Background:The present study aimed to evaluate the impact of the number of occupational therapy sessions as neurodevelopmental technique (NDT) on gross motor function and other moving outcomes in children with cerebral palsy (CP).
Methods:The present study evaluated all the patients who referred to the occupational therapy service centers of the private sector and welfare organization in Shiraz, Iran in 2013. The studied patients included the children of both genders affected by spastic CP. A total of 59 individuals met the inclusion criteria and entered the study. A researcher-made questionnaire including 66 questions of gross motor function measure (GMFM) was used. This questionnaire measure the gross motor function in 5 dimensions including lying and rolling, sitting, crawling and kneeling, standing and walking, running and jumping. Negative binomial regression model with logarithmic function was applied in STATA 11 software.
Results: 59.3% of the patients were boy. According to our results, 38.3%, 33.3% and 38.3% were affected by spastic diplegia, spastic hemiplegia and spastic quadriplegia respectively. Children at level one of gross motor function had 1.3 times higher achievements, compared to the individuals at other levels (P=0.003) and the subjects who participated in more than five sessions per week had 1.04 more achievements than others (P=0.001).
Conclusion:The results of this study showed that the higher number of common occupational therapy sessions lead to more success in the gross motor function of the children affected by level 1 CP of gross motor function classification. Further investigations are required in terms of other motor levels.
