“…(Fig. 2) The established MDC for lower trapezius mean activity is 7.2-7.9% (Seitz and Uhl, 2012), suggesting current findings are beyond measurement error and clinically meaningful.…”

“…This was not statistically significant or different from a 2.5% MVIC increase observed in the healthy group. Furthermore, changes in mean EMG muscle amplitude between instruction conditions do not exceed the 2% error of the measure (Seitz and Uhl, 2012); thus any subtle trends of inhibition effects are not statistically or clinically meaningful.…”

“…The painful group reported greater pain, less function and less satisfaction with shoulder function than the healthy group (p < 0.001) ( Table 2). Using the within session minimal detectable change (MDC) and standard deviation of lower trapezius EMG mean activity obtained from a pilot study (Seitz and Uhl, 2012), we calculated a sample size of n = 24 total participants would be needed to detect differences in lower trapezius activity that exceed measurement error with 80% power and a = 0.05.…”

Trials four through eight were averaged for each phase separately to represent the participant's mean EMG amplitude under each instruction condition.…”

“…The RMS was averaged in windows of 30°of humerothoracic elevation, from 30°to 120°and expressed as a percentage of peak RMS during MVIC. EMG amplitude of serratus anterior and trapezius muscles normalized by MVIC presents excellent within-day reliability, with standard error of the measure ranging from 1% to 1.7% of MVIC (Seitz and Uhl, 2012).…”

Objective To investigate differences in electromyography (EMG), muscle activity, and scapular kinematics during elevation in the scapular plane between healthy controls, participants with multidirectional shoulder laxity (MDL), and patients with multidirectional shoulder instability (MDI) who are diagnosed with hypermobile Ehlers‐Danlos syndrome (hEDS) or hypermobility spectrum disorder (HSD). Methods Twenty‐seven women with hEDS/HSD and MDI, 27 female healthy control subjects, and 28 female subjects with MDL participated in this study. Scapular 3‐dimensional kinematic data were obtained using 8 Oqus Qualisys cameras. Simultaneously, surface EMG was used to measure muscle activity of the upper, middle, and lower trapezius, infraspinatus, latissimus dorsi, serratus anterior, posterior deltoid, and pectoralis major during arm elevation in the scapular plane. Group differences were assessed using statistical parametric mapping. Results Regarding scapular kinematics, significantly less upward rotation was observed in hEDS/HSD patients with MDI compared to both healthy controls and MDL subjects. Significantly less posterior tilt was seen in hEDS/HSD patients compared to MDL subjects. Furthermore, significantly higher EMG activity of the infraspinatus, middle trapezius, and posterior deltoid was found in hEDS/HSD patients with MDI. Conclusion hEDS/HSD patients with MDI demonstrate altered scapular kinematics and increased EMG muscle activity compared to subjects without MDI. These findings could serve as a stepping stone for future research regarding treatment strategies in patients whose conditions belong to the hypermobility spectrum.
