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!

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.
