OBJECTIVE: To configure an auxiliary equipment to allow videofluoroscopic study of swallowing and related disorders without the patients' active collaboration in obtaining the required positions, with reproducibility of views, postures and maneuvers needed for the examination, in spite of limitations imposed by associated diseases. MATERIALS AND METHODS: A Philips BV-22 C-Arm was utilized, with adaptation implemented to allow simultaneous images recording on both digital and analog media. Primary and secondary chairs were specially designed, built and attached to the equipment. RESULTS: Adults and children could be appropriately seated and all necessary radiographic views could be obtained without active positioning or cooperation from the volunteers. Additionally, a calibration system was developed, allowing the input of dimensional parameters for quantification of recorded phenomena. CONCLUSION: The videofluoroscopy utilization spectrum could be extended to agitated patients, and those with behavior similar to patients affected by neuromotor disorders, with greater effectiveness and consequently with lower radiation exposure time.
