Effects of external stabilization on infraspinatus activity and shoulder external rotation strength during the wiper exercise in individuals with and without scapular dyskinesis

Key Points

• This research aims to examine how external stabilization affects infraspinatus muscle activity and shoulder external rotation strength during the wiper exercise.
• Evaluated individuals with and without scapular dyskinesis during the wiper exercise
• Applied external stabilization through the FPT condition
• Measured infraspinatus activity and shoulder external rotation strength
• Improved infraspinatus activity was observed with external stabilization
• Significant enhancement in shoulder external rotation strength was reported
• Benefits were noted in both individuals with and without scapular dyskinesis
