... the instrumented rat stepper can provide a sensitive and reliable measure of hindlimb locomotor strength and control of flexor and extensor muscle activity in neurologically impaired animals. Additionally, these measures may be useful as a means to quantify training intensity or dose-related functional outcomes...

... structure are known to exhibit stress-strain hysteresis: smooth muscle within the alveolar entrance rings, and surfactant at the air-tissue interface. We hypothesize that the geometric hysteresis of the alveolar duct is largely determined by the interaction of the amount of smooth muscle and connective...

... driven by a constant offset throughout the gait cycle. We observed that different methods for data analysis can produce largely different kinematic results, which could lead to the misclassification of normal or pathological gait and then may be compounded when estimating joint moments or muscle...

Investigations into the passive viscoelasticity of muscle have primarily focused on characterizing...

.... It is important to re-establish the tendon-to-bone insertion site because it provides joint stability and enables force transmission from muscle to tendon and subsequent loading of the tendon. Without loading, tendon mechanical properties deteriorate. Future studies by our laboratory will investigate potential...
