To determine the effectiveness of an 8-week internet-based, lifestyle physical-activity intervention for adolescents with cerebral palsy (CP).
A randomized controlled trial using concealed allocation with blinded assessments at baseline, 10, and 20 weeks. Forty-one adolescents with CP participated (26 males, 15 females; mean age 13y 7mo, SD 1y 8mo, range 11-17y; Gross Motor Function Classification System levels: I, n=21; II, n=17; III, n=3; unilateral distribution n=16, bilateral n=25). Primary outcome was physical activity (NL-1000 accelerometers and self-report [Multimedia Activity Recall for Children and Adolescents: MARCA]). Secondary outcomes were exercise knowledge (a purpose-designed scale), attitudes, intention and self-efficacy (Lifestyle Education for Activity Program II scales), self-reported sedentary behaviour (MARCA), and functional capacity (6-min walk test).
At 10 weeks the intervention group showed no increased physical activity compared with the comparison group (weekly steps: change of +2420 vs -12189 steps p=0.06; weekly moderate-to-vigorous physical activity: change of +70 vs +8min, p=0.06; weekly distance walked: change of +3 vs -9.1km, p=0.05) and exercise knowledge (12% vs 1% improvement, p=0.08). There were no statistically significant differences for these outcomes at 20 weeks, or in self-reported physical activity at 10 or 20 weeks.
There was a positive short-term pattern for improvement in physical activity and knowledge. Internet-based programs may offer an alternative for participants unable to attend regular face-to-face physical activity programs.
确定 8 周基于互联网的生活方式体育活动干预对脑瘫（CP）青少年的有效性。
采用隐蔽分组、基线、10 周和 20 周双盲评估的随机对照试验。41 名 CP 青少年参与（26 名男性，15 名女性；平均年龄 13 岁 7 个月，标准差 1 岁 8 个月，范围 11-17 岁；粗大运动功能分级系统水平：I 级 21 名；II 级 17 名；III 级 3 名；单侧分布 16 名，双侧 25 名）。主要结局是体力活动（NL-1000 加速度计和自我报告[多媒体活动回忆儿童和青少年：MARCA]）。次要结局是运动知识（专门设计的量表）、态度、意向和自我效能感（生活方式教育活动计划 II 量表）、自我报告的久坐行为（MARCA）和功能能力（6 分钟步行测试）。
在 10 周时，与对照组相比，干预组的体力活动没有增加（每周步数：增加+2420 对-12189 步，p=0.06；每周中度至剧烈体力活动：增加+70 对+8 分钟，p=0.06；每周步行距离：增加+3 对-9.1 公里，p=0.05）和运动知识（12%对 1%的改善，p=0.08）。在 20 周时，或在 10 周或 20 周时的自我报告体力活动中，这些结果均无统计学意义。
在短期内，体力活动和知识均有积极改善。基于互联网的计划可能为无法参加常规面对面体育活动计划的参与者提供一种替代方案。
