Effects of matched vs. unmatched physical therapy interventions on pain or disability in patients with neck pain - a systematic review and meta-analysis

BACKGROUND

The interventions performed in most randomized controlled trials (RCTs) on neck pain patients are standardized, irrespective of the high heterogeneity of patients. However, clinicians tend to choose an intervention based on the patients' clinical characteristics, and thus match the treatment to the patient.

OBJECTIVES

To investigate the effectiveness of interventions matched to the clinical characteristics of patients with neck pain versus the same, but unmatched treatment for improving pain or disability.

DESIGN

A systematic review and meta-analysis conducted following Cochrane guidelines.

METHODS

Databases searches were performed from inception to September 2023. RCTs were included if the patients in the experimental group received a treatment matched to clinical presentation or to clinicians' assessment, if the patients in the control group received a similar but unmatched treatment, and if pain or disability were reported as outcome measures.

RESULTS

The literature search produced 9516 records of which 27 met the inclusion criteria. Matched exercise therapy was superior to unmatched exercise for pain (SMD -0.57; 95% CI -0.95, -0.18) and for disability (SMD -0.69; 95% CI -1.14, -0.23) at short term, but not at intermediate-term follow-up. Matched manual treatment was not superior to unmatched manual therapy for pain or for disability at short or intermediate-term follow-up.

CONCLUSIONS

Results suggest that matching exercise to movement limitation, trapezius myalgia, or forward head position may lead to better outcomes in the short term, but not in the intermediate-term. Matched manual therapy was not superior to unmatched treatment either short or intermediate-term. Further research is warranted to verify if those criteria are potentially useful matching criteria.

Periosteal Needling to the Cervical Articular Pillars as an Adjunct Intervention for Treatment of Chronic Neck Pain and Headache: A Case Report

(1) Background: Periosteal dry needling (PDN) involves clinicians using a solid filiform needle to stimulate bone for analgesic purposes. This case report presents the use of PDN to the cervical articular pillars (CAPs) in an 85-year-old female with chronic neck pain and headache. (2) Case description: PDN was applied to the right C2–C3 articular pillars, following trigger point dry needling (TrPDN) and manual therapy, in order to provide a direct sensory stimulus to the corresponding sclerotomes. PDN added over two treatments led to improved cervical range of motion and eliminated the patient’s neck pain and headache at 1 week follow-up. (3) Outcomes: At discharge, clinically relevant improvements were demonstrated on the numeric pain rating scale (NPRS), which improved from an 8/10 on intake to a 0/10 at rest and with all movements. In addition, the patient exceeded the risk adjusted predicted four-point score improvement and the minimal clinically important improvement (MCII) value of four points on the Focus on Therapeutic Outcomes (FOTO) Neck Functional Status (Neck FS). At one month post-discharge, the patient remained symptom-free. (4) Discussion: In the context of an evidence-informed approach for neck pain and headache, PDN led to marked improvements in pain and function. Patient outcomes exceeded predictive analytic expectations for functional gains and efficient utilization of visits and time in days. Combined with other interventions, PDN to the CAPs could be a viable technique to treat chronic neck pain with headache.

Dry needling in active or latent trigger point in patients with neck pain: a randomized clinical trial

The purpose was to determine the efficacy of deep dry needling (DDN) applied on an active myofascial trigger point (MTrP) versus a latent-MTrP versus a non-MTrP location, on pain reduction and cervical disability, in patients with chronic neck pain. A randomized, double-blind clinical trial design was used. A sample of 65 patients was divided into non-MTrP-DDN, active-MTrP-DDN and latent-MTrP-DDN groups. The visual analog scale (VAS), reproduction of the patient's pain, number of local twitch responses, pressure pain threshold (PPT) and Neck Disability Index (NDI) were assessed before, during and after the intervention and up to 1 month post-intervention. The active-MTrP-DDN-group reduced pain intensity more than non-MTrP-DDN-group after a week and a month (P < 0.01), as well as showing the greatest improvement in tibialis muscle PPT. The treatment of both Active and Latent MTrPs was associated with the reproduction of the patient's pain. The application of DDN on an active-MTrP in the upper trapezius muscle shows greater improvements in pain intensity after 1 week and 1 month post-intervention, compared to DDN applied in latent-MTrPs or outside of MTrPs in patients with neck pain.

Elasticity of neck muscles in cervicogenic headache

AIM

To compare the elasticity of the sternocleidomastoid and trapezius muscles in patients with cervicogenic headache and in healthy volunteers.

METHODS

The medical history of 23 patients with cervicogenic headache was taken with a focus on pain characteristics. Elasticity of the sternocleidomastoid and trapezius muscles was measured by using shear wave elastography. Results were then compared with 23 healthy volunteers.

RESULTS

The sternocleidomastoid muscle was significantly stiffer in patients with cervicogenic headache compared to healthy volunteers. The stiffness increased gradually from the parasternal area, where it was negligible, to the area near the mastoid process where it reached over 20 kPa. There was no difference in the stiffness of the trapezius muscle. The stiffness of the sternocleidomastoid muscle does show a significant dependence on headache characteristics (e.g., laterality, severity, or frequency).

CONCLUSION

The results of this pilot study show that patients with cervicogenic headache have a higher stiffness of the sternocleidomastoid muscle than healthy volunteers. These findings suggest that elastography could be used as a diagnostic tool in cervicogenic headache.

Is Dry Needling Applied by Physical Therapists Effective for Pain in Musculoskeletal Conditions? A Systematic Review and Meta-Analysis

OBJECTIVE

The main objective of this systematic review and meta-analysis was to determine the short-, medium-, and long-term effectiveness of dry needling (DN) applied by physical therapists to myofascial trigger points for the treatment of pain.

METHODS

PubMed, Scopus, SportDiscus, and Web of Science databases were searched from their inception to February 2020. Randomized controlled trials that compared DN with other treatments or placebo and measured pain with a visual analog Scale or another numerical pain rating scale were included. Two authors used a personalized form to collect the following data relevant to the objectives of the review from each article independently: study design, purpose, sample size, diagnosis, characteristics of DN intervention, characteristics of placebo intervention, outcome measures, period of assessment, body region, DN technique, and number of sessions. The initial search identified 1771 articles. After the selection, 102 articles were assessed for eligibility; 42 of these articles measuring pain were used for the meta-analysis. Four meta-analyses were performed according to the follow-up period from the last reported treatment.

RESULTS

This meta-analysis found a large effect to decrease pain within 72 hours (standardized mean difference [SMD] = -0.81; 95% CI = -1.21 to -0.40), a moderate effect in 1 to 3 weeks (SMD = -0.69; 95% CI = -1.02 to -0.35), a large effect in 4 to 12 weeks (SMD = -0.85; 95% CI = -1.30 to -0.40), and a large effect in 13 to 24 weeks (SMD = -0.81; 95% CI = -1.64 to -0.03). The risk of bias was generally low; however, the heterogeneity of the results downgraded the level of evidence.

CONCLUSIONS

Low-quality evidence that the immediate to 72-hour (large) effect, 4- to 12-week (large) effect, 13- to 24-week (large) effect, and moderate-quality 1- to 3-week (moderate) effect suggested that DN performed by physical therapists was more effective than no treatment, sham DN, and other therapies for reducing pain.

IMPACT

DN is commonly used by physical therapists to treat musculoskeletal pain, and it is very important for physical therapists to know the clinical conditions and time periods for which DN is effective in reducing pain in their patients.

Effects of Dry Needling on Spasticity and Range of Motion: A Systematic Review

IMPORTANCE

This systematic review summarizes existing studies on dry needling for spasticity and range of motion (ROM) and discusses its potential for use as an occupational therapy intervention.

OBJECTIVE

To examine existing studies on the effects of dry needling on spasticity and ROM.

DATA SOURCES

Article citations and abstracts from Scopus, Cochrane Library, PubMed, CINAHL, and a university library search.

STUDY SELECTION AND DATA COLLECTION

Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were used in abstracting data. Peer-reviewed journal articles published in English between January 2007 and June 2019 were searched. Of 270 identified studies, 10 met the inclusion criteria. Studies were divided into categories on the basis of outcome measures (Modified Modified Ashworth Scale and ROM). Pain outcome measures were excluded because a systematic review addressing this outcome has recently been completed.

FINDINGS

Strong evidence was found to support the use of dry needling to decrease spasticity and increase ROM.

CONCLUSIONS AND RELEVANCE

This systematic review suggests that dry needling is an effective physical agent modality to decrease spasticity and increase ROM, both of which are potentially beneficial to functional outcomes.

WHAT THIS ARTICLE ADDS

This article provides information that may be helpful in determining the appropriateness of dry needling as an occupational therapy intervention.

Dry Needling and Photobiomodulation Decreases Myofascial Pain in Trapezius of Women: Randomized Blind Clinical Trial

OBJECTIVE

The purpose of this study was to assess whether dry needling (DN) added to photobiomodulation (PBM) has effects on the treatment of active myofascial trigger points in the upper trapezius.

METHODS

This study was a randomized clinical trial, with 43 participants divided into 3 groups: DN and PBM (DNP), DN, and DN outside of the trigger point (DNout). Each group received 1 session of DN followed by PBM therapy with the machine turned on or off. Pain, disability, pain pressure threshold, and muscle activity were assessed before the intervention and afterward at intervals of 10 minutes, 30 minutes, 1 week, and 1 month.

RESULTS

Pain decreased after intervention in the DNP and DNout groups, with mean differences, respectively, of 1.33 cm (95% confidence interval [CI], 0.019-2.647) and 2.78 cm (95% CI, 1.170-2.973). Scores for the disability questionnaire decreased in all groups after intervention (F = 36.53, P < .0001) after the intervention, with mean differences of 3.8 points in the DNP group (95% CI, 1.082-5.518), 3.57 in the DN group (95% CI, 0.994-6.149), and 5.43 in the DNout group (95% CI, 3.101-7.756). There were no significant differences between or within groups in pain pressure threshold (F = 2.14, P = .139), with mean differences after 30 minutes of 0.139 kgf for the DNP group (95% CI, -0.343 to 0.622), 0.273 for the DN group (95% CI, -0.661 to 1.209), and -0.07 for the DNout group (95% CI, -0.465 to 0.324). Muscle activation for the DN group increased 8.49% after the intervention, where for the DNP group it decreased 11.5%, with a significant difference between groups.

CONCLUSION

DN added to PBM presented similar results compared to DNout and DN. In this sample, the effects of the application of DN outside of the trigger point had better effects on pain and disability scores than DN applied directly on the trigger point.

Effectiveness of Dry Needling for Myofascial Trigger Points Associated with Neck Pain Symptoms: An Updated Systematic Review and Meta-Analysis

Our aim was to evaluate the effect of dry needling alone as compared to sham needling, no intervention, or other physical interventions applied over trigger points (TrPs) related with neck pain symptoms. Randomized controlled trials including one group receiving dry needling for TrPs associated with neck pain were identified in electronic databases. Outcomes included pain intensity, pain-related disability, pressure pain thresholds, and cervical range of motion. The Cochrane risk of bias tool and the Physiotherapy Evidence Database (PEDro) score were used to assessed risk of bias (RoB) and methodological quality of the trials. The quality of evidence was assessed by using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Between-groups mean differences (MD) and standardized mean differences (SMD) were calculated (3) Twenty-eight trials were finally included. Dry needling reduced pain immediately after (MD -1.53, 95% CI -2.29 to -0.76) and at short-term (MD -2.31, 95% CI -3.64 to -0.99) when compared with sham/placebo/waiting list/other form of dry needling and, also, at short-term (MD -0.51, 95% CI -0.95 to -0.06) compared with manual therapy. No differences in comparison with other physical therapy interventions were observed. An effect on pain-related disability at the short-term was found when comparing dry needing with sham/placebo/waiting list/other form of dry needling (SMD -0.87, 95% CI -1.60 to -0.14) but not with manual therapy or other interventions. Dry needling was effective for improving pressure pain thresholds immediately after the intervention (MD 55.48 kPa, 95% CI 27.03 to 83.93). No effect on cervical range of motion of dry needling against either comparative group was found. No between-treatment effect was observed in any outcome at mid-term. Low to moderate evidence suggests that dry needling can be effective for improving pain intensity and pain-related disability in individuals with neck pain symptoms associated with TrPs at the short-term. No significant effects on pressure pain sensitivity or cervical range of motion were observed. Registration number: OSF Registry-https://doi.org/10.17605/OSF.IO/P2UWD.

Effects of Dry Needling Technique Into Trigger Points of the Sternocleidomastoid Muscle in Migraine Headache: A Randomized Controlled Trial

OBJECTIVE

The study aimed to investigate the effect of dry needling into trigger points of the sternocleidomastoid muscle in migraine headache patients.

DESIGN

Forty subjects with a migraine headache, originating from myofacial trigger points into the sternocleidomastoid muscle (20 subjects in dry needling group and 20 subjects in control group) volunteered to participate in this study. The subjects in the treatment group received three sessions of dry needling in the myofascial trigger point region. Headache frequency, headache intensity, headache duration, drug consumption, muscle thickness, pressure pain threshold, and cervical range of motion were assessed before, immediately after intervention, and at 1-mo follow-up period. In addition, this article was extracted from Iranian Register of Clinical Trials Number IRCT20171219037956N1.

RESULTS

The experimental group showed significant reduction in the headache parameters immediately after the intervention and at 1-mo follow-up, as compared with the control group. The pressure pain threshold of sternocleidomastoid muscle, cervical range of motion, and muscle thickness significantly increased in the dry needling group in comparison with the control group (P < 0.001).

CONCLUSIONS

The application of dry needling technique caused an improvement in symptoms of migraine patients. Therefore, this technique may be prescribed for treating migraine patients with myofacial trigger points in the sternocleidomastoid muscle.

Mental practice in isolation improves cervical joint position sense in patients with chronic neck pain: a randomized single-blind placebo trial

Objective

The main objective of this trial was to assess whether action observation (AO) training and motor imagery (MI) produced changes in the cervical joint position sense (CJPS) both at the end of the intervention and 10 min postintervention compared with a placebo intervention in patients with nonspecific chronic neck pain (NSCNP).

Methods

A single-blind placebo clinical trial was designed. A total of 30 patients with NSCNP were randomly assigned to the AO group, MI group or placebo observation (PO) group. CJPS in flexion, extension and rotation movements in both planes were the main variables.

Results

The results obtained in the vertical plane showed that the AO group obtained greater improvements than the PO group in the CJPS in terms of cervical extension movement both at the end of the intervention and 10 min postintervention (p = .001, d = 1.81 and p = .004, d = 1.74, respectively), and also in cervical flexion movement, although only at 10 min after the intervention (p = .035, d = 0.72). In addition, the AO group obtained greater improvements than the MI group in the CJPS only at the end of the intervention in cervical extension movement (p = .041, d = 1.17). Regarding the left rotation cervical movement, both the MI and AO groups were superior to the PO group in both planes at the end of the intervention (p < .05, d > 0.80).

Conclusions

Although both AO and MI could be a useful strategy for CJPS improvement, the AO group showed the strongest results. The therapeutic potential of the application of mental practice in a clinical context in the early stages of rehabilitation of NSCNP should be considered.
