Patent number: 11957481Abstract: Disclosed are a joint manipulation device and system for increasing the range of motion of a joint of a user, and monitoring the compliance of the user's operation of the joint manipulation device to standards or guidelines set by a monitoring entity. Certain sensors associated with the joint manipulation device may cause an indicator to transmit an alert to the user based on whether or not the device is sufficiently engaged with a limb or joint of the user to be considered in compliance. Additionally, progress data associated with the range of motion of the user's joint may be obtained by a sensor assembly and transmitted to one or more systems associated with the device system. Progress data obtained during a period of non-compliant use of the device may be excluded from the transmitted data, thereby generating a set of compliant progress data for accurate analysis of device effectiveness.Type: GrantFiled: February 21, 2020Date of Patent: April 16, 2024Assignee: ERMI LLCInventors: Shaun Kevin Stinton, Edward Dittmar, Thomas P.

Publication number: 20240065917Abstract: A device for manipulating a user's hand a wrist portion and forearm portion, each having proximal and distal ends. A pivoting connection is operatively coupled with the proximal end of the wrist portion and distal end of the forearm portions such that the wrist portion is pivotally coupled to the forearm portion. The device has a first actuator operatively coupled to the wrist portion and a second actuator operatively coupled to the pivoting connection. The first actuator is configured to apply a rotational force to a hand support coupled to the wrist portion, thereby producing either supination or pronation of a user's wrist. The second actuator is configured to apply a rotational force to the pivoting connection, thereby producing either flexion, extension, abduction, or adduction of a user's wrist, depending upon whether the user's hand is palm-side down or in a thumb's up position.Type: ApplicationFiled: August 30, 2023Publication date: February 29, 2024Inventors: Shaun Kevin Stinton, Thomas P.
