Engineering Minute – Electromagnetic Muscle Stimulator For Rapid Recovery

A team of researchers at National University of Singapore developed a new type of medical device that harnesses an electromagnetic field to speed up muscle recovery. The device, dubbed MRegen, is both non-invasive and painless. It works by tricking the muscle into thinking it is exercising promoting regeneration and faster recovery.

“The device provides a uniform electromagnetic field to a muscle area at a magnitude and pulse duration that reproduces the same regenerative, energetic and metabolic responses as physical activity. The duration of use for the device has been optimised to provide the largest therapeutic effect in terms of muscle equality, function and metabolic stability,” stated leader of the study Associate Professor Alfredo Franco-Obregón from the NUS Yong Loo Lin School of Medicine (NUS Medicine) and the Biomedical Institute for Global Health Research and Technology (BIGHEART) at NUS.

 

From the National University of Singapore article: "MRegen has shown promising results in two human trials conducted between 2015 and 2017. In the first trial, healthy individuals who received 10 minutes of magnetic stimulation in either their right or left leg once a week for five consecutive weeks showed an average of 30 to 40 per cent improvement in muscle strength in both legs. 

The second trial targeted patients who had undergone anterior cruciate ligament knee surgery. In this trial, patients who were treated with MRegen on top of normal rehabilitation therapy experienced a recovery in muscle size and strength in their operated leg four weeks earlier than those who had only received normal rehabilitation therapy. Moreover, Magnetic Resonance Imaging measurements showed that muscle metabolism, one of the strongest indicators of muscle health and regenerative capacity, improved by up to 50 percent in patients who had undergone MRegen’s magnetic field treatment. 

In both trials, field treatment in one leg also consistently appeared to have positively influenced the health of the other leg, demonstrating what is known as a contralateral effect."
