Objectives: This study introduces an initial evaluation of
a novel High-Intensity Focused Electromagnetic (HIFEM)
technology. The primary goal is to quantify any
effects the treatments may have on abdominal tissues, as
well as to establish hypotheses for future research of this
technology.

Materials / method: Twenty-two patients received four abdominal
treatments using the EMSCULPT device (BTL Industries
Inc., Boston, MA). Anthropometric evaluations were
recorded and digital photographs were taken at baseline,
at 2 months, and at 6 months post-treatments. The MRI
without contrast determined by verterbras T12 and S1
(FIESTA and FSPRG sequences) was used to measure
dimensions in coronal cross-sectional images of abdominal
muscle and fatty tissues, in order to assess any anatomical
changes induced by the application.

Results: Analysis of the same MRI slices verified by
tissue artifacts showed a statistically significant (all
P<0.0001) average 18.6% reduction of adipose
thickness, 15.4% increase in rectus abdominis muscle
thickness, and 10.4% reduction in rectus abdominus
separation (diastasis recti) as measured from the medial
border of the muscle 2 months post-treatment. More
significant improvements were observed in patients with
BMI 18.5–24.9 (classified as “normal”). MRI data from
6-month follow-up suggest the changes can be preserved
in longer term. Tape measurements showed on average
3.8 cm subumbilical.

Conclusion: MRI, considered as a highly precise diagnostic
method, revealed simultaneous muscle growth, fat
reduction and reduced abdominal separation at 2 months
and at 6 months post treatments, unrelated with dieting.
Further research should investigate the exact physiological
processes which stand behind the tissue changes observed
in this study.

Objectives: This histological study investigates the difference between simultaneous and
consecutive application of monopolar radiofrequency with targeted pressure energy
on porcine skin.

Introduction: The cosmetic appearance of skin is substantially influenced by the
organization of connective fibers and underlying subcutaneous tissue. It has been
previously documented that radiofrequency and pressure energies alone are able to
improve skin appearance; however, detailed histological evaluation should be done
to determine their synergistic effect.

Materials / method: In a total of four weekly abdominal treatments, simultaneous emission of
the energies was applied to two pigs (12 minutes per session); additionally, two pigs
were treated consecutively (12 + 12 minutes per session). The 5th pig served as a
control subject. Biopsies were obtained at baseline, after the 4th treatment, and at
1-month follow-up. Primary outcomes were to document changes of dermal and hypodermal
tissues.

Results: In the treated subjects, the amount of collagen and elastin fibers increased
significantly (P < .001). At follow-up, simultaneous application showed a significantly
higher increase in collagen and elastin fibers (by 59% and 64%, respectively), when
compared to consecutive. Thickness of the dermis increased more in the pigs treated
simultaneously (+848.8 μm/50.17%; P < .001). Treated tissue also showed the upper
part of dermis to be rich in blood vessels and better organized interlobular septa in
hypodermis. No significant change was observed in the control subject.

Conclusion: Simultaneous application produces significantly more profound changes,
when compared to consecutive treatment. Further research is needed but our findings
represent a new potential treatment of various skin conditions like cellulite or
laxity.
