ABSTRACT
Multimodal therapies comprising spa applications are widely used as non-pharmaceutical treatment options for musculoskeletal diseases. The purpose of this randomized, controlled, open pilot study was to elucidate the involvement of the endocannabinoid system in a multimodal therapy approach. Twenty-five elderly patients with knee osteoarthritis (OA) received a 2-week spa therapy with or without combination of low-dose radon therapy in the Bad Gastein radon gallery. A 10-point numerical rating scale (pain in motion and at rest), WOMAC questionnaire, and the EuroQol-5D (EQ-5D) questionnaire were recorded at baseline, and during treatment period at weeks one and two, and at 3-month and 6-month follow-ups. Plasma levels of the endocannabinoid anandamide (AEA) were determined at baseline and at 2 weeks, and serum levels of several cartilage metabolism markers at all five time-points. A significant and sustained reduction of self-reported knee pain was observed in the study population, but no further significant effect of the additional radon therapy up and above base therapy. This pain reduction was accompanied by a significant reduction of AEA plasma levels during treatment in both groups. No significant differences were seen in serum marker concentrations between the groups treated with or without radon, but a small reduction of serum cartilage degradation markers was observed during treatment in both groups. This is the first study investigating AEA levels in the context of a non-pharmacological OA treatment. Since the endocannabinoid system represents a potential target for the development of new therapeutics, further studies will have to elucidate its involvement in OA pain.

The SARS-CoV2 has infected millions of humans worldwide in the past few months and hundreds of thousands have died as a result of an infection. The end of the pandemic is not in sight and many people are anxious of becoming infected in different settings. The Gastein Healing Gallery (GHG) is a unique outpatient facility combining heat, high humidity and mild radon radiation. Every year approximately 12,000 patients with inflammatory rheumatic, degenerative diseases and chronic pain are treated. We have therefore reviewed and analyzed the literature with respect to a possible increased risk of infection for patients during treatment in the GHG. On the one hand the climatic and physical conditions in the GHG can be viewed as hostile to viruses and on the other hand the mild radon hyperthermia and the geographic location of the GHG lead to positive effects on the patient's health via complex physiological processes. We therefore consider the likelihood of infection with viruses in the GHG in no way increased, in contrast, it is probably considerably lower compared to other settings.
ABSTRACT
BACKGROUND: The regular update of the guidelines on fibromyalgia syndrome, AWMF number 145/004, was scheduled for April 2017. METHODS: The guidelines were developed by 13 scientific societies and 2 patient self-help organizations coordinated by the German Pain Society. Working groups (n =8) with a total of 42 members were formed balanced with respect to gender, medical expertise, position in the medical or scientific hierarchy and potential conflicts of interest. A systematic search of the literature for systematic reviews of randomized, controlled studies on psychological and psychotherapeutic procedures from December 2010 to May 2016 was performed in the Cochrane library, MEDLINE, PsycINFO and Scopus databases. Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine version 2009. The strength of recommendations was achieved by multiple step formalized procedures to reach a consensus. Efficacy, risks, patient preferences and applicability of available therapies were weighed up against each other. The guidelines were reviewed and approved by the board of directors of the societies engaged in the development of the guidelines. RESULTS AND CONCLUSION: Cognitive behavioral therapies received a strong recommendation but biofeedback, guided imagery and hypnosis received a weak recommendation.

The aim of this study was to establish the cutoff points in the Combined Index of Fibromyalgia Severity (ICAF) questionnaire which allow classification of patients by severity and to evaluate its application in the clinical practice. The cutoff points were calculated using the area under the ROC curve in two cohorts of patients. Three visits, basal, fourth month and 15th month, were considered. The external criterion for grading severity was the number of drugs consumed by the patient. Sequential changes were calculated and compared. Correlations with drug consumption and comparisons of severity between patients with different types of coping were also calculated. Correlation between the number of drugs and the ICAF total score was significant. Three cutoff points were established: absence of Fibromyalgia (FM), <34; mild, 34-41; moderate, 41-50 and severe, >50, with the following distribution of severity: absence in 0.4 %, mild in 18.7 %, moderate in 32.5 % and severe in 48.4 % of the patients. There were significant differences between groups. The treatment under daily clinical conditions showed a significant improvement of the patients which was maintained at the end of follow-up. There was a 17 % reduction in the severe category. The patients with more passive coping factor showed highest punctuations in the remaining scores and were more prevalent in the severe category. The patients with a predominance of the emotional factor showed a better response at the end of follow-up. The established cutoff points allow the classification of FM patients by severity, to know the prognostic and to predict the response to the treatment.

PURPOSE: Contractures are common problems for the elderly with far reaching functional and medical consequences. The aim of this systematic literature review was to give an overview of contracture and to identify potential risk factors associated with contractures. METHODS: A systematic literature search with two objectives limited to the last 10 years was performed to identify studies dealing with definition of contracture (objective 1 = O1) and with risk factors (objective 2 = O2). Predefined information including age, sample size, study design, setting, condition, joint, definition of contracture, mode of measurement, and whether inter- and/or intra-rater reliability were assessed, as well as risk factors of contracture were extracted. RESULTS: One hundred and sixty one and 25 studies were retrieved. After applying exclusion criteria 47 studies (O1) and 3 studies (O2) remained. Only 9 studies (O1) provided a definition of contracture. In 3 studies (O2) several potential risk factors were identified. CONCLUSIONS: In most of the studies it seems that the presence of a contracture is equivalent with the presence of restriction in the range of motion (ROM) of a joint. Very little is known about risk factors for contractures. But it seems that immobility may play a pivotal role in the development of this condition. IMPLICATION FOR REHABILITATION: The prevalence of contractures in nursing home residents is estimated at 55% with significant functional and medical consequences. In most studies, which were published in the last 10 years, the presence of a contracture is equivalent with the presence of restriction in the range of motion of a joint. Immobility seems to play a role in the development of contractures. Potential avenues to prevention of contractures and subsequent functional limitations are exercise programmes for and maintenance of mobility of the elderly.

BACKGROUND: The scheduled update to the German S3 guidelines on fibromyalgia syndrome (FMS) by the Association of the Scientific Medical Societies ("Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften", AWMF; registration number 041/004) was planned starting in March 2011. MATERIALS AND METHODS: The development of the guidelines was coordinated by the German Interdisciplinary Association for Pain Therapy ("Deutsche Interdisziplinären Vereinigung für Schmerztherapie", DIVS), 9 scientific medical societies and 2 patient self-help organizations. Eight working groups with a total of 50 members were evenly balanced in terms of gender, medical field, potential conflicts of interest and hierarchical position in the medical and scientific fields. Literature searches were performed using the Medline, PsycInfo, Scopus and Cochrane Library databases (until December 2010). The grading of the strength of the evidence followed the scheme of the Oxford Centre for Evidence-Based Medicine. The formulation and grading of recommendations was accomplished using a multi-step, formal consensus process. The guidelines were reviewed by the boards of the participating scientific medical societies. RESULTS AND CONCLUSION: The clinical diagnosis of FMS can be established by the American College of Rheumatology (ACR) 1990 classification criteria (with tender point examination), by the modified preliminary diagnostic ACR 2010 criteria or by the diagnostic criteria of the German interdisciplinary guideline (AWMF) on FMS.

BACKGROUND: Interdisciplinary guidelines for the definition, classification and diagnosis of chronic widespread pain (CWP) and fibromyalgia syndrome (FMS) were developed by collaboration of 10 German medical and psychological associations and 2 patient self-help organizations. METHODS: A systematic literature search was performed in the Cochrane Library (1993-12/2006). Medline (1980-2006), and Scopus (1980-12/2006). Levels of evidence were assigned according to the classification system of the Oxford Center for Evidence-Based Medicine. Grading of the strength of recommendation was done according to the German program for disease management guidelines. Standardized procedures to reach a consensus on recommendations were used. RESULTS: CWP is defined by the criteria of the American College of Rheumatology (ACR-strong consensus). FMS can be diagnosed for clinical purposes by symptom-based criteria (without tender point examination) as well as by the ACR criteria (strong consensus).

BACKGROUND: A guideline for the treatment and diagnostic procedures for fibromyalgia syndrome (FMS) was developed in cooperation with 10 German medical and psychological associations and 2 patient self-help groups. METHODS: A systematic literature search including all controlled studies evaluating physiotherapy, exercise and strength training as well as physical therapies was performed in the Cochrane Collaboration Reviews (1993-12/2006), Medline (1980-12/2006), PsychInfo (1966-12/2006) and Scopus (1980-12/2006). Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine. Grading of the strengths of recommendations was done according to the German program for disease management guidelines. Standardized procedures to reach a consensus on recommendations were used. RESULTS: Patient's information at first diagnosis of FMS is strongly recommended (grade A). Patient-centered communication is recommended (grade B). A stepwise treatment approach depending on the adapatation to restrictions in daily life and response to treatment options can be considered (grade C). CONCLUSIONS: The long-term treatment should be based on principles of basic psychosomatic care and shared decision making on treatment options.

BACKGROUND: A guideline for the treatment of fibromyalgia syndrome (FMS) was developed in cooperation with 10 German medical and psychological associations and 2 patient self-help groups. METHODS: A systematic literature search including all controlled studies evaluating multicomponent therapy (MT) was performed in the Cochrane Library (1993-12/2006), Medline (1980-12/2006), PsychInfo (1966-12/2006) and Scopus (1980-12/2006). Levels of evidence were assigned according to the classification system of the Oxford Centre for Evidence-Based Medicine. Grading of the strengths of recommendations was done according to the German program for disease management guidelines. Standardized procedures to reach a consensus on recommendations were used. RESULTS: MT is superior to control groups or routine treatment (evidence level 1A) and should be offered to FMS patients (recommendation strength A). CONCLUSIONS: Future studies should consider medication, other co-therapies and comorbidities. MT programs tailored to FMS subgroups should be tested.

OBJECTIVE: In 1994 the American Academy of Orthopedic Surgeons' outcome research committee developed and validated a functional outcome questionnaire for disabilities of the upper extremity (DASH). The objective of our study was to translate the DASH into German and to evaluate its reliability and validity for German-speaking patients with shoulder pain. METHODS: Translation-backtranslation of the DASH was performed according to published guidelines. Psychometric properties and validity were assessed in 49 consecutive patients with shoulder pain originating from within the shoulder girdle. Age, duration of symptoms and current pain were obtained. Test-retest reliability was assessed in a subset of 18 patients who filled in the questionnaire 10 days later. Internal consistency was evaluated with Cronbach's alpha coefficient. Test-retest reliability was assessed using Spearman correlations and the Bland and Altman plot. To study the validity, we examined the correlation of the DASH with other measures of function of the upper extremity including the HAQ subscales relating to the upper extremity and pain measures (e.g. numerical rating scale, SF-36 pain scale). We also examined our hypothesis that the DASH is moderately correlated with measures of range-of-motion (e.g., forward flexion and abduction). RESULT: Translation-backtranslation revealed no major difficulties. The mean age of the patients was 59 years, mean duration of symptoms 60 months and current pain score 5.6 (NRS). Test-retest reliability was 0.90 for the total DASH. The internal consistency was 0.96. Strong correlations (p<0.01) were found between the DASH and the mean among the five subscales of the HAQ representing upper extremity function (0.88) and pain as measured with the SF-36 bodily pain scale (-0.79). As hypothesized, the DASH was also moderately correlated with measures of range-of-motion (e.g. forward flexion rho=-0.49; abduction rho=-0.57). CONCLUSION: Our data confirm that the German version of the DASH retains the characteristics of the American original and is a reliable and valid instrument to measure functional disability in German speaking patients with shoulder pain.

Fibromyalgia (FM) is a syndrome of unknown etiology characterized by chronic wide spread pain, increased tenderness to palpation and additional symptoms such as disturbed sleep, stiffness, fatigue and psychological distress. While medication mainly focus on pain reduction, physical therapy is aimed at disease consequences such as pain, fatigue, deconditioning, muscle weakness and sleep disturbances and other disease consequences. We systematically reviewed current treatment options in the treatment of fibromyalgia. Based on evidence from randomized controlled trials cardiovascular fitness training importantly improves cardiovascular fitness, both subjective and objective measures of pain as well as subjective energy and work capacity and physical and social activities. Based on anecdotal evidence or small observational studies physiotherapy may reduce overloading of the muscle system, improve postural fatigue and positioning, and condition weak muscles. Modalities and whole body cryotherapy may reduce localized as well as generalized pain in short term. Trigger point injection may reduce pain originating from concomitant trigger points in selected FM patient. Massage may reduce muscle tension and may be prescribed as a adjunct with other therapeutic interventions. Acupuncture may reduce pain and increase pain threshold. Biofeedback may positively influence subjective and objective disease measures. TENS may reduce localized musculoskeletal pain in fibromyalgia. While there seems to be no single best treatment option, physical therapy seem to reduce disease consequences. Accordingly a multidisciplinary approach combining these therapies in a well balanced program may be the most promising strategy and is currently recommended in the treatment of fibromyalgia.

The term "Osteoarthrosis" encompasses a group of joint disorders characterized by pain and restriction of mobility. Currently, considerable confusion prevails with respect to the definition of the disease entity and the classification criteria to be utilized in epidemiologic research. Despite these methodological difficulties, it is discernible from the international rheumatology journals that during the past decade this emerging field of research has become firmly established in several European countries and in North America. Researchers have focused their attention on four major facets of the disease: 1. etiological or risk factors with respect to the initiation and clinical course of disease, 2. the impact of illness on the individual and his family, 3. the statistical estimation of incidence and prevalence rates in the total population or in selected at-risk groups of individuals, 4. health care utilization patterns and their costs and benefits. This survey article aims at providing a critical overview of this emerging field of research, as well as at suggesting to the reader future lines of development useful for public health and health promotion researchers in Germany.
