Background: The McGill Pain Questionnaire (MPQ) pain quality descriptors have been analyzed to characterize the sensory, affective, and evaluative domains of pain, but have not been differentiated by pain location., Aim: To examine MPQ pain quality descriptors by pain location in outpatients with lung or prostate cancer., Design: Cross sectional., Settings: Eleven oncology clinics or patients' homes., Subjects: 264 adult outpatients (80% male; mean age 62.2 ± 10.0 years, 85% White)., Methods: Subjects completed a 100 mm visual analogue scale of pain intensity and MPQ clinic or home visit, marking sites where they had pain on a body outline and circling from 78 verbal descriptors those that described their pain. A researcher noted next to the descriptor spontaneous comments about sites feeling like a selected word and queried the subjects about any other words to obtain the site(s)., Results: Pain quality descriptors were assigned to all 7 pain locations marked by ≥ 20% of 198 lung or 66 prostate cancer patients. Four pain locations were marked with pain quality descriptors significanlty (p < .05) more frequently for lung cancer (53% chest-aching, burning; 58% back-aching, stabbing; 48% head-aching, sharp; and 19% arms-aching, stabbing) than for prostate cancer, which had significantly more frequent pain locations in the abdomen (64%-aching, burning) and lower back/buttocks (55%-aching, burning)., Conclusions: This type of pain characterization is innovative and has the potential to help implement targeted treatments for patients with cancer and other chronic pain conditions., (Copyright © 2019 American Society for Pain Management Nursing.

Objectives: This study investigated the effect of acupuncture needles developed for double-blind (practitioner-patient blinding) trials employing a tapping-in method that is commonly used to penetrate the skin in Japanese-style acupuncture. DESIGN, SUBJECTS, AND INTERVENTIONS: An acupuncturist applied a penetrating, a skin-touch placebo, and a no-touch control needle designed to blind both practitioners and patients in the forearm in 80 healthy subjects (patients) by tapping-in method., Setting: The setting was a practice room of the Japan School of Acupuncture, Moxibustion and Physiotherapy, Tokyo, Japan., Outcome Measures: The outcome measures were the acupuncturist's and subjects' guesses at the type of needles and confidence of their guesses on a 100-mm visual analogue scale (VAS). The subjects were asked about pain with needle application., Results: The number of correct/incorrect guesses (the latter including unidentified) of the acupuncturist were 73/167 with a confidence of 55.2 ± 16.9 (mean ± standard deviation) on the VAS. The subjects identified 148 needles correctly and 92 needles incorrectly, the mean confidence being 71.0 ± 28.4. There were a few penetrating and skin-touch placebo needles that the subjects guessed as "no-touch." Whereas few of the 80 no-touch control needles were guessed as "penetrating," 16% of them were guessed as "skin-touch" and 11% were reported as "unidentifiable" by the subjects. Forty percent (40%) of the penetrating needles and 50% of the skin-touch placebo needles did not elicit skin penetration pain., Conclusions: The effect of practitioner blinding employing the needles for double blinding with the tapping-in method was satisfactory. It was difficult to blind the subjects when no-touch control needles together with penetrating and skin-touch placebo needles were used.

Background and Objectives: No studies have reported corrugator muscle activity associated with pain in people with pain. This study aimed to develop an objective pain assessment method using corrugator muscle activity with pressure pain stimulation to the skeletal muscle. Methods: Participants were 20 adults (a mean ± SD age of 22.0 ± 3.1 years) with chronic neck/shoulder pain. Surface electromyography (sEMG) of corrugator muscle activity at rest (baseline) and without and with pressure pain stimulation applied to the most painful tender point in the shoulder was recorded. Participants evaluated the intensity of the neck/shoulder pain and the sensory and affective components of pain with pressure stimulation using a visual analogue scale (VAS). The percentages of integrated sEMG (% corrugator activity) without and with pressure pain stimulation to the baseline integrated sEMG were compared, and the relationships between the % corrugator activity and the sensory and affective components of pain VAS scores were evaluated. Results: Without pressure stimulation, an increase in corrugator muscle activity due to chronic neck/shoulder pain was not observed. The % corrugator activity with pressure pain stimulation was significantly higher than that without stimulation (p < 0.01). A significant positive correlation between corrugator muscle activity and the affective components of pain VAS scores with pressure stimulation was found (ρ = 0.465, p = 0.039) and a tendency of positive correlation was found for the sensory component of pain VAS scores (ρ = 0.423, p = 0.063). Conclusions: The increase in corrugator muscle activity with pressure pain stimulation to the tender point in adults with chronic neck/shoulder pain was observed, although increased corrugator muscle activity resulting from the chronic neck/shoulder pain was not. These findings suggest that corrugator muscle activity with pressure pain stimulation can be a useful objective indication for tender point sensitivity assessment in the skeletal muscle with pain.

Purpose: Describe perceptions of patients with rheumatoid arthritis (RA) regarding disease-related pain, tendency to tell others about their pain, and treatments used since diagnosis. Design: Cross sectional, exploratory. Method: A total of 63 participants responded to telephone interview about their treatments and tendency to tell others about their RA pain. They also responded to McGill Pain Questionnaire and Health Assessment Questionnaire (HAQ) items. Participants marked pain location on mailed body outlines. Findings: RA diagnosis occurred an average of 11 years prior. Mean HAQ Standard Disability Index score was 1.26. Previous week symptoms were joint pain (97%), joint swelling (83%), decreased movement/function (83%), fatigue (70%), muscle weakness (65%). Mean morning stiffness duration was 120 ± 137 minutes. Mean pain intensity was 1.15 ± 0.6 at its least and 3.8 ± 1.1 at its worst. 65% were not satisfied with pain levels. 57% stated a tendency not to tell others about their pain; 43% tended to tell. 78% used medications and alternative therapies, none solely used alternative therapies, and 22% only used medications. Conclusions: RA patients reported high rates of alternative therapy use. Dissatisfaction with pain levels indicates need for improved pain management. Not talking about pain lends insights into the importance of teaching patients to communicate their pain to others. [ABSTRACT FROM AUTHOR]

Acupuncture and acupressure, 2 modalities of Traditional Chinese Medicine, are based on reducing pain and symptoms of disease through balancing yin and yang. Acupuncture and acupressure have been used in China for reduction of labor pain, labor augmentation, and other intrapartum indications for more than 2 millennia. This article presents a review of the current literature that has addressed the effects of acupuncture and acupressure on intrapartum events. Studies of acupuncture have demonstrated that acupuncture may reduce labor pain, the use of pharmacologic agents, the use of forceps and vacuum-assisted births, and the length of labor. Studies that examined the effect of acupuncture on labor that is induced or augmented for premature rupture of membranes have found that acupuncture may increase the degree of cervical ripening but does not reduce the amount of oxytocin or epidural analgesia administration, nor does it shorten length of induced labor. Acupressure may reduce labor pain and labor duration, but acupressure has not been found to increase cervical ripening or induce labor. There are insufficient studies about acupuncture and acupressure and their effects on labor at this time, and there is need for further research. Areas of uncertainty include efficacy, optimal point selection, best techniques, and length of time for point stimulation. [ABSTRACT FROM AUTHOR]
