Carpal Tunnel Release in Diabetic Patients
The aim of this study is to extend a previously reported 1 year follow-up on carpal tunnel release, in matched diabetic and non-diabetic patients,to compare outcomes 5 years after surgery.
Carpal Tunnel Syndrome
|Study Design:||Observational Model: Case Control
Time Perspective: Prospective
|Official Title:||Five Years Follow-up After Carpal Tunnel Release in Diabetic and Non-diabetic Patients|
- 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
- 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.

Diabetic patients operated for carpal tunnel syndrome
Non-diabetic patients operated for carpal tunnel syndrome
The Follow-up investigation includes:
- Clinical examination of sensory and motor function
- Generic and disease specific self-administered questionnaires
- Nerve conduction study
- Vibration threshold testing
