This study proposed a prototype of handy instrument for quantitative assessment of the patellar tendon reflex (PTR) responses in clinical practice. Focusing on kinematic features of PTR, an integrated limb-mounted equipment was developed utilizing a multi-axis inertial sensor, data logger, and miniature tap force sensor. To identify characteristics of PTR, relationships between tendon tap force and kicking movement of lower leg were investigated. Additionally, a simple rigid body physical model was introduced to estimate knee extension torque as a consequence of the stretch reflex. Frequency domain system identification was then applied to describe dynamic responses of the PTR. Usability and consistency of the handy equipment was examined in the experiment with a healthy adult subject. The results suggested that the proposed handy instruments consistently quantified features of PTR, which was feasibly characterized by a few simple mechanical parameters.
