A massage device (10) for manipulating a user (12) includes a support member (14) and a manipulator (16) carried by the support member (14). The manipulator (16) is adapted to engage and apply a shear force to the user (12). The manipulator (16) is rotatable about at least one axis (20) relative to the support member and a brake (18) operably connected to the manipulator (16) selectively adjusts rotation of the manipulator (16) about the at least one axis (20) so that the shear force applied to the user (12) by the manipulator (16) is adjusted. In automatically controlled embodiments, a controller (36) adjusts the braking force according to signals received from a detector (34) to prevent or reduce slippage of the roller (16) and to dynamically control the magnitude of the shear force applied to the user (12). In manually embodiments, an operator adjusts the braking force to a fixed magnitude or dynamically adjusts the braking force to control the shear force applied to the user (12). |
