From: A portable system to measure knee extensor spasticity after spinal cord injury
Experimental setup. A Positioning of the leg IMU-based sensors on the thigh and shank using adhesive velcro straps and of the passive markers for the optical tracking system on the anatomical landmarks. B Example of knee kinematics during the pendulum test. The knee angle is depicted in black, while the knee angular velocity is in blue. The arrows indicate the measurement corresponding to the first swing angle (FSA)
