Clinical Study on Acupoint Injection of Methylcobalamin for the Treatment of Cervical Spondylotic Radiculopathy

OBJECTIVE To observe the clinical efficacy of acupoint injection of Methylcobalamin in the treatment of cervical spondylotic radiculopathy (CSR).

METHODS A total of 90 patients with CSR in the outpatient department of Acupuncture-Moxibustion and Massage Department of Geriatric Hospital of Nanjing Medical University from April to October 2024 were selected and divided into a treatment group and a control group according to the random number table method, with 45 cases in each group. During the treatment, 1 case dropped out of the control group and 2 cases dropped out of the treatment group. Both groups received conventional electroacupuncture treatment, and the control group was given conventional intramuscular injection of Methylcobalamin (Mecobalamin injection), and the treatment group was given acupoint injection of Methylcobalamin. The treatment was given once every other day, for a total of 20 times. The changes of visual analogue score (VAS) of pain, cervical dysfunction index (NDI) score and electromyography F wave velocity were observed before and after treatment. The clinical efficacy of the two groups was compared after treatment.

RESULTS After treatment, the NDI and VAS scores of the two groups were significantly reduced (P < 0.01), and the NDI score of the treatment group was better than that of the control group (P < 0.01); the electromyography F wave velocity was significantly increased (P < 0.05), and the treatment group was better than the control group (P < 0.05, P < 0.01); the clinical efficacy of the treatment group was better than that of the control group (P < 0.01).

CONCLUSION Compared with conventional non-acupoint intramuscular injection, acupoint injection of Methylcobalamin can more effectively improve electromyography F wave velocity, and the clinical efficacy of CSR.
