Background Scapular dyskinesia is a common condition in chronic shoulder pain. Alterations in scapular muscle activity are associated with scapular dyskinesia. PhysioPlux is created for rehabilitation in physical therapy. It is an interactive training system, using electromyography in training to restore the muscle activity around the scapula. Objective The aim of this research is to evaluate if a consistent shoulder muscle activation pattern exist in asymptomatic shoulders during bilateral arm elevation. A reference database should be established for future comparison with symptomatic shoulders in order to use the PhysioPlux system in an evaluative protocol, besides a training protocol. Methods All participants (n=52, age = 55.2 � 5.59) were instructed to actively perform ante exion in the sagittal plane, abduction in frontal and scapular plane. Primary outcome measures were onset activation time in milliseconds. Results A large amount of variance was present in and between shoulders, in both categorical and numerical data. Categorical di�erences in the shoulders are shown by the possible sequences and their appearance in each plane and each shoulder. Di�erences between shoulders were measured using the Chi2 test, p-values ranged from 0.001-0.022. The variation in numerical data for each shoulder and each plane where shown using box plots. Conclusion There is not a consistent activation pattern in and between shoulders using muscle onset activation, using PhysioPlux. Although this system is very effective in therapeutic exercise, using real time visual myofeedback, to use this system for evaluative purposes in scapula dyskinesia, more information is needed such as duration and amount of muscle activity.
