TI  - Cooling modifies mixed median and ulnar palmar studies in carpal tunnel syndrome.
PG  - 779-82
AB  - Temperature is an important and common variable that modifies nerve conduction 
      study parameters in practice. Here we compare the effect of cooling on the mixed 
      palmar median to ulnar negative peak-latency difference (PMU) in electrodiagnosis 
      of carpal tunnel syndrome (CTS). Controls were 22 subjects (19 women, mean age 
      42.1 years, 44 hands). Patients were diagnosed with mild symptomatic CTS (25 
      women, mean age 46.6 years, 34 hands). PMU was obtained at the usual temperature, 
      >32 degrees C, and after wrist/hand cooling to <27 degrees C in ice water. After 
      cooling, there was a significantly greater increase in PMU and mixed ulnar palmar 
      latency in patients versus controls. We concluded that cooling significantly 
      modifies the PMU. We propose that the latencies of compressed nerve overreact to 
      cooling and that this response could be a useful tool for incipient CTS 
      electrodiagnosis. There was a significant latency overreaction of the ulnar nerve 
      to cooling in CTS patients. We hypothesize that subclinical ulnar nerve 
      compression is associated with CTS.
