For clients WITH teeth or dentures:
For clients WITHOUT teeth or dentures:
Purpose of Exercise:
– Increase posterior pharyngeal wall movement in clients with reduced base of tongue to posterior pharyngeal wall approximation (seen on Videofluoroscopy / Modified Barium Swallow Study)
– Recent tongue surgery; do NOT perform this exercise and consult your physician for further advice
– May also be unsuitable long-term post tongue surgery, depending on type of surgery and/or flap reconstruction
Precautions / Tips:
– Do not perform this exercise with any food or drink
– Protruding the tongue further may be more effective, however may be more difficult to perform
– If triggering a swallow is difficult, perform a repetition of Thermal-Tactile Stimulation (TTS) immediately before the Masako swallow
– If feeling uncomfortable, release the tongue and rest as required
Note for clinicians:
– Evidence suggests the Masako exercise may decrease anterior hyoid movement. Therefore, it is recommended to train & prescribe an exercise to improve anterior hyoid movement, such as the Shaker’s Hyolaryngeal Excursion Exercise (SHEE)
