The aim of this study was to analyze the strength status of the rectus abdominis muscle in patients with incisional hernia and the relationship between the width of the hernia defect and the strength of the rectus abdominis muscle.
This is a observational cohort study of patients with medial line incisional hernia (July-October 2022), classified as W2 according to the European Hernia Society (EHS). The data collected were demographic and clinical characteristics related to hernia, and measure of the rectus abdominis muscle strength using an isokinetic dynamometer and a strain gauge. We analyzed the relationship between hernia width and rectus abdominis muscle strength with correlation tests to adjustment by age, sex, BMI, and body composition.
A total of 40 patients (64% female) with a mean age of 57.62 years (SD 11) were enrolled in the study. The mean BMI was 29.18 (SD 5.06), with a mean percentage of fat mass of 37.8% (SD 8.47) and a mean percentage of muscle mass of 60.33% (SD 6.43). The maximum width of the hernia defect was 6.59 cm (SD 1.54). In the male group, the mean bending force moment (ISOK_PT) was 94.01 Nw m (SD 34.58), bending force moment relative to body weight (ISOK_PT_Weight) was 103.32 Nw m (SD 37.48), and peak force (PK_90) was 184.71 N (SD 47.01). In the female group, these values were 58.11 Nw m (SD 29.41), 66.48 Nw m (SD 32.44), and 152.50 N (SD 48.49), respectively. Statistically significant differences were observed in the relationship between the data obtained with the isokinetic dynamometer and sex (p = 0.002), as well as between the data obtained with the isokinetic dynamometer and age (p = 0.006). Patients in the 90th percentile (P90) of rectus abdominis muscle strength also had smaller hernia defect widths (p = 0.048).
In this study, age and sex were identified as the most statistically significant predictor variables for rectus abdominis muscle strength. The width of the hernia defect exhibited a trend towards statistical significance.
本研究旨在分析切口疝患者腹直肌的力量状态，以及疝缺损宽度与腹直肌力量之间的关系。
这是一项观察性队列研究，纳入了 2022 年 7 月至 10 月患有中线切口疝的患者（EHS 分类为 W2）。收集的数据包括与疝相关的人口统计学和临床特征，以及使用等速测力计和应变计测量腹直肌力量。我们分析了疝宽度与腹直肌力量之间的关系，并通过年龄、性别、BMI 和身体成分进行了相关性测试。
共纳入 40 名患者（64%为女性），平均年龄为 57.62 岁（标准差 11）。平均 BMI 为 29.18（标准差 5.06），脂肪质量百分比为 37.8%（标准差 8.47），肌肉质量百分比为 60.33%（标准差 6.43）。疝缺损的最大宽度为 6.59 厘米（标准差 1.54）。在男性组中，弯曲力力矩（ISOK_PT）的平均值为 94.01 Nw m（标准差 34.58），弯曲力力矩与体重的比值（ISOK_PT_Weight）为 103.32 Nw m（标准差 37.48），峰值力（PK_90）为 184.71 N（标准差 47.01）。在女性组中，这些值分别为 58.11 Nw m（标准差 29.41）、66.48 Nw m（标准差 32.44）和 152.50 N（标准差 48.49）。使用等速测力计获得的数据与性别（p=0.002）以及与年龄（p=0.006）之间存在统计学显著差异。腹直肌力量处于第 90 百分位数（P90）的患者疝缺损宽度也较小（p=0.048）。
在这项研究中，年龄和性别被确定为腹直肌力量的最具统计学意义的预测变量。疝缺损的宽度显示出统计学意义的趋势。
