the migration of vascular cells and the synthesis of collagen occur,
increasing the speed of recovery. If the cathode (negative electrode) is
placed over the wound, a bactericide effect occurs and the growth of
pathogenic microorganisms is delayed.
Session duration: 15 minutes.
Electrodes' positioning: : form a square above the area to be treated as
shown in Figure 2.
Intensity: to be adjusted between the threshold of perception and pain.
W22 • Kotz Current (non-medical program)
Cable type: TYPE 1 (see Figure 1 - Cable type.)
The Kotz current was discovered by Y. M. Kotz in the 1970s. It is a middle-
frequency current and is used for the strengthening of normally innervated
muscle. A 2.5 kHz interrupted carrier current is used. It is characterised by
10ms packages with 10ms pauses in between; therefore 50 packages of
impulses are supplied per second. The program consists of 10 seconds of
stimulation (with the aforementioned parameters) and 20 seconds of rest.
Total program duration: 10 minutes. The Kotz excitomotor effect occurs in
deep muscles because of their lower resistance. In fact it has been
demonstrated that the electrical impedance skin decreases with an
increase in frequency.
Active channels: CH1 and CH2.
Session duration: 10 minutes, one phase.
Electrodes' positioning: refer to photos from 01 to 22 of the Position
Manual.
Intensity: adjusted in order to produce good contractions of muscles
stimulated at the pain threshold. Maximum adjustable intensity: 50. The
intensity is adjustable only during the 10 seconds of the supply of impulses
and not during the OFF phase.
Neofaradic current
The neofaradic current is used for the stimulation of normal innervated
muscle. It is suitable for treating muscular hypotrophy, and the contraction
of muscles also has a positive effect on bones and articular circulation.
Duration: the W23, W24 and W25 programs are composed of 2 phases:
− The first phase lasts 33 seconds and is for selecting the intensity of
contraction. When the desired level is reached, press the RIGHT
ARROW key to confirm. Next, press the intensity increase key of
