Computerized orthotic prescription system
A method for tuning an orthosis for the correct stiffness and/or shank angle includes via one or more computers, receiving patient information including forces experienced by a joint of a patient wearing an orthosis, wherein the orthosis has a degree of stiffness and a shank angle, via one or more computers, comparing the patient information to model information, wherein the model information includes the forces of a correctly functioning joint, and changing the degree of stiffness and/or the shank angle of the orthosis.
1. A method for tuning an orthosis, comprising:
via one or more computers, receiving patient information including moment forces experienced by a joint of a patient wearing an orthosis, wherein the orthosis has a degree of stiffness and/or shank angle; via one or more computers, comparing the patient information to model information, wherein the model information includes the moment forces of a correctly functioning joint; and changing the degree of stiffness and/or shank angle of the orthosis, wherein changing the degree of stiffness and/or shank angle includes a step selected from a group consisting of trimming a portion of the orthosis to decrease stiffness, and increasing or decreasing friction of a mechanical pivot linking two components of the orthosis.
2. The method of claim 1 , further comprising, via the one or more computers, providing a deviation between the patient information and the model information.
3. The method of claim 1 , further comprising, via the one or more computers, providing a recommendation on whether to increase or decrease stiffness and/or shank angle of the orthosis.
4. The method of claim 3 , wherein the recommendation is sent over a network.
5. The method of claim 4 , wherein the patient information is sent from a local computer over a network to a remote server, and the recommendation is sent from the remote server to the local computer.
6. The method of claim 1 , wherein the joint is an ankle.
7. The method of claim 1 , wherein the joint is a knee.
8. The method of claim 1 , wherein the joint is a hip.
9. The method of claim 1 , further comprising, via the one or more computers, receiving patient physical information that describes a distance from the joint to a reference point.
10. The method of claim 9 , wherein the joint is an ankle, and the reference point is located at the posterior of the heel along a horizontal line from the ankle.
11. The method of claim 1 , further comprising sending patient information over a network.
12. The method of claim 1 , further comprising increasing or decreasing the shank angle of the orthosis.
13. The method of claim 1 , wherein the patient information is compiled from information gathered during walking as a patient's foot contacts the ground.
14. The method of claim 1 , wherein the model information is corrected for the weight of the patient.
15. The method of claim 1 , wherein the model information is compiled from samples of correctly functioning joints.
16. The method of claim 1 , further comprising displaying a graph of the patient information.
17. The method of claim 1 , further comprising displaying a graph of the model information.
