The main objective was to investigate if the cumulative load of the lower limbs, defined as the product of external load and step rate, could be predicted using spatiotemporal variables gathered with a commercially available wearable device in running. Therefore, thirty-nine runners performed two running tests at 10 and 12 km/h, respectively. Spatiotemporal variables (step rate, ground contact time and vertical oscillation) were collected using a commercially available wearable device. Kinetic variables, measured with gold standard equipment (motion capture system and instrumented treadmill) and used for the calculation of a set of variables representing cumulative load, were peak vertical ground reaction force (peak vGRF), vertical instantaneous loading rate (VILR), vertical impulse, braking impulse, as well as peak extension moments and angular impulses of the ankle, knee and hip joints...

The estimation of the human ankle's mechanical impedance is an important tool for modeling human balance. This work presents the implementation of a parameter-estimation approach based on the State-Augmented Extended Kalman Filter (AEKF) to infer the human ankle's mechanical impedance during quiet standing. However, the AEKF Filter is sensitive to the initialization of the noise covariance matrices. In order to avoid a time consuming trial-and-error method and to obtain a better estimation performance, an algorithm based on Genetic Algorithms (GA) is proposed for tuning the measurement noise Rk and process noise covariances Q of the Extended Kalman filter (EKF)...

Background: The lymph vessels from the dorsum and the medial ankle ascending to the medial side of the thigh toward the inguinal lymph nodes can be observed by the linear flow using indocyanine green near-infrared lymphography (ICGL). Although anatomical studies have shown the widespread existence of lymphatic vessels throughout the body, ICGL shows little linear flow. We herein report our findings of the course of lymph vessels in healthy lower limbs. Methods: The unaffected lower limbs of 14 patients who underwent lymphaticovenular anastomosis were evaluated for this study...
