Sports Med 2 Proprioceptive Neuromuscular Facilitation First used by physical therapists for treating patients who had various types of neuromuscular paralysis • Now used as a stretching technique to increase flexibility Stretching techniques that involve combinations of alternating contractions and stretches Used in rehabilitation to facilitate strength and increase ROM ADVANTAGES Increase muscular flexibility Increase ROM DISADVANTAGES Exercises require a partner Exercises require expertise •PNF involves 3 types of Movements •Flexion/Extension •Abduction/Adduction •Internal/External Rotation Passive • The degree to which a joint may be passively moved to the endpoints in the ROM • No muscular contraction is involved Active • The degree to which a joint can be moved by a muscle contraction Isometric • Means to contract a muscle statically without changing its length • This contraction is referred to has “hold” Concentric • The muscle shortens while contracting against resistance • This contraction is referred to as “contract” Passive stretches • Referred to as “relax” Hold-relax • Passive stretch – for 10 sec. • Athlete is instructed to “hold and not let leg move” for 6 seconds Athlete resists movement which creates isometric contraction • Athlete relaxes • Passive stretch held for 10 sec. • Repeat 3 times Contract-relax • • • • • Passive stretch –hold for 10 sec Athlete isotonically pushes against resistance from partner-6 sec Athlete relaxes Passive stretch applied and held for 10 sec. Repeat 3 times • • • • Athlete moves body part to point of resistance and is told to “hold” Muscles are isometrically resisted by partner for 6 sec. Athlete relaxesAthlete moves body part into farther ROM- stretch 10 secs hold-relax- with contraction
