Comparison of the range of cervical spine movements between individuals with and without shoulder pain: a cross-sectional study

Abstract

Shoulder pain is a very common complaint in the clinical setting and, in general, presents joint reduction of joint mobility. As with the complaint in the shoulder, cervical spine dysfunctions also present this signal and symptom. Some studies prove the functional connection between the cervical spine and the shoulder, but there is no study showing whether patients with shoulder pain have any restrictions on movement of the cervical spine. Therefore, the purpose of this study will be to compare the values of the amplitude of the movements of the cervical spine between subjects with and without pain in the shoulder. For this, individuals of both sexes between the ages of 35 and 65 will be selected. The volunteers will be divided into two groups, the group with shoulder pain (GD) and the second group without shoulder pain, called the control group (CG). An evaluation form will be applied to characterize the subjects. The index questionnaire and inability of shoulder pain SPADI - BR will be used to verify the functionality of the shoulder. The cervical range of motion (ROM) will be measured with the Cervical Range of Motion (CROM) instrument. The movements of flexion, extension, right and left lateral tilt, rotation to the right and left, with standardized orientations and corrections of compensatory movements will be evaluated. Three repetitions of each of the cervical movements will be measured. The One-Way ANOVA statistical test will be used to compare the ROMs of cervical spine movements between the two groups. Pearson's correlation will be used to verify the relationship between each of the cervical ROMs with the shoulder dysfunction index (total SPADI score). The level of significance adopted will be pd0.05. It is hypothesized that individuals with shoulder dysfunction have some decrease in cervical spine ROM and a moderate to strong correlation between ROM values and shoulder pain and disability index (total SPADI score).
