A Randomized Controlled Trial of the Effects of a Combination of Static and Dynamic Magnetic Fields on Carpal Tunnel Syndrome

Abstract

PEMF exposure in refractory CTS provides statistically significant short- and longterm pain reduction and mild improvement in objective neuronal functions. Neuromodulation appears to influence nociceptive-C and large A-fiber functions, probably through ion/ligand binding.

Pulsed magnetic field versus ultrasound in the treatment of postnatal carpal tunnel syndrome: A randomized controlled trial in the women of an Egyptian population

“…Another research trial applied combined static and dynamic magnetic fields for 4 h per day over two months. There was significant pain reduction, but only mild improvement in objective neuronal functions in the magnetic treatment group versus placebo [37]. This mode of treatment was not appropriate in the current study because of the need to avoid long-term exposure of the newborn to PEMF at home.…”

The change of HCN1/HCN2 mRNA expression in peripheral nerve after chronic constriction injury induced neuropathy followed by pulsed electromagnetic field therapy

“…PEMF with magnetic field at the intensity of 200μT could increase the latency to thermal stimulation in land snails [22] and mice [23]. Magnetic field has been applied to improve neuronal recovery after injury, to lessen neuropathic pain [24], due to the stimulation of the central and peripheral neural systems. Pulsed magnetic field (PMF) has been used to treat the peripheral nerve injury for years, for it can accelerate the functional recovery of injured peripheral nerve [25].…”

“…PMF can ameliorate the hyperpolarization of after potentials and delayed depolarization of nerves [26]. PMF can also promote peripheral nerve regeneration in different experimental animal models [27; 28], because axons of neuron are sensitive to electrical and magnetic stimulation [24]. However, PEMF had no effect on the change of expression of HCN1 and HCN2 mRNA after CCI.…”

Complementary and Integrative Medicine for Neurologic Conditions

“…39,40 Several small studies have shown improvements in electrodiagnostic testing and pain scales with the use of magnetized wristbands. 41–43 However, the research is preliminary, has methodological concerns, and only provides limited clinical information for treatment recommendations. Although magnet therapy cannot be recommended as treatment at this time for CTS, further research is important to better understand efficacy, dose, and duration.…”
