N2 - This study aims to estimate the stiffness of the vastus lateralis muscle during quiet standing using a system identification technique.Six healthy males (age 22) participated in the experiment.The electrical timulation, a monopolar rectangular pulse of 500 µs and approximately 30 mA, was applied to the vastus lateralis muscle.The electrically induced reaction force was measured with a force plate.The transfer function from the electrical stimulation to the induced reaction force was identified as a fifth-order model.The model consists of two second-order models and one first-order model.One of the second-order models provided muscle stiffness of 630 to 1119 N/m.
