Table 2 Summary of results concerning the onset angle, the amplitude of initial flexion (F1Amp), the amplitude of initial extension (E1Amp), the relaxation index (RI), the extension relaxation index (ERI), the stiffness (KF1) and the viscosity (BF1) during the first flexion.

From: The pendulum test as a tool to evaluate passive knee stiffness and viscosity of patients with rheumatoid arthritis
