Vibration stabilizing device

A tremor stabilization device is provided, for example, for assisting in stabilizing tremor in a user suffering from Parkinson's disease or primary tremor. The tremor stabilization device (11) has a housing (17) attachable to a body part of a user, such as a hand, and a rotatable flywheel assembly (23) mounted to the housing (17). The rotatable flywheel assembly (23) comprises a rotatable flywheel (24), a prime mover (25) arranged to rotate the flywheel (24) about a flywheel rotation axis (38), and a gimbal (26) attached to the flywheel (24). The gimbal (26) is pivotally mounted to the housing (17) at hinges (32, 33) formed between the gimbal (26) and the housing (17) and defining a precession axis (34) such that the flywheel (24) can precession relative to the housing (17) about the precession axis (34). The precession axis (34) is fixed relative to the housing (17). The tremor stabilization device (11) further comprises a biasing member (35) arranged to resist precession of the rotatable flywheel assembly (
