When worn on your wrist, Tenex ESA absorbs 70% of harmful vibrations according to testing conducted at the Massachusetts Institute of Technology and at the University of British Columbia. Use Tenex® ESA to protect yourself from tennis elbow, golfers elbow, carpal tunnel, muscle stress and fatigue!

There is no equal to Tenex® ESA. Shown to reduce vibrations by 50-70 percent, it is clearly superior to the competition. Commercially available products such as braces, straps, bulky supports and racket vibration dampeners can at best claim a 5-10 percent reduction in vibration. No competitors guarantee proof of performance – Tenex® ESA backs its claims with extensive technical and medical reports and a full one-year performance guarantee.

In addition to amateur and professional tennis players and golfers, Tenex® ESA is used by baseball players to reduce trauma to their arms, in pistol practice by shooters, by carpenters, gardeners, keyboarders and mountain bikers. In fact, anyone who needs to protect their arm from repetitive stress. By wearing Tenex® ESA, participants can increase their endurance in competition AND increase their power by enjoying pain free play.

	"The results obtained in all tests are consistent with previous studies on the effectiveness of Tenex® Shock Absorber. In the test study, we witnessed that 90% of the subjects showed significant reduction in the intensity of pain and an increase in flexibility and freedom of movement. We conclude that Tenex® Shock Absorber is effective in the reduction of symptoms of Carpal Tunnel Syndrome. This is a real scientific breakthrough in the treatment of Carpal Tunnel Syndrome and of Repetitive Motion Disorder."

Tennis elbow AKA lateral epicondylitis, repetitive stress disorder, golfers elbow, medial epicondylitis, baseball elbow and, in some cases carpal tunnel syndrome, are all conditions related to inflammation of the soft tissues in the wrist and elbow. Repetitive motion in sports or work, causing repeated shocks to the arm - even micro trauma - can eventually lead to pain from the wrist to the elbow.

Golfers elbow, or medial epicondylitis, is similar to its counterpart, tennis-elbow. The primary differences between these conditions are the location of the pain and the activity that leads to injury. However, both conditions are caused by overuse of the muscles and tendons of the forearm, leading to inflammation and pain around the elbow joint and the main culprit is vibration.

It is considered a type of tendonitis, an inflammation of the tendons. Tendons are connective tissues that attach muscle to bone. Because of the force of the muscle, the points where the tendon attaches to the bone are often pointed protrusions. The medical name of Golfers Elbow (medial epicondylitis) comes from the name of these bony protrusions where the tendons insert, and where the inflammation causes the pain. The pain of golfer's elbow is usually at the elbow joint on the inside of the arm; a shooting sensation down the forearm is also common when gripping objects.

Generally, damage is done at the point where the forearm tendon is anchored to the upper arm bone (humerus) resulting from shock travelling up the arm while, simultaneously, gripping something tightly. The result is microscopic tears in the tendon at the anchor point where inflammation occurs. The forearm muscles are in continual tension due to the opposing action needed by the hand for gripping, the tendon inflammation (tendonitis) is unable to heal.

What is carpal tunnel syndrome?
The carpal tunnel is a bony canal within the palm side of the wrist that allows for the passage of the median nerve to the hand. Carpal Tunnel Syndrome (CTS) is a pinching of the median nerve within the wrist. Pinching or compression of this nerve by the transverse carpal ligament sets into motion a progressively crippling disorder resulting in wrist pain, numbness and tingling in the hand. Pain is accompanied by a "pins and needles" feeling at night, weakness in grip and a lack of coordination.

What can cause carpal tunnel syndrome?
The most common cause of Carpal Tunnel Syndrome is inflammation of the tendons in the tunnel which can normally be attributed to repetitive use of the hand and/or wrist. Repetitive Stress Injuries (RSI) can happen to anyone whose work calls for long periods of steady hand movement, from musicians and dental hygienists to meat cutters and cashiers. RSIs tend to come with work that demands repeated grasping, turning and twisting: they are especially likely if the work requires repetitive vibration, as in hammering nails or operating a power tool. Stressful hand, arm and neck positions - whether from working at a desk, long-distance driving or waiting on tables - only aggravate the potential for damage. A number of sports can bring on Repetitive Stress Injuries. The obvious sports associated with these ailments include both Tennis Elbow as well as Golfers Elbow. Just about any activity that involves repetitive movement, including rowing, skiing, archery, etc. can lead to injury.

Causes of carpal tunnel syndrome and repetitive stress injuries?
Repetitive use of hand/wrist. Long periods of steady hand movement. Repeated vibration. Repeated grasping, turning, twisting.

The principle function of Tenex® ESA is to reduce the harmful vibrations that cause your elbow pain. However, studies have verified that pain reduction is directly correlated with an increase in power. So wearing Tenex® ESA actually does improve your game by allowing you to play both harder and longer.

	"In all muscle-associated testing*, wearing the Tenex® Elbow Shock Absorber resulted in a significant increase in muscle strength and aided subjects in achieving their goal of pain-free racquet sports while playing a much stronger game."
	- Bill Reichelt, Head Trainer, B.C. Lions Football Club and Athletic Therapist *Medical Study testing of Tenex ESA on 40 players for 30 days.

Tenex® ESA is worn on the wrist like a watch just above the wrist bone. It should feel snug but comfortable on your wrist. Do not over tighten. The Velcro strap can be adjusted at both ends. If you have small wrists and still need to shorten it, you may cut off part of the hook ends to further adjust the strap to your wrist size. If you are experiencing pain in both arms, you may wear Tenex® ESA on each wrist. We recommend that you first wear Tenex® ESA all day until you feel a clear improvement. Then wear as needed during work or play.

It may take a few days to notice the healing effect of wearing Tenex® ESA. At first, it will prevent further damage to the inflamed tissues while the natural healing process is underway. Once pain disappears, wearing Tenex® ESA will prevent a recurrence.

Tenex® ESA has been recommended by doctors to alleviate symptoms of tennis elbow particularly in patients who prefer non-invasive treatments. Surgical procedures and cortisone shots present risks and expense to patients. Tenex® ESA is an effective and non-invasive solution to elbow pain whose efficacy increases with continued use.

The effectiveness of Tenex® ESA has been verified in five separate studies conducted by independent researchers. Engineering studies conducted at the Massachusetts Institute of Technology, and at HAKO Research Laboratories, concluded that Tenex® ESA reduces migratory vibrations by 50-70 percent. Clinical testing found a measurable improvement in players’ strength and power attributable to a reduction in inhibition caused by pain. Trial tests of Tenex® ESA on subjects suffering from tennis elbow revealed a dramatic improvement in their condition, and in some cases, complete elimination of the symptoms.

Vibration dampening results were procured from oscilloscope amplitude measurements connected to a piezoelectric sensor and to a computer to average data.

Tenex® ESA uses a UV-treated polycarbonate casing designed to withstand the sun’s rays. It is hermetically sealed so use in water is not a problem. Avoid bringing Tenex® ESA into contact with diesel fuel as it will chemically react with the polycarbonate casing.

We recommend removing the strap and washing it in mild detergent as necessary. The Tenex® ESA casing can simply be wiped off with a damp sponge.

The properties that make Tenex® ESA effective do not diminish over time. However, the strap will eventually wear out and may be purchased separately.
