Musculoskeletal activity monitor
First Claim
Patent Images
1. A musculoskeletal monitoring system comprising:
- acceleration sensor means to be mounted on a subject for measuring vertical accelerations of the subject;
EKG sensor means to be mounted on the subject for generating EKG signals relating to the heart of the subject;
signal storage and processing means coupled to said sensor means for storing vertical acceleration signals from said acceleration sensor means for successive time periods each of a selected duration, and for storing said EKG signals from said EKG sensor means for said successive time periods, and for processing said acceleration signals to measure the step rate of the subject and to derive the foot ground force of the subject during each of said time periods and to determine whether the subject is in a walking mode or a running mode during each of said time periods, and for producing data relating to the working/running mode, time periods, step rate, Foot Ground Force and heart rate of the subject for each of said successive time periods.

Abstract
A musculoskeletal activity monitoring system for use in orthopedic studies in which data from various sensors mounted on a subject are used to monitor the EKG of the subject, as well as, vertical accelerations of the subject and posture of the subject, and in which signals from such sensors are stored and processed over measured time periods to provide desired musculoskeletal activity data.
