HIPS Don't Lie
The motions of the hip that occurs about the anterior-posterior axis of rotation.
What is ABDUCTION & ADDUCTION?
The bone that increases the internal moment arm of the quadriceps, enhancing knee extension torque.
What is the PATELLA?
The primary motions that occur at the talocrural joint.
What is DORSIFLEXION and PLANTAR FLEXION?
The phase of gait that constitutes the last 40% of the gait cycle.
What is the SWING PHASE?
The measurement of an individual's torque production.
What is STRENGTH?
The abnormal response where the opposite side of the pelvis drops excessively under the force of gravity due to hip abductor muscle weakness.
What is a positive TRENDELENBURG SIGN?
The function of this ligament is to resist a posterior translation of the tibia relative to a fixed femur.
What is the POSTERIOR CRUCIATE LIGAMENT?
The joint that is commonly referred to as a "mortise joint."
What is the TALOCRURAL JOINT?
The event that follows the mid stance period of a gait cycle.
What is HEEL OFF?
The basic contractile unit of muscle fiber.
What is a SARCOMERE?
Short-arc, pelvic-on-femoral hip flexion with trunk remaining essentially upright
What is ANTERIOR PELVIC TILT?
Semimembranosus, Semitendinosus, Biceps femoris-long and short heads, Gracilis and sartorius, gastrocnemius and plantaris, popliteus
What are KNEE FLEXOR MUSCLES?
The nerve that innervates most of the muscles that dorsiflex the foot.
What is the DEEP PERONEAL NERVE?
The events that take place between successive heel contacts of the same foot.
What is STRIDE?
A type of joint composed of the articulation between a large, rounded, convex member and a relatively shallow concave member. The tibiofemoral joint, for example.
What is a CONDYLOID JOINT?
The nerve that largely innervates the hip adductor muscles.
What is the OBTURATOR NERVE?
The primary ligament involved in resisting large valgus-producing forces at the knee.
What is MEDIAL COLLATERAL LIGAMENT?
The predicted motion produced by a muscle that courses on the medial side of the anterior-posterior axis of rotation.
What is EVERSION?
A gait deviation comprised of excessive hyperextension of the knee during stance phase of gait.
What is GENU RECURVATUM?
Uses the principles of a branch of physics that involves the analysis of the actions of the actions with the goal of improving performance, prevent injury, and aid rehab.
What is BIOMECHANICS?
The frontal plane angle created between the femoral neck and the shaft of femur (Hint: optimal hip alignment).
This automatic rotation of the tibia and the femur that assists in locking the knee.
What is the SCREW-HOME MECHANISM?
The combined action of dorsiflexion, eversion, and abduction of the ankle and foot.
What is PRONATION?
A gait pattern caused by weak hip extensors and overly strong (and spastic) hip flexor muscles.
What is CROUCHED GAIT?
The anterior displacement of one vertebra over another, often occurring at the L5-S1 junction.
What is anterior SPONDYLOLISTHESIS?
