  • Title: Functional magnetic stimulation facilitates gastric emptying.
    Author: Lin VW, Kim KH, Hsiao I, Brown W.
    Journal: Arch Phys Med Rehabil; 2002 Jun; 83(6):806-10. PubMed ID: 12048659.
    Abstract:
    OBJECTIVE: To evaluate the effect of functional magnetic stimulation (FMS) on gastric emptying in able-bodied and spinal cord injury (SCI) subjects. DESIGN: A prospective, nonrandomized clinical experiment. SETTING: SCI and disorder center in a Veterans Affairs medical facility. PARTICIPANTS: Five healthy, able-bodied subjects and 4 subjects with SCI. INTERVENTION: A commercially available magnetic stimulator was used; a round magnetic coil was placed along the T9 spinous process. The intensity of the magnetic stimulation was 60%, with a frequency of 20 Hz, and a burst length of 2 seconds for the gastric emptying protocol. Man Outcome Measures: Rate of gastric emptying and time required to reach gastric emptying half-time (GE(t1/2)) with and without FMS. Data fit into linear regression curve. RESULTS: Accelerated gastric emptying was achieved in both able-bodied and SCI subjects. The mean +/- standard error of mean of the GE(t1/2) at baseline and with FMS was 36+/-2.9 minutes and 33+/-3.1 minutes, respectively, for able-bodied subjects, and 84+/-11.1 minutes and 59+/-12.7 minutes, respectively, for SCI subjects. CONCLUSION: Gastric emptying was enhanced by FMS in able-bodied subjects and was greatly enhanced in SCI subjects. FMS can be a useful noninvasive therapeutic tool to facilitate gastric emptying in humans.
