【 摘 要 】

References(21)We designed a new method ofmeasuring the length of the ulnar nerve and determining standard values for F-waveparameters of the ulnar nerve in clinically normal beagles. Nerve length must be preciselymeasured to determine F-wave latency and conduction velocity. The length of the forelimbhas served as the length of the ulnar nerve for F-wave assessments, but report indicatesthat F-wave latency is proportional to the length of the pathway traveled by nerveimpulses. Therefore, we measured the surface distance from a stimulus point to the spinousprocess of the first thoracic vertebra (nerve length 1) and the anterior horn of thescapula (nerve length 2) as landmarks through the olecranon and the shoulder bladeacromion. The correlation coefficients between the shortest F-wave latency and the lengthof nerves 1, 2 or the forelimb were 0.61, 0.7 and 0.58. Nerve length 2 generated thehighest value. Furthermore, the anterior horn of the scapula was easily palpated in anydog regardless of well-fed body. We concluded that nerve length 2 was optimal formeasuring the length of the ulnar nerve.
