This paper systematically evaluates the efficacy and safety of the domestic electromagnetic muscle toning device called NEOSCULPT, which is based on high-intensity focused electromagnetic field (HIFEM) technology for abdominal and gluteal contouring.

A prospective self-controlled clinical trial was conducted in two phases (gluteal and abdominal), each involving 32 healthy subjects. All subjects received targeted electromagnetic interventions twice a week for 30 minutes each session over a period of 4 weeks. Body circumference measurements, MRI imaging analysis, body composition analysis, and blood and urine biochemical tests were performed at baseline, at the end of the intervention, and one month post-intervention. Adverse events were recorded.

Following the gluteal intervention, the average overall hip circumference increased by 2.2% (P<0.001), and the average waist-to-hip ratio in females improved by 6.7% (P<0.01). Following the abdominal intervention, male subjects showed a 6.3% increase in abdominal muscle area (P<0.01) and a 10.4% decrease in fat area (P<0.001); female subjects showed an 11.8% increase in abdominal muscle area (P<0.001) and a 7.5% decrease in fat area (P<0.01). The overall efficacy rate for muscle enhancement and fat reduction was 80%, with an average reduction of 1% in total body fat percentage (P<0.001) and an average reduction of 8.2% in abdominal subcutaneous fat thickness (P<0.001). These effects were generally maintained during the follow-up period. Apart from a physiological increase in creatine kinase levels post-exercise, no abnormal fluctuations were observed in blood and urine biochemical parameters. Only one case experienced changes in renal function, which recovered after treatment, with no serious adverse events occurring.

The NEOSCULPT electromagnetic muscle toning device significantly increased participants' gluteal circumference and improved gluteal firmness, while simultaneously achieving dual effects of abdominal muscle growth and fat reduction, with excellent clinical application safety. These findings provide high-quality evidence-based support for the clinical application of domestically produced non-invasive muscle enhancement devices.
