respective frequency determines which types of muscle fibre preferably react.
Slow-response fibres tend to react to lower pulse frequencies up to 15 Hz,
while fast-response fibres only respond to frequencies over approx. 35 Hz.
With pulses of approx. 45-70 Hz, there is permanent tension in the muscle
combined with premature muscle fatigue. Higher pulse frequencies can
therefore preferably be used for elasticity and maximum strength training.

3.3 Pulse width

Pulse width is used to indicate the duration of an individual
pulse in microseconds. Pulse width also determines the
pene tration depth of the current whereby in general, the
following applies: a greater muscle mass requires a greater
pulse width.

3.4 Pulse intensity

Setting the degree of intensity is individually dependent
on the subjective feeling of each individual user and is
determined by a number of parameters such as application
site, skin circulation, skin thickness as well as quality of
electrode contact. The actual setting should be effective but should never
produce any unpleasant sensations such as pain at the site of application.
While a slight tingling sensation indicates sufficient stimulation energy, any
setting which leads to pain must be avoided.
With prolonged application, readjustment may be necessary due to time
adjustment processes at the site of application.

3.5 ON and OFF time

ON time describes the stimulation time of the cycle in seconds, i.e. the length
of the cycle in which pulses are delivered to the body. OFF time, on the other
hand, indicates the length of the cycle (in seconds) which is stimulation-free.

3.6 Cycle-controlled pulse parameter variation

In many cases it is necessary to cover the entirety of tissue structures at the
site of application by using several pulse parameters. With the Digital TENS/
EMS unit, this is done by the existing programmes automatically making a
cyclical pulse parameter change. This also prevents individual muscle groups
at the site of application from getting tired.
With the Digital TENS/EMS unit there are useful presettings for current
para meters. During the application, however, you do have the possibility of
changing pulse intensity at any time and, with individual programmes, you
can also alter pulse frequency beforehand in order implement the application
which is the most comfortable or promises the most success for you.
