Is exercise effective for the management of neck pain and associated disorders or whiplash-associated disorders? A systematic review by the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

The quality of reporting in randomized controlled trials investigating exercise for individuals with whiplash-associated disorders; a systematic review

BACKGROUND

Whiplash-associated disorders are a common sequela of road traffic accidents. Exercise therapy is considered an effective intervention, and it is recommended for the management of such condition. However, the application of research findings to everyday clinical practice is dependent on sufficient details being reported.

OBJECTIVES

To explore the quality of reporting in studies investigating the effectiveness of exercise for whiplash-associated disorders.

METHODS

A literature search was conducted to identify studies testing the effectiveness of exercise for whiplash-associated disorders. Two reporting checklists were used to evaluate reporting completeness. The median positive scores for each study and overall percentage of positive scores for each item were calculated. Percentage agreement and the Cohen's Kappa coefficient were calculated.

RESULTS

Twenty-one studies were included. According to the Template for Intervention Description and Replication checklist, items were reported appropriately with a median of 29% (range 0-95%, IQR 40.5). The median number of adequately reported items per study was 5 (range 1-10, IQR 3). For the Consensus on Exercise Reporting Template checklist, items were reported appropriately with a median of 29% (range 0-57%, IQR 29). The median number of adequately reported items per study was 4 (range 0-16, IQR 8). Percentage agreement ranged from 57% to 100% while Cohen's Kappa from -0.17 to 1.00.

CONCLUSIONS

The study reveals significant gaps in the quality of reporting in studies investigating exercise for whiplash-associated disorders as both checklists showed a median reporting adequacy of only 29%. Overall, the inter-rater agreement for both checklists was acceptable.

Gray Matter Adaptations to Chronic Pain in People with Whiplash-Associated Disorders are Partially Reversed After Treatment: A Voxel-based Morphometry Study

Gray matter (GM) changes are often observed in people with chronic spinal pain, including those with chronic whiplash-associated disorders (CWAD). These GM adaptations may be reversed with treatment, at least partially. Pain neuroscience education combined with exercise (PNE+Exercise) is an effective treatment, but its neural underlying mechanisms still remain unexplored in CWAD. Here, we performed both cross-sectional and longitudinal voxel-based morphometry to 1) identify potential GM alterations in people with CWAD (n = 63) compared to age- and sex-matched pain-free controls (n = 32), and 2) determine whether these GM alterations might be reversed following PNE+Exercise (compared to conventional physiotherapy). The cross-sectional whole-brain analysis revealed that individuals with CWAD had less GM volume in the right and left dorsolateral prefrontal cortex and left inferior temporal gyrus which was, in turn, associated with higher pain vigilance. Fifty individuals with CWAD and 29 pain-free controls were retained in the longitudinal analysis. GM in the right dorsolateral prefrontal cortex increased after treatment in people with CWAD. Moreover, the longitudinal whole-brain analysis revealed that individuals with CWAD had decreases in GM volumes of the left and right central operculum and supramarginal after treatment. These changes were not specific to treatment modality and some were not observed in pain-free controls over time. Herewith, we provide the first evidence on how GM adaptations to CWAD respond to treatment. PERSPECTIVE: This article presents which gray matter adaptations are present in people with chronic pain after whiplash injuries. Then, we examine the treatment effect on these alterations as well as whether other neuroplastic effects on GM following treatment occur.

Association between clinical biomechanical metrics of cervical spine function and pain or disability in people with neuromusculoskeletal neck pain: Protocol for a systematic review and planned meta-analysis

INTRODUCTION/BACKGROUND

Neck pain is a burdensome condition associated with pain, disability, and economic cost. Neck pain has been associated with observable changes in neuromuscular function and biomechanics. Prior research shows impairments in kinematic control, including reduced mobility, velocity, and smoothness of cervical motion. However, the strength of association between these impairments and patient-reported pain and disability is unclear rendering development of novel and relevant rehabilitation strategies difficult. The aim of this systematic review is to synthesize existing evidence on the strength of association between clinical biomechanical metrics of neck function (ROM, strength, acceleration, accuracy, smoothness, etc.) and patient-reported neck pain and disability.

METHODS/ANALYSIS

This protocol follows Cochrane guidelines and adheres to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P). MEDLINE, EMBASE, CINAHL, SPORTDiscus, Web of Science and Scopus will be searched, along with the gray literature, up to 20 November 2023, using terms and keywords derived from initial scoping searches. Observational studies, including cohorts and cross-sectional studies, that explore associations between clinical biomechanics of the neck and patient-reported outcomes of neck pain or disability will be included. Two reviewers will independently perform study selection, data extraction, and risk of bias assessment (National Institute of Health tool). Data will be synthesized using either a random effects meta-analytic approach or qualitatively using a modified Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach, dependent on the homogeneity of data available.

DISCUSSION AND RELEVANCE

This review addresses a gap in the literature by systematically synthesizing findings on the relationship between neck function impairments and patient-reported outcomes. It will identify priorities for neck pain rehabilitation and gaps in current knowledge.

DISSEMINATION

The results of this review will be disseminated through a peer-reviewed publication, conference presentation, and lay language summaries posted on an open-access website.

Is adding dry needling to a standard care protocol beneficial in patients with chronic neck pain? A randomized placebo-controlled trial

PURPOSE

To evaluate the short-term effects of adding a dry needling therapy to a standard care protocol based on education, exercise and electrotherapy, compared to a sham procedure and to a standard care protocol in isolation in patients with chronic neck pain.

MATERIAL AND METHODS

A randomized placebo-controlled trial was performed. The participants in the dry needling group received a standard care protocol based on patient education, therapeutic exercise and electrotherapy, as well as two sessions of dry needling in the upper trapezius, levator scapulae, and/or sternocleidomastoid muscles. The participants in the sham dry needling group received the same standard care protocol and two sessions of sham dry needling. The participants in the control group received the same standard care protocol. The outcomes measured were pain intensity, pressure pain threshold, neck disability, range of movement, activation of deep cervical flexor muscles, kinesiophobia, pain catastrophizing, anxiety, and depression.

RESULTS

No significant group by time interactions were found for any of the outcome variables except for lower cervical spine range of movement (F = 3.79; p = 0.030).

CONCLUSION

The addition of two sessions of dry needling in the superficial neck muscles to a standard protocol did not yield superior results compared to either the standard care alone or the standard care plus sham dry needling in patients with chronic neck pain in any outcome except for cervical range of movement.

Novel Internet Support for Neck-Specific Rehabilitation Improves Work-Related Outcomes to the Same Extent as Extensive Visits to a Physiotherapy Clinic in Individuals with Chronic Whiplash-Associated Disorders: A Prospective Randomised Study

PURPOSE

To address the current lack of information about work-related factors for individuals with whiplash-associated disorders (WAD) we investigated the effectiveness of 3 months of neck-specific rehabilitation with internet support in combination with four physiotherapy visits (NSEIT) compared to the same exercises performed twice a week (24 times) at a physiotherapy clinic (NSE).

METHODS

This is a prospective, multicentre, randomised controlled trial regarding secondary outcomes of work-related factors in 140 individuals with chronic moderate/severe WAD with 3- and 15-month follow-up.

RESULTS

There were no group differences between NSE and NSEIT in the Work Ability Scale or work subscales of the Neck Disability Index, Whiplash Disability Questionnaire or Fear Avoidance Beliefs Questionnaire (FABQ-work). Both groups improved in all work-related outcome measures, except for FABQ-work after the 3-month intervention and results were maintained at the 15-month follow-up.

CONCLUSIONS

Despite fewer physiotherapy visits for the NSEIT group, there were no group differences between NSEIT and NSE, with improvements in most work-related measures maintained at the 15-month follow-up. The results of the present study are promising for those with remaining work ability problems after a whiplash injury. Protocol registered before data collection started: clinicaltrials.gov NCT03022812.

Exercise Therapy for Chronic Neck Pain: Tailoring Person-Centred Approaches within Contemporary Management

Exercise therapy is considered the best evidence-based approach for managing chronic neck pain. However, the implementation of exercise therapy presents several challenges. Systematic reviews indicate that it has modest effectiveness, while clinical practice guidelines offer limited guidance on the exercise parameters required to optimise clinical outcomes. Moreover, recommendations often fail to differentiate between different types of neck pain. This article addresses the challenges associated with the prescription of exercise for chronic neck pain and provides recommendations for exercise therapy specific to chronic nociceptive, neuropathic, and nociplastic neck pain. The goal of this article is to facilitate the implementation of high-value evidence-based exercise therapy for these distinct types of chronic neck pain with the aim to improve its outcomes and to reduce the related individual and societal burdens.

Patient-reported outcome measures in physical therapy practice for neck pain: an overview of reviews

BACKGROUND

Understanding which patient-reported outcome measures are being collected and utilized in clinical practice and research for patients with neck pain will help to inform recommendations for a core set of measures that provide value to patients and clinicians during diagnosis, clinical decision-making, goal setting and evaluation of responsiveness to treatment. Therefore, the aim of this study was to conduct a review of systematic reviews using a qualitative synthesis on the use of patient-reported outcome measures (PROMs) for patients presenting with neck pain to physical therapy.

METHODS

An electronic search of systematic reviews and guideline publications was performed using MEDLINE (OVID), Embase (Elsevier), CINAHL Complete (EBSCOhost), and Web of Science (Clarivate) databases to identify reviews that evaluated physical therapy interventions or interventions commonly performed by a physical therapist for individuals with neck pain and included at least one patient-reported outcome measure. The frequency and variability in which the outcome measures were reported among the studies in the review and the constructs for which they measured were evaluated. The evaluation of a core set of outcome measures was assessed. Risk of bias and quality assessment was performed using A Measurement Tool to Assess systematic Reviews 2.

RESULTS

Of the initial 7,003 articles, a total of 37 studies were included in the final review. Thirty-one PROMs were represented within the 37 reviews with eleven patient-reported outcome measures in three or more reviews. The eleven PROMs assessed the constructs of disability, pain intensity, psychosocial factors and quality of life. The greatest variability was found amongst individual measures assessing psychosocial factors. Assessment of psychosocial factors was the least represented construct in the included studies. Overall, the most frequently utilized patient reported outcome measures were the Neck Disability Index, Visual Analog Scale, and Numeric Pain Rating Scale. The most frequently used measures evaluating the constructs of disability, pain intensity, quality of life and psychosocial functioning included the Neck Disability Index, Visual Analog Scale, Short-Form-36 health survey and Fear Avoidance Belief Questionnaire respectively. Overall risk of bias and quality assessment confidence levels ranged from critically low (2 studies), low (12 studies), moderate (8 studies), and high (15 studies).

CONCLUSION

This study identified a core set of patient-reported outcome measures that represented the constructs of disability, pain intensity and quality of life. This review recommends the collection and use of the Neck Disability Index and the Numeric Pain Rating Scale or Visual Analog Scale. Recommendation for a QoL measure needs to be considered in the context of available resources and administrative burden. Further research is needed to confidently recommend a QoL and psychosocial measure for patients presenting with neck pain. Other measures that were not included in this review but should be further evaluated for patients with neck pain are the Patient Reported Outcomes Measurement Information System (PROMIS) Physical function, PROMIS Pain Interference and the Optimal Screening for Prediction of Referral and Outcome Yellow Flag (OSPRO-YF) tool.

Baseline Depressive Symptoms Do Not Moderate the Association Between Baseline Symptom Severity and Time to Recovery in Individuals with Grade I-II Whiplash-Associated Disorders: A Secondary Analysis of a Randomized Controlled Trial

OBJECTIVE

This study investigated the moderating role of baseline depressive symptoms on the association between baseline pain severity and time to recovery in individuals with acute grade I-II whiplash-associated disorders.

DESIGN

This is a secondary analysis of a randomized controlled trial investigating the effectiveness of a government-regulated rehabilitation guideline for the management of grade I-II whiplash-associated disorders. Participants who completed baseline questionnaires for neck pain intensity and depressive symptoms and follow-up questionnaire on self-reported recovery were included in the analysis. Cox proportional hazards models were built, and hazard rate ratios were reported to describe the association between baseline neck pain intensity and time to self-reported recovery and to assess the effect modification of baseline depressive symptoms.

RESULTS

Three hundred three participants provided data for this study. Despite baseline level of depressive symptoms and neck pain intensity being independently associated with delayed recovery, the association between baseline neck pain intensity and time to recovery was not stronger for individuals with significant postcollision depressive symptoms (hazard rate ratio = 0.91; 95% confidence interval = 0.79-1.04) than for those without depressive symptoms (hazard rate ratio = 0.92; 95% confidence interval = 0.83-1.02).

CONCLUSIONS

Baseline depressive symptoms are not an effect modifier of the association between baseline neck pain intensity and time to self-reported recovery in acute whiplash-associated disorders.

Feasibility and effectiveness of telehealth in the management of cervicothoracic and lumbar pain during the first six months of the SARS-CoV-2 pandemic: A case series

Objectives

The primary study objective is to assess the effectiveness and utility of telehealth in managing spine pain. The secondary objective is to evaluate the feasibility of employing various treatments utilizing telehealth.

Study design

Retrospective case series of patients with spinal pain managed primarily by telehealth during the first 6 months of the SARS-CoV-2 pandemic in the United States.

Setting

A single center community based out-patient clinic and ambulatory surgical facility.

Subjects

101 consecutive adult patients complaining of cervicothoracic or low back pain presenting to a specialized spine clinic.

Methods

Telehealth was the preferred method of consultation for 101 consecutive patients presenting with cervicothoracic and/or low-back pain. After conservative care, patients with continued pain and disability were offered procedures. Disability Index (NDI and ODI) and pain Visual Analog Scores (VAS) were used to determine patient outcomes.

Results

101 new out-patient consultations occurred. Telehealth initial consultation occurred in 98% of cases. There was a total of 504 follow up consultations. Follow up was via telehealth in 69%. Significant neurological abnormalities were detected by telehealth in 3% of patients. The lost to follow up rate was 10%. All 63 interventional procedures performed on 42 patients were completed as planned during telehealth visits. Likewise for all 9 surgical procedures. Outcomes were monitored via telehealth. Overall, for patients with cervicothoracic pain, minimal clinically important differences (MCID) for VAS or NDI were reached in 71%. Overall, the MCID for VAS or ODI for low back pain patients was reached in 70%.

Conclusion

Telehealth in our series was easily deployable, highly feasible, allowed accurate monitoring of patient care and resulted in accurate triaging for interventions and surgery. Overall patient outcomes compare favorably with that reported for in-person spinal pain care. Telehealth was effective and easily utilizable.

Effects of Virtual Reality for Postural Control in Chronic Neck Pain: A Single-Blind, Randomized Controlled Study

OBJECTIVE

The purpose of this study was to investigate the effects of virtual reality (VR) on postural control, posture, and kinesiophobia in patients with chronic neck pain (CNP).

METHODS

Forty-one participants with CNP were randomly allocated to the VR and control groups. The VR group experienced VR with glasses for 20 minutes and then performed motor control (MC) exercises for 20 minutes. The control group received only MC exercises for 40 minutes. Both groups received 18 sessions over 6 weeks. Computerized dynamic posturography outcomes, including sensory organization test (SOT), limits of stability, and unilateral stance tests, gait speed, forward head posture (FHP), shoulder protraction (SP), cervical lordosis angle, kinesiophobia, and exercise compliance were recorded.

RESULTS

The VR group had more effects regarding composite equilibrium (Cohen's d = 1.20) of SOT and kinesiophobia (Cohen's d = -0.96), P < .05). Also, the VR group was more effective in exercise compliance (P < .05). Contrary to these results, the control group was more effective in correcting FHP and SP (Cohen's d > 0.7, P < .05).

CONCLUSION

Virtual reality seemed to have an effect on postural control, posture, and kinesiophobia in patients with chronic neck pain.

Virtual reality and motor control exercises to treat chronic neck pain: A randomized controlled trial

AIM

To compare the effects of virtual reality (VR) and motor control (MC) exercises.

METHODS

Forty-one participants with chronic neck pain (CNP) were randomized into the VR or MC group. Both groups performed 18 sessions over 6 weeks. The primary outcomes were pain intensity (visual analogue scale), pain pressure thresholds (PPTs), joint position sense error (JPSE), and muscle performance. The secondary outcomes were the Profile Fitness Mapping Questionnaire (ProFitMap-Neck), Hospital Anxiety-Depression Scale (HADS), and quality of life (SF-36). Data were analysed using T-Tests, and Fisher's Exact Test. Mean (standard deviation), median (interquartile range), effect size and %95 confidence interval (CI) were reported.

RESULTS

The results of Independent T-Tests showed that VR was advantageous in terms of PPTs of the C1/C2 and C5/C6 articular pillar bilaterally and large effect size (Cohen's d > 0.8, p < 0.05). Moreover, VR was more effective in decreasing JPSE (Cohen's d > 0.08; mean difference changes between -2.91 and -1.24, %95 CI -4.47 to 0.80) and functional limitation (ProFitMap-Neck) (Cohen's d = 0.7, mean difference 8.27, %95 CI 0.20 to 16.35). The results of T-Tests demonstrated that neither intervention was superior in terms of pain intensity, muscle performance, symptoms (ProFitMap-Neck), HADS, or SF-36 (Cohen's d < 0.5).

CONCLUSIONS

VR can be applied for improving proprioception and for decreasing cervical articular pain in CNP patients. In addition, VR may be more effective for decreasing functional limitations in patients. Clinicians can choose MC exercises with or without VR for improving pain, muscle performance, symptoms, anxiety/depression, and quality of life.

Evaluation of a physical activity promotion intervention for adults with whiplash associated disorders: a single-case experimental design study

PURPOSE

There is considerable variation in the physical and psychological presentations of people with whiplash-associated disorder (WAD). Optimal treatment continues to be a challenge. This research evaluated the efficacy of a community-located, theory-based intervention designed to promote physically active behaviour in people with persistent WAD, and thereby improve perceptions of pain interference and confidence completing activities in the presence of neck pain.

MATERIALS AND METHODS

A multiple-baseline, single-case experimental design was used to evaluate the 16-week intervention across six participants.

RESULTS

Weighted Tau-U showed significantly increased accelerometer-measured physical activity in three participants with large effect sizes (>0.5), with increased confidence in one participant (ES > 0.5), and reduced pain interference in another participant (ES > 0.7). Changes in other behaviours included clinically important improvements in quality of life for five participants and, in those participants with baseline symptom levels outside threshold levels, improvements in pain catastrophizing and pain self-efficacy.

CONCLUSIONS

Participation in a theory-based intervention resulted in significant improvements in physical and psychological health for five of six participants. Providing this type of community-located physical activity promotion strategy, to individuals with persistent WAD, may help address physical impairments and psychological distress commonly experienced in WAD. Trial registration: The trial was registered with the Australia and New Zealand Clinical Trials Registry (ACTRN: ACTRN12617001261303p) and ClinicalTrials.gov (Protocol Number: 2018000349/2017/743).Implications for rehabilitationRehabilitation professionals should consider recommending theory-based physical activity promotion strategies to reduce physical impairments and psychological distress in individuals with persistent WAD.Individually tailored physical activity promotion strategies may help individuals with persistent WAD become more physically active thereby reducing their risk of diseases associated with inactivity which may compound the effects of WADImprovements in physical and psychological health may occur independently of increasing habitual physical activity.Rehabilitation professionals may find that other community-located strategies which aim to promote physically active behaviour confer similar benefits for individuals with persistent WAD.

Exercise therapy for whiplash-associated disorders: a systematic review and meta-analysis

OBJECTIVES

Acute as well as chronic pain syndromes are common after whiplash trauma and exercise therapy is proposed as one possible intervention strategy. The aim of the present systematic review was to evaluate the effect of exercise therapy in patients with Whiplash-Associated Disorders for the improvement of neck pain and neck disability, compared with other therapeutic interventions, placebo interventions, no treatment, or waiting list.

CONTENT

The review was registered in Prospero (CRD42017060356) and conducted in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A literature search in PubMed, Scopus and Cochrane from inception until January 13, 2020 was combined with a hand search to identify eligible randomized controlled studies. Abstract screening, full text assessment and risk of bias assessment (Cochrane RoB 2.0) were conducted by two independent reviewers.

SUMMARY

The search identified 4,103 articles. After removal of duplicates, screening of 2,921 abstracts and full text assessment of 100 articles, 27 articles that reported data for 2,127 patients were included. The included articles evaluated the effect of exercise therapy on neck pain, neck disability or other outcome measures and indicated some positive effects from exercise, but many studies lacked control groups not receiving active treatment. Studies on exercise that could be included in the random-effect meta-analysis showed significant short-term effects on neck pain and medium-term effects on neck disability.

OUTLOOK

Despite a large number of articles published in the area of exercise therapy and Whiplash-Associated Disorders, the current evidence base is weak. The results from the present review with meta-analysis suggests that exercise therapy may provide additional effect for improvement of neck pain and disability in patients with Whiplash-Associated Disorders.

Systematic review and meta-analysis of the therapeutic management of patients with cervicogenic dizziness

BACKGROUND

Patients with cervicogenic dizziness (CGD) present with dizziness, cervical spine dysfunctions, and postural imbalance, symptoms that can significantly impact their daily functioning.

OBJECTIVES

To provide evidence-based recommendations for the management of patients with CGD.

METHODS

Three databases were searched for randomized controlled trials (RCTs) (last search 15 May 2021). Outcome measures included dizziness, cervical spine, and balance parameters. Cochrane standard methodological procedures were used and included the RoB 2.0 and GRADE. Where possible, RCTs were pooled for meta-analysis.

RESULTS

Thirteen RCTs (n = 898 patients) of high (two RCTs), moderate (five RCTs), and low (six RCTs) methodological quality were analyzed. Six RCTs were included in the meta-analysis. Only three RCTs specified the cause of CGD. They showed inconsistent findings for the effectiveness of exercise therapy in patients with traumatic CGD. Manual therapy and manual therapy combined with exercise therapy may reduce CGD, cervical spine, and balance dysfunctions.

CONCLUSION

There is moderate quality of evidence that manual therapy reduces CGD, cervical spine, and balance symptoms. When manual therapy is combined with exercise therapy, the positive effect on CGD, cervical spine, and balance symptoms is even stronger. However, the quality of the evidence here is very low.

Pregabalin vs placebo to prevent chronic pain after whiplash injury in at-risk individuals: results of a feasibility study for a large randomised controlled trial

ABSTRACT

There are few effective treatments for acute whiplash-associated disorders (WADs). Early features of central sensitisation predict poor recovery. The effect of pregabalin on central sensitisation might prevent chronic pain after acute whiplash injury. This double blind, placebo-controlled randomised controlled trial examined feasibility and potential effectiveness of pregabalin compared with placebo for people with acute WAD. Twenty-four participants with acute WAD (<48 hours) and at risk of poor recovery (pain ≥5/10) were recruited from hospital emergency departments in Queensland, Australia, and randomly assigned by concealed allocation to either pregabalin (n = 10) or placebo (n = 14). Pregabalin was commenced at 75 mg bd, titrated to 300 mg bd for 4 weeks, and then weaned over 1 week. Participants were assessed at 5 weeks and 3, 6, and 12 months. Feasibility issues included recruitment difficulties and greater attrition in the placebo group. For the primary clinical outcome of neck pain intensity, attrition at 5 weeks was pregabalin: 10% and placebo: 36% and at 12 months was pregabalin: 10% and placebo: 43%. Pregabalin may be more effective than placebo for the primary clinical outcome of neck pain intensity at 3 months (mean difference: -4.0 [95% confidence interval -6.2 to -1.7]) on an 11-point Numerical Rating Scale. Effects were maintained at 6 months but not 12 months. There were no serious adverse events. Minor adverse events were more common in the pregabalin group. A definitive large randomised controlled trial of pregabalin for acute whiplash injury is warranted. Feasibility issues would need to be addressed with modifications to the protocol.

Application areas and effects of aquatic therapy WATSU - A survey among practitioners

INTRODUCTION

WATSU (WaterShiatsu) is a treatment administered in warm water. The present study investigated if and how frequently scientifically studied application areas and effects of WATSU occur in practice, whether similar effectiveness of WATSU is observed in trials and practice, and whether practitioners can contribute additional application areas and effects of WATSU.

METHODS

Application areas and effects of WATSU reported in a recent systematic review were extracted verbatim to be assessed in a worldwide multilingual cross section online survey, generating quantitative and qualitative data. A pre-test and retest were conducted to ensure quality and evaluate the questionnaire's psychometric properties.

RESULTS

Answers of 191 respondents were processed. All proposed 26 application areas and 20 effects were confirmed, each with relatively high ratings of observed effectiveness of WATSU. WATSU was frequently applied in healthy individuals (including during pregnancy), and individuals in various pain- (e.g., low back pain, neck pain, myofascial pain, fibromyalgia) and stress-related (e.g., stress, depression, sleep disorders, fatigue, anxiety disorders) conditions. Frequently confirmed effects were physical relaxation, relief of physical tension, pain relief, increased mobility and flexibility, improved quality of life, spiritual experiences, and increased psychological health. Respondents contributed 73 additional application areas and effects (both, mental and physical) of WATSU.

CONCLUSIONS

Application areas and effects of WATSU are consistently employed practically and scientifically. Respondents' ratings of effectiveness of WATSU match tentative research efforts. WATSU is cautiously recommended for the use in pain- and stress-related conditions. Short- and long-term effectiveness of WATSU need to be evaluated in high level intervention studies.

Clinical Effectiveness and Efficacy of Chiropractic Spinal Manipulation for Spine Pain

Spine pain is a highly prevalent condition affecting over 11% of the world's population. It is the single leading cause of activity limitation and ranks fourth in years lost to disability globally, representing a significant personal, social, and economic burden. For the vast majority of patients with back and neck pain, a specific pathology cannot be identified as the cause for their pain, which is then labeled as non-specific. In a growing proportion of these cases, pain persists beyond 3 months and is referred to as chronic primary back or neck pain. To decrease the global burden of spine pain, current data suggest that a conservative approach may be preferable. One of the conservative management options available is spinal manipulative therapy (SMT), the main intervention used by chiropractors and other manual therapists. The aim of this narrative review is to highlight the most relevant and up-to-date evidence on the effectiveness (as it compares to other interventions in more pragmatic settings) and efficacy (as it compares to inactive controls under highly controlled conditions) of SMT for the management of neck pain and low back pain. Additionally, a perspective on the current recommendations on SMT for spine pain and the needs for future research will be provided. In summary, SMT may be as effective as other recommended therapies for the management of non-specific and chronic primary spine pain, including standard medical care or physical therapy. Currently, SMT is recommended in combination with exercise for neck pain as part of a multimodal approach. It may also be recommended as a frontline intervention for low back pain. Despite some remaining discrepancies, current clinical practice guidelines almost universally recommend the use of SMT for spine pain. Due to the low quality of evidence, the efficacy of SMT compared with a placebo or no treatment remains uncertain. Therefore, future research is needed to clarify the specific effects of SMT to further validate this intervention. In addition, factors that predict these effects remain to be determined to target patients who are more likely to obtain positive outcomes from SMT.

Use of Soft Cervical Collar among Whiplash Patients in Two Italian Emergency Departments Is Associated with Persistence of Symptoms: A Propensity Score Matching Analysis

Purpose: Although the use of soft cervical collars in the emergency department (ED), for whiplash-associated disorders (WAD), is controversial, it is still widely adopted. The purpose of our study was to investigate the impact of the early use of soft cervical collars on the return to the ED, within three months of a road traffic collision. Methods: We conducted a retrospective observational study on WAD patients from two EDs in Verona (Italy). Patients in the earlier acute phase of WAD (within 48 h from the trauma) were included; those with serious conditions (WAD IV) were excluded. As an end point, we considered patients who returned to the ED complaining of WAD symptoms within three months as positive outcome for WAD persistence. Results: 2162 patients were included; of those, 85.4% (n = 1847/2162) received a soft cervical collar prescription. Further, 8.4% (n = 156/1847) of those with a soft cervical collar prescription, and 2.5% (n = 8/315) of those without a soft cervical collar (p < 0.001) returned to the ED within three months. The use of the soft cervical collar was an independent risk factor for ED return within three months, with an OR, adjusted for possible clinical confounders, equal to 3.418 (95% CI 1.653–7.069; p < 0.001). After the propensity score matching, 25.5% of the patients (n = 25/98) using the soft cervical collar returned to the ED at three months, compared to the 6.1% (n = 6/98) that did not adopt the soft cervical collar. The use of a soft cervical collar was associated with ED return with an OR = 4.314 (95% CI 2.066–11.668; p = 0.001). Conclusions: Our study shows that the positioning of the soft collar in a cohort of patients with acute WAD, following a rear-end car collision, is an independent potential risk factor to the return to the ED. Clinically, the use of the collar is a non-recommended practice and seems to be related to an increased risk of delayed recovery. There is a need to inform healthcare providers involved in the ED of the aim to limit the use of the soft cervical collar. A closer collaboration between clinicians (e.g., physicians, physical therapists, nurses) is suggested in the ED. Future primary studies should determine differences between having used or not having used the collar, and compare early physical therapy in the ED compared with the utilization of the collar.

Effectiveness of self-applied acupressure for cervical pain of benign origin (EDIDO-CUH): a randomized controlled clinical trial

BACKGROUND

Cervical pain is a problem with a high prevalence of ~13% of the population, and is more common in women (16.5%). The most affected age group is 65-74 years. Our aim was to assess the effectiveness of self-applied acupressure for decreasing benign-origin cervical pain, under the supervision of a health professional and in combination with usual treatment, as well as to examine its impact on the patient's self-perceived health condition and their opinion of the technique.

METHODS

Pragmatic, multicenter, controlled clinical trial randomized by healthcare center. A total of 160 patients with benign-origin cervical pain between 18 and 65 years of age who attended primary care were included from 12 healthcare centers in the autonomous community of Madrid by consecutive sampling, and randomly assigned to a control or intervention group. The main outcome variable was pain intensity measured on a visual analogue scale (VAS) and secondary variables were self-perceived quality of life (EuroQol-5D utility index) and functional ability (neck disability index). An explanative model of generalized estimating equations was built taking into account the lack of independence among observations. The analysis was performed over 6 months.

RESULTS

In total, 150 patients completed the study. Mean age was 45 years (SD: 10.7), 86.7% were women, 86.2% were currently employed, and 57.9% did not perform any physical exercise. Average days experiencing pain was 32.9 (SD: 2.8) and 80% were undergoing previous pharmacological treatment. The quality of life utility index after 3 months was 1.6 points (95% CI: 0.54-2.71) higher in the intervention group. The pain score on the VAS was 0.16 points (95% CI: 0.80-0.48) lower in the intervention group. The health professional explained 10.4% of the reduction in pain observed on the VAS throughout the medical visits.

CONCLUSION

Acupressure applied in addition to usual practice appeared to improve cervical pain in the long term. The effectiveness of this technique was partially explained by the health professional that trained the participants on technique application.

Virtual Reality Exercises in an Interdisciplinary Rehabilitation Programme for Persons with Chronic Neck Pain: a Feasibility Study

Objective

To investigate the feasibility of a virtual reality exercise intervention within an interdisciplinary rehabilitation programme for persons with chronic neck pain. The effects of the intervention on symptom severity, variables related to chronic neck pain, and patients' experience of exercises were assessed.

Methods

Nine women and 3 men participated in a 6-week virtual reality exercise intervention during an interdisciplinary rehabilitation programme. Symptom severity was rated before and after each session of virtual reality exercise, using questionnaires before and after the interdisciplinary rehabilitation programme, and questions about participants' experiences.

Results

Neck pain symptoms increased temporarily during the exercises, but no lasting deterioration was found after the interdisciplinary rehabilitation programme. Depression, pain interference, pain control, sleep and kinesiophobia improved significantly after the programme. Participants experienced that the virtual reality exercises increased motivation to exercise and provided a focus other than pain. However, the equipment was heavy; and exercising was tiring and reminded them of their challenges.

Conclusion

This study indicates that virtual reality exercises as part of an interdisciplinary rehabilitation programme are feasible and safe for patients with chronic neck pain. Pain symptoms may increase temporarily during the exercises. Virtual reality exercises may support participants by increasing motivation to exercise and providing helpful feedback. Further research into the added value of virtual reality exercises in an interdisciplinary rehabilitation programme for patients with chronic neck pain is warranted.

Responses after spinal interventions in a clinical pain practice - a pragmatic observational study

Introduction There is limited evidence for effect of interventional treatment, and pragmatic studies are needed to assess these interventions within a clinical setting. The aim of this study was to describe patients referred to an interventional pain clinic and investigate responses after spinal intervention in general and for radiofrequency ablation (RFA) and transforaminal epidural corticosteroid administration (TECA), specifically. Methods This is a prospective, non-controlled study of patients with chronic spinal pain. The procedures were performed in accordance with the Spine Intervention Society recommendations. Outcome data after a median of 4.5 months are presented, and for those treated with RFA also after 6 and 12 months. Results Among 815 patients, 190 patients underwent diagnostic blocks only and 625 interventional treatment, of these 94 RFA and 246 TECA. Of the whole sample 70% reported pain reduction, for 49% ≥ 50%, while 9% were pain free (p < 0.001). Highest pain intensity decreased from 7.1 to 5.4 [95% Confidence Interval of the Difference (95%-CI): 1.4-1.9] (p < 0.001), while Euroqual - visual analogue scale for general health (EQ-VAS) improved from 48 to 58 (95%-CI: 7.6-11.9) (p < 0.001), and Euroqual-5 Dimensions-5 Levels Index for health related quality of life (EQ-5D-5L Index) from 0.489 to 0.628 (95%-CI: 0.123-0.157) (p < 0.001). The proportions, not taking analgesics, increased from 16% to 30%, and proportion taking strong opioids decreased from 14% to 9% (p < 0.001). We found no significant change in proportion receiving physiotherapy/other treatment nor occupational status. No complications were reported. Among patients treated with RFA, 77% reported pain reduction, for 56% ≥ 50%, while 9% were pain free (p < 0.001). Highest pain intensity decreased from 6.9 to 4.6 (95%-CI: 1.6-3.0) (p < 0.001), while EQ-VAS improved from 47 to 57 (95%-CI: 4.8-13.6 (p < 0.001), and EQ-5D-5L Index from 0.489 to 0.643 (95%-CI: 0.117-0.191) (p < 0.001). The proportion not taking analgesics, increased from 7% to 23% and proportion taking strong opioids decreased from 16% to 10%. Among patients who responded at 6- and 12-month follow up, the proportions reporting pain reduction, EQ-VAS, and EQ-5D-5L Index remained significantly improved from baseline, and the change in proportions taking analgesic and opioids achieved statistical significance. We found no significant change in proportion receiving physiotherapy/other treatment nor occupational status. Among patients treated with TECA, 58% reported pain reduction, for 36% ≥ 50%, while 5% were pain free (p < 0.001). Highest pain intensity decreased from 7.2 to 6.2 (95%-CI 0.5-1.4) (p < 0.001), while EQ-VAS improved from 46 to 52 (95%-CI: 2.0-3.6) (p < 0.001), and EQ-5D-5L Index from 0.456 to 0.571 (95%-CI: 0.077-0.138) (p < 0.001). The proportions, not taking analgesics, increased from 17% to 27% and proportion taking strong opioids decreased from 15% to 10%, but the changes did not reach statistical significance. We found no significant changes in the proportion who recieved physiotherapy/other treatment nor occupational status. Conclusion The study demonstrates substantial short-term responses after spinal intervention and long-lasting improvement for a subsample of the RFA treated patients. We observed larger proportions reporting pain reduction among those treated with cervical RFA. Implementation Quality assessment should be implemented in interventional pain clinics to improve treatment quality.

Experiences of responsiveness to exercise in people with chronic whiplash: A qualitative study

Exercise is recommended in clinical guidelines for the treatment of chronic whiplash associated disorders (WAD). However, randomised controlled trials have shown similar effects for comprehensive exercise programs and advice. To date, there is no clear understanding of why some individuals with WAD appear to respond to exercise whilst others do not. The aim of this study was to explore the experiences and self-reported characteristics of people with chronic whiplash identifying as 'responders' and 'non-responders' to exercise. Semi-structured interviews were conducted with 13 people with chronic whiplash (patients) and seven treating physiotherapists. Patients were asked whether they responded to the exercise program, and what contributed to this. Physiotherapists were asked to share their experiences about the characteristics of people that appear to respond to exercise, and those that do not. An interpretive descriptive approach was selected to facilitate the generation of discipline-specific knowledge. Four themes were generated from patient and physiotherapist interviews, including: (1) the therapeutic relationship, (2) exercise experiences and beliefs, (3) self-efficacy and acceptance, (4) physical and psychological determinants of responsiveness. Responsiveness to exercise is complex and multifaceted. Clinicians may seek to identify the presence of discrete physical impairment(s) (e.g., range of motion restriction), and where present, determine whether targeted exercise results in an immediate and positive response. Clinicians may also focus their efforts on developing aspects of the therapeutic relationship identified as important to patients, such as hope, partnership and rapport.

Combining Stress Management With Pain Neuroscience Education and Exercise Therapy in People With Whiplash-Associated Disorders: A Clinical Perspective

Individuals classified as having whiplash-associated disorder (WAD) grade II, which reflects approximately 93% of people with WAD who are commonly managed by health care professionals, exhibit both physical (eg, pain and disability) and psychological (eg, fear of movement, anxiety, posttraumatic stress) problems that, in approximately 50% of cases, persist beyond 3 months. There is still much ongoing debate regarding factors predictive of poor recovery. The strongest associations have been found for high initial pain and disability following whiplash injury. In addition, a growing body of evidence supports the clinical importance of characteristic features, such as disturbed nociceptive processing (eg, local or general hyperalgesia to cold and mechanical stimuli), inefficient cognitions and beliefs about pain/movement/recovery, and posttraumatic stress symptoms, in the development and maintenance of physical and psychological manifestations in individuals with WAD. For this reason, the field shifted away from single interventions that mainly follow a biomedical approach, such as exercise therapy and activity programs, to gold standard multimodal care (at least 2 distinct therapeutic modalities given by 1 or more health care professionals) that acknowledges the biopsychological nature of WAD. To date, there exist several multimodal care approaches to managing WAD; however, for most, the efficacy has been found to be rather limited. One may argue that the limited success of some approaches can be attributed to the fact that they focused mainly on rehabilitating the physical symptoms (eg, pain, disability) rather than also the associated cognitive (eg, catastrophizing) and psychological (eg, posttraumatic stress symptoms) symptoms of the condition, leaving much room for improvement. In this article, current and previous evidence is used to explain why and how a comprehensive and multimodal treatment for people with WAD-consisting of a combination of pain neuroscience education, cognition-targeted exercise therapy, and stress management-can be applied in clinical practice.

"I've learned to look at things in a different way": exploring patients' perspectives on participation in physiotherapist delivered integrated stress inoculation training and exercise for acute whiplash

PURPOSE

To explore patient perspectives of the integrated intervention (intervention arm) of a recent randomised clinical trial that found clinically relevant and sustained benefits of a physiotherapist delivered integrated stress inoculation training (SIT) and exercise for people with acute whiplash-associated disorders (WAD) and at risk of poor recovery.

MATERIAL AND METHODS

Twelve patients from the 53 who participated in the SIT and exercise arm of a randomised controlled trial (StressModex RCT) participated in semi-structured interviews. Data were analysed using inductive thematic analysis.

RESULTS

Five main themes were identified: "balance between the physical and psychological components," "dealing with stress," "coping with the injury," "pain relief and return to function," and "elements enhancing therapeutic alliance."

CONCLUSIONS

The majority of patients found the SIT techniques to be helpful in managing stress and pain, coping with their injury, and returning to function. The patients also found the exercises useful and acknowledged the importance of both the physical and the psychological aspects of whiplash injury.IMPLICATIONS FOR REHABILITATIONPatients with acute WAD at risk of poor recovery welcomed the inclusion of psychological strategies as part of physiotherapy treatment.The patients nominated both the psychological (SIT) component and exercise as assisting them with their stress, pain, and recovery.Physiotherapists could consider including strategies targeting early stress responses in their management of patients with acute WAD.

Trauma-focused cognitive behavioural therapy and exercise for chronic whiplash with comorbid posttraumatic stress disorder: a randomised controlled trial

ABSTRACT

Many people with chronic whiplash-associated disorders (WAD) have also symptoms of posttraumatic stress disorder (PTSD), but this is rarely considered in usual predominantly exercise-based interventions. We aimed to investigate the effectiveness of combined trauma-focused cognitive behavioural therapy (TF-CBT) and exercise compared with supportive therapy (ST) and exercise for people with chronic WAD and PTSD. A randomised controlled multicentre trial with concealed allocation, assessor blinding, and blinded analysis was conducted. One hundred three participants with chronic WAD (>3 months and <5 years, grade II) and PTSD were randomised to TF-CBT and exercise (n = 53) or ST and exercise (n = 50). Both interventions comprised 10 weeks of TF-CBT or ST, followed by 6 weeks of exercise. Outcomes were measured at baseline, 10, 16 weeks, 6, and 12 months after randomisation. Analysis was intention to treat using linear mixed models. There was no difference between the interventions on the primary outcome of neck pain-related disability at any time point. At 16 weeks, the treatment effect on the 0 to 100 Neck Disability Index was 0.59 (95% confidence interval [CI] 5.51 to -4.33), at 6 months 1.18 (95% CI 6.15 to -3.78), and at 12 months 1.85 (95% CI 6.81 to -3.11). In addition, there was no difference between the interventions for most secondary outcomes at any time. Exceptions were in favour of TF-CBT and exercise, where improvements in PTSD symptoms were found at 16 weeks. From 16 weeks onwards, both groups achieved a clinically important improvement in neck pain-related disability. However, both groups remained moderately disabled.

Craniocervical flexion performance in computer users: An observational study

Study aim: To compare the performance of deep cervical flexors (DCF) among computer users (CU) and non-users using the craniocervical flexion test (CCFT).

Material and methods: Eighty nine computer users and 100 non-users were recruited for evaluation of their craniocervical muscle performance. The activation score and performance index were assessed using the CCFT. Comparison of craniocervical flexor performance between the two groups was evaluated using the Mann Whitney test. A Chi-Square test was used to test the association between age, years of work and craniocervical flexion. Significance was set at p ≤ 0.05.

Results: The median activation score was lower among computer users (median pressure-24 mmHg as compared to non-users (median pressure-28 mmHg) (p < 0.01). The performance index among computer users was lower when compared to non-users. Also, age (p < 0.001) and the years of work experience (p = 0.006) were associated with the DCF performance.

Conclusion: CU have lower activation and endurance of the DCF compared to non-users. The endurance of the DCF was associated with the age and years of computer usage.

The incidence of impingement syndrome in cases of cervical radiculopathy: An analysis of 220 cases

BACKGROUND

We hypothesized that cervical radiculopathy (CR) has a role in subacromial impingement syndrome (SAIS) etiology, which cannot be directly connected to anatomical causes.

OBJECTIVE

We aimed to investigate the presence of cervical radiculopathy in patients with SAIS diagnosed clinically and radiologically.

METHODS

Patients who had a clinical and radiological SAIS diagnosis between 2014 and 2016 were included in the study. Patients with secondary causes that led to SAIS were excluded. Cervical MRI of all patients with SAIS was examined for cervical radiculopathy.

RESULTS

A significant (p< 0.05) relationship was found between SIAS and the presence of root compression on the same side. 35% of the patients with SIAS had root compression on the same side.

CONCLUSIONS

Cervical radiculopathy and shoulder impingement syndrome can be easily confused due to the similarity of the symptoms and the anatomical proximity of the lesions. Although both diseases can occur with different mechanisms, we believe that there is a cause and effect relationship between them.

The mechanisms of effect of a physiotherapist-delivered integrated psychological and exercise intervention for acute whiplash-associated disorders: secondary mediation analysis of a randomized controlled trial

Supplemental Digital Content is Available in the Text. Stress mediated the effect of a physiotherapist-delivered integrated intervention on multiple health outcomes and pain-related coping mediated the effect on pain self-efficacy only. Changes in depressive and posttraumatic stress symptoms were also mechanisms of effect.

Introduction:

Integrated psychological and physical treatments can improve recovery for whiplash-associated disorders (WADs). Little is known about how these interventions work.

Objective:

To examine the mechanisms by which a physiotherapist-delivered integrated intervention for acute WAD improves health outcomes.

Methods:

Secondary analysis using structural equation modelling of a randomized controlled trial comparing integrated stress inoculation training and exercise to exercise alone for acute WAD. Outcomes were disability, pain self-efficacy, pain intensity, and health-related quality of life at 12 months. The intended intervention target and primary mediator, stress was tested in parallel with pain-related coping, an additional cognitive behavioral mediator that significantly improved at posttreatment (Model 1). Stress-related constructs that commonly co-occur with stress and pain were also tested as parallel mediators: depression and pain-related coping (Model 2); and posttraumatic stress and pain-related coping (Model 3).

Results:

Reductions in stress mediated the effect of the integrated intervention on disability (β = −0.12, confidence interval [CI] = −0.21 to −0.06), pain self-efficacy (β = 0.09, CI = 0.02–0.18), pain (β = −0.12, CI = −0.21 to −0.06), and health-related quality of life (β = 0.11, CI = 0.04–0.21). There was an additional path to pain self-efficacy through pain-related coping (β = 0.06, CI = 0.01–0.12). Similar patterns were found in Models 2 and 3.

Conclusions:

Improvements in stress and related constructs of depression and posttraumatic stress, and pain-related coping were causal mechanisms of effect in a physiotherapist-delivered integrated intervention. As integrated interventions are growing in popularity, it is important to further personalize interventions for improved benefit.

Does Pain Neuroscience Education and Cognition-Targeted Motor Control Training Improve Cervical Motor Output? Secondary Analysis of a Randomized Clinical Trial

BACKGROUND

In the context of interventions aimed at reducing pain, disability, and maladaptive pain cognitions in chronic neck pain, it is hypothesized that patients who have greater symptom reduction possibly also demonstrate greater improvement in cervical motor output. Therefore, the aim of this study was to examine the effect of pain neuroscience education plus cognition-targeted motor control training on cervical motor output.

METHODS

Impairments in cervical motor output were measured in 64 subjects with chronic neck pain using standardized tests. Cervical muscle strength, cervical mobility, balance, and cervical neuromuscular control were derived. To assess the differences between groups in response to treatment, a random-intercept linear mixed-models analysis, applying a diagonal covariance matrix, was used.

RESULTS

A significant treatment × time interaction effect was found for neuromuscular control of the deep cervical flexors, favoring the experimental treatment at 3 months' follow-up (mean group difference: 1.982; 95% confidence interval 0.779, 3.185; large effect size d = 0.82). Significant main effects of time were found for the neuromuscular capacity of scapulothoracic muscles and for cervical mobility. No significant effects were found for balance, cervical muscle strength, or endurance of cervical flexors.

CONCLUSION

Pain neuroscience education combined with cognition-targeted motor control training is not more effective than biomedically focused education and exercise therapy for improving cervical motor output in people with chronic neck pain. Our findings question the relative importance of factors such as pain, disability, and maladaptive pain cognitions on cervical motor output and the need to address it in treatment.

Recovery despite everyday pain: Women's experiences of living with whiplash-associated disorder

INTRODUCTION

Living with whiplash-associated disorders (WAD) means living every day under the influence of pain and limitations. As the incidence of WAD and the related intensity of pain are somewhat higher among women than men, the aim of the present study was to describe women's experiences of living with WAD.

METHODS

A purposive sample of seven women participated in individual in-depth qualitative interviews, the transcripts of which were subjected to qualitative content analysis.

RESULTS

The results of the analysis suggested six themes of women's experiences with WAD: living with unpredictable pain; trying to manage the pain; living with limitations; being unable to work as before; needing support and understanding; and learning to live with limitations. The findings showed that unpredictable pain limited women's strength to engage in activities of daily life and be as active as before. Support and understanding were important for their ability to manage changes in their daily lives.

CONCLUSIONS

Pain considerably affects the daily lives of women with WAD, particularly by limiting their ability to perform activities and to enjoy their professional and social lives. As women with WAD need support with managing their daily lives, nurses and other healthcare personnel should adopt a person-centred approach, in order to support such women according to their individual needs and circumstances.

Personalised treatments for acute whiplash injuries: A pilot study of nested N-of-1 trials in a multiple baseline single-case experimental design

BACKGROUND

Whiplash associated disorder (WAD), a common and disabling condition, incurs huge burden and costs to Australia. Yet, current treatments for whiplash are not very effective; improved outcomes are urgently needed. Clinical guidelines recommend simple analgesia (paracetamol and non-steroidal anti-inflammatory drugs) but there have been no trials of guideline-recommended drugs. This study will investigate the effectiveness of evidence-based advice (EBA), paracetamol, naproxen, and both paracetamol and naproxen, in reducing daily neck pain and preventing chronic neck pain after whiplash injury.

METHODS

This study is a pilot series of multi-cycle, double-blinded, randomised N-of-1 trials, nested in a multiple baseline design. The design will comprise three baselines of 5, 8 or 11 days duration. Post enrolment, participants will be randomly assigned to one of the baselines. Fifteen participants with acute (<2 weeks) Grade II WAD, experiencing at least moderate pain (NRS: ≥ 5/10), and at risk of poor recovery will be recruited from hospitals in Queensland, Australia, and through local physiotherapists. Patients will receive EBA plus a randomised sequence of three cycles of ten day treatment triplets (paracetamol designated as a C phase, naproxen, designated as a D phase, and both paracetamol and naproxen, designated as an E phase).

DISCUSSION

We will test the effects of different treatments on the primary outcome of average neck pain intensity collected daily and at 4 and 7 months post-injury. Secondary outcomes, including disability, depression, post-traumatic stress symptoms, pain catastrophizing, and feasibility of study procedures, will also be evaluated. The results of this study will inform a larger trial aiming to strengthen the evidence on EBA and simple analgesics for WAD.

Qigong and Musculoskeletal Pain

PURPOSE OF REVIEW

Musculoskeletal pain is a widespread symptom that commonly produces considerable disability, particularly in later life. This brief review strove to summarize and critically review the recent research base concerning the use of Qigong as a possible strategy for alleviating longstanding or chronic musculoskeletal pain states.

METHODS

Research reports and literature reviews specifically focusing on Qigong and its impact on various forms of musculoskeletal pain between 2015 and 2019 were sought and analyzed, along with related data.

RESULTS

Collectively, these data reveal that while more research is indicated, Qigong practice may help to attenuate pain in varying degrees among adults with different forms of chronic pain with few side-effects.

CONCLUSION

More research is needed to ensure health professionals working with adults who have chronic unrelenting musculoskeletal pain may safely recommend these exercises as one possible remedy for reducing intractable musculoskeletal pain.

Best Evidence Rehabilitation for Chronic Pain Part 4: Neck Pain

Neck pain, whether from a traumatic event such as a motor vehicle crash or of a non-traumatic nature, is a leading cause of worldwide disability. This narrative review evaluated the evidence from systematic reviews, recent randomised controlled trials, clinical practice guidelines, and other relevant studies for the effects of rehabilitation approaches for chronic neck pain. Rehabilitation was defined as the aim to restore a person to health or normal life through training and therapy and as such, passive interventions applied in isolation were not considered. The results of this review found that the strongest treatment effects to date are those associated with exercise. Strengthening exercises of the neck and upper quadrant have a moderate effect on neck pain in the short-term. The evidence was of moderate quality at best, indicating that future research will likely change these conclusions. Lower quality evidence and smaller effects were found for other exercise approaches. Other treatments, including education/advice and psychological treatment, showed only very small to small effects, based on low to moderate quality evidence. The review also provided suggestions for promising future directions for clinical practice and research.

Is kinesiophobia and pain catastrophising at baseline associated with chronic pain and disability in whiplash-associated disorders? A systematic review

BACKGROUND

Kinesiophobia and pain catastrophising may be associated with patients' transition from having acute to chronic pain following a whiplash injury.

OBJECTIVE

To systematically review and critically appraise the literature to determine whether kinesiophobia and pain catastrophising are associated with greater likelihood of patients developing chronic pain and disability following a whiplash injury.

DESIGN

A systematic review of the literature DATA SOURCES: Electronic searches of PubMed, AMED, CINAHL, PsycINFO, and PubPsych, and grey literature were undertaken from inception to September 2017.

ELIGIBILITY CRITERIA FOR SELECTING STUDIES

Study selection was based on longitudinal studies evaluating how kinesiophobia and/or pain catastrophising at baseline are associated with pain intensity, disability or both after a whiplash injury.

RESULTS

We included 14 longitudinal studies that described 12 independent cohorts with a total sample of 2733 participants with whiplash-associated disorder. Kinesiophobia at baseline was not associated with pain intensity over time (three studies). Whether kinesiophobia at baseline was associated with disability was unclear as results were conflicting (six studies). There were also conflicting results when we examined the association between pain catastrophising and both pain intensity (five studies) and disability (eight studies).

SUMMARY/CONCLUSIONS

Kinesiophobia at baseline was not associated with pain intensity over time. There were conflicting results for the remaining analyses. The size of the associations was small. The overall quality of the evidence was very low.

An analysis of whiplash injury outcomes in an Irish population: a retrospective fifteen-year study of a spine surgeon's experience

BACKGROUND

Whiplash injuries result from an acceleration-deceleration injury of the cervical spine. The associated symptoms may include neck pain/stiffness; cervicogenic headaches; interscapular pain; upper limb pain, paraesthesia and weakness. Current treatment protocols recommend conservative management of low-grade whiplash.

AIMS

To assess changing practices over time in the management of whiplash-associated disorders in the practice of a specialist spine surgeon and to explore the impact of associated litigation on this patient cohort.

METHODS AND RESULTS

The private medical records of a specialist spine surgeon over a 15-year period (1996-2011) were reviewed. Three hundred one consecutive patients were identified: 169 females and 132 males with a mean age of 37 years ± 13. All were referred by primary care with potential soft tissue injury of the cervical spine following a road traffic accident. Fifty-eight percent had associated back pain. An initial conservative approach was adopted in all cases. Subsequently, 4 patients underwent surgical intervention. Ninety-three percent reported chronic neck pain > 6 months after their injury. Age was the only significant predictor of chronic neck pain (adjusted OR 1.29 for every 5-year increase, p = 0.03). All were ultimately involved in litigation. The establishment of the Personal Injuries Board did not influence the litigation duration during the study period.

CONCLUSION

Whiplash poses a significant societal economic burden in Ireland and was associated with prolonged symptoms including neck pain and upper limb neuropathic symptoms in this cohort. Associated low-back pain was common. Litigation was linked with presentation in all cases.

Traditional physical therapy exercises combined with sensorimotor training: The effects on clinical outcomes for chronic neck pain in a double-blind, randomized controlled trial

OBJECTIVE

This study examined the effects of combining traditional physical therapy exercises with sensorimotor training on joint position sense, pain, muscle endurance, balance and disability in patients with chronic, non-specific neck pain.

DESIGN

Double-blind, randomized controlled trial.

SUBJECTS

A total of 53 patients with chronic non-specific neck pain were randomized to either traditional or combined exercise groups.

INTERVENTIONS

All patients received 12 sessions of supervised intervention 3 times per week. The traditional group performed traditional exercises, and the combined exercise group performed sensorimotor training in addition to traditional exercises.

OUTCOME MEASURES

Joint position sense, pain, neck flexor muscle endurance test, 10 Meter Walk Test, step test, and the Neck Disability Index.

RESULTS

The combined exercise group showed significantly greater improvement compared to the traditional group in joint position sense during extension, flexion, right rotation, the 10 m walk test with head turn, and the step test. Pain intensity, muscle endurance, and disability improved in both groups. Additionally, there was a higher degree of effect on muscle endurance in the combined exercise group compared to a moderate effect in the traditional group.

CONCLUSIONS

A combination of sensorimotor training with traditional physical therapy exercises could be more effective than traditional exercises alone in improving joint position sense, endurance, dynamic balance and walking speed.

Is a government-regulated rehabilitation guideline more effective than general practitioner education or preferred-provider rehabilitation in promoting recovery from acute whiplash-associated disorders? A pragmatic randomised controlled trial

OBJECTIVE

To evaluate the effectiveness of a government-regulated rehabilitation guideline compared with education and activation by general practitioners, and to a preferred-provider insurance-based rehabilitation programme on self-reported global recovery from acute whiplash-associated disorders (WAD) grade I-II.

DESIGN

Pragmatic randomised clinical trial with blinded outcome assessment.

SETTING

Multidisciplinary rehabilitation clinics and general practitioners in Ontario, Canada.

PARTICIPANTS

340 participants with acute WAD grade I and II. Potential participants were sampled from a large automobile insurer when reporting a traffic injury.

INTERVENTIONS

Participants were randomised to receive one of three protocols: government-regulated rehabilitation guideline, education and activation by general practitioners or a preferred-provider insurance-based rehabilitation.

PRIMARY AND SECONDARY OUTCOME MEASURES

Our primary outcome was time to self-reported global recovery. Secondary outcomes included time on insurance benefits, neck pain intensity, whiplash-related disability, health-related quality of life and depressive symptomatology at 6 weeks and 3, 6, 9 and 12 months postinjury.

RESULTS

The median time to self-reported global recovery was 59 days (95% CI 55 to 68) for the government-regulated guideline group, 105 days (95% CI 61 to 126) for the preferred-provider group and 108 days (95% CI 93 to 206) for the general practitioner group; the difference was not statistically significant (Χ²=3.96; 2 df: p=0.138). We found no clinically important differences between groups in secondary outcomes. Post hoc analysis suggests that the general practitioner (hazard rate ratio (HRR)=0.51, 95% CI 0.34 to 0.77) and preferred-provider groups (HRR=0.67, 95% CI 0.46 to 0.96) had slower recovery than the government-regulated guideline group during the first 80 days postinjury. No major adverse events were reported.

CONCLUSIONS

Time-to-recovery did not significantly differ across intervention groups. We found no differences between groups with regard to neck-specific outcomes, depression and health-related quality of life.

Physiotherapist-delivered stress inoculation training integrated with exercise versus physiotherapy exercise alone for acute whiplash-associated disorder (StressModex): a randomised controlled trial of a combined psychological/physical intervention

Objective

There are few effective treatments for acute whiplash-associated disorders (WAD). Early symptoms of postinjury stress predict poor recovery. This randomised controlled trial (StressModex) investigated whether physiotherapist-led stress inoculation training integrated with exercise is more effective than exercise alone for people with acute WAD.

Methods

108 participants (<4 weeks) at risk of poor recovery (moderate pain-related disability and hyperarousal symptoms) were randomly assigned by concealed allocation to either physiotherapist-led stress inoculation training and guideline-based exercise (n=53) or guideline-based exercise alone (n=55). Both interventions comprised 10 sessions over 6 weeks. Participants were assessed at 6 weeks and at 6 and 12 months postrandomisation. Analysis was by intention to treat using linear mixed models.

Results

The combined stress inoculation training and exercise intervention was more effective than exercise alone for the primary outcome of pain-related disability at all follow-up points. At 6 weeks, the treatment effect on the 0–100 Neck Disability Index was (mean difference) −10 (95% CI −15.5 to −4.48), at 6 months was −7.8 (95% CI −13.8 to −1.8) and at 12 months was −10.1 (95% CI −16.3 to −4.0). A significant benefit of the stress inoculation and exercise intervention over exercise alone was also found for some secondary outcomes.

Conclusion

A physiotherapist-led intervention of stress inoculation training and exercise resulted in clinically relevant improvements in disability compared with exercise alone—the most commonly recommended treatment for acute WAD. This contributes to the case for physiotherapists to deliver an early psychological intervention to patients with acute WAD who are otherwise at high risk of a poor outcome.

Pregabalin versus placebo in targeting pro-nociceptive mechanisms to prevent chronic pain after whiplash injury in at-risk individuals - a feasibility study for a randomised controlled trial

BACKGROUND

Whiplash-associated disorders (WAD) are an enormous and costly burden to Australian society. Up to 50% of people who experience a whiplash injury will never fully recover. Whiplash is resistant to treatment and no early management approach has yet been shown to prevent chronic pain. The early presence of central sensitization is associated with poor recovery. Pregabalin's effects on central sensitization indicate the potential to prevent or modulate these processes after whiplash injury and to improve health outcomes, but this has not been investigated. This paper describes the protocol for a feasibility study for a randomised controlled trial of pregabalin plus evidence-based advice compared to placebo plus evidence-based advice for individuals with acute whiplash injury who are at risk of poor recovery.

METHODS

This double blind, placebo-controlled randomised feasibility study will examine the feasibility and potential effectiveness of pregabalin and evidence-based advice (intervention) compared to placebo and evidence-based advice (control) for individuals with acute whiplash injury at risk of poor recovery. Thirty participants (15 per group) aged 18-65 years with Grade II WAD, within 48 hours of injury and currently experiencing at least moderate pain (NRS: ≥ 5/10) will be recruited from Emergency Departments of public hospitals in Queensland, Australia. Pregabalin will be commenced at 75 mg bd and titrated up to 300 mg bd as tolerated for 4 weeks followed by 1 week of weaning.

RESULTS

The feasibility of trial procedures will be tested, as well as the potential effect of the intervention on the outcomes. The primary outcome of neck pain intensity at 3 months from randomisation will be compared between the treatment groups using standard analysis of variance techniques.

DISCUSSION

Feasibility and potential effectiveness data will inform an appropriately powered full trial, which if successful, will provide an effective and cost-effective intervention for a costly and treatment resistant condition. It will also have implications for the early management of other traumatic conditions beyond whiplash.

Neck Pain: Revision 2017

The Orthopaedic Section of the American Physical Therapy Association (APTA) has an ongoing effort to create evidence-based practice guidelines for orthopaedic physical therapy management of patients with musculoskeletal impairments described in the World Health Organization's International Classification of Functioning, Disability, and Health (ICF). The purpose of these revised clinical practice guidelines is to review recent peer-reviewed literature and make recommendations related to neck pain.

Return to work helps maintain treatment gains in the rehabilitation of whiplash injury

This study examined the relation between return to work and the maintenance of treatment gains made over the course of a rehabilitation intervention. The study sample consisted of 110 individuals who had sustained whiplash injuries in rear collision motor vehicle accidents and were work-disabled at the time of enrolment in the study. Participants completed pre- and post-treatment measures of pain severity, disability, cervical range of motion, depression, posttraumatic stress symptoms, and catastrophizing. Pain severity was assessed again at 1-year follow-up. At 1-year follow-up, 73 participants had returned to work and 37 remained work-disabled. Analyses revealed that participants who returned to work were more likely to maintain treatment gains (77.5%) than participants who remained work-disabled (48%), χ = 6.3, P < 0.01. The results of a regression analysis revealed that the relation between return to work and the maintenance of treatment gains remained significant (β = 0.30, P < 0.01), even when controlling for potential confounders such as pain severity, restricted range of motion, depression, and pain catastrophizing. The Discussion addresses the processes by which prolonged work-disability might contribute to the failure to maintain treatment gains. Important knowledge gaps still remain concerning the individual, workplace, and system variables that might play a role in whether or not the gains made in the rehabilitation of whiplash injury are maintained. Clinical implications of the findings are also addressed.

Do Subjects with Whiplash-Associated Disorders Respond Differently in the Short-Term to Manual Therapy and Exercise than Those with Mechanical Neck Pain?

Objective

To compare the short-term effects of manual therapy and exercise on pain, related disability, range of motion, and pressure pain thresholds between subjects with mechanical neck pain and whiplash-associated disorders.

Methods

Twenty-two subjects with mechanical neck pain and 28 with whiplash-associated disorders participated. Clinical and physical outcomes including neck pain intensity, neck-related disability, and pain area, as well as cervical range of motion and pressure pain thresholds over the upper trapezius and tibialis anterior muscles, were obtained at baseline and after the intervention by a blinded assessor. Each subject received six sessions of manual therapy and specific neck exercises. Mixed-model repeated measures analyses of covariance (ANCOVAs) were used for the analyses.

Results

Subjects with whiplash-associated disorders exhibited higher neck-related disability ( P  = 0.021), larger pain area ( P  = 0.003), and lower pressure pain thresholds in the tibialis anterior muscle ( P  = 0.009) than those with mechanical neck pain. The adjusted ANCOVA revealed no between-group differences for any outcome (all P  > 0.15). A significant main effect of time was demonstrated for clinical outcomes and cervical range of motion with both groups experiencing similar improvements (all P  < 0.01). No changes in pressure pain thresholds were observed in either group after treatment ( P  > 0.222).

Conclusions

The current clinical trial found that subjects with mechanical neck pain and whiplash-associated disorders exhibited similar clinical and neurophysiological responses after a multimodal physical therapy intervention, suggesting that although greater signs of central sensitization are present in subjects with whiplash-associated disorders, this does not alter the response in the short term to manual therapy and exercises.

Three combinations of manual therapy techniques within naprapathy in the treatment of neck and/or back pain: a randomized controlled trial

Background

Manual therapy as spinal manipulation, spinal mobilization, stretching and massage are common treatment methods for neck and back pain. The objective was to compare the treatment effect on pain intensity, pain related disability and perceived recovery from a) naprapathic manual therapy (spinal manipulation, spinal mobilization, stretching and massage) to b) naprapathic manual therapy without spinal manipulation and to c) naprapathic manual therapy without stretching for male and female patients seeking care for back and/or neck pain.

Method

Participants were recruited among patients, ages 18–65, seeking care at the educational clinic of Naprapathögskolan - the Scandinavian College of Naprapathic Manual Medicine in Stockholm. The patients (n = 1057) were randomized to one of three treatment arms a) manual therapy (i.e. spinal manipulation, spinal mobilization, stretching and massage), b) manual therapy excluding spinal manipulation and c) manual therapy excluding stretching. The primary outcomes were minimal clinically important improvement in pain intensity and pain related disability. Treatments were provided by naprapath students in the seventh semester of eight total semesters. Generalized estimating equations and logistic regression were used to examine the association between the treatments and the outcomes.

Results

At 12 weeks follow-up, 64 % had a minimal clinically important improvement in pain intensity and 42 % in pain related disability. The corresponding chances to be improved at the 52 weeks follow-up were 58 % and 40 % respectively. No systematic differences in effect when excluding spinal manipulation and stretching respectively from the treatment were found over 1 year follow-up, concerning minimal clinically important improvement in pain intensity (p = 0.41) and pain related disability (p = 0.85) and perceived recovery (p = 0.98). Neither were there disparities in effect when male and female patients were analyzed separately.

Conclusion

The effect of manual therapy for male and female patients seeking care for neck and/or back pain at an educational clinic is similar regardless if spinal manipulation or if stretching is excluded from the treatment option.

Management of neck pain and associated disorders: A clinical practice guideline from the Ontario Protocol for Traffic Injury Management (OPTIMa) Collaboration

PURPOSE

To develop an evidence-based guideline for the management of grades I-III neck pain and associated disorders (NAD).

METHODS

This guideline is based on recent systematic reviews of high-quality studies. A multidisciplinary expert panel considered the evidence of effectiveness, safety, cost-effectiveness, societal and ethical values, and patient experiences (obtained from qualitative research) when formulating recommendations. Target audience includes clinicians; target population is adults with grades I-III NAD <6 months duration.

RECOMMENDATION 1

Clinicians should rule out major structural or other pathologies as the cause of NAD. Once major pathology has been ruled out, clinicians should classify NAD as grade I, II, or III.

RECOMMENDATION 2

Clinicians should assess prognostic factors for delayed recovery from NAD.

RECOMMENDATION 3

Clinicians should educate and reassure patients about the benign and self-limited nature of the typical course of NAD grades I-III and the importance of maintaining activity and movement. Patients with worsening symptoms and those who develop new physical or psychological symptoms should be referred to a physician for further evaluation at any time during their care.

RECOMMENDATION 4

For NAD grades I-II ≤3 months duration, clinicians may consider structured patient education in combination with: range of motion exercise, multimodal care (range of motion exercise with manipulation or mobilization), or muscle relaxants. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, strain-counterstrain therapy, relaxation massage, cervical collar, electroacupuncture, electrotherapy, or clinic-based heat.

RECOMMENDATION 5

For NAD grades I-II >3 months duration, clinicians may consider structured patient education in combination with: range of motion and strengthening exercises, qigong, yoga, multimodal care (exercise with manipulation or mobilization), clinical massage, low-level laser therapy, or non-steroidal anti-inflammatory drugs. In view of evidence of no effectiveness, clinicians should not offer strengthening exercises alone, strain-counterstrain therapy, relaxation massage, relaxation therapy for pain or disability, electrotherapy, shortwave diathermy, clinic-based heat, electroacupuncture, or botulinum toxin injections.

RECOMMENDATION 6

For NAD grade III ≤3 months duration, clinicians may consider supervised strengthening exercises in addition to structured patient education. In view of evidence of no effectiveness, clinicians should not offer structured patient education alone, cervical collar, low-level laser therapy, or traction. RECOMMENDATION 7: For NAD grade III >3 months duration, clinicians should not offer a cervical collar. Patients who continue to experience neurological signs and disability more than 3 months after injury should be referred to a physician for investigation and management. RECOMMENDATION 8: Clinicians should reassess the patient at every visit to determine if additional care is necessary, the condition is worsening, or the patient has recovered. Patients reporting significant recovery should be discharged.

Effects of Neck-Specific Exercises Compared to Waiting List for Individuals With Chronic Whiplash-Associated Disorders: A Prospective, Randomized Controlled Study

OBJECTIVE

To determine whether 3 months of neck-specific exercises (NSEs) could benefit individuals with chronic whiplash-associated disorder (WAD) who were on a waiting list (WL) for treatment.

DESIGN

A prospective, randomized controlled study.

SETTING

Primary health care.

PARTICIPANTS

Individuals (N=41; 31 women, 10 men; mean age ± SD, 38±11.2y) with chronic (6-36mo) WAD, grades 2 and 3, were analyzed.

INTERVENTIONS

Patients were randomly assigned to NSEs or no treatment for 3 months.

MAIN OUTCOME MEASURES

Neck-specific disability (Neck Disability Index [NDI]), neck pain (visual analog scale), general pain-related disability (Pain Disability Index [PDI]), self-perceived performance ability (Self-Efficacy Scale [SES]), and health-related quality of life (EuroQol 5 dimensions [EQ-5D]) were measured.

RESULTS

NSEs significantly improved the NDI, SES, and EQ-5D compared with WL (P<.01). There was significant improvement (P<.0001) over time in all outcomes for NSEs, and apart from the PDI, significant worsening (P=.002-.0002) over time for the untreated group.

CONCLUSIONS

NSEs were more beneficial than no intervention while on a WL for individuals with chronic WAD.
