Context: With a key role in normal shoulder function, scapular kinematics have been investigated in shoulder impingement syndrome (SIS). Objectives: This systematic review aimed at determining scapular kinematic patterns in patients with SIS compared to in asymptomatic individuals. Data Sources: Databases such as PubMed, Scopus, Web of Science, Ovid, Embase and PEDRO were searched from January 1995 to June 2021. Study Selection: Articles in English published in peer-reviewed journals and using motion analysis systems to compare scapular kinematics between patients with SIS and asymptomatic subjects during arm elevation were included. Data Extraction: A modified Downs and Black checklist was used to assess the risk of bias of the included studies. A random-effects model was employed to perform a meta-analysis. Results: Nine out of 1650 screened abstracts were included for data extraction. Scapular upward rotation significantly decreased during arm elevation in SIS (SMD = -0.13, 95% C...

Context Impaired scapular kinematics are commonly reported in patients with subacromial impingement syndrome (SIS). Various therapeutic interventions designed to improve scapular kinematics and minimize pain and disability have been described in the literature. However, the short- and long-term benefits of these interventions are unclear. Objective To determine the effects of specific short- and long-term therapeutic interventions on scapular kinematics and disability in patients with SIS. Data Sources We searched PubMed, CINAHL, and SPORTDiscus databases from their origins to January 2018 using a combination of the key words scapular kinematics AND (shoulder dysfunction OR subacromial impingement) and conducted a manual search by reviewing the references of the identified papers. Study Selection Studies were included if (1) preintervention and postintervention measures were available; (2) patient-reported outcomes were reported; (3) scapular kinematics measures at 90° of ascending ...
The Prediction of Disability to Scapular Training in Patients with Shoulder Impingement Syndrome
Egyptian Journal of Applied Science, 2021
Study design: prospective clinical trial study Background: People with shoulder impingement syndrome (SIS) present alterations in the scapular kinematics 'scapular dyskinesis' when compared with asymptomatic individuals. Those patients consistently report disability, especially during overhead activities, which might hinder activities of daily living and for some sports movements. Objectives: To investigate if the disability can predict patient's response to scapular training. Methods: Forty-five patients between 18-45 years old, their mean age (32.56±2.85) years and their mean body mass index (BMI) (29±6) kg/m², suffering from subacromial impingement syndrome assessed by Shoulder Pain and Disability Index (SPADI) before and after exercise program of scapular muscle training (Cools exercises), serratus anterior strength (supine punch) and scapular stabilization exercises for one month. Results: The Area under curve (AUC) showed excellent results with disability percent 0.94(sensitivity 0.956, specificity 0.156). Conclusion: disability is a predictor of treatment success in patients suffering from subacromial impingement syndrome treated with scapular training.
Shoulder proprioception in patients with subacromial impingement syndrome
Journal of Back and Musculoskeletal Rehabilitation, 2017
BACKGROUND: Recently, proprioception deficits of the rotator cuff and the deltoid muscles have been suggested to play a pivotal role in the subacromial impingement syndrome (SIS). To date, there are no study has been found where the kinesthesia and joint position senses have been evaluated together in SIS. OBJECTIVE: To investigate the shoulder proprioception in patients with SIS. METHODS: Sixty-one patients with SIS and 30 healthy controls, aging between 25 and 65 years, were included in the study. Main outcome measure was proprioception, assessed with an isokinetic dynamometer. Kinesthesia, active and passive joint repositioning senses were tested at 0 • and 10 • external rotation. All tests were repeated 4 times and the mean of angular errors were obtained. RESULTS: The mean age was 49.14 ± 10.27 and 48.80 ± 11.09 years in patient group and in control group respectively. No significant difference was found between two groups in terms of age, gender and dominance. When involved and uninvolved shoulders of the patient group were compared, kinesthesia, active and passive joint position senses were significantly impaired in involved shoulders at all angles (P < 0.05). When involved shoulders of the patient group were compared to the control group, kinesthesia, active and passive joint position senses were significantly impaired in involved shoulders in patient group at all angles (P < 0.05) except active position sense at 0 •. When uninvolved shoulders of the patient group were compared to the control group, kinesthesia at 10 • was significantly impaired (P < 0.05). CONCLUSION: This study showed that shoulder proprioception was impaired in patients with SIS. This proprioceptive impairment was found not only in involved shoulders but also in uninvolved shoulders in patients with SIS.

To investigate the effects of 2 different exercise programs on 3-dimensional scapular kinematics, disability, and pain in participants with subacromial impingement syndrome (SIS). Design: Randomized controlled trial. Setting: Outpatient clinic and research laboratory. Participants: Participants who were diagnosed with SIS and who also exhibited scapular dyskinesis (NZ30). Interventions: The participants were randomized in 2 different exercise groups: (1) shoulder girdle stretching and strengthening with additional scapular stabilization exercises based on a kinetic chain approach (intervention group), and (2) shoulder girdle stretching and strengthening exercises only (control group). Main Outcome Measures: Three-dimensional scapular kinematics, self-reported shoulder pain, and disability were evaluated at baseline, after 6 weeks of training, and after 12 weeks of training. Results: Significant differences were observed between the control and intervention groups in external rotation and posterior tilt after 6 weeks of training and in external rotation, posterior tilt, and upward rotation after 12 weeks of training. All groups showed improvement in self-reported pain and disability scores; however, there were no significant differences between the groups. Conclusions: Progressive exercise training independent from specific scapular stabilization exercises provides decreased disability and pain severity in impingement syndrome.
