Abstract

Aim

The associated etiological factors of Meralgia Paresthetica (MP) are various. We hypothesized that posture misalignment and changes in muscle surrounding the Lateral Femoral Cutaneus Nerve (LFCN) can cause compression on the nerve or that patients with MP may have posture disorder due to pain, which can lead to entrapment. The purpose of study was to determine the potentional relationship between posture misalignment, muscles thickness and MP.

Methods

A cross sectional study was undertaken. Twenty-six patients patients diagnosed with MP [12 women and 14 men; median age, 48.5 (35.3–65.0) years] participated in the study. The LFCN was evaluated with ultrasound in patients with MP. The thickness of the vastus medialis, lateralis, iliopsoas, sartorius, tensor fascia lata and rectus femoris muscles was measured using ultrasound. LANSS, Visual Analogue Scale (VAS) and the Lower Extremity Functional Scale (LEFS) were assessed. Postural alignment were evaluated using DIERS formetric 4D and New York Posture Rating (NYPR) scale.

Results

Tensor facia lata muscle thickness was significantly lower in the symptomatic side (p = 0.034). There was an inversely correlation between LANSS and sartorius and iliopsoas muscle thickness (respectively, p = 0.036, p = 0.047), while the rectus femoris muscle thickness was inversely correlated with LANSS in the asymptomatic side (p = 0.038). There was a significantly relationship between LANSS and postural misalignment variables (coronal imbalance, trunk length, inflection point). Multiple linear regression analysis revealed that coronal imbalance and trunk length in postural variables were statistically significant predictors of LANSS (r ² =0.342).

Conclusion

Our findings suggest that changes in muscles surrounding LFCN and posture misalignment may contribute as an etiological factor in patients with MP or vice versa.

体位错位及股外侧皮神经周围肌肉对感觉异常痛的影响

目的感觉异常痛（Meralgia parthetica， MP）的病因多样。我们假设，姿势错位和股外侧皮神经周围肌肉的变化可能导致神经受压，或者MP患者可能由于疼痛而出现姿势障碍，从而导致夹持。本研究旨在探讨体位失调、肌肉厚度与MP之间的潜在关系。方法采用横断面研究。诊断为MP的患者26例[女性12例，男性14例；参与研究的中位年龄为48.5（35.3-65.0）岁。超声评价MP患者的LFCN。超声测量股内侧肌、股外侧肌、髂腰肌、缝匠肌、阔筋膜张肌和股直肌的厚度。评定LANSS、视觉模拟量表（VAS）和下肢功能量表（LEFS）。采用DIERS formmetric 4D和New York Posture Rating （NYPR）量表评估体位对齐。结果症状侧阔张力肌厚度明显降低（p = 0.034）。LANSS与缝匠肌、髂腰肌厚度呈负相关（p = 0.036,p = 0.047），无症状侧股直肌厚度与LANSS呈负相关（p = 0.038）。LANSS与体位失调变量（冠状不平衡、躯干长度、拐点）有显著相关。多元线性回归分析显示，体位变量中冠状失衡和躯干长度是LANSS的预测因子（r 2 =0.342）。结论：我们的研究结果表明，LFCN周围肌肉的改变和姿势错位可能是MP患者的病因之一，反之亦然。数据可用性通讯作者将根据合理要求提供当前工作中使用和分析的数据集。

期刊介绍： Gait & Posture is a vehicle for the publication of up-to-date basic and clinical research on all aspects of locomotion and balance. The topics covered include: Techniques for the measurement of gait and posture, and the standardization of results presentation; Studies of normal and pathological gait; Treatment of gait and postural abnormalities; Biomechanical and theoretical approaches to gait and posture; Mathematical models of joint and muscle mechanics; Neurological and musculoskeletal function in gait and posture; The evolution of upright posture and bipedal locomotion; Adaptations of carrying loads, walking on uneven surfaces, climbing stairs etc; spinal biomechanics only if they are directly related to gait and/or posture and are of general interest to our readers; The effect of aging and development on gait and posture; Psychological and cultural aspects of gait; Patient education.
