Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to rehabilitation devices and more specifically it relates to a water rehabilitation device for rehabilitating injuries and facilitating physical exercise.

2. Description of the Prior Art

Water rehabilitation devices have been in use for years. The most common type of water rehabilitation device is comprised of a buoyant structure that provides resistance during downward movement and assistance during upward movement within a body of water such as a pool.

Examples of patented rehabilitation devices which are illustrative of such prior art include U.S. Pat. No. 4,756,699 to Brom; U.S. Pat. No. 3,424,133 to Brady; U.S. Pat. No. 5,102,120 to Lindblad; U.S. Pat. No. 5,338,275 to Chek; U.S. Pat. No. 1,745,280 to Snapp; U.S. Pat. No. 2,094,532 to Glad; U.S. Pat. No. 3,084,355 to Ciccotelli; U.S. Pat. No. 4,988,094 to Beasley; U.S. Pat. No. 4,973,049 to Ciolino; U.S. Pat. No. 4,813,668 to Solloway; U.S. Pat. No. 4,458,896 to Solloway; U.S. Pat. No. 4,300,759 to Caplan; U.S. Pat. No. 3,427,022 to Ward; and U.S. Pat. No. 5,702,331 to Perham.

While these devices may be suitable for the particular purpose to which they address, they are not as suitable for rehabilitating injuries and facilitating physical exercise. Conventional rehabilitation devices are awkward to utilize and typically do not provide any resistance during an upward movement of the individual's leg.

In these respects, the water rehabilitation device according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of rehabilitating injuries and facilitating physical exercise.
