Article Synopsis
  • The study aimed to compare energy expenditure and glycemic responses between participants with spinal cord injuries (SCI) and noninjured controls during various activities, including the use of a bionic exoskeleton.
  • It involved ten participants with chronic SCI and ten controls, measuring factors like oxygen consumption and perceived exertion during prolonged bionic ambulation.
  • Results showed that while SCI participants had lower overall exertion, the metabolic responses and energy costs were similar between groups, with bionic ambulation not significantly improving glycemic control.

The Accreditation Council for Graduate Medical Education and the American Board of Physical Medicine and Rehabilitation developed milestones for evaluation of resident physicians that include proper musculoskeletal ultrasound examination of major joints. To date, there have been no published data demonstrating acquisition and retention of these skills and correlation with the milestone evaluation. The investigators developed and implemented a curriculum in musculoskeletal ultrasound examination for Physical Medicine and Rehabilitation residents at a large academic medical center.

Quantitative ultrasound (QUS) is an inexpensive and promising tool for sensitive measurement of tendon pathology. However, few studies have reported the psychometric properties of measurements obtained using this technique for assessments of the supraspinatus tendon. The present study was undertaken to determine the variance contributed by several sources of error (participant, ultrasound operator, image analyst, analysis session) to QUS measures of the supraspinatus tendon.

Ciprofloxacin is recognized to have a deleterious relationship with tendons, particularly Achilles tendinopathy, which makes up most case reports. Tendinopathy seems to occur because of induction of collagen-degrading enzymes causing damage and ischemia of the poorly vascularized regions preventing repair. The focus on the relationship of ciprofloxacin and the Achilles tendon leaves patients on fluoroquinolones with non-Achilles tendinopathy symptoms at risk of misdiagnosis.

Upper extremity pain in persons with spinal cord injury is a common cause of morbidity. Ultrasound of nerve, muscle, and tendon has the potential to become a valuable modality in assessing this population, and has the advantage of reduced health care costs, portability, and use in populations that cannot tolerate MRI. It has the potential to detect issues before the onset of significant morbidity, and preserve patient independence.

Sarcoidosis is a multisystem granulomatous disease of unknown etiology, with prevalence ranging from 1 to 50 per 100,000. Neurologic involvement occurs in up to 5% of patients but can be the initial presentation of sarcoidosis in 50% of those affected by neurosarcoidosis. The authors report a case of mononeuritis multiplex of the ulnar and then the radial nerve that subsequently led to a diagnosis of sarcoidosis in a patient 8 mos after initial presentation.

Objective: To evaluate the correlation between age, gender, and body mass index as they relate to sacroiliac joint pathology diagnosed by dual comparative local anesthetic blocks.

Design: This was a retrospective review of patients at a university spine center from August 2001 until August 2004.

Results: One hundred fifty-eight patients underwent sacroiliac joint (SIJ) injections with average symptom duration of 34.

Recent studies have shown that not all lumbar disc herniations are symptomatic and that when followed longitudinally, these patients develop back pain independent of the previous imaging study. This is a case report of two patients with radicular symptoms and lumbar disc herniations that underwent diagnostic injections to locate their pain generator. Both patients failed to respond to transforaminal epidural steroid injections.
