Objective: To prospectively evaluate the efficacy of perimenstrual prophylaxis with eletriptan to reduce headaches in women identified with menstrual migraine (MM).

Methods: Female migraineurs self-reporting a substantial relationship between migraine and menses were evaluated with 3 consecutive months of daily headache recording diaries. A relationship between menses and migraine was evaluated using International Classification of Headache Disorders (ICHD-II) criteria and a probability model called Probability MM.

Efficacy of percutaneous electrical nerve stimulation and therapeutic exercise for older adults with chronic low back pain: a randomized controlled trial.

Chronic low back pain (CLBP) in older adults may be disabling and therapeutically challenging, largely because of the inefficacy and/or morbidity associated with traditional pain treatment. We conducted a randomized controlled trial in 200 men and women > or = age 65 with CLBP to evaluate the efficacy of percutaneous electrical nerve stimulation (PENS) with and without general conditioning and aerobic exercise (GCAE), for reducing pain and improving physical function. Participants were randomized to receive (1) PENS, (2) control-PENS (brief electrical stimulation to control for treatment expectancy), (3) PENS+GCAE, or (4) control-PENS+GCAE, twice a week for 6 weeks.

Classifying subgroups of chronic low back pain patients based on lifting patterns.

Objective: To compare self-reported measures of chronic lower back pain (CLBP) patients who were assigned to 2 subgroups based on their lifting patterns performed during a repetitive lifting task.

Design: Cross-sectional study.

Setting: Research laboratory

Participants: CLBP subjects (n=81) and pain-free controls (n=53).

Couple-Oriented Education and Support Intervention for Osteoarthritis: Effects on Spouses' Support and Responses to Patient Pain.

The purpose of this study was to determine whether a couple-oriented education and support intervention for osteoarthritis was more efficacious than a similar patient-oriented intervention in terms of enhancing spouses' support of patients and their positive and negative responses to patient pain. Repeated-measures analyses of covariance with the completers sample (N = 103 dyads) showed that at the postintervention assessment, patients in the couple-oriented intervention reported a greater decrease in their spouses' punishing responses (e.g.

Evaluating reliability of hidden Markov models that describe the lifting patterns of chronic lower back pain patients and controls.

Two hidden Markov models (HMMs) were designed to identify sub-groups of chronic lower back pain (CLBP) subjects based on time series of lifting parameters obtained during a repetitive lifting task. Two simulation studies were conducted to determine the reliability of this approach, using data from the repetitive lifting study. The first simulation verifies that control and CLBP HMMs based on these data can reliably identify sequences that were generated from that model.

Efficacy of periosteal stimulation therapy for the treatment of osteoarthritis-associated chronic knee pain: an initial controlled clinical trial.

Objectives: To examine the efficacy of periosteal stimulation therapy (PST, osteopuncture) for the treatment of chronic pain associated with advanced knee osteoarthritis.

Design: Randomized, controlled clinical trial.

Setting: Outpatient pain clinic.

The impact of chronic low back pain on older adults: a comparative study of patients and controls.

Chronic low back pain (CLBP) is one of the most common, poorly understood, and potentially disabling chronic pain conditions from which older adults suffer. Many older adults remain quite functional despite CLBP, and because age-related comorbidities often exist independently of pain (e.g.

An interdisciplinary expert consensus statement on assessment of pain in older persons.

This paper represents an expert-based consensus statement on pain assessment among older adults. It is intended to provide recommendations that will be useful for both researchers and clinicians. Contributors were identified based on literature prominence and with the aim of achieving a broad representation of disciplines.

Older spouses' perceptions of partners' chronic arthritis pain: implications for spousal responses, support provision, and caregiving experiences.

This study of older patients with osteoarthritis and their spouses examined concordance between patients' and spouses' reports of patients' pain severity and the association of concordance with support and caregiving outcomes. Patients and spouses independently viewed videotapes of the patient performing simulated household tasks and provided ratings of patients' pain. Spousal overestimation of patients' pain was the most common type of nonconcordance.

The relationship between pain, neuropsychological performance, and physical function in community-dwelling older adults with chronic low back pain.

Objective: Chronic pain and cognitive impairment are prevalent and disabling in older adults (OA), but their interrelationship has not been rigorously tested. We did so in OA with chronic low back pain (CLBP).

Design: A total of 323 OA (160 pain-free, 163 CLBP; mean age 73.

The use of splines to calculate jerk for a lifting task involving chronic lower back pain patients.

Motion differences in a repetitive lifting task have been described previously using differences in the timing of body angle changes during the lift. These timing changes relied on small differences of motion and are difficult to measure. The purpose of this study was to evaluate shoulder jerk (rate of change of acceleration) in a repetitive lifting task as an alternative parameter to detect differences of motion between controls and chronic lower back pain (CLBP) patients and to measure the impact of a rehabilitation program on jerk.

Fibromyalgia and headache: an epidemiological study supporting migraine as part of the fibromyalgia syndrome.

Fibromyalgia is defined by widespread body pain, tenderness to palpation of tender point areas, and constitutional symptoms. The literature reports headache in about half of fibromyalgia patients. The current epidemiological study was designed to determine the prevalence and characteristics of headache in fibromyalgia patients.

Do medical factors predict disability in older adults with persistent low back pain?

Persistent low back pain (LBP) is one of the most common and challenging persistent pain conditions in older adults. Medical comorbidity also is common in these individuals, but its impact on disability has not been examined. The purpose of this study was, using a cross-sectional design, to examine the functional impact of pain-related and general medical comorbidity on 100 community dwelling older adults (mean age 74.

Effects of a stress-reduction program on psychological function, pain, and physical function of systemic lupus erythematosus patients: a randomized controlled trial.

Objective: To assess the effects of a stress-reduction program on pain, psychological function, and physical function in persons with systemic lupus erythematosus (SLE) who experience pain.

Methods: Ninety-two SLE patients were assigned randomly to receive either biofeedback-assisted cognitive-behavioral treatment (BF/CBT), a symptom-monitoring support (SMS) intervention, or usual medical care (UC) alone.

Results: BF/CBT participants had significantly greater reductions in pain and psychological dysfunction compared with the SMS group (pain, P = 0.

Diagnosis of migrainous vertigo: validity of a structured interview.

Background: Migraine and vestibular symptoms are co-morbid. Migraine is increasingly recognized as a cause of benign, recurrent vertigo. Although the International Headache Society does not currently include the diagnosis of migrainous vertigo, specific criteria have been proposed and utilized in clinical trials.

Validation of a brief nurse-administered migraine assessment tool.

Objective: To validate a brief tool for screening migraine.

Background: Migraine is a common, but underdiagnosed condition. Effective utilization of nonphysician personnel to reliably screen patients for migraine may improve identification of migraineurs for clinical treatment and research.

Effects of disease activity, pain, and distress on activity limitations in patients with systemic lupus erythematosus.

Objective: To evaluate the extent to which disease activity, pain, and psychological distress predict activity limitations in persons with systemic lupus erythematosus (SLE).

Methods: A sample of 93 persons with SLE completed medical and psychosocial evaluations at one study visit. Sets of measures were chosen to represent constructs of Disease Activity, Pain, Distress, and Activity Limitations.

LBP patients were recruited and tested at an outpatient ambulatory chronic pain rehabilitation program before treatment was begun.

The association between wear facets, bruxism, and severity of facial pain in patients with temporomandibular disorders.

Statement Of Problem: It is unclear whether patients with temporomandibular disorders (TMD) who report high levels of bruxism have more severe signs and symptoms of TMD and more advanced tooth wear than patients with TMD who report lower levels of bruxism.

Purpose: The purpose of this study was to determine whether there was a significant association between tooth wear, the parafunctional oral habit of bruxism, temporomandibular joint (TMJ) pain, and muscle pain severity in a TMD population.

Material And Methods: A total of 84 subjects previously diagnosed with TMD, according to the Research Diagnostic Criteria for TMD (RDC/TMD) and who met 10 specific inclusion/exclusion criteria underwent a thorough multiaxial examination and classification recommended by the National Institute of Dental and Craniofacial Research (NIDCR).

Adaptation to chronic pain in systemic lupus erythematosus: applicability of the multidimensional pain inventory.

Objectives: 1) Investigate psychosocial adaptation to chronic pain in patients with systemic lupus erythematosus; 2) Compare pain adaptation of lupus, chronic low back pain, and temporomandibular disorders patients; and 3) Evaluate the validity of Multidimensional Pain Inventory-based profiles of lupus patients.

Methods: Two hundred forty females with pain related to systemic lupus erythematosus (N =80), chronic low back pain (N=80), or pain related to temporomandibular disorders (N=80) completed the Multidimensional Pain Inventory, a 60-item psychosocial assessment instrument. All patients were classified into empirically derived profiles based on Multidimensional Pain Inventory responses.

Relation of jaw sounds and kinematics visualized and quantified using 3-D computer animation.

The management of jaw pain or temporomandibular disorders (TMD) has been controversial regarding temporomandibular joint (TMJ) sounds and their implication regarding TMD prognosis. 3-D computer animation was used to visualize and quantify the internal mechanics of natural mandibular motion synchronized with TMJ sounds. Mandibular movements of four TMD patients and two healthy subjects were recorded using CCD cameras and reflective markers.

Mandibular kinematics represented by a non-orthogonal floating axis joint coordinate system.

There are many methods used to represent joint kinematics (e.g., roll, pitch, and yaw angles; instantaneous center of rotation; kinematic center; helical axis).
