TensCare Sports TENS 2 Mode D'emploi page 10

For EMS programmes:
Low frequencies (1-10 Hz) have a purifying and
relaxing effect through individual contractions.
Medium frequencies (20-50 Hz) can put a high
level of strain on the muscle, thus promoting the
muscular structure.
Higher frequencies, there is permanent tension
in the muscle (tetany) combined with premature
muscle fatigue. They are therefore preferably
used for elasticity and maximum strength
training.
For TENS programmes:
Pain gate: A high frequency of 110 Hz is good
at blocking pain signals.
Endorphine release: A low frequency of 4 or 10
Hz allows for the release of endorphins, the
body's natural morphine-like substances.
Pulse Width (measured in μs - millionths
•
of a second)
The Sports TENS 2 unit has pulse widths of 20
to 350 μs. Generally speaking, the higher the
pulse width, the more "aggressive" the
stimulation feels, if the pulse width is set high
enough, it will usually
contraction, which is required for an effective
toning of the muscle group selected.
For the TENS programmes (pain relief), it is not
desired to elicit a muscle contraction, however
Pulse Rate is important because different
frequency settings target different nerve groups
and the setting will determine if the "Gate
Theory" or "Endorphin Theory" of TENS will be
used.
Work/Rest
•
All the EMS programmes include a WARM UP,
TRAIN, and COOL DOWN phase. In the TRAIN
phase, the stimulation is intermittent.
elicit a muscle
Once you have reached a comfortable level, 5
seconds after you stop pressing the button, the
intermittent Work/Active Rest phase will start.
For each programme, the unit will go through a
stimulation phase (Work) for 1-40 seconds,
followed by a phase without stimulation (Active
Rest) for a similar time.
This is to allow your muscles to recover from
exercise and avoid fatigue.
During the Work period (W), the unit will
generate contractions, try to contract the
muscle voluntarily at the time to get the best
possible results.
This cycle Work/Rest will continue for the
duration of the programme selected.
W and R are displayed on the screen.
• Ramp
RAMP is the time in seconds taken to move up
and down between zero and the set stimulation
strength (i.e. the time taken to move between
the Work stimulation and the Rest period). The
Sports TENS 2 has a fixed ramp time of 1.5 s
up and 0.75 s down.
Constant and Burst Modes
•
Constant mode is when the sensation is
continuous versus Burst mode when the
sensation, as its name implies, is one of on and
off. Constant mode is often used for acute pain
via Pain Gate effect whereas Burst mode is
useful in chronic pain relief. Burst gives a
combination of Pain Gate and Endorphin
Release, but the squeezing feeling may not be
as comfortable. The stimulation intensity will
need to be relatively high. In Constant mode,
the sensation is continuous and is more of a
tingling pins and needles type.
Modulation Modes
•
Modulation is when either the frequency or
pulse width sweep across range of settings. In
