“…Although many clinical and biomechanical studies address CTS (Bland, 2000;Liu et al, 2000 MacDermid andWessel, 2004;Nobuta et al, 2005), the electrophysiological properties of the APB muscle are still not well understood. Reliable information about the physiological fatigue behavior of the APB muscle could be valuable to recognize changes in a pathologically altered muscle, as for instance in the case of CTS.…”

“…The ESCTS patients were included if they had no previous surgery for CTS and a grade 6 CTS according to Bland's neurophysiological scale [12]. This means that the sensory and motor potentials are unrecordable and that the surface motor potential from muscle abductor pollicis brevis was < 0.2 mV amplitude.…”

“…Grade 4: severe CTS detected by delayed median motor DL but less than 6.5 ms with absent median SNAP. Grade 5: very severe CTS detected by delayed median motor DL more than 6.5 ms. Grade 6: extremely severe CTS detected by delayed median motor DL with decreased median CMAP amplitude (surface CMAP amplitude is less than 0.2 mV) [18]. Statistical analysis of data was done by using the Statistical Package of Social Science (SPSS version 17) software [19].…”

Aim of the work: This study proposed to assess the role of the median versus ulnar medial thenar motor (MTM) recording in supporting the diagnosis of carpal tunnel syndrome (CTS).Patients and methods: The present study included 130 hands (70 CTS and 60 controls). Clinical examination was done for all patients. The following tests were done (using surface electrodes recording) for patients and control: (1) sensory nerve conduction studies: median nerve, ulnar nerve and median versus ulnar digit four sensory study; (2) motor nerve conduction studies: median nerve, ulnar nerve, median (second lumbrical) versus ulnar (interosseous) (2-LINT) motor study and median versus ulnar (MTM) study.Results:The tests with higher sensitivity in diagnosing CTS were median versus ulnar (2-LINT) motor latency difference (87.1%), median versus ulnar (MTM) motor latency difference (80%) and median versus ulnar digit four sensory latency difference (91.4%). There was no statistically significant difference between median versus ulnar (MTM) motor latency difference with both median versus ulnar (2-LINT) motor latency difference and median versus ulnar digit four sensory latency difference (P > 0.05) as regards the confirmation of CTS.Conclusions: Median versus ulnar (MTM) motor latency difference has high sensitivity and specificity for the diagnosis of CTS as for both median versus ulnar (2-LINT) motor latency difference and median versus ulnar digit four sensory latency difference. It can be considered a useful neurophysiological test to be used in combination with other median versus ulnar comparative tests for confirming the diagnosis of CTS beside other well known electrophysiological tests.
