Pneumatic orthosis PILOT STUDY;.

The pneumatic orthosis is potentially a substitute or replacement for conventional long-ler and under outer clothing. Pneumatic tubes are incorporated into the orthosis and may be inflated at will by the patient. In a preliminary test it was found to be lighter, more comfortable and cosmetically more acceptable than conventional braces. This paper presents the results of the first pilot study of the orthosis in the United States, conducted by the New York Medical College--Bird S. Coler Hospital Department of Rehabilitation Medicine, using 11 patients with different levels of cord transection. The orthosis was tested for its effect in the following areas: pulmonary function, blood chemistries to determine calcuyn function and phosphorus metabolic retention or loss; spasticity; urinary tract studies; skin; systemic blood pressure and pulse; physical comfort; and effect of temperature and humidity on patient. Wearing time was increased daily until a patient tolerated a minimum of one hour of inflation and six to eight hours of deflation comfortably without negative results. All the patients tested tolerated daily use of the pneumatic orthosis up to six to eight hours with no harmful effect on the skin. It did not interfere with healing of existing decubiti. Use of the pneumatic orthosis prevented postural hypotension in all tested cases, facilitated urinary outflow, increased vital capacity and reduced spasms related to postural changes.
