    Input: Objectives : To assess the effectiveness of multidisciplinary rehabilitation in the treatment of fibromyalgia in comparison to st and ard medical care . Methods : Seventy-nine men and women were r and omly assigned to one of two groups . The intervention group consisted of a rheumatologist and physical therapist intake and discharge , 18 group supervised exercise therapy sessions , 2 group pain and stress management lectures , 1 group education lecture , 1 group dietary lecture , and 2 massage therapy sessions . The control group consisted of st and ard medical care with the patients ' family physician . Outcome measures included self-perceived health status , pain-related disability , average pain intensity , depressed mood , days in pain , hours in pain , prescription and nonprescription medication usage , and work status . Outcomes were measured at the end of the 6-week intervention and at 15-month follow-up . Results : Thirty-five out of 43 patients from the intervention group and 36 out of 36 patients from the control group completed the study . There were no statistically significant differences between the 2 groups prior to intervention . Intention-to-treat analysis revealed that the intervention group , in comparison to the control group , experienced statistically significant changes at intervention completion in self-perceived health status , average pain intensity , pain related disability , depressed mood , days in pain , and hours in pain , but no significant differences in nonprescription drug use , prescription drug use , or work status . At 15 months , all health outcomes retained their significance except health status . Nonprescription and prescription drug use demonstrated significant reductions at 15 months . Binary logistic regression indicated that long-term changes in Pain Disability Index were influenced by long-term exercise adherence and income status . Conclusions : Positive health-related outcomes in this mostly unresponsive condition can be obtained with a low-cost , group multidisciplinary intervention in a community-based , non clinical setting Background Massage is increasingly used to manage  chronic pain  but its benefit has not been clearly established . The aim of the study is to determine the effectiveness of a single session of nurse-administered massage for the short term relief of  chronic non-malignant pain and anxiety . Methods A r and omised controlled trial design was used , in which the patients were assigned to a massage or control group . The massage group received a 15 minute manual massage and the control group a 15 minute visit to talk about their pain .  Adult patients attending a pain relief unit with a diagnosis of chronic pain whose pain was described as moderate or severe were eligible for the study . An observer blind to the patients ' treatment group carried out assessment s immediately before ( baseline ) , after treatment and 1 , 2 , 3 and 4 hours later . Pain was assessed using 100 mm visual analogue scale and the McGill Pain Question naire . Pain Relief was assessed using a five point verbal rating scale . Anxiety was assessed with the Spielberger short form State-Trait Anxiety Inventory . Results 101 patients were r and omised and evaluated , 50 in the massage and 51 in the control group . There were no statistically significant differences between the groups at baseline interview . Patients in the massage but not the control group had significantly less pain compared to baseline immediately after and one hour post treatment . 95 % confidence interval for the difference in mean pain reduction at one hour post treatment between the massage and control groups is 5.47 mm to 24.70 mm . Patients in the massage but not the control group had a statistically significant reduction in anxiety compared to baseline immediately after and at 1 hour post treatment . Conclusion Massage is effective in the short term for chronic pain of moderate to severe intensity . Trial Registration [ IS RCT N98406653 To evaluate the impact of music on opioid requirements and pain levels during  renal lithotripsy  using alfentanil patient-controlled analgesia ( PCA ) , we conducted a prospect i ve , blinded , r and omized controlled trial . Patients undergoing lithotripsy were instructed in PCA use and asked to rate their anxiety and select their preferred type of music . They were then premedicated with morphine and ketorolac and r and omly allocated into two groups . Group 1 ( n = 97 ) had music started 10 min before the procedure and maintained until 10 min after its conclusion . Group 2 ( n = 96 ) had music begun at the conclusion of lithotripsy and continued for 10 min . Pain intensity , alfentanil requirement , side effects , quality of analgesia , patient satisfaction , and acceptance of the technique were evaluated . Demographics , alfentanil requirement , pain levels , side effects , quality of analgesia , and patient satisfaction were similar in both groups . The addition of music did not provide any benefit . This result raises the possibility that some nonpharmacologic therapies have minimal impact in setting s where the painful stimulus is moderate to severe and adequate pharmacotherapy is available OBJECTIVE Studies have suggested that the Arthritis Self-Management Program ( ASMP ) course is effective at reducing arthritis pain and health care costs  in volunteer participants . There have been no reports of trials of the ASMP in the context of primary care physicians ' practice s , where the potential for spreading the program may be greatest . We conducted a r and omized controlled trial of the ASMP course in a large primary care physician network . METHODS Patients with osteoarthritis , rheumatoid arthritis , or fibromyalgia were recruited for the study . Subjects in the intervention practice s received the 6 week course and those in the control practice s received only the ASMP book , without course .  Disability , pain , self-efficacy , mental health , and satisfaction were measured using vali date d instruments at baseline and at 4 months . RESULTS One hundred thirteen patients were recruited for the ASMP course  ( intervention ) and completed baseline and 4 month followup question naires . Eighty-four percent completed at least 4 of 6 classes . Seventy-four patients received the ASMP manual ( controls ) and completed both question naires . Patients in the intervention and control groups had similar baseline pain ( p = 0.94 ) , self-efficacy to control pain ( p = 0.90 ) , mental health ( p = 0.10 ) , and vitality scores ( p = 0.21 ) , but those in the intervention arm had slightly less disability ( p = 0.04 ) . At 4 months , there was no significant improvement from baseline in any endpoint and no difference between patients in the intervention and control groups ( all p > 0.2 ) . Patient satisfaction with arthritis care and outcomes was no different for intervention and control patients ( all p > 0.3 ) . All types of health care re source use were similar at baseline and followup for both intervention and control groups ( all p > 0.2 ) . CONCLUSION While the ASMP course has been found to be effective in other patient groups , there were no significant clinical benefits noted at 4 months in patients recruited from primary care practice Objective To determine the effectiveness of lessons in the Alex and er technique , massage therapy , and advice from a doctor to take exercise ( exercise prescription ) along with nurse delivered behavioural counselling for patients with chronic or recurrent back pain . Design Factorial r and omised trial . Setting 64 general practice s in Engl and . Participants 579 patients with chronic or recurrent low back pain ; 144 were r and omised to normal care , 147 to massage , 144 to six Alex and er technique lessons , and 144 to 24 Alex and er technique lessons ;  half of each of these groups were r and omised to exercise prescription . Interventions Normal care ( control ) , six sessions of massage , six or 24 lessons on the Alex and er technique , and prescription for exercise from a doctor with nurse delivered behavioural counselling . Main outcome measures Rol and Morris disability score ( number of activities impaired by pain ) and number of days in pain . Results Exercise and lessons in the Alex and er technique , but not massage , remained effective at one year ( compared with control Rol and disability score 8.1 : massage −0.58 , 95 % confidence interval −1.94 to 0.77 , six lessons −1.40 , −2.77 to −0.03 , 24 lessons −3.4 , −4.76 to −2.03 , and exercise −1.29 , −2.25 to −0.34 ) . Exercise after six lessons achieved 72 % of the effect of 24 lessons alone ( Rol and disability score −2.98 and −4.14 , respectively ) . Number of days with back pain in the past four weeks was lower after lessons ( compared with control median 21 days : 24 lessons −18 , six lessons −10 , massage −7 ) and quality of life improved significantly . No significant harms were reported . Conclusions One to one lessons in the Alex and er technique from registered teachers have long term benefits for patients with chronic back pain . Six lessons followed by exercise prescription were nearly as effective as 24 lessons . Trial registration National Research Register N0028108728 . How does the Alex and er Technique work ?

A cognitive-behavioral pain management program for elderly nursing home residents with chronic pain was compared with an attention/support control treatment in a r and omized pre-/post-comparison group design with follow-up . Thirteen women and nine men , ranging in age from 61 to 98 ( M = 77.2 ) , from two large nursing homes participated in the treatment programs through 10 weekly group sessions . Results revealed that the subjects who received the cognitive-behavioral training reported less pain and pain-related disability , although the two programs were perceived as equally credible both before and after treatment . No significant treatment effects were found for depression and physician medication ratings . Treatment effects were maintained at 4-month follow-up , despite an overall increase in reported pain . Findings indicate that elderly nursing home residents with chronic pain and without serious cognitive impairment can benefit substantially from training in cognitive and behavioral pain management strategies that are known to be effective with younger age groups and the community-resident elderly population OBJECTIVE To determine if the chronic pain frequently presented by postpolio patients can be relieved by application of magnetic fields applied directly over an identified pain trigger point . DESIGN Double-blind r and omized clinical trial . SETTING The postpolio clinic of a large rehabilitation hospital . PATIENTS Fifty patients with diagnosed postpolio syndrome who reported muscular or arthritic-like pain . INTERVENTION Application of active or placebo 300 to 500 Gauss magnetic devices to the affected area for 45 minutes . MAIN OUTCOME MEASURE Score on the McGill Pain Question naire . RESULTS Patients who received the active device experienced an average pain score decrease of 4.4 + /- 3.1 ( p < .0001 ) on a 10-point scale . Those with the placebo devices experienced a decrease of 1.1 + /- 1.6 points ( p < .005 ) . The proportion of patients in the active-device group who reported a pain score decrease greater than the average placebo effect was 76 % , compared with 19 % in the placebo-device group ( p < .0001 ) . CONCLUSIONS The application of a device delivering static magnetic fields of 300 to 500 Gauss over a pain trigger point results in significant and prompt relief of pain in postpolio subjects BACKGROUND Chronic pain is recognised as an important problem in the community but our underst and ing of the epidemiology of chronic pain remains limited . We undertook a study design ed to quantify and describe the prevalence and distribution of chronic pain in the community . METHODS A r and om sample of 5036 patients , aged 25 and over , was drawn from 29 general practice s in the Grampian region of the UK and surveyed by a postal self-completion question naire . The question naire included case-screening questions , a question on the cause of the pain , the chronic pain grade question naire , the level of expressed needs question naire , and sociodemographic questions . FINDINGS 3605 question naires were returned completed . 1817 ( 50.4 % ) of patients self reported chronic pain , equivalent to 46.5 % of the general population . 576 reported back pain and 570 reported arthritis ; these were the most common complaints and accounted for a third of all complaints . Backward stepwise logistic-regression modelling identified age , sex , housing tenure , and employment status as significant predictors of the presence of chronic pain in the community . 703 ( 48.7 % ) individuals with chronic pain had the least severe grade of pain , and 228 ( 15.8 % ) the most severe grade . Of those who reported chronic pain , 312 ( 17.2 % ) reported no expressed need , and 509 ( 28.0 % ) reported the highest expressed need . INTERPRETATION Chronic pain is a major problem in the community and certain groups within the population are more likely to have chronic pain . A detailed underst and ing of the epidemiology of chronic pain is essential for efficient management of chronic pain in primary care Objective : To evaluate the efficacy of a treatment programme for patients with fibromyalgia ( FM ) based on self management , using pool exercises and education . Methods : R and omised controlled trial with a 6 month follow up to evaluate an outpatient multidisciplinary programme ; 164 patients with FM were allocated to an immediate 6 week programme ( n = 84 ) or to a waiting list control group ( n = 80 ) . The main outcomes were changes in quality of life , functional consequences , patient satisfaction and pain , using a combination of patient question naires and clinical examinations . The question naires included the Fibromyalgia Impact Question naire ( FIQ ) , Psychological General Well-Being ( PGWB ) index , regional pain score diagrams , and patient satisfaction measures . Results : 61 participants in the treatment group and 68 controls completed the programme and 
    Output:
    
In the end , eight controlled trials were included The main results were : • Cognitive-behavioural and sensorial stimulation programs  reduce perceived chronic pain .
• Interventions based on psycho-education and music therapy programs  reduce osteoarticular pain .
• Magnetic therapy and guided imagery are interventions that may relieve chronic headache .
• An intervention including a physical exercise program in incontinent elderly  increases mobility but does not relieve pain , and may even worsen it .
Other outcome measures showed an improvement in the quality of life ( sensorial stimulation and guided imagery ) , in depression , disability and empowerment ( music therapy ) and physical functioning ( program of psycho-education ) .
