Postoperative improvement in the index finger center of pressure trajectory during precision grip in patients with degenerative cervical myelopathy.

ABSTRACT:

Objective

The aim of this study was to kinetically evaluate the changes in precision grip in patients with degenerative cervical myelopathy before and after decompressive surgery.

Methods

Twenty-nine patients with degenerative cervical myelopathy participated in the study. Participants performed a grip-and-lift task by pulp pinch using their thumb and index finger before and after surgery. We monitored individual finger grip force (GF) and center of pressure (COP) trajectory in total five seconds and during the first second while lifting and holding an object. Correlations between the pre-operative COP trajectory and other hand clinical outcomes were analyzed. A multiple regression analysis was used to identify the predictive value of the pre-operative COP trajectory to the
