A device comprises at least one processor and a memory comprising instructions that when executed by the at least one processor cause the at least one processor to: generate a first signal that causes a vibration device to vibrate, the vibration device being in force-transmitting contact with a first anatomical element; receive, from a sensor, a second signal based on sensed vibration in a second anatomical element proximate the first anatomical element; and determine, based on the second signal, an amount of mechanical coupling between the second anatomical element and the first anatomical element.

Disclosed are embodiments of a vibrating bed which allows a particular person to induce a customized vibrational pattern that they find particularly therapeutic. In certain embodiments, the bed has a water mattress, a carriage for the mattress, a hardwood frame to support the carriage, a transducer for producing different vibrational patterns in the mattress, a vibrotactile amplifier for controlling the transducer, a computer for controlling the amplifier and software on the computer for producing sounds of particular frequencies to induce the vibrational patterns in the water mattress.

Systems and methods for exerting forces on a body, including a support structure defining a space and a plurality of surface contacting units that are configured to exert force upon the body, such that the weight is distributed away from the primary weight bearing regions to non-weight bearing regions of the body, or vice versa, without exerting significant shear or frictional forces on surfaces of the body. The systems and methods may be used to exert forces to cause fluid shift in different compartments of the body. Applications include treatment of various disease conditions including pressure ulcers, heart failure, high blood pressure, preeclampsia, osteoporosis, injuries of spine and to slow microgravity-induced bone and muscle loss. The systems and methods may be used to simulate gravity, weightlessness or buoyancy, in rehabilitation medicine. The system may include a chair, bed, a wearable suit or an exoskeleton.
