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. Branch, T. Christopher Madden

Patent number: 11666501Abstract: Devices manipulate a hand of a user to provide pronation or supination assistance. Embodiments include an anchor; a hand engagement member operatively attached to the anchor and configured to receive and engage the hand of the user; a force applicator having a member portion and an anchor portion opposite the member portion, the force applicator attached to the hand engagement member proximate its member portion and attached to the anchor proximate its anchor portion; and a force application mechanism attached to the anchor and configured to cause a force to be applied to the force applicator causing the hand engagement member to manipulate the hand of the user to provide pronation or supination assistance. In some embodiments, the force application mechanism includes a non-incremental rotary mechanism. In some embodiments, a flexible tethering member attaches the anchor to the hand engagement member.Type: GrantFiled: March 19, 2019Date of Patent: June 6, 2023Assignee: Ermi LLCInventors: Thomas P.
