The active recording surface electrode was placed over the anterior fibers of the deltoid muscle 3-4 cm beneath the anterior margin of the acromion
This is due to powerful contraction of the muscles around the shoulder forcing the humeral head superiorly and posteriorly against the acromion
, and medially against the glenoid before it slips behind the glenoid rim into posterior dislocation.
Rotator cuff muscles traverse a narrow space between the acromion
and coracoacromial, ligament above and the humeral head below.
4) The therapist must determine the proper cuff size by determining the circumference of the arm at the half-way point between the olecranon and the acromion
The capture electrodes were positioned at the midpoint between the spinous process of the C7 vertebra and the acromion
bilaterally according to SENIAM criteria.
Mid-arm circumference (cm) was measured at the level of mid-arm taking acromion
process and olecranon as reference points.
TSF was measured with Holtain skinfold caliper and MAC was measured in the nondominant arm, from the posterior of the midpoint between acromion
and olecranon, with a measuring tape.
During shoulder flexion, the supraspinatus tendon and bursa become entrapped between the anteroinferior aspect of the acromion
(and coracoacromial ligament) and the greater tuberosity of the humerus.
The measurement was taken at the mid-point between the top of the acromion
process of the scapula and the olecranon process of the ulna and was measured with the arm hanging freely at the subject's side.
The stationary arm was placed along the lateral midline of the humerus in line with the acromion
process, and the moving arm was placed along the lateral midline of the radius in line with the radial styloid process.
Mid-arm circumference (MAC) was measured using a steel, metric tape measure (KDS, Tokyo, Japan) midway between the tip of the acromion
and the olecranon, and was recorded to the nearest 0.
Biceps and triceps thicknesses were measured at the midpoint of the upper arm, between the acromion
process and the tip of the bent elbow.
Sitting ability was measured as the maximum reach distance, using the intact arm, in three directions: forward, ipislateral (45 degrees from the intact acromion
away from the intact side), and across (45 degrees from the intact acromion
across the body toward affected side).
: (a-KRO-mee-on) The point of your shoulder, the outer, upper part of your shoulder blade, is called the acromion
On radiographs, the distal end of the clavicle is displaced above the superior border of the acromion
