Hayes-77-1 [Target]
Joint: Elbow
Direction: Flexion-Extension
Characteristic(s): Viscoelasticity

[Measurement Condition]
Subjects: 3 males
Age Span: 26-29
Country: Canada
Method: Estimation by dynamic equilibration (type 2-1)

[Definition]
Refer to the figure on the right side.

[Expression of the data]
Elasticity: Graph of a elastic moment to joint angle, function not shown
Viscosity: A quadratic function of the coefficient to joint angle (unit:Nms/deg)


[Characteristics]
  • The viscoelasticity is estimated from the oscillation of the forearm with the fixed upper arm.
  • The raw data of the elastic reistance to the joint angle about 3 persons exist.
  • The viscous coefficient function is defined about only 1 person. The patterns of damping oscillation about 3 persons are shown.
