Spinal Posture, Mobility, and Muscle Endurance in Women With Tension‐Type Headache: A Case‐Control Study

Background Tension‐type headache (TTH), a prevalent form of primary headache, has been linked to alterations in spinal biomechanics. Objective This study aimed to compare spinal posture, mobility, and muscle endurance between women with and without TTH. Methods This case‐control study included 68 women aged 18–55 years with ( n = 34, age = 20.51 ± 1.73 years, BMI = 22.03 ± 2.90 kg/m 2 ) and without ( n = 34, age = 19.91 ± 0.99 years, BMI = 21.38 ± 2.99 kg/ m 2 ) TTH. Posture (craniovertebral angle) and mobility (range of motion) of the cervical region were evaluated with a goniometer and posture and mobility of the thoracic and lumbar and sacral regions in the sagittal plane were evaluated with the Spinal Mouse device (IDIAG M360, Fehraltorf, Switzerland), cervical region muscle endurance was evaluated with cervical flexion and extension endurance tests and the craniocervical flexion test, and trunk muscle endurance was evaluated with McGill’s trunk muscle endurance tests and the Sahrmann test. Results Cervical flexion (95% CI: −1.38 to −0.40, d = 0.90, p ≤ 0.001) and extension (95% CI: −2.02 to −0.97, d = 1.50, p ≤ 0.001) mobility and cervical flexor (95% CI: −1.49 to −0.49, d = 0.99, p ≤ 0.001) and deep neck flexor muscle endurance (95% CI: −1.64 to −0.61, d = 1.13, p ≤ 0.001) scores were lower in women with TTH compared to the healthy controls. It was also observed that the thoracic angle (95% CI: 0.11 to 1.08, d = 0.60, p = 0.015) was higher in the sagittal plane and trunk flexor (95% CI: −1.33 to −0.35, d = 0.84, p = 0.001) and trunk right/left lateral flexor muscle endurance (95% CI: −1.75 to −0.73, d = 1.24, p ≤ 0.001)/(95% CI: −1.76 to −0.73, d = 1.25, p ≤ 0.001) and trunk core stability ( p = 0.003) scores were lower. Conclusion Cervical mobility was less and cervical muscle endurance was lower in women with TTH, but their cervical postures were similar. It was also observed that thoracic angle was higher in sagittal plane and trunk muscle endurance was lower.
