Proprioceptive Neuromuscular Facilitation for the Upper Extremity and Scapula: Review and Update on Rehabilitation of Shoulder Pathology.

Proprioceptive Neuromuscular Facilitation (PNF) has deep roots in neurological rehabilitation for the treatment of neuromuscular disorders that has carried over into musculoskeletal rehabilitation and human performance. There are two major aspects of PNF in musculoskeletal practice, stretching and strengthening, but this commentary only addresses the effects of strengthening. Techniques that do not incorporate all the original principles and guidelines as described in the literature are often miscategorized as PNF. The purpose of this clinical update/commentary is to review the essential principles, guidelines, and techniques for the effective utilization of PNF strengthening exercises for the upper extremity highlighting the importance of regaining/maintaining the synergist relationship between the glenohumeral joint and scapula. It will also provide recommended sequencing, exercise parameters, and present evidence of the effectiveness of incorporating PNF patterns into the rehabilitation programs for upper extremity pathologies. # Level of Evidence 5.
