How does Tenex® Elbow Shock Absorber (ESA) work?

Upon sudden impact or during repetitive action, harmful vibrations travel up the arm where they can cause damage. When worn on the wrist, Tenex® ESA absorbs these vibrations BEFORE they have a chance to reach the soft tissues of your wrist and elbow. A specially formulated liquid metal sealed inside the product, produces a counterwave action that effectively neutralizes vibrations whenever your arm receives a shock.

Our results say that Tenex® Elbow Shock Absorber dampens vibrations better than anything we’ve ever seen.

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.

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.

*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.

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.
