手関節 joint laxity の測定システム評価

抄録

The definition of the joint laxity is ambiguous. Practically, the joint laxity is evaluated by the Range of Motion (R.O.M.) and the feeling of stiffness during passive joint motion. But it is not clearly objective but rather complicated. For this reason, we attempted to objectively evaluate the joint laxity of wrist joints by originally developed apparatus. In this study, the wrist joints of five volunteers were examined both clinically by manual and objective by apparatus, and reported the validity and reproducibility by this measurement system.
