A comparative study of motor nerve conduction velocity of ulnar nerve between elbow extension and elbow flexion in patients with cubital tunnel syndrome
Objective
To compare the motor nerve conduction velocity (MNCV) of ulnar nerve between elbow joint natural extension and extreme flexion for 2 minutes in patients with cubital tunnel syndrome, and to explore the relationship between MNCV of ulnar nerve and elbow joint flexion and extension in patients with cubital tunnel syndrome.
Methods
Under two different conditions of elbow joint natural extension and extreme flexion for 2 minutes, 45 patients with cubital tunnel syndrome were examined by two methods: recording electrodes in the abductor digitorum minimi and the first dorsal interosseous muscle, and measuring the MNCV of ulnar nerve in the elbow tunnel segment. The MNCV of ulnar nerve was V1 at elbow extension and V2 at elbow flexion for 2 minutes when recording electrodes were in the abductor digitorum minimi; the MNCV of ulnar nerve was V3 at elbow extension and V4 at elbow flexion for 2 minutes when recording electrodes were in the first dorsal interosseous muscle. Matched-pair t-tests were performed for V1 and V2, V3 and V4, V1 and V3, V2 and V4, respectively.
Results
The MNCV of ulnar nerve in the elbow tunnel segment in the 45 patients were V1(29.47±8.37) m/s、V2(28.32±7.85) m/s、V3(27.91±9.62) m/s、V4(26.76±8.58) m/s, respectively. There was no significant difference in paired t test between V1 and V2, V3 and V4, V1 and V3, V2 and V4 (P>0.05).
Conclusion
There was no significant difference in MNCV of ulnar nerve in elbow segment between elbow joint extension and flexion in patients with cubital tunnel syndrome. There was no significant difference in the results of electromyogram between abductor digitorum minimi and first dorsal interosseous muscle. The results showed that elbow flexion or elbow extension had no significant effect on the results of electromyography in patients with cubital tunnel syndrome.
