RESUMO
Objective To compare the vibrating perception threshold (VPT) between normal subjects and subjects with cervical spondylosis of nerve root type, and to observe the clinical efficacy of acupoint injection at Quyuan (SI13) in releasing pain in cervical spondylosis of nerve root type.Method Sixty-three patients with cervical spondylosis of nerve root type were recruited and randomized into a treatment group of 35 cases and a control group of 28 cases. The treatment group received acupoint injection at Quyuan, and the control group received acupoint injection at Jiaji (EX-B2) points. The short-form McGill Pain Questionnaire (MPQ) was adopted. From the questionnaire, the Pain Rating Index (PRI), sensory (S), affective (A), and total (T) pain rating indexes, Visual Analogue Scale (VAS), and Present Pain Index (PPI) were used to comprehensively evaluate the pain improvement and to quantify the therapeutic efficacy, and the VPT was also considered. The Clinical Assessment Scale for Cervical Spondylosis (CASCS) by West China Rehabilitation Center was also used to analyze the result in the treatment group.Result After the intervention, the MPQ and VAS scores in the treatment group were significantly lower than those in the control group (P<0.05). The total effective rate of the treatment group was significantly higher than that of the control group (P<0.05). Meanwhile, the VPT was improved after the treatment.Conclusion Acupoint injection at Quyuan can produce a more significant efficacy than at Jiaji (EX-B2) in treating cervical spondylosis of nerve root type.
