Arms and calves have long been a subject of interest in aesthetic medicine. Current surgical and non-invasive procedures focus on sagging skin and fat deposits without targeting the muscles. The aim of this study is to investigate the feasibility of high-intensity focused electromagnetic (HIFEM) technology for arm and calf toning through simultaneous fat reduction and muscle strengthening. In this case study, two subjects received four 20-minute HIFEM treatments of biceps, triceps, and calves, with the outcomes assessed by MRI. The analysis of MRI images showed an average increase in all three muscle groups, biceps muscle mass 17.1%, triceps muscle mass 10.2%, and gastrocnemius muscle mass increased by 14.6%. In addition, the arm fat thickness was decreased by 12.8% on average and the calf fat thickness decreased by 9.9%. The results suggest that HIFEM technology is a feasible modality for both arm and calf toning. However, it will be necessary to continue to validate this outcome in a larger sample size study.

手臂和小腿一直是美容医学关注的焦点。目前的手术和非侵入性程序侧重于下垂的皮肤和脂肪堆积，而不是针对肌肉。本研究旨在探讨高强度聚焦电磁场（HIFEM）技术通过同时减少脂肪和增强肌肉来实现手臂和小腿塑形的可行性。在这项案例研究中，两名受试者接受了四次 20 分钟的肱二头肌、肱三头肌和小腿 HIFEM 治疗，通过 MRI 评估治疗效果。MRI 图像分析显示所有三组肌肉（肱二头肌、肱三头肌和比目鱼肌）的平均肌肉量均有所增加，肱二头肌肌肉质量增加了 17.1%，肱三头肌肌肉质量增加了 10.2%，比目鱼肌肌肉质量增加了 14.6%。此外，手臂脂肪厚度平均减少了 12.8%，小腿脂肪厚度减少了 9.9%。研究结果表明，HIFEM 技术是一种可行的手臂和小腿塑形方法。然而，需要在更大的样本量研究中进一步验证这一结果。J Drugs Dermatol. 2020;19(5): doi:10.36849/JDD.2020.4546.
