A device for exercising the tendons and muscles affected by tennis elbow takes the preferred form of a closed band of elastic material of sufficient circumference to fit around the fingers and thumb of the hand. On the band are four finger loops and one thumb loop. The wearer repeatedly extends the fingers and thumb against the tension of the elastic band and then retracts them. This exercising of the inflamed tendons and muscles ameliorates over time the pain and discomfort of tennis elbow.

Why it's free to use
- Filed October 12, 2000 and granted January 14, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 12, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 12, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
