Non-invasive body contouring is an increasingly popular aesthetic application. Previous data support the efficacy of combined radiofrequency, infrared and skin manipulation for cellulite treatment.
To evaluate the performance of a high-power device (50 W as opposed to 25 W) combining these energies for reshaping and improvement of skin texture/laxity in postpartum women.
Twenty women received five weekly treatments to the abdomen, buttocks and thighs with the VelaShape system. We followed up each patient's weight and nutritional habits. Outcome was assessed using reproducible circumference measurements, digital photography, the physician's scores of cellulite and improvement as well as patient satisfaction. Safety was evaluated by recording subjects' comfort and tolerance.
The overall mean circumferences reduction was 5.4 +/- 0.7 cm (p < 0.001). Significant (p < 0.02) improvement in skin laxity and tightening was noted by both the physician and patients. Treatments were well tolerated with no major safety concerns (one purpura, one mild burn).
The enhanced capabilities of the evaluated system enabled significant results in fewer and shorter sessions without compromising patients' safety or comfort. These data suggest that postpartum reshaping via circumferential reduction and skin laxity improvement can be effectively and safely achieved using a high-energy combination of radiofrequency, infrared and mechanical manipulation.
非侵入性身体塑形是一种越来越受欢迎的美容应用。先前的数据支持联合使用射频、红外线和皮肤按摩治疗橘皮组织的有效性。
评估一种高功率设备（50瓦，而非25瓦）联合这些能量用于重塑产后女性身体及改善皮肤质地/松弛度的性能。
20名女性使用VelaShape系统对腹部、臀部和大腿进行每周一次，共五次的治疗。我们跟踪了每位患者的体重和饮食习惯。使用可重复的周长测量、数码摄影、医生对橘皮组织和改善情况的评分以及患者满意度来评估结果。通过记录受试者的舒适度和耐受性来评估安全性。
总体平均周长减少了5.4 +/- 0.7厘米（p < 0.001）。医生和患者均指出皮肤松弛和紧致度有显著改善（p < 0.02）。治疗耐受性良好，无重大安全问题（1例紫癜，1例轻度烧伤）。
所评估系统增强的功能在减少治疗次数和缩短治疗时间的情况下仍能取得显著效果，且不影响患者的安全性或舒适度。这些数据表明，通过周长减少和皮肤松弛改善来进行产后塑形可以使用射频、红外线和机械按摩的高能组合有效且安全地实现。
