6. INFORMATION ABOUT
THE PROGRAMME
SETTINGS
Each
programme
combination of Frequency and Pulse
Width settings which allow for different
sensations through the electrode pads
and suppress pain in different ways.
• Frequency (measured in Hz -
pulses per second)
PAIN GATE: A high frequency of 110
Hz is good at blocking pain signals.
• Pulse Width (measured in μs -
millionths of a second)
The perfect mamaTENS unit has pulse
widths of 150 to 250 μs. Generally
speaking, the higher the pulse width,
the more "aggressive" the stimulation
feels, and eventually, if the pulse width
is set high enough, it will usually elicit a
muscle contraction, which is typically
not the desired result with a TENS unit.
However, if the pulse width is too low,
the patient may not perceive the
stimulation. 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.
• 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
Endorphin Release, but the squeezing
has
its
own
Gate
and
10
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.
• Active Power Ramp Mode
When pressing the BOOST button in
programme C, the power or level of
intensity during the final contractions
ramps up to give additional short-term
pain relief through a third mechanism
called "Brief intense".

7. PROGRAMMES
7.1. PROGRAMME A
You
can
start
mamaTENS as soon your contractions
start to become regular.
When you switch the machine on, it
automatically selects programme A.
The LCD screen will display A1. This
