Triceps is maximally efficient with the elbow flexed 20–30°. As the angle of flexion increases, the position of the olecranon approaches the main axis of the humerus which decreases muscle efficiency. In full flexion, however, the triceps tendon is "rolled up" on the olecranon as on a pulley which compensates for the loss of efficiency.
Beighton score criteria: one point for each elbow and knee that hyperextends by 10 degrees or more (4 points), one for each little finger that bends back by 90 degrees (2 points), one for each thumb which can be touched to the forearm (2 points), and one for touching the floor with the palms.
An EDF (elongation, derotation, flexion) cast is a specialized orthopedic device used in the treatment of Infantile Idiopathic Scoliosis. This method of correction was pioneered by UK scoliosis specialist Min Mehta and is a non-surgical approach designed to guide spinal growth and alignment during a critical developmental period. [3]
The sleeping position is the body configuration assumed by a person during or prior to sleeping. Six basic sleeping positions have been identified: [dubious – discuss] Fetus (41%) – curling up in a fetal position. This was the most common position, and is especially popular with women. Log (15%) – lying on one's side with the arms down ...
In anatomy, flexor is a muscle that contracts to perform flexion (from the Latin verb flectere, to bend), [1] a movement that decreases the angle between the bones converging at a joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder , thus decreasing the angle between the upper arm and the forearm .
The humeroulnar joint (ulnohumeral or trochlear joint [1]) is part of the elbow-joint. It is composed of two bones, the humerus and ulna, and is the junction between the trochlear notch of ulna and the trochlea of humerus. [1] It is classified as a simple hinge-joint, which allows for movements of flexion, extension and circumduction.
The position is held as long as possible. The exercise is used to strengthen the quadriceps. Contrary to previous advice in this section, this exercise is NOT good for people with knee problems because the knees bear most of the load, especially when they are held at right angles (90 degrees).

When pronated, the brachioradialis is more active during elbow flexion since the biceps brachii is in a mechanical disadvantage. With the insertion of the muscle so far from the fulcrum of the elbow, the brachioradialis does not generate as much joint torque as the brachialis or the biceps. It is effective mainly when those muscles have already ...
