Subjects with episodic migraine exhibited widespread hypersensitivity in cranio-cervical region. Our objectives were to explore the potential factors associated with the presence of neck pain for EM, and whether there were differences in pericranial muscle tenderness between EM with and without neck pain.Patients and methods: Fifty EM with neck pain (34.76±8.04) and 50 age- and sex-matched EM without neck pain (34.26±9.39) were enrolled. The characteristics of headaches and some lifestyle factors were assessed in two groups. The migraine disability score and neck disability index were also recorded. During migraine-free period, cranio-cervical muscle tenderness scores and mechanical pain threshold were assessed for all patients.Results: There were no significant differences in pain intensity (p=0.44), migraine disability (p=0.71), duration (p=0.44) or frequency (p=0.85) of headache between EM with and without neck pain. The lifestyle factors including smoking, alcohol, coffee, body mass index≧23kg/m2, poor sleeping (<8 h/day) and time spent on TV and computers (>2 h/day) were not associated with the presence of neck pain in this study. Compared with EM without neck pain, those with neck pain had higher neck tenderness (p<0.01) and higher cephalic tenderness scores (p<0.01). Neck Disability Index scores were positively correlated with neck and total muscle tenderness scores.Conclusion: There was a significant difference in cranio-cervical muscle tenderness scores between EM with and without neck pain. For EM, the factors studied in the current research seemed not associated with the onset of neck pain, and further studies including other factors are needed.Keywords: episodic migraine, neck pain, muscle tenderness, neck disability
