Electrodiagnostic examination of the tibial nerve in clinically normal ferrets.

Bianchi E, Callegari D, Ravera M, Dondi M - Vet Med Int (2010)

Bottom Line: The minimum latency of the F waves and the F ratio were, respectively, 8.49 +/- 0.65 ms and 1.92 +/- 0.17.Onset latency of CDP was 1.99 +/- 0.03 ms.These tests may help in diagnosing neuromuscular disorders and in better characterizing the hindlimb paresis reported in many ferrets with systemic illnesses.

ABSTRACT
Tibial nerves of 10 normal domestic ferrets (Mustela putorius furo) were evaluated by means of electrodiagnostic tests: motor nerve conduction studies (MNCSs), supramaximal repetitive nerve stimulation (SRNS), F waves, and cord dorsum potentials (CDPs). Values of conduction velocity, proximal and distal compound muscular action potentials, and amplitudes of MNCS were, respectively, 63.25 +/- 7.56 m/sec, 10.79 +/- 2.75 mV, and 13.02 +/- 3.41 mV. Mean decrements in amplitude and area of compound muscular action potentials of wave 9 with low frequency SRNS were 0.3 +/- 3.83% and 0.1 +/- 3.51%. The minimum latency of the F waves and the F ratio were, respectively, 8.49 +/- 0.65 ms and 1.92 +/- 0.17. Onset latency of CDP was 1.99 +/- 0.03 ms. These tests may help in diagnosing neuromuscular disorders and in better characterizing the hindlimb paresis reported in many ferrets with systemic illnesses.

Mentions: CDP consisted of a large negative peak followed by a long-latency positive deflection (Figure 5). CDP onset latency was 1.99 ± 0.03 ms, onset-to-peak latency difference was 1.85 ± 0.36 ms and peak amplitude was 4.92 ± 2.93 μV (Table 3).
