Applying braces to the legs in the rehabilitation of hemiplegic patients calls for discrimination. A brace that aids in standing may hinder walking; a patient who needs the knee support of a long brace at first may eventually become able to walk as well with either a short leg brace or none at all. The history of a 61-year-old man after sudden onset of total right-sided paralysis and aphasia illustrates the importance of frequent, apparently minor adjustments in determining the progress of the patient. Bracing is a significant consideration in the management of some hemiplegic patients. When it is necessary, a prompt and judicious choice should be made among devices of the kind here described, and frequent inspection and adjustment may be necessary.
