The Comorbidity Between the Trigger Digit and Carpal Tunnel Syndrome Clinical Trial
Official title:
Investigation of the Relation Between Trigger Digit and Carpal Tunnel Syndrome
The purpose of this study is to comprehend the association between the trigger digit and
carpal tunnel syndrome based on the quantification of the tendon and nerve characteristics.
It includes three parts.
The first part is an observational study. The aim of the first part is to attempts to measure
the gliding and morphological characteristics of the flexor tendons and median nerve in the
longitudinal or cross-sectional directions via the ultrasonographical images incorporating
with the motion capture experiment of the wrist and fingers. The gliding and morphological
features of the tendons and nerve will be compared under different postures or movement
patterns of the wrist and hand.
The second part is an interventional study. The aim of the first part is to establishes a
novel hybrid rehabilitation protocol which combines the tendon gliding exercise with nerve
mobilization to treat either the trigger digit or the carpal tunnel syndrome. A randomized
controlled trial to investigate the short-term treatment effect and the follow-up examination
will be carried out as well.
The third part is an observational study. The aim of the first part is to investigate the
effects of carpal tunnel release on the hand performances from functional perspectives. In
addition, a novel wrist orthosis will be developed to eliminate the bowstringing effect of
the flexor tendons after carpal tunnel release.
