OBJECTIVES
To evaluate the evidence for the effectiveness and cost-effectiveness of the newer diagnostic imaging tests as an addition to clinical examination and patient history for the diagnosis of soft tissue shoulder disorders.


DATA SOURCES
Literature was identified from several sources including general medical databases.


REVIEW METHODS
Studies were identified that evaluated clinical examination, ultrasound, magnetic resonance imaging (MRI), or magnetic resonance arthrography (MRA) in patients suspected of having soft tissue shoulder disorders. Outcomes assessed were clinical impingement syndrome or rotator cuff tear (full, partial or any). Only cohort studies were included. The methodological quality of included test accuracy studies was assessed using a formal quality assessment tool for diagnostic studies and the extraction of study findings was conducted in duplicate using a pre-designed and piloted data extraction form to avoid any errors. For each test, sensitivity, specificity and positive and negative likelihood ratios with 95% confidence intervals were calculated for each study. Where possible pooled estimates of sensitivity, specificity and likelihood ratios were calculated using random effects methods. Potential sources of heterogeneity were investigated by conducting subgroup analyses.


RESULTS
In the included studies, the prevalence of rotator cuff disorders was generally high, partial verification of patients was common and in many cases patients who were selected retrospectively because they had undergone the reference test. Sample sizes were generally very small. Reference tests were often inappropriate with many studies using arthrography alone, despite problems with its sensitivity. For clinical assessment, 10 cohort studies were found that examined either the accuracy of individual tests or clinical examination as a whole: individual tests were either good at ruling out rotator cuff tears when negative (high sensitivity) or at ruling in such disorders when positive (high specificity), but small sample sizes meant that there was no conclusive evidence. Ultrasound was investigated in 38 cohort studies and found to be most accurate when used for the detection of full-thickness tears; sensitivity was lower for detection of partial-thickness tears. For MRI, 29 cohort studies were included. For full-thickness tears, overall pooled sensitivities and specificities were fairly high and the studies were not statistically heterogeneous; however for the detection of partial-thickness rotator cuff tears, the pooled sensitivity estimate was much lower. The results from six MRA studies suggested that it may be very accurate for detection of full-thickness rotator cuff tears, although its performance for the detection of partial-thickness tears was less consistent. Direct evidence for the performance of one test compared with another is very limited.


CONCLUSIONS
The results suggest that clinical examination by specialists can rule out the presence of a rotator cuff tear, and that either MRI or ultrasound could equally be used for detection of full-thickness rotator cuff tears, although ultrasound may be better at picking up partial tears. Ultrasound also may be more cost-effective in a specialist hospital setting for identification of full-thickness tears. Further research suggestions include the need for large, well-designed, prospective studies of the diagnosis of shoulder pain, in particular a follow-up study of patients with shoulder pain in primary care and a prospective cohort study of clinical examination, ultrasound and MRI, alone and/or in combination.

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 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.

Noninvasive Nonpharmacological Treatment for Chronic Pain: A Systematic Review

Thanks to advances in neuroscience, biopsychosocial models for diagnostics and treatment (including physical, psychological, and pharmacological therapies) currently have more clinical support and scientific growth. At present, a conservative treatment approach prevails over surgery, given it is less aggressive and usually results in satisfactory clinical outcomes in mild-moderate temporomandibular disorder (TMD). The aim of this review is to evaluate the recent evidence, identify challenges, and propose solutions from a clinical point of view for patients with craniofacial pain and TMD. The treatment we propose is structured in a multi-modal approach based on a biobehavioral approach that includes medical, physiotherapeutic, psychological, and dental treatments. We also propose a new biobehavioral model regarding pain perception and motor behavior for the diagnosis and treatment of patients with painful TMD.

Management of pain in patients with temporomandibular disorder (TMD): challenges and solutions.

We explored the use of virtual reality distraction techniques for use as adjunctive therapy to treat chronic pain. Virtual environments were specifically created to provide pleasant and engaging experiences where patients navigated on their own through rich and varied simulated worlds. Real-time physiological monitoring was used as a guide to determine the effectiveness and sustainability of this intervention. Human factors studies showed that virtual navigation is a safe and effective method for use with chronic pain patients. Chronic pain patients demonstrated significant relief in subjective ratings of pain that corresponded to objective measurements in peripheral, noninvasive physiological measures.

The Effect of Neck Pain on Cervical Kinematics, as Assessed in a Virtual Environment

To evaluate short- and intermediate-term effects of kinematic training (KT) using virtual reality (VR) or laser in patients with chronic neck pain. A randomised controlled trial with three arms (laser, VR, control) to post-intervention (N = 90), and two arms (laser or VR) continuing to 3 months follow-up. Home training intervention was provided during 4 weeks to VR and laser groups while control group waited. Primary outcome measures included neck disability index (NDI), global perceived effect (GPE), and cervical motion velocity (mean and peak). Secondary outcome measures included pain intensity (VAS), health status (EQ5D), kinesiophobia (TSK), range, smoothness, and accuracy of neck motion as measured by the neck VR system. Measures were taken at baseline, immediately post-training, and 3 months later. Ninety patients with neck pain were randomised to the trial, of which 76 completed 1 month follow-up, and 56 the 3 months follow-up. Significant improvements were demonstrated in NDI and velocity with good effect sizes in intervention groups compared to control. No within-group changes were presented in the control group, compared to global improvements in intervention groups. Velocity significantly improved at both time points in both groups. NDI, VAS, EQ5D, TSK and accuracy significantly improved at both time points in VR and in laser at 3 months evaluation in all but TSK. GPE scores showed 74–84% of participants perceived improvement and/or were satisfied. Significant advantages to the VR group compared to laser were found in velocity, pain intensity, health status and accuracy at both time points. The results support home kinematic training using VR or laser for improving disability, neck pain and kinematics in the short and intermediate term with an advantage to the VR group. The results provide directions for future research, use and development. ACTRN12615000231549.

Remote kinematic training for patients with chronic neck pain: a randomised controlled trial.

Background and Purpose
The use of virtual reality (VR) for assessment and intervention of neck pain has previously been used and shown reliable for cervical range of motion measures. Neck VR enables analysis of task-oriented neck movement by stimulating responsive movements to external stimuli. Therefore, the purpose of this study was to establish inter-tester reliability of neck kinematic measures so that it can be used as a reliable assessment and treatment tool between clinicians.

Neck motion kinematics: an inter-tester reliability study using an interactive neck VR assessment in asymptomatic individuals

Purpose: To evaluate the velocity, smoothness, and symmetry of fast cervical motion in asymptomatic individuals of four age groups, and to investigate the relationship between age and these measures. Methods: Cross-sectional study with fifty-eight asymptomatic volunteers (28 F, 30 M), aged 18-80 (mean age=44.14 ± 17.35) were assessed using a customized Virtual Reality (VR) system. VR head-mounted display stimulated fast neck movements in response to virtual targets appearing randomly. Outcome measures were neck motion velocity, smoothness, and symmetry of velocity profile. Main findings: The eldest group differed from younger age groups in peak and mean velocity of neck motion. Smoothness demonstrated age-group difference only between the youngest and oldest groups. Linear regression analysis showed significant negative correlations in mean and peak velocity, and in smoothness with age, excluding smoothness in right rotation. No age-group differences and no significant correlations were found for time-to-peakvelocity in all directions of neck movement (p>0.05). Conclusion: This study showed that age influenced the velocity in which asymptomatic individuals could move their neck, specifically in elders over 60 years of age. Clinically, this may suggest that when elders with neck pain present with slower cervical motion, it is probably partly due to aging and thus should be taken into account in the management and expected level of performance.
