Some conservative interventions are more effective than others for people with chronic non-specific neck pain: a systematic review and network meta-analysis

The effect of combining physiotherapy with dry needling in patients with cervical spondylosis: A randomized controlled trial

BACKGROUND

There are no data on the additional contribution of dry needling (DN) for trigger points (TPs) accompanying patients with cervical spondylosis (CS).

OBJECTIVE

To analyse the contribution of DN applied to concomitant active TPs in the upper trapezius muscle on the treatment outcomes of physiotherapy in CS.

METHODS

In this prospective randomized controlled study, 70 patients with CS and active TPs in the upper trapezius muscle were included. The first group received physiotherapy for 5 days per week for 3 weeks. The second group received DN with the same program. All participants were evaluated before treatment (day 0) and at the end of treatment (day 21) in terms of pain, functional status, quality of life, anxiety/depression scores, and number of TPs.

RESULTS

33 patients in the first group and 32 patients in the second group completed the study. While the change over time was found significant in all variables, the change was not different between groups. The group-time interaction effect was not found to be statistically significant in any variable. Percentage changes of all variables were similar between the groups.

CONCLUSION

DN treatment added to the physiotherapy did not contribute to recovery in patients with CS.

Effectiveness and safety of manual therapy when compared with oral pain medications in patients with neck pain: a systematic review and meta-analysis

BACKGROUND

This systematic review and meta-analysis seeks to investigate the effectiveness and safety of manual therapy (MT) interventions compared to oral pain medication in the management of neck pain.

METHODS

We searched from inception to March 2023, in Cochrane Central Register of Controller Trials (CENTRAL), MEDLINE, EMBASE, Allied and Complementary Medicine (AMED) and Cumulative Index to Nursing and Allied Health Literature (CINAHL; EBSCO) for randomized controlled trials that examined the effect of manual therapy interventions for neck pain when compared to medication in adults with self-reported neck pain, irrespective of radicular findings, specific cause, and associated cervicogenic headaches. We used the Cochrane Risk of Bias 2 tool to assess the potential risk of bias in the included studies, and the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach to grade the quality of the evidence.

RESULTS

Nine trials (779 participants) were included in the meta-analysis. We found low certainty of evidence that MT interventions may be more effective than oral pain medication in pain reduction in the short-term (Standardized Mean Difference: -0.39; 95% CI -0.66 to -0.11; 8 trials, 676 participants), and moderate certainty of evidence that MT interventions may be more effective than oral pain medication in pain reduction in the long-term (Standardized Mean Difference: - 0.36; 95% CI - 0.55 to - 0.17; 6 trials, 567 participants). We found low certainty evidence that the risk of adverse events may be lower for patients that received MT compared to the ones that received oral pain medication (Risk Ratio: 0.59; 95% CI 0.43 to 0.79; 5 trials, 426 participants).

CONCLUSIONS

MT may be more effective for people with neck pain in both short and long-term with a better safety profile regarding adverse events when compared to patients receiving oral pain medications. However, we advise caution when interpreting our safety results due to the different level of reporting strategies in place for MT and medication-induced adverse events. Future MT trials should create and adhere to strict reporting strategies with regards to adverse events to help gain a better understanding on the nature of potential MT-induced adverse events and to ensure patient safety.

The reliability and validity of a novel wearable inertial sensor to measure the cervical proprioception

BACKGROUND

Proprioceptive function assessment is crucial in clinical practice for patients with chronic non-specific neck pain (CNNP) as it is a major issue affecting their condition.

PURPOSE

To verify the reliability and validity of baiobit sensor in measuring the neck proprioceptive function of CNNP patients.

METHODS

Fifty-three CNNP patients were recruited (36 females, 17 males; age range 21-60 years) and were assessed for cervical joint position error by two blinded raters using the Baiobit sensor and laser pointer devices. The second measurement was conducted by the same rater 48 h later. Intra and inter-rater reliability of the Baiobit sensor was evaluated using the intra-class correlation coefficient (ICC), while the validity of the Baiobit sensor was established using the Spearman correlation coefficient.

RESULTS

The Baiobit sensor demonstrated moderate to excellent intra-rater reliability in flexion, extension, left lateral flexion, right lateral flexion, and right rotation (ICCs=0.71∼0.85, 95 %CIs: 0.50∼0.91), left-rotation shows poor to good intra-rater reliability (ICC=0.56, 95 %CI: 0.25∼0.75). The Baiobit sensor also demonstrated moderate to excellent inter-rater reliability in flexion, extension, left lateral flexion, right lateral flexion, and right rotation (ICCs=0.80∼0.88, 95 %CIs: 0.65∼0.91), left-rotation shows poor to good intra-rater reliability (ICC=0.59, 95 %CI: 0.29∼0.76). Validity analysis showed that the Baiobit sensor had a range of low to high validity (r = 0.46∼0.88) for measuring cervical proprioception function, with lower validity observed in the left flexion direction. The Baiobit showed good absolute reliability with low SEM and MDC90 values (0.35°∼2.42°).

CONCLUSION

The new device could be used as an alternative tool to evaluate neck proprioception.

Specific and shared mechanisms associated with treatment for chronic neck pain: study protocol for the SS-MECH trial

BACKGROUND

Treatment mechanisms involve the steps or processes through which an intervention unfolds and produces change in an outcome variable. Treatment mechanisms can be specific to the intervention provided (i.e. pain modulation) or shared with other treatments (i.e. reduced fear of movement). Whether specific and shared treatment mechanisms are different across interventions and whether they lead to the outcomes seen in trials is largely unknown. The management of individuals with chronic neck pain routinely include manual therapy (MT) and resistance exercise (RE), as both approaches are included in clinical practice guidelines and both yield similar outcomes.

OBJECTIVES

Our study plans to answer two research questions: 1) what are the specific mechanisms associated with MT versus interventions (and are these different), and 2) what are the shared mechanisms associated with these interventions, and do specific or shared mechanisms mediate clinical outcomes?

METHODS

This study will involve a 2-group parallel (1:1) single-blinded randomized trial to compare the specific and potential shared treatment mechanisms between these two approaches. We will enroll individuals with a history of chronic neck pain and evaluate whether specific or shared mechanisms mediate clinical outcomes.

RESULTS

We hypothesize that MT and RE approaches will both exhibit different specific treatment mechanisms, and that both approaches will exhibit shared treatment mechanisms, which will notably influence outcomes at both discharge and 6-months.

CONCLUSIONS

This study is important because it will help identify what specific or shared treatment mechanisms are associated with different interventions and, how different treatment mechanisms influence clinical outcomes.

Comparative effectiveness of non-pharmacological interventions on sleep in individuals with chronic musculoskeletal pain: A systematic review with network meta-analysis

This network meta-analysis aimed to estimate the comparative effectiveness of non-pharmacological interventions on sleep in individuals with chronic musculoskeletal pain. Seven databases were systematically searched up to February 2023. A random-effects network meta-analysis in a frequentist framework was performed to synthesize continuous data as standardized mean differences (SMD) along with a 95% confidence interval (95% CI). A total of 15,641 records were identified, and 107 randomized controlled trials involving 8,121 participants were included. Of 14 identified interventions, eight were significantly more effective than passive control in improving sleep quality at immediate post-intervention (SMDs = 0.67-0.74), with cognitive behavioral therapy (CBT) being the most effective treatment (SMD = 0.74, 95% CI: 0.45-1.03). Only CBT demonstrated sustained effects at short-term (SMD = 1.56; 95% CI: 0.62-2.49) and mid-term (SMD = 1.23; 95% CI: 0.44-2.03) follow-ups. Furthermore, CBT significantly improved subjective (SMD = 0.64; 95% CI: 0.25-1.03) and objective (SMD = 0.30; 95% CI: 0.01-0.59) sleep efficiency compared with passive control at immediate post-intervention. Our findings support CBT as the first-line treatment for improving sleep in individuals with chronic musculoskeletal pain, given its superior effectiveness across multiple sleep outcomes and its sustainable effects until mid-term follow-up. However, the certainty of evidence for these interventions in improving sleep quality was very low to low.

Specific Neurodynamic Exercises on Pain and Disability in Old Women with Chronic Mechanical Neck Pain: A Randomized Controlled Trial

Neurodynamic exercise is a specific type of exercise used as a neural treatment that focuses on restoring altered homeostasis in the neuroimmune system by mobilising the nervous system and other structures. A prospective, randomized clinical trial was performed to evaluate the effect of neurodynamic exercises on disability and neck pain in elderly women over four weeks. Participants were randomized into two groups: a neurodynamic (NM) group (n = 28) and a non-specific exercise (NSE) group (n = 28). Inclusion criteria were women over 65 years of age who subjectively admitted to having mechanical neck pain for more than six months. Results showed that specific neurodynamic exercises can improve pain and disability in older women with chronic mechanical neck pain. Improvements were observed in all variables (p < 0.05). Significant between-group differences in favour of the NM group were only found for neck pressure pain thresholds and both tibialis anterior muscles. Larger effect sizes were obtained in favour of the NM group, especially for pain, disability, neck extension and inclination and pressure pain thresholds. Neurodynamic exercises have been shown to be more clinically relevant in disability and neck pain in older women.

A single session of action observation therapy versus observing a natural landscape in adults with chronic neck pain - a randomized controlled trial

BACKGROUND

Action observation (AO) has emerged as a potential neurorehabilitation therapy for patients with neck pain (NP), but evidence of its effectiveness is scarce. This study aims to assess the effect of a single session of AO when compared to observing a natural landscape on NP intensity, fear of movement, fear-avoidance beliefs, neck muscles' strength, pressure pain threshold, and tactile acuity.

METHODS

Sixty participants with NP were randomly allocated to the AO group (n = 30) or control group (n = 30). Both groups watched an 11-minute video: the AO group watched a video of a person matched for age and sex performing neck exercises, while the control group watched a video of natural landscapes. Neck pain intensity, fear of movement, fear-avoidance beliefs, tactile acuity, pressure pain thresholds, and neck muscle strength were assessed both at baseline and post-intervention. General linear models of repeated measures (ANCOVA of two factors) were used to explore between-group differences at post-intervention.

RESULTS

There was a significant main effect of time for pain intensity (p = 0.02; η2p = 0.09; within-group mean change and 95% CI: AO=-1.44 (-2.28, -0.59); control=-1.90 (-2.74, -1.06), but no time versus group interaction (p = 0.46). A time versus group significant interaction was found for one out of the six measurement sites of two-point discrimination and the neck flexors strength (p < 0.05) favoring the control group. No other statistically significant differences were found for the remaining variables).

CONCLUSIONS

Results suggest a similar acute benefit for both a single session of AO and observing natural landscapes for promoting hypoalgesia, but no impact on kinesiophobia, fear-avoidance beliefs, or pressure pain thresholds. Also, AO had no positive effect on two-point discrimination and muscle strength. Further research is needed, with longer interventions.

Effectiveness of Self-Care Education for Chronic Neck Pain: A Systematic Review and Meta-Analysis

Self-care programs for chronic neck pain are relevant to everyday life and can lead to long- term improvement. More studies on their effectiveness, key components and appropriate duration are needed. The aim of this study was to determine the effectiveness of self-care programs for patients with chronic neck pain. A systematic review and meta-analysis of randomized controlled trials was conducted according to the PRISMA guidelines. After searching in PubMed, Web of Science, Scopus and ScienceDirect, eleven studies met the inclusion criteria. Self-care education interventions typically consisted of education (i.e., pain neuro-science education or general educational concepts) accompanied by exercise or manual therapy. The most frequent components were addressing physical and psychological symptoms and engaging in self-care strategies. The least frequent ones were monitoring and recording symptoms and discussing with providers of medical care. The duration of the interventions ranged from three sessions to six months. Finally, individual and supervised modalities were the most frequent. After pooling the data, a meta-analysis was carried out according to four variables (i.e., pain, disability, kinesiophobia and catastrophization) and showed significant results (p < 0.05) in favor of self-care interventions. This systematic review and meta-analysis suggests that self-education interventions improve pain, psychological pain-related variables and disability in patients with chronic neck pain. The most frequently used components were addressing physical and psychological symptoms and engaging in self-care strategies. Future trials should focus on including other components, such as discussing symptoms with providers of medical care or self-monitoring symptoms. Additional areas of focus include more homogeneous doses and comparator treatments, as well as studies with better evidence to reach more solid conclusions.

Benefits and Harms of Spinal Manipulative Therapy for Treating Recent and Persistent Nonspecific Neck Pain: A Systematic Review With Meta-analysis

OBJECTIVE: We aimed to estimate the benefits and harms of cervical spinal manipulative therapy (SMT) for treating neck pain. DESIGN: Intervention systematic review with meta-analysis of randomized controlled trials (RCTs). LITERATURE SEARCH: We searched the MEDLINE, Cochrane CENTRAL, Embase, CINAHL, PEDro, Chiropractic Literature Index bibliographic databases, and grey literature sources, up to June 6, 2022. STUDY SELECTION CRITERIA: RCTs evaluating SMT compared to guideline-recommended and nonrecommended interventions, sham SMT, and no intervention for adults with neck pain were eligible for our systematic review. Prespecified outcomes included pain, range of motion, disability, health-related quality of life. DATA SYNTHESIS: Random-effects meta-analysis for clinically homogenous RCTs at short-term and long-term outcomes. Risk of bias was assessed using the Cochrane Risk of Bias 2.0 Tool. We used the Grading of Recommendations, Assessment, Development, and Evaluations approach to judge the certainty of evidence. RESULTS: We included 28 RCTs. There was very low to low certainty evidence that SMT was more effective than recommended interventions for improving pain at short term (standardized mean difference [SMD], 0.66; 95% confidence interval [CI]: 0.35, 0.97) and long term (SMD, 0.73; 95% CI: 0.31, 1.16), and for reducing disability at short-term (SMD, 0.95; 95% CI: 0.48, 1.42) and long term (SMD, 0.65; 95% CI: 0.23, 1.06). Transient side effects only were found (eg, muscle soreness). CONCLUSION: There was very low certainty evidence supporting cervical SMT as an intervention to reduce pain and improve disability in people with neck pain.

Efficacy and safety of acupuncture for pregnancy-related low back pain: A systematic review and meta-analysis

Background

Pregnancy-related low back pain (PLBP) is a common musculoskeletal disorder, affecting people's physical and psychological health. Acupuncture is widely used in clinical practice as a treatment for PLBP. This study aimed to evaluate the efficacy and safety of acupuncture or acupuncture combined with other treatments for PLBP patients.

Methods

The Cochrane Library, PubMed, EMBASE, Web of Science, the Chinese Biological Medicine Database, China National Knowledge Infrastructure, WanFang Database, and VIP information database were searched from inception to January 31, 2022. Randomized controlled trials (RCTs) were eligible, without blinding and language restriction. Cochrane's risk of bias tool was used to assess the methodological quality. Meta-analysis was performed using RevMan 5.3.

Results

Twelve randomized controlled trials involving 1302 patients were included. The results showed that compared to the control group, the VAS score was significantly decreased after acupuncture treatment. In addition, no significant difference was found in the preterm delivery rate (RR = 0.38, 95%CI: 0.24 to 0.61, P = 0.97) after acupuncture treatment. Compared with other therapies, acupuncture or acupuncture plus other therapies revealed a significant increase in the effective rate (OR: 6.92, 95%CI: 2.44 to 19.67, I2 = 0%). No serious adverse events owing to acupuncture were reported.

Conclusion

Acupuncture or acupuncture combined with other interventions was a safe and effective therapy for treating PLBP. However, the methodological quality of the RCTs was low. More rigorous and well-designed trials should be conducted.

[Complementary and alternative medicine-An option for chronic pain patients?]

The interest of patients with chronic pain in complementary and alternative medicine (CAM) is high. The aim of an accompanying complementary therapy is to strengthen the patient's self-efficacy, the ability to make decisions and the autonomy. The best evidence exists for physical activity and a balanced diet. Exercise combinations of strength and endurance as well as targeted strengthening of the muscles in the area of the pain are particularly suitable. When choosing the form of exercise, low-threshold training options are recommended. There is no reliable evidence for kinesio taping, homeopathy, neural therapy and draining procedures. The extensive data on acupuncture must be interpreted taking methodological limitations into account. Heat applications can support multimodal pain therapy. In the case of anti-inflammatory phytotherapeutic agents, there are good rationales from basic research and reliable empirical knowledge regarding the dosage. The evidence on cannabis is low.
