Range of motion improvement device
An end range of motion improving device is disclosed including, first and second link members to independently rotate an upper leg and a lower leg of a patient, having a controller to selectively rotate the link members, and a networked computing system to facilitate communication between the controller and other networked devices.
1. An end range of motion improving device comprising:
a linkage, the linkage including:
a first link member;
a second link member supported on the first link member, the second link member configured for being secured to a lower leg of a patient and being rotatable about a second link member axis for rotating the lower leg of the patient about a knee axis of the patient through a lower leg range of motion, the second link member axis being displaceable into a selectable fixed position aligned with the knee axis and maintaining the fixed position during rotation of the second link member;
an actuator for rotating the second link member about the second link member axis; and
a controller controlling the actuator for selectively rotating the second member link member about the second link axis through the lower leg range of motion.
2. The end range of motion improving device according to claim 1 , wherein the first link member is configured for being secured to an upper leg of the patient and is rotatable about a first link member axis for rotating the upper leg of the patient about a hip axis of the patient through an upper leg range of motion.
3. The end range of motion improving device according to claim 2 , wherein the second link member includes a lower leg support to rotate the lower leg of the patient about the knee axis.
4. The end range of motion improving device according to claim 1 , wherein the second link member includes a lower leg support for supporting the lower leg on the second link member.
5. A method of providing end range of motion therapy, the method comprising:
providing the end range of motion improving device according to claim 1 ,
providing a user input to the controller for rotating the second link member;
providing a user input to the controller for indicating therapy parameters; and
rotating the lower leg according to the user input and the therapy parameters.
6. The method according to claim 5 , further comprising:
configuring the first link member to be secured to an upper leg of the patient and to be rotatable about a first link member axis for rotating the upper leg of the patient about a hip axis of the patient through an upper leg range of motion;
providing a user input to the controller for rotating the first link member; and
rotating the upper leg according to the user input and the therapy parameters.
7. An end range of motion improving device comprising:
a linkage, the linkage including:
a first link member;
a second link member mounted on the first link member, the second link member configured for being secured to a lower leg of a patient and being rotatable about a second link member axis for rotating the lower leg of the patient about a knee axis of the patient through a preset lower leg range of motion, the second link member axis being displaceable into a selectable fixed position aligned with the knee axis by an adjustment of the first link member, the fixed position being maintained during rotation of the second link member;
an actuator for rotating the second link member about the second link member axis; and
a controller controlling the actuator for selectively rotating the second link member about the second link member axis through the preset lower leg range of motion.
