Derivation of the kinematic reference profile for two representative patients. BioTone data for: a) patient with normal flexor tone (MAS = 0), and b) patient with moderate tone (MAS = 1+). Displacement curves are shown in the top row. Gray construction lines illustrate the analytical approach to defining a time interval (T1-Tr) to represent the intended kinematic (reference) profile by the therapist. Within the interval T1-Tr an acceleration profile was constructed to represent a constant jerk curve (bottom row). Actual and reference kinematic profiles are indicated by bold and dashed lines, respectively. T2 represents the end of the motion.
