The relation between UMN symptoms, muscle strength and the estimated reflexive properties of patients. Plots depict: A-B) force feedback gain (kf) and reflexive torque (Tref), respectively, stratified by the presence of upper motor neuron (UMN) symptoms in the cervical region; C-D) kf and Tref compared to the UMN score, grading severity in the examined arm, and; E-F) kf and Tref compared to wrist strength, defined by the summed maximum flexor and extensor torque
