Further study details as provided by Skane University Hospital:

Primary Outcome Measures:
  • Patient self-reported outcome questionnaire [ Time Frame: 5 years after carpal tunnel release ] [ Designated as safety issue: No ]
    Measured by 1). Boston Carpal Tunnel Questionnaire regarding carpal tunnel symptoms and disability. 2). Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) registering health-related quality of life. 3). Cold intolerance on a CISS score

Secondary Outcome Measures:
  • Nerve conduction study and vibrotactile sense [ Time Frame: 5 years after carpal tunnels release ] [ Designated as safety issue: No ]

    Change in Median nerve function by measuring Distal motor latency and antidromic sensory conduction velocity over the carpal tunnel segment.

    Evaluate development of peripheral neuropathy by measure of sural nerve sensory conduction velocity, sural nerve amplitude and peroneal nerve motor conduction velocity.

    Vibrotactile sense of the hand measured at 7 difference frequences from 5 - 500 Hz.

Enrollment: 66
Study Start Date: November 2010
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
