Method of clearing a biological airway using a self-contained portable positionable oscillating motor array

A method of clearing a biological airway, comprising:

• positioning a first wearable harness on a torso of a subject;
• positioning a second wearable harness on a torso of a subject over at least a portion of an outer surface of the first wearable harness;
• selectively positioning at least some of a plurality of engines on and/or adjacent at least one treatment area, wherein at least one of the plurality of engines is releasably couplable to the first wearable harness or the second wearable harness such that the at least one of the plurality of engines is positionable relative to the subject using a positioning system;
• applying an oscillation force to at least one of the treatment areas using at least some of the plurality of engines;
• adjusting the oscillation force applied by at least some of the activated plurality of engines to the treatment area by activating the second wearable harness;
• mobilizing at least some secretions in an airway within the subject substantially adjacent the at least one treatment area;
• and
• assessing treatment areas of the subject's chest for selective placement of at least some of the plurality of the engines, such that the at least some of the plurality of engines are adjacent treatment areas that need secretion mobilization, wherein assessing treatment areas comprises using a controller to assess where to reposition the at least some of the plurality of engines after data is gathered after the initial placement.
