Isometric strength testing is known as a valid and reliable tool in the context of functional diagnostics and quality control for chronic low back pain rehabilitation, but reference values differ markedly between varied assessment devices, depending on their biomechanical lever arm framework. This study aimed to evaluate sex and age-specific isometric peak force reference values of trunk muscle functions in all dimensions using the Myoline® test device (Diers, Schlangenbad, Germany).
In a retrospective cross-sectional study, data of 678 (541 females, 137 males) age-clustered (18-35, 36-50, 51-65 years) low back pain patients (ICD-10: M54) were analyzed referring to their absolute (N) and body weight related (N/kg) isometric maximum peak forces in all spatial dimensions (flexion, extension, rotation, lateral flexion) and the corresponding ratios (M ± SD, 95% CI), accompanied by sex and age-related effect analyses (two-way ANOVA).
Male and younger patients were significantly stronger than females and older patients (p < 0.05), but none of the ratios differed significantly between any sex or age cluster (p > 0.05). The flexion/extension ratio showed a 1:2 relation, and the rotation and lateral flexion ratios demonstrated a 1:1 relation, but all ratios varied markedly (30-50%).
The demonstrated data represented a special norm for sex and age clustered low back pain patients assessed with the recent Myoline® test device. The markedly varying peak forces and their ratios underlined the individual diversity and heterogeneous state of functional capacities within low back pain patients.
在慢性下腰痛康复的功能诊断和质量控制方面，等长力量测试是一种有效且可靠的工具，但不同评估设备的参考值因生物力学杠杆臂框架不同而有显著差异。本研究旨在使用Myoline®测试设备（德国施兰根巴德的迪尔斯公司）评估躯干肌肉功能在各个维度上的性别和年龄特异性等长峰值力参考值。
在一项回顾性横断面研究中，分析了678例（541例女性，137例男性）年龄分组（18 - 35岁、36 - 50岁、51 - 65岁）的下腰痛患者（国际疾病分类第十版：M54）的数据，这些数据涉及他们在所有空间维度（前屈、后伸、旋转、侧屈）上的绝对（牛顿）和与体重相关（牛顿/千克）的等长最大峰值力以及相应比例（平均值±标准差，95%置信区间），同时进行了性别和年龄相关的效应分析（双向方差分析）。
男性和年轻患者明显比女性和老年患者更强壮（p < 0.05），但任何性别或年龄组之间的比例均无显著差异（p > 0.05）。前屈/后伸比例显示为1:2的关系，旋转和侧屈比例显示为1:1的关系，但所有比例差异均显著（30 - 50%）。
所展示的数据代表了使用最新Myoline®测试设备评估的年龄分组和性别分层的下腰痛患者的特殊规范。明显不同的峰值力及其比例突显了下腰痛患者功能能力的个体差异和异质性状态。
