Does this brace help tennis elbow?

A counterforce strap like this presses on the forearm muscles below the elbow, which many people find reduces pain during activity. It supports rather than cures, so rest and strengthening exercises still matter.

Which arm does it fit?

It is unisex and fits either arm. The strap wraps around the upper forearm, so you can wear one on each elbow or keep the second as a spare.

Can I wear it while playing tennis?

Yes. It is designed for moderate activity and is slim enough to wear during play. Adjust it snug but not so tight that your hand tingles or goes numb.

Hand wash only in cool water and air dry. Do not machine wash or tumble dry, since heat can damage the neoprene and hook-and-loop closure.

Is it the same as a elbow sleeve?

No. A sleeve covers the whole elbow with compression, while this strap targets the tendon attachment below the elbow. Some people use a strap for tennis elbow and a sleeve for general soreness.
