Two configurations of static magnetic fields for treating rheumatoid arthritis of the knee: A double-blind clinical trial

Complementary and Alternative Therapies for Cancer

“…Clinical trials have been conducted to test magnetic field therapies in managing pain [39,40], tremor [41], epilepsy [42], and migraine headaches [43]. No data support their role in any illness.…”

Static magnets for reducing pain: systematic review and meta-analysis of randomized trials

“…There was no other condition for which more than 2 randomized trials were available (Table 1 and Table 2). Five trials 8,10,17,31,22 used weak magnets, most of them below the assumed therapeutic strength (believed to be 30 mT), 8 as the control. Meta-analysis of the 9 trials that assessed pain on a 100-mm visual analogue scale (Figure 2) indicated no significant difference in pain reduction between the magnet and placebo groups (weighted mean difference 2.1 mm, 95% CI -1.8 to 5.9 mm, p = 0.29).…”

“…The success of blinding in magnet and placebo groups was not assessed in 18 of the randomized controlled trials. 9,[13][14][15][16][17][18][20][21][22][23][24][25][26]28,[30][31][32] Nonspecific effects may have contributed to the observed effects and may even have been the main factor contributing to the findings in some trials. Six trials 8,10,11,19,27,29 established that equal proportions of participants in the magnet and placebo groups believed they had been given magnetic devices; the 2 groups could thus be assumed to have similar expectations of pain relief.…”

Examination of Long Term Magnetic Fields on Rat Calvarial and Mandibular Bone Mass

“…With respect to the possible health benefits, it has been reported that local SMF stimulation is beneficial for pain management, nerve regeneration (19), imflammation (16), blood flow (2) and united fractures (12). SMF has been used to provide pain relief from neck and shoulder pain and knee pain due to ischemic conditions of the blood microcirculation (11,15,18).…”
