Stress busters
A new method of reducing anxiety in the dentist's chair is claimed to
be a resounding success
according to a recent study published in the American Journal of
General Dentistry.
The new method uses the Alpha Stim Cranial Electrotherapy Stimulator
(CES).
The Alpha Stim uses a tiny electric current, applied through ear clip
electrodes. This
re-establishes the normal electrical flow in the human body by
producing waveforms which
are similar to those seen in the body when it is in a relaxed state.
The normalisation of
the electrical activity of the cells is claimed to reduce the
physical symptoms of anxiety
resulting in the brain allowing the body to relax in what would
otherwise be a stressful
situation. The results can last for hours or days.

A double-blind placebo-controlled study was performed on 33 randomly
selected dental
patients to evaluate whether cranial electrotherapy stimulation (CES)
is a viable procedure
for reducing anxiety during routine dental procedures. The active CES
treatment group was
significantly less anxious than the placebo group at the conclusion
of various dental
procedures.

Transcutaneous cranial electrical stimulation (TCES): a review 1998.

Montrouge, France.
The Transcutaneous Cranial Electrical Stimulation (TCES) technique
appeared at the beginning of the 1960s and is aimed to act at the
level of the central nervous system. The current, composed of high
frequency pulses interrupted with a repetitive low frequency, is
delivered through three electrodes (a negative electrode placed
between the eyebrows while two positive electrodes are located in the
retro-mastoid region). Due to the characteristics of the current
delivered, shortcomings encountered with previous electrical
stimulation techniques are avoided. The main property of TCES is to
potentiate some drug effects, especially opiates and neuroleptics,
during anesthetic clinical procedures. This potentiation effect
permits drastic reduction of pharmacological anesthetic agent and
reduces post-operative complications. Animal studies performed with
TCES demonstrated that this stimulation releases 5-hydroxy-indol-
acetic acid and enkephalins. Despite numerous clinical and animal
studies performed with this technique for several decades, TCES
mechanisms are not completely elucidated but results obtained without
undesirable effect are encouraging signs to continue investigations
of this particular technique.

AVAILABLE TECHNIQUES: For more than thirty years there has been a
revival of electrotherapy in the treatment of pain. Analgesia by
electrical current is now based on transcutaneous or percutaneous
nerve stimulation, deep stimulation, posterior spinal cords
stimulation, and transcutaneous cranial stimulation. EFFICACY: It is
now scientifically proven that electrostimulation of certain
peripheral fibers and of different structures of the central nervous
system plays an undeniable role in filtration and control of painful
messages. However, precise indications are a prerequisite.
Transcutaneous electrical nerve stimulation is only effective if it
acts on neurogenic pain, only if the nerve pathways to be stimulated
are superficial, and only if the conduction pathways between the area
of stimulation and the superior centers are intact. Neurosurgical
electrostimulation techniques should only be proposed after failure
of simple therapies. INDICATIONS: For acute pain, electrostimulation
of certain intracerebral structures and transcutaneous cranial
electrostimulation may be indicated. Clinicians have a multitude of
electrostimulators at their disposal but generally, the parameters
recommended for their use have no serious scientific basis. The
selected electrical neurostimulator must provide effective nerve
stimulation without causing lesions. Electrostimulation could be
considered as an adjunct to medicinal treatment for pain relief.

The use of cranial electrotherapy stimulation in the management of
chronic pain: A review.
Kirsch DL, Smith RB.
Chairman.
Cranial Electrotherapy Stimulation (CES) has a growing history of
applications in rehabilitation medicine in the United States dating
back to early 1970. As a recognized non-drug treatment of anxiety,
depression and insomnia, CES gained its first major application in
the field of addiction treatment and rehabilitation. By the mid 1980s
research was showing additional important uses of CES in the
treatment of closed head injured patients, and in paraplegic and
quadriplegic patients. The most recent research is showing CES to be
highly effective in the management of chronic pain patients. It may
be elevating the pain threshold due to its stress reducing effects
when anxiety and depression are reduced below clinical levels. Modern
theorists of a pain neuromatrix in the cerebral cortex may provide an
additional basis for understanding CES mechanisms in the control of
pain related disorders.

Potential and current density distributions of cranial electrotherapy
stimulation (CES) in a four-concentric-spheres model.
Ferdjallah M, Bostick FX Jr, Barr RE.
Electrical Engineering Department, University of Texas at Austin
78712, USA.
Cranial electrotherapy stimulation (CES) has been successfully used
for treatment of many psychiatric diseases. Its noninvasive nature is
its major advantage over other forms of treatments such as drugs. It
is postulated that the low electric current of CES causes the release
of neurotransmitters. However, the current pathways have not been
extensively investigated. In the following paper, analytical and
numerical methods are used to determine the distribution of potential
and current density in a four zone concentric spheres model of the
human head when excited by two electrodes diametrically opposite to
each other. Because of the azimuthal symmetry, which is assumed in
this study, a two-dimensional (2-D) finite difference approximation
is derived in the spherical grid. The current density distribution is
projected around the center of the model, where the thalamus is
modeled as a concentric sphere. All dimensions and electrical
properties of the model are adapted from clinical data. Results of
this simulation indicate that, in contrast to previous beliefs, a
small fraction of the CES current does reaches the thalamic area and
may facilitate the release of neurotransmitters.

Physiological and therapeutic effects of high frequency electrical
pulses.
Liss S, Liss B.
MEDI Consultants, Inc., Paterson, New Jersey 07504, USA.
The results of stimulating human subjects with the LISS Cranial
Stimulator (LCS) and the LISS Body Stimulator (LBS) include an
increase or decrease in the activities of certain neurotransmitters
and neurohormones and the reduction of associated pain, insomnia,
depression, and spasticity. The effects were documented in human
subjects with measurements of the serum concentration of the various
agents and assessments of the symptoms being performed before and
after stimulation. The stimulators had a carrier frequency of 15,000
hz, which utilizes the bulk capacitance of the body, and a 15 hz
modulating bioactive frequency. The second modulating frequency
presently used, 500 hz, reduces the energy input to the patient by
half. Significant increases in levels of CSF serotonin and beta
endorphin were recorded post stimulation. There were also elevations
in the levels of plasma serotonin, beta endorphin, GABA and DHEA
together with diminished levels of cortisol and tryptophan.
Concomitant with these changes were significant improvements in the
symptoms of pain, insomnia, spasticity, depression, and headache.

Clinical and experimental evaluation of cranial TENS in the U.S.: a
review.
Taylor DN.
Center for Behavioral Medicine, New York, NY 10028, USA.
A review of studies evaluating therapeutic applications of cranial
TENS in clinical populations reveals frequent use of unreliable self-
report outcome measures, insufficient description of treatment
protocol, invalid double-blind and placebo conditions and often a
lack of adequate description of the electrical parameters used. A
review of the experimental literature indicates that cranial TENS is
capable of modulating central nervous system activity. It is
suggested that the inconclusiveness of the clinical literature may be
due to incomplete research design rather than to the questionable
nature of the treatment, and that cranial TENS merits continued
research.
