Participants between the ages of 18-64 who were diagnosed with cervical myofascial pain syndrome will be included in the study. cervical sagittal parameters, numerical pain rating scale, Bournemouth neck questionnaire and cervical range of motion will be measured and evaluated.

It is an observational, cross-sectional study. Participants between the ages of 18-64 who were diagnosed with cervical myofascial pain syndrome, who applied to the Physical Medicine and Rehabilitation Clinic of Kanuni Sultan Süleyman Training and Research Hospital with neck pain for more than 3 months will be included. The pain level of the participants will be evaluated with the numerical pain rating scale, the cervical range of motion and the disability level with the Bournemouth neck questionnaire. C0-2 cervical lordosis angle, C2-C7 cervical lordosis angle, cervical sagittal vertical axis (cSVA), T1 slop, T1 slop - cervical lordosis angle (TS-CL), cervical tilt, thoracic inlet angle (TIA) and Cranial tilt measurement will be performed by using Surgimap software program. The relationship between the level of pain and disability, and cervical sagittal parameters will be evaluated.
