Influence of cervical traction and manipulation on hemorheology of cervical vertigo patients

Abstract

Objective To observe the influence of cervical traction and manipulation on hemorheology of cervical vertigo patients.Methods 59 patients in outpatients of our hospital from January 2012 to August 2013 were recruited and divided into a control group（29 patients）and a treatment group（30 patients）randomly. The control group was treated with flunarizine, and the treatment group was additionally treated with cervical traction and manipulation on the basis of the control group. After 4 therapeutic causes, evaluation of cervical vertigo symptoms and functions（ESOV）were performed and hemorheological changes were observed in both groups.Results① ESOV comparison： ESOV sores in both groupswere obviously improved after the treatment than the same group before the treatment（t=11.028, 5.825,all P〈0.01）the treatment group were significantly lower than that in the control group after treatment（t=3.6057,P〈0.01）.② hemorheology changes comparison： whole blood viscosity（high-, medium- , low shear）, whole blood reduction viscosity, erythrocyte aggregation index, hematocrit in the treatment group were improved obviously after the treatment than before（t=3.356, 13.245, 3.650, 7.443, 9.912, 3.113,P〈0.05 orP〈0.01）. The whole blood viscosity（high-, medium-shea）, blood reduction viscosity, erythrocyte aggregation index in the control group were obviously improved than the before（t=2.144, 4.216, 3.287, 3.039, 6.442,P〈0.05 orP〈0.01）. The difference between the two groups were also obvious after the treatment（P〈0.05 orP〈0.01）.Conclusions Cervical traction and manipulation combined with flunarizine can elevate ESOV score, improve hemorheology and therapeutic effect in patients with cervical vertigo.
