[Purpose] This study was conducted to compare and analyze influence of craniocervical
flexion and suboccipitalis relaxation in cervicogenic headache patients of their cervical
muscular fatigue, tone, and headache intensity. [Subjects and Methods] 30 patients with
cervicogenic headache were selected and 10 subjects per group were randomly assigned to
control group, craniocervical flexion exercise group, and suboccipitalis relaxation group.
Intervention for each group was provided 5 times a week for 4 weeks. Muscular tone test
and muscular fatigue test were conducted on both sides of upper trapezius and
sternocleidomastoideus and visual analogue sclae on the headache intensity was conducted
before the intervention, after 2 weeks, and after 4 weeks. [Results] Difference from
intervention was significant in muscular fatigue of upper trapezius and
sternocleidomastoideus, muscular tone of sternocleidomastoideus, and headache intensity.
Correlation between intervention duration and the groups showed significant difference in
muscular fatigue, muscular tone, and headache intensity except left upper trapezius
muscle. [Conclusion] From this study, 4 week application of crainiocervical flexion
exercise and suboccipitalis relaxation on cervicogenic headache patients was found to be
effective in decrease of muscular fatigue of upper trapezius and sternocleidomastoideus,
muscular tone of sternocleidomastoideus, and headache intensity.
