The purpose of this systematic review was to: (I) determine the quality of evidence from studies assessing trunk isokinetic strength in subjects with acute low back pain (ALBP) compared to healthy subjects and (II) establish reference values of isokinetic trunk strength in subjects with ALBP.
Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) statements were followed using keywords associated with trunk, strength and low back pain. Four databases were used: PubMed, Web of Science, Scopus and SPORTDiscus. Methodological quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS).
A total of 1604 articles were retrieved, four included in this review. All were evaluated as high risk of bias (Rob). Due to the high Rob and the diversity of protocols, instruments and variables used, it was not possible to determine reference values for subjects with ALBP, we can only establish a range of flexion peak torque (PT) between 175.1 and 89.7 Nm at 60°/s and between 185 and 81.5 Nm at 120°/s, and for extension PT between 240.0 and 91.5 Nm at 60°/s and between 217.5 and 69.2 Nm at 120°/s in subjects with ALBP.
Due to the low quality of the evidence and the diversity of protocols used when measuring trunk isokinetic strength, it is necessary to carry out new high-quality research to establish reference values of trunk strength in subjects with ALBP.
本系统评价的目的是：（I）确定与健康受试者相比，评估急性下腰痛（ALBP）患者躯干等速肌力的研究证据质量；（II）确定ALBP患者等速躯干肌力的参考值。
遵循系统评价和荟萃分析的首选报告项目（PRISMA）声明，使用与躯干、力量和下腰痛相关的关键词。使用了四个数据库：PubMed、科学网、Scopus和SPORTDiscus。使用诊断准确性研究质量评估（QUADAS）评估方法学质量。
共检索到1604篇文章，本评价纳入4篇。所有研究均被评估为高偏倚风险（Rob）。由于高Rob以及所使用的方案、仪器和变量的多样性，无法确定ALBP患者的参考值，我们只能确定ALBP患者在60°/s时屈曲峰值扭矩（PT）的范围为175.1至89.7 Nm，在120°/s时为185至81.5 Nm；伸展PT在60°/s时为240.0至91.5 Nm，在120°/s时为217.5至69.2 Nm。
由于测量躯干等速肌力时证据质量低且使用的方案多样，有必要开展新的高质量研究以确定ALBP患者躯干力量的参考值。
