motor acts <strong>in</strong> preparation for the swallow. This def<strong>in</strong>ition encompasses the<br />

cognitive awareness of the upcom<strong>in</strong>g eat<strong>in</strong>g situation, visual recognition<br />

of food, and all of the physiological responses to the smell and presence<br />

of food such as <strong>in</strong>creased salivation. 8 Accord<strong>in</strong>gly, dysphagia affects the<br />

most basic of socio-biological functions – the ability to eat and dr<strong>in</strong>k. 9<br />

Some people who contracted polio dur<strong>in</strong>g the epidemic of the 1950s<br />

are now experienc<strong>in</strong>g <strong>in</strong>creas<strong>in</strong>g muscle weakness, <strong>in</strong>clud<strong>in</strong>g swallow<strong>in</strong>g<br />

difficulties, particularly those who suffered bulbar polio. 10 In addition,<br />

these polio survivors may not necessarily have had any swallow<strong>in</strong>g<br />

difficulties <strong>in</strong> their <strong>in</strong>itial bout of polio. 11 Some of the signs for dysphagia<br />

<strong>in</strong>clude:<br />

● un<strong>in</strong>tentional weight loss,<br />

● loss of <strong>in</strong>terest <strong>in</strong> eat<strong>in</strong>g,<br />

● cough<strong>in</strong>g or chok<strong>in</strong>g when eat<strong>in</strong>g,<br />

● food stick<strong>in</strong>g <strong>in</strong> the throat, and<br />

● difficulty swallow<strong>in</strong>g tablets. 12<br />

If one or more of these signs are present, the person should be referred for<br />

a more complete swallow exam<strong>in</strong>ation that may <strong>in</strong>clude an <strong>in</strong>strumental<br />

swallow<strong>in</strong>g assessment (e.g. videofluoroscopy (VFSS), flexible fiberoptic<br />

exam<strong>in</strong>ation of swallow<strong>in</strong>g (FEES)). The swallow<strong>in</strong>g difficulties<br />

displayed by these polio survivors <strong>in</strong>clude:<br />

● unilateral and bilateral pharyngeal wall weakness,<br />

● reduced tongue base retraction, and<br />

● reduced laryngeal elevation result<strong>in</strong>g <strong>in</strong> reduced closure of the<br />

laryngeal vestibule. 13<br />

All of these disorders can cause residue to rema<strong>in</strong> <strong>in</strong> various areas of the<br />

pharynx, with the risk of aspiration 14 after the swallow. Often, postural<br />

changes selected to match the person’s swallow physiology will facilitate<br />

a better swallow with reduced risk of aspiration. In most cases, aggressive<br />

exercise will fatigue the mechanism rather than strengthen it. 15 Therefore,<br />

compensatory strategies 16 are the procedure of choice.<br />
