Question

When applying the hold relax PNF procedure in the presence of a shoulder extension contracture, the target muscles are the:

a) Deltoid and supraspinatus
b) Pectoralis major and latissimus dorsi
c) Teres major and infraspinatus
d) Triceps brachii and rhomboids

Answer 1

When applying hold relax PNF for shoulder extension contracture, the target muscles are the Pectoralis major and latissimus dorsi, as they oppose shoulder extension by medially rotating and adducting the humerus.

Step-by-step explanation:

When applying the hold relax Proprioceptive Neuromuscular Facilitation (PNF) procedure in the presence of a shoulder extension contracture, the target muscles are the muscles that would normally oppose the extension of the shoulder. These would be the muscles primarily responsible for flexing the arm and medially rotating it. Therefore, the correct answer to the question 'When applying the hold relax PNF procedure in the presence of a shoulder extension contracture, the target muscles are the' would be option b) Pectoralis major and latissimus dorsi. The Pectoralis major is known for its role in adducting and medially rotating the humerus, and the latissimus dorsi assists in the extension, adduction, and medially rotating the humerus. Both muscles work in opposition to shoulder extension and would be the focus in a hold relax PNF stretching procedure aiming to resolve a shoulder extension contracture.
