An apparatus for imparting substantially oscillatory motion to a subject. The apparatus has a support assembly (12) for supporting the subject and an oscillatory mechanism for defining a path of motion of the support assembly (10), the path having a region of bilateral symmetry with respect to a reference point. An actuator (6) assembly which may be coupled to the oscillatory mechanism enables the subject to control the oscillatory mechanism, as well as to brake and lock the motion of the mechanism. The apparatus may allow for the subject to recline on an articulated support assembly, in which case the equilibrium center of gravity of the support assembly (12) is maintained substantially at the centerpoint of the path of motion regardless of the relative orientation of the articulated segments of the support assembly.
