A motion assistance apparatus including a fixing module attached to a user, a driving module fixed to the fixing module to generate rotation power, a supporting module configured to support a portion of a body of the user and driven by the driving module, a sensor configured to measure a width of the fixing module, and a controller configured to adjust the rotation power of the driving module based on the measured width.

A three-dimensional (3D) digital image of an individual patient marked with target therapeutic locations on a skin surface of the patient is used for locating those treatment locations on a patient's skin for fascial manipulation and other treatments. The 3D image may be obtained by merging an unmarked 3D digital patient model image converted from a 2D optical image with a generic musculoskeletal digital model having optimized target therapeutic locations distributed over a skin surface thereof. The generic musculoskeletal digital model may be obtained from a library of such images.
