1. Why was the L-code established? - a. To develop a unified method of describing products/services to payers What is a common compensation for poor flexion of the socket in a TF amputee? - Hyperlordosis If a TF amputee tends to externally "smear" their foot in stance while abducting their prosthesis, what could be a probable cause and WHY? - If inadequate flexion is built into the TF socket the patient will develop gait deviations utilizing compensatory motions for forward progression. Inadequate flexion of the socket will cause compensatory hyperlordosis, causing discomfort for the patient over time. Ehlers-danlos syndrome - A group of inherited disorders that affect your connective tissues — primarily your skin, joints and blood vessel walls. People who have this syndrome usually have overly flexible joints and stretchy, fragile skin. This can become a problem if you have a wound that requires stitches, because the skin often isn't strong enough to hold them. Hydrocephalus accompanies what generally? - Spina Bifida What muscle most closely duplicates tibialis anterior? - Extensor Digitorum Longus What is often the result of an irregular birth? - Erb's Palsy Erb's Palsy - Caused by excessive stretching of the shoulder, tearing of uppermost roots C5 and C6 (sometimes C7 or superior trunk of brachial plexus. Paralyzes deltoid, supraspinatus, biceps brachii and supinator muscles. (arms) Often occurs at birth Meningitis - inflammation of the outer covering of the brain and spinal cord Pleuritis - inflammation of the pleura (also called pleurisy) Left posterior plagio - Bossing of the right posterior cranium and flattening of the left posterior cranium positional plagiocephaly - flattening of the occiput and prominence of ipsilateral frontal area brachycephaly - fetal head is elongated in the transverse diameter and shortened in the anteroposterior diameter. What pathology is most likely to be fit with free knee joints? - Genu Varum Deformity nonstructural scoliosis - a reversible lateral curvature of spine WITHOUT a rotational component and straightening as individual flexes spine resolves when the patient bends to the affected side Most likely the result of a LLD What ligament prevents hyperextension of the hip joint? - Iliofemoral ligament Central Cord Syndrome - UE deficits -to find your center on a balance beams, you have to use your UEs often due to HE injury Anterior cord syndrome - - caused by flexion injuries - occurs when 2/3 of the anterior cord is lost - *motor function, pain, and temperature sensation lost bilaterally below the lesion* (*flaccidity* below the lesion) Brown-Sequard Syndrome - Hemi-section of the cord - ipsilateral (same side) loss of motor, proprioception, vibration, amd deep touch - contralateral (opposite side) loss of pain and thermal sense Posterior Cord Syndrome - Loss of dorsal columns bilaterally, bilateral loss of proprioception, vibration, pressure, stereognosis, 2 point discrimination; preservation of motor function, pain and light touch; very rare!

Why? - WHO with Thumb Post Incorporating the wrist allows for the user to have more stability A primary elbow flexor - brachialis Main function of brachioradialis - elbow flexion
