How physician assistants use and perceive complementary and alternative medicine.

The use of complementary and alternative medicine (CAM) is growing in the United States. Patients and their health care providers are increasingly accepting of complementary and alternative therapies. The purpose of this study was to identify physician assistants' (PAs') attitudes, beliefs, knowledge, training, recommendations for, and personal use of CAM. A random sample of 500 practicing PAs was sent a four-page, 78-item survey investigating their personal use of, recommendations for, and perceptions of the efficacy and safety of complementary and alternative therapies. Of PAs eligible to complete the survey, 50% responded. Chi-square analyses found a significant relationship between knowledge level and recommendation for CAM; status of use and belief that CAM exerts a placebo effect; status of use and recommendation for CAM; and source of information on CAM and recommendation for CAM. With the increasing prevalence of use of CAM, PAs need to be informed regarding CAM therapies.

Static stabilometry, transcranial Doppler, and single photon emission computed tomography in patients with central dizziness.

Previous studies have found that transcranial doppler (TCD) and single photon emission computed tomography (SPECT) are effective means of diagnosing cerebral blood flow disorders in patients with central dizziness whose etiology was unknown by standard audiologic and/or vestibular assessment techniques. Also, static stabilometry, which measures a person's standing center of pressure (COP) movements, has been used to distinguish between patients with central neurologic and peripheral vestibular disorders. The purpose of this retrospective study was to examine the relation between TCD, SPECT, and stabilometry in patients with central dizziness attributable to cerebral blood flow disorders. Stabilometry testing was conducted on 50 normal subjects and 31 subjects with dizziness, the latter group consisting of persons with cerebral dysautoregulation, migraines, and unknown etiology with negative or positive SPECT results. The results indicated that patients with cerebral dysautoregulation were not significantly different from normal subjects or the other three groups in their COP movements. The other three groups exhibited significantly higher COP movements than the normal subjects, particularly when visual inputs were compromised. Patients with negative SPECT results were significantly different in their COP movements from the other three groups of subjects with dizziness. These results suggest that the pattern of COP movements may be useful in identifying patients with postural dysfunctions whose etiology may then be detected by TCD and SPECT.

Effect of helium-neon laser irradiation on peripheral sensory nerve latency.

The purpose of this randomized, double-blind study was to determine the effect of a helium-neon (He-Ne) laser on latency of peripheral sensory nerve. Forty healthy subjects with no history of right upper extremity pathological conditions were assigned to either a Laser or a Placebo Group. Six 1-cm2 blocks along a 12-cm segment of the subjects' right superficial radial nerve received 20-second applications of either the He-Ne laser or a placebo. We assessed differences between pretest and posttest latencies with t tests for correlated and independent samples. The Laser Group showed a statistically significant increase in latency that corresponded to a decrease in sensory nerve conduction velocity. Short-duration He-Ne laser application significantly increased the distal latency of the superficial radial nerve. This finding provides information about the mechanism of the reported pain-relieving effect of the He-Ne laser.

Developing effective questionnaires.

Many research questions are effectively answered by collecting data about the opinions, beliefs, and perceptions of large numbers of persons in widely dispersed areas. The questionnaire is an economical means of gathering such information. Properly designed questionnaires can collect valid and reliable data for analyzing a research problem. This article reviews fundamental principles of questionnaire design and presents a matrix to guide the construction of a questionnaire. Methods to avoid common problems and pitfalls in developing a questionnaire are also presented. Field testing is recommended to ensure validity and reliability.

Tenure and the allied health professions: issues and alternatives.

This article traces the development of tenure from its origins to modern times. External and internal pressures and constraints which have led to a debate on the nature and need for the existence of tenure are described. The traditional and alternative tenure models are set forth. The impact of the tenure process upon the allied health professions is discussed, and the authors recommend that the allied health professions should strive for professional parity by adopting the traditional criteria for tenure.
