The human body is known to produce magnetic and electrical fields, with every organ, cell, and molecule having its own field of energy. While the heart is the most powerful source of electromagnetic energy in the human body, producing the most energetic field of all its organs, there is evidence to suggest that skeletal muscles also produce magnetic fields. This discovery has led to the development of Magnetomyography (MMG), a method used to interpret skeletal muscle contraction mechanisms and gain a better understanding of skeletal muscle physiology. Additionally, devices like MRegen use magnetic fields to increase muscle strength and promote regeneration, making them useful in therapeutic settings.

What You'll Learn
Magnetic fields and muscle contraction
Magnetic fields have been observed to have an influence on muscle contractions. The study of magnetic fields from skeletal muscles is considered a valuable physiological measurement. The recording of magnetic fields from this tissue can provide additional details concerning muscle gradation force mechanisms, which is important in clinical and sports applications.
The human body produces electric and magnetic signals, and the measurement of these signals can be used in medicine to determine the activity of living tissues. For example, in the nervous system, cells communicate with each other by sending electrical signals along nerve axons. In muscles, small variations in potential values are essential for muscle contraction, allowing for movement, walking, holding objects, and heartbeats.
Magnetomyography (MMG) is a method used to interpret skeletal muscle contraction mechanisms from the magnetic fields produced by ionic currents. MMG is based on the measurement of the magnetic field generated by skeletal muscle fibers under contraction. The magnitude of the MMG signal is lower when compared to other biological tissues and can range from pico (10−12) to femto (10−15) Tesla (T).
Research has shown that exposure of skeletal muscle cells to a complex spatiotemporally modulated magnetic field triggers a significant increase in cytosolic Ca2+ levels, which is critical for muscle contraction. This increase in cytosolic calcium is caused by the emergence of eddy currents induced by alt-magnetic fields with moderate strength and short exposures.
Additionally, a prototype device called MRegen has been developed to use magnetic fields to "fool" muscles into thinking they are being used, thereby increasing muscle strength. This device has been shown to improve muscle strength and metabolism and is especially useful in reducing muscle degradation when physical activity is not possible.

Magnetism and muscle recovery
While exercise is the most effective way to build muscle, there are situations when people, especially those who are frail or injured, need some assistance. In such cases, a device that uses magnetic fields to trick muscles into thinking they are being used can be beneficial. This machine, known as MRegen, creates a uniform electromagnetic field around the muscle area, simulating the regenerative, energetic, and metabolic responses that occur during physical activity.
MRegen has been shown to be effective in improving muscle strength and size, with trial participants experiencing a 30-40% increase in muscle strength and a faster recovery in muscle size and strength compared to those who only received regular rehab therapy. The device is particularly useful in preventing muscle degradation when physical activity is not possible. Additionally, MRegen has been found to improve muscle metabolism, a crucial indicator of muscle health and regenerative capacity.
The concept of using magnetic fields for muscle recovery is not new. Some studies have suggested that measuring magnetic fields from skeletal muscle tissue can provide valuable insights into muscle physiology and gradation force mechanisms, which is crucial in clinical and sports applications. This approach, known as Magnetomyography (MMG), aims to interpret skeletal muscle contraction mechanisms by analysing the magnetic fields produced by ionic currents.
Furthermore, the use of magnetism in muscle recovery has been explored in the form of magnesium supplementation. Research has shown that magnesium supplementation can effectively reduce muscle soreness, improve recovery, and have a protective effect on muscle damage. Magnesium works by blocking calcium uptake, helping muscles relax after intense contractions during exercise. It also impacts other nutrients, such as activating vitamin D, which is essential for maintaining muscle health and performance.

Magnetomyography (MMG)
The development of MMG was motivated by the exploration of the electrophysiological behaviour of the uterus prior to childbirth. It was also influenced by the discovery of magnetic fields produced by ionic currents in electrically active tissues, such as the brain and heart. MMG has been found to be particularly useful in monitoring uterine contractions during pregnancy and has the potential for applications in the rehabilitation of traumatic nerve injuries, spinal cord lesions, and entrapment syndrome.
MMG signals are typically collected using superconducting quantum interference devices (SQUIDs) or optically pumped magnetometers (OPMs), which have improved significantly in recent years. The magnitude of the MMG signal is lower compared to other biological tissues, such as the heart, and ranges from pico (10^-12) to femto (10^-15) Tesla (T). This small magnitude presents challenges as it can be easily affected by magnetic noise from the surrounding environment.
The progress of MMG has been slow due to the technical challenges associated with detecting weak biomagnetic signals and the high cost and bulkiness of the required equipment. However, recent advances in technology have improved the fidelity, temporal, and spatial resolution of non-invasive biomagnetic signal detection. Efforts are also being made to develop miniaturized, low-cost, and room-temperature magnetic sensors to enhance the accessibility and applicability of MMG.

Magnetic stimulation (MS)
TMS has shown potential in the diagnosis and treatment of various neurological and mental health conditions, particularly in the central nervous system. The effects of TMS depend on the frequency, duration, and intensity of stimulation, with single or paired pulse TMS causing neurons in the neocortex to depolarize and discharge an action potential. This can result in muscle activity, referred to as a motor evoked potential (MEP), when used on the primary motor cortex. TMS can also be used to measure the connection between the primary motor cortex and the peripheral nervous system, evaluating damage related to neurological insults.
One of the advantages of TMS is its ability to stimulate cortical tissue without causing pain, as seen in transcranial electrical stimulation. The risks associated with therapeutic repetitive TMS (rTMS) are higher than diagnostic TMS, and adverse effects generally increase with higher-frequency stimulation. However, adverse effects of TMS are rare and include fainting and seizures.
TMS has been found to be beneficial in several areas. Firstly, it can be used to treat depression and chronic pain, as it may promote the release of dopamine and control neurotransmitters involved in pain. Secondly, it can help with muscle tightness (spasticity) caused by multiple sclerosis when combined with physical therapy. Thirdly, TMS can be used after a stroke to promote motor recovery and improve difficulty swallowing by stimulating the motor cortex. Lastly, it may be beneficial for auditory hallucinations associated with schizophrenia by targeting the temporoparietal cortex.

Magnetic therapy
While magnetic therapy products, such as bracelets, jewelry, mattresses, and creams, are widely available, the effectiveness of magnetic therapy in treating specific conditions is not yet fully understood. Some studies have shown potential benefits in pain relief, particularly for musculoskeletal conditions and osteoarthritis. However, the existing research is limited, and many studies have inconclusive or conflicting results.
One of the challenges in studying magnetic therapy is the difficulty in conducting unbiased studies due to the inherent detectability of magnetisation. This makes it hard to effectively blind participants and assessors, which can lead to exaggerated treatment effects. Additionally, the magnetic fields produced by the devices used in magnetic therapy are relatively weak and may not have a significant impact on the body's internal processes.
Despite the lack of conclusive evidence, magnetic therapy has gained popularity, with an annual global industry worth over a billion dollars. While generally considered safe for most people, it is important to exercise caution when using magnetic therapy, especially for individuals with pacemakers, insulin pumps, or other devices that may be affected by magnetic fields.
Although the effectiveness of magnetic therapy in treating specific conditions remains uncertain, there are emerging technologies that utilise magnetic fields in innovative ways. For example, the MRegen device, developed by a team at the National University of Singapore, uses magnetic fields to "fool" muscles into thinking they are being used, which can help maintain muscle strength and metabolism during periods of reduced physical activity. This technology may have applications in space exploration to counteract the effects of long-term space travel on bone density.
