[Pain relief by low-intensity frequency-modulated millimeter waves acting on the acupuncture points]

Analgetic effect of low-intensive frequency-modulated millimetric waves (MW) was studied in mice with formalin induced nociceptive behavior reaction (licking of defeat hindpaw). MW were applied to the acupoint E 36 of the defeat hindpaw. The following MW were used: 60 GHz (1) and 118 GHz (2) which were modulated by 4 Hz; noise MW within the range of 42-95 GHz (3) and 90-140 GHz (4) which were modulated in accidental order by frequencies 1-60 Hz; combinations of fixed frequencies with noise - 60 GHz + noise 42-95 GHz (5) and 118 GHz + noise 90-140 GHz (6). All used MW combinations suppressed licking of the defeat hindpaw and increased duration of sleep and eating. The strongest analgesia was achieved in series 1-3 (42.4-69.7%), the weakest in series 6 and 4 of the experiment (12.2-19.7%).
