Effect of Craniocervical Flexion on Muscle Activities of Abdominal and Cervical Muscles during Pilates Hundred Exercise

Background Abdominal muscles are important for stabilizing the trunk and reducing stress on the lumbar spine. In patients with neck pain, the cervical deep stabilizing muscles are weak and the cervical superficial muscles, such as the sternocleidomastoid (SCM), are dominantly activated. Craniocervical flexion (CCF) activates the deep cervical stabilizing muscles and reduces overactivation of the SCM. Objectives The purpose of this study was to investigate the effect of CCF on the activity of the abdominal muscles and cervical muscles during pilates hundred exercise in 12 healthy people. Methods Before the intervention, measure the maximal voluntary isometric contraction (MVIC) of the right SCM and rectus abdominis (RA) muscles. The muscle activity of the SCM and RA is measured when performing the Hundred with and without CCF in random order. Results There were statistically significant differences in SCM and RA activity during hundred according to two different neck positions. When performing the hundred with CCF, the activity of the SCM muscle significantly decreased and the activity of the RA muscle significantly increased compared to the hundred without CCF. Conclusions When instructing the pilates hundred, performing it together with CCF will be a way to activate the deep stabilizing muscles of the neck and effectively strengthen the abdominal muscles.
