Transcutaneous electrical nerve stimulation or TENS is a therapy designed to reduce the pain experienced from tennis elbow, the procedure involves applying a small electrical current to the affected area, TENS supposedly works by stimulating the nerve endings, thus reducing the pain experienced due to tennis elbow. Another theory suggests that electrical stimulation produces endorphins that help reduce the pain. Again there is not scientific data to support either claim, and people might experience pain loss due to placebo more than anything else.
Some people have claimed to have achieved reduction in pain, by having the affected area being gently vibrated. Again this may or may not work for all people and such is not a conventional technique in treating tennis elbow.
By directly applying calculated pressure in small circular motions, the affected area can experience greater blood flow, and the muscles may relax. However messaging the affected area might be painful sometimes, in which case no further message therapy is recommended.
Often called body works, manual therapy involves a trained professional carefully exercising the injured parts, and actually attempting to fix the marginally displaced bones, or tendons back in there place. This technique is often confused with replacing dislocated joints back in their sockets, manual therapy has nothing to do with the surgical technique just mentioned. The idea behind manual therapy is to slowly mobilize the elbow, and to improve the blood circulation in the elbow. The over all effectiveness of manual therapy in the treatment of tennis elbow is yet unknown, however many people have reported to have been positively affected by manual therapy.
Irrespective of the techniques involved, if a patient feels that he wants to try therapy that is not in medical terms conventional, or feels that conventional medical techniques are not working for him. Then he could try one of the methods that are listed above, but he should be aware that some of the techniques listed might do more bad than good.
