Anorexia nervosa (AN) is a complex disease that involves malnutrition and a profound depletion in muscle mass. The thickness of the adductor pollicis muscle (APM) has been proposed as a new anthropometric technique to estimate muscle mass, check early changes, and assess its evaluation. This study aimed to evaluate the accuracy and validity of the APM thickness in a cohort of malnourished patients with AN when checking local mass gain. The Doppler ultrasound maybe an affordable and useful method to discriminate all tissues around the APM area.
A prospective cohort study was conducted of 31 malnourished patients with AN who were admitted to the Regional Eating Disorders Unit for treatment, including re-alimentation. Anthropometric measurements were taken, including arm circumference, triceps skinfold thickness, arm muscle circumference, body mass index, and APM thickness of both hands. Simultaneously, a Doppler ultrasound was performed in the same area, measuring and discriminating fat, skin, and muscle tissues around the APM.
Nutritional improvement is accompanied by fat, but not muscle gain in the hand in the adductor pollicis area of patients with AN. A Doppler ultrasound can accurately discriminate between tissues around the APM.
APM thickness reflects the addition of two different muscles plus fat and skin; therefore, this tool is not reliable to assess APM mass.
神经性厌食症（AN）是一种复杂的疾病，涉及营养不良和肌肉大量减少。内收拇指肌（APM）厚度已被提出作为一种新的人体测量技术，以估计肌肉质量，检查早期变化，并评估其评估。本研究旨在评估 APM 厚度在营养不良的 AN 患者队列中的准确性和有效性，以检查局部质量增加。多普勒超声可能是一种经济实惠且有用的方法，可区分 APM 区域周围的所有组织。
对 31 名因营养不良而患有 AN 的患者进行了前瞻性队列研究，这些患者因治疗包括重新进食而被收治到区域饮食失调科。进行了人体测量测量，包括臂围、三头肌皮褶厚度、臂肌围、体重指数和双手的 APM 厚度。同时，在同一区域进行了多普勒超声检查，测量和区分 APM 周围的脂肪、皮肤和肌肉组织。
营养改善伴随着 AN 患者手部 APM 区域的脂肪增加，但肌肉没有增加。多普勒超声可以准确地区分 APM 周围的组织。
APM 厚度反映了两个不同的肌肉加上脂肪和皮肤的增加；因此，该工具不可靠，无法评估 APM 质量。
