Pain Threshold

The aim of this manuscript was to investigate the effectiveness of conservative therapy for phantom limb pain (PLP). In this systematic review, CINAHL, AMED, the Cochrane database of systematic reviews, PEDro, psychology and behavioral sciences collection, and MEDLINE were systematically searched for appropriate randomized controlled trials (RCTs). Selected papers were assessed for risk of bias, and evidence was graded using the GRADE approach. Twelve RCTs met initial inclusion/exclusion criteria, of which five were of sufficient quality for final inclusion.

AIMS: To conduct a systematic review and meta-analysis to evaluate the effectiveness of hypnosis/relaxation therapy compared to no/minimal treatment in patients with temporomandibular disorders (TMD). METHODS: Studies reviewed included randomized controlled trials (RCTs) where investigators randomized patients with TMD or an equivalent condition to an intervention arm receiving hypnosis, relaxation training, or hyporelaxation therapy, and a control group receiving no/minimal treatment.

OBJECTIVE: Acupuncture is frequently advocated as an effective treatment of dental pain. The question whether or not it is effective for this indication remains controversial. The aim of this systematic review therefore was to assess the effectiveness of acupuncture in dental pain. DATA SOURCES: Four electronic databases were searched: Medline, Embase, CISCOM, and the Cochrane Library. Only controlled trials were included in this review. DATA EXTRACTION: Information was extracted from included studies and entered on standard forms independently by both authors.

BACKGROUND: A 1977 study by Melzack et al. reported 100% anatomic and 71% clinical pain correspondences of myofascial trigger points and classical acupuncture points in the treatment of pain disorders. A reanalysis of this study's data using different acupuncture resources by Birch a quarter century later concluded that correlating trigger points to classical acupuncture points was not conceptually possible and that the only class of acupuncture points that could were the a shi points. Moreover, Birch concluded that no more than 40% of the acupuncture points examined by Melzack et al.

BACKGROUND: The effect of acupuncture on sensory perception has never been systematically reviewed; although, studies on acupuncture mechanisms are frequently based on the idea that changes in sensory thresholds reflect its effect on the nervous system. METHODS: Pubmed, EMBASE and Scopus were screened for studies investigating the effect of acupuncture on thermal or mechanical detection or pain thresholds in humans published in English or German. A meta-analysis of high quality studies was performed. RESULTS: Out of 3007 identified articles 85 were included.

Telomere length, considered a measure of biological aging, is linked to morbidity and mortality. Psychosocial factors associated with shortened telomeres are also common in chronic pain; yet, little is known about telomere length in pain populations. Leukocyte telomere length was evaluated in 66 women with fibromyalgia and 22 healthy female controls. Participants completed questionnaires and a subgroup of fibromyalgia patients underwent quantitative sensory testing (QST; n = 12) and neuroimaging (n = 12). Telomere length was measured using the quantitative polymerase chain reaction method.

Concern for the suffering of others is central to moral decision making. How humans evaluate others' suffering, relative to their own suffering, is unknown. We investigated this question by inviting subjects to trade off profits for themselves against pain experienced either by themselves or an anonymous other person. Subjects made choices between different amounts of money and different numbers of painful electric shocks. We independently varied the recipient of the shocks (self vs. other) and whether the choice involved paying to decrease pain or profiting by increasing pain.

Empathy, a basic prosocial behavior, is referred to as an ability to understand and share others' emotional state. Generally, empathy is also a social-behavioral basis of altruism. In contrast, impairment of empathy development may be associated with autism, narcissism, alexithymia, personality disorder, schizophrenia and depression. Thus, study of the brain mechanisms of empathy has great importance to not only scientific and clinical advances but also social harmony.
