Abstract:
A shoulder arthrometer for measuring glenohumeral joint translation upon application of a force to an arm of a patient, comprising:a) an arm attachment assembly capable of being secured to the arm of a patient; b) a force measurement gauge operably engaged with said arm attachment assembly for measuring a force applied to the arm attachment assembly in anterior-posterior directions and the inferior direction; c) a translation measurement gauge assembly operably engaged with said arm attachment assembly, said translation measurement gauge assembly being capable of measuring anterior-posterior translations and inferior translations relative to the arm of a patient, said translation measurement gauge assembly including a girdle connecting element; and, d) a girdle assembly operably engageable with said girdle connecting element, said girdle assembly being capable of being secured to the torso of the patient to provide a fixed point of reference, wherein during application of either an anterior-posterior force or an inferior force to an arm of a patient, glenohumeral joint displacement is measured, the amount of force being registered by said force measurement gauge, while the amount of translation is registered via said translation measurement gauge assembly.
