Excerpt
The effects of compensatory strategies to improve swallow safety and/or efficiency have been examined and described since the late 1970s. These strategies have included the use of postures, bolus modifications, and sensory enhancements. Many of these early studies were conducted by Jeri Logemann, Ph.D, a pioneer in the field of dysphagia, and the many researchers in her Swallow Physiology Lab at the Northwestern University. These early studies paved the way for others who examined similar rehabilitation strategies, using sophisticated and higher-tech procedures, often obtaining results that confirmed or supported those found by Dr. Logemann et al. The compensatory strategies discussed in this review are based on information gleaned over the years about systematic shifts in oropharyngeal swallow physiology with bolus modification and postures, as well as changes to bolus flow during the swallow. Implementation of these strategies has historically been based on instrumental examination of oropharyngeal swallowing, using the modified barium swallow (MBS) procedure, as well as the flexible endoscopic examination of swallowing [

3], both of which are used as (a) diagnostic tools to identify the neuromuscular physiologic components of the swallow disorder; and (b) rehabilitation tools to identify the optimal therapeutic strategies that result in a safer and/or more efficient swallow. Newer technologies, particularly high-resolution manometry, transmagnetic stimulation, and fMRI have supported the utility of these therapeutic strategies, including bolus modifications, postures, and sensory enhancements. …
