Whiplash Associated Disorder may have varied signs and symptoms in patients, many of which go unreported. The most notable symptom is neck pain. Other symptoms include headache, sleep problems, reduced range of motion, numbness, poor concentration, vision problems, tinnitus (ringing in the ears), fatigue/weakness, depression, and other associated pains such as shoulder, arm and jaw pain.
In a Swedish study conducted in 1105 patients, symptom patterns were reviewed over a 6 month period following the injury. The study also compared differences in symptoms between men and women. Patients completed a baseline questionnaire and a follow-up questionnaire.
The baseline questionnaire was completed on average 18.2 days following the motor vehicle collision and follow up 206.8 days following the collision. Most patients reported neck pain following the accident (98.3% in men and 99.3% in women), however on completion of the baseline questionnaire the prevalence was 81.4% in men and 84.7% in women and further reduced to 44% and 45%, respectively, at follow up.
