Magnetic Muscle Therapy May Boost Mobility for Older Adults

By NATIONAL UNIVERSITY OF SINGAPORE

A decline in functional mobility, loss of muscle strength, and an increase in body fats are often associated with aging.

The recent community study conducted in Singapore involved 101 participants aged between 38 to 91 years old. The researchers found that weekly exposure to very low levels of proprietary pulsed electromagnetic field (PEMF), using the BIXEPS device invented by researchers from the National University of Singapore in 2019, is associated with significant improvements in mobility and body composition after 12 weeks, particularly in older people.

Participants also reported reduced perception of pain after three months of magnetic muscle therapy.

“We are very encouraged by the positive results of this community trial. PEMF-associated improvements were experienced by 85% of participants, irrespective of age, with the greatest benefits reported in older and more frail participants,” says Alfredo Franco-Obregón, associate professor and principal investigator with NUS Institute for Health Innovation & Technology (iHealthtech).

“Our findings suggest that PEMF therapy can produce comparable results to exercise in older persons and therefore holds potential therapeutic value for the older adult population.”

The BIXEPS device targets the muscles in a user’s leg with a specific magnetic signature and creates metabolic activity in the cells similar to when a person exercises. Earlier studies from Franco-Obregón and his team showed that participants who received the magnetic muscle therapy of one leg after knee surgery exhibited improvements in whole body metabolism, predominantly reflected as changes in blood lipid profiles. That is, the effect spread beyond just the treated leg and produced system wide improvements.

The community study was conducted over 34 months, from January 1, 2020 to October 31, 2022. Among the 101 volunteers who participated in the study, 62% were females and 38% were males. Of the participants, 87% had pre-existing mobility dysfunction and 13% were healthy individuals.

The researchers gave participants the proprietary BIXEPS therapy for 10 minutes once a week on alternate legs each week, for a period of 12 weeks. Each participant completed a series of standard performance-based functional tests and indicated their existing acute and chronic pains at the start (week 1) and end (week 12) of the program.

Data on each participant’s body composition—such as weight, skeletal muscle mass, body fat mass, and visceral fat area—were collected before each weekly session.

After eight weeks of treatment, 72% of participants reported improved maintenance of skeletal muscles in conjunction with reductions of total and visceral fats, together with 85% of participants showing improvements in functional mobility after 12 weeks, most significantly in the elderly.

These positive results provide evidence that this PEMF-based technology may represent a valuable therapy to boost conventional geriatric interventions intended to reduce the prevalence of frailty and metabolic disorders in the older adult population.

Very importantly, visceral fat is the inflammatory fat and is associated with a large range of metabolic disorders, including diabetes. Previous studies have shown that people in Southeast Asia hold on to visceral fat more stubbornly than people in other parts of the world despite exercise.

The result is that people in Southeast Asia develop diabetes at a lower body Mass index (BMI) than other demographics. This has posed a real problem for the health industry in South East Asia. “We may finally have a solution to this local health care dilemma in the form of magnetic field therapy,” says Franco-Obregón.

Yvette Cheak, 73, participated in the study in September 2021. She used to have a weak right leg and a buckling knee in the same leg. “Since using BIXEPS, there was less swelling at the ankle and knee, and I became more energetic. My knee is also less painful and doesn’t buckle as much. On some days, I am able to walk at home without a walking stick,” she says.

“Prior to the BIXEPS program, I had a lot of weakness in my legs. It was painful in my hip and feet when I took even a few steps. I could not climb the stairs the normal way, and had to rely on the handrails to balance myself,” says George Teo, age 79. “At the end of 12 sessions, I felt that my leg movement had returned to normal, and I could go up and down the stairs without using the handrails.”

Building on the positive findings of the community study, the team has engaged with research teams in the US and Hong Kong to conduct randomly controlled clinical trials to further validate the benefits for frailty across different aging-populations.

Since 2022, the team has also started a senior-focused study with 200 seniors across four community care centers in Singapore to evaluate how the technology can improve function and alleviate chronic pains. This study is expected to complete in 2023.

Real-world pilot data from existing community programs have also shown promise of better controlled HbA1c—the prevalent marker for diabetes progression—after starting weekly BIXEPS sessions. The research team is currently working with the Singapore General Hospital to conduct a clinical trial to further investigate the possible therapeutic possibility for PEMF-based therapies to manage diabetes progression.

The study appears in the journal Aging.
