Elderly inpatients: postural reflex impairment.
We examined postural reflexes in 50 patients in a geriatric care facility. Patients aged 60 years and older who did not have orthostatic hypotension were subjected to a standing postural perturbation, and the degree of postural instability was recorded. Sixteen patients with leg amputations, recent stroke, and leg deformities were excluded. Of the remaining 34 patients, 44% had severe postural reflex impairment, and 24% had moderate impairment. Although the etiology for postural reflex impairment may be multivariant, the high percentage suggests that postural reflex dysfunction may be an important cause of unexplained falls in the elderly.
