Numerous studies investigating dissociative posttraumatic stress disorder (D-PTSD) have emerged. However, there is a lack of studies investigating D-PTSD following a wider range of traumatic exposure. Thus, the present study investigates D-PTSD using latent class analysis (LCA) in sub-acute patients of whiplash and associated risk factors. The results of LCA showed a three-class solution primarily distributed according to posttraumatic stress disorder (PTSD) symptom severity and thus no indication of D-PTSD...

[Purpose] To present the case of the non-surgical restoration of cervical lordosis in a patient suffering from chronic whiplash syndrome including chronic neck pain and daily headaches resulting from previous whiplash. [Subject and Methods] A 31 year old female presented with a chief complaint of chronic neck pain and headaches for 12 years, correlating temporally with a sustained whiplash. These symptoms were not significantly relieved by previous chiropractic spinal manipulative therapy. The patient had cervical hypolordosis and was treated with Chiropractic BioPhysics® protocol including extension exercises, manual adjustments and cervical extension traction designed to increase the cervical lordosis...

Whiplash is a bony or soft tissue injury resulting from an acceleration-deceleration energy transfer in the neck. Although patients with whiplash injury often complain of cerebral symptoms, and previous studies have reported evidence indicating brain injury, such an association has not been clearly elucidated. Traumatic axonal injury (TAI) is tearing of axons due to indirect shearing forces during acceleration, deceleration, and rotation of the brain or to direct head trauma. Diffusion tensor imaging (DTI) has a unique advantage to detect TAI in patients whose conventional brain CT or magnetic resonance imaging (MRI) results were negative following head trauma...

Flagellate dermatitis (FD) exhibits a striking clinical appearance similar to whiplash marks. General dermatologists are likely to encounter this clinical appearance as a more localized presentation of phytophotodermatosis. Jellyfish stings may also cause localized linear or FD. Chemotherapeutic agents such as bleomycin, doxorubicin, docetaxel, and trastuzumab are well-recognized causes of a widespread FD and it may more rarely be seen in connective tissue disease such as dermatomyositis or Still disease. In our case, this was a presentation of shiitake mushroom dermatitis...

PURPOSE: The long-term outcome of Whiplash-associated disorder (WADs) has been reported to be poor in populations from medical settings. However, no trials have investigated the long-term prognosis of patients from medico-legal environment. For this group, the "compensation hypothesis" suggests financial compensation being associated with worsened outcome. The aims of this study were to describe long-term (2-4 years) non-recovery rates in participants with WAD recruited from insurance companies and to investigate the association between self-reported non-recovery and financial compensation...

Introduction: The presence of post-traumatic stress disorder (PTSD) symptoms has been found to be associated with an increased risk of persisting neck pain and disability in motor vehicle crash (MVC) survivors with whiplash injuries. The findings are mixed as to which PTSD symptom(s) best predicts recovery in this population. Objectives: The aims were (1) to explore the factor structure of the Post-traumatic Stress Diagnostic Scale (PDS) in a sample of acute whiplash-injured individuals following a MVC and (2) to identify the PTSD-symptom clusters that best predict long-term neck pain-related disability in this population as measured by the Neck Pain Disability Index (NDI)...

Until now, only reliability and validity of the English version of the modified perceived deficits questionnaire (mPDQ) have been investigated. The aim of this study was to translate the mPDQ into Dutch and evaluate its validity and reliability as an assessment tool for self-perceived cognitive problems in patients with chronic whiplash associated disorders (CWAD), chronic idiopathic neck pain (CINP) and fibromyalgia (FM). A case-control study was performed with a volunteer sample of 13 women with CWAD, 18 with CINP, 33 FM women and 33 healthy pain-free women...

BACKGROUND: The objectives of the current study were to investigate (1) the longitudinal, reciprocal associations between pain and post-traumatic stress symptoms as proposed by the mutual maintenance model, and (2)  to assess the predictive value of the three clusters of post-traumatic stress, where the model revealed that post-traumatic stress symptoms maintained pain in a consecutive cohort of whiplash-injured. METHODS: Participants (n = 253; 66.4% women) were people with WAD grades I-III following motor vehicle crashes in Australia...

PURPOSE: Motor vehicle accidents (MVAs) are a pandemic associated with human suffering and a burden to national economies. Whiplash-associated disorders (WADs) after MVAs are associated commonly with disability claims, many of which are related to vision. Convergence insufficiency (CI) leads to visual disability associated with symptoms of ocular discomfort. We examined the incidence of symptoms and findings consistent with CI in a cohort of patients after MVA-related WAD compared with age-matched control participants...

Jellyfish-induced gill pathology relies upon occasional diagnostic observations yet the extent and impact of jellyfish blooms on aquaculture may be significant. Idiopathic gill lesions are often observed in apparently healthy fish. This study exposed Atlantic salmon (Salmo salar L.) smolts to macerated Cyanea capillata at 2.5 and 5 g/L for 2 hr under controlled laboratory conditions. Blood chemistry and gill histopathology were examined over a subsequent 4-week period. Fish showed an acute response to the presence of jellyfish, including characteristic external "whiplash" discoloration of the skin and acute increases in blood electrolytes and CO2 concentration; however, these were resolved within 4 days after exposure...

BACKGROUND: Whiplash-associated disorders (WAD) are an enormous and costly burden to Australian society. Up to 50% of people who experience a whiplash injury will never fully recover. Whiplash is resistant to treatment and no early management approach has yet been shown to prevent chronic pain. The early presence of central sensitization is associated with poor recovery. Pregabalin's effects on central sensitization indicate the potential to prevent or modulate these processes after whiplash injury and to improve health outcomes, but this has not been investigated...

OBJECTIVES: Loss of motion following spine segment fusion results in increased strain in the adjacent motion segments. However, to date, studies on the biomechanics of the cervical spine have not assessed the role of coupled motions in the lumbar spine. Accordingly, we investigated the biomechanics of the cervical spine following cervical fusion and lumbar fusion during simulated whiplash using a whole-human finite element (FE) model to simulate coupled motions of the spine. METHODS: A previously validated FE model of the human body in the driver-occupant position was used to investigate cervical hyperextension injury...

Brain alterations are hypothesized to be present in patients with chronic whiplash-associated disorders (CWAD). The aim of this case-control study was to examine alterations in cortical thickness and white matter (WM) structure, and the presence of brain microhemorrhages in a patient group encountering chronic neck pain of traumatic origin (i.e., CWAD) when compared with a patient group characterized by nontraumatic chronic neck pain [i.e., chronic idiopathic neck pain (CINP)], and healthy controls. Furthermore, we aimed to investigate associations between brain structure on one hand and cognitive performance and central sensitization (CS) on the other hand...

BACKGROUND: Whiplash Associated Disorders (WAD) are common and costly, and are usually managed initially by general practitioners (GPs). How GPs manage WAD is largely unstudied, though there are clinical guidelines. Our aim was to ascertain the rate of management (percentage of encounters) of WAD among patients attending Australian general practice, and to review management of these problems, including imaging, medications and other treatments. METHODS: We analysed data from 2013 to 2016 collected by different random samples of approximately 1000 general practitioners (GPs) per year...

Purpose: Accommodative spasm, which manifests as ciliary muscle spasm, convergent strabismus or miosis, is a recognised consequence of head trauma. In whiplash cases, cervical spine hyperextension poses a risk of contra-coup injury and brainstem trauma, and is known to affect the visual system. However, to date, no cases of accommodative spasm due to whiplash injury have been reported. Observations: We present the case of a 34-year-old female who developed sudden onset blurred distance vision after a rear impact car crash, having previously been emmetropic...
