Abstract

BACKGROUND

The use of unstable surfaces has been proposed to increase the neuromuscular demand. This strategy has been adopted to generate an increase in the activity of periscapular muscles due to its role in the stabilization of the scapula. However, the influence of this instability on the EMG activity remains uncertain. The aim of this study was to analyze the effects of using unstable surfaces on the EMG activity of the periscapular muscles.

METHODS

A comprehensive search in the PubMed, EMBASE, SCIELO, Web of Science, SCOPUS, Cochrane and LILACS databases was undertaken from their year of inception up to December 2019. Studies which directly investigated the EMG activity of periscapular muscles in healthy individuals while performing exercises for the upper limbs in stable and unstable conditions.

RESULTS

A total of 33 studies which evaluated a total of 678 healthy individuals were found according to the eligibility criteria. A meta-analysis identified that the EMG activity of the upper trapezius showed a trivial increase with the insertion of the unstable surface (P = 0.04; SMD = 0.14 [95%CI 0.00, 0.27]). No significant effects were observed on the middle trapezius (P = 0.10) and lower trapezius (P = 0.25). A decrease of the anterior serratus EMG activity with a small effect size was observed by implementing an unstable surface (P = 0.01; SMD = -0.21 [95%CI -0.36, -0.05]).

CONCLUSION

The use of unstable surfaces generated a trivial increase in the upper trapezius activity, and a slight decrease in the anterior serratus activity. No effect was observed on the middle and lower trapezius.

摘要

背景

使用不稳定的表面已被提议用来增加神经肌肉的需求。由于肩胛骨稳定的作用，这种策略已被用于产生肩胛带肌活动的增加。然而，这种不稳定性对肌电图活动的影响尚不确定。本研究旨在分析使用不稳定表面对肩胛带肌肌电图活动的影响。

方法

从其成立之年起，在 PubMed、EMBASE、SCIELO、Web of Science、SCOPUS、Cochrane 和 LILACS 数据库中进行了全面检索，直到 2019 年 12 月。这些研究直接调查了健康个体在稳定和不稳定条件下进行上肢运动时肩胛带肌肌电图活动。

结果

根据纳入标准，共发现 33 项研究，共评估了 678 名健康个体。荟萃分析发现，使用不稳定表面时，上斜方肌的肌电图活动略有增加（P=0.04；SMD=0.14[95%CI 0.00，0.27]）。中斜方肌（P=0.10）和下斜方肌（P=0.25）未见明显影响。使用不稳定表面时，前锯肌肌电图活动减少，效应量较小（P=0.01；SMD=-0.21[95%CI -0.36，-0.05]）。
