- Reduced cervical range of motion (ROM) is a common finding in people with neck pain. With few exceptions, only the angle between head and thorax has been measured. Our aim was to use an extended model to compare active cervical flexion and extension, separate for upper and lower cervical levels, between people with chronic non-traumatic neck pain and controls. We also investigated associations between ROM measures, symptoms and self-rated functioning. In this cross-sectional study, 102 subjects with neck pain and 33 healthy controls participated. An electromagnetic tracker system was used to measure the kinematics to construct a three-segment model including the thorax, cervical spine and head. Neutral flexion/extension were defined at subjects’ self-selected seated posture. We found that in the neck pain group, extension in the upper cervical levels and predominately flexion for the lower levels were reduced. The ratio between ROM for the upper and lower levels was altered in the neck pain group so that the lower levels contributed to a lesser extent to the total sagittal ROM compared to controls. These findings could not be explained by a greater forward head posture but must have other origins. For the neck pain group, ROM measures were weakly associated to pain and self-rated functioning. Altogether, this implies that using a three-segment model for assessment of ROM can be a valuable improvement for characterisation of patients and treatment evaluation.

- Objective: To evaluate the slow and fast components of postural control in quiet stance in subjects with chronic neck pain, associations between postural sway and self-rated characteristics and to study the impact of anthropometrics on postural sway.Design: A single-blinded cross-sectional study including two separate data collections.Subjects: Sample 1: Persons with chronic non-specific neck pain (NS, n=24), whiplash associated disorders (WAD, n=21). Healthy subjects were controls (CON, n=21). Sample 2: Women only, 98 NS and 32 CON subjects.Methods: Subject performed a quiet stance test with eyes closed on a force platform while the center of pressure (CoP) trajectory was measured. Sample 1 was tested on a firm surface for 30 seconds, while sample 2 was tested on both firm and foam surfaces for 190 seconds. The CoP signal was decomposed into the slow and fast components and the magnitude of these signals were calculated. Anthropometrics were included as covariate in the analysis of group differences if correlated with postural sway variables. Group differences in the sway variables were evaluated, as well as association between postural sway and self-ratings of symptoms, functioning and kinesiophobia.Results: Increased magnitude of the slow sway component was found for both neck pain groups. Increasing age was associated with increased magnitude of the fast component. Surface conditions had no effect on group difference. For WAD, associations were found between the magnitude of the slow component and self-rated characteristics related to physical functioning, sensory alterations and psychosocial functioning. For NS, concurrent low back pain was associated with increased postural sway.Conclusion: Postural control can be altered in chronic neck pain. This effect was present only for the slow sway component, which implies aberration in sensory feedback or processing of sensory information. Associations between postural sway and self-rated characteristics in WAD support the clinical validity of postural control assessment in this group. Increased postural sway found in NS with concurrent low back pain suggests an important role of generalised spinal pain on postural control alterations.

- The purpose of this pilot study was to evaluate sensorimotor functions in patients with chronic neck pain with objective and quantitative methods. A group of 16 patients with chronic idiopathic neck pain of insidious onset or whiplash associated disorders (WAD) was compared to an equally sized group of healthy subjects. Kinematics were investigated during voluntary head rotations by measuring range of motion, variability of range of motion (ROM-Variability), peak velocity, and smoothness of movement (jerk index). Repositioning acuity after cervical rotations was evaluated by analysing constant and variable error (VE). In comparison to the healthy subjects, the patients showed significantly larger jerk index, ROM-Variability and VE. No statistically significant differences were found between insidious neck pain and WAD. It is concluded that jerky and irregular cervical movements and poor position sense acuity are characteristic sensorimotor symptoms in chronic neck pain. The observed individuality in sensorimotor disturbances emphasizes the importance of developing specific rehabilitation programs for specific dysfunctions, and of using objective and quantitative methods for evaluation of rehabilitation.
