cervical spondylosis, myofascial pain syndrome, pain, prevalence, risk factors


Objectives: To determine the prevalence and characteristics of myofascial pain syndrome (MPS) in people diagnosed with cervical spondylosis and the correlation between these two conditions.

Study design: Retrospective study.

Setting: Outpatient Rehabilitation Clinic, Saraburi Hospital.

Subjects: Patients diagnosed with cervical spondylosis between March 1, 2019 and February 28, 2022.

Methods: Patient characteristics and general information were obtained from medical records. The level and severity of cervical spondylosis were determined from radiographic findings. Muscles of the neck, shoulder, arm, and hand areas diagnosed with MPS were used to determine the prevalence of MPS and to analyze correlations with cervical spondylosis and other related factors.

Results: Of the 281 patients with cervical spondylosis recruited, 71.5% were diagnosed with MPS and the average number of MPS-affected muscles was 2.29 per person. The severity of cervical spondylosis was statistically significantly associated with a diagnosis of MPS (p = 0.003). Those with a minimal degree of cervical spondylosis on radiographic study were approximately 13 times more likely to have a diagnosis of MPS than those with a gross degree; however, severity had a weak negative correlation with the number of MPS-affected muscles (r = -.224, p < 0.001). Multivariable logistic regression analysis demonstrated that less severe cervical spondylosis, female gender and lower body mass index were independent factors correlated with a diagnosis of MPS (p < 0.05). 

Conclusions: Patients diagnosed with cervical spondylosis have a high prevalence of concomitant MPS. Physicians need to be aware of the possibility of MPS when treating cervical spondylosis, especially if the patient is female, has a low BMI, and has less severe cervical spondylosis.
