A ball-massaging board (14) molded out of plastic with a curved surface to comfortably support a person's spine in the supine position. Attached to the surface of board (14) are a number of rubber balls (15/16) that have a bolt head (18) bonded inside them, and a threaded portion (19) protruding outside them. Threaded portion (19) is inserted through a hole (21) in board (14), then secured in place by a lock nut (20). Because hole (21) is larger in diameter than the diameter of threaded portion (19) balls (15/16) are able to freely spin about the surface of board (14). Balls (15/16) are able to spin and roll simultaneously along the surface of board (14) while remaining attached to board (14). As an individual lies on the massaging board (14) and swivels his or her hips a combined spinning and rolling effect is created by balls (15/16) on the user's back and neck, simulating a real life massage. The user experiences deep penetrating massage therapy by lying on the entire diameter of balls (15/16) which effectively relieve trigger points throughout the entire back, shoulders, and neck, while rehabilitating various muscles.
