PT, PhDPediatric Physical Therapy: Summer 2010 - Volume 22 - Issue 2 - pp 180-187 doi: 10.1097/PEP.0b013e3181db8aaa Research Report Abstract In Brief Author Information Abstract Purpose: The purposes of this study were to describe (1) the types of exercise participation of adolescents with cerebral palsy; (2) the weekly duration of stretching, strengthening, and cardiovascular exercise; (3) how the level of activity compares with national health guidelines; and (4) the change in participation over 4 years. Methods: Participants included 126 males and 104 females (mean age = 14.7 years, SD = 1.7 years) who reported physical activities in the previous week. Analyses included frequency counts and proportions, stacked bar graphs, and 2-way analyses of variance of exercise participation by Gross Motor Function Classification System (GMFCS) and sex. Results: A significant main effect of GMFCS level was detected for light and moderate exercise. A significant interaction of GMFCS level and sex was found for stretching; females stretched more. An average of 9.4% and 11.4% of our sample participated in weekly levels of moderate and vigorous exercise, respectively. Conclusions: Pediatric physical therapists should promote increased exercise participation rates among youths with cerebral palsy. In Brief In this study the authors found that low numbers of adolescents with CP participated in &#x201C;moderate&#x201D; and &#x201C;vigorous&#x201D; exercise on a weekly basis and that their participation levels declined over a 4-year period. The authors urge pediatric physical therapists to promote increased exercise participation among youth with CP.
