摘要
目的:通过施加不同条件下的振动刺激,探讨振动训练对于慢性下背痛患者腰腹部肌群表面肌电信号的影响。利用表面肌电分析的方法,寻求最佳的振动频率和运动方式。
方法:采用MyoResearch XP Master Software Version 1.07.17表面分析系统测试21例慢性下背痛患者腰腹部肌肉的肌肉电信号。所有受试者分别在振动频率为0Hz、5Hz、10Hz、15Hz下完成平板支撑、侧撑、V字支撑三个动作。
结果:①竖脊肌的表面肌电值:在不同动作之间均有显著性差异(P<0.05),在平板支撑和V字支撑的情况下,不同频率之间具有显著性差异(P<0.05)。②腹外斜肌的表面肌电值:在四种频率的情况下,不同动作之间均有显著性差异(P<0.05),平板支撑和侧撑的情况下,不同频率之间具有显著性差异(P<0.05)。③腹直肌的表面肌电值:在0Hz和5Hz的情况下,不同动作之间均有显著性差异(P<0.05),在三组动作的情况下,不同频率之间均没有显著性差异(P>0.05)。
结论:不同振动条件的刺激,对慢性下背痛患者腰腹部肌群影响不同。竖脊肌最佳的振动频率为15Hz,最佳的振动动作为侧撑;腹外斜肌最佳的振动频率为15Hz,最佳的振动动作为V字支撑;腹直肌的振动动作为V字支撑,就不同频率而言,虽然腹直肌随着频率的增高,放电量逐渐增加,但是不会对肌肉产生显著性影响。 |

Abstract
Objective: To explore the influence of vibration stimulation on chronic low back pain patients lumbo-abdominal major muscles under different vibration stimulation conditions, and to determine the best vibration frequency and location by surface electromyography (sEMG) analysis.
Method: sEMG signals from the lumbo-abdominal major muscles of 21 chronic low back pain patients were measured with the MyoResearch XP Master Software Version 1.07.17. Each subjects performed 3 exercises on 0Hz, 5Hz, 10Hz, 15Hz a vibration platform: plank, side stay and the “V” crunch.
Result: ①The surface electromyography of erector muscles showed significant difference between different exercises (P<0.05). Under plank and “V” crunch, there were significant differences between different frequency (P<0.05). ②The external oblique surface EMG values: in the four case of frequency, there were significant differences between different exercises (P<0.05). Under plank and side stay conditions, there were significant differences between different frequency (P<0.05). ③The surface electromyography of rectus abdominis muscle: there were significant differences between different movements (P<0.05) under 5Hz and 0Hz. There was no significant difference in frequency between three groups (P>0.05).
Conclusion: Different vibration stimulation conditions has different effects on the lumbo-abdominal major muscles in patients with chronic lower back pain. Erector muscles: the best frequency of vibration is 15Hz. the best exercise is side stay. External oblique: the best frequency of vibration is 15Hz, the best exercise is side stay. Rectus abdominis: the best exercise on the vibration platform is “V” crunch. Although the rectus abdominis discharge capacity had increased with increasing frequency, but the muscles were not activated significantly. |
