Abstract: An electronic device for percussive massage therapy is described. The device includes a reciprocating member configured to move at any number of different amplitudes and frequencies. In one example of the device of the present invention, the device is configured with a number of gears which permit amplitude to be varied between a great number of amplitudes within a predetermined range. In another example of the device of the present invention, a threaded stroke adjustment apparatus is positioned at the front of the device, and may be rotated in a first direction to increase stroke, and may be rotated in a second direction to decrease stroke. Amplitude and frequency may be adjusted in real time. In yet another example of the device of the present invention, stroke adjustment is achieved by moving an eccentric drive axle within an eccentric drive unit by way of rotation of a ring gear.

Abstract: A combination applicator and adapter (“applicator/adapter”) is removably attachable to a percussive massage device. The applicator has a plurality of fixed applicator heads that can be applied directly against the body of a subject being massaged to provide a first massage effect. A corresponding plurality of removable applicator heads can be positioned over and attached to the fixed applicator heads. The removable applicator heads are applied against the body of the subject being massaged to provide a second massage experience.

Abstract: Disclosed herein are therapy systems including a rolling element. The therapy systems can include a plurality of individually activatable therapy elements disposed on the rolling element. The therapy systems can include a sensor disposed on the rolling element and configured to detect a portion of the rolling element in contact with a user's body. The plurality of individually activatable therapy elements can be selectively activated based on an output of the sensor.

Abstract: Systems and processes for determining pressure settings for a percussive massage applicator are described. According to one embodiment, a method comprises obtaining an operational current measurement of the motor when the motor has a load. difference value is determined between the current measurement and the operational current measurement. The difference value is compared to two or more predetermined ranges of values that correspond to a pressure level of the percussive applicator. The pressure level may be provided as feedback to the user.

Abstract: A self-contained reciprocation mechanism is coupleable within an enclosure of a percussive massage device and is configured to receive an applicator head for stimulating a user's muscles. The self-contained reciprocation mechanism includes a spatial positioning bracket, a semi-cylindrical bracket, a piston, a motor, a crank, and a reciprocation linkage. The spatial positioning bracket is configured to receive the other interconnected components of the self-contained reciprocation mechanism and position said components relative to each other at close predetermined tolerances to assure that the interconnected components are properly positioned to provide consistent operating characteristics. The self-contained reciprocation mechanism is coupled within the enclosure using screws which extend through mounting tabs of the spatial positioning bracket.

Abstract: A percussive massage device includes a self-lubricating cylinder extending along a longitudinal axis. A motor shaft rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot offset from the central axis. A reciprocation linkage is coupled between the 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 annular gasket positioned between the cylinder and the applicator head removes lubricant from an outer surface of the piston to inhibit the lubricant from reaching the applicator head.

Abstract: A percussive massage device includes an enclosure having a cylindrical bore that extends along a longitudinal axis. A motor has a rotatable shaft that rotates about a central axis perpendicular to the longitudinal axis. A crank coupled to the shaft includes a pivot, which is offset from the central axis of the shaft. A reciprocation linkage has a first end coupled to the pivot of the crank. A piston has a first end coupled to a second end of the reciprocation linkage. The piston is constrained to move within a cylinder along the longitudinal axis of the cylindrical bore. An applicator head has a first end coupled to a second end of the piston and has a second end exposed outside the cylindrical bore for application to a person receiving treatment. A motor controller measures current applied to the motor and displays a pressure indicator responsive to the measured current.

Abstract: A therapeutic device for applying vibration, thermal and compressive therapy is disclosed. According to one embodiment, the device has a top layer and a bottom layer adapted to contact a body surface of a user. The device further includes a therapeutic element disposed between the top layer and the bottom layer, the therapeutic element including a vibration component, a thermal component, and a compression component, where, upon activation of the therapeutic element: (i) the vibration component applies a vibration force, (ii) the thermal component applies a thermal therapy, and (iii) the compression component applies a compressive force.

Abstract: 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.
