[Music] circumduction is characterized by a wide Arc made by the prosthetic limb which occurs in the transverse plane and is best viewed in the coronal plane if the knee flexion resistance is Extreme or another limitation of flexion exists the individual must circumduct the prosthesis to provide four-foot clearance and swing phase thus careful adjustment of the flexion resistance of the knee is necessary to avoid this deviation an individual may also circumduct as an antalgic gate mechanism when the medial brim of the socket impinges the tissues during swing phase an improper brim radius or an excessively High medial brim may cause this deviation circumduction may occur when the prosthesis has been excessively lengthened when this occurs an examination of components and socket fit will determine if an incorrect length is causing the individual to circumduct this deviation may also be caused by an extension assist that is too strong
