The primary purpose was to determine if there is a difference between the median frequency slopes of 5 posterior shoulder muscles during the initial portion of the Posterior Shoulder Endurance Test (PSET) at the 90⁰ and 135⁰ shoulder abduction positions.
Fifty-five healthy volunteers (31 females) participated. The median frequency of the posterior deltoid (PD), upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and infraspinatus (INF) was measured during the PSET at 90⁰ and 135⁰ of shoulder abduction. External torque of 13±1 Nm was used for females and 21±1 Nm for males. A fixed effect multi-variable regression model was used …
