What plane of motion is scapular elevation?
Movement of the Scapula Four movements of the scapula occur in the frontal plane: elevation – associated with reaching when glenohumeral abduction and flexion are limited in range. depression – associated as a closed-chain motion with crutch walking, transfers, and use of a walker.
How many planes does the scapula move in?
three planes
The scapula has five degrees of freedom for movement on the thorax: It can move in two “straight-line” directions or “translations.” It can move in three planes, around three different axes.
What plane of movement is scapular protraction?
horizontal plane rotations
Protraction is a summation of horizontal plane rotations at both the SC and AC joints. These are translatory motions of the scapula away from or toward the vertebral column, respectively.
What plane is scapular abduction?
Conclusions: Abduction can be performed within a 30° arc of the scapular plane with no change in shoulder muscle activation patterns. Only middle deltoid activation levels change between the scapular and coronal planes and middle deltoid and upper trapezius between the scapular and scapular +30° planes.
What is the plane of the scapula?
The normal resting position of scapular as it lies on the posterior rib cage is at an angle of 30 to 45 degrees. Raising the arm 30 to 45 degrees from the coronal plane is called the scapular plane.
What plane is scapular adduction?
The scapula moves around a dorso-ventral axis, resulting in a rotation in the frontal plane.
What plane is shoulder flexion in?
Sagittal
Summary
| Plane | Description |
|---|---|
| Sagittal / Antero-posterior | Bisects the body from front to back, dividing it into left and right halves. Flexion and Extension movements usually occur in this plane. |
What plane is internal rotation of the shoulder?
transverse plane
The shoulder joint is an example of a multiplanar/triaxial joint. It allows forward and backward movement in the sagittal plane, lateral, or side-to-side movement, in the frontal plane, and internal and external rotation in the transverse plane.
Does the scapula move during shoulder flexion?
During shoulder flexion, the scapula should: upwardly rotate, posteriorly tilt, and externally rotate slightly at end range.
Which of the following muscles moves the scapula?
The trapezius is a large flat muscle that covers much of the upper back. Its fibers extend in several directions, and it elevates, retracts, and rotates the scapula freely. The rhomboideus and the levator scapulae muscles also retract and elevate the scapula.
What is upward and downward rotation of the scapula?
This is also called upward rotation of the glenoid fossa, and it is an essential motion for completing abduction of the arm. Muscles: trapezius and serratus anterior are synergists. When the arm is fully abducted, downward rotation of the scapula (or glenoid fossa) occurs first in adduction of the arm.
What movements occur in sagittal plane?
Sagittal plane motion would include forward and backward motions, like sit-ups, back extensions or biceps curls. The sagittal plane cuts through the center of the body, so the motion is front to back or back to front, including straight forward running.
What plane is flexion and extension?
Which muscles upwardly rotate the scapula?
The trapezius muscle adducts and upwardly (laterally) rotates the scapula.
What drives upward rotation of the scapula?
– Function: fixes the scapula into the thoracic wall, and aids in rotation and abduction of the arm (90 to 180 degrees) – Origin: Surface of the upper eight ribs at the side of the chest – Insertion: Along the entire anterior length of the medial border of the scapula – Innervation: Long thoracic nerve (C5, C6, C7)
What muscle rotates the scapula?
Scapula does not achieve 60˚ of upward rotation; correction decreases symptoms
What are the movements of the scapula?
Elevation: movement that allows the shoulder girdle to move upwards as in shrugging the shoulders.
