Brief Summary
Neck pain-associated disorders (NAD) and whiplash-associated disorders (WAD) are major health problems. NAD has a lifetime prevalence of 54%. Although the majority of patients recovers within the first three months, a minority develops persistent pain. WAD, in contrast, is reported less frequently, but patients are often suffering more badly. Patients with chronic symptoms represent a considerable burden in terms of pain, suffering, health care needs, and social costs. Findings on the natural course of NAD and WAD reflect the necessity to identify factors besides pain related to the persistence of symptoms. First, alterations of input and processing of multiple sensory modalities causing movement control impairment can result in persistent symptoms and affect the quality of life. Besides, findings of psychosocial factors predictive of pain outcomes support the growing body of research proposing a bidirectional relationship between somatic and psychosocial variables. In particular, there is a pressing need to investigate pain-related activity patterns, besides fear-avoidance behavior in NAD and WAD. Maladaptive activity pattern have an impact on on pain and disability in the long-term prognosis. Mt important, given the high prevalence of NAD and WAD, the cortical representation of the cervical spine has not yet been investigated and, reports on neuroplasticity remain scarce. These shortcomings should be addressed to provide evidence for the temporal aspect of neuroplasticity and its involvement in pain persistence. Hypotheses: We hypothesize I. that impaired sensorimotor abilities, mental health at baseline increase pain intensity and disability during measurement. II. that maladaptive pain-related activity patterns avoidance and overactivity at baseline are prognostic factors for pain persistence and disability. III. that the WAD cohort shows more depression, anxiety and stress compared to the NAD cohort.

Outcome Measures
Primary Outcomes (2)
Pain intensity
Numeric Rating Scale (NRS). The NRS is a single 11- point numeric scale ranging from 0 to 10, with 0 representing "no pain" and 10 representing "worst pain you can imagine".
1 year
Disability
German version of the Neck Disability Index (NDI-G). The self-administered questionnaire consists of 10 items referring to various activities (personal care, lifting, driving, work, sleeping, concentration, reading, recreation) and pain (pain intensity, headache) with 6 possible answers per item. Each item is scored from 0 (no pain and no functional limitation) to 5 (worst pain and maximal limitation) points resulting in a minimal score of 0 points (no disability) to a maximum possible score of 50 points (totally disabled)
1 year
Study Arms (2)
Neck Pain-Associated Disorders
neck pain without an acceleration-deceleration mechanism
Whiplash-Associated Disorders
neck pain resulting from a traumatic acceleration-deceleration mechanism and classified as WAD Grade I-III on the modified Quebec Task Force Scale
Interventions
there are no interventions planned, we observe the patients in a cohort study which is named inception cohort study because we test participants before the condition develops.
Eligibility Criteria
Subjects with acute NAD or acute WAD, 18-65 years old with the ability to read, write, and understand German.
You may qualify if:
- In recurrence, no pain in the previous three months
- Age between 18 and 65 years at baseline
- Ability to read, write, and understand German for completing the questionnaires.
You may not qualify if:
- For both cohorts; a clinically relevant anatomical anomaly in the cervical spine (e.g., carcinoma), spine surgery; peripheral or central neurological illness, pregnancy, or women who gave birth in the last year (to avoid the confounding effects of pregnancy-related NAD)
- For the WAD cohort, WAD Grade IV on the modified Quebec Task Force Scale (Fracture of dislocation), patients who lost consciousness due to the traumatic event and post-traumatic amnesia to exclude mild traumatic brain injury.
