Approximately 6% (396, 476, 085) of the world's population (6, 607, 934, 746) has dysphagia. The incidence of dysphagia is particularly significant in acute care settings (25 ~ 45%) and long-term care units (50%). 1 in 17 people will develop dysphagia in their lifetime. 50 ~ 75% of stroke patients and 6 ~ 70% of patients under going radiation therapy for head and neck cancer will develop dysphagia. It is estimated that dysphagia prevalence in neurological disease such as Parkinson's Disease and ALS may be as high as 90%. 75% of nursing home residents exhibit some form of dysphagia and half of over 60 millions Americans over the age of 60 will experience dysphagia at some point after age 60. Most importantly dysphasia has a profound impact on the quality of life. Researchers from around the world continue to advance our understanding of normal swallowing (deglutition) and dysphagia and to develop advanced methods for the evaluation and treatment of dysphagia. In this article we will examine the research trends in swallowing and dysphagia and will explore recent advances in the normal swallow physiology and swallow pathophysiology as well as recent advances in evaluating deglutition, management of dysphagia in adults and children as well as recent efforts to reduce healthcare costs and increase the provisions of healthcare services through the use of pervasive healthcare technologies. The growth in published research supports the need for increased interdisciplinary research, expansion of the number of randomized controlled clinical trials of devices, methods of diagnosis and therapeutic protocols. Of special need is increased research on normal pediatric swallow and feeding physiology, pediatric swallow pathophysiology, advanced pediatric diagnostic methods, and advanced pediatric treatment methods. In addition, as clinical practice changes along with advanced pervasive health technology more research on the efficacy of pervasive health technology in speech and language pathology.
