Conservative interventions provide short-term relief for non-specific neck pain: a systematic review

Durable Effect of Acupuncture for Chronic Neck Pain: A Systematic Review and Meta-Analysis

OBJECTIVE

Chronic neck pain, a prevalent health concern characterized by frequent recurrence, requires exploration of treatment modalities that provide sustained relief. This systematic review and meta-analysis aimed to evaluate the durable effects of acupuncture on chronic neck pain.

METHODS

We conducted a literature search up to March 2024 in six databases, including PubMed, Embase, and the Cochrane Library, encompassing both English and Chinese language publications. The main focus of evaluation included pain severity, functional disability, and quality of life, assessed at least 3 months post-acupuncture treatment. The risk of bias assessment was conducted using the Cochrane Risk of Bias 2.0 tool, and meta-analyses were performed where applicable.

RESULTS

Eighteen randomized controlled trials were included in the analysis. Acupuncture as an adjunct therapy could provide sustained pain relief at three (SMD: - 0.79; 95% CI - 1.13 to - 0.46; p < 0.01) and six (MD: - 18.13; 95% CI - 30.18 to - 6.07; p < 0.01) months post-treatment. Compared to sham acupuncture, acupuncture did not show a statistically significant difference in pain alleviation (MD: - 0.12; 95% CI - 0.06 to 0.36; p = 0.63). However, it significantly improved functional outcomes as evidenced by Northwick Park Neck Pain Questionnaire scores 3 months post-treatment (MD: - 6.06; 95% CI - 8.20 to - 3.92; p < 0.01). Although nine studies reported an 8.5%-13.8% probability of adverse events, these were mild and transitory adverse events.

CONCLUSION

Acupuncture as an adjunct therapy may provide post-treatment pain relief lasting at least 3 months for patients with chronic neck pain, although it is not superior to sham acupuncture, shows sustained efficacy in improving functional impairment for over 3 months, with a good safety profile.

Effect of long-term cervical extensor exercise program on functional disability, pain intensity, range of motion, cervical muscle mass, and cervical curvature in young adult population with chronic non-specific neck pain: a randomized controlled trial

BACKGROUND

The prevalence of chronic non-specific neck pain (CNNP) is on the rise among the young adult population. We herein aimed to compare the effects of long-term specific cervical extensor training and stretching exercises on improving this chronic disorder in young adults.

METHODS

In this prospective, randomized, controlled study, 70 participants aged 18-35 years with CNNP and cervical lordosis loss were included. The participants were assigned to undergo either specific cervical extensor training (observation group) or perform usual stretching exercises (control group). The exercise duration was set at 12 months, with 9 months at the clinic and 3 months at home. The outcome assessments included changes in the neck disability index, visual analog scale from baseline, cervical range of motion (CROM), cross-sectional areas (CSAs) of cervical extensors, and cervical curvature from baseline. The outcome measures were compared between groups at 3, 6, and 12 months of follow-up.

RESULTS

All 70 participants underwent randomization, and no significant differences in demographics and baseline data were found between the two groups. The observation group showed a greater improvement in neck disability index and visual analog scale scores at the 12-month follow-up than the control group. Additionally, a more substantial increase in CROM and CSAs of cervical extensors was observed in the observation group at the 6-month and 12-month follow-ups (P < 0.05). Although more participants in the observation group achieved cervical lordosis at the 12-month follow-up, the difference was marginally nonsignificant (9% in the control group vs. 28% in the observation group, P = 0.075).

CONCLUSIONS

In young adults with CNNP, long-term specific cervical extensor training was associated with a more significant clinically meaningful improvement in disability, pain, and CROM than stretching exercises. The increased CSAs of cervical extensors may potentially contribute to the restoration of cervical lordosis.

Effects of a Therapeutic Exercise Protocol for Patients with Chronic Non-Specific Back Pain in Primary Health Care: A Single-Group Retrospective Cohort Study

BACKGROUND

Back pain is highly prevalent; in Spain, it produces a very high economic cost and the scientific evidence supporting treatments shows low to moderate evidence for exercise. Therefore, the aim of this study was to assess the effectiveness of a therapeutic group exercise protocol in reducing pain intensity and disability in patients with back pain in primary health care setting.

METHODS

A total sample of 149 patients who suffered from chronic non-specific back pain was selected. Patients received a therapeutic exercise protocol, including auto-mobilization exercises for the neck and lumbar regions, as well as core stabilization exercises. Pain intensity and disability were evaluated before and after the therapeutic exercise protocol.

RESULTS

Statistically significant differences (p < 0.05) were shown in pain intensity and disability for patients with non-specific neck and low-back pain, with an effect size from moderate to large.

CONCLUSIONS

A therapeutic exercise protocol may provide beneficial effects upon disability and pain intensity in patients with chronic non-specific back pain, including neck and low-back pain conditions In addition, It could be considered for inclusion as a back-pain-approach program in primary healthcare.

Reductions in kinesiophobia and distress after pain neuroscience education and exercise lead to favourable outcomes: a secondary mediation analysis of a randomized controlled trial in primary care

ABSTRACT

Pain neuroscience education combined with exercise (PNE + exercise) is an effective treatment for patients with chronic spinal pain. Yet, however, little is known about its underlying therapeutic mechanisms. Thus, this study aimed to provide the first insights by performing a novel mediation analysis approach in a published randomized controlled trial in primary care where PNE + exercise was compared with standard physiotherapy. Four mediators (catastrophizing, kinesiophobia, central sensitization-related distress, and pain intensity) measured at postintervention and 3 outcomes (disability, health-related quality of life, and pain medication intake) measured at 6-month follow-up were included into the analysis. The postintervention measure of each outcome was also introduced as a competing candidate mediator in each respective model. In addition, we repeated the analysis by including all pairwise mediator-mediator interactions to allow the effect of each mediator to differ based on the other mediators' values. Postintervention improvements in disability, medication intake, and health-related quality of life strongly mediated PNE + exercise effects on each of these outcomes at 6-month follow-up, respectively. Reductions in disability and medication intake were also mediated by reductions in kinesiophobia and central sensitization-related distress. Reductions in kinesiophobia also mediated gains in the quality of life. Changes in catastrophizing and pain intensity did not mediate improvements in any outcome. The mediation analyses with mediator-mediator interactions suggested a potential effect modification rather than causal independence among the mediators. The current results, therefore, support the PNE framework to some extent as well as highlight the need for implementing the recent approaches for mediation analysis to accommodate dependencies among the mediators.

Protocol for the development of a 'trustworthy' living systematic review and meta analyses of manual therapy interventions to treat neuromusculoskeletal impairments

BACKGROUND

Preprocessed research resources are believed to be highly 'trustworthy' when translating research to clinical practice. However, the overall 'trustworthiness' is unknown if this evidence contains randomized clinical trials (RCTs) where prospective has not been/cannot be verified, has low confidence in estimated effects, and if they are not up to date.

OBJECTIVES

This protocol will be used to create a baseline benchmark for a series of trustworthy living systematic reviews (SRs) regarding manual therapy interventions.

METHODS

Data will originate from RCTs related to manual therapy neuromusculoskeletal interventions, indexed in 6 search engines in English from 1 January 2010, to the present. Two blinded reviewers will identify the RCTs and extract data using Covidence. The data will be synthesized based on consensus and analyzed using the Cochrane collaboration's Review Manager.

EXPECTED OUTCOMES

It is expected that there will be a shortage of RCTs with at least a moderate confidence in estimated effects that will allow for strong practice recommendations.

DISCUSSION

Identifying evidence that can be translated into strong practice recommendations is essential to identify beneficial and harmful interventions, decrease practice variability, and identify neuromusculoskeletal manual therapy interventions that require further disciplined methodological focus.

Manual therapy for non-radicular cervical spine related impairments: establishing a 'Trustworthy' living systematic review and meta-analysis

OBJECTIVES

To establish a 'trustworthy' living systematic review (SR) with a meta-analysis of manual therapy for treating non-radicular cervical impairments.

DESIGN

SR with meta-analysis.

LITERATURE SEARCH

Articles published between January 2010 and September 2022 were included from: Cochrane Central Register of Controlled Trials (CENTRAL); CINAHL; MEDLINE; PubMed; PEDro, and ProQuest Nursing and Allied Health.

METHODS

This SR included English-language randomized clinical trials (RCTs) of manual therapy involving adults used to treat non-radicular cervical impairments. The primary outcomes were pain and region-specific outcome measures. Cervicogenic headaches and whiplash were excluded to improve homogeneity. Two reviewers independently assessed RCTs. The prospective plan was to synthesize results with high confidence in estimated effects using GRADE.

RESULTS

Thirty-five RCTs were screened for registration status. Twenty-eight were not registered or registered prospectively. In 5 studies, the discussion and conclusion did not match the registry, or this could not be determined. One study did not meet the external validity criterion, and another was rated as having a high risk of bias. One study met the inclusion and exclusion criteria, so practice recommendations could not be made. The remaining study did not identify any clinically meaningful group differences.

DISCUSSION

Only one prospectively registered RCT met this SR's strict, high-quality standards. The single identified paper provides initial high-quality evidence on this topic.

CONCLUSION

This SR establishes a foundation of trustworthiness and can be used to generate research agendas to determine the potential clinical utility of manual therapy directed at the cervical spine for non-radicular cervical complaints.

Effects of Cervical Spine Exercise Protocol on Neck Pain, Pericervical Muscle Endurance, and Range of Motion in Medical Students: A Prospective Study

Introduction

Neck pain is a common and debilitating ailment that places a significant burden on the healthcare system. No practical protocols have been published utilizing a portable, commercially available, and affordable device that significantly reduces acute and chronic neck pain.

Methods

Forty-six young adults with or without mild-to-moderate neck pain completed a six-week neck stretching and strengthening protocol with a portable cervical stretching and strengthening device. The primary outcome was changes to pericervical muscle endurance. Secondary outcomes were changes to cervical range of motion (ROM), neck length, circumference, and subjective pain, flexibility, and strength. Measurements were obtained on study days 0, 21, and 42.

Results

A significant increase in pericervical muscle endurance was demonstrated across all planes of cervical motion, ranging from 84% to 105%. Cervical ROM improved across all planes of motion but was only significant in right-side bending (5.3°), left rotation (6.2°), and right rotation (7.8°). Subjective pain evaluated via the Numeric Rating Scale (NRS) saw statistically significant improvement as well (1.33 to 0.51). Subjective assessment of participant cervical pain, strength, and flexibility improved 61.3%, 95.7%, and 97.8%, respectively.

Conclusions

A six-week pericervical muscle stretching and strengthening program increased pericervical endurance and ROM in young adults. Decreased cervical pain was seen using the NRS and modified pain scale across most participants.

Effect of post-isometric relaxation versus myofascial release therapy on pain, functional disability, rom and qol in the management of non-specific neck pain: a randomized controlled trial

Background

Non-specific neck pain is the most prevailing musculoskeletal disorder which has a large socioeconomic burden worldwide. It is associated with poor posture and neck strain which may lead to pain and restricted mobility. Physical therapists treat such patients through several means. Post isometric relaxation and Myofascial release therapy are used in clinical practice with little evidence to be firmed appropriately. So, this study was conducted to explore the effect of Post-isometric relaxation in comparison to Myofascial release therapy for patients having non-specific neck pain.

Methodology

Sixty patients were randomly allocated to Post isometric group and the Myofascial group. The treatment period was of 2 weeks. All the patients were evaluated using the Visual analogue scale (VAS), Neck disability index (NDI), Universal Goniometer, and WHO BREF Quality of life-100 in the 1st and 6th sessions. Recorded data was entered on SPSS 21. Data were examined using two-way repeated ANOVA to measure the variance of analysis (group x time).

Results

Analysis of the baseline characteristics revealed that both groups were homogenous in terms of age and gender i.e. a total of 60 participants were included in this research study 30 in each group. Out of 60 patients, there were 20(33.3%) males and 40(66.7%) females with a mean age of 32.4(5.0) years. Participants in the Post Isometric group demonstrated significant improvements (p < 0.025) in VAS, NDI, Cervical Extension, left side rotation ranges, and QoL (Social Domain) at the 2-week follow-up compared with those in the Myofascial group. In addition, the Myofascial group indicated significantly better improvement in the mean score of CROM (flexion and right and left side bending).

Conclusion

The study demonstrated patients with nonspecific neck pain can benefit from the post isometric relaxation with significant improvement in pain, disability, cervical ROM, and Quality of life compared with myofascial release therapy.

Effectiveness of Specific Neck Exercise for Nonspecific Neck Pain; Usefulness of Strategies for Patient Selection and Tailored Exercise-A Systematic Review With Meta-Analysis

OBJECTIVE

Specific neck exercises (SNE) targeting deep cervical flexors and extensors are commonly used for the treatment of nonspecific neck pain (NSNP). However, whether SNE are more effective than alternative exercise interventions (AEI) remains unclear. Furthermore, it has been postulated that SNE may be most effective when they are tailored and targeted to patients with evidence of motor control dysfunction, yet this notion also remains unproven. The objectives of this study were to compare the effectiveness of SNE with that of AEI for reducing pain and disability in people with NSNP and to assess whether the effectiveness of SNE is increased when the exercises are tailored and provided to patients with evidence of motor control dysfunction.

METHODS

For this systematic review with meta-analysis, Medline, Web of Science, Scopus, and Physiotherapy Evidence Database were searched. Eligibility criteria included randomized controlled trials evaluating the effectiveness of SNE against that of AEI in people with NSNP. Meta-analysis included subgroup analyses to determine the effect of exercise tailoring and participant selection criteria on the effectiveness of SNE.

RESULTS

Twelve studies were included. Meta-analysis revealed greater effectiveness of SNE in the short to medium term for reducing pain (pooled standardized mean difference [SMD] = -0.41; 95% CI = -0.76 to -0.06; P = .02) and disability (pooled SMD = -0.41; 95% CI = -0.78 to -0.04; P = .03) but no differences in the long term for pain (pooled SMD = -1.30; 95% CI = -3.35 to 0.75; P = .21) and disability (pooled SMD = -1.81; 95% CI = -4.29 to 0.67; P = .15), although evidence was limited for the latter. The effectiveness of SNE was not superior in studies that included only participants with motor control dysfunction or when exercises were tailored to each participant. Overall, the studies were of low quality. Grading of Recommendations Assessment, Development and Evaluation revealed low certainty, serious risk of bias, and inconsistency of findings for short- to medium-term effects and very low certainty, serious risk of bias, and very serious inconsistency for long-term effects.

CONCLUSION

The preferential use of SNE may be recommended to achieve better short- to medium-term outcomes, although the low quality of evidence affects the certainty of these findings. Currently used strategies for selecting patients and tailoring SNE are not supported by the evidence and therefore cannot be recommended for clinical practice.

IMPACT

SNE are more effective than AEI for reducing pain and disability in patients with NSNP in the short to medium term, but overall evidence is of low quality, affecting the certainty of the findings. Tests of muscle dysfunction (mostly the craniocervical flexion test) currently used in studies to select patients and tailor SNE do not result in greater effectiveness of these exercises.

LAY SUMMARY

Evidence suggests SNE are more effective than other forms of exercise, although evidence is overall of low quality. Use of the craniocervical flexion test in isolation to select participants and/or tailor SNE cannot be recommended.

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.

Transcutaneous electrical stimulation in neck pain: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

The objective of this systematic review was to investigate the effectiveness of electrical stimulation (ES) for neck pain (NP).

DATABASES AND DATA TREATMENT

The databases CINAHL, Embase, MEDLINE (via OVID), PEDro and Web of Science were searched, with no date restrictions. Two independent reviewers selected randomized controlled trials (RCTs) reporting pain, range of motion or psychosocial factors in people with NP, in which ES was applied. Methodological quality was assessed using the PEDro scale. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) was used to evaluate the quality of evidence. Thirty studies met eligibility criteria.

RESULTS

Main results showed evidence of moderate quality that ES combined with other intervention significantly decreases the pain intensity compared to other intervention immediately post-treatment and at short-term follow-up; evidence of low quality showed significant effects of ES combined with other intervention in decreasing neck disability compared to other intervention immediately post-treatment; evidence of very-low quality that ES increased the pressure pain threshold compared to placebo immediately post-treatment and that ES + other intervention also increased the pressure pain threshold compared to other intervention at short-term follow-up.

CONCLUSIONS

ES combined with other intervention seems to be useful to relieve pain and to improve disability in people with NP, however, more studies are needed.

SIGNIFICANCE

Electrical stimulation seems to be effective for improving pain intensity, immediately post-treatment in people with neck pain, mainly as an adjunct therapeutic modality. Nevertheless, high-quality RCTs are still needed to investigate the efficacy of electrical stimulation in neck pain.

Cervical movement kinematic analysis in patients with chronic neck pain: A comparative study with healthy subjects

BACKGROUND

Several studies have investigated cervical kinematic performance in patients with chronic neck pain, especially with fast movements. A recent systematic review recommended further study of cervical spine kinematics cervical motions in individuals with neck pain.

OBJECTIVES

This study aimed to examine cervical spine kinematics of naturally paced cervical motions in patients with chronic neck pain compared with a group of asymptomatic participants. Also, the relationships between cervical kinematic measures with neck pain intensity and disability were determined.

METHOD

Kinematic performance was measured in 20 individuals with chronic nonspecific neck pain and 20 healthy controls. Data were captured using a 7-camera motion analysis system. Parameters were range of cervical motion, peak velocity, duration of movement, and jerk index (smoothness of movement). Pain intensity and Neck Disability Index were also measured.

RESULTS

Duration of movements, peak velocities, and jerk indexes were significantly different between the two groups (p < 0.05). Pain intensity was significantly associated with duration of movement, range of motion, peak velocity, and smoothness predominantly in extension (r range = 0.4 to 0.6, p < 0.05).

CONCLUSION

This study's findings indicated altered cervical kinematic performance during naturally paced motions (particularly reduced smoothness of movement)in patients with chronic nonspecific neck pain compared to asymptomatic participants. Also, pain intensity was moderately associated with most kinematic measures, especially in extension. This study's results can help to understand better the impairments associated with chronic nonspecific neck pain.

The contemporary management of neck pain in adults

Neck pain is a common condition with a high prevalence worldwide. Neck pain is associated with significant levels of disability and is widely considered an important public health problem. Neck pain is defined as pain perceived between the superior nuchal line and the spinous process of the first thoracic vertebra. In some types of neck conditions, the pain can be referred to the head, trunk and upper limbs. This article aims to provide an overview of the available evidence on prevalence, costs, diagnosis, prognosis, risk factors, prevention and management of patients with neck pain.

Approaches to cervical spine mobilization for neck pain: a pilot randomized controlled trial

Study design

Pilot randomized controlled trial.

Background

Better understanding of the relative effectiveness of different approaches to cervical spine mobilization has been identified as a research priority in manual therapy practice. Two distinct approaches to the practice of mobilization have emerged in recent years, based on different reasoning models for selection of mobilization techniques. The objective of this pilot study was to assess feasibility aspects for a future randomized clinical trial by exploring short-term pain and disability outcomes after a single treatment with pragmatic versus prescriptive approaches to cervical mobilization for people with recent-onset neck pain at 48-h follow-up after randomization.

Methods

Twenty adults with a new episode of mechanical neck pain were randomly allocated to either pragmatic or prescriptive mobilization intervention groups. The pragmatic group received a single treatment of cervical mobilization with the technique, target segment, and grade selected by their treating therapist. The prescriptive group received a single treatment of standardized mobilization with techniques similar to a previous mobilization clinical trial. Feasibility outcomes were recruitment rates, randomization audit and completion of treatment and follow-up per protocol. The primary clinical outcome of interest was disability level measured at 48-h follow-up after randomization.

Results

Recruitment rates were approximately 2.5 participants per week and 100% of eligible participants were deemed suitable for treatment with cervical mobilization. There was sufficient variety in the range of pragmatic treatments selected and the data collection process imposed minimal burden on participants.

Conclusions

Our results provide supporting evidence for the feasibility of a future larger scale randomized clinical trial.

Comparison of high-intensity laser therapy and combination of ultrasound treatment and transcutaneous nerve stimulation on cervical pain associated with cervical disc herniation: A randomized trial

The aim of the study was to compare the effect of high-intensity laser therapy (HILT) and a combination of transcutaneous nerve stimulation (TENS) and ultrasound (US) treatment on pain, range of motion (ROM) and functional activity on cervical pain associated with cervical disc herniation (CDH). A total of 40 patients (22 women and 18 men) affected by CDH were enrolled in this study. Patients were randomly divided into two groups. In group 1 (20 subjects), patients received 20 sessions of HILT plus exercise, while in group 2 (20 subjects), a combination of US, TENS and exercise were applied. The outcomes were cervical segment ROM, pain level measured by visual analogue scale (VAS), and functional activity measured by neck pain and disability scale (NPADS) before and after the therapy. The level of statistical significance was set as p < 0.05. There was no difference for cervical ROM, VAS and NPADS values between the groups at the baseline (p> 0.05). After the treatment, cervical ROM, VAS and NPADS values were significantly improved in both groups (p < 0.05). When the groups were compared in terms of post treatment VAS, NPADS and ROM values, no statistical significance was found between the two groups (p> 0.05). Both of therapeutic modalities demonstrated analgesic efficacy and improved the function in patients affected by CDH after 4 weeks of therapy (total 20 treatment sessions in 5 days a week). Both the HILT plus exercise program and the TENS / US plus exercise program were found to be effective in improving cervical range of motion and quality of life by reducing pain. These two treatment programs have similar effects in the treatment of cervical pain associated with CDH and can be used as an alternative to each other in clinical applications. However; It is clear that futher studies are needed to investigate the principles of application of HILT to painful areas or tissues (amount of area applied, dose applied, energy delivered, number of pulses, duration of session, frequency of sessions) and to exclude the effects of exercise treatment on the results of both treatment groups.

Transcutaneous electrical nerve stimulation (TENS) for chronic neck pain

BACKGROUND

Chronic neck pain is a highly prevalent condition, affecting 10% to 24% of the general population. Transcutaneous electrical nerve stimulation (TENS) is the noninvasive, transcutaneous use of electrical stimulation to produce analgesia. It is a simple, low-cost and safe intervention used in clinical practice as an adjunct treatment for painful musculoskeletal conditions that have a considerable impact on daily activities, such as chronic neck pain. This review is a split from a Cochrane Review on electrotherapy for neck pain, published in 2013, and focuses specifically on TENS for chronic neck pain.

OBJECTIVES

To evaluate the effectiveness of transcutaneous electrical nerve stimulation (TENS) (alone or in association with other interventions) compared with sham and other clinical interventions for the treatment of chronic neck pain.

SEARCH METHODS

We searched Cochrane Back and Neck Trials Register, CENTRAL, MEDLINE, Embase, five other databases and two trials registers to 9 November 2018. We also screened the reference lists of relevant studies to identify additional trials. There were no language, source, or publication date restrictions.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) involving adults (≥ 18 years of age) with chronic neck pain (lasting > 12 weeks) that compared TENS alone or in combination with other treatments versus active or inactive treatments. The primary outcomes were pain, disability and adverse events.

DATA COLLECTION AND ANALYSIS

Two independent review authors selected the trials, extracted data and assessed the risk of bias of included studies. A third review author was consulted in case of disagreements. We used the Cochrane 'Risk of bias' tool (adapted by Cochrane Back and Neck), to assess the risk of bias of individual trials and GRADE to assess the certainty of evidence. We used risk ratios (RRs) to measure treatment effects for dichotomous outcomes, and mean differences (MDs) for continuous outcomes, with their respective 95% confidence intervals (CIs).

MAIN RESULTS

We included seven RCTs with a total of 651 participants, mean age 31.7 to 55.5 years, conducted in three different countries (Turkey, Jordan and China). The length of follow-up ranged from one week to six months. Most RCTs used continuous TENS, with a frequency of 60 Hz to 100 Hz, pulse width of 40 μs to 250 μs and tolerable intensity, described as a tingling sensation without contraction, in daily sessions lasting 20 to 60 minutes. Due to heterogeneity in interventions and outcomes, we did not pool individual study data into meta-analyses. Overall, we judged most studies as being at low risk for selection bias and high risk for performance and detection bias. Based on the GRADE approach, there was very low-certainty evidence from two trials about the effects of conventional TENS when compared to sham TENS at short-term (up to 3 months after treatment) follow-up, on pain (assessed by the Visual Analogue Scale (VAS)) (MD -0.10, 95% CI -0.97 to 0.77) and the percentage of participants presenting improvement of pain (RR 1.57, 95% CI 0.84 to 2.92). None of the included studies reported on disability or adverse events.

AUTHORS' CONCLUSIONS

This review found very low-certainty evidence of a difference between TENS compared to sham TENS on reducing neck pain; therefore, we are unsure about the effect estimate. At present, there is insufficient evidence regarding the use of TENS in patients with chronic neck pain. Additional well-designed, -conducted and -reported RCTs are needed to reach robust conclusions.

Addition of a new three-dimensional adjustable cervical thoracic orthosis to a multi-modal program in the treatment of nonspecific neck pain: study protocol for a randomised pilot trial

BACKGROUND

Nonspecific neck pain (NSNP) is one of the most common musculoskeletal problems treated by orthopaedic physicians and physiotherapists. Posture has emerged as one of the major risk factors associated with NSNP, but most previous studies ignored correct posturing as an effective treatment. Therefore, one of the major challenges faced by clinicians is how to incorporate 3D posture findings into the treatment plane. The present study will evaluate the feasibility of conducting a larger randomized trial. This pilot study is designed to investigate the hypothesis that a multimodal programme supplemented with the addition of a 3D adjustable cervico thoracic posture corrective orthotic (CTPCO) will yield short- and long-term improvement on NSNP management outcomes.

METHODS/DESIGN

This pilot, single-blind, randomized controlled trial will divide 24 patients into two groups (study and control) using block randomization. Both groups will receive conventional treatment consisting of a moist hot pack, soft tissue mobilization, manual therapy and therapeutic exercise. The study group will undergo ambulatory mirror-image functional re-training wearing a 3D adjustable CTPCO. The primary outcome is feasibility, including recruitment (e.g., time to complete enrolment, recruitment rate), patient retention and adherence to treatment allocation (e.g., session attendance, home practice, use of non-study treatments). The secondary outcomes used to assess the effectiveness of the treatment will include neck pain (measures using the visual analogue scale (VAS)) and neck disability (measures using the neck disability index (NDI)), among other outcome measures, compared between the experimental and control groups. Three-dimensional posture parameters of head measurements will be provided by a Global Posture System (GPS). The outcome measures for determining the treatment effect will be assessed at three intervals: pre-treatment, after 10 weeks of intervention and after 3 months at follow-up.

DISCUSSION

This randomized controlled pilot trial will inform the design of a future full-scale trial. The outcomes will provide some resources for the incorporation of ambulatory mirror-image functional re-training intervention compared to a control group intervention for neck pain, disability and 3D posture parameters.

Effect of specific deep cervical muscle exercises on functional disability, pain intensity, craniovertebral angle, and neck-muscle strength in chronic mechanical neck pain: a randomized controlled trial

Background

Exercise is known to be an important component of treatment programs for individuals with neck pain. The study aimed to compare the effects of semispinalis cervicis (extensor) training, deep cervical flexor (flexor) training, and usual care (control) on functional disability, pain intensity, craniovertebral (CV) angle, and neck-muscle strength in chronic mechanical neck pain.

Methods

A total of 54 individuals with chronic mechanical neck pain were randomly allocated to three groups: extensor training, flexor training, or control. A Thai version of the Neck Disability Index, numeric pain scale (NPS), CV angle, and neck-muscle strength were measured at baseline, immediately after 6 weeks of training, and at 1- and 3 -month follow-up.

Results

Neck Disability Index scores improved significantly more in the exercise groups than in the control group after 6 weeks training and at 1- and 3-month follow-up in both the exten-sor (P=0.001) and flexor groups (P=0.003, P=0.001, P=0.004, respectively). NPS scores also improved significantly more in the exercise groups than in the control group after 6 weeks’ training in both the extensor (P<0.0001) and flexor groups (P=0.029. In both exercise groups, the CV angle improved significantly compared with the control group at 6 weeks and 3 months (extensor group, P=0.008 and P=0.01, respectively; flexor group, P=0.002 and 0.009, respectively). At 1 month, the CV angle had improved significantly in the flexor group (P=0.006). Muscle strength in both exercise groups had improved significantly more than in the control group at 6 weeks and 1- and 3-month follow-up (extensor group, P=0.04, P=0.02, P=0.002, respectively; flexor group, P=0.002, P=0.001, and 0.001, respectively). The semispinalis group gained extensor strength and the deep cervical flexor group gained flexor strength.

Conclusion

The results suggest that 6 weeks of training in both exercise groups can improve neck disability, pain intensity, CV angle, and neck-muscle strength in chronic mechanical neck pain.

Overview of Treatment Guidelines and Clinical Practical Guidelines That Recommend the Use of Acupuncture: A Bibliometric Analysis

INTRODUCTION

As positive evidence emerges for the use of an intervention to treat a health problem, the intervention gradually becomes incorporated into treatment guidelines (TGs) or clinical practice guidelines (CPGs) that are related to that health problem. To assess whether this general hypothesis can apply to acupuncture, 96 health problems were identified for which positive conclusions in systematic reviews and meta-analyses regarding the effectiveness of acupuncture have been made and then searched for TGs or CPGs that have recommended the use of acupuncture.

METHODS

Through August 31, 2017, searches were performed in relevant medical databases and Google using "treatment guideline," "clinical practice guideline," and the names of the 96 medical conditions as search terms. A "snow-balling" search approach was adopted. All positive recommendations were added into the registry.

RESULTS

A total of 1311 publications were found that recommended using acupuncture published between 1991 and 2017. The number per year reached 50 in 2005 and 100 in 2009. In addition, 2189 positive recommendations were found for the use of acupuncture. Of these, 1486 were related to 107 pain indications and 703 were related to 97 nonpain indications. These recommendations were made by a wide range of groups, such as government health institutions, national guideline, and medical specialty groups. The recommendations came from around the world but were especially abundant in North America, Europe, and Australasia.

DISCUSSION AND CONCLUSION

Considerably more recommendations were found for the use of acupuncture than are known within the acupuncture or medical communities. A trend by year was also found; a rise in the number of positive statements about acupuncture was typically followed by a rise in the number of recommendations of acupuncture. Thus, the recommendations followed the emergent evidence for acupuncture. Better implementation plans need to be developed for the CPG/TG recommendations about acupuncture to be more effective/efficient.

Pain management using a multimodal physiotherapy program including a biobehavioral approach for chronic nonspecific neck pain: a randomized controlled trial

Objective: To determine the effectiveness of a therapeutic patient education (TPE) intervention based on a biobehavioral approach combined with manual therapy (MT) to reduce pain in patients with chronic nonspecific neck pain (CNSNP). In addition, this study intended to assess the effectiveness of a multimodal physiotherapy program including TPE to reduce pain in patients with CNSNP. Design: Single-blind randomized controlled trial. Interventions: A total of 47 patients with CNSNP were randomized into three groups: (1) MT (control group); (2) MT plus TPE based on a biobehavioral approach (Exp1); and (3) MT plus TPE based on a biobehavioral approach, and therapeutic exercise (Exp2). Main Outcome Measurements: The clinical outcomes were recorded at baseline and at 1 and 4 months after the initiation of treatment. The primary outcome was pain intensity (Visual Analog Scale), and the secondary outcomes were pain catastrophizing (Pain Catastrophizing Scale), illness severity and global improvement (Clinical Global Impression Scale), and mechanosensitivity of the median nerve (Upper Limb Neural Test) and the cervical region (Modified Passive Neck Flexion Test). Results: Statistically significant differences in pain intensity were found when Exp2 was compared with Exp1 and the control group at 4 months (p = 0.015 and p = 0.001, respectively), but no difference was found between Exp1 and the control group at the same follow-up period (p = 0.86). Exp2 showed statistically significant differences in all of the secondary outcomes except for pain catastrophizing when compared with the control group at 4 months. Conclusions: The Exp2 group was more effective than Exp1 and the control group in terms of reducing pain intensity at 4 months; at post-treatment, only Exp2 was more effective than the control group.

PNF and manual therapy treatment results of patients with cervical spine osteoarthritis

PURPOSE

The aim of this study was to evaluate the effectiveness of PNF and manual therapy methods in the treatment of patients with cervical spine osteoarthritis, especially their efficacy in reducing pain and improving functionality in everyday life. Long-term results were also compared in order to determine which method of treatment is more effective.

SUBJECTS AND METHODS

Eighty randomly selected females aged 45-65 were included in the study. They were randomly divided into two groups of 40 persons. One group received PNF treatment and the other received manual therapy (MAN.T). To evaluate functional capabilities, the Functional Rating Index was used. To evaluate changes in pain, a shortened version of the McGill Questionnaire was used.

RESULT

The PNF group achieved a greater reduction in pain than the MAN.T group. The PNF group showed a greater improvement in performing daily activities such as sleeping, personal care, travelling, work, recreation, lifting, walking and standing as well as decreased intensity and frequency of pain compared to the MAN.T group.

CONCLUSION

The PNF method proved to be more effective in both short (after two weeks) and long (after three months) term.

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.

Non-steroidal anti-inflammatory drugs for spinal pain: a systematic review and meta-analysis

BACKGROUND

While it is now clear that paracetamol is ineffective for spinal pain, there is not consensus on the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) for this condition. We performed a systematic review with meta-analysis to determine the efficacy and safety of NSAIDs for spinal pain.

METHODS

We searched MEDLINE, EMBASE, CINAHL, CENTRAL and LILACS for randomised controlled trials comparing the efficacy and safety of NSAIDs with placebo for spinal pain. Reviewers extracted data, assessed risk of bias and evaluated the quality of evidence using the Grade of Recommendations Assessment, Development and Evaluation approach. A between-group difference of 10 points (on a 0-100 scale) was used for pain and disability as the smallest worthwhile effect, as well as to calculate numbers needed to treat. Random-effects models were used to calculate mean differences or risk ratios with 95% CIs.

RESULTS

We included 35 randomised placebo-controlled trials. NSAIDs reduced pain and disability, but provided clinically unimportant effects over placebo. Six participants (95% CI 4 to 10) needed to be treated with NSAIDs, rather than placebo, for one additional participant to achieve clinically important pain reduction. When looking at different types of spinal pain, outcomes or time points, in only 3 of the 14 analyses were the pooled treatment effects marginally above our threshold for clinical importance. NSAIDs increased the risk of gastrointestinal reactions by 2.5 times (95% CI 1.2 to 5.2), although the median duration of included trials was 7 days.

CONCLUSIONS

NSAIDs are effective for spinal pain, but the magnitude of the difference in outcomes between the intervention and placebo groups is not clinically important. At present, there are no simple analgesics that provide clinically important effects for spinal pain over placebo. There is an urgent need to develop new drug therapies for this condition.

Exercise, especially combined stretching and strengthening exercise, reduces myofascial pain: a systematic review

QUESTION

Among people with myofascial pain, does exercise reduce the intensity of the pain and disability?

DESIGN

Systematic review of randomised and quasi-randomised controlled trials.

PARTICIPANTS

People with myofascial pain of any duration.

INTERVENTION

Exercise versus minimal or no intervention and exercise versus other intervention.

OUTCOME MEASURES

Pain intensity and disability.

RESULTS

Eight studies involving 255 participants were included. Pooled estimates from six studies showed statistically significant effects of exercise when compared with minimal or no intervention (support and encouragement or no treatment) on pain intensity at short-term follow-up. The weighted mean difference in pain intensity due to exercise was -1.2 points (95% CI -2.3 to -0.1) on a 0 to 10 scale. Pooled estimates from two studies showed a non-significant effect of exercise when compared with other interventions (electrotherapy or dry needling) on pain intensity at short-term follow-up. The weighted mean difference in pain intensity due to exercise instead of other therapies was 0.4 points (95% CI -0.3 to 1.1) on a 0 to 10 scale. Individual studies reported no significant effects of exercise on disability compared with minimal intervention (-0.4, 95% CI -1.3 to 0.5) and other interventions (0.0, 95% CI -0.8 to 0.8) at short-term follow-up. Sensitivity analysis suggested that combining stretching and strengthening achieves greater short-term effects on pain intensity compared with minimal or no intervention (-2.3, 95% CI -4.1 to -0.5).

CONCLUSION

Evidence from a limited number of trials indicates that exercise has positive small-to-moderate effects on pain intensity at short-term follow-up in people with myofascial pain. A combination of stretching and strengthening exercises seems to achieve greater effects. These estimates may change with future high-quality studies. [Mata Diz JB, de Souza JRLM, Leopoldino AAO, Oliveira VC (2016) Exercise, especially combined stretching and strengthening exercise, reduces myofascial pain: a systematic review.Journal of Physiotherapy63: 17-22].

A 9-year follow-up of a self-management group intervention for persistent neck pain in primary health care: a randomized controlled trial

BACKGROUND AND OBJECTIVE

In previous short-term and 2-year follow-ups, a pain and stress self-management group intervention (PASS) had better effect on pain-related disability, self-efficacy, catastrophizing, and perceived pain control than individually administered physiotherapy (IAPT) for patients with persistent tension-type neck pain. Studies that have evaluated long-term effects of self-management approaches toward persistent neck pain are sparse. The objective of this study was to compare pain-related disability, self-efficacy for activities of daily living (ADL), catastrophizing, pain, pain control, use of analgesics, and health care utilization in people with persistent tension-type neck pain 9 years after they received the PASS or IAPT.

MATERIALS AND METHODS

Of 156 people (PASS, n = 77; IAPT, n = 79) originally included in a randomized controlled trial, 129 people (PASS, n = 63; IAPT, n = 66) were eligible and were approached for the 9-year follow-up. They were sent a self-assessment questionnaire, comprising the Neck Disability Index, the Self-Efficacy Scale, the Coping Strategies Questionnaire, and questions regarding pain, analgesics, and health care utilization. Mixed linear models for repeated measures analysis or generalized estimating equations were used to evaluate the differences between groups and within groups over time (baseline, previous follow-ups, and 9-year follow-up) and the interaction effect of "time by group".

RESULTS

Ninety-four participants (73%) responded (PASS, n = 48; IAPT, n = 46). At 9 years, PASS participants reported less pain-related disability, pain at worst, and analgesics usage, and a trend toward better self-efficacy compared to IAPT participants. There was a difference between groups in terms of change over time for disability, self-efficacy for ADL, catastrophizing, perceived pain control, and health care visits in favor of PASS. Analyses of simple main effects at 9 years showed that the PASS group had less disability (p = 0.006) and a trend toward better self-efficacy (p = 0.059) than the IAPT group.

CONCLUSION

The favorable effects on pain-related disability of PASS were sustained 9 years after the intervention.

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

BACKGROUND CONTEXT

Little is known about the effectiveness of multimodal care for individuals with whiplash-associated disorders (WAD) and neck pain and associated disorders (NAD).

PURPOSE

To update findings of the Bone and Joint Decade 2000-2010 Task Force on Neck Pain and Its Associated Disorders and evaluate the effectiveness of multimodal care for the management of patients with WAD or NAD.

STUDY DESIGN/SETTING

Systematic review and best-evidence synthesis.

PATIENT SAMPLE

We included randomized controlled trials (RCTs), cohort studies, and case-control studies.

OUTCOME MEASURES

Self-rated recovery, functional recovery (eg, disability, return to activities, work, or school), pain intensity, health-related quality of life, psychological outcomes (eg, depression, fear), or adverse events.

METHODS

We systematically searched five electronic databases (MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane Central Register of Controlled Trials) from 2000 to 2013. RCTs, cohort, and case-control studies meeting our selection criteria were eligible for critical appraisal. Random pairs of independent reviewers critically appraised eligible studies using the Scottish Intercollegiate Guidelines Network criteria. Scientifically admissible studies were summarized using evidence tables and synthesized following best-evidence synthesis principles.

RESULTS

We retrieved 2,187 articles, and 23 articles were eligible for critical appraisal. Of those, 18 articles from 14 different RCTs were scientifically admissible. There were a total of 31 treatment arms, including 27 unique multimodal programs of care. Overall, the evidence suggests that multimodal care that includes manual therapy, education, and exercise may benefit patients with grades I and II WAD and NAD. General practitioner care that includes reassurance, advice to stay active, and resumption of regular activities may be an option for the early management of WAD grades I and II. Our synthesis suggests that patients receiving high-intensity health care tend to experience poorer outcomes than those who receive fewer treatments for WAD and NAD.

CONCLUSIONS

Multimodal care can benefit patients with WAD and NAD with early or persistent symptoms. The evidence does not indicate that one multimodal care package is superior to another. Clinicians should avoid high utilization of care for patients with WAD and NAD.

Cervical zygapophysial (facet) joint pain: effectiveness of interventional management strategies

Diagnostic facet joint nerve blocks have been utilized in the diagnosis of cervical facet joint pain in patients without disk herniation or radicular pain due to a lack of reliable noninvasive diagnostic measures. Therapeutic interventions include intra-articular injections, facet joint nerve blocks and radiofrequency neurotomy. The diagnostic accuracy and effectiveness of facet joint interventions have been assessed in multiple diagnostic accuracy studies, randomized controlled trials (RCTs), and systematic reviews in managing chronic neck pain. This assessment shows there is Level II evidence based on a total of 11 controlled diagnostic accuracy studies for diagnosing cervical facet joint pain in patients without disk herniation or radicular pain utilizing controlled diagnostic blocks. Due to significant variability and internal inconsistency regarding prevalence in a heterogenous population; despite 11 studies, evidence is determined as Level II. Prevalence ranged from 36% to 67% with at least 80% pain relief as the criterion standard with a false-positive rate ranging from 27% to 63%. The evidence is Level II for the long-term effectiveness of radiofrequency neurotomy and facet joint nerve blocks in managing cervical facet joint pain. There is Level III evidence for cervical intra-articular injections.

Multimodal Physiotherapy Based on a Biobehavioral Approach as a Treatment for Chronic Tension-Type Headache: A Case Report

INTRODUCTION

Tension-type headache (TTH) is the most common primary headache affecting the general population, which is characterized by bilateral headache and mild to moderate pain. This disorder causes high levels of disability and recent scientific evidence suggests that manual therapy (MT) and therapeutic exercise are effective in reducing medication intake and decreasing the frequency and intensity of headaches in patients with TTH.

CASE PRESENTATION

A 34-year-old woman was known to have chronic TTH. Initially, the patient presented moderate headaches 5 days per week, mechanical neck pain and no positive response to analgesics. A battery of self-reports was given to the patient to assess disability (using the Spanish versions of the Headache Impact Test-6 and the neck disability index), pain (visual analogue scale) and psychosocial issues (Spanish version of the pain catastrophizing scale) involved in the headaches. All measurements were taken four times during 161 days. Eleven sessions of treatment including MT, motor control therapeutic exercise (MCTE) and therapeutic patient education (TPE) were applied.

CONCLUSIONS

This biobehavioral-based multimodal physical rehabilitation treatment combining MT, TPE and MCTE produced a substantial reduction in pain intensity, pain catastrophizing, disability and the impact of headaches on patient's life.

Clinical practice in line with evidence? A survey among primary care physiotherapists in western Sweden

RATIONALE, AIMS AND OBJECTIVES

Evidence-based practice is becoming increasingly important in primary care physiotherapy. Clinical practice needs to reflect current best evidence and be concordant with evidence-based clinical guidelines. There is limited knowledge about therapeutic interventions used in primary care physiotherapy in Sweden. The objectives were to examine preferred treatment interventions reported by publicly employed physiotherapists in primary care for three common musculoskeletal disorders (low back pain, neck pain and subacromial pain), the extent to which these interventions were supported by evidence, and associations with demographic variables.

METHODS

419 physiotherapists in primary care in western Sweden were surveyed using a validated web-based questionnaire.

RESULTS

The survey was completed by 271 respondents (65%). Median number of interventions reported was 7 (range 1-16). The most common treatment interventions across the three conditions were advice on posture (reported by 82-94%), advice to stay active (86-92%), and different types of exercise (65-92%). Most of these interventions were supported by evidence. However, interventions with insufficient evidence, such as advice on posture, TENS and aquatic exercise, were also used by 29-96%. Modalities such as laser therapy and ultrasound were sparingly used (<5%), which is in line with evidence. For neck pain, use of evidence-based interventions was associated with gender and for subacromial pain, with work experience.

CONCLUSIONS

Advice and exercise therapy were the interventions most frequently reported across the three diagnoses, illustrating an active treatment strategy. While most reported interventions are supported by evidence, interventions with unclear or no evidence of effect were also used to a high extent.

Exercises for mechanical neck disorders

BACKGROUND

Neck pain is common, disabling and costly. Exercise is one treatment approach.

OBJECTIVES

To assess the effectiveness of exercises to improve pain, disability, function, patient satisfaction, quality of life and global perceived effect in adults with neck pain.

SEARCH METHODS

We searched MEDLINE, MANTIS, ClinicalTrials.gov and three other computerized databases up to between January and May 2014 plus additional sources (reference checking, citation searching, contact with authors).

SELECTION CRITERIA

We included randomized controlled trials (RCTs) comparing single therapeutic exercise with a control for adults suffering from neck pain with or without cervicogenic headache or radiculopathy.

DATA COLLECTION AND ANALYSIS

Two review authors independently conducted trial selection, data extraction, 'Risk of bias' assessment and clinical relevance. The quality of the evidence was assessed using GRADE. Meta-analyses were performed for relative risk and standardized mean differences (SMD) with 95% confidence intervals (CIs) after judging clinical and statistical heterogeneity.

MAIN RESULTS

Twenty-seven trials (2485 analyzed /3005 randomized participants) met our inclusion criteria.For acute neck pain only, no evidence was found.For chronic neck pain, moderate quality evidence supports 1) cervico-scapulothoracic and upper extremity strength training to improve pain of a moderate to large amount immediately post treatment [pooled SMD (SMDp) -0.71 (95% CI: -1.33 to -0.10)] and at short-term follow-up; 2) scapulothoracic and upper extremity endurance training for slight beneficial effect on pain at immediate post treatment and short-term follow-up; 3) combined cervical, shoulder and scapulothoracic strengthening and stretching exercises varied from a small to large magnitude of beneficial effect on pain at immediate post treatment [SMDp -0.33 (95% CI: -0.55 to -0.10)] and up to long-term follow-up and a medium magnitude of effect improving function at both immediate post treatment and at short-term follow-up [SMDp -0.45 (95%CI: -0.72 to -0.18)]; 4) cervico-scapulothoracic strengthening/stabilization exercises to improve pain and function at intermediate term [SMDp -14.90 (95% CI:-22.40 to -7.39)]; 5) Mindfulness exercises (Qigong) minimally improved function but not global perceived effect at short term. Low evidence suggests 1) breathing exercises; 2) general fitness training; 3) stretching alone; and 4) feedback exercises combined with pattern synchronization may not change pain or function at immediate post treatment to short-term follow-up. Very low evidence suggests neuromuscular eye-neck co-ordination/proprioceptive exercises may improve pain and function at short-term follow-up.For chronic cervicogenic headache, moderate quality evidence supports static-dynamic cervico-scapulothoracic strengthening/endurance exercises including pressure biofeedback immediate post treatment and probably improves pain, function and global perceived effect at long-term follow-up. Low grade evidence supports sustained natural apophyseal glides (SNAG) exercises.For acute radiculopathy, low quality evidence suggests a small benefit for pain reduction at immediate post treatment with cervical stretch/strengthening/stabilization exercises.

AUTHORS' CONCLUSIONS

No high quality evidence was found, indicating that there is still uncertainty about the effectiveness of exercise for neck pain. Using specific strengthening exercises as a part of routine practice for chronic neck pain, cervicogenic headache and radiculopathy may be beneficial. Research showed the use of strengthening and endurance exercises for the cervico-scapulothoracic and shoulder may be beneficial in reducing pain and improving function. However, when only stretching exercises were used no beneficial effects may be expected. Future research should explore optimal dosage.

Does inter-vertebral range of motion increase after spinal manipulation? A prospective cohort study

Background

Spinal manipulation for nonspecific neck pain is thought to work in part by improving inter-vertebral range of motion (IV-RoM), but it is difficult to measure this or determine whether it is related to clinical outcomes.

Objectives

This study undertook to determine whether cervical spine flexion and extension IV-RoM increases after a course of spinal manipulation, to explore relationships between any IV-RoM increases and clinical outcomes and to compare palpation with objective measurement in the detection of hypo-mobile segments.

Method

Thirty patients with nonspecific neck pain and 30 healthy controls matched for age and gender received quantitative fluoroscopy (QF) screenings to measure flexion and extension IV-RoM (C1-C6) at baseline and 4-week follow-up between September 2012-13. Patients received up to 12 neck manipulations and completed NRS, NDI and Euroqol 5D-5L at baseline, plus PGIC and satisfaction questionnaires at follow-up. IV-RoM accuracy, repeatability and hypo-mobility cut-offs were determined. Minimal detectable changes (MDC) over 4 weeks were calculated from controls. Patients and control IV-RoMs were compared at baseline as well as changes in patients over 4 weeks. Correlations between outcomes and the number of manipulations received and the agreement (Kappa) between palpated and QF-detected of hypo-mobile segments were calculated.

Results

QF had high accuracy (worst RMS error 0.5o) and repeatability (highest SEM 1.1o, lowest ICC 0.90) for IV-RoM measurement. Hypo-mobility cut offs ranged from 0.8o to 3.5o. No outcome was significantly correlated with increased IV-RoM above MDC and there was no significant difference between the number of hypo-mobile segments in patients and controls at baseline or significant increases in IV-RoMs in patients. However, there was a modest and significant correlation between the number of manipulations received and the number of levels and directions whose IV-RoM increased beyond MDC (Rho=0.39, p=0.043). There was also no agreement between palpation and QF in identifying hypo-mobile segments (Kappa 0.04-0.06).

Conclusions

This study found no differences in cervical sagittal IV-RoM between patients with non-specific neck pain and matched controls. There was a modest dose-response relationship between the number of manipulations given and number of levels increasing IV-RoM - providing evidence that neck manipulation has a mechanical effect at segmental levels. However, patient-reported outcomes were not related to this.

Role of rehabilitation medicine and physical agents in the treatment of cancer-associated pain

PURPOSE

To provide an overview of rehabilitation medicine- and physical modality-based approaches to cancer pain management, and to highlight the fact that these approaches are generally used in conjunction and that a majority are focused on minimizing pain during periods of mobility and the performance of activities of daily living.

METHODS

We performed a nonsystematic literature review and provide a description of the current standard of care.

RESULTS

Rehabilitative and physical modalities used to manage pain can be grouped into four categories: those that modulate nociception, stabilize or unload painful structures, influence physiological processes that indirectly influence nociception, or alleviate pain arising from the overloading of muscles and connective tissues that often occurs after surgery or with sarcopenia in late-stage cancer. Most modalities have been pragmatically refined over the years, and many have an evidence base, although few have been explicitly validated in the oncologic setting. With few exceptions, they are patient controlled and free of adverse effects.

CONCLUSION

Physical modalities and rehabilitation medicine offer a range of pain management approaches that may serve as beneficial adjuncts to the conventional systemic and interventional analgesic strategies used to control cancer-related pain. These approaches may be particularly beneficial to patients with movement-associated pain and those who are ambivalent regarding pharmacoanalgesia.

Lasting effects of workplace strength training for neck/shoulder/arm pain among laboratory technicians: natural experiment with 3-year follow-up

Objectives. This study investigated long-term effects and implementation processes of workplace strength training for musculoskeletal disorders. Methods. 333 and 140 laboratory technicians from private and public sector companies, respectively, replied to a 3-year follow-up questionnaire subsequent to a 1-year randomized controlled trial (RCT) with high-intensity strength training for prevention and treatment of neck, shoulder, and arm pain. Being a natural experiment, the two participating companies implemented and modified the initial training program in different ways during the subsequent 2 years after the RCT. Results. At 3-year follow-up the pain reduction in neck, shoulder, elbow, and wrist achieved during the first year was largely maintained at both companies. However, the private sector company was rated significantly better than the public sector company in (1) training adherence, (2) training culture, that is, relatively more employees trained at the workplace and with colleagues, (3) self-reported health changes, and (4) prevention of neck and wrist pain development among initially pain-free employees. Conclusions. This natural experiment shows that strength training can be implemented successfully at different companies during working hours on a long-term basis with lasting effects on pain in neck, shoulder, and arm.

Guideline-based development and practice test of quality indicators for physiotherapy care in patients with neck pain

RATIONALE, AIMS AND OBJECTIVES

Little is currently known about the quality of physiotherapy care for patients with musculoskeletal pain. Neck pain was used as an example. The aim is to develop a set of quality indicators, including a practice test.

METHODS

A systematic method is used to develop potential process and outcome indicators. An expert and user panel is used to appraise the potential quality indicators regarding clarity, relevancy, feasibility, acceptability and improvement potential. An invitation to participate in the practice test was sent to physiotherapy practices. The resulting algorithm is used to calculate the degree to which physiotherapists met these indicators (0-100%). Differences in valid outcomes are tested for significance (Student's t-test; α = 0.05) and compared with established values for clinical relevance [minimal clinically important change (MCIC)].

RESULTS

A representative set of 40 quality indicators (28 process indicators and 12 outcome indicators) is selected from 44 initial guidelines and literature-based recommendations. The process indicators (n = 28) are classified per step of the clinical reasoning process of physiotherapy care. Of the 106 potential participants from 27 practices, 38 physiotherapists (35.8%) submitted data on 96 patients with non-specific neck pain. On average, the participating physiotherapists showed a 55.6% adherence to process indicators with a great variation in scores per step of the clinical reasoning process. The outcomes for 'pain', 'headache' and 'daily functioning' were significantly better compared with baseline, and the mean differences exceeded established values for MCICs.

CONCLUSION

Guardedly, we can conclude that a systematic approach is a valuable means to develop a preliminary set of process and outcome indicators for physiotherapy care for patients with non-specific neck pain, and a practice test should be an intrinsic part of such a systematic approach as it provides valuable information on the key attributes of the set indicators.

Psychological Care, Patient Education, Orthotics, Ergonomics and Prevention Strategies for Neck Pain: An Systematic Overview Update as Part of the ICON Project

OBJECTIVES

To conduct an overview on psychological interventions, orthoses, patient education, ergonomics, and 1⁰/2⁰ neck pain prevention for adults with acute-chronic neck pain.

SEARCH STRATEGY

Computerized databases and grey literature were searched (2006-2012).

SELECTION CRITERIA

Systematic reviews of randomized controlled trials (RCTs) on pain, function/disability, global perceived effect, quality-of-life and patient satisfaction were retrieved.

DATA COLLECTION & ANALYSIS

Two independent authors selected articles, assessed risk of bias using AMSTAR tool and extracted data. The GRADE tool was used to evaluate the body of evidence and an external panel to provide critical review.

MAIN RESULTS

We retrieved 30 reviews (5-9 AMSTAR score) reporting on 75 RCTs with the following moderate GRADE evidence. For acute whiplash associated disorder (WAD), an education video in emergency rooms (1RCT, 405participants] favoured pain reduction at long-term follow-up thus helping 1 in 23 people [Standard Mean Difference: -0.44(95%CI: -0.66 to -0.23)). Use of a soft collar (2RCTs, 1278participants) was not beneficial in the long-term. For chronic neck pain, a mind-body intervention (2RCTs, 1 meta-analysis, 191participants) improved short-term pain/function in 1 of 4 or 6 participants. In workers, 2-minutes of daily scapula-thoracic endurance training (1RCT, 127participants) over 10 weeks was beneficial in 1 of 4 participants. A number of psychosocial interventions, workplace interventions, collar use and self-management educational strategies were not beneficial.

REVIEWERS' CONCLUSIONS

Moderate evidence exists for quantifying beneficial and non-beneficial effects of a limited number of interventions for acute WAD and chronic neck pain. Larger trials with more rigorous controls need to target promising interventions.

An ICON Overview on Physical Modalities for Neck Pain and Associated Disorders

INTRODUCTION

Neck pain is common, can be disabling and is costly to society. Physical modalities are often included in neck rehabilitation programs. Interventions may include thermal, electrotherapy, ultrasound, mechanical traction, laser and acupuncture. Definitive knowledge regarding optimal modalities and dosage for neck pain management is limited.

PURPOSE

To systematically review existing literature to establish the evidence-base for recommendations on physical modalities for acute to chronic neck pain.

METHODS

A comprehensive computerized and manual search strategy from January 2000 to July 2012, systematic review methodological quality assessment using AMSTAR, qualitative assessment using a GRADE approach and recommendation presentation was included. Systematic or meta-analyses of studies evaluating physical modalities were eligible. Independent assessment by at least two review team members was conducted. Data extraction was performed by one reviewer and checked by a second. Disagreements were resolved by consensus.

RESULTS

Of 103 reviews eligible, 20 were included and 83 were excluded. Short term pain relief - Moderate evidence of benefit: acupuncture, intermittent traction and laser were shown to be better than placebo for chronic neck pain. Moderate evidence of no benefit: pulsed ultrasound, infrared light or continuous traction was no better than placebo for acute whiplash associated disorder, chronic myofascial neck pain or subacute to chronic neck pain. There was no added benefit when hot packs were combined with mobilization, manipulation or electrical muscle stimulation for chronic neck pain, function or patient satisfaction at six month follow-up.

CONCLUSIONS

The current state of the evidence favours acupuncture, laser and intermittent traction for chronic neck pain. Some electrotherapies show little benefit for chronic neck pain. Consistent dosage, improved design and long term follow-up continue to be the recommendations for future research.

Pharmacological Interventions Including Medical Injections for Neck Pain: An Overview as Part of the ICON Project

OBJECTIVES

To conduct an overview (review-of-reviews) on pharmacological interventions for neck pain.

SEARCH STRATEGY

Computerized databases and grey literature were searched from 2006 to 2012.

SELECTION CRITERIA

Systematic reviews of randomized controlled trials (RCT) in adults with acute to chronic neck pain reporting effects of pharmacological interventions including injections on pain, function/disability, global perceived effect, quality of life and patient satisfaction.

DATA COLLECTION & ANALYSIS

Two independent authors selected articles, assessed risk of bias and extracted data The GRADE tool was used to evaluate the body of evidence and an external panel provided critical review.

MAIN RESULTS

We found 26 reviews reporting on 47 RCTs. Most pharmacological interventions had low to very low quality methodologic evidence with three exceptions. For chronic neck pain, there was evidence of: a small immediate benefit for eperison hydrochloride (moderate GRADE, 1 trial, 157 participants);no short-term pain relieving benefit for botulinum toxin-A compared to saline (strong GRADE; 5 trial meta-analysis, 258 participants) nor for subacute/chronic whiplash (moderate GRADE; 4 trial meta-analysis, 183 participants) including reduced pain, disability or global perceived effect; andno long-term benefit for medial branch block of facet joints with steroids (moderate GRADE; 1 trial, 120 participants) over placebo to reduce pain or disability;

REVIEWERS' CONCLUSIONS

While in general there is a lack of evidence for most pharmacological interventions, current evidence is against botulinum toxin-A for chronic neck pain or subacute/chronic whiplash; against medial branch block with steroids for chronic facet joint pain; but in favour of the muscle relaxant eperison hydrochloride for chronic neck pain.

Low Level Laser Therapy (LLLT) for Neck Pain: A Systematic Review and Meta-Regression

PURPOSE

This systematic review update evaluated low level laser therapy (LLLT) for adults with neck pain.

METHODS

Computerized searches (root up to Feb 2012) included pain, function/disability, quality of life (QoL) and global perceived effect (GPE). GRADE, effect-sizes, heterogeneity and meta-regression were assessed.

RESULTS

Of 17 trials, 10 demonstrated high risk of bias. For chronic neck pain, there was moderate quality evidence (2 trials, 109 participants) supporting LLLT over placebo to improve pain/disability/QoL/GPE up to intermediate-term (IT). For acute radiculopathy, cervical osteoarthritis or acute neck pain, low quality evidence suggested LLLT improves ST pain/function/QoL over a placebo. For chronic myofascial neck pain (5 trials, 188 participants), evidence was conflicting; a meta-regression of heterogeneous trials suggests super-pulsed LLLT increases the chance of a successful pain outcome.

CONCLUSIONS

We found diverse evidence using LLLT for neck pain. LLLT may be beneficial for chronic neck pain/function/QoL. Larger long-term dosage trials are needed.

Electrotherapy for neck pain

BACKGROUND

Neck pain is common, disabling and costly. The effectiveness of electrotherapy as a physiotherapeutic option remains unclear. This is an update of a Cochrane review first published in 2005 and previously updated in 2009.

OBJECTIVES

This systematic review assessed the short, intermediate and long-term effects of electrotherapy on pain, function, disability, patient satisfaction, global perceived effect, and quality of life in adults with neck pain with and without radiculopathy or cervicogenic headache.

SEARCH METHODS

We searched CENTRAL, MEDLINE, EMBASE, MANTIS, CINAHL, and ICL, without language restrictions, from their beginning to August 2012; handsearched relevant conference proceedings; and consulted content experts.

SELECTION CRITERIA

Randomized controlled trials (RCTs), in any language, investigating the effects of electrotherapy used primarily as unimodal treatment for neck pain. Quasi-RCTs and controlled clinical trials were excluded.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by The Cochrane Collaboration. We were unable to statistically pool any of the results, but we assessed the quality of the evidence using an adapted GRADE approach.

MAIN RESULTS

Twenty small trials (1239 people with neck pain) containing 38 comparisons were included. Analysis was limited by trials of varied quality, heterogeneous treatment subtypes and conflicting results. The main findings for reduction of neck pain by treatment with electrotherapeutic modalities were as follows.Very low quality evidence determined that pulsed electromagnetic field therapy (PEMF) and repetitive magnetic stimulation (rMS) were more effective than placebo, while transcutaneous electrical nerve stimulation (TENS) showed inconsistent results.Very low quality evidence determined that PEMF, rMS and TENS were more effective than placebo.Low quality evidence (1 trial, 52 participants) determined that permanent magnets (necklace) were no more effective than placebo (standardized mean difference (SMD) 0.27, 95% CI -0.27 to 0.82, random-effects model).Very low quality evidence showed that modulated galvanic current, iontophoresis and electric muscle stimulation (EMS) were not more effective than placebo.There were four trials that reported on other outcomes such as function and global perceived effects, but none of the effects were of clinical importance. When TENS, iontophoresis and PEMF were compared to another treatment, very low quality evidence prevented us from suggesting any recommendations. No adverse side effects were reported in any of the included studies.

AUTHORS' CONCLUSIONS

We cannot make any definite statements on the efficacy and clinical usefulness of electrotherapy modalities for neck pain. Since the evidence is of low or very low quality, we are uncertain about the estimate of the effect. Further research is very likely to change both the estimate of effect and our confidence in the results. Current evidence for PEMF, rMS, and TENS shows that these modalities might be more effective than placebo. When compared to other interventions the quality of evidence was very low thus preventing further recommendations.Funding bias should be considered, especially in PEMF studies. Galvanic current, iontophoresis, EMS, and a static magnetic field did not reduce pain or disability. Future trials on these interventions should have larger patient samples, include more precise standardization, and detail treatment characteristics.

Effect of therapeutic exercise on pain and disability in the management of chronic nonspecific neck pain: systematic review and meta-analysis of randomized trials

BACKGROUND

Given the prevalence of chronic nonspecific neck pain (CNSNP) internationally, attention has increasingly been paid in recent years to evaluating the efficacy of therapeutic exercise (TE) in the management of this condition.

PURPOSE

The purpose of this study was to conduct a current review of randomized controlled trials concerning the effect of TE on pain and disability among people with CNSNP, perform a meta-analysis, and summarize current understanding.

DATA SOURCES

Data were obtained from MEDLINE, Cumulative Index to Nursing and Allied Health Literature (CINAHL), EMBASE, Physiotherapy Evidence Database (PEDro), and Cochrane Central Register of Controlled Trials (CENTRAL) databases from their inception to August 2012. Reference lists of relevant literature reviews also were tracked.

STUDY SELECTION

All published randomized trials without any restriction regarding time of publication or language were considered for inclusion. Study participants had to be symptomatic adults with only CNSNP.

DATA EXTRACTION

Two reviewers independently selected the studies, conducted the quality assessment, and extracted the results. Data were pooled in a meta-analysis using a random-effects model.

DATA SYNTHESIS

Seven studies met the inclusion criteria. Therapeutic exercise proved to have medium and significant short-term and intermediate-term effects on pain (g=-0.53, 95% confidence interval [CI]=-0.86 to -0.20, and g=-0.45, 95% CI=-0.82 to -0.07, respectively) and medium but not significant short-term and intermediate-term effects on disability (g=-0.39, 95% CI=-0.86 to 0.07, and g=-0.46, 95% CI=-1.00 to -0.08, respectively).

LIMITATIONS

Only one study investigated the effect of TE on pain and disability at follow-up longer than 6 months after intervention.

CONCLUSIONS

Consistent with other reviews, the results support the use of TE in the management of CNSNP. In particular, a significant overall effect size was found supporting TE for its effect on pain in both the short and intermediate terms.

Proprioception interventions to improve cervical position sense in cervical pathology

Background:

Non-specific cervical pain is a common pathology and is difficult to treat. Various types of treatment interventions have been used individually or in combination. Proprioception training has been suggested as an aspect of intervention for cervical pathology but no systematic review has been conducted to evaluate the effectiveness of cervical proprioception retraining on reposition sense.

Methods:

A systematic review of the literature was performed to evaluate the effectiveness of proprioception interventions to improve cervical position sense (PS) in patients with pathology. A modified American Academy of Cerebral Palsy and Developmental Medicine method was used to systematically grade the level of evidence. In addition, a meta-analysis was performed on the intervention effects on PS or pain.

Findings:

PS was measured in 11 studies; seven used a laser pointer while four used motion detection instrumentation. Various treatment interventions, including deep cervical flexor activation, eye-head neck coordination exercises, mobilisation, manipulation and a multi-behavioural exercise approach were used individually or in combination to affect proprioception. Pain was measured in six studies using various outcome measures. The meta-analyses showed high heterogeneity of results in favour of treatment interventions for flexion/extension and for right/left rotation to improve PS as well as for pain reduction for the pain outcome measures.

Conclusions:

All the treatment interventions activated proprioceptors through muscle activation and joint or skin sensory receptors. The use of eye-head-neck coordination exercises produced moderate and large treatment effects for improving PS. This type of exercise links the sensory/motor (proprioception) systems of the neck with the oculomotor and vestibular systems to improve PS. Pain was also reduced (moderate effect size) with the use of these techniques. Clinicians targeting improvements in cervical PS may use this evidence, but further research is needed.

People seeking treatment for a new episode of neck pain typically have rapid improvement in symptoms: an observational study

QUESTION

What is the clinical course of a new episode of non-specific neck pain in people who are treated with multimodal physical therapies in a primary care setting?

DESIGN

Observational study with 3-month follow-up, run in conjunction with a randomised trial.

PARTICIPANTS

181 adults who consulted a physiotherapist or chiropractor for a new episode of nonspecific neck pain.

OUTCOME MEASURES

Time to recover from the episode of neck pain, time to recover normal activity, and pain and neck-related disability at three months. Clinical and demographic characteristics were investigated as potential predictors of recovery.

RESULTS

Within 3 months, 53% of participants reported complete recovery from the episode of neck pain. On a scale from 0 (none) to 10 (worst), pain improved from 6.1 (SD 2.0) at baseline to 2.5 (SD 2.1) at 2 weeks and to 1.5 (SD 1.8) at 3 months. On a scale from 0 (none) to 50 (worst), disability improved from 15.5 (SD 7.4) at baseline to 5.4 (SD 6.4) at 3 months. Faster recovery was independently associated with better self-rated general health, shorter duration of symptoms, being a smoker, and absence of concomitant upper back pain or headache. Higher disability at 3 months was independently associated with higher disability at baseline, concomitant upper or lower back pain, older age, and previous sick leave for neck pain.

CONCLUSION

People who seek physical treatments for a new episode of neck pain in this primary care setting typically have high pain scores that improve rapidly after commencing treatment. Although almost half of those who seek treatment do not recover completely within three months, residual pain and disability in this group is relatively low. Physiotherapists should reassure people with a new episode of neck pain that rapid improvement in symptoms is common, modifying this advice where applicable based on risk factors.

Exercise therapy for bone and muscle health: an overview of systematic reviews

BACKGROUND

Musculoskeletal conditions (MSCs) are widely prevalent in present-day society, with resultant high healthcare costs and substantial negative effects on patient health and quality of life. The main aim of this overview was to synthesize evidence from systematic reviews on the effects of exercise therapy (ET) on pain and physical function for patients with MSCs. In addition, the evidence for the effect of ET on disease pathogenesis, and whether particular components of exercise programs are associated with the size of the treatment effects, was also explored.

METHODS

We included four common conditions: fibromyalgia (FM), low back pain (LBP), neck pain (NP), and shoulder pain (SP), and four specific musculoskeletal diseases: osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis (AS), and osteoporosis (OP). We first included Cochrane reviews with the most recent update being January 2007 or later, and then searched for non-Cochrane reviews published after this date. Pain and physical functioning were selected as primary outcomes.

RESULTS

We identified 9 reviews, comprising a total of 224 trials and 24,059 patients. In addition, one review addressing the effect of exercise on pathogenesis was included. Overall, we found solid evidence supporting ET in the management of MSCs, but there were substantial differences in the level of research evidence between the included diagnostic groups. The standardized mean differences for knee OA, LBP, FM, and SP varied between 0.30 and 0.65 and were significantly in favor of exercise for both pain and function. For NP, hip OA, RA, and AS, the effect estimates were generally smaller and not always significant. There was little or no evidence that ET can influence disease pathogenesis. The only exception was for osteoporosis, where there was evidence that ET increases bone mineral density in postmenopausal women, but no significant effects were found for clinically relevant outcomes (fractures). For LBP and knee OA, there was evidence suggesting that the treatment effect increases with the number of exercise sessions.

CONCLUSIONS

There is empirical evidence that ET has beneficial clinical effects for most MSCs. Except for osteoporosis, there seems to be a gap in the understanding of the ways in which ET influences disease mechanisms.
