INTRODUCTION
Thank you for purchasing the StimChoice 4000 for your pain relief and
muscle training solution. In order to use the device safely, read the complete
manual carefully before using for the first time. Keep this instruction manual
in a convenient place, or store with the device for future reference.
The StimChoice 4000 is a four output channel device and is highly effective
in relieving pain. TENS and EMS are now highly regularly recommended by
doctors, physiotherapists and pharmacists throughout the world.
MEDICAL BACKGROUND
Explanation of Pain
Pain is an unpleasant sensation that can serve a useful purpose by
alerting us to a possible injury or disease. When the body is functioning
normally, pain serves as a warning system that something is not right.
Without pain a person would not know when to avoid danger or seek
medical help. Pain becomes a problem when it continues after treatment
has started or long after an injury is healed.

HOW TENS WORKS
There is nothing “magic” about Transcutaneous Electrical Nerve
Stimulation (TENS). TENS is intended to help relieve pain. The TENS unit
sends comfortable impulses through the skin to stimulate the nerve (or
nerves) in the treatment area. In many cases, this stimulation will greatly
reduce or eliminate the pain sensation the patient feels. Pain relief varies by
individual patients, mode selected for therapy, and the type of pain. In many
patients, the reduction or elimination of pain lasts longer than the actual
period of stimulation (sometimes as much as three to four times longer).
In others, pain is only modified while stimulation actually occurs. You may
discuss this with your physician or therapist.
HOW EMS WORKS
Electronic Muscle Stimulation (EMS) works by sending electronic pulses to
the muscle needing treatment; this causes the muscle to exercise passively.
This device is low frequency and in conjunction with the square wave
pattern allows the stimulation to work directly on the muscle groups.
The goal of electrical muscle stimulation is to achieve contractions or
vibrations in the muscles. Normal muscular activity is controlled by the
central and peripheral nervous systems, which transmit electrical signals
to the muscles. EMS works similarly but uses an external source (the
stimulator) with electrodes attached to the skin for transmitting electrical
pulses into the body. The pulses stimulate the nerves to send signals to a
specifically targeted muscle, which reacts by contracting, just as it does
with normal muscular activity

HOW SPORT MODE WORKS FOR MUSCLE STIMULATION
(EMS SUPPLEMENT)
Neglected for many years, muscle preparation has today become
indispensable for the competitive athlete. In this respect, muscular
electrostimulation is a complementary training technique widely used by an
increasing number of athletes aiming to improve their level of performance.
Increasing the maximum strength of a muscle, developing muscular volume,
increasing the explosive strength of muscles or improving the capacity of
muscle fibers to sustain effort over long periods of time are objectives that
differ according to the sport discipline being practiced.
SPORT stimulation cannot be a substitute for active muscle training but
does represent an attractive supplement. It enables the training of muscles
for which the person has insufficient time to employ the classic training
methods. We recommend this mode for the regeneration and relaxation
programs after a muscle training session.
HOW FITNESS MODE WORKS FOR MUSCLE STIMULATION
(EMS SUPPLEMENT)
Today there are more fitness enthusiasts than ever before, and the
number continues to rise. Apart from some rare individuals who have real
competitive targets, the vast majority have only one goal: to restore or
maintain their body at peak physical condition. Cardio training therefore
alternates with more specific exercise to develop or maintain a toned body.
With this in mind, the desired results may differ according to who is doing
the training. Some would like to increase muscle volume to achieve an
imposing stature (body building) or better muscle endurance to improve
physical comfort during long workouts. Combined with a voluntary physical
activity (aerobic exercise), FITNESS stimulation enables you to obtain a
toned figure. FITNESS stimulation is intended to make healthy muscles
work, it is not suitable for atrophied muscles.

BENEFITS OF ELECTROSTIMULATION
The StimChoice 4000 is designed to be used for temporary relief of
pain associated with sore and aching muscles in the shoulder, waist,
back, neck, upper extremities (arm) and lower extremities (leg) due to
strain from exercise or normal daily activities. It is to be used to stimulate
healthy muscles in order to improve and facilitate muscle performance.
Other benets include:
With a significant improvement in various muscular qualities.
With no cardiovascular or mental fatigue
With limited stress exerted on joints and tendons.
Electrostimulation thereby enables more muscular work
than voluntary activity.
FOR OPTIMUM RESULTS, WE RECOMMEND SUPPLEMENTING
YOUR ELECTROSTIMULATION SESSIONS WITH:
Regular exercise
A balanced and healthy diet
A balanced lifestyle

HOW TO CONTROL AND
REDUCE YOUR PAIN
WHEN SHOULD THE DEVICE BE USED?
Use as soon as your pain begins. Start with one session. If you address your
pain early, it may prevent the pain from becoming worse, or even chronic. It
is better to get pain under control before it increases and may limit your daily
activities.
SETTING THE INTENSITY
Intensity is based upon your level of comfort. Begin the first session with a
low intensity and a short duration while learning how to operate the device.
Therefore, caution should be used when working with maximum intensities.
DO NOT exceed your comfort level.
HOW LONG SHOULD YOU USE THE DEVICE?
It is recommended that you use the device once a day (up to 30 minutes)
for each treatment area. Depending on your pain level, you may need to use
it longer. DO NOT exceed 3 times a day (maximum 90 minutes total). Start
with one session. ALWAYS turn the unit off with pads still adhered to skin.
Rate your pain to check your progress, 1 low to 30 high. Intensity is based
upon your level of comfort. Stop the therapy session if pain has reduced or
stopped. If your pain does not improve and you become sore from over-use,
refrain from treating those areas for 2 days. If this issue reoccurs, reduce the
treatment time and intensity settings for future treatment.
WHAT TYPE OF PAIN IS TENS BEST FOR?
This therapy works best on acute pain because it is localized. Acute pain
occurs in one area for less than three (3) months. If you have chronic pain,
you may have pain in more than one area and for longer than six (6) months.
Chronic pain may be compounded by other issues that this device cannot
address. Remember this device does not cure your pain or the original cause
of the pain. It provides temporary relief or reduction of pain to help you get
back to your normal activity level.
NOTE: All preset programs may feel different to each individual, depending
on body part applied. If the current is too strong, decrease the intensity, and
choose a different preset.
