Abstract
Joint measurement is necessary for studying joint laxity. Joint laxity in elbows is
a problem which normally comes with age. However, it can increase to critical
levels with rupture or damage to the ligaments of the elbow and affects the
stability and capabilities of the joint, interfering even with daily activities.
A new Stewart platform based elbow joint measurement was developed. The
study focused on flexion, extension, valgus and varus motions and all
experimental data were taken from a real experimental setup. The centre of
rotation and motion of the angles of the forearm were found by the kinematics of
the Stewart Platform Mechanism with a simmechanics based program algorithm.
The joint motions of two male subjects were measured and the results of these
measurements were compared with graphs. Comparisons demonstrate that the
Stewart platform based measurement device sufficiently measures all motions of
the elbow with six axes.
Keywords: joint laxity, Stewart platform, elbow kinematics.
