Auriculotherapy on Older People With Insomnia

Subjects will then receive MAT. The magnetic pellets will have \~200 gauss/pellet magnetic flux densities on average, with a diameter of 1.76 mm.The experimental object will be applied to the seven selected acupoints as detected by an acupoint detector. Only one ear will receive treatment at a time, and the pellets will remain in situ for two days before the next change.

A laser device (Pointer Pulse™)15 will be used in this study. This device has a wavelength of 650 nm, an average output power of 2.5 mW, an energy density of 1 minute with 0.54 J/cm,2 and a pulse of 10 Hz, which is a common acceptable dosage for clinical use. 16, 17 This application is a low-energy laser therapy (LLLT), in which the energy level emitted from the device is approximately comparable to a teaching pointer. A 1-minute treatment using the continuous mode of the device will be directly applied to the selected acupoints. Laser protective goggles will be provided to the subjects and the researcher for eyes protection
