Question 1

In overhead throwing, the late cocking phase places the greatest tensile stress on which structure?

Accepted Answer

Anterior capsule and inferior glenohumeral ligament

Answer

Maximum shoulder external rotation during late cocking produces peak tension in the anterior capsule and IGHL, the primary static restraint to anterior translation.

Question 2

Which biomechanical variable best predicts ACL loading during a single-leg landing task?

Accepted Answer

Peak knee valgus moment

Answer

Peak knee valgus moment during landing has the strongest association with ACL strain and is the primary target of injury-prevention programs.

Question 3

The concept of 'joint centration' refers to:

Accepted Answer

Positioning articular surfaces for optimal congruency and load distribution

Answer

Joint centration (DNS concept) means placing articular surfaces in the position of maximal congruence to distribute load evenly and minimize focal stress.

Question 4

A cyclist presents with anterior knee pain. Raising the saddle height primarily reduces stress on the:

Accepted Answer

Patellar tendon

Answer

Lowering the saddle increases knee flexion angle and patellar tendon load; raising the saddle reduces peak knee flexion and patellar tendon stress.

Question 5

Force closure of the sacroiliac joint is provided by:

Accepted Answer

Muscular and ligamentous compression across the joint

Answer

Force closure refers to active muscular contraction (e.g., biceps femoris, gluteus maximus) and ligament tension that compress the SI joint to enhance stability.
