OBJECTIVE: To determine differences in peripheral and cardiovascular autonomic function between individuals with acute musculoskeletal injury (<1 week) and healthy controls. METHODS: Autonomic cardiovascular modulation, baroreceptor sensitivity, skin conductance, and peripheral skin temperature were obtained in 6 subjects with acute musculoskeletal injury and 6 age- and sex-matched controls. Power spectral analysis was performed on both beat-to-beat R-R intervals and continuous systolic blood pressure (SBP) peaks.
Autonomic nervous system (ANS) response to acupuncture has been investigated by multiple studies; however, the brain circuitry underlying this response is not well understood. We applied event-related fMRI (er-fMRI) in conjunction with ANS recording (heart rate, HR; skin conductance response, SCR). Brief manual acupuncture stimuli were delivered at acupoints ST36 and SP9, while sham stimuli were delivered at control location, SH1. Acupuncture produced activation in S2, insula, and mid-cingulate cortex, and deactivation in default mode network (DMN) areas.
BACKGROUND: Qi vacuity (QV) is defined by traditional Chinese medicine as a loss of energy in the human body. An objective method for detecting QV was not available until recently, however. The automatic reflective diagnosis system (ARDK) is a device that detects human bioenergy through measuring skin conductance at 24 special acupoints on the wrists and ankles. METHODS: This study used the ARDK to measure skin conductance on 193 patients with QV and 89 sex- and age-matched healthy controls to investigate whether the device is useful in detecting QV.
Electroacupuncture According to Voll (EAV) was used to monitor the effects of qigong practice on therapeutic balancing of subjects. In EAV the electrical conductance of the skin above individual acupuncture points is measured using low voltage and current. Diagnosis depends on measuring the relative electrical conductance and its time dependence. An important diagnostic criterion of degeneration of an organ is an indicator drop which occurs during the measurement when the conductance decreases from an apparent maximum value and then levels off.

OBJECTIVES: Electrodermal measurements with a Ryodoraku instrument were used to monitor the effects of a 2-day qigong workshop on the body energy of participants. METHODS: Measurements were made of the relative electrical conductivity of 24 acupuncture points on the wrists and feet of 29 subjects. Each subject was measured in the morning and afternoon of each day, and the subjects served as their own control.
BACKGROUND: Despite the popularity of touch therapies, theoretical understanding of the mechanisms of effect is not well developed and there is limited research measuring biological outcomes. AIMS: The aim of this study was to test a framework of relaxation or stress reduction as a mechanism of touch therapy. METHODS: The study was conducted in 1996 and involved the examination of select physiological and biochemical effects and the experience of 30 minutes of Reiki, a form of touch therapy.
Sixty female college students were exposed to a stressful stimulus and treated by therapeutic or physical touch. Groups were compared on levels of physiological response through electromyographic, skin conductance, and peripheral skin temperature measures. The hypotheses predicted that the therapeutic touch group would remain more relaxed than the physical touch group. None of the hypotheses were confirmed using a one-way analysis of covariance.
Four volunteers judged eight levels of thermal stimuli induced by a Hardy dolorimeter, varying in intensity from extremely painful to a low level seldom even perceived. Half of the 406 stimuli were applied during acupuncture and half either before insertion or after removal of the needles.
The inhibitory component of the skin against given electrical current, also called as the electrical skin resistance, is subject to change in response to many factors, especially pain. In order to find out more definite relationship between pain and skin resistance, one should make measurement in the state devoid of any external disturbing stimuli to get the "basal skin resistance (BSR)", which is known to be different from point to point on body surface.
