[Effects of acupuncture at Dazhui (GV 14) on brain stem auditory evoked potentials in the patient with cervical spondylosis of vertebral artery type].

OBJECTIVE

To study on the mechanism of Dazhui (GV 14) in treatment of cervical spondylosis of vertebral artery type, and to explore the feasibility of regarding hrain stem auditory evoked potential (BAEP) as the objective criterion for assessment of the therapeutic effect.

METHODS

Fifty-two cases of cervical spondylosis of vertebral artery type were treated with acupuncture at Dazhui (GV 14), their therapeutic effect and changes of BAEP before and after treatment were investigated.

RESULTS

Seventeen cases were cured, 26 cases improved and 9 cases were ineffective, with an effective rate of 82.7%. In BAEP, V PL, I-III IPL, III-V IPL had significant changes after treatment (P < 0.05), with a significant difference between the clinically effective group (cured and improved) as compared with the ineffective group (P < 0.05, P < 0.01).

CONCLUSION

Acupuncture at Dazhui (GV 14) improves blood supply of the vertebrabssilar artery, eliminates or alleviates clinical symptoms of cervical spondylosis of vertebral artery type. BAEP can be used as the criterion for assessment of the therapeutic effect.
