The efficiency and safety of manual therapy for cervicogenic cephalic syndrome (CCS): A systematic review and meta-analysis.

ABSTRACT

BACKGROUND: Manual therapy is a common technique for the treatment of (CCS) cervicogenic cephalic syndrome, but the efficiency is various. The aim of the study is to evaluate the evidence pertaining to the efficiency and safety of using manual therapy to treat patients with CCS. METHODS: We searched the electronic databases including PubMed, ScienceDirect, and the Cochrane Library. Only randomized controlled trials (RCTs) were enrolled in this systematic review and cumulative meta-analysis. RESULTS: A total of 8 RCTs with 395 patients were included for meta-analysis. Patients who underwent manual therapy showed lower scores of visual analog scale (VAS) (weighted mean difference) WMD = 1.7, 95% confidence interval CI = 0.74-2.65, P = .0005); dizziness handicap inventory (DHI) (WMD = 0.66, 95%CI = 0.31-1, P = .0002); and neck disability index (NDI) (WMD = 0.59, 95%CI = 0.23-0.96, P = .002) and better rotation range of motion (ROM) of the cervical spine (WMD = -6.54, 95%CI = -7.60 to -5.48, P < .0001). However, these patients did not show much benefit from manual therapy with respect to the frequency of CCS episodes and head repositioning accuracy (HRA). No serious adverse effects were reported in our included studies lasting longer than 24 hours. CONCLUSIONS: Manual therapy offers an effective and safe approach to treat CCS with lower VAS, DHI, and NDI scores and better cervical spinal movement. Further high-quality RCTs are required to provide more conclusive evidence. SYSTEMATIC REVIEW REGISTRATION NUMBER PROSPERO172740.
