Frequently Asked Questions
These are the questions we're asked most by potential customers and current users.
What size Shock Blocker should I wear?
When shopping online, the best way to find your size is by using the Shock Blocker Sizing Chart. Based on testing, we’ve found that most adult males fall within the medium-large range, while most adult females are in the small-medium range.
When in doubt, we say it’s better to go a size up. This ensures the ring will fit around your finger. An optimal fit will have the ring loose enough to rotate, but not so much that it easily falls off.
When shopping in person, you can size each finger that requires a Shock Blocker individually by placing it into the sizing hole on the package. The finger should move easily into the hole. Make sure that you select a size that is neither too tight nor too loose for each finger.
Has Shock Blocker been tested?
Yes. The most recent and largest nationwide study delivered outstanding results: More than one hundred tennis players who suffered from tennis elbow for an average of three years played tennis wearing a Shock Blocker for four-five weeks. The median age was 44 and the gender mix was roughly equal. Almost 70% had had a diagnosis of tennis elbow made by a doctor. Severe pain was experienced by 43%. All had tried multiple common remedies without satisfaction.
During the test period, the average number of times played was eight; seven while wearing the device.
Nearly two thirds (65%) reported that Shock Blocker was very effective in reducing their tennis elbow pain and discomfort. 83% said that the device “exceeded or met” their expectations. Most interestingly, 60% of the participants reported at least a 50% improvement in their level of play!
Of the participants who suffered severe pain, nearly half (44%) reported improvement of pain to a level considered to be mild.
This study result was consistent with a previous study result and shows why so many people are excited about this product. The recent study showed good results despite the fact that the participants on average used the device only 7 of 8 times playing.
For which conditions is Shock Blocker useful?
Reducing and preventing the pain of Tennis and Golfer’s Elbow.
What if I have failed other treatments, including surgery?
Shock Blocker has been found to be very helpful in many cases of Tennis or Golfer’s Elbow that failed all known treatments, including surgery.
What activities that cause/aggravate Tennis/Golfer's Elbow will Shock Blocker most likely help?
Activities that involve tightly gripping sports equipment, tools, handles, household items, etc. This includes using a tennis racquet, golf club, baseball bat, hockey stick, etc. to hit a ball or puck; rowing a boat with an oar or paddle, or steering a tiller; grasping a steering wheel or the grips on a motorcycle, bicycle, scooter, snowmobile, jet ski or water ski; grabbing a handle of any type (wheelbarrow, lawnmower, garden tool, etc.); working out with gym equipment, barbells, chin-up bars, etc.; climbling a rope; housecleaning that involves a broom, mop or vacuum cleaner; holding the handlebars on a walker or wheelchair; using a hairdryer, and wielding an axe to chop down a tree or fight a fire. And many other activities.
Will Shock Blocker help when the problem is active and my elbow is hurting?
The short answer is yes. Shock Blocker will enable most people to resume the activity that caused the elbow problem and allow it to heal. Some people, however, will need to rest the elbow until it has healed, or at least improved substantially, before resuming the inciting activity with the Shock Blocker.
Will Shock Blocker cure my condition?
Yes…and no. Shock Blocker will help keep the problem from recurring and permit micro-tears in your tendons to heal. However, even after healing, once-damaged tendons will never be normal again and will be prone to re-tearing even during “normal” daily activities.
In which situations is the Shock Blocker unlikely to work?
Shock Blocker has not been evaluated for the treatment of other elbow problems aside from Tennis and Golfer’s Elbow. If you are uncertain as to what condition is causing your elbow pain, then please consult with your doctor first. Sometimes, Tennis or Golfer’s Elbow may be the result of over-activity of the wrist. Shocker Blocker will not help in this situation. Likewise, Tennis or Golfer’s Elbow may be caused by excessive use of the fingers such as when typing. Similarly, Shock Blocker will not help in those situations.
What other situations or problems might be helped by Shock Blocker?
Some people with finger tendonitis have benefited by using Shock Blocker.
Who should not use Shock Blocker?
People who are subject to ulcers of the hands that do not heal well, and people whose skin conditions may be aggravated by pressure on the skin should not use this device. Shock Blocker users should be certain that they suffer from Tennis or Golfer’s Elbow. There are many other causes of elbow pain. Some of these conditions will not be helped by the Shock Blocker and some may be aggravated by continued physical activity. If you have any questions, please consult your doctor before using Shock Blocker.
When should I wear two Shock Blockers on the same finger?
If you have a very strong grip, on occasion, your Shock Blocker may tear or break while being used. To greatly decrease the chance of breakage, we suggest that you wear two Shock Blockers on the same finger with the flat part of each ring pressing against the other.
What if the Shock Blocker ring hurts my hand?
First, check to be sure that the size selected rests on your finger loose enough to easily rotate or even move a bit up or down the finger – but not loose enough to slip down beyond the middle joint of the finger while using the device.
If the fit is correct and you still experience pain, place a small amount of athletic tape on your finger prior to slipping on the Shock Blocker, but before engaging in physical activity (if your finger is moist with sweat, the tape may not hold). Do not use so much tape that the Shock Blocker feels tight on your finger.
Will the Shock Blocker work if it rotates or moves along my finger?
The Shock Blocker is designed so that it can rotate around the finger while also moving up and down a bit. This dual movement will help avoid finger abrasion and allow Shock Blockers on adjacent fingers to interweave. However, the ring should not be loose enough to easily slide over the middle knuckle. A simple solution is to wrap some athletic tape around the finger where the Shock Blocker will be worn. Do this prior to use, because once your finger becomes moist with sweat, the tape will not adhere properly.
What are the potential side effects of using Shock Blocker?
The ring may squeeze your finger if it is not sized properly, so a size should be chosen that it is slightly loose on the finger. The device may irritate or abrade the skin beneath it. And a very small percentage of people may find the ring uncomfortable to wear while playing tennis.
How do you use Shock Blocker for Tennis or Golfer’s Elbow…or for both?
If you suffer Tennis or Golfer’s Elbow, lay your arm on a table with the palm up. Press on the painful area with the opposite hand and move each of your fingers on the affected arm up and down, noting which one(s) trigger pain at the elbow. If you have both Tennis and Golfer’s Elbow, repeat the procedure for the other side of the elbow. After noting which fingers trigger elbow pain, wear a Shock Blocker on each of the affected fingers with the curved, smooth part close to or touching the webbing between the fingers. If your skin is sensitive to irritation, place athletic tape around finger(s) prior to slipping on Shock Blocker.
Resume your favorite activities and enjoy them without elbow pain!
Is Shock Blocker safe to use with other products that claim to help Tennis/Golfer’s Elbow?
Shock Blocker can be used with other devices, including elbow braces.
How can I prolong the life of my Shock Blocker?
Proper care is simple. Regularly clean the ring with plain water or a mild soap and air dry. It should be kept dry at all times. Extreme heat or cold should be avoided. Avoid contact with jagged or sharp objects since if a tear is started it may progress to a complete tear or breakage. If you have a particularly strong grip, you can avoid breaking your Shock Blocker by wearing two devices on the same finger.
In addition to this device, what else can I do to help Tennis Elbow when playing tennis?
Over the years there have been many devices, treatments, exercises and surgical procedures that have been promoted for treating tennis and golfer’s elbow. Many of these devices, treatments, etc. can be used in conjunction with the Shock Blocker. For instance if you think that an elbow sleeve or brace is helping your elbow condition, then you can certainly continue to use that appliance along with using the Shock Blocker.
History & Science
What is the Shock Blocker back story?
The device was conceived to enable one of its inventors to continue to play tennis despite suffering severe lateral and medial and epicondyle tendinosis (Tennis and Golfer’s Elbow). His elbow pain was unresponsive to nearly all known treatments, including braces, injections, high dose ultrasound treatment and even surgery. The new prototype worked instantly. It was initially thought that the device functioned by absorbing shock from the tennis ball, but it was soon realized that by lifting up certain fingers, it sharply decreased tension on related tendons.
Increasing the girth of the racquet grip did not duplicate the effect of the device. To accommodate a single finger-tendon pairing, the grip would have such a large circumference that the other fingers would not be able to exert enough force to hold the racquet properly.
The realization that tennis professionals rarely suffer tennis elbow is consistent with the theory that the device works primarily by decreasing tendon tension, since tennis pros generally strike the ball while holding the racquet with a more relaxed grip than amateurs.
How does Shock Blocker work?
In brief, it works 2 ways: First, Shock Blocker is made from Sorbothane®, a space-age material with exemplary shock absorbing ability. By placing it right at the source of impact – your finger – it dampens much of the vibration. Secondly, Shock Blocker utilizes the TTR System (Tendon Tension Reduction) which decreases the shock or kinetic energy reaching the elbow.
What makes Shock Blocker unique?
Many reasons: Based on the above explanation, it gets to the source of the problem, aids in healing the elbow by decreasing the chance of a shock wave reaching the elbow with full force, and it keeps shock waves below the threshold that can cause micro-tears. Plus, it acts as a preventative for recurrence once the problem has improved.
What material is Shock Blocker made of?
Sorbothane®, a highly flexible and resilient material with tremendous shock absorbing capabilities. Sorbothane® is used in many applications in the medical and industrial fields.
Have there been any problems with this material?
Not that we are aware of. Allergy to Sorbothane® would be extremely rare but certainly should be considered if a person develops blistering or redness or swelling beneath the Shock Blocker. In that case the use of the Shock Blocker should be discontinued at once and a doctor consulted. It is possible for a Shock Blocker to break if exposed to extreme heat or cold, and therefore it should not be kept or stored in those environments. Also if the Shock Blocker wearer is very physically strong, the ring may tear or break with use, and can be avoided by wearing two Shock Blockers at the same time. The two Shock Blockers should be stacked on the same finger with the flat part of each pressing against one another.
