Introduction. The purpose of this case study was to examine the differences in muscle activation between the right and left sided upper trapezius, middle trapezius, lower trapezius and serratus anterior in a participant with scapular dyskinesis.
Methods. EMG activity was recorded using a Noraxon TeleMyo2400 G2 telemetry unit with a sampling rate of 1 kHz on the aforementioned muscles.
Results. In comparing UE ratios of EMG activity, it appears that the left lower trapezius exerts a significant amount more of energy than the right lower trapezius.
Conclusion. This study may demonstrate the importance of bilateral lower …
