The characteristics of the pulsed electro-magnetic field (PEMF) delivered by the device (Aculife Magnetic Wave device, SMW-A01, Innohealth Technology Co., Taiwan) used in the magnetic therapy group. (A) single pulse; (B) multiple pulse. The actual output values (showing the range in figure) may be different depending upon the output adjustments (intensity, power mode) as well as the individual skin impedance.
