Operation of Stiffness Detecting Sensor
The sensor employs two types of sensors; an photo sensor and an electrical skin resistance
sensor for monitoring two physiological factors (pulse rate and perspiration respectively).
If stiffened position is subjected to stimulation of massage, the pulse rate and perspiration
will change accordingly. The sensor monitors such change in those two factors.
A stimulation given to the stiffened or

sore muscle will cause vital reaction
considered to represent a change in
sensation such as better feeling with
comfortable pains. Monitoring such vital
reaction (perspiration and/or change in
Detection
pulse rate) concurrently enables
determination of the effectiveness of the
stimulation given.
The stiffness determined by a change in perspiration and
pulse rate monitored will be indicated in real time on a level
meter of a remote controller.
1;When relaxed, the perspiration tends to decrease.
2;When in normal condition, each physiological
parameter shows less change.
3;When felt stiffened, the perspiration as well as pulse rate tends to increase.
4;When feeling a pain, the perspiration significantly increases and the pulse rate tends
to increase.
In the massage position display, the position where stiffness is detected (=the point needs
to be massaged) will be displayed.
