In loco provision of physical therapy services to military firefighters involved in Brumadinho dam disaster.

Objective: To investigate the impact of in loco physical therapy interventions on military firefighters involved in search and rescue operations following the collapse of the Brumadinho dam, in Minas Gerais. To describe the clinical and demographic profile of military firefighters receiving physical therapy care.

Methods: Physical therapy assessment and care protocols were designed.

Applicability of the coactivation method in assessing synergies of the scapular stabilizing muscles.

Hypothesis: This study investigated the feasibility of quantifying the coactivation levels in the evaluation of synergisms of the scapular stabilizing muscles during the elevation and lowering of the arms. This method, which quantifies the overlapping area of the normalized electromyographic (EMG) activity, could be applicable in assessing such muscular synergies.

Materials And Methods: Both shoulders of 10 healthy volunteers were assessed.

Comparisons of electromyographic activity of scapular muscles between elevation and lowering of the arms.

The aim of this study was to compare the electromyographic (EMG) activity levels of the serratus anterior, upper, middle, and lower trapezius muscles between elevation and lowering of the arms with 10 healthy subjects. The EMGs of each muscle was quantified and normalized for the complete movement, as well as for the six different phases of each movement. Repeated measure ANOVAs were used to investigate main and interaction effects between movements/sides and sides/phases (alpha<0.
