Perception – The intensity is increased so that the patient can feel the
stimulation, but there is not any muscular contraction.
Slight Contraction – Intensity is increased to a barely visible muscular contrac-
tion that is not strong enough to move a joint. When using low pulse rate
settings, this will show as individual twitches. At higher pulse rates there will
simply be increased muscle tension.
Strong muscular contraction is may be useful in spastic muscle group. The DIGI-
TAL EMS can be used in the circumstances to quickly break the spasm. Use a
quick pulse rate, wide pulse duration and set the intensity to visible contraction
(still within patient tolerance). Twenty or thirty minutes of such a tetanized muscu-
lar contraction will generally break the spasm. In all cases, if the patient complains
that the stimulation is uncomfortable, reduce intensity and cease stimulation.
CONTRACTION / RELAXATION
The contraction time and relaxation time of DIGITAL EMS is adjustable.
Stimulation will continue at the setting contraction time and cease also at the set-
ting relaxation time. Then the cycle starts over again – Stimulation, Contraction
and Relaxation.
RAMP
In order to achieve a comfortable exercise and avoid startle because of electrical
shock, each contraction course may be ramped so that the signal comes on gradu-
ally and smoothly. The intensity of electrical current will reach the setting level
within the Ramp time, however, it can not reach the expected level if the contrac-
tion time is less than the ramp time.
TIME DURATION
DIGITAL EMS units are typically operated for long periods of time, with a minimum
of 20 – 30 minutes. However, the time is varied subject to the treatment required.
Please consult your physician before use of DIGITAL EMS.
Chapter 11 : ATTACHMENT OF ELECTRODE LEAD WIRES
The wires provided with the sys-
tem insert into the jack sockets
located on top of the device. Hold-
ing the insulated portion of the
connector, push the plug end of
the wire into one of the jacks (see
drawing); one or two sets of wires
may be used.
After connecting the wires to the
stimulator, attach each wire to an electrode. Use care when you plug and
unplug the wires. Jerking the wire instead of holding the insulated connec-
tor bodymay cause wire breakage.
CAUTION
Do not insert the plug of the patient lead wire into the AC power supply socket.
Chapter 12: LEAD WIRE MAINTENANCE
Clean the wires by wiping with a damp cloth. Coating them lightly with talcum
powder will reduce tangling and prolong life.
Chapter 13 : ELECTRODE OPTIONS
Your clinician will decide which type of electrode is best for your condition. Follow
application procedures outlined in electrode packing, to maintain stimulation and
prevent skin irritation. Use of legally marketed adhesive electrodes is
recommended.
