Parkinsonian Rigidity Shows Variable Properties Depending on the Elbow Joint Angle
Figure 2
Methods of analysis of properties of elbow joint movements for each of the distal and proximal segments with the joint angle of “cutoff point” as their boundary. (a) One regression line was fitted to the data of the 10°–110° portion of the degree-torque characteristics curve obtained during extension of the elbow joint of a normal healthy subject. (b) Two regression lines were fitted to the data of the same subject. The extension of the elbow joint was divided into the proximal phase and distal phase at the angle of the elbow joint of “cutoff point.”
