Skin Vibration clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Skin and Acupuncture Needle Vibration Behaviors Through Observation

Start date: May 2015
Phase: N/A
Study type: Observational

Skin tremor induced by artery pulses are usually sensed by doctor's fingers in Traditional Chinese Medicine(TCM). On the other hand, vibration of acupuncture needle was also stated by Huang Di Nei Jing (Yellow Emperor). However; the characteristics of skin tremor and its correlation with vibrating acupuncture needles, how the skin tremor and vibration of needles varies from area to area, are not yet clarified.In this study, the abovementioned issues will be investigated experimentally through non-invasive method. About 10 healthy volunteers, aged 20~65, will be recruited. The investigators will measure the needle and the skin tremor by video optical microscopy. The variation of skin tremor and needle vibration and their spectra will be analyzed digitally. The model correlating skin tremor, needle vibration and basic physiological parameters will be constructed.The fact that the skin tremor and the needle vibration come from the same origin is expected. However; due to the leverage effects and different dynamical responses to the source vibrations at different frequencies, needle vibration might exhibit some difference from skin vibration in their power spectra. This study should be able to construct a clear model of the possible vibration sources such as heartbeat and breathing, the area dependence of vibrations, the correlation between the skin and the needle vibrations, and the correlation with other physiological parameters.
