Twisting exercise can significantly relieve pain of tennis elbow

Doctors commonly treat the pain with a combination of drugs, ice packs and muscle strengthening exercises.

But now researchers claim that they have invented a novel "twisting" exercise which can significantly reduce the pain.

In fact, it proved so successful that trials were stopped early because it was considered cruel not to give the treatment to all patients.

The therapy involves rotating a small rubber tube 90 degrees while holding it with both hands and allowing only the affected elbow to become twisted.
