Differences in the electrical activity and the clinical performance of superficial neck flexors and extensors during the CCFT in women with migraine

IntroductionMusculoskeletal disorders in the cervical spine have been increasingly investigated and observed patients with migraine. One of them is a poorer muscle performance as assessed by cranio-cervical flexion test (CCFT). In addition, migraine alterations recruitment motor units surface electromyography during CCFT. ObjectiveThe aim was to verify if there are differences electrical activity clinical superficial neck flexors extensors CCFT women considering presence or absence concomitant pain symptoms. MethodsA total 100 were assessed: 25 without pain, mechanical pain-free control. Clinical demographic data collected, The performed all groups. deep pressure unit biofeedback placed posterior region initially inflated 20 mmHg composed 5 stages, increase 2 at each stage, reaching 30 mmHg, keeping for 10 seconds resorting compensation. Electromyography collected TrignoTM Wireless System wireless sensors. sensors firmly attached bilaterally on: sternocleidomastoid (SCM); splenius capitis, anterior scalene upper trapezius. Electromyographic evaluated normalized average root mean square (RMS) calculated reference voluntary contraction expressed percentage. Groups comparisons non-parametric tests adopting level significance 0.05. To analyze between-groups on proportion targeted stages reached participant within CCFT, chi-square (X2) calculated, submitted post-hoc test. (To see complete abstract, please, check out PDF).
