RAAS (Biphasic)
Rapid Agonist Antagonist Sequencing
(RAAS) is proposed to mimic muscle-firing
patterns of healthy individuals. It uses
the electrical stimulation of sensory and
motor nerves to achieve a skeletal muscle
contraction using an electromyogram
— derived functional pattern. It is used
extensively for neuromuscular reeducation
and treatment of muscle disuse atrophy.
WAVEFORM SPECIFICATIONS
PARAMETERS
Phase
Duration
Expressed in
μ
s, is the
time it takes to complete
one phase of a pulse. The
length affects the type of
nerve recruited.
Frequency
In a pulsed current, the
Frequency refers to the
number of pulses that
occur in a one second
period of time and is
denoted in (Hz) or Pulses
Per Second (pps).
Burst
Duration
The time elapsed from
the beginning to the
end of one burst, and is
denoted in (ms)
Pattern
Frequency
The Pattern Frequency
refers to the number of
the sequential pulse train
pattern be repeated in
a one second period of
time and is denoted in
(Hz).
