Neck and back muscle chains hypomobility in women with migraine.

Objective: To compare the mobility of neck and back flexor and extensor muscle chains in women with migraine, chronic migraine and headache-free.

Methods: This is a cross-sectional study. The muscle chain test was performed based on the theoretical assumptions of the Busquet method, in women with migraine (MG, n = 24), chronic migraine (CMG, n = 36) and headache-free (CG, n = 27). The evaluation of neck and back mobility was performed by an examiner expert in the Busquet method with the aid of cervical range of motion (CROM®) device (neck muscles) and the Tiltmeter® application (back muscles).

Results: Compared to woman headache-free, women with migraine (MD = -12° [CI95% = -19°, -5°] and chronic migraine (MD = -15° [CI95% = -21°, -8°] present reduced mobility in the neck extensor muscle chain. Also, in the back extensor muscle chain, migraine vs headache-free (MD = -9° [CI95% = -15°, -2°]) and chronic migraine vs headache-free (MD = -10° [CI95% = -16°, -4°]) and in the back flexor muscle chain, migraine vs headache-free (MD = -6° [CI95% = -10°, -0.1°]) and chronic migraine vs headache-free (MD = -7 [CI95% = -11°, -2°]), with an effect sizes varying between 1.19 e 2.38. No difference was found between groups for neck flexor muscle chain.

Conclusion: Women with migraine and chronic migraine have hypomobility of the neck and back extensor muscle chains, and of the back flexor chain.
