Purpose[edit | edit source]
.jpeg)
The diaphragm is the primary muscle of respiration, when it is functioning normally it produces observable breathing mechanics of abdominal motion, anterior-superior chest expansion, and lateral rib expansion, commonly referred to as “diaphragmatic breathing”.[1]
The Hi-Lo Test is used in the assessment of breathing pattern dysfunction, by the observation of abdominal excursion and anterior-posterior chest expansion.[1]
Technique[edit | edit source]
The patient is instructed to place one hand on their chest and the other on their abdomen and breathe normally. Movement in the upper chest and abdomen is observed.[1]
The patients who functionally breathe display visible abdominal expansion movement and no visible superior migration of the thoracic cage.[1]
The test can be done in different positions according to the patient. From supine, sitting or standing.
One study at 2019 looked into the effect of different positions on Hi-Lo test results, it found that as postural demand increased from sitting to standing, frequency of functional breathing decreased, due to increased demand on the diaphragm. Which suggests that Hi-Lo test should be performed from different positions to determine whether the diaphragm is able to respond to increased postural demands.
Evidence[edit | edit source]
One study compared Hi-Lo test with MARM (Manual Assessment of Respiratory Motion), it found that less experienced practitioners with only a small amount of practice and training can use the MARM and Hi Lo with similar levels of accuracy to experienced practitioners.[3]
