Individuals with cerebral palsy (CP) are suggested to be less active than typically developing controls (TDs). However, their higher physical activity (PA) energy expenditure during a given activity should be considered. We investigated PA in 10 children and young adults with CP (seven males, 15.4 ± 5.1 years, and Gross Motor Function Classification System [GMFCS] level I/III) and eight TDs (six males, 15.3 ± 4.2 years). PA was assessed with a triaxial accelerometer at baseline and, in participants with CP, during a 3-month exercise intervention. Data were analyzed for sedentary time, light PA, and moderate-to-vigorous PA using both general and, for participants with CP, GMFCS-specific cutoffs. Statistical analyses included independent and paired sample t-tests. Based on the general cutoffs, TD and CP participants accumulated on average 516.0 ± 122 and 610 ± 92 min/day sedentary time, 155 ± 37 and 138 ± 46 min/day light PA, and 76 ± 28 and 58 ± 30 min/day moderate-to-vigorous PA at baseline. No statistically significant between-group differences were found (p ≥ 0.081). When applying GMFCS-specific cutoffs, participants with CP on average accumulated 537 ± 105, 206 ± 61, and 64 ± 31 min/day sedentary time, light PA, and moderate-to-vigorous PA. These values differed from their values based on general cutoffs (p ≤ 0.004). The 51 min difference in light PA in favor of the CP group was borderline significant (p = 0.054). In the CP group, PA did not change from baseline to follow-up (p ≥ 0.098). In conclusion, children and young adults with CP may be as active as TDs, especially when their higher PA energy cost is considered. Muscle strength and gait performance improving exercise did not seem promising in facilitating PA. TRIAL REGISTRATION: ISRCTN69044459.
与正常发育的对照组（TDs）相比，脑瘫（CP）患者的活动量被认为较少。然而，应该考虑到他们在特定活动中较高的身体活动（PA）能量消耗。我们调查了10名患有CP的儿童和年轻人（7名男性，15.4±5.1岁，粗大运动功能分类系统[GMFCS]为I/III级）和8名TDs（6名男性，15.3±4.2岁）的身体活动情况。在基线时使用三轴加速度计评估身体活动情况，对于患有CP的参与者，在为期3个月的运动干预期间也进行评估。使用通用的以及针对患有CP的参与者的GMFCS特定临界值，对久坐时间、轻度身体活动和中度至剧烈身体活动的数据进行分析。统计分析包括独立样本t检验和配对样本t检验。根据通用临界值，TD组和CP组参与者在基线时平均每天久坐时间分别为516.0±122分钟和610±92分钟，轻度身体活动时间分别为155±37分钟和138±46分钟，中度至剧烈身体活动时间分别为76±28分钟和58±30分钟。未发现组间有统计学显著差异（p≥0.081）。当应用GMFCS特定临界值时，患有CP的参与者平均每天久坐时间、轻度身体活动和中度至剧烈身体活动分别为537±105分钟、206±61分钟和64±31分钟。这些值与基于通用临界值的值不同（p≤0.004）。轻度身体活动中有利于CP组的51分钟差异接近显著（p=0.054）。在CP组中，身体活动从基线到随访没有变化（p≥0.098）。总之，患有CP的儿童和年轻人可能与TDs一样活跃，特别是当考虑到他们较高的身体活动能量消耗时。改善肌肉力量和步态表现的运动在促进身体活动方面似乎没有前景。试验注册：ISRCTN69044459。
