Description

Attachment of small-sized permanent magnets to the body surface is expected to increase regional blood flow, which possibly improves stiff shoulder, muscle pain, and the general condition. We produced a spectacle frame using a magnetic substance and evaluated the improvement in regional blood flow in the areas pressed by the frame and its possible effects on pain in the temples due to skin compression by the frame and the general condition (such as stiff shoulder and muscle pain) due to impaired regional blood flow. When an 800-gauss permanent magnet was placed at a site 5 mm below the skin, the subcutaneous blood flow showed a 2-fold - 2.5-fold increase. Blood flow was measured using a laser doppler flowmeter. A U-type magnet (magnetic intensity of 800 gauss at a site 5 mm from the pole) was used. Even when the polarity was changed (N pole, S pole), a similar increase in blood flow was observed in all magnetic pole directions. These fingings suggest that use of a magnet in the frame of glasses increases blood flow irrespective of the magnetic pole direction, resulting in improvement in impaired blood flow due to pressure by the frame.
