ART Biomechanics & Functional Movement 3 — Questions and Answers
Question 1: The 'cumulative injury cycle' in ART theory begins with which initial event?
- Inflammation
- Tissue tension or pressure (Correct answer)
- Fibrosis formation
- Decreased circulation
Correct answer: Tissue tension or pressure
The cumulative injury cycle starts with acute or repetitive tension/pressure on tissue, leading to inflammation, reduced oxygenation, fibrosis, and progressive adhesion formation.
Question 2: During an overhead press, which scapular movement is required to maintain optimal glenohumeral rhythm and rotator cuff clearance?
- Scapular depression and downward rotation
- Scapular elevation and upward rotation (Correct answer)
- Scapular retraction and anterior tilt
- Scapular protraction and downward rotation
Correct answer: Scapular elevation and upward rotation
Upward rotation and posterior tilt of the scapula are essential during overhead motion to maintain subacromial space and allow full glenohumeral elevation.
Question 3: What does the term 'tissue texture abnormality' mean in the context of ART assessment?
- Visible bruising of superficial skin
- Palpable change in the quality, tension, or resilience of soft tissue (Correct answer)
- Patient-reported burning sensation during palpation
- Radiographic evidence of calcification within muscle
Correct answer: Palpable change in the quality, tension, or resilience of soft tissue
Tissue texture abnormality refers to palpable findings such as increased density, ropiness, or altered tension compared to normal tissue, used to identify fibrotic restrictions.
Question 4: Which of the following best describes the role of the thoracolumbar fascia in force transfer during lifting?
- It restricts lumbar extension by limiting erector spinae contraction
- It transmits tensile loads between the lower extremities and upper extremities via interconnected layers (Correct answer)
- It provides compressive support to the intervertebral discs
- It stores elastic energy in the hip flexors during the descent phase
Correct answer: It transmits tensile loads between the lower extremities and upper extremities via interconnected layers
The thoracolumbar fascia connects latissimus dorsi, gluteus maximus, and contralateral muscle chains, serving as a key tensional link for load transfer during heavy lifting.
Question 5: In ART nerve entrapment protocols, which direction of tissue motion is applied relative to the nerve being treated?
- Perpendicular to the nerve's longitudinal axis (Correct answer)
- Parallel to the nerve, in the direction of least resistance
- Distal-to-proximal along the nerve's pathway
- Away from the nerve's anatomical pathway
Correct answer: Perpendicular to the nerve's longitudinal axis
ART nerve entrapment protocols apply cross-fiber tension perpendicular to the nerve's pathway to release adhesions between the nerve and surrounding tissue.
Question 6: A patient presents with limited shoulder internal rotation and posterior shoulder tightness. Which ART target would most directly address this restriction?
- Pectoralis minor and coracobrachialis
- Posterior capsule and external rotators (infraspinatus, teres minor) (Correct answer)
- Subscapularis and anterior deltoid
- Serratus anterior and rhomboids
Correct answer: Posterior capsule and external rotators (infraspinatus, teres minor)
Posterior shoulder tightness limiting internal rotation most commonly involves adhesions in the infraspinatus, teres minor, and posterior capsule, which are the primary ART targets.
Question 7: Which kinematic event during running gait is most associated with increased patellofemoral joint stress?
- Heel strike with the knee fully extended
- Contralateral pelvic drop combined with ipsilateral knee valgus at midstance (Correct answer)
- Toe-off with excessive plantarflexion
- Initial swing phase hip flexion beyond 70 degrees
Correct answer: Contralateral pelvic drop combined with ipsilateral knee valgus at midstance
Contralateral pelvic drop drives ipsilateral hip adduction and knee valgus at midstance, increasing the Q-angle and lateral patellofemoral compression forces.
