Compex – The Company
▪ A Swiss Based Company founded in the 1980’s
▪ Developed a niche for electrotherapy products ▪ Health ▪ Clinical treatments of Orthopedic
and/or Neurology ▪ Rehabilitation
▪ Training▪ Part of DJO Global, Inc.▪ Global provider of high-quality,
orthopedic devices▪ Products used for rehabilitation, pain
management and physical therapy.
Theory and Principles of Electrostimulation (EMS)▪ EMS is the application of electric
current to stimulate bone or muscle tissue for therapeutic purposes, such as facilitation of muscle activation and muscle strengthening (Mosby, 2009)
▪ The impulses are generated by a device and delivered through electrodes on the skin in direct proximity to the muscles to be stimulated.
▪ The impulses mimic the action potential coming from the central nervous system, causing the muscles to contract.
Theory and Principles of Electrostimulation (EMS)
Nerve pathway from brain to
muscle
A muscle can’t tell the difference between a voluntary contraction triggered by the brain or through a muscle stimulator. Excitatio
n occurs directly on the motor nerve
Workout without cardiovascular fatigue
Workout without stressing joints
Theory and Principles of Electrostimulation (EMS)▪ The electrical impulses can also
excite the sensory nerve fibres to obtain an analgesic or pain relieving effect.
▪ The stimulation of the tactile sensory nerve fibres blocks the transmission of pain by the nervous system.
▪ The stimulation of another type of sensory fibres creates an increase in the production of endorphins and, therefore, a reduction in pain.
▪ With pain relief programmes, electrostimulation can be used to treat localised acute or chronic pain as well as muscle pain.

Clinical Studies - #1 - Soccer
In a French study by Billot, Martin, Paizis, Cometti & Babault (2010)Compex was used to investigate the effect
of a 5-week electrostimulation
(EMS) training program.
Focus on muscular strength (Quadriceps), kicking velocity, sprint,
and vertical jump performance in soccer
players.
20 male soccer players were
randomly divided into two training
groupsEMS group received
EMS on the quadriceps muscles during 5
weeks (3 sessions of 12 minutes per week) and soccer training.
Control group only had soccer training.
The athletes were tested after 3 and 5 weeks training
Significant improvements in
Quadriceps muscle strength as well as in
ball speed performance.
Improvements were not seen in the control
group.
Clinical Studies - #2 - Swimming
In a Californian study by Neric, Beam, Brown, & Wiersma (2009)
Aimed to evaluate the effect of active recovery
with electrical stimulation versus
submaximal swimming recovery and passive
resting recovery.
Subjects were swimmers from high school and
collegiate swim teams who trained on a year
round basis.
Testing
EMS was applied to primarily the to the
muscles in the region of the anterior thighs and
lower back.
Blood lactate levels were tested before and
immediately after a 200yrd swimming sprint, as well as after 10 min (‘mid-recovery’) and 20 min (‘post-recovery’).
Results of both groups reveal
Blood lactate levels were most decreased with the submaximal swimming recovery
method.
EMS recovery also produced significantly
better lactate reduction compared to resting
recovery.
Clinical Studies - Effectiveness
▪ Study #1 - Improved strength and performance in healthy individuals and athletes▪ It can also infuse variability into
the training program, which might enhance the motivation of some players.
▪ Recommended use for injured athletes to attenuate or eliminate detraining effects.
▪ Study #2 - Enhanced muscle recovery▪ Using EMS to reduce muscle
and blood lactate when athlete has limited access to other active recovery modalities (e.g. pool, stationary bike or opportunities to run or walk)
▪ Using EMS to produce muscle contractions while otherwise resting may be of benefit in helping reduce muscle and blood lactate before subsequent performance.
Conclusions
▪ EMS is intended to complement a workout routine, not replace it. ▪ Just as vitamins are intended to
supplement a good diet▪ Compex Systems work in conjunction with
a traditional training regiment to help competitive athletes achieve the highest level of performance possible.
▪ EMS is a very effective way to make muscles work: ▪ With significant improvement in different
muscular qualities▪ Without cardiovascular or mental fatigue ▪ With limited stress placed on the joints and
tendons. ▪ EMS allows a greater quantity of work
to be done by the muscles compared with voluntary activity.
