CCSP - Certified Chiropractic Sports Physician Clinical Biomechanics in Sports Questions and Answers

Question 1

A collegiate baseball pitcher presents with shoulder pain.
A biomechanical analysis reveals that his trunk rotation reaches peak velocity significantly before his pelvis does.
This finding is MOST indicative of a flaw in which biomechanical principle?

Accepted Answer

Kinetic chain sequencing

Answer

Ground reaction force utilization

Answer

Scapulohumeral rhythm

Answer

Glenohumeral joint centration

Question 2

A recreational runner complains of recurrent medial tibial stress syndrome (MTSS). A gait analysis using force plates is most likely to reveal which of the following kinetic characteristics during the stance phase of running?

Accepted Answer

A high vertical instantaneous loading rate (VILR)

Answer

Decreased vertical ground reaction force

Answer

A prolonged supination phase

Answer

Increased braking (anterior-posterior) forces

Question 3

A basketball player sustains a non-contact knee injury while landing from a jump. Video analysis shows a 'valgus collapse' of the knee. This observed movement pattern is MOST commonly associated with an injury to which structure?

Accepted Answer

Anterior cruciate ligament (ACL)

Answer

Posterior cruciate ligament (PCL)

Answer

Lateral collateral ligament (LCL)

Answer

Meniscus (medial or lateral)

Question 4

A tennis player presents with symptoms of lateral epicondylalgia ('tennis elbow'). Biomechanically, this condition is most often aggravated by repetitive eccentric loading of which muscle group during a backhand stroke?

Accepted Answer

Wrist extensors and supinators

Answer

Wrist flexors and pronators

Answer

Digital flexors

Answer

Ulnar and radial deviators

Question 5

Which of the following describes a key biomechanical role of the scapula during overhead throwing to prevent shoulder impingement?

Accepted Answer

Providing a stable base and upwardly rotating to clear the acromial space

Answer

Maintaining a position of downward rotation and protraction

Answer

Maximizing elevation to increase the lever arm of the deltoid

Answer

Limiting posterior tilt to increase rotator cuff activation

Question 6

A gait analysis of a long-distance runner reveals excessive foot pronation at midstance. This biomechanical finding is MOST commonly linked to an increased risk for which of the following conditions?

Accepted Answer

Plantar fasciitis

Answer

Lateral ankle sprains

Answer

Iliotibial (IT) band syndrome

Answer

Stress fractures of the 5th metatarsal
