JAMA:脑震荡后要休息?NO!早期运动才可降低PPCS的发生风险!

2016-12-21 sunshine MedSci原创

虽然脑震荡治疗指南主张损伤后应休息直到症状缓解,但是目前并没有明确的证据表明损伤后避免体力活动可促进恢复。本研究旨在探讨脑震荡后7天内进行体力活动与持续脑震荡症候群发生率(PPCS)之间的关联。采用前瞻性、多中心队列研究设计(2013年8月至2015年6月)纳入3063名急性脑震荡儿童和青少年,年龄为5.00-17.99岁。分别在就诊于急救部门时、伤后第7天和第28天时使用标准化问卷评估患者的体力

虽然脑震荡治疗指南主张损伤后应休息直到症状缓解,但是目前并没有明确的证据表明损伤后避免体力活动可促进恢复。本研究旨在探讨脑震荡后7天内进行体力活动与持续脑震荡症候群发生率(PPCS)之间的关联。

采用前瞻性、多中心队列研究设计(2013年8月至2015年6月)纳入3063名急性脑震荡儿童和青少年,年龄为5.00-17.99岁。

分别在就诊于急救部门时、伤后第7天和第28天时使用标准化问卷评估患者的体力活动和持续脑震荡症候群的严重程度。通过校正分析、1:1倾向得分匹配和逆处理概率加权法(IPTW)评估早期体力活动和PPCS之间的关系。脑震荡后第7天对患者进行敏感性分析(≥3个症状)。

结果,2413名参与者(平均[SD]年龄,11.77 [ 3.35 ]年[ 39.3% ];1205名[39.3%]女性)完成了研究,其中733名(30.4%)患者伤后第28天出现了PPCS;1677名(69.5%)参加了早期的体力活动,包括轻度有氧运动(N = 795 [ 32.9% ]),体育专项运动(N = 214 [ 8.9% ]),接着是非接触式训练演习(N = 143 [ 5.9% ]),自由搏击训练(N = 106 [ 4.4% ]),或自由竞赛类运动(N = 419 [ 17.4% ]),而736名患者(30.5%)没有参与体力活动。

未经校正分析中,与未参加体力活动的患者相比,早期参与体力活动的患者其PPCS的风险较低(24.6% vs 43.5%;绝对风险差异[ARD],18.9% [ 95%,CI,14.7% - 23% ])。倾向得分匹配分析中,早期体力活动与PPCS发生的风险相关(N = 1108  [ 28.7%早期体力活动VS. 40.1%未参加体力活动];ARD,11.4% [ 95% CI,5.8% - 16.9% ]),逆处理概率加权法分析中(n = 2099  ;相对风险[RR ] 0.74 [ 95% CI,0.65-0.84 ];ARD,9.7% [ 95% CI,5.7%-13.7% ])。

与那些没有参与体力活动的患者(n = 584  ;PPCS,52.9%)相比,伤后7天有症状的患者(N = 803)中,以下患者的PPCS的发生率较低——轻度有氧活动参与者(N = 494 [ 46.4% ];ARD6.5% [ 95% CI,5.7%-12.5% ]),中度体力活动(N = 176 [ 38.6% ];ARD14.3% [ 95% CI,5.9%-22.2% ]),自由搏击训练(N = 133 [ 36.1% ];ARD16.8% [ 95% CI,7.5%-25.5% ])。亚组倾向匹配分析中并未发现存在明显的组间差异(n = 776  [ 47.2% VS. 51.5% ];ARD4.4% [ 95% CI,2.6%-−11.3% ])。

总而言之,本研究发现,5-18岁的急性脑震荡的受试者中,急性损伤后7天内参与体力活动在伤后第28天发生PPCS的风险较未参与体力活动者低。仍需设计良好的随机临床试验来确定脑震荡后早期体力活动的好处。
