Proprioceptive Neuromuscular Facilitation (PNF) include significantly boosting flexibility, strength, and neuromuscular control, easing pain, and restoring functional movement for daily tasks and sports by using diagonal patterns and muscle contractions to improve range of motion (ROM) and muscle coordination, making it great for shoulder rehab. PNF helps the brain-muscle connection, reduces muscle tension, and builds functional strength for better joint stability and movement patterns, accordin
