Esteki-96-1 [Target]
Joint: MP-Joint of Index Finger
Direction: Flextion-Extension
Characteristic(s): Viscoelasticity

[Measurement Condition]
Subjects: 2 males and 1 female
Age Span: 25-45
Country: USA
Method: Estimation by quasi-static equilibration (type 1-3)

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

[Expression of the data]
A non-linear function of moment to the joint angle
Elasticity: an exponential function (unit:Ncm)

Viscosity: a non-linear function (unit:Ncm)



[Characteristics]
  • The viscous and elastic resistance are measured with the same system. Measuring the elastic/viscous resistance, the finger rotates slowly/quickly with constant velocity.
  • The hysteresis is descripted by above 2 viscous functions.
