Several devices have been developed for rapid motor or sensory median nerve conduction testing.
We evaluated the validity and reliability of the Neurosentinel (NS) and NervePace (NP) electroneurometer for sensory and motor testing, respectively, compared with formal electrodiagnostic studies (EDS), and examined their potential role in workplace screening for carpal tunnel syndrome (CTS).
Thirty-two working subjects without CTS were examined and tested with the NS, NP, and EDS, and retested one week later.
Subjects were selected who did not have CTS, other hand or nerve problems, or jobs with significant ergonomic risks, in order to decrease the likelihood of changes over time in median nerve function.
Mean correlations of NP and NS with EDS latencies ranged from r=0. 69 to r=0. 85, with somewhat better correlation for NS (sensory) than NP (motor).
Test-retest reliability was greatest for motor EDS (r=0.86 to 0. 91) and similar for sensory EDS, NS, and NP (r=0. 72 to 0. 79) ; mean results were very similar.
Based on the observed relationship between NS or NP and EDS results, confidence intervals were calculated to represent the range ofEDS results consistent with a single NS or NP measurement.
These intervals ranged from ± 0.3 milliseconds (ms) for MS to ± 0.6 mser for NP, with similar ranges for change over time in an individual. (...)
