To identify typical patterns of abdominal wall muscle activation in patients with diastasis recti and inguinal hernias compared to controls during the Valsalva maneuver, voluntary coughing, and physical activity.
The study included 15 subjects: 5 with diastasis recti, 4 with inguinal hernias, and 6 healthy controls. The functions of rectus abdominis (RA) and external oblique (OE) muscles were measured by surface electromyography (sEMG). Using ultrasound, the thicknesses of the RA, OE, internal oblique (IO), and transversus abdominis (TA) muscles were assessed as well as the echo intensity (EI) of RA and OE.
We found a significant effect of the type of abdominal wall pathology on the maximum sEMG amplitude ( = 0.005). There was a reliable trend in maximum sEMG amplitude, with the highest one in diastasis recti and a significantly lower one in inguinal hernias. Duncan's test showed a significant difference in muscle thickness, both on the right and left sides, between patients with diastasis and controls, but only on the left side between patients with diastasis and those with inguinal hernia ( < 0.05).
The abdominal wall pathology results in a change in the function and structure of the abdominal muscles, which can be detected using electromyography and ultrasound examination. The presence of diastasis recti is accompanied by an increase in bioelectrical activity and a decrease in thickness.
比较腹直肌分离和腹股沟疝患者与对照组在瓦尔萨尔瓦动作、自主咳嗽及身体活动期间腹壁肌肉激活的典型模式。
该研究纳入了15名受试者:5名腹直肌分离患者、4名腹股沟疝患者和6名健康对照者。通过表面肌电图(sEMG)测量腹直肌(RA)和腹外斜肌(OE)的功能。使用超声评估RA、OE、腹内斜肌(IO)和腹横肌(TA)的厚度以及RA和OE的回声强度(EI)。
我们发现腹壁病理类型对最大sEMG幅度有显著影响(P = 0.005)。最大sEMG幅度存在可靠趋势,腹直肌分离患者的幅度最高,腹股沟疝患者的幅度显著较低。邓肯检验显示,腹直肌分离患者与对照组之间,左右两侧肌肉厚度均存在显著差异,但腹直肌分离患者与腹股沟疝患者之间仅左侧存在差异(P < 0.05)。
腹壁病理改变会导致腹部肌肉功能和结构的变化,可通过肌电图和超声检查检测到。腹直肌分离的存在伴随着生物电活动增加和厚度减小。
