Spherical hand exerciser with off-center weighted core

Abstract

A spherical hand exerciser has a resilient, non-slip exterior with an off-center cavity and a weighted core housed within the cavity. A method of performing physical therapy with the exerciser includes grasping at least one exerciser; and manipulating it around the hand and fingers. The offset placement of the weighted core works stabilizer muscles of the fingers, hand, wrist, and forearm during manipulation, increasing the synergy and workable range of motion of both the flexor and the extensor muscles, allowing for faster learning and better effects.

What is claimed is: 
     
         1 . A spherical hand exerciser with an off-center weighted core, comprising: a resilient, non-slip exterior with an off-center cavity formed therein; and a weighted core housed within the off-center cavity. 
     
     
         2 . The spherical hand exerciser of  claim 1 , wherein the weighted core comprises a metal ball. 
     
     
         3 . The spherical hand exerciser of  claim 1 , wherein the resilient, non-slip exterior comprises an inorganic polymer. 
     
     
         4 . The spherical hand exerciser of  claim 1 , further having dimensions effective for manipulation within a user's hand. 
     
     
         5 . The spherical hand exerciser of  claim 1 , wherein the resilient, non-slip exterior has a predetermined texture. 
     
     
         6 . A method of performing physical therapy, comprising:
 providing at least one spherical hand exerciser of  claim 1 ;   grasping the at least one spherical hand exerciser; and   manipulating the at least one spherical hand exerciser around a hand and fingers.
