Anterior pelvic tilt is produced by which combined muscular imbalance?
Answer: Tight hip flexors and weak abdominals/gluteals
Anterior pelvic tilt results from tight hip flexors pulling the anterior pelvis down combined with weak abdominals and gluteals that fail to counteract the tilt.
Which term describes the ability of a muscle to return to its original length after being stretched?
Answer: Elasticity
Elasticity is the property that allows a muscle to return to its resting length after passive stretching has been applied.
The thoracolumbar fascia plays a key role in stabilizing which structure during load transfer?
Answer: Lumbar spine and sacroiliac joints
The thoracolumbar fascia connects the latissimus dorsi, gluteus maximus, and transversus abdominis to provide tension that stabilizes the lumbar spine and sacroiliac joints.
Lateral epicondylitis (tennis elbow) involves overuse of which muscle group?
Answer: Wrist extensors
Lateral epicondylitis involves repetitive strain and microtearing of the wrist extensor tendons (primarily ECRB) at their origin on the lateral epicondyle.
When a therapist applies deep tissue pressure, which tissue property allows deformation without returning to original shape?
Answer: Plasticity
Plasticity is the tissue property that allows permanent deformation following applied force, which is relevant to the effects of deep tissue massage on fascia.
The 'force couple' produced by the subscapularis anteriorly and infraspinatus/teres minor posteriorly creates which motion?
Answer: Glenohumeral compression and stabilization
The anterior and posterior rotator cuff muscles create opposing forces that compress and centralize the humeral head in the glenoid fossa, providing dynamic glenohumeral stability.
During normal respiration, which muscle is the primary mover during inhalation?
Answer: Diaphragm
The diaphragm is the primary muscle of inhalation; when it contracts and flattens, it increases thoracic volume, drawing air into the lungs.
