First Claim
1. A method of acquiring biomechanical position data for use in postural analysis, the method comprising the steps of:
- a) selecting a plurality of marker positions referenced with respect to an anatomy of a patient by one of;
skin surface features having minimal variability from one patient to the next; and
skeletal features palpable from a skin surface of the patient;
b) attaching a scanable marker on the patient at each of the marker positions, the step of attaching including palpating the patient to define at least some of the marker positions;
c) instructing the patient to stand relaxed and in normal posture; and
d) scanning the markers attached to the patient to obtain position data for each of the marker positions.

Abstract
The present invention relates to a method of acquiring biomechanical position data for use in postural analysis, where a plurality of scanable markers are attached on the patient at marker positions, the patient is instructed to stand in normal posture, and the markers attached to the patient are scanned to obtain position data for each of them. The present invention also relates to a method for calculating postural deviation values in a patient where an angle of deviation value and distance of deviation value with respect to the plumb line position value are calculated using the biomechanical position data. The present invention further relates to a method of providing posture health care using a distributed system.

10. A method for calculating postural deviation values in a patient comprising the steps of:
-
a) obtaining position data identifying a position in space of body segments of the patient while standing relaxed and in normal posture, the body segments comprising head-shoulders, shoulders-pelvis, pelvis-hips, hips-knees and knees-ankles;
b) obtaining weight data of the patient;
c) calculating vertical and horizontal plumb lines using the position data;
d) calculating for at least some of the body segments an angle of deviation value and distance of deviation value with respect to plumb lines position value using the position data. - View Dependent Claims (11, 12, 13)

14. A method of selecting exercises for improving tonicity and correcting posture in a patient, the method comprising the steps of:
-
a) obtaining biomechanical position data of the patient while standing relaxed and in normal posture, the position data being indicative of postural problems requiring correction;
b) ranking the postural problems by severity and priority;
c) correlating the position data with exercises for strengthing or stretching specific muscles or muscle groups to obtain ranking data for the exercises;
d) compiling an exercise program for the patient based on the ranking data. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
a) calculating a center of mass plumb line position value using the position data and weight data;
b) calculating for at least some of the body segments an angle of deviation value and distance of deviation value with respect to the plumb line position value using the position data;
c) comparing the deviation values to normal values for the at least some of the body segments to obtain deviation priority values;
d) ranking the deviation priority values according to an order of severity or importance; and
e) determining the ranking data based on an association of the exercises with body segment deviations in accordance with the order of severity or importance.

-
19. The method as claimed in claim 18, wherein the step of ranking the deviation priority values according to an order of severity or importance comprises manually selecting deviations to be corrected by the exercise program, the order of severity or importance reflecting those deviations manually selected.
-
20. The method as claimed in claim 19, wherein the exercises are grouped in sets of exercises each attempting to correct a specific postural deviation, and the exercise program comprising a series of the sets of exercises.
-
21. The method as claimed in claim 20, wherein the exercise program is limited to a maximum number of exercises, the step of manually selecting deviations is automatically restricted when a maximum number of exercises corresponding to the selected deviations exceeds the maximum number for the exercise program.
-
22. The method as claimed in claim 14, wherein the step of compiling comprises repeating ones of the exercises corresponding to most severe postural problems regularly throughout the exercise program and including ones of the exercises corresponding to less severe postural problems for only part of the program.
-
23. The method as claimed in claim 22, wherein the step of compiling comprises including ones of the exercises corresponding to moderately severe postural problems more intensively for only part of the exercise program.
-
24. The method as claimed in claim 18, wherein the step of compiling comprises repeating ones of the exercises corresponding to most severe postural problems regularly throughout the exercise program and including ones of the exercises corresponding to less severe postural problems for only part of the program.
