Area of Science:

  • Neuroscience
  • Medical Devices
  • Clinical Diagnostics

Background:

  • Carpal tunnel syndrome (CTS) is a common condition affecting the median nerve.
  • Accurate and efficient diagnostic methods are crucial for timely treatment.

Purpose of the Study:

  • To describe and evaluate a novel device for automatic sensory latency testing across the carpal tunnel.
  • To assess the diagnostic accuracy of the new device compared to conventional methods for CTS.

Main Methods:

  • The device utilizes a fixed bar with stimulating and recording electrodes based on the 14/7 orthodromic method.
  • Automatic pre-testing of electrode resistance and muscle relaxation ensures reliable stimulation.
  • A specialized algorithm analyzes latencies, with increased proximal/distal latency index indicating CTS.

Main Results:

  • The device was tested on 32 healthy hands and 258 hands with suspected CTS.
  • 94% agreement was found between the new device and routine CTS testing.
  • The device demonstrated potential in detecting CTS, even in cases with co-existing polyneuropathy, with a test time of approximately 1 minute per hand.

Conclusions:

  • The developed device for automatic sensory latency testing demonstrates highly promising results for CTS diagnosis.
  • The automated approach offers a rapid and potentially more accurate method for evaluating carpal tunnel syndrome.
