Overview of Studies.

I = intervention, C = control, RCT = Randomized controlled trial;AAN Classes[64]: I = rigorous RCT; II = matched prospective cohort studies or RCTs in a representative population lacking one of the criteria in class I; III = all other controlled trials; IV, all other studies*sample size at initial enrolment; final sample of 38 intervention and 34 control participants;**sample size at initial enrolment; final sample of 71 participants;***sample had majority of participants with TBI and was therefore included in this review.Overview of Studies.I即干预组（intervention）、C即对照组（control），RCT为随机对照试验（Randomized controlled trial，RCT）；美国神经病学学会（American Academy of Neurology）分类标准[64]如下：I类为严格的随机对照试验；II类为匹配性前瞻性队列研究，或在不满足I类标准的代表性人群中开展的随机对照试验；III类为其余所有对照试验；IV类为其余所有研究*：初始入组样本量，最终干预组与对照组分别剩余38名、34名受试者；**初始入组样本量，最终剩余71名受试者；***该研究样本中绝大多数受试者为创伤性脑损伤（Traumatic Brain Injury，TBI）患者，因此被纳入本综述。研究概况。
