摘要

背景:Sahrmann五级核心稳定性测试方案已被用于评估核心肌肉稳定脊柱的能力。然而,对Sahrmann协议的验证研究是有限的。目的:本研究的目的是比较不同水平的Sahrmann五级核心稳定性(1-5级)对腹直肌(RA)、腹外斜肌(EO)和腹横/内斜肌(TrA/IO)肌肉活动的影响。方法:招募22名无症状男性,年龄21.3 6±1.59岁。指导参与者进行最大自愿收缩(MVC)和五个级别的Sahrmann五级核心稳定性测试,指导压力生物反馈单元(PBU)。将Sahrmann五级核心稳定性试验中各肌肉的表面肌电图(EMG)数据归一化为MVC的百分比。结果:Sahrmann五水平核心稳定性试验结果显示,RA [χ 2 (4) = 64.80, p .001]、EO [χ 2 (4) = 58.11, p .001]、TrA/IO [χ 2 (4) = 56.00, p .001]的归一化肌电信号在5个水平间差异均有统计学意义。事后分析显示,Sahrmann 5级和3级的腹部肌电图信号明显高于4级、2级和1级(p 0.001)。结论:综上所述,Sahrmann五级核心稳定性测试根据Sahrmann测试水平的不同而不同。在第3级和第5级观察到明显较高的腹肌活动。因此,未来应重新考虑Sahrmann五级核心稳定性测试中第3级和第4级的分类交换。

Background: Sahrmann five-level core stability test protocol has been used to evaluate the ability of the core muscles to stabilize the spine. However, validation studies on the Sahrmann protocol are limited. Objective: The purpose of this study was to compare the different levels of Sahrmann five-level core stability (levels 1–5) on the muscle activity of rectus abdominis (RA), external oblique (EO), and transverse abdominis/internal oblique (TrA/IO). Methods: Twenty-two asymptomatic male participants aged 21.36±1.59 years were recruited. Participants were instructed to perform maximum voluntary contraction (MVC) and five levels of Sahrmann five-level core stability test guided with a pressure biofeedback unit (PBU). The surface electromyography (EMG) data of each muscle during five levels of Sahrmann five-level core stability test were normalized as a percentage of MVC. Results: Results showed significant differences in the normalized EMGs of RA [χ2(4) = 64.80, p<0.001], EO [χ2(4) = 58.11, p<0.001], and TrA/IO [χ2(4) = 56.00, p<0.001] between the five levels of Sahrmann five-level core stability test. Post-hoc analysis revealed Sahrmann levels 5 and 3 have significantly higher abdominal EMG signals than levels 4, 2, and 1 (p<0.001). Conclusion: In conclusion, the Sahrmann five-level core stability test differs according to the level of Sahrmann tests. Significantly higher abdominal muscle activities were observed during levels 3 and 5. Therefore, the classification exchange in levels 3 and 4 of the Sahrmann five-level core stability test should be reconsidered in the future.
