Vasodilation
and Promoted Healing
of Chronic Ulceration by TNS
The well known Norwegian doctor, Birger Kaada, MD - has
in recent years performed several research works, primarily
on Vasodilation induced by TNS. A secondary effect
- viz. Promoted Healing of Chronic Ulceration was discovered
and may well prove to become another major finding.
Dr. Kaada suggests that the burst stimulation releases a
vasodilating agent, not previously found.
ELECTRODE PLACEMENT
Negative black electrode
is to be placed on the web between the 1st and 2nd metacarpal
bones of a hand. Positive white electrode is to be
place on the ulnar edge on the same hand.
TYPE OF STIMULATION
Acupuncture like
stimulation (bursts) of 2 Hz, and an amplitude of 15-30
mA. The amplitude is individual and is suggested to
be increased until local visible contractions occur without
producing pain. Note that after about 5 minutes, stimulation
usually the amplitude can be increased, as a regional
blockade is established.
DURATION AND
FREQUENCY OF STIMULATION
3 daily sessions
each of 30-45 minutes duration. Subsequent to skilled
instruction the method is ideal for home use, with regular
ambulatory check ups.
ETIOLOGIES
Raynaud's disease,
Diabetic Polyneuropathy, and chronic ulceration of various
etiology i.e. Neuropathy, Arteriosclerosis, Varices, Thrombophlebitis,
Decubitus, and Scleroderma.

INCREASED SKIN
TEMPERATURE OF COLD EXTREMITIES WITH ACUPUNCTURE LIKE STIMULATION
The following figures
show the immediate effect of AP-stimulation on a hand as
described above - on a cold left 5th toe (skin temperature
before stimulation: 24° Centigrade). The increase
during the stimulation to about 34° Centigrade, is a dramatic
10° Centigrade. This level is sustained for about
four hours, where after the skin temperature quickly returns
to the initial level. Note that the pain disappears
for the same period of time. Note also that measurements
on body regions of normal skin temperature show only a slight
increase of 0.5 - 2 degrees C.
PROMOTED HEALING
OF CHRONIC ULCERATION
The following 3 figures
show the decrease of size of ulcers. The time of healing
is dependant on the size of the ulcer, and on whether the
treatment is interrupted or not. Ordinate is the size
of the ulcer in mm² or cm³. Abscissa is time in weeks.
You can try this
technique using the ELPHA II 3000 Muscle and Nerve
Stimulator.
To verify its effectiveness
use the SC-911 or T3
Skin Temperature sensors.
