At the end of this blog post, you’ll find a link to the original study, so you can read it yourself, download the PDF, or check the facts. Skip our explanation anytime and jump to the full paper.
❓Who Did This Research and When?
This research was done by three doctors:
-
Eun Jung Choi, Yun Jun Kim, and Sang Yeoup Lee
It was published in a medical journal called JNMA (Journal of Nepal Medical Association) in November–December 2018.
❓Which Country Are the Researchers From?
🇰🇷 South Korea
They worked at:
-
Pusan National University School of Medicine, Yangsan
-
Daedong Hospital, Busan
-
Pusan National University Yangsan Hospital, where they have a special clinic for Obesity, Nutrition, and Metabolism
These are well-known and respected medical centres in South Korea.
❓Who Funded the Study?
The research article does not report any external funding. That means it was done without influence from EMS companies.
❓What Is This Research Specifically About?
The study looked at how EMS (Electrical Muscle Stimulation) affects waist size in adults who had too much fat around the belly (abdominal obesity).
It compared EMS to a fake version called TENS (a type of nerve stimulation that doesn’t cause full muscle contractions).
❓Who Was This Study Done On?
-
60 men and women aged 18 to 65
-
All of them had large waist sizes (over 90 cm for men, over 80 cm for women)
-
None of them exercised regularly
-
They were not on any special diet during the study
❓Which Research Method Was Used?
This was a randomized, double-blind, sham-controlled clinical trial — the gold standard in research.
That means:
-
Participants were randomly put into 2 groups (EMS group and control group using TENS)
-
No one knew which device was real or fake
-
The devices looked the same
Each person used their device:
-
5 times a week
-
66 minutes per session
-
For 12 weeks straight
✅ What Did They Find (Positive EMS Results Only)?
-
EMS Shrunk Waistlines More
-
EMS users lost 5.2 cm off their waist on average
-
TENS users lost only 2.9 cm
-
70% of EMS users lost more than 4 cm off their waist
-
Only 33.3% of TENS users had that result
-
-
Fat Breakdown Increased (Lipolysis)
-
EMS users had higher fasting free fatty acids in blood (FFA), which suggests fat was being broken down
-
This difference was statistically significant (P=0.006)
-
-
No Side Effects
-
No muscle damage
-
No changes in liver or kidney tests
-
No one dropped out due to bad reactions
-
-
High Satisfaction
-
EMS users rated their satisfaction 3.9 out of 5
-
TENS group rated 2.8 out of 5
-
📊 Specific Numbers You Can Picture
| Result | EMS Group | TENS Group |
|---|---|---|
| Waist loss (cm) | 5.2 cm | 2.9 cm |
| Waist loss >4 cm | 70% | 33.3% |
| Free Fatty Acid (fat breakdown marker) | ↑ Significant | — |
| Safety issues | None reported | None reported |
❓Why EMS Could Be Helpful for Certain People?
EMS makes muscles contract and relax just like in a workout. This can:
-
Use up energy
-
Help reduce belly fat
-
Be helpful for those who can’t do regular exercise because of joint pain, fatigue, or mobility issues
❓How Might This Help EMS Users Today?
This study supports that using EMS consistently — even without diet or exercise — might help reduce waist size for some people, without harmful side effects.
If you're using an EMS device like ORIEMS FIT, this shows it's not just a gimmick — it's backed by real science from a university hospital.
