Postural changes are commonly used treatment to prevent the elderly from the risk of aspiration pneumonia. However, the evidence-based studies regarding effectiveness of this treatment remains unclear since no systematic method exists to measure constantly changing postures without disturbing usual eating behaviors. In this paper, using IMU system attached to a smart-phone based wearable technology, we analyzed data of the neck orientation angles obtained from the dysphagia patients and healthy adults during their mealtime and attempted to see if the obtained data can show differences regarding the dynamics of the angles.The result shows the possibilities to use the device to monitor neck orientations while the dysphagia patients eating their meals in daily lives.
