The study compared the effects on Proprioceptive Neuromuscular Facilitation (PNF) activities with shoulder mobilization (SM) in addition to traditional physiotherapy on patients with Subacromial Impingement Syndrome's discomfort, range of motion (ROM), functioning, and muscle strength (SIS).
What is Proprioceptive Neuromuscular Facilitation (PNF)?You can increase your range of motion by using the stretching technique known as proprioceptive neuromuscular facilitation (PNF). After an accident or surgery, PNF is frequently used by therapists to assist patients restore their range of motion. Athletes and dancers can also utilize it to increase their flexibility.
Methods for doing this are-
In three groups of forty-four patients each, traditional physiotherapy (control group; n = 14), traditional physiotherapy plus PNF activities (PNF group; n = 15), plus conventional physiotherapy plus SM procedures (SM group; n = 15), conventional physiotherapy was randomly assigned to. The VAS (Visual Analog Scale), goniometer, push-pull dynamometer, Steady score, and DASH (Disabilities of the Arm, Shoulder, and Hand) score were used to assess pain, range of motion (ROM), muscular strength, and functionality. 20 sessions (four weeks) of therapy were provided to the patients. At the baseline, weeks 2, four, and sixteen, assessments were made.Therefore, patients with SIS may benefit better from PNF or SM in addition to traditional physiotherapy in terms of pain relief and functional improvement.
To sustain the ROM increase obtained with SIS therapy after treatment, it is advised to add SM and PNF to traditional treatment. This treatment should also be used for 4 weeks to build muscular strength.
