Abstract

A brace compliance monitor is disclosed that includes a compliance sensor, a signal processor, and a display. Compliance data is displayed on the display to provide the patient or subject with immediate compliance information on whether they have been wearing the brace for the specified period and in the specified manner. The brace compliance monitor may also include a secondary sensor such as a tilt sensor, a pressure sensor, a force sensor, an acceleration sensor, or a velocity sensor. The secondary sensors may provide additional compliance data to the patient and health car provider.

Claims

1. A brace compliance monitor comprising:

a compliance sensor;

a display; and

a signal processing unit in communication with the compliance sensor and compliance display, wherein the signal processing unit receives and stores data from the compliance sensor as a function of time, compares the data received from the compliance sensor with a compliance protocol to produce compliance data, and displays compliance data on the compliance display.

2. The brace compliance monitor of claim 1 wherein the compliance sensor is selected from the group consisting of a temperature sensor, a capacitive sensor, and an optical sensor.

3. The brace compliance monitor of claim 1 wherein the display is either an LCD display or an LED display.

4. The brace compliance monitor of claim 1 further comprising a secondary sensor in communication with the signal processing unit, wherein the signal processor receives and stores data from the secondary sensor as a function of time.

5. The brace compliance monitor of claim 4 wherein the secondary sensor is one or more selected from the group consisting of a tilt sensor, a pressure sensor, a force sensor, an acceleration sensor, and a velocity sensor.

6. The brace compliance monitor of claim 4 wherein data from the secondary sensor is compared to the compliance protocol and displayed on the display.

7. The brace compliance monitor of claim 1 further comprising a brace wherein the compliance sensor and the signal processing unit are attached to the brace.

8. The brace compliance monitor of claim 7 wherein the brace is a scoliosis brace.

9. The brace compliance monitor of claim 7 wherein the display is attached to the brace.
