Abstract

A brace includes a closed loop feedback system that provides electrical muscle stimulation (EMS) to a joint of a human patient in response to feedback from the joint and surrounding muscles. In one aspect, a brace for treating a human joint of a patient is provided. The brace includes one or more sensors in physical contact with the skin of the patient and configured to obtain a galvanic reading of resistance of the skin. The brace also includes brace control electronics in communication with the sensor(s) to form a closed loop system via a combination of bracing the joint and electrical muscle stimulation (EMS). The brace control electronics is configured to receive the galvanic reading of the resistance of the skin of the patient and is further configured to instruct the sensor to apply a current/voltage/power onto the skin based on the galvanic reading.

Claims

1. A system comprising:

a sensor in physical contact with skin of a patient and configured to obtain a galvanic reading of resistance of the skin;

control electronics in communication with the sensor to form a closed loop system via electrical muscle stimulation (EMS), the control electronics configured to receive the galvanic reading of the resistance of the skin of the patient and further configured to instruct the sensor to apply a current or voltage onto the skin based on the galvanic reading;

a support element for a body part or joint of the patient,

wherein the sensor comprises a plurality of sensors each configured to be in physical contact with different portions of skin of the patient and each configured to obtain a galvanic reading of the resistance of the corresponding portion of skin, and wherein the plurality of sensors further comprise a first plurality of sensors in physical contact with a first muscle group and a second plurality of sensors in physical contact with an antagonistic muscle group to the first muscle group, the first plurality stimulating the first muscle group and the second plurality stimulating the antagonistic muscle group to result in co-coupled contraction.

2. The system of claim 1, wherein the galvanic reading of the resistance of the portions of the skin further comprises a galvanic reading across two sensors when skin forms a circuit between the two sensors.

3. The system of claim 1, wherein the sensor is configured to obtain the galvanic reading of resistance of the skin further comprises the sensor being configured to obtain the galvanic reading of the resistance of sweat on the skin.

4. The system of claim 1, wherein the control electronics is further configured to provide the EMS via a program selected from a plurality of programs.

5. The system of claim 4, wherein the control electronics further comprise a receiver configured to receive a selection of the program.

6. The system of claim 1, wherein the control electronics and the sensor are components of a brace.

7. The system of claim 1, wherein the sensor is in physical contact with the skin of the patient without use of a gel or a sticky adhesive.

8. The system of claim 7, wherein the control electronics further comprise a communication module for receiving a program from a remote computing device for execution by the control electronics.

9. The system of claim 1, further comprising an authentication button that, when pressed, indicates that the patient acquiesces to a program being executed by the control electronics.

10. The system of claim 1, wherein the control electronics further comprises a tactile feedback provider configured to provide tactile feedback to the patient during a set time or event.

11. A method comprising:

providing a system for treating a human joint or body part of a patient, the system comprising;

a sensor for physical contact with skin of the patient and configured to obtain a galvanic reading of resistance of the skin;

control electronics in communication with the sensor to form a closed loop system via electrical muscle stimulation (EMS), the control electronics configured to receive the galvanic reading of the resistance of the skin of the patient and further configured to instruct the sensor to apply a current or voltage onto the skin based on the galvanic reading;
