Objective To determine the effectiveness of scapular proprioceptive
neuromuscular facilitation (PNF) techniques in patients with subacromial
impingement syndrome (SIS).
Methods 36 patients were randomized and a 6-week exercise program was
applied to both groups 2 days a week. PNF group also received rhythmic
initiation and repeated stretch PNF techniques in 2 scapula diagonals. Pain and
function were primary outcomes. Active range of motion (ROM), pain pressure
threshold (PPT), active myofascial trigger points (MTrPs), scapular dyskinesis,
anxiety and depression status were secondary outcomes.
Results The improvement in function, internal rotation ROM, PPT, active
MTrPs and patient satisfaction was significantly greater in PNF group than
exercise group (p<0.05). Scapular dyskinesis improved only in PNF group
(p<0.05). Significant improvement in pain, function, ROM, PPT, active
MTrPs, anxiety and depression was found in both groups (p<0.05).
Conclusions Both scapular PNF techniques and standard exercise program are
effective in the treatment of SIS. However, scapular PNF techniques can be added
to the exercise program to further improve function, ROM, PPT, active MTrPs,
scapular dyskinesis, and patient satisfaction.
