Method and apparatus for monitoring of daily activity in terms of ground reaction forces

摘要: A device to record and analyze habitual daily activity in terms of the history gait-related musculoskeletal loading is disclosed. The consists a pressure-sensing insole—placed into shoe or embedded sole—which detects contact foot with ground. sensor coupled portable battery-powered digital data logger clipped worn around ankle waist. During course normal activity, system maintains time-of-occurrence all non-spurious foot-down lift-off events. Off line, these are filtered converted foot-ground times, from which measures cumulative loading, average walking- running-specific gait speed, total time spent walking running, number steps running steps, energy expenditure estimated empirical regressions various parameters reciprocal. Data available as values averages by menu selection. provided this useful for assessment cardiovascular health risk factors associated patterns activity.
