Falls in the elderly--clinician's approach.

Fall is an involuntary event producing a change in posture resulting in the individual adopting an unplanned supine position. Globally more than one-third of persons 65 years of age or older fall each year and in half of such cases the falls are recurrent. Several predisposing factors for such falls have been recognised like age related changes in posture control, reduced visual acuity, anxiety, drugs, environmental hazards and underlying neurological diseases. It is the interplay of predisposing and precipitating factors that really matter and not exactly a single cause. Evidence based interventions have been suggested from recent clinical trials and certain preventive guidelines are present to reduce the rate of falling, provided a periodic targeted approach is followed.
