长期或短期呼吸训练对不同慢性非特异性腰痛患者疗效随机对照试验的meta分析

Meta analysis on randomized controlled trials of efficacy of long-term orshort-term breathing training in patients with differentchronic non-specific low back pain

目的 研究呼吸训练对慢性非特异性腰痛(CNLBP)患者的治疗效果。方法 检索Pubmed、Embase、Web of Science、Cochrane Library、中国知网、中国生物医学文献数据库、万方、维普,获取呼吸相关训练治疗CNLBP的相关试验,检索时限从建库至2022年10月。通过Cochrane系统评价手册进行质量评估,采用StataSE15.1软件进行数据分析。结果 最终获取文献19篇,研究对象共1 011例。meta分析显示,呼吸训练后,试验组视觉模拟量表(VAS)或疼痛数字量表(NRS)评分低于对照组(MD=-1.19,95%CI:-1.51~-0.87,P<0.05),Oswestry功能障碍指数问卷(ODI)评分低于对照组(MD=-0.64,95%CI:-0.91~-0.38,P<0.05)。对于不同类型的CNLBP患者,VAS评分改善效果由高到低依次为产后患者(MD=-1.89,95%CI:-2.51~-1.27,P<0.05)、运动员(MD=-1.46,95%CI:-1.79~-1.13,P<0.05)、一般人群(MD=-1.01,95%CI:-1.40~-0.61,P<0.05)。结论 呼吸训练对各类人群所患CNLBP的疼痛、功能障碍、本体感觉和姿势控制均有改善效果。

Objective To study the efficacy of breathing training in the patients with chronic non-specific low back pain(CNLBP).Methods The databases of Pubmed,Embase,Web of Science,Cochrane Library,CNKI,China Biomedical Literature Database,Wanfang Database and VIP Database were searched for obtaining relevant trials of respiratory-related training for treating CNLBP.The retrieval time limit was from the database establishment to October 2022.The quality assessment was performed by using the Cochrane Manual for Systematic Reviews,and the data analysis was performed by using StataSE15.1 software.Results Nineteen articles were finally obtained,involving in 1011 cases.The meta analysis showed that the visual analogue scale(VAS)score or pain numerical scale(NRS)score in the experiment group were lower than those in the control group(MD=-1.19,95%CI:-1.51 to-0.87,P<0.05),and the Oswestry dysfunction index(ODI)score was lower than that in the control group(MD=-0.64,95%CI:-0.91 to-0.38,P<0.05).For different types of the patients,the improvement effects of VAS score for different types of patients with CNLBP from high to low were in turn postpartum patients(MD=-1.89,95%CI:-2.51 to-1.27,P<0.05),athletes(MD=-1.46,95%CI:-1.79 to-1.13,P<0.05)and general population(MD=-1.01,95%CI:-1.40 to-0.61,P<0.05).Conclusion The breathing training has the improvement effect for pain,dysfunction,proprioception and posture control in various populations with CNLBP.
