Handheld rotator cuff exercise and treatment device

A method for treating shoulder rotator cuff problems comprising:

• using a handheld centrifugal exercise device comprising:
• a single hand grip handle having a longitudinal axis and a length from an upper end to a lower end sufficient to accommodate a width of an intended user's hand when gripping said hand grip handle;
• a freely rotating pivot shaft extending longitudinally and coaxially from said upper end of said handle a distance less than said length of said handle;
• a cable port extending perpendicularly through said pivot shaft at a distance spaced from said upper end of said handle less than length of said pivot shaft;
• a flexible, semi-rigid cable extending through said cable port in slidably adjustable fashion, said cable having an outer weighted portion extending from a first side of said pivot shaft to an outer end and a weighted member secured thereto, and an inner unweighted portion extending from a second opposite side of said pivot shaft to an inner unweighted end;
• said outer weighted portion of said cable being longer than said inner unweighted portion thereof;
• a lockable and, unlockable member associated with cable port for temporarily locking said cable in cable port such that said cable's position may be varied to make said weighted portion either longer or shorter when said lockable and unlockable member is unlocked, and may be fixed at a desired length ratio of said outer weighted and inner unweighted portions of said cable relative to said pivot shaft when said lockable and unlockable member is locked;
• said hand grip being free of encumbrances which might interfere with said cable when said weight is being moved by a user in a circular or elliptical orbit about said upper end of said handle;
• gripping said handle with an arm of the shoulder having rotator cuff problems;
• moving said handle in small circles with a straight, unbent arm to rotate said weighted cable and said weighted member around said freely rotating pivot shaft which minimizes wrist motion, at a sufficient speed that said weighted cable and said weighted member on the longer outer portion of said cable spins in large circles, exerting a centrifugal force on the shoulder having rotator cuff problems;
• varying the centrifugal force exerted by said outer weighted member to a level comfortable to the user by selectively unlocking said lockable member in said cable port and pulling on said inner unweighted portion of said cable to in the direction to make the weighted portion of said cable shorter, or alternatively pulling on said weighted portion of said cable in the direction to make said weighted portion longer.
