How PEMF Therapy Works

PEMF devices utilize low-frequency electromagnetic fields to stimulate the mitochondria within your body’s cells, enhancing their function and promoting natural healing mechanisms. They can be used to treat various conditions, including chronic and acute pain, inflammation, arthritis, sports injuries, and mood disorders. In addition, PEMF therapy has been shown to accelerate bone healing and support bone density for people living with osteoporosis.

By deeply penetrating a broad range of tissues, PEMF treatment targets the underlying causes of musculoskeletal pain and discomfort, typically delivering long-lasting results. The guide highlights that the technology does not require direct skin contact and can be used to treat large areas of the body.

So, How’s It Different from FSM & TENS?

PEMFPod explains that, in contrast, Frequency Specific Microcurrent (FSM) therapy applies low-level electrical currents to specific tissues for targeted pain relief. As such, it is especially beneficial for treating headaches, migraines, neuropathy, fibromyalgia, muscle soreness, and other localized issues.

Conversely, Transcutaneous Electrical Nerve Stimulation (TENS) is applied via electrodes to block pain signals traveling to the brain and stimulate the production of ‘feel-good’ hormones—endorphins. The guide notes that its effects are immediate yet generally short-term, so regular treatment is needed to maintain results. Applications include menstrual cramps, backache, sciatica, and post-surgical pain.

Other factors you should consider when opting for electrotherapy treatment include cost and accessibility. TENS units, which are often more economical, and PEMF systems are widely available for home use, whereas FSM therapy is predominantly administered by trained professionals. Furthermore, PEMFPod emphasizes the importance of consulting a healthcare professional who can advise you on potential side effects and contraindications.
