Background: To evaluate the effect of trigger point dry needling alone or as an adjunct with other interventions on pain and related disability in people with knee pain. Methods: Several electronic databases were searched for randomized controlled trials where at least one group received dry needling for knee pain. Studies had to include human subjects and collect outcomes on pain and pain-related disability in musculoskeletal knee pain. Data were extracted by two reviewers. The risk of bias was assessed by the Cochrane Guidelines, methodological quality was assessed with the Physiotherapy Evidence Database (PEDro) score, and the quality of evidence by using the GRADE approach. Standardized mean differences (SMD) were calculated. Results: Ten studies (six patellofemoral pain, two knee osteoarthritis, two post-surgery knee pain) were included. The meta-analysis found moderate effect sizes of dry needling for reducing pain (SMD −0.53, 95% CI −0.87 to −0.19) and improving related disability (SMD −0.58, 95% CI −1.08 to −0.09) as compared to a comparison group at short-term. The main effect was observed for patellofemoral pain (SMD −0.64, 95% CI −1.17 to −0.11). No significant effects were observed at mid- or long-term follow-ups. The risk of bias was generally low, but the heterogenicity and the imprecision of the results downgraded the level of evidence. Conclusion: Low to moderate evidence suggests a positive effect of trigger point dry needling on pain and related disability in patellofemoral pain, but not knee osteoarthritis or post-surgery knee pain, at short-term. More high-quality trials investigating long-term effects are clearly needed.
Objective The purpose of this study was to evaluate the effects of trigger point (TrP) dry needling alone or as an adjunct to other interventions on pain intensity and related disability in nontraumatic shoulder pain. Methods Ten databases were searched from inception to January 2020 for randomized clinical trials in which at least 1 group received TrP dry needling for shoulder pain of musculoskeletal origin with outcomes collected on pain intensity and related disability. Data extraction including participant and therapist details, interventions, blinding strategy, blinding assessment outcomes, and results were extracted by 2 reviewers. The risk of bias (RoB, Cochrane Guidelines), methodological quality (PEDro score), and evidence level (GRADE approach) were assessed. The search identified 551 publications with 6 trials eligible for inclusion. Results There was moderate quality evidence that TrP dry needling reduces shoulder pain intensity with a small effect (MD = −0.49 points, 95% CI = −0.84 to −0.13; SMD = −0.25, 95% CI = −0.42 to −0.09) and low quality evidence that TrP dry needling improves related disability with a large effect (MD = −9.99 points, 95% CI -15.97 to −4.01; SMD = −1.14, 95% CI -1.81 to −0.47) as compared to a comparison group. The effects on pain were only found at short-term. The RoB was generally low, but the heterogenicity of the results downgraded the evidence level. Conclusions Moderate- to low-quality evidence suggests positive effects of TrP dry needling for pain intensity (small effect) and pain-related disability (large effect) in nontraumatic shoulder pain of musculoskeletal origin, mostly at short term. Future clinical trials investigating long-term effects are needed. Impact Dry needling is commonly used for the management of musculoskeletal pain. This is the first meta-analysis to examine the effects of dry needling on nontraumatic shoulder pain.
Background and Objective To evaluate the effects of percutaneous electrical stimulation (PENS) alone or as an adjunct with other interventions on pain and related disability in musculoskeletal pain conditions. Databases and Data Treatment Search of MEDLINE, EMBASE, AMED, CINAHL, EBSCO, PubMed, PEDro, Cochrane Library, SCOPUS and Web of Science databases. Randomized controlled trials where at least one group received any form of PENS for musculoskeletal condition. Studies had to include humans and collect outcomes on pain and related disability in musculoskeletal pain. Risk of bias was assessed by the Cochrane Guidelines, the quality of evidence by using the GRADE approach. Standardized mean differences (SMD) were calculated. Results Sixteen studies were included and included heterogeneous musculoskeletal conditions with short‐ or midterm follow‐ups. PENS alone had a large effect (SMD −1.22, 95% CI −1.66 to −0.79) on pain and a small effect (SMD −0.33, 95% CI −0.61 to −0.06) on related disability at short‐term as compared with sham. A moderate effect of PENS alone (SMD −0.71, 95% CI −1.23 to −0.19) on pain when compared with other interventions was observed. The inclusion of PENS with other interventions had a moderate effect for decreasing pain at short‐ (SMD −0.70, 95% CI −1.02 to −0.37) and midterm (SMD −0.68, 95% CI −1.10 to −0.27). No effect at midterm (SMD −0.21, 95% CI −0.52 to 0.10) on related disability was seen. The risk of bias was generally low; but the heterogenicity of the results downgraded the level of evidence. Conclusion There is low level of evidence suggesting the effects of PENS alone or in combination for pain, but not related disability, in musculoskeletal pain. Level of Evidence Therapy, level 1a. Registration number: CRD42019131331. Significance This meta‐analysis investigating the effectiveness of PENS for the management of pain and related disability in musculoskeletal pain conditions found that PENS could decrease level of pain intensity but not relateddisability in musculoskeletal pain disorders.
Objective To evaluate the effects of ultrasound-guided percutaneous electrolysis alone or as an adjunct to other interventions on pain and pain-related disability for musculoskeletal pain conditions. Databases and Data Treatment Search of MEDLINE database, Allied and Complementary Medicine Database, EMBASE database, Cumulative Index to Nursing & Allied Health Literature database, EBSCO database, PubMed database, Physiotherapy Evidence Database, Cochrane Library database, Scopus database, and Web of Science database. Randomized controlled trials in which at least one group received ultrasound-guided percutaneous electrolysis for treatment of musculoskeletal pain. To be eligible, studies had to include humans and collect outcomes on pain intensity and pain-related disability for musculoskeletal pain syndromes. Data were extracted by two reviewers. The risk of bias was assessed by the Cochrane Guidelines and the quality of evidence was reported using the Grading of Recommendations Assessment, Development and Evaluation approach. Standardized mean differences (SMDs) and random effects were calculated. Results Ten studies were included. The meta-analysis found that ultrasound-guided percutaneous electrolysis reduced the mean pain intensity by –2.06 (95% confidence interval [CI], –2.69 to –1.42) and the pain intensity as assessed with a visual analog scale or a numeric pain rating scale with a large size effect (SMD = –1.15; 95% CI, –1.48 to –0.81) and also improved pain-related disability with a large size effect (SMD = 0.95; 95% CI, 0.73–1.18) as compared with comparison groups. No differences in effect sizes were found among the short-term, midterm, and long-term follow-ups. The risk of bias was generally low, but the heterogeneity of the overall result downgraded the evidence level. Trials included heterogeneous musculoskeletal pain conditions and short-term, midterm, and long-term follow-ups. Conclusion Moderate evidence suggests positive effects of ultrasound-guided percutaneous electrolysis for pain and pain-related disability in musculoskeletal pain conditions relative to a comparison group in the short term, midterm, and long term.
Objective: This meta-analysis evaluated the effect of dry needling alone or combined with other treatment interventions on pain, related-disability, pressure pain sensitivity, and strength in people with lateral epicondylalgia of musculoskeletal origin. Data Sources: MEDLINE, CINAHL, PubMed, PEDro, Cochrane Library, SCOPUS and Web of Science databases from their inception to 5 April 2020. Review Methods: Randomized controlled trials collecting outcomes on pain, related-disability, pressure pain thresholds, or strength where one group received dry needling for lateral epicondylalgia of musculoskeletal origin. The risk of bias was assessed by the Cochrane Guidelines, methodological quality was assessed with the PEDro score, and the quality of evidence by using the GRADE approach. Results: Seven studies including 320 patients with lateral epicondylalgia were included. The meta-analysis found that dry needling reduced pain intensity (SMD ‒1.13, 95%CI ‒1.64 to ‒0.62) and related-disability (SMD ‒2.17, 95%CI ‒3.34 to ‒1.01) with large effect sizes compared to a comparative group. Dry needling also increased pressure pain thresholds with a large effect size (SMD 0.98, 95%CI 0.30 to 1.67) and grip strength with a small size effect (SMD 0.48, 95%CI 0.16 to 0.81) when compared to a comparative group. The most significant effect was at short-term. The risk of bias was generally low, but the heterogenicity of the results downgraded the evidence level. Conclusion: Low to moderate evidence suggests a positive effect of dry needling for pain, pain-related disability, pressure pain sensitivity and strength at short-term in patients with lateral epicondylalgia of musculoskeletal origin. Level of Evidence: Therapy, level 1a. Registration number: OSF Registry - https://doi.org/10.17605/OSF.IO/ZY3E8
