Controlled randomized trials have demonstrated the efficacy, safety, effectiveness, and cost-effectiveness of neuroreflexotherapy (NRT) for the management of non-specific back pain. In this audit study, we describe the implementation of NRT into the routine practice of primary care within the Spanish public health service of the Balearic Islands and the results obtained after one year (2004). A referral protocol was made available to all general practitioners (GPs) who could refer eligible patients to specialized units in performing NRT interventions. ⋯ Adverse effects related to the procedure were only a skin reaction in 3.3% of patients. We conclude that it is feasible to implement NRT in the public health service complying with methods and application conditions used in previous randomized controlled trials (RCTs). In such conditions, implementation of this technology obtained positive audit results at one year.

Comparative Study
Chronic pain and the emotional brain: specific brain activity associated with spontaneous fluctuations of intensity of chronic back pain.
Living with unrelenting pain (chronic pain) is maladaptive and is thought to be associated with physiological and psychological modifications, yet there is a lack of knowledge regarding brain elements involved in such conditions. Here, we identify brain regions involved in spontaneous pain of chronic back pain (CBP) in two separate groups of patients (n = 13 and n = 11), and contrast brain activity between spontaneous pain and thermal pain (CBP and healthy subjects, n = 11 each). Continuous ratings of fluctuations of spontaneous pain during functional magnetic resonance imaging were separated into two components: high sustained pain and increasing pain. ⋯ In contrast, the increasing phase of CBP transiently activated brain regions commonly observed for acute pain, best exemplified by the insula, which tightly reflected duration of CBP. When spontaneous pain of CBP was contrasted to thermal stimulation, we observe a double-dissociation between mPFC and insula with the former correlating only to intensity of spontaneous pain and the latter correlating only to pain intensity for thermal stimulation. These findings suggest that subjective spontaneous pain of CBP involves specific spatiotemporal neuronal mechanisms, distinct from those observed for acute experimental pain, implicating a salient role for emotional brain concerning the self.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of a single botulinum type A toxin complex treatment (Dysport) for the relief of upper back myofascial pain syndrome: results from a randomized double-blind placebo-controlled multicentre study.
Botulinum type A toxin (BoNT-A) has antinociceptive and muscle-relaxant properties and may help relieve the symptoms of myofascial pain syndrome. In this study we evaluated the efficacy and tolerability of BoNT-A (Dysport) in patients with myofascial pain syndrome of the upper back. We conducted a prospective, randomized, double-blind, placebo-controlled, 12-week, multicentre study. ⋯ Treatment was well tolerated, with most side effects resolving within 8 weeks. In conclusion, in patients with upper back myofascial pain syndrome, injections of 400 Ipsen units of Dysport at 10 individualised trigger points significantly improved pain levels 4-6 weeks after treatment. Injections were well tolerated.

Interdisciplinary rehabilitation in fibromyalgia and chronic back pain: a prospective outcome study.
This study aimed to examine short-term and mid-term course of health, biopsychosocial functional ability, and coping performance of patients with fibromyalgia (FM) or chronic back pain (BP) after participation in a standardized 4-week inpatient, interdisciplinary pain rehabilitation program. In a prospective cohort study, assessments were made by using a set of standardized, well-tested self-rating instruments and other parameters before and after the intervention up to the 6-month follow-up with standardized effect sizes (ES) and comparison to population norms. The effects of improvements in health and coping domains on pain reduction were examined by linear regression modeling. The health of the 65 FM and the 60 BP patients at baseline was far worse than expected from the norms. Improvements included ES up to 1.09 for pain, physical role performance, and mental/affective health dimensions and 0.50 in coping at discharge from the clinic. At the 6-month follow-up, all effects were consistently lower but still up to ES = 0.75. Improvements of FM and BP were equal at discharge but slightly better for the FM's mood scales at the 6-month follow-up. Physical and social function, mood, and coping were significantly associated with pain reduction. ⋯ Inpatient, structured interdisciplinary rehabilitation covering elements of cognitive and operant behavioral therapy, graded activity exercise, and adapted drug therapy revealed moderate to large short-term and mid-term improvements in physical and mental health and in the major coping dimensions as captured by comprehensive and specific assessment.

Review and analysis of data from two U.S. national surveys in 2002. ⋯ About one fourth of U.S. adults report low back pain in the past 3 months; the proportion of physician visits attributed to back pain has changed little in the past decade.
