Mechanical methods are among the oldest and most important approaches used for induction of labour (4, 5). They are indicated for labour induction in prolonged pregnancies, diabetic and hypertensive disorders of pregnancy and premature rupture of membranes.
Shoulder Adductor Muscles? What are the muscles involved in shoulder elevation? The muscles involved in elevating the shoulder girdle (e.g. shrugging your shoulders) are the upper fibers of trapezius, levator scapulae, rhomboid major and rhomboid minor.
The deltoid muscle does most of the work in abducting the shoulder, although it's likely that supraspinatus muscle does the first 10-15 degrees of movement.
