Manual therapy refers to various techniques used to address joint restrictions and soft tissue dysfunction. It differs from chiropractic adjustments in that the movements are slower and use less force. Sometimes referred to as joint mobilization, manual therapy techniques are used to stretch contracted muscles, impart more range of motion to a joint, and re-set disarticulated joints. The techniques can be passive (patient does not engage muscles during the procedure), active (patient is asked to move the treated body part during the procedure), or active-resistant (patient applies a resistive force during the procedure).
