at the time of the study. Eighty-eight patients aged 5 to 24 years participated in the study. Postural sway was recorded using Kistler force plate. Balance test parameters from two conditions: eyes open and eyes closed were calculated and compared with reference data. The severity of the balance disorders was scored for both conditions.


RESULTS
The balance disorders were generally not dependent on the localisation of the tumour. Only patients treated for posterior fossa tumours had a higher score (indicating pronounced balance deficit) in eyes closed condition comparing to others. The patients treated for spinal cord tumours seemed to have increased total sway path in comparison to others. The severity of the balance deficits tended to diminish in time.


CONCLUSIONS
These results suggest that the repair mechanisms of the CNS could overcome the problems inflicted by the illness and therapy.
