This study aimed to quantitatively analyze the effects of neuromuscular training (NMT) on dynamic balance in healthy athletes through a systematic review and meta-analysis of randomized controlled trials.
Searches on six databases for randomized controlled trials examining the impact of NMT on athletes' balance ability. The search period extended from the inception of the database to March 16, 2024, languages are limited to Chinese and English. Review Manager 5.1 was used for literature quality assessment and data analysis. Stata 15.0 software was used for assessing publication bias, employing the clipping method, and conducting sensitivity analysis. The Grading of recommendations assessment development and evaluation (GRADE) was used to assess the certainty of evidence. Effect size (ES) was used to evaluate the impact effect of the results.
(1) Meta-analysis: A total of 7 papers met the inclusion criteria, and the meta-analysis indicated that NMT had a positive impact on the dynamic balance ability of the right (SMD = 0.74) and left (SMD = 0.70) lower limb of athletes, and a statistically significant difference was observed ( < 0.01). Subgroup analysis revealed that NMT did not have a positive effect ( > 0.05) on the right anterior (SMD = 0.35); However, it had a positive effect ( < 0.05) on the right posteromedial (SMD = 1.22), right posterolateral (SMD = 0.82), right composite score (SMD = 0.79), left anterior (SMD = 0.38), left posteromedial (SMD = 1.19), left posterolateral (SMD = 0.57) and left composite score (SMD = 0.86). (2) Reporting bias: Funnel plot indicated evidence of publication bias, but there was no significant asymmetry in the funnel plot after trimming and filling. The results were not reversed, indicating the robustness of the combined results. (3) Sensitivity analysis: The results of the sensitivity analysis suggest that the data in this meta-analysis are relatively stable and credible. (4) Grading the evidence: Based on GRADE scale the certainty of evidence from the included studies was determined to be moderate.
Neuromuscular training can enhance the dynamic balance ability of athletes on both the left and right sides. Therefore, neuromuscular training is an effective method for enhancing the unilateral dynamic balance ability of athletes.
本研究旨在通过对随机对照试验的系统评价和荟萃分析，定量分析神经肌肉训练（NMT）对健康运动员动态平衡的影响。
在六个数据库中检索关于NMT对运动员平衡能力影响的随机对照试验。检索期从数据库建立至2024年3月16日，语言限于中文和英文。使用Review Manager 5.1进行文献质量评估和数据分析。使用Stata 15.0软件采用剪补法评估发表偏倚并进行敏感性分析。使用推荐分级评估、制定和评价（GRADE）来评估证据的确定性。效应量（ES）用于评估结果的影响效果。
（1）荟萃分析：共有7篇论文符合纳入标准，荟萃分析表明NMT对运动员右下肢（标准化均数差[SMD]=0.74）和左下肢（SMD=0.70）的动态平衡能力有积极影响，且差异有统计学意义（P<0.01）。亚组分析显示，NMT对右前侧（SMD=0.35）无积极影响（P>0.05）；然而，它对右后内侧（SMD=1.22）、右后外侧（SMD=0.82）、右综合评分（SMD=0.79）、左前侧（SMD=0.38）、左后内侧（SMD=1.19）、左后外侧（SMD=0.57）和左综合评分（SMD=0.86）有积极影响（P<0.05）。（2）报告偏倚：漏斗图表明存在发表偏倚的证据，但在剪补后漏斗图无明显不对称。结果未反转，表明合并结果的稳健性。（3）敏感性分析：敏感性分析结果表明本荟萃分析中的数据相对稳定且可信。（4）证据分级：根据GRADE量表，纳入研究的证据确定性被确定为中等。
神经肌肉训练可增强运动员左右两侧的动态平衡能力。因此，神经肌肉训练是增强运动员单侧动态平衡能力的有效方法。
