During normal gait, which phase of the gait cycle requires the greatest quadriceps activity?
Answer: Loading response (early stance)
The loading response (initial 0-12% of gait cycle) demands peak quadriceps activity to control knee flexion and accept body weight during weight acceptance.
The carrying angle of the elbow is formed between which two bones?
Answer: Humerus and ulna
The carrying angle is the valgus angle formed between the long axis of the humerus and the long axis of the ulna when the elbow is fully extended and the forearm supinated. Normal values are 5-15 degrees in men and 10-25 degrees in women.
The screw-home mechanism of the knee occurs during the last degrees of extension and involves which rotation?
Answer: Lateral rotation of the femur on the tibia
The screw-home mechanism involves lateral rotation of the femur (or medial rotation of the tibia in open kinetic chain) during the last 30 degrees of knee extension, locking the knee for weight-bearing.
Which rotator cuff muscle is most likely to be torn in a classic degenerative rotator cuff injury?
Answer: Supraspinatus
The supraspinatus is most commonly torn, often at its critical zone — a relatively avascular area approximately 1 cm proximal to its insertion on the greater tuberosity.
In the spine, which ligament runs within the vertebral canal on the posterior surface of the vertebral bodies?
Answer: Posterior longitudinal ligament
The posterior longitudinal ligament runs along the posterior surface of the vertebral bodies inside the vertebral canal, resisting spinal flexion and posterior disc herniation.
Which of the following describes the concave-convex rule for joint mobilization?
Answer: A concave surface glides in the same direction as bone movement; a convex surface glides opposite
Per Kaltenborn's concave-convex rule: when a concave surface moves on a convex surface, glide and roll occur in the same direction. When a convex surface moves on a concave surface, glide occurs opposite to roll and bone movement.
