Stimulation Modes
decrease to zero. After a set time this cycle is repeated. Both outputs are active
simultaneously, with stimulation intensity changes in phase. This format is the
normal exercise mode for related muscle groups requiring stimulation at the same
time e.g. Elbow and finger extensors.
Overlapping

ramp up
Channel A is the first to ramp up to the maximum pulse width. While A is still on,
channel B ramps up as well, after 8 seconds. When B reaches maximum pulse
width channel A starts to ramp down to zero. Channel B continues and channel A
ramps up again. When A is at maximum channel B ramps down. Channel A then
continues and B will ramp up again and the sequence repeats. Overlapping mode
is used for shoulder subluxation exercise. One electrode pair is placed over the
anterior and posterior deltoid muscles and the other over the supraspinatus and
middle deltoid muscles. The first pair of muscles lifts the humerus into the glenoid-
humerus socket while the second pair maintains it in that position while the first
pair is resting.
To avoid unexpected changes in muscle contraction, only adjust the stimulation
intensity while the yellow LED next to the intensity control is lit.
