Effectiveness of acupuncture in the management of cervical spondylosis: a meta-analysis.

Cervical spondylosis is the most common type of spinal pathology which is more common in middle-aged or senile populations with a high potential to affect physical and mental health. This study evaluates the effectiveness of acupuncture in the management of cervical spondylosis. After a detailed literature search in electronic databases, the required data were acquired from selected research articles and meta-analyses were performed to obtain the percent cure, failure and total effectiveness rates under random effects model. Meta-regression was performed to identify the factors affecting the efficacy. Twenty-seven studies were selected for data acquisition (2,853 patients; average age 46.2±9.5; 51.7±12.5% males). Acupuncture alone had 33.41% (25.50, 41.24) cure rate but in combination with other therapies it rose to 53.36% (41.9, 64.8). Similarly, total effectiveness rate was 87.01% (83.40, 90.62) with acupuncture alone and 93.62% (89.85, 97.38) with acupuncture in combination with other therapies. Age was inversely associated with the percent cure rate and the number of combination therapies with acupuncture was positively associated with the cure rate. In conclusion, acupuncture therapy alone can provide cure and total effectiveness rates of 33% and 87%, respectively, but acupuncture with additional therapies can improve the cure and total effectiveness rates to 53% and 94%, respectively. Age inversely affects efficacy and the number of additional therapies improves the efficacy.
