The relation between absolute muscle strength measures, gender and the estimated viscoelastic properties in patients. Plots depict: (A) muscle stiffness (k) and; (B) muscle viscosity (b). Both measures are plotted against the underlying muscle strength defined as the summed maximum flexor and extensor torques. Male patients (triangles were all stronger than female patients (circles)
