Read the detailed description
Sub-acromial Impingement Syndrome (SIS) has been identified with a prevalence of almost 40% among shoulder pathologies. SIS has significant economic consequences owing to its treatment costs and losses incurred through workplace absenteeism.
Alterations in scapular muscle performance have been found in subjects with scapular dyskinesis. Hyperactivity of the upper trapezius (UT) with reduced middle (MT) and lower trapezius (LT) muscle activation in addition to insufficient serratus anterior (SA) muscle function have been related to decreased amounts of scapular upward rotation, external rotation, and posterior tilt in patients .
Research into scapular stability exercises for the management of SIS is increasing, yet there is little evidence on their efficacy .
The addition of scapular stabilization exercises to stretching and strengthening exercises can be significantly beneficial in increasing the strength, developing joint position sense and decreasing dyskinesia.
Proprioceptive neuromuscular facilitation (PNF) is a rehabilitation concept which is widely used by physical therapists , promoting motor learning, motor control, strength and mobility . This comprehensive rehabilitation approach includes task-oriented training with manual facilitation aimed at motor learning and motor control .
To the authors' knowledge, none of the studies has investigated the potential effect abnormal scapular muscle strengthening versus PNF exercise on the muscle strenth, muscle ratio, and ROM of the scapula during arm elevation in patient with SIS.

Questions about this trial
What is this clinical trial studying?
A study testing exercises in people with Shoulder Impingement, run by Cairo University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: paused, as of the sponsor's last update on 10 Sep 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
muscle strength for scapular muscles by Lafayette hand held dynamometer (time frame: baseline). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05535699, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Sep 2022; AzTrials last refreshed its copy on 1 Nov 2026.
