Effects of fatigue and laterality on fractionated reaction time.

Surface EMG enabled fractionation of a simple hand grip total reaction time into peripheral and central processing components (motor time and premotor time respectively). Changes in reaction time components were investigated in 12 female intercollegiate swimmers (bilateral athletes) and 12 female intercollegiate tennis players (unilateral athletes) following a 48% strength decrement induced by serial maximal voluntary isometric contractions (5 sec in duration). Despite significantly greater strength in the dominant arm than in the nondominant arm, there was no difference in fatigue effects between arms. Fatigue increased the premotor component of reaction time significantly, and indirectly the total reaction time, but the motor time remained essentially constant regardless of the type of previous athletic training. This indicated that fatigue impaired central nervous system or myoneural-junction operations rather than the intramuscular ability to initiate force.

Noninvasive mapping of lower limb arterial lesions.

Thirty patients with peripheral arterial disease were evaluated using an ultrasonic duplex scanner. A total of 338 arterial segments from the level of the iliac to the popliteal artery were studied and compared with the results of arteriography read independently by two radiologists who were unaware of the results with the scanner. The results demonstrate that this method is not only suitable for clinical use but is as good as arteriography in defining both the location and extent of the arterial involvement.

Perspectives on faculty clinical practice: views of occupational therapy curriculum chairpersons and faculty members.

OBJECTIVE: This study investigated whether and how faculty clinical practice (FCP) was being implemented in occupational therapy professional education programs. METHOD: Chairpersons and faculty members from all accredited entry-level occupational therapy curricula in the United States were asked to complete questionnaires about their involvement in FCP. The chairperson questionnaire consisted of primarily closed-ended questions that addressed the organization of faculty practice within their programs, whereas the faculty questionnaire was primarily open-ended and addressed faculty members' individual involvement in FCP as well as the perceived benefits and drawbacks. Responses were analyzed for 39 program chairpersons and 136 faculty members were analyzed. RESULTS: Twenty-five chairperson respondents reported that their educational program had FCP, and 44 faculty respondents indicated involvement in FCP during the past year. FCP was more prevalent in public-funded institutions and academic health centers. Faculty members primarily engaged in FCP in order to stay current, enhance teaching, and develop networks. They reported increased credibility with students as an important benefit of clinical practice. The primary reasons faculty members did not engage in clinical practice were insufficient time and institutional policies. CONCLUSION: Although many faculty members in occupational therapy education programs value clinical practice as a part of their educator role, it is necessary to negotiate responsibilities and rewards to prevent role overload and comply with institutional policies.

Successful implementation of an automated nurse-information system. Staff development's role.

Staff development's role in the selection and implementation of a computer system based on nursing standards of practice is described. The department's instructors successfully helped staff adapt to the change and understand the integrated, automated nurse-information system. The importance of having a teaching plan to provide consistency in training sessions is discussed.
