[Increases of intracranial pressure and changes of blood flow velocity due to acupressure, needle and laser needle acupuncture?] / Litscher G, Wang L, Schwarz G, Schikora D. |
| Abstract |
BACKGROUND: Pressure on the acupoints St.7 and SJ.22 can lead to significant, reversible increases in intracranial pressure (ICP) in patients with elevated ICP. OBJECTIVE: In this study, we investigated whether changes in cerebral parameters in healthy volunteers can also be registered, when the mentioned acupoints associated with ICP, are stimulated. SUBJECTS AND METHODS: We investigated a total of 34 volunteers (24 females, 10 males) and a 15-year-old intensive care patient after severe head injury. The mean age of volunteers was 25.2 +/- 3.4 years (range 20-35). Stimulation was performed using acupressure techniques, manual needle and laser needle methods. We evaluated the main parameter of mean blood flow velocity in the middle cerebral artery (left and right) as well as the pulsatility index. In addition, near infrared spectroscopy and blood pressure parameters were registered. RESULTS: Acupressure, manual needle acupuncture and laser needle acupuncture partially led to significant changes in the main goal values. CONCLUSION: Acupressure as well as acupuncture (needle and laser needle) can evoke reproducible functional changes in the brain. These accompanying effects are not to be ignored, in particular in patients with increased ICP. |

Objectivation of cerebral effects with a new continuous electrical auricular stimulation technique for pain management. / Szeles JC, Litscher G. |
| Abstract |
AIMS: The electrical point stimulation system (P-STIM) reflects a new, miniaturized system for pain therapy through ear acupuncture. For this reason, ultrathin needles were applied at the ear. The needles stimulate the acupuncture areas at the ear using electrical impulses, which come from a little generator applied behind the acupunctured ear. METHODS: This study describes continuous, non-invasive measurements of near infrared spectroscopy (NIRS) and multidirectional transcranial Doppler sonography in two healthy females (aged 23 and 27 years) during stimulation with P-STIM, for the first time. RESULTS: The results of the pilot measurements have shown that electrical point stimulation using the new electrical stimulation system on eye acupuncture points is able to modulate the mean blood flow velocity (vm) of the supratrochlear artery. These effects were present using a stimulation frequency of 100 Hz. A lower increase in vm was found in the middle cerebral artery. In addition, stimulus induced, quantifiable and reproducible alterations of the regional cerebral NIRS parameters were be detected. CONCLUSION: For the first time, P-Stim allows intermittent ear acupuncture stimulation for up to several days in combination with complete mobility for the patient. |
