Abstract

A system and method for addressing patient health through monitoring patient movement that includes, during a treatment stage, collecting kinematic data from at least one inertial measurement unit of an activity monitoring system; generating a set of biomechanical signals from the kinematic data wherein the set of biomechanical signals characterize at least one biomechanical property; updating a mobility quality score of the subject based on the set of biomechanical signals; and delivering a health assessment.

Claims

1. A method for addressing patient health through monitoring patient movement comprising:

in association with at least one treatment stage, collecting kinematic data from at least one inertial measurement unit of an activity monitoring system, wherein the activity monitoring system is coupled to a subject;

generating a set of biomechanical signals from the kinematic data wherein the set of biomechanical signals characterize at least one biomechanical property;

updating a mobility quality score of the subject based on the set of biomechanical signals; and

delivering a health assessment.

2. The method of claim 1, further comprising tracking administration of a treatment;

and wherein the health assessment is an analysis of the treatment based in part on the motion quality in comparison to the administration of the treatment.

3. The method of claim 2, wherein the treatment is a set of physical therapy sessions, and wherein the assessment indicates mobility quality relative to tracked physical therapy sessions.

4. The method of claim 2, wherein the treatment is a set of physical therapy sessions, and wherein the health assessment includes a physical therapy treatment recommendation.

5. The method of claim 2, wherein the treatment is administration of a drug, and wherein the health assessment includes a drug treatment recommendation with recommended drug dosage and timing.

6. The method of claim 5, wherein the drug is a pain medicine.

7. The method of claim 2, wherein the treatment is usage of a medical device.

8. The method of claim 1, wherein collecting the kinematic data and generating the set of biomechanical signals are performed during the recovery stage of a treatment;

and wherein the assessment is a recovery report.

9. The method of claim 1, wherein the treatment stage is a treatment analysis stage, and wherein the assessment includes a metric for predicted treatment impact.

10. The method of claim 1, wherein the treatment stage is a post-surgery analysis stage.

11. The method of claim 10, wherein delivering the health assessment comprises comparing current motion quality score from a current post-surgery stage to a motion quality score from a pre-surgery stage.

12. The method of claim 1, wherein the treatment stage is a diagnosis stage;

further comprising directing actions by a patient;

wherein biomechanical signals are generated during each directed action, wherein the health assessment is a motion disorder diagnosis report.

13. The method of claim 1, wherein updating the mobility quality score comprises detecting an event risk scenario through the biomechanical signals;
