tenex ESA faqs

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.

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 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.

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. One pain disappears, wearing TENEX ESA will prevent a recurrence and support rehab activites. 

TENEX ESA has been recommended by doctors and physical therapists 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. 

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. 

No. It weighs 1.25 ounces or 36 grams in total. So it is no heavier than an average watch.

Over the course of time (and sales of over 1 million TENEX ESAs) feedback from customers clearly indicate that ESA is a considerably more effective alternative to reduce tennis-elbow pain and inflammation versus braces, creams, bands & wraps, gels, hot & cold packs, magnetic products, medical patches, neoprene sleeves, and TENS units. 

Users often cite that they barely know the ESA is there versus forearm bands and compression sleeves. Countless customers have reported that the chronic tennis elbow conditions which had haunted them for years were completely gone.

You might have expected this one as the name suggests. “Lateral epicondylalgia” literally means pain on the “outside of the elbow”. It can be caused by sports or activities that require repetitive movement of the wrist such as tennis, pickleball, golf, or even typing or playing piano. The muscles that attach to the bump on the outside of the elbow can pull on the bone causing inflammation. When tennis elbow become chronic though, the pain lasts even after the inflammation has gone away. This is why cortisone injections don’t always help. In tennis and pickleball, causes can include:

  1. Playing too much without enough rest
  2. Trying to hit the ball too hard or with too much spin
  3. Bad equipment: strings or racquet don’t dissipate forces
  4. Bad form – hitting the ball with your arm instead of your body

The goal is to improve the strength and flexibility of your forearm muscles, so you won’t be bothered with tennis elbow again. Your physical therapist may also teach you ways to change your tennis or pickleball stroke or other activity that is causing your elbow troubles. PT can also help improve blood flow to the tendons, which don’t get the same level of blood and oxygen supply as muscles normally receive. Exercises that improve blood flow will improve healing, too. 

TENEX ESA comes with a full one-year warranty. If after 30 days of using our product you are not completely satisfied with its performance, you may return it to us for a full refund. If any breakage occurs, it will be immediately replaced. Please contact us at info@tennis-elbow.com to receive return protocol with shipping address.
