Possible such causes include shortening of the hamstrings or genuine anatomic leg lengthening or shortening buy 400 mg hoodia amex herbs collision. Procedure: The patient is supine with the painful side as close as possible to the edge of the examining table or projecting beyond it purchase 400 mg hoodia overnight delivery worldwide herbals. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. The examiner then passively hyperextends the leg next to the edge of the examining table. This is done with the patient lying on his or her normal side with that leg flexed at the hip and knee. The examiner then passively hyperextends the other leg (the one not in contact with the table). Assessment: If there is dysfunction in the sacroiliac joint, hyperexten- sion of the leg will lead to motion in the sacroiliac joint, causing pain or exacerbation of existing pain. The examiner places both hands on the ilium of the affected side and exerts downward pressure on the pelvis. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. This is done with patient lying on his or her right side and immobilizing that leg, flexed at the hip and knee, with both hands. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. The exam- iner raises the flexed leg off the examining table, hyperextending the hip. Assessment: The first part of this test initially places stress on the posterior structures of the sacroiliac joint; later the stress shifts to the anterior portions, primarily affecting the anterior sacroiliac ligaments. Pain in the lumbar spine suggests the presence of pathologic processes at that site. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. Pain within the hip suggests degen- erative joint disease, hip dysplasia, or contracture of the iliopsoas. Pain felt posteriorly in the sacroiliac joint suggests a disease process at that site. Sacroiliac Stress Test Demonstrates involvement of the anterior sacroiliac ligaments in a sacroiliac joint syndrome. By crossing his or her hands, the examiner adds a lateral force vector to the compression. The antero- posterior direction of the compressive load on the pelvis places stress on the posterior portions of the sacroiliac joint, whereas the lateral com- ponent places stress on the anterior sacroiliac ligaments. Assessment: Deep pain is a sign of strained anterior sacroiliac liga- ments on the side of the pain (sacrospinal and sacrotuberal ligaments). Pain in the buttocks can be produced by compression from the examin- ing table or by irritation of the posterior portions of the sacroiliac joint. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. This test is nor- mally performed to evaluate insuf• ciency of the gluteus medius and gluteus minimus. Assessment: Increasing pain in the affected sacroiliac joint is a sign of sacroiliac irritation. Patients with hip disorders may also feel increased pain when this test is performed. If the patient is unable to abduct the leg or can only do so slightly, but does not report any pain, this suggests insuf• - ciency of the gluteus medius. Nerve Root Compression Syndrome Disk extrusions usually lead to muscular compression syndromes with radicular pain.

Typical signs of compression include nighttime paresthesia and bra- chialgia purchase 400mg hoodia free shipping herbs for depression, morning stiffness cheap 400 mg hoodia fast delivery himalaya herbals 52, and sensory and motor deficits in the region supplied by the median nerve (atrophy of the thenar musculature). Electromyography and measurement of nerve conduction velocity by electroneurography are important studies in diagnosing carpal tunnel syndrome. Cubital Tunnel Syndrome The ulnar nerve courses through a bony groove posterior to the medial epicondyle. Injury, traction, inflammation, scarring, or chronic compression are the most common causes of damage to the ulnar nerve. Sensory deficits (numbness in the little finger) and motor deficits in the area supplied by the ulnar nerve are typical findings in the presence of a nerve lesion. Electromyography and sensory electroneurography can determine the location of the compression neuropathy. Tests of Motor Function in the Hand Demonstrate motor and sensory deficits in the presence of nerve le- sions. Testing the Pinch Grip Procedure: The patient is asked to pick up a small object between the thumb and the index finger. Unimpaired function of the lumbricals and interossei is essential for this maneuver. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. Assessment: A sensory deficit on the radial aspect of the index finger, such as can occur in a radial nerve lesion, renders the key grip impos- sible. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. Where finger flexion is restricted, the test is repeated using an object with a larger diameter. Assessment: In the presence of injuries to the median or ulnar nerve, full finger flexion is not possible and strength is limited. Testing the Chuck Grip Procedure: The precision grip maneuver is evaluated by giving the patient a small ball and having him or her hold on to it. Assessment: This maneuver tests the strength of adduction in the thumb and finger flexion and thus allows evaluation of the median and ulnar nerves to be assessed. Testing Grip Strength Procedure: The examiner pumps a blood pressure cuff to 200 mmHg (about 26. Assessment: Patients with normal hand function should attain a value of 200 mmHg (about 26. Note that the difference in strength between men and women must be taken into account, as must that between adults and children. Radial Nerve Palsy Screening Test Screening method for the assessment of radial nerve palsy. Procedure: The patient is asked to extend his or her wrist with the elbow flexed 90°. Assessment: In radial nerve palsy affecting the wrist extensors, the patient will be unable to extend the wrist. In radial nerve palsy, the patient will be unable to abduct the thumb because of the paralysis of the abductor pollicis longus. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. Then the patient is asked to extend or abduct both the metacarpophalangeal and interphalangeal joints of the thumb. Where this nerve is damaged, thumb extension will be weakened or will not be possible as a result of paralysis of the extensor pollicis longus and brevis. In patients with degenerative joint disease or rheumatoid arthritis in the joints of the thumb, this test generally produces pain in addition to demonstrating weakness. Simple nerve palsy without degenerative changes will not produce any joint symptoms. Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved. Procedure: The patient is seated, holding the elbow slightly flexed and the forearm pronated. Assessment: Weakness or loss of supination of the forearm is a sign of supinator paralysis. This is because the biceps also participates in supination with increasing Buckup, Clinical Tests for the Musculoskeletal System © 2004 Thieme All rights reserved.
