The authors studied the trapezius (pars media) and rhomboideus major muscles in movements of flexion, extension, inclination and rotation of the head. The electromyographic records demonstrated that referred muscles are ...

The authors studied the trapezius (pars media) and rhomboideus major muscles during deep inspiration and expiration. The electromyographic records demonstrated that these muscles showed no activity in either phase of breathing.

The authors studied the trapezius (middle portion) and rhomboideus major muscles in movements of flexion, extension, inclination and rotation of the trunk. The electromyographic records demonstrate that such muscles show ...

The participation of the trapezius (middle portion) and rhomboideus major muscles submitted to an isometric tension (holding downward dumbells of 11, 15 and 19 kg) was analysed in 40 young adult male vounteers. A 2 channel ...

The electromyographic study of the trapezius (pars superior) and levator scapulae mm. in the head movements was carried out in 30 young, adult male volunteers of both sexes and with no antecedent muscular or articular ...

The participation of the trapezius (pars media) and rhomboideus major muscles were studied electromyographically in movements of lateral and medial rotation (free and against resistance) of the arm. In the majority of cases ...

The participation of the trapezius (pars media) and rhomboideus major muscles in free movements of abduction, adduction, flexion, extension and hyperextension of the arm was studied electromyographically. These muscles ...
