A proposed new classification system for whiplash associated disorders - implications for assessment and management

The development of chronic symptoms following whiplash injury is common and contributes substantially to costs associated with this condition. The currently used Quebec Task Force classification system of whiplash associated disorders is primarily based on the severity of signs and symptoms following injury and its usefulness has been questioned. Recent evidence is emerging that demonstrates differences in physical and psychological impairments between individuals who recover from the injury and those who develop persistent pain and disability. Motor dysfunction, local cervical mechanical hyperalgesia and psychological distress are present soon after injury in all whiplash injured persons irrespective of recovery. In contrast those individuals who develop persistent moderate/severe pain and disability show a more complex picture, characterized by additional impairments of widespread sensory hypersensitivity indicative of underlying disturbances in central pain processing as well as acute posttraumatic stress reaction, with these changes present from soon after injury. Based on this heterogeneity a new classification system is proposed that takes into account measurable disturbances in motor, sensory and psychological dysfunction. The implications for the management of this condition are discussed. (C) 2004 Elsevier Ltd. All rights reserved.

Ethics and health systems research in 'post'-conflict situations

Although considerable attention has been given to ethical issues related to clinical research in developing countries, in particular related to HIV therapy, there has been limited focus on health systems research, despite its increasing importance in the light of current trends in development assistance. This paper examines ethical issues related to health systems research in 'post'-conflict situations, addressing both generic issues for developing countries and those issues specific to 'post'-conflict societies, citing examples from the author's Cambodian experience. It argues that the destruction of health infrastructure results in a loss of structures and processes that would otherwise protect prospective research subjects who are part of vulnerable populations. It identifies the growth of health systems research as part of a trend towards sectoral and programmatic development assistance, the emergence of 'knowledge generation' as a form of research linked to development, and the potential for conflict where multilateral and bilateral donors are both primary funders and users of health systems research. It also examines the position of the health system researcher in relation to the sponsors of this research, and the health system being analysed.

Central hypersensitivity in whiplash: Implications for physiotherapy assessment and management

It is emerging that whiplash-associated disorder (WAD) is a complex condition characterised by a variety of physical and psychological features. Generalised sensory hypersensitivity is one of these features and its presence reflects augmented central pain processing mechanisms. Whilst most studies have investigated these processes in chronic WAD, it is becoming clear that in some of the whiplash injured, sensory disturbances are present from soon after injury, and are associated with both poor recovery and recalcitrance to multimodal physiotherapy interventions. Evidence for sensory hypersensitivity in WAD and possible underlying mechanisms of these phenomena are reviewed. Physiotherapists play an important role in the evaluation and management of whiplash injury. It is important that sensory disturbances be identified early in the clinical assessment of the whiplash injured patient and that ensuing management strategies address these changes, if the aim of treatment is to prevent the transition to chronicity.

The use of electropalatography in the assessment and treatment of acquired motor speech disorders in adults: Current knowledge and future directions

Electropalatography (EPG) has been employed to measure speech articulation since the mid-1970s. This technique has predominately been used in experimental phonetic research and in the diagnosis and treatment of articulation disorders in children. However, there is a growing body of research employing EPG to diagnose and treat articulatory impairment associated with acquired motor speech disorder (MSD) in adults. The purpose of this paper was to (1) review the findings of studies pertaining to the assessment and treatment of MSDs in adults using EPG, (2) highlight current methodologies employed, and (3) discuss the potential limitations of EPG in the assessment and treatment of MSDs and examine directions for future applied research and treatment studies.

Introducing evidence-based family assessment and therapy in child and youth mental health services: Applying systemic principles to maintain, sustain and build capacity

The purpose of this article is to overview the context of the mental health service in which we work, and family therapy's status prior to and after the impact of changes wrought by the introduction of the National Mental Health Policy. We then explore some key issues that we think contribute to the persistence of the occlusion of family therapy in child psychiatric services; and the strategies that we developed and are continuing to develop to support change, finally, we describe the use of a family assessment instrument that we believe is central to our change strategy.
