TY - JOUR T1 - ARe magnets effective for pain control? AU - Fontanarosa PB, Burkhart CG, Burkhart CN Y1 - 2000/08/02 N1 - 10.1001/jama.284.5.561 JO - JAMA SP - 564 EP - 566 VL - 284 IS - 5 N2 - To the Editor: Dr Collacott and colleagues1 found that magnets were ineffective in treating low back pain. Inasmuch as electromagnetic fields are known to alter biomolecular DNA synthesis, cell proliferation, membrane calcium fluxes, and cell surface properties in vitro,2 they may nonetheless be beneficial in treating patients with various disease states. The principal site of biophysical interaction leading to cell functional alterations with magnets is most likely the lipid membrane surface, where electromagnetic radiation may affect the ability of ion pump enzymes to move calcium, sodium, and potassium ions across the cell membranes.3 SN - 0098-7484 M3 - doi: 10.1001/jama.284.5.561 UR - http://dx.doi.org/10.1001/jama.284.5.561 ER -
