Support device for supporting at least one body part of a user at least in portions, optionally completely, comprising a support body, which comprises at least one support region for supporting at least one body part of a user at least in portions, optionally completely.

A percussive massage device includes a cylinder extending along a longitudinal axis. A motor shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a first pivot offset from the central axis. A pinion gear is coupled to the first pivot. The pinion gear rotates within a ring gear. The pinion gear has a second pivot that rotates about the first pivot. A reciprocation linkage is coupled between the second pivot and a piston that moves longitudinally within the cylinder. An applicator head coupled to a second end of the piston has an end exposed outside the cylinder for application to a person receiving treatment. An actuator selectively rotates the ring gear to cause the applicator head to have a first stroke length and at least a second stroke length.

The system has an accessory control module, comprising computer-executable code stored in non-volatile memory, a processor, a device of a human user, and an accessory configured to communicate with the device. The accessory control module, the processor, the device, and the accessory are configured to receive or obtain multimedia data using the device, create one or more control patterns based on the multimedia data, and drive the accessory using the one or more control patterns. The multimedia data includes at least one selected from the group of text data, sound data, image data, video data, and combinations thereof. The one or more control patterns includes a signal set that drives the accessory to sequentially perform a series of different amplitudes of a predefined act. The predefined act sexually stimulates the human user.

Systems and methods are provided to combine multiple stimulation modalities to significantly increase the effectiveness of non-invasive stimulation. Multiple sensor and stimulation devices and modalities can be combined into a single, compact unit that minimizes the need for additional sensors or stimulation devices. The system features several subunits, referred to as sensory and stimulation devices (SSD), that are integrated into a headphone setup. The system is controlled by a centralized controller that communicates with all of the SSDs and with an external computer system that delivers learning material synchronized with the delivery of stimulations and the collection of user responses based on physiological signals.
