Assist wear item, control method for controller of assist wear item, and recording medium

An assist wear item 4 is worn on a portion of a living body and has an inner surface brought into contact with the portion. The assist wear item includes assisting actuators 6, contact sensors 87, and a controller. Each assisting actuator is driven to expand and contract. The assisting actuators are linearly arranged along an expansion/contraction direction of a muscle at the portion. Each contact sensor detects a contact with an outer surface of the assist wear item. The contact sensors include a first contact sensor and a second contact sensor. The controller increases or decreases a driving power of expansion/contraction driving of an assisting actuator corresponding to a region ranging from the first contact sensor to the second contact sensor if the controller continuously receives a detection result indicating a contact from at least one contact sensor 87 between the first and second contact sensors during a certain time period.
