PMID 29184301WHAT IT FOUND
Adding chin tucks to neck stretching lowered muscle stiffness and improved head posture more than stretching alone in people with cervicogenic headache.
Muscle tightness also decreased, but the change was not large enough to be considered a clear benefit over stretching by itself.
Key findings
01The group that added cranio-cervical flexion exercises to stretching showed significantly greater reductions in muscle stiffness in the suboccipital and upper trapezius muscles compared to the stretching-only group.
02The group that added cranio-cervical flexion exercises showed a significantly greater improvement in forward head posture, measured by the craniovertebral angle, compared to the stretching-only group.
03Although muscle tone decreased in both groups, the difference between the stretching-only group and the group adding exercises was not statistically significant.

What it does not show
The study had a small sample size of 30 participants. The intervention lasted only three weeks, so long-term effects are unknown. The study measured physical changes like muscle tone and posture but did not report on pain levels or headache frequency, which are the primary concerns for patients.
The easy way to misread this
Do not assume that adding chin tucks will reduce pain more than stretching alone. The study measured physical properties like stiffness and posture, not pain or headache symptoms, and the change in muscle tone was not significantly different between the groups.
