Abstract
An embodiment of the invention includes (a) modeling a first internal force applied to a model of a user's joint based on a first external force externally applied to the joint at a first position; (b) modeling a second internal force applied to the model based on a second external force externally applied to the joint at a second position unequal to the first position; (c) comparing the first and second modeled internal forces; and (d) stimulating the user based on the comparison. Other embodiments are described herein.
Claims1
A system comprising:
- at least one memory;
- at least one electrode;
- at least one sensor comprising at least one member selected from the group comprising:
- at least one electrode, at least one accelerometer, and at least one positional angular sensor;
- at least one controller, coupled to the at least one memory, to perform steps comprising:
- (a)(i) measure a first movement or position of a limb attached to a user's joint via the at least one sensor;
- (a)(ii) measure a second movement or position of the limb attached to the joint via the at least one sensor;
- (a)(iii) condition the measurement of the first movement or position of the limb via at least one signal conditioner, the at least one signal conditioner including a frequency filter and an analog-to-digital (A/D) converter;
- (a)(iv) condition the measurement of the second movement or position of the limb via the at least one signal conditioner;
- (b)(i) model a first internal force applied to the joint based on the conditioned measurement of the first movement or position of the limb attached to the joint at a first point in time;
- (b)(ii) model a second internal force applied to the joint based on the conditioned measurement of the second movement or position of the limb attached to the joint at a second point in time;
- (c)(1) compare the first and the second modeled internal forces;
- and
- (c)(2) stimulate muscle of the user, via the at least one electrode, based on the comparison.
