Abstract：
BACKGROUND: The biophysical interaction induced by low energy pulsed electromagnetic field therapy (PEMFT) on the capillary microcirculation is not well understood. Several studies indicate a significant effect of PEMFT in patients with chronic medical conditions.
OBJECTIVE: The aim of this study was to evaluate the influence of PEMFT on skin microcirculation in healthy volunteers.
METHODS: 15 healthy participants were included. Nine PEMF treatments were applied over three weeks in an 48-hour interval. The PEMFT system (BEMER) was placed beneath one of the participants\' leg with the contralateral side serving as a control. A forty-minute application period was preceded by a 10-minute resting phase. Measuring was done using two Laser Doppler probes (LEA) placed on each anterior lateral thigh.
RESULTS: All outcome parameters including flow, mixed venous oxygen saturation and relative venous hemoglobin showed a significant increase during the experiment when compared to the baseline values of the resting phase in both groups (p < 0.01). Comparing both groups, the measurement values during the experiment did not differ (p > 0.05) except for higher flow values in the control group (P = 0.03). Over time, baseline values of both groups showed no significant difference (p > 0.05).
CONCLUSIONS: We found a significant increase of all measurement parameters during the study compared to the baseline values with no difference between the PEMF and control group.
