OBJECTIVES: Many interventions are available to manage chronic pain; understanding the durability of treatment effects may assist with treatment selection. We sought to assess which noninvasive nonpharmacological treatments for selected chronic pain conditions are associated with persistent improvement in function and pain outcomes at least 1 month after the completion of treatment.
DATA SOURCES: Electronic databases (Ovid MEDLINE®, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews) through November 2017, reference lists, and ClinicalTrials.gov.
REVIEW METHODS: Using predefined criteria, we selected randomized controlled trials of noninvasive nonpharmacological treatments for five common chronic pain conditions (chronic low back pain; chronic neck pain; osteoarthritis of the knee, hip, or hand; fibromyalgia; and tension headache) that addressed efficacy or harms compared with usual care, no treatment, waitlist, placebo, or sham intervention; compared with pharmacological therapy; or compared with exercise. Study quality was assessed, data extracted, and results summarized for function and pain. Only trials reporting results for at least 1 month post-intervention were included. We focused on the persistence of effects at short term (1 to <6 months following treatment completion), intermediate term (≥6 to <12 months), and long term (≥12 months).
RESULTS: Two hundred eighteen publications (202 trials) were included. Many included trials were small. Evidence on outcomes beyond 1 year after treatment completion was sparse. Most trials enrolled patients with moderate baseline pain intensity (e.g., >5 on a 0 to 10 point numeric rating scale) and duration of symptoms ranging from 3 months to >15 years. The most common comparison was against usual care. Chronic low back pain: At short term, massage, yoga, and psychological therapies (primarily CBT) (strength of evidence [SOE]: moderate) and exercise, acupuncture, spinal manipulation, and multidisciplinary rehabilitation (SOE: low) were associated with slight improvements in function compared with usual care or inactive controls. Except for spinal manipulation, these interventions also improved pain. Effects on intermediate-term function were sustained for yoga, spinal manipulation, multidisciplinary rehabilitation (SOE: low), and psychological therapies (SOE: moderate). Improvements in pain continued into intermediate term for exercise, massage, and yoga (moderate effect, SOE: low); mindfulness-based stress reduction (small effect, SOE: low); spinal manipulation, psychological therapies, and multidisciplinary rehabilitation (small effects, SOE: moderate). For acupuncture, there was no difference in pain at intermediate term, but a slight improvement at long term (SOE: low). Psychological therapies were associated with slightly greater improvement than usual care or an attention control on both function and pain at short-term, intermediate-term, and long-term followup (SOE: moderate). At short and intermediate term, multidisciplinary rehabilitation slightly improved pain compared with exercise (SOE: moderate). High-intensity multidisciplinary rehabilitation (≥20 hours/week or >80 hours total) was not clearly better than non–high-intensity programs. Chronic neck pain: At short and intermediate terms, acupuncture and Alexander Technique were associated with slightly improved function compared with usual care (both interventions), sham acupuncture, or sham laser (SOE: low), but no improvement in pain was seen at any time (SOE: llow). Short-term low-level laser therapy was associated with moderate improvement in function and pain (SOE: moderate). Combination exercise (any 3 of the following: muscle performance, mobility, muscle re-education, aerobic) demonstrated a slight improvement in pain and function short and long term (SOE: low). Osteoarthritis: For knee osteoarthritis, exercise and ultrasound demonstrated small short-term improvements in function compared with usual care, an attention control, or sham procedure (SOE: moderate for exercise, low for ultrasound), which persisted into the intermediate term only for exercise (SOE: low). Exercise was also associated with moderate improvement in pain (SOE: low). Long term, the small improvement in function seen with exercise persisted, but there was no clear effect on pain (SOE: low). Evidence was sparse on interventions for hip and hand osteoarthritis . Exercise for hip osteoarthritis was associated with slightly greater function and pain improvement than usual care short term (SOE: low). The effect on function was sustained intermediate term (SOE: low). Fibromyalgia: In the short term, acupuncture (SOE: moderate), CBT, tai chi, qigong, and exercise (SOE: low) were associated with slight improvements in function compared with an attention control, sham, no treatment, or usual care. Exercise (SOE: moderate) and CBT improved pain slightly, and tai chi and qigong (SOE: low) improved pain moderately in the short term. At intermediate term for exercise (SOE: moderate), acupuncture, and CBT (SOE: low), slight functional improvements persisted; they were also seen for myofascial release massage and multidisciplinary rehabilitation (SOE: low); pain was improved slightly with multidisciplinary rehabilitation in the intermediate term (SOE: low). In the long term, small improvements in function continued for multidisciplinary rehabilitation but not for exercise or massage (SOE: low for all); massage (SOE: low) improved long-term pain slightly, but no clear impact on pain for exercise (SOE: moderate) or multidisciplinary rehabilitation (SOE: low) was seen. Short-term CBT was associated with a slight improvement in function but not pain compared with pregabalin. Chronic tension headache: Evidence was sparse and the majority of trials were of poor quality. Spinal manipulation slightly improved function and moderately improved pain short term versus usual care, and laser acupuncture was associated with slight pain improvement short term compared with sham (SOE: low). There was no evidence suggesting increased risk for serious treatment-related harms for any of the interventions, although data on harms were limited.
CONCLUSIONS: Exercise, multidisciplinary rehabilitation, acupuncture, CBT, and mind-body practices were most consistently associated with durable slight to moderate improvements in function and pain for specific chronic pain conditions. Our findings provided some support for clinical strategies that focused on use of nonpharmacological therapies for specific chronic pain conditions. Additional comparative research on sustainability of effects beyond the immediate post-treatment period is needed, particularly for conditions other than low back pain.
BACKGROUND: Low back pain (LBP) is responsible for considerable personal suffering worldwide. Those with persistent disabling symptoms also contribute to substantial costs to society via healthcare expenditure and reduced work productivity. While there are many treatment options, none are universally endorsed. The idea that chronic LBP is a condition best understood with reference to an interaction of physical, psychological and social influences, the 'biopsychosocial model', has received increasing acceptance. This has led to the development of multidisciplinary biopsychosocial rehabilitation (MBR) programs that target factors from the different domains, administered by healthcare professionals from different backgrounds.
OBJECTIVES: To review the evidence on the effectiveness of MBR for patients with chronic LBP. The focus was on comparisons with usual care and with physical treatments measuring outcomes of pain, disability and work status, particularly in the long term.
SEARCH METHODS: We searched the CENTRAL, MEDLINE, EMBASE, PsycINFO and CINAHL databases in January and March 2014 together with carrying out handsearches of the reference lists of included and related studies, forward citation tracking of included studies and screening of studies excluded in the previous version of this review.
SELECTION CRITERIA: All studies identified in the searches were screened independently by two review authors; disagreements regarding inclusion were resolved by consensus. The inclusion criteria were published randomised controlled trials (RCTs) that included adults with non-specific LBP of longer than 12 weeks duration; the index intervention targeted at least two of physical, psychological and social or work-related factors; and the index intervention was delivered by clinicians from at least two different professional backgrounds.
DATA COLLECTION AND ANALYSIS: Two review authors extracted and checked information to describe the included studies, assessed risk of bias and performed the analyses. We used the Cochrane risk of bias tool to describe the methodological quality. The primary outcomes were pain, disability and work status, divided into the short, medium and long term. Secondary outcomes were psychological functioning (for example depression, anxiety, catastrophising), healthcare service utilisation, quality of life and adverse events. We categorised the control interventions as usual care, physical treatment, surgery, or wait list for surgery in separate meta-analyses. The first two comparisons formed our primary focus. We performed meta-analyses using random-effects models and assessed the quality of evidence using the GRADE method. We performed sensitivity analyses to assess the influence of the methodological quality, and subgroup analyses to investigate the influence of baseline symptom severity and intervention intensity.
MAIN RESULTS: From 6168 studies identified in the searches, 41 RCTs with a total of 6858 participants were included. Methodological quality ratings ranged from 1 to 9 out 12, and 13 of the 41 included studies were assessed as low risk of bias. Pooled estimates from 16 RCTs provided moderate to low quality evidence that MBR is more effective than usual care in reducing pain and disability, with standardised mean differences (SMDs) in the long term of 0.21 (95% CI 0.04 to 0.37) and 0.23 (95% CI 0.06 to 0.4) respectively. The range across all time points equated to approximately 0.5 to 1.4 units on a 0 to 10 numerical rating scale for pain and 1.4 to 2.5 points on the Roland Morris disability scale (0 to 24). There was moderate to low quality evidence of no difference on work outcomes (odds ratio (OR) at long term 1.04, 95% CI 0.73 to 1.47). Pooled estimates from 19 RCTs provided moderate to low quality evidence that MBR was more effective than physical treatment for pain and disability with SMDs in the long term of 0.51 (95% CI -0.01 to 1.04) and 0.68 (95% CI 0.16 to 1.19) respectively. Across all time points this translated to approximately 0.6 to 1.2 units on the pain scale and 1.2 to 4.0 points on the Roland Morris scale. There was moderate to low quality evidence of an effect on work outcomes (OR at long term 1.87, 95% CI 1.39 to 2.53). There was insufficient evidence to assess whether MBR interventions were associated with more adverse events than usual care or physical interventions.
Sensitivity analyses did not suggest that the pooled estimates were unduly influenced by the results from low quality studies. Subgroup analyses were inconclusive regarding the influence of baseline symptom severity and intervention intensity.
AUTHORS' CONCLUSIONS: Patients with chronic LBP receiving MBR are likely to experience less pain and disability than those receiving usual care or a physical treatment. MBR also has a positive influence on work status compared to physical treatment. Effects are of a modest magnitude and should be balanced against the time and resource requirements of MBR programs. More intensive interventions were not responsible for effects that were substantially different to those of less intensive interventions. While we were not able to determine if symptom intensity at presentation influenced the likelihood of success, it seems appropriate that only those people with indicators of significant psychosocial impact are referred to MBR.

Low back pain (LBP) is a common and disabling disorder in western society. The management of LBP comprises a range of different intervention strategies including surgery, drug therapy, and non-medical interventions. The objective of the present study is to determine the effectiveness of physical and rehabilitation interventions (i.e. exercise therapy, back school, transcutaneous electrical nerve stimulation (TENS), low level laser therapy, education, massage, behavioural treatment, traction, multidisciplinary treatment, lumbar supports, and heat/cold therapy) for chronic LBP. The primary search was conducted in MEDLINE, EMBASE, CINAHL, CENTRAL, and PEDro up to 22 December 2008. Existing Cochrane reviews for the individual interventions were screened for studies fulfilling the inclusion criteria. The search strategy outlined by the Cochrane Back Review Groups (CBRG) was followed. The following were included for selection criteria: (1) randomized controlled trials, (2) adult (≥ 18 years) population with chronic (≥ 12 weeks) non-specific LBP, and (3) evaluation of at least one of the main clinically relevant outcome measures (pain, functional status, perceived recovery, or return to work). Two reviewers independently selected studies and extracted data on study characteristics, risk of bias, and outcomes at short, intermediate, and long-term follow-up. The GRADE approach was used to determine the quality of evidence. In total 83 randomized controlled trials met the inclusion criteria: exercise therapy (n = 37), back school (n = 5), TENS (n = 6), low level laser therapy (n = 3), behavioural treatment (n = 21), patient education (n = 1), traction (n = 1), and multidisciplinary treatment (n = 6). Compared to usual care, exercise therapy improved post-treatment pain intensity and disability, and long-term function. Behavioural treatment was found to be effective in reducing pain intensity at short-term follow-up compared to no treatment/waiting list controls. Finally, multidisciplinary treatment was found to reduce pain intensity and disability at short-term follow-up compared to no treatment/waiting list controls. Overall, the level of evidence was low. Evidence from randomized controlled trials demonstrates that there is low quality evidence for the effectiveness of exercise therapy compared to usual care, there is low evidence for the effectiveness of behavioural therapy compared to no treatment and there is moderate evidence for the effectiveness of a multidisciplinary treatment compared to no treatment and other active treatments at reducing pain at short-term in the treatment of chronic low back pain. Based on the heterogeneity of the populations, interventions, and comparison groups, we conclude that there are insufficient data to draw firm conclusion on the clinical effect of back schools, low-level laser therapy, patient education, massage, traction, superficial heat/cold, and lumbar supports for chronic LBP.
BACKGROUND: Chronic musculoskeletal pain (CMP) is a major health problem, accounting for approximately one-quarter of general practice (GP) consultations in the United Kingdom (UK). Exercise and physical activity is beneficial for the most common types of CMP, such as back and knee pain. However, poor adherence to exercise and physical activity may limit long-term effectiveness. OBJECTIVES: To assess the effects of interventions to improve adherence to exercise and physical activity for people with chronic musculoskeletal pain. SEARCH STRATEGY: We searched the trials registers of relevant Cochrane Review Groups. In addition, we searched the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, CINAHL, AMED, PsycINFO, Science Citation Index and Social Science Citation Index and reference lists of articles to October 2007. We consulted experts for unpublished trials. SELECTION CRITERIA: Randomised or quasi-randomised trials evaluating interventions that aimed to improve adherence to exercise and physical activity in adults with pain for three months and over in the axial skeleton or large peripheral joints. DATA COLLECTION AND ANALYSIS: Two of the four authors independently assessed the quality of each included trial and extracted data. We contacted study authors for missing information. MAIN RESULTS: We included 42 trials with 8243 participants, mainly with osteoarthritis and spinal pain. Methods used for improving and measuring adherence in the included trials were inconsistent. Two of the 17 trials that compared different types of exercise showed positive effects, suggesting that the type of exercise is not an important factor in improving exercise adherence. Six trials studied different methods of delivering exercise, such as supervising exercise sessions, refresher sessions and audio or videotapes of the exercises to take home. Of these, five trials found interventions improved exercise adherence. Four trials evaluated specific interventions targeting exercise adherence; three of these showed a positive effect on exercise adherence. In eight trials studying self-management programmes, six improved adherence measures. One trial found graded activity was more effective than usual care for improving exercise adherence. Cognitive behavioural therapy was effective in a trial in people with whiplash-associated disorder, but not in trials of people with other CMP. In the trials that showed a positive effect on adherence, association between clinical outcomes and exercise adherence was conflicting. AUTHORS' CONCLUSIONS: Interventions such as supervised or individualised exercise therapy and self-management techniques may enhance exercise adherence. However, high-quality, randomised trials with long-term follow up that explicitly address adherence to exercises and physical activity are needed. A standard validated measure of exercise adherence should be used consistently in future studies.
OBJECTIVES: To provide an overview of the effectiveness of multidisciplinary treatments of chronic pain and investigate about their differential effects on outcome in various pain conditions and of different multidisciplinary treatments, settings or durations.
METHODS: In this article, the authors performed a systematic review of all currently available randomized controlled trials (RCTs) fulfilling the inclusion criteria, by using a recently developed rating system aimed to assess the strength of evidence with regard to the methodological quality of the trials.
RESULTS: Compared with other non-disciplinary treatments, moderate evidence of higher effectiveness for multidisciplinary interventions was shown. In contrast to no treatment or standard medical treatment, strong evidence was detected in favour of multidisciplinary treatments. The evidence that comprehensive inpatient programmes were more beneficial that outpatient programmes was moderate. Fibromyalgia and chronic back pain patients tended to profit more substantially than patients with diverse origins or chronic pain diagnoses. No evidence was found that treatment variables, such as duration or programme components, were influential for the success of the intervention.
CONCLUSION: A standard of multidisciplinary programmes should be internationally established to guarantee generally good outcomes in the treatment of chronic pain. Our results highlight the lack of quality of design, execution or reporting of many of the RCTs included in this article. Future studies should more specifically focus on differential effects of treatment components and patient variables, allowing the identification of subgroups, which most probably would profit from multidisciplinary pain programmes.
PURPOSE: To assess the clinical and economic effects of disease management in patients with chronic diseases. METHODS: Electronic databases were searched for English-language articles from 1987 to 2001. Articles were included if they used a systematic approach to care and evaluated patients with chronic disease, reported objective measurements of the processes or outcomes of care, and employed acceptable experimental or quasi-experimental study designs as defined by the Cochrane Effective Practice and Organization of Care Group. RESULTS: Two reviewers evaluated 16,917 titles and identified 102 studies that met the inclusion criteria. Identified studies represented 11 chronic conditions: depression, diabetes, rheumatoid arthritis, chronic pain, coronary artery disease, asthma, heart failure, back pain, chronic obstructive pulmonary disease, hypertension, and hyperlipidemia. Disease management programs for patients with depression had the highest percentage of comparisons (48% [41/86]) showing substantial improvements in patient care, whereas programs for patients with chronic obstructive pulmonary disease (9% [2/22]) or chronic pain (8% [1/12]) appeared to be the least effective. Of the outcomes more frequently studied, disease management appeared to improve patient satisfaction (71% [12/17]), patient adherence (47% [17/36]), and disease control (45% [33/74]) most commonly and cost-related outcomes least frequently (11% to 16%). CONCLUSION: Disease management programs were associated with marked improvements in many different processes and outcomes of care. Few studies demonstrated a notable reduction in costs. Further research is needed to understand how disease management can most effectively improve the quality and cost of care for patients with chronic diseases.
BACKGROUND: Since the introduction of the Swedish back school in 1969, back schools have frequently been used for treating patients with low-back pain (LBP). However, the content of back schools has changed and appears to vary widely today.
OBJECTIVES: To assess the effectiveness of back schools for patients with non-specific LBP.
SEARCH STRATEGY: We searched the MEDLINE and EMBASE databases and the Cochrane Central Register of Controlled Trials to May 2003 for relevant trials reported in English, Dutch, French or German. We also screened references from relevant reviews and included trials. The literature search has now been updated to November 2004. No additional trials were identified.
SELECTION CRITERIA: Randomized controlled trials (RCTs) that reported on any type of back school for non-specific LBP were included.
DATA COLLECTION AND ANALYSIS: Four reviewer authors, blinded to authors, institution and journal, independently extracted the data and assessed the quality of the trials. We set the high quality level, a priori, at a trial meeting six or more of 11 internal validity criteria. As data were clinically and statistically too heterogeneous to perform a meta-analysis, we used a qualitative review (best evidence synthesis) to summarize the results. The evidence was classified into four levels (strong, moderate, limited or no evidence), taking into account the methodological quality of the studies. We also evaluated the clinical relevance of the studies.
MAIN RESULTS: Nineteen RCTs (3584 patients) were included in this updated review. Overall, the methodological quality was low, with only six trials considered to be high quality. It was not possible to perform relevant subgroup analyses for LBP with radiation versus LBP without radiation. The results indicate that there is moderate evidence suggesting that back schools have better short and intermediate-term effects on pain and functional status than other treatments for patients with recurrent and chronic LBP. There is moderate evidence suggesting that back schools for chronic LBP in an occupational setting, are more effective than other treatments and placebo or waiting list controls on pain, functional status and return to work during short and intermediate-term follow-up. In general, the clinical relevance of the studies was rated as insufficient.
AUTHORS' CONCLUSIONS: There is moderate evidence suggesting that back schools, in an occupational setting, reduce pain, and improve function and return-to-work status, in the short and intermediate-term, compared to exercises, manipulation, myofascial therapy, advice, placebo or waiting list controls, for patients with chronic and recurrent LBP. However, future trials should improve methodological quality and clinical relevance and evaluate the cost-effectiveness of back schools.
OBJECTIVE: To carry out a systematic review of the literature examining the efficacy of psychological interventions (e.g., relaxation, biofeedback, cognitive-behavioral therapy) in the treatment of rheumatoid arthritis (RA).
METHODS: Studies that met the following criteria were included: random assignment, wait-list or usual care control condition; publication in peer-reviewed journals; treatment that included some psychological component beyond simply providing education information; and separate data provided for patients with RA if subjects with conditions other than RA were included. Two investigators independently extracted data on study design, sample size and characteristics, type of intervention, type of control, direction and nature of the outcome(s).
RESULTS: Twenty-five trials met the inclusion criteria. Methodologic quality was assessed, and effect sizes were calculated for 6 outcomes. Significant pooled effect sizes were found postintervention for pain (0.22), functional disability (0.27), psychological status (0.15), coping (0.46), and self efficacy (0.35). At followup (averaging 8.5 months), significant pooled effect sizes were observed for tender joints (0.33), psychological status (0.30), and coping (0.52). No clear or consistent patterns emerged when effect sizes for different types of treatment and control conditions were compared, or when higher quality trials were compared to lower quality ones. Findings do, however, suggest that these psychological interventions may be more effective for patients who have had the illness for shorter duration.
CONCLUSIONS: Despite some methodologic flaws in the literature, psychological interventions may be important adjunctive therapies in the medical management of RA.
OBJECTIVE: To systematically evaluate the published evidence regarding the characteristics and effectiveness of disease management programmes. DESIGN: Meta-analysis. DATA SOURCES: Computerised databases for English language articles during 1987-2001. Study selection: 102 articles evaluating 118 disease management programmes. MAIN OUTCOME MEASURES: Pooled effect sizes calculated with a random effects model. RESULTS: Patient education was the most commonly used intervention (92/118 programmes), followed by education of healthcare providers (47/118) and provider feedback (32/118). Most programmes (70/118) used more than one intervention. Provider education, feedback, and reminders were associated with significant improvements in provider adherence to guidelines (effect sizes (95% confidence intervals) 0.44 (0.19 to 0.68), 0.61 (0.28 to 0.93), and 0.52 (0.35 to 0.69) respectively) and with significant improvements in patient disease control (effect sizes 0.35 (0.19 to 0.51), 0.17 (0.10 to 0.25), and 0.22 (0.1 to 0.37) respectively). Patient education, reminders, and financial incentives were all associated with improvements in patient disease control (effect sizes 0.24 (0.07 to 0.40), 0.27 (0.17 to 0.36), and 0.40 (0.26 to 0.54) respectively). CONCLUSIONS: All studied interventions were associated with improvements in provider adherence to practice guidelines and disease control. The type and number of interventions varied greatly, and future studies should directly compare different types of intervention to find the most effective.
Many interventions are available to manage chronic pain; understanding the durability of treatment effects may assist with treatment selection. We sought to assess which noninvasive nonpharmacological treatments for selected chronic pain conditions are associated with persistent improvement in function and pain outcomes at least 1 month after the completion of treatment.
DATA SOURCES:
Electronic databases (Ovid MEDLINE®, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews) through November 2017, reference lists, and ClinicalTrials.gov.
REVIEW METHODS:
Using predefined criteria, we selected randomized controlled trials of noninvasive nonpharmacological treatments for five common chronic pain conditions (chronic low back pain; chronic neck pain; osteoarthritis of the knee, hip, or hand; fibromyalgia; and tension headache) that addressed efficacy or harms compared with usual care, no treatment, waitlist, placebo, or sham intervention; compared with pharmacological therapy; or compared with exercise. Study quality was assessed, data extracted, and results summarized for function and pain. Only trials reporting results for at least 1 month post-intervention were included. We focused on the persistence of effects at short term (1 to <6 months following treatment completion), intermediate term (≥6 to <12 months), and long term (≥12 months).
RESULTS:
Two hundred eighteen publications (202 trials) were included. Many included trials were small. Evidence on outcomes beyond 1 year after treatment completion was sparse. Most trials enrolled patients with moderate baseline pain intensity (e.g., >5 on a 0 to 10 point numeric rating scale) and duration of symptoms ranging from 3 months to >15 years. The most common comparison was against usual care. Chronic low back pain: At short term, massage, yoga, and psychological therapies (primarily CBT) (strength of evidence [SOE]: moderate) and exercise, acupuncture, spinal manipulation, and multidisciplinary rehabilitation (
SOE:

SOE:
moderate). Improvements in pain continued into intermediate term for exercise, massage, and yoga (moderate effect
low); spinal manipulation, psychological therapies, and multidisciplinary rehabilitation (small effects
, SOE:
moderate). For acupuncture, there was no difference in pain at intermediate term, but a slight improvement at long term (
SOE:
low). Psychological therapies were associated with slightly greater improvement than usual care or an attention control on both function and pain at short-term, intermediate-term, and long-term followup (
SOE:
moderate). At short and intermediate term, multidisciplinary rehabilitation slightly improved pain compared with exercise (
SOE:
moderate). High-intensity multidisciplinary rehabilitation (≥20 hours/week or >80 hours total) was not clearly better than non–high-intensity programs. Chronic neck pain: At short and intermediate terms, acupuncture and Alexander Technique were associated with slightly improved function compared with usual care (both interventions), sham acupuncture, or sham laser (
SOE:
low), but no improvement in pain was seen at any time (
SOE:

SOE:
moderate). Combination exercise (any 3 of the following: muscle performance, mobility, muscle re-education, aerobic) demonstrated a slight improvement in pain and function short and long term (
SOE:
low). Osteoarthritis: For knee osteoarthritis, exercise and ultrasound demonstrated small short-term improvements in function compared with usual care, an attention control, or sham procedure (
SOE:
moderate for exercise, low for ultrasound), which persisted into the intermediate term only for exercise (
SOE:
low). Exercise was also associated with moderate improvement in pain (
SOE:
low). Long term, the small improvement in function seen with exercise persisted, but there was no clear effect on pain (
SOE:
low). Evidence was sparse on interventions for hip and hand osteoarthritis . Exercise for hip osteoarthritis was associated with slightly greater function and pain improvement than usual care short term (
SOE:
low). The effect on function was sustained intermediate term (
SOE:
low). Fibromyalgia: In the short term, acupuncture (
SOE:
moderate), CBT, tai chi, qigong, and exercise (
SOE:
low) were associated with slight improvements in function compared with an attention control, sham, no treatment, or usual care. Exercise (
SOE:
moderate) and CBT improved pain slightly, and tai chi and qigong (
SOE:
low) improved pain moderately in the short term. At intermediate term for exercise (
SOE:
moderate), acupuncture, and CBT (
SOE:
low), slight functional improvements persisted; they were also seen for myofascial release massage and multidisciplinary rehabilitation (
SOE:
low); pain was improved slightly with multidisciplinary rehabilitation in the intermediate term (
SOE:
low). In the long term, small improvements in function continued for multidisciplinary rehabilitation but not for exercise or massage (
SOE:
low for all); massage (
SOE:
low) improved long-term pain slightly, but no clear impact on pain for exercise (
SOE:
moderate) or multidisciplinary rehabilitation (
SOE:
low) was seen. Short-term CBT was associated with a slight improvement in function but not pain compared with pregabalin. Chronic tension headache: Evidence was sparse and the majority of trials were of poor quality. Spinal manipulation slightly improved function and moderately improved pain short term versus usual care, and laser acupuncture was associated with slight pain improvement short term compared with sham (
SOE:
low). There was no evidence suggesting increased risk for serious treatment-related harms for any of the interventions, although data on harms were limited.
CONCLUSIONS:
Exercise, multidisciplinary rehabilitation, acupuncture, CBT, and mind-body practices were most consistently associated with durable slight to moderate improvements in function and pain for specific chronic pain conditions. Our findings provided some support for clinical strategies that focused on use of nonpharmacological therapies for specific chronic pain conditions. Additional comparative research on sustainability of effects beyond the immediate post-treatment period is needed, particularly for conditions other than low back pain.
