Barbara A. Rakel

ABSTRACT: BACKGROUND: Osteoarthritis of the knee is a major clinical problem affecting a greater proportion of women than men. Women generally report higher pain intensity at rest and greater perceived functional deficits than men. Women also perform worse than men on function measures such as the 6-minute walk and timed up and go tests. Differences in pain sensitivity, pain during function, psychosocial variables, and physical activity levels are unclear. Further the ability of various biopsychosocial variables to explain physical activity, function and pain is unknown. METHODS: This study examined differences in pain, pain sensitivity, function, psychosocial variables, and physical activity …

Effectiveness Of Transcutaneous Electrical Nerve Stimulation On Postoperative Pain With Movement, Barbara Rakel, Rita Frantz

Barbara A. Rakel

This study tested the effectiveness of episodic transcutaneous electrical nerve stimulation (TENS) as a supplement to pharmacologic analgesia on pain with movement and at rest after abdominal surgery and evaluated whether its use during walking and vital capacity maneuvers enhances performance of these activities. TENS, with a modulated frequency, intensity as high as the subject could tolerate, and electrodes placed on either side and parallel to the incision, was compared to placebo TENS and pharmacologic analgesia alone (control) by using a crossover design. Self-report of pain intensity, walking function, and vital capacity were assessed on 33 subjects. TENS resulted in …

An Investigation Of The Development Of Analgesic Tolerance To Tens In Humans, R. Liebano, B. Rakel, C. Vance, D. Walsh, K. Sluka

Barbara A. Rakel

Transcutaneous electrical nerve stimulation (TENS) is a noninvasive modality used to control pain. Animal models show that repeated TENS application produces analgesic tolerance and cross-tolerance at spinal opioid receptors. The aim of the present investigation was to examine whether repeated application of TENS produces analgesic tolerance in humans. One hundred healthy subjects were randomly assigned to 1 of 4 groups: control, placebo, low-frequency (4Hz) or high-frequency (100Hz) TENS. TENS was applied daily for 5days to the nondominant upper limb; pressure-pain threshold (PPT) measurements were recorded before and after TENS. Temporal summation to mechanical stimulation was recorded on days 1 and …


Nonpharmacologic Treatment Of Pain, M. Titler, B. Rakel May 2012

Nonpharmacologic Treatment Of Pain, M. Titler, B. Rakel

Barbara A. Rakel

Nonpharmacologic interventions for pain treatment are important complementary therapies but are not substitutes for pharmacologic management of pain. Use of nonpharmacologic pain treatments in critical care settings is helpful to decrease pain, but the challenge remains for nurses to have the knowledge, time, and skill to use these interventions in a busy daily practice with severely ill patients. Although numerous studies testing the effectiveness of nonpharmacologic interventions for pain management are available, the varying methods and interventions used in these studies make it difficult to draw conclusions. Further research on the use of these interventions for pain reduction is necessary …

Clinical Outcome Of Emergency Repeat Coronary Artery Bypass Surgery, J. Lemmer, D. Ferguson, Barbara Rakel, N. Rossi

Barbara A. Rakel

To determine the clinical outcome of patients requiring emergency repeat coronary artery bypass graft (CABG) procedures, we reviewed 23 such procedures performed for ongoing myocardial ischemia refractory to medical management. The operative mortality was 17%. On follow-up, an average of 24.9 months after emergency reoperation, 14 of the 19 survivors (74%) had recurrent angina. As compared to a randomly selected group of 25 patients who underwent elective repeat CABG procedures during the same time period, the incidence of late cardiac events was significantly higher (79% in the emergency group, 30% in the elective surgery group) and fewer patients had received …


Physical Modalities In Chronic Pain Management, Barbara Rakel, J. Barr May 2012

Physical Modalities In Chronic Pain Management, Barbara Rakel, J. Barr

Barbara A. Rakel

The following conclusions can be made based on review of the evidence: There is limited but positive evidence that select physical modalities are effective in managing chronic pain associated with specific conditions experienced by adults and older individuals. Overall, studies have provided the most support for the modality of therapeutic exercise. Different physical modalities have similar magnitudes of effects on chronic pain. Therefore, selection of the most appropriate physical modality may depend on the desired functional outcome for the patient, the underlying impairment, and the patient's preference or prior experience with the modality. Certain patient characteristics may decrease the effectiveness …

Adjusting Pulse Amplitude During Transcutaneous Electrical Nerve Stimulation (Tens) Application Produces Greater Hypoalgesia, M. Pantaleao, M. Laurino, N. Gallego, C. Cabral, Barbara Rakel, C. Vance, K. Sluka, D. Walsh, R. Liebano

Barbara A. Rakel

Transcutaneous electrical nerve stimulation (TENS) is a noninvasive technique used for pain modulation. During application of TENS there is a fading of current sensation. Textbooks of electrophysical agents recommend that pulse amplitude should be constantly adjusted. This seems to be accepted clinically despite the fact that there is no direct experimental evidence. The aim of the current study was to investigate the hypoalgesic effect of adjusting TENS pulse amplitude on pressure pain thresholds (PPTs) in healthy humans. Fifty-six healthy TENS naive participants were recruited and randomly assigned to 1 of 4 groups (n = 14 per group): control, placebo TENS, …

Effectiveness Of Transcutaneous Electrical Nerve Stimulation For Treatment Of Hyperalgesia And Pain, J. Desantana, D. Walsh, C. Vance, Barbara Rakel, K. Sluka

Barbara A. Rakel

Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacologic treatment for pain relief. TENS has been used to treat a variety of painful conditions. This review updates the basic and clinical science regarding the use of TENS that has been published in the past 3 years (ie, 2005-2008). Basic science studies using animal models of inflammation show changes in the peripheral nervous system, as well as in the spinal cord and descending inhibitory pathways, in response to TENS. Translational studies show mechanisms to prevent analgesic tolerance to repeated application of TENS. This review also highlights data from recent randomized, placebo-controlled trials …

Creating more sophisticated models that describe and value nursing care will enable more sophisticated management of nursing resources. The authors used the Nursing Interventions Classification (NIC) as the basis for describing actions performed by nurses. Nursing experts evaluated each intervention in order to assign the time required for each task and the minimum level of education required to perform each task. Fifty-four percent of the interventions were determined to require fewer than 30 minutes. Over 70% of the interventions in the NIC were deemed to require basic RN education to per-form them safely and appropriately. With the time and skill …

Improving Practice Through Research: The Case Of Heparin Vs. Saline For Peripheral Intermittent Infusion Devices, C. Goode, Charmaine Kleiber, M. Titler, S. Small, Barbara Rakel, Victoria Steelman, J. Walker, Kathleen Buckwalter Nov 2011

Improving Practice Through Research: The Case Of Heparin Vs. Saline For Peripheral Intermittent Infusion Devices, C. Goode, Charmaine Kleiber, M. Titler, S. Small, Barbara Rakel, Victoria Steelman, J. Walker, Kathleen Buckwalter

Barbara A. Rakel

Peripheral intermittent infusion devices are commonly used to administer periodic doses of medications to adults and children. Research findings provide a strong base for changing practice to using saline instead of heparin to flush these devices in children over 28 days old and in adults. This research-based change in practice will enhance the quality of care that patients receive and decrease the costs of their care.
