Question 1

A swimmer presents with impingement symptoms and weakness in external rotation. Which muscle is MOST critical to address for restoring dynamic glenohumeral stability?

Accepted Answer

Infraspinatus and teres minor

Answer

Infraspinatus and teres minor provide the primary external rotation force couple and posterior rotator cuff depression necessary for dynamic glenohumeral stability during overhead motions.

Question 2

When performing a drop vertical jump screen, a female athlete demonstrates a valgus collapse greater than 10° at initial contact. Which combination of strength deficits MOST likely contributes to this pattern?

Accepted Answer

Weak hip abductors, external rotators, and knee extensors

Answer

Dynamic valgus during landing is primarily driven by weakness of hip abductors, external rotators, and insufficient eccentric knee extensor control.

Question 3

A collegiate pitcher reports progressive posterior shoulder tightness and loss of internal rotation. GIRD (glenohumeral internal rotation deficit) is noted at 25°. What is the FIRST intervention priority?

Accepted Answer

Perform posterior capsule and posterior rotator cuff stretching (sleeper stretch)

Answer

GIRD is primarily managed with posterior capsule stretching such as the sleeper stretch to restore internal rotation range and reduce impingement risk.

Question 4

Which concept describes the accumulation of subclinical tissue damage exceeding the tissue's capacity to recover between training sessions, ultimately resulting in overuse injury?

Accepted Answer

Acute:chronic workload ratio imbalance

Answer

An elevated acute:chronic workload ratio (>1.5) indicates recent training load spikes that exceed the tissue's prepared capacity, directly linking load management to overuse injury risk.

Question 5

A football linebacker presents with a Grade II medial collateral ligament sprain. At 3 weeks post-injury, which criterion is MOST important before initiating sport-specific agility training?

Accepted Answer

Absence of effusion and full pain-free ROM with valgus stress test negative

Answer

Before agility training after MCL sprain, the clinician must confirm absent effusion, full pain-free ROM, and a negative valgus stress test indicating adequate ligament healing.
