Abstract:The aim of this study was to identify characteristics that predispose older residents of Adelaide to falling. Information collected in the baseline phase of the Australian Longitudinal Study of Ageing was used to draw cross-sectional comparisons between participants who reported having fallen on at least one occasion in the previous 12 months and those participants who reported not having fallen. The baseline cohort consisted of 1947 participants aged 70 years or more, of whom 550 (28 per cent) reported having fallen at least once in the previous year. Independent risk factors for falling were: age; having left school at an early age; a worsening of vision in recent years; and histories of Parkinson's disease, fractured hip, glaucoma, stroke (including transient ischaemic attack), corns or bunions, or arthritis. The findings regarding medical histories suggest some possible opportunities for reducing the risk of falls in the elderly by managing the symptoms and risk factors of underlying conditions such as stroke and loss of vision.

Our purpose was to document and investigate the prognostic significance of features seen on MRI of patients with whiplash injury following relatively minor road traffic crashes. MRI was obtained shortly and at 6 months after the crash using a 0.5 T imager. The images were assessed independently by two radiologists for evidence of fracture or other injury; loss of lordosis and spondylosis were also recorded. Clinical examinations were used to assess the status of patients initially and at 6 months. The results of the independent MRI and clinical investigations were then examined for association using statistical tests. Initial MRI was performed on 29 patients, of whom 19 had repeat studies at 6 months; 48 examinations were thus examined. Apart from spondylosis and loss of lordosis, only one abnormality was detected: an intramedullary lesion consistent with a small cyst or syrinx. There were no statistically significant associations between the outcome of injury and spondylosis or loss of lordosis. No significant changes were found when comparing the initial and follow-up MRI. It appears that MRI of patients with relatively less severe whiplash symptoms reveals a low frequency of abnormalities, apart from spondylosis and loss of lordosis, which have little short-term prognostic value. Routine investigation of such patients with MRI is not justified in view of the infrequency of abnormalities detected, the lack of prognostic value and the high cost of the procedure.
