Abstract:
Configurable orthoses having a high degree of independent adjustability of various parameters are provided. In the example of a rehabilitation-evaluation ankle-foot orthosis (REAFO), these parameters may include calf band anteroposterior, height, width, sagittal tilt, coronal tilt, and mediolateral displacement adjustments; mediolateral displacement adjustments of a supramalleolar support; heel width/stirrup separation adjustment; and sagittal active joint resistance and neutral angle adjustments. Calf band mediolateral displacement adjustment may be provided by a lockable four-bar pivoting frame linkage of the REAFO. In one aspect, the configurable orthosis is used in conjunction with a plastically deformable precursor member to facilitate the design and manufacture of a definitive orthosis customized for a particular patient. In another aspect, the orthosis communicatively transmits limb shape data to either a positive shape receiver apparatus or a CAD/CAM apparatus, to facilitate design and manufacture of a definitive orthosis.
