PNF/Fascilitated Stretching – Simple Solution to Chronic Tight Hamstrings!
Proprioceptive neuromuscular facilitation (PNF) stretching techniques are commonly used in the athletic and clinical environments to enhance both active and passive range of motion (ROM) with a view to optimizing motor performance and rehabilitation. PNF stretching is positioned in the literature as the most effective stretching technique when the aim is to increase ROM, particularly in respect to short-term changes in ROM.
McCarthy et al. demonstrated that ROM gains last for approximately 7 days after 1 week of twice-daily stretching
12-week period in the direction of long-lever hip flexion when conducting one repetition of PNF stretching 2 times per week
