Predictors of outcome following whiplash injury are limited to socio-demographic and symptomatic factors, which are not readily amenable to secondary and tertiary intervention. This prospective study investigated the predictive capacity of early measures of physical and psychological impairment on pain and disability 6 months following whiplash injury.(More)
STUDY DESIGN Cross-sectional investigation of muscle changes in patients suffering from persistent whiplash-associated disorders (WAD). OBJECTIVES To quantitatively compare the presence of fatty infiltrate in the cervical extensor musculature in a cohort of chronic whiplash patients (WAD II) and healthy control subjects across muscle and cervical(More)
OBJECTIVE To investigate the efficacy of physiotherapy compared with a wait and see approach or corticosteroid injections over 52 weeks in tennis elbow. DESIGN Single blind randomised controlled trial. SETTING Community setting, Brisbane, Australia. PARTICIPANTS 198 participants aged 18 to 65 years with a clinical diagnosis of tennis elbow of a(More)
Dysfunction in the motor system is a feature of persistent whiplash associated disorders. Little is known about motor dysfunction in the early stages following injury and of its progress in those persons who recover and those who develop persistent symptoms. This study measured prospectively, motor system function (cervical range of movement (ROM), joint(More)
OBJECTIVE To compare the clinical efficacy of foot orthoses in the management of patellofemoral pain syndrome with flat inserts or physiotherapy, and to investigate the effectiveness of foot orthoses plus physiotherapy. DESIGN Prospective, single blind, randomised clinical trial. SETTING Single centre trial within a community setting in Brisbane,(More)
OBJECTIVE To determine if differences exist in reported symptoms and in outcomes of sensorimotor tests (cervical joint position error [JPE], neck-influenced eye movement control, postural stability) between subjects with persistent whiplash and subjects with unilateral vestibular pathology associated with acoustic neuroma. DESIGN Repeated measures, case(More)
The aim of this study was to obtain, using Magnetic Resonance Imaging (MRI), muscle volume measurements for the gluteus maximus (upper: UGM and lower: LGM portions) and tensor fascia lata (TFL) muscles in both healthy subjects (n=12) and those with unilateral osteoarthritis (OA) of the hip (mild: n=6, and advanced: n=6). While control group subjects were(More)
The primary objective of this study was to assess the lingual kinematic strategies used by younger and older adults to increase rate of speech. It was hypothesised that the strategies used by the older adults would differ from the young adults either as a direct result of, or in response to a need to compensate for, age-related changes in the tongue.(More)
The availability of lysine and the ileal digestibility of amino acids in three cottonseed meals and a soya-bean meal for grower/finisher pigs were determined. The usefulness of the availability estimates for formulating diets was assessed. The availability of lysine, as assessed with a slope-ratio assay, was (proportion of total): cottonseed meal no. 1,(More)
1. The availability of lysine for pigs, rats and chicks was determined using samples of meat and bone meal (MBM) subjected to different pressure and temperature treatments during dry-rendering processing. The relation between slope-ratio estimates and three chemical tests for estimating 'available' lysine was assessed. 2. The availability of lysine(More)
