Abstract: Wrist, hand, or arm support devices are provided. The support devices include a support member having a top surface and a front surface. The top surface is oriented at either a parallel angle or a non-parallel angle with respect to a work surface. The front surface curves upon itself to form either a symmetric or an asymmetric arc. Preferred versions of the support devices described herein include at least one of a top surface oriented at a non-parallel angle with respect to the work surface or a front surface that curves upon itself to define an asymmetric arc. Mounting members for connecting the support member to an operating surface are also provided. The support devices described herein permit an operator to comfortably rest his or her hand on the support devices while directing procedures toward non-centered portions of work objects.
