What is the effect of a sitting training protocol in people early after stroke on sitting ability and quality, and does it carry over to mobility?
Randomised placebo-controlled trial with concealed allocation, assessor blinding and intention-to-treat analysis.
Twelve individuals who had a stroke less than three months previously and were able to sit unsupported.
The experimental group completed a 2-week sitting training protocol that involved practising reaching tasks beyond arm's length. The control group completed a 2-week sham sitting training protocol that involved practising cognitive-manipulative tasks within arm's length.
The primary outcome was sitting ability (maximum reach distance). Secondary outcomes were sitting quality (reach movement time and peak vertical force through affected foot during reaching) and carry over to mobility (peak vertical force through affected foot during standing up and walking speed during 10 m Walk Test). Outcome measures were taken before and after training and six months later.
After 2 weeks' training, the experimental group had increased their maximum reach distance by 0.17 m (95% CI 0.12 to 0.21), decreased their movement time by 0.5 s (95% CI -0.8 to -0.2), increased their peak vertical force through the affected foot during reaching by 13% of body weight (95% CI 6 to 20) and increased their peak vertical force through the affected foot during standing up by 21% of body weight (95% CI 14 to 28) compared with the control group. After 6 months, significant between-group differences were maintained for maximum reach distance and peak vertical force through the affected foot during standing up.
The sitting training protocol was both feasible and effective in improving sitting and standing up early after stroke and somewhat effective six months later.
中风后早期进行坐位训练方案对患者的坐位能力和质量有何影响,这种影响能否延续到移动能力方面?
采用随机安慰剂对照试验,实施隐蔽分组、评估者盲法和意向性分析。
12名在不到三个月前中风且能够独立坐立的个体。
实验组完成一项为期2周的坐位训练方案,其中包括练习超出手臂长度的够物任务。对照组完成一项为期2周的模拟坐位训练方案,其中包括练习在手臂长度范围内的认知操作任务。
主要指标为坐位能力(最大够物距离)。次要指标为坐位质量(够物时的够物动作时间和患侧足部的垂直力峰值)以及对移动能力的影响(站立时患侧足部的垂直力峰值和10米步行测试中的步行速度)。在训练前后及六个月后进行观察指标的测量。
经过2周训练后,与对照组相比,实验组的最大够物距离增加了0.17米(95%可信区间为0.12至0.21),够物动作时间减少了0.5秒(95%可信区间为-0.8至-0.2),够物时患侧足部的垂直力峰值增加了体重的13%(95%可信区间为6至20),站立时患侧足部的垂直力峰值增加了体重的21%(95%可信区间为14至28)。六个月后,在最大够物距离和站立时患侧足部的垂直力峰值方面,两组之间仍存在显著差异。
坐位训练方案在中风后早期改善坐位和站立能力方面既可行又有效,六个月后也有一定效果。
