The only absolute contraindication for use of a PEMF device is placing an active applicator over implanted electrical devices like pacemakers, cochlear implants, intrathecal pumps, etc., because the magnetic ﬁeld can shut the device off.
PEMFs are contraindicated in organ transplant patients. This is because these people are on immune suppression medications to prevent organ rejection. We do not want to risk adversely affecting the immune suppression/rejection process. There is a chance that PEMFs may actually stimulate or activate a more aggressive rejection process.
Safety of PEMFs has not been established in pregnancy, although there is no evidence of harm.
PEMFs should be used with caution in Grave’s disease or in the case of active bleeding.
High intensity PEMFs should be used with caution or with professional guidance in people with implanted metals, such as joint replacements, dental implants, mechanical heart valves, metal stents, or metal staples in blood vessels.
Do not use high intensity PEMFs to breast implants or prolonged treatments to the chest area in women with breast implants. High-frequency PEMFs beyond 100 Hz is probably also not desirable given the risk of agitating the plastic or silicone in breast implants, resulting in possible thinning and risk of leakage. On the other hand, breast implants are often associated with significant inflammation with adhesion formation. In that case PEMFs could be quite helpful, but it might be best to avoid prolonged exposures beyond an hour at a time and higher frequencies.
