Glossary
Abducted/abduction:
joint movement away from the midline of the
body along the transverse (horizontal) plane.
Adducted/adduction:
joint movement towards the midline of the
body along the transverse (horizontal) plane.
Anterior:
located in front of a part or towards the front of a structure.
Biomechanics:
the study and application of mechanical laws to living
structures, especially to the musculoskeletal system and locomotion.
Addresses mechanical laws governing structure, function and position
of the human body.
CADCAM:
computer-aided design, computer-aided manufacture.
Cavoid foot:
See
Pes cavus
.
Distal:
away from a point of reference or attachment, usually the trunk
of the body, relative to other parts of the body. Distal interphalangeal
joints are those furthest from the foot.
Dorsiflexed/dorsiflexion:
a 'toe/foot up' motion of the foot at the
ankle which brings the dorsum of the foot closer to the anterior tibia.
Digital dorsiflexion involves moving the toes upwards towards the
dorsum of the foot.
Everted/eversion:
movement in the frontal plane in which the plantar
aspect of the foot is tilted away from the midline of the body.
Flex line:
the part of the orthosis or shoe that corresponds to the
flexion line of the MTP joints.
Frontal plane:
any of the vertical planes passing through the body
perpendicular to the sagittal plane; the plane parallel to the long axis
of the body and at right angles to the median sagittal plane, dividing
the body into front and back portions.
Hallux limitus:
evolving osteoarthritis at the first MTP joint which
results in progressive limitation of motion at the first MTP joint.
Eventually may proceed to a hallux rigidus.
