To compare the effect between the exercise intervention (strengthening exercise and stretching exercise) and exercise intervention with taping on decreasing round shoulder posture and improving symptoms in subjects with shoulder impingement syndrome/round shoulder syndrome.

Background: Poor posture and abnormal scapular kinematics have been suggested as possible primary factors in developing Shoulder impingement syndrome (SIS) and also as secondary observed phenomena of SIS. Round shoulder posture (RSP) is major and common posture contributing to increase the potential for subacromial impingement or exaggerate the symptoms of SIS. Objective: To compare the effect between the exercise intervention (strengthening exercise and stretching exercise) and exercise intervention with taping on decreasing RSP and improving symptoms in subjects with SIS/RSP. Methods: Forty subjects with impingement age between 20 and 75 are recruited and measured on acromial distance, pectoralis minor index (PMI), posterior and anterior shoulder tightness, distance of scapular medial border, pain score and flexilevel scale of shoulder function (FLEX-SF). Clinical significance: Shoulder impingement syndrome (SIS) have been identified as the majority of reported shoulder complaints. The project will provide an effective intervention for subjects with SIS/RSP.
