Optimal methods for shoulder tendon palpation: a cadaver study.

BACKGROUND AND PURPOSE: Physical therapists often must either palpate tendons of the shoulder or, as part of treatment, apply forces to those tendons. Many methods have been suggested for minimizing the amount of soft tissue that overlies these tendons, but no data have been presented to justify the use of any approach. The purpose of this study was to evaluate methods described in the literature by use of cadaver models. SUBJECTS: Twenty-four shoulders from 12 cadavers of individuals aged 55 to 92 years were dissected. METHODS: Shoulders were placed in the positions described in the literature, and the positions in which the tendons were maximally exposed (ie, had the least overlying tissue) were noted. RESULTS: Positions were found in which tendons were maximally exposed. CONCLUSION AND DISCUSSION. Positions described in the literature for optimizing the exposure of shoulder tendons are not always optimal, and palpation and treatment may be improved by using positions determined by research such as those suggested in this report.

Teaching human anatomy in physical therapy education in the United States: a survey.

BACKGROUND AND PURPOSE: The purpose of this study was to determine how human anatomy was being taught in physical therapy programs in the United States. SUBJECTS: Faculty in 103 physical therapy programs participated in the study. METHODS: A six-page questionnaire, which was mailed to 145 physical therapy programs, contained five sections: demographics, human gross anatomy--present and future, administration/cost, human anatomy textbooks, and human gross anatomy content areas. RESULTS: Anatomy was a laboratory-intensive course, with dissection being the primary laboratory teaching method. Use of prosected specimens, various audiovisuals, and computer-assisted instruction was also documented. Half of those teaching anatomy had a degree in physical therapy, and 65.6% of these educators were doctorally prepared. When comparing anatomy courses taught by physical therapy faculty and non-physical therapy faculty, differences existed between the two groups with respect to course content and clinical applicability. The most significant difference in content area emphasis was noted in the thoracic area. CONCLUSION AND DISCUSSION: Differences noted in course-content emphasis demonstrate the necessity for physical therapy faculty to communicate with non-physical therapy faculty teaching human anatomy about course content. Although the survey results have indicated that numerous texts are in use, the value placed on clinical applicability remains a significant consideration.

Peripheral nerve axonal dwindling with concomitant myelin sheath hypertrophy in experimentally induced diabetes.

Axons of the peripheral nervous system (PNS) are reduced in caliber in response to the experimental diabetic state. The cause of this reduced axonal size is disputed. Various theories include (a) axonal dwindling, (b) inhibition of growth, and (c) shrinkage due to serum hyperosmolarity. This study was designed to directly address these conflicting theories and to provide additional information on the character of the peripheral neuropathy resulting from an experimentally induced diabetic state. Four weeks, 6 and 12 months after establishing a streptozotocin-induced diabetic condition in rats, a morphometric evaluation of randomly selected cross sections of myelinated nerve fibers in the common peroneal nerve was performed on diabetic and age and weight-matched control animals. A reduction in the cross-sectional area of axons with a concomitant increase in the width of myelin sheaths was detected following 6 months of exposure to the diabetic state. Axons in rats diabetic for 12 months showed smaller cross-sectional areas than those seen in rats diabetic for only 6 months; hence, a dwindling in axonal caliber had occurred during this period. These findings indicate the presence of an axonopathy, associated with a myelin sheath alteration in the common peroneal nerve of the chronically diabetic rat.

Peripheral neuropathy following prolonged exposure to streptozotocin-induced diabetes in rats: a teased nerve fiber study.

An experimental diabetic state was induced in rats by means of an injection of streptozotocin. A histological and histometric evaluation of randomly teased nerve fibers was applied to the common peroneal nerves of both diabetic and age- and weight-matched control rats. A long-term (6-12 months) exposure to the diabetic state was required for the demonstration of the following morphological changes: (1) splitting and notching of myelin sheaths, (2) decrease in the ratio of internodal length/internodal diameter, (3) widening of nodal gaps. This study showed that neurons of smaller caliber are preferentially affected after a prolonged period of the diabetic condition. Neurons of this size are representative of sensory and autonomic components, suggesting that the changes present in this model parallel the derangements of these constituents reported in the human diabetic with adult onset disease.
