Rosacea treatment with mussel adhesive protein delivered via microneedling: In vivo and clinical studies

BACKGROUND

Rosacea is a prevalent chronic dermatological condition marked by facial inflammation and erythema, significantly compromising the quality of life for affected individuals. Current treatment methods for rosacea are not considered ideal because of the complex etiology of the disease. Mussel adhesive protein (MAP) is a glycoprotein derived from the foot gland of mussels. The protein exhibits anti-inflammatory properties, relieves skin itching, and promotes wound healing.

AIMS

We aimed to explore the feasibility of using MAP administered via microneedle delivery for treating rosacea and the potential molecular mechanism involved.

MATERIALS AND METHODS

The therapeutic effect and mechanism of MAP microneedle delivery in an LL-37-induced rosacea-like mouse model were observed using morphological and histological methods. Twenty-seven patients with erythematotelangiectatic rosacea (ETR) underwent treatment once every 1 month, with three treatments constituting one treatment course. The therapeutic effect was evaluated by comparing the clinical images taken at baseline, after the first treatment course, and after the second treatment course. The red value, CEA, and GFSS score were also calculated.

RESULTS

In response to the microneedle delivery of MAP, innate immunity, inflammatory infiltration, and abnormal neurovascular regulation improved significantly in rosacea-like mice. In the clinical experiments, the microneedle delivery of MAP significantly improved the symptoms of erythema, flushing, and telangiectasia in patients with ETR, and no obvious adverse reactions were observed.

CONCLUSIONS

MAP delivered by microneedling is effective and safe for treating ETR.

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

PURPOSE

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

MATERIAL AND METHODS

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

RESULTS

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

CONCLUSION

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

Evaluation of microneedling depth of penetration in management of atrophic acne scars: a split-face comparative study

BACKGROUND

Microneedling is a technique of repeated puncturing or drilling of the skin to induce repair and collagen induction. There are many reported important factors determining the efficacy of microneedling treatment. The extent of injury needed to produce the desired effect in each condition is one of these important factors.

OBJECTIVES

We designed the present split-face comparative study to evaluate the use and effectiveness of two different depths of penetration of Dermapen needles in the management of atrophic postacne scars.

PATIENTS AND METHODS

The present study involved 14 subjects with atrophic postacne scars. In each patient, both sides of the face were treated with six sessions of microneedling, using Dermapen at 2-week intervals. A split-face study design was performed. The right (Rt) side of the face was treated with Dermapen using 2.5 mm needle length, while the left (Lt) side was treated using 1.5 mm needle length.

RESULTS

There was a significantly better percentage of improvement of acne scars on the Rt side of the face compared to the Lt side (P = 0.02) after six sessions. Both sides of the face showed improvement of collagen bundles and elastic fibers characteristics after six sessions.

CONCLUSIONS

The use of 2.5 mm depth proved to be more effective both clinically and histologically in the management of atrophic postacne scars.

Microneedling versus microcoring: A review of percutaneous collagen induction for the face and neck

BACKGROUND

Microneedling (MN) and microcoring (MCT) are both methods used for percutaneous collagen induction. This minimally invasive technique involves creating controlled damage in cutaneous tissue to induce neocollagenesis and neoelastogenesis. MN utilizes solid microneedles and is commonly combined with radiofrequency (RF) to add thermal energy, while MCT involves hollow microneedles capable of removing excess tissue without inducing scar formation.

AIMS

The purpose of this review was to summarize recent literature for MN and MCT, with the goal of assisting clinical decision making regarding the use of these technologies.

METHODS

PubMed search was conducted for relevant articles published within the last 10 years. Scoping literature review was then performed with pertinent findings reported.

RESULTS

Existing literature investigating MCT is sparse. Limited data on in vivo, human effects of this technology exist. Two out of 14 studies in this review pertained to MCT.

CONCLUSION

Additional high-powered clinical studies are needed to guide future cosmetic treatments with MN and MCT.

Efficacy and safety of combined microneedling therapy for androgenic alopecia: A systematic review and meta-analysis of randomized clinical trials

OBJECTIVE

To provide dermatologists with more clinical experience in treating androgenetic alopecia, we evaluated the effect and safety of combined microneedling therapy for androgenetic alopecia.

METHODS

Studies on combined microneedling for hair loss were comprehensively searched by us in PubMed, Excerpta Medica Database, and the Cochrane Library Database. The literature search spanned the period from 2012 to 2022. Inclusion and exclusion criteria were developed, and the literature was screened according to this criteria. The Cochrane Risk of Bias Tool was used to assess the quality of the studies. The researcher applied Revman 5.3 and Stata 15.1 software to analyze the data after extracting information from the data.

RESULTS

Finally, 13 RCTs involving 696 AGA patients were included to compare the clinical effectiveness and adverse events of combined MN therapy with single MN therapy or single drug therapy for AGA. The results of meta-analysis showed as follows: (1) Hair density and diameter changes: The combined MN group was significantly better than any single treatment group, and the differences were statistically significant (MD = 13.36, 95% CI = [8.55, 18.16], Z = 5.45, p < 0.00001; MD = 18.11, 95% CI = [13.70, 22.52], Z = 8.04, p < 0.00001; MD = 13.36, 95% CI = [8.55, 18.16], Z = 5.45, p < 0.00001; MD = 2.50, 95% CI = [0.99, 4.02], Z = 3.23, p = 0.001); (2) the evaluation of satisfaction for efficacy: The doctor satisfaction rating of the combined MN group was significantly higher than that of any single treatment group, with statistical difference (RR = 2.03, 95% CI = [1.62, 2.53], Z = 6.24, p < 0.00001). The difference between the two groups regarding patients satisfaction was not significant (RR = 3.44, 95% CI = [0.67, 17.59], Z = 1.49, p = 0.14). (3) Safety: There was no statistical difference in the incidence of adverse reactions between combination therapy and monotherapy (RR = 0.83, 95% CI = [0.62, 1.12], Z = 1.22, p = 0.22).

CONCLUSION

The combined MN group showed statistically significant improvement in hair density and diameter, and good safety compared with monotherapy.

Efficacy and safety of fractional micro-needling radiofrequency for the treatment of enlarged pores on the cheeks of a chinese cohort: a retrospective study

To explore the efficacy and safety of fractional micro-needling radiofrequency (FMRF) in the treatment of enlarged pores on the cheek in a Chinese cohort. Patients with enlarged facial pores who underwent FMRF between January 2020 and December 2022 were included in this study. Blinded clinical assessments were performed by two independent dermatologists using a six-grade photographic enlarged pore scale and a quartile grading scale. Patients were asked to rate the degree of pain related to treatment on a visual analog scale (VAS), with scores ranging from 0 (no pain) to 10 (worst pain ever). A paired t-test was used to analyze the six-grade photographic enlarged pore scores. A total of 22 patients received three consecutive sessions of FMRF treatment, with intervals of 1-3 months, and underwent follow-up as scheduled. The mean six-grade photographic enlarged score was 3.55 ± 0.96 at baseline, while the score decreased significantly to 2.59 ± 0.59 after three treatment sessions (P < 0.05). The improvement score of the patients, assessed by two independent dermatologists, was 2.31 ± 0.71, according to the quartile grading scale. The mean VAS score was 6.42 ± 1.44. FMRF is effective and safe for the treatment of enlarged facial pores after three sessions.

Treatment of Palmar Hyperhidrosis With Radiofrequency Microneedling-Based on Ultrasound Measurements

This study addresses the treatment of palmar hyperhidrosis, which has been difficult to manage. A new treatment has been developed using radiofrequency microneedling to reduce sweating non-surgically by ablating sweat glands. Based on ultrasound measurements of the dermis and precise microneedling damage, effective energy was applied to locate the sweat glands and disabled their function. Radiofrequency microneedling with ultrasound can safely and effectively treat hyperhidrosis in a minimally invasive way.

Dry Needling Versus Manual Therapy for Patients With Mechanical Neck Pain: A Randomized Controlled Trial

OBJECTIVE: To compare the short- and intermediate-term effects of dry needling to manual therapy on pain, disability, function, and patient-perceived improvement in patients with mechanical neck pain. DESIGN: A single (therapist) blinded randomized controlled trial. METHODS: Seventy-eight patients (mean ± SD age, 50.74 ± 13.81) were randomly assigned to one of the 2 groups: (1) dry needling and therapeutic exercises (DN + Exercises) and (2) manual therapy and therapeutic exercises (MT + Exercises). Both groups received 7 treatment sessions over a maximum of 6 weeks. Outcome measures, collected at baseline, 2 weeks, discharge (7th treatment session), and 3 months after discharge, were as follows: Neck Disability Index (NDI), numeric pain-rating scale (NPRS), Patient-Specific Functional Scale (PSFS), global rating of change (GROC), Fear-Avoidance Belief Questionnaire (FABQ), and Deep Neck Flexor Endurance Test (DNFET). Data were analyzed with mixed-model analysis of covariance (ANCOVA), using pretest scores as covariates, and a Mann-Whitney U test for GROC scores. RESULTS: The ANCOVA revealed significant group-by-time interaction for all variables. Significant between-group differences, favoring MT + Exercises, were observed at all 3 time points on the NDI (2 weeks: F1,446 = 172.68, P≤.001, [Formula: see text] = .27; discharge: F1,446 = 254.15, P≤.001, [Formula: see text] = .36; and 3 months: F1,446 = 339.40, P≤.001, [Formula: see text] = .43). Results for the MT + Exercises group exceeded recommended minimal clinically important difference for all variables, at all follow-up points. CONCLUSION: MT + Exercises was more effective, both in the short term and intermediate term, than DN + Exercises in reducing pain, disability, and improving function in patients with mechanical neck pain.

Effects of thumb-tack needling combined with sporting on older adult patients with knee osteoarthritis: A randomized active-control clinical trial

AIM

The aim of this clinical study was to explore the effects of thumb-tack needling combined with sporting (TTNS) therapy on the improvement of pain and joint function in older adult patients with knee osteoarthritis (KOA).

METHODS

A total of 120 older adult patients with KOA were randomly assigned to receive TTNS therapy or medicine treatment (Med group) only for 1 month. The patients were followed up for 3 months and clinical efficacies were evaluated using a visual analog scale to assess pain, the Lequesne scoring system to assess motor function, and the Western Ontario and McMaster University Osteoarthritis Index to assess KOA severity. Blood was collected to measure the levels of interleukin-6 and tumor necrotic factor-alpha using enzyme-linked immunosorbent assay.

RESULTS

The data suggested that TTNS therapy resulted in a significantly higher clinical efficacy (P = 0.012). Visual analog scale score, Lequesne index, and Western Ontario and McMaster University Osteoarthritis Index of the TTNS group at the time of post-treatment (1 month) and post-follow-up (3 months) were also lower compared with the Med group. Patients in the TTNS group also showed lower levels of serum tumor necrotic factor-alpha and interleukin-6.

CONCLUSIONS

TTNS therapy is more efficacious than pharmacological treatment in improving the clinical outcomes of patients with KOA, which suggests its clinical utility in the management of KOA. Geriatr Gerontol Int 2024; 24: 415-420.

Ultrasound verification of palpation-based dry needling techniques of rotator cuff muscles: a prospective feasibility trial

OBJECTIVES

The primary purpose of this study is to investigate the feasibility of using ultrasound to verify the placement of narrow-gauge dry needles within the supraspinatus and infraspinatus muscles utilizing palpation-based dry needle techniques.

METHODS

This is a prospective observational study with 10 participants recruited. Each participant had a dry needle placed within the infraspinatus and supraspinatus muscles by a trained physical therapist utilizing palpation-based methods. Following needle placement, ultrasound examination was then performed to determine the feasibility of needle tip visualization within the targeted tissues.

RESULTS

The needle tip was successfully visualized on ultrasound in 19/20 cases. The needle tip accurately resided in the targeted muscle tissue in each of the 19 cases it was successfully visualized.

CONCLUSIONS

Narrow-gauge dry needles used in physical therapy practice can be consistently visualized in the supraspinatus and infraspinatus muscles using ultrasound imaging. Also, the palpation method utilized is an accurate means of guiding dry needles into the targeted rotator cuff muscles. These are significant findings because most physical therapy clinics do not have the benefit of real-time imaging guidance and must rely solely on palpation-based needling methods.

Safety of dry needling in stroke patients: a scoping review

INTRODUCTION

Spasticity is a common problem in stroke patients. Treatments of spasticity often have side effects or are insufficiently effective. Dry needling (DN) has been proposed as a potential additional option to consider in the multimodal treatment of post-stroke spasticity, although questions about its safety remain. The goal of this study is to assess the safety of DN in stroke patients.

EVIDENCE ACQUISITION

A systematic search in Medline, Embase, The Cochrane Library, Web of Science, CIHNAL and PEDro was conducted in June 2023. Two reviewers independently screened abstracts according to the eligibility criteria.

EVIDENCE SYNTHESIS

Twenty-five articles were included in this review. Only six studies reported adverse events, all of which were considered minor. None of the included studies reported any serious adverse events. In four of the included studies anticoagulants were regarded as contra-indicative for DN. Anticoagulants were not mentioned in the other included studies.

CONCLUSIONS

There is a paucity of literature concerning the safety of DN in stroke patients. This review is the first to investigate the safety of DN in stroke patients and based on the results there is insufficient evidence regarding the safety of DN in stroke patients.

CLINICAL REHABILITATION IMPACT

Although DN could be a promising treatment in post-stroke spasticity, further research is indicated to investigate its mechanism of action and its effect on outcome. However, before conducting large clinical trials to assess outcome parameters, the safety of DN in stroke patients must be further investigated.

Functional connectivity patterns are altered by low back pain and cause different responses to sham and real dry needling therapies: a systematic review of fMRI studies

BACKGROUND

There is a relationship between low back pain (LBP) and central nervous system dysfunction. Needling therapies (e.g. acupuncture, dry needling) are proposed to impact the nervous system, however their specific influence is unclear.

PURPOSE

Determine how needling therapies alter functional connectivity and LBP as measured by functional magnetic resonance imaging (fMRI).

METHODS

Databases were searched following PRISMA guidelines. Studies using fMRI on individuals with LBP receiving dry needling or acupuncture compared to control or sham treatments were included.

RESULTS

Eight studies were included, all of which used acupuncture. The quality of studies ranged from good (n = 6) to excellent (n = 2). After acupuncture, individuals with LBP demonstrated significant functional connectivity changes across several networks, notably the salience, somatomotor, default mode network (DMN) and limbic networks. A meta-analysis demonstrated evidence of no effect to potential small effect of acupuncture in reducing LBP (SMD -0.28; 95% CI: -0.70, 0.13).

CONCLUSION

Needling therapies, like acupuncture, may have a central effect on patients beyond the local tissue effects, reducing patients' pain and disability due to alterations in neural processing, including the DMN, and potentially other central nervous system effects. The meta-analysis should be interpreted with caution due to the narrow focus and confined sample used.

Efficacy of trigger point dry needling on pain and function of the hip joint: a systematic review of randomized clinical trials

OBJECTIVE

The objective of this study was to assess the evidence for the impact of dry needling (DN) on hip pain and function.

METHODS

Medline/PubMed, Embase, Scopus, Web of Science and Cochrane CENTRAL databases were searched systematically through June 2022 for randomized clinical trials (RCTs) investigating the impact of DN on hip pain and function. Version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2) was used to assess risk of bias. Descriptive analysis was conducted to explain the outcomes and adverse events of DN in hip joint diseases. Meta-analysis was not feasible due to significant heterogeneity.

RESULTS

A total of seven eligible studies (including 273 patients) were included out of 2152 screened records. Five studies were in participants with hip osteoarthritis (OA; n = 3), greater trochanteric pain syndrome (GTPS; n = 1) or piriformis syndrome (n = 1); the other two studies were conducted in healthy athletes (n = 2). Two articles assessed changes in participants' short-term visual analog scale (VAS) scores (<1 week), one of which showed that DN significantly reduced pain (P < 0.05). One-week VAS scores were analyzed in three studies, all of which demonstrated reduced scores following DN (P < 0.05). Hip range of motion (ROM) and muscle force were also improved following DN. No serious side effects were reported.

CONCLUSION

DN may be safe and effective at relieving hip pain and improving hip function. DN performs significantly better than several different types of control intervention (including sham DN, no treatment, corticosteroid injections and laser). Strong evidence (high degree of certainty around the results) is lacking, and future studies should ideally use longer follow-up periods and larger sample sizes.

Spinal manipulation and electrical dry needling as an adjunct to conventional physical therapy in patients with lumbar spinal stenosis: a multi-center randomized clinical trial

BACKGROUND CONTEXT

Nonoperative management of lumbar spinal stenosis (LSS) includes activity modification, medication, injections, and physical therapy. Conventional physical therapy includes a multimodal approach of exercise, manual therapy, and electro-thermal modalities. There is a paucity of evidence supporting the use of spinal manipulation and dry needling as an adjunct to conventional physical therapy in patients with LSS.

PURPOSE

This study aimed to determine the effects of adding thrust spinal manipulation and electrical dry needling to conventional physical therapy in patients with LSS.

STUDY DESIGN/SETTING

Randomized, single-blinded, multi-center, parallel-group clinical trial.

PATIENT SAMPLE

One hundred twenty-eight (n=128) patients with LSS from 12 outpatient clinics in 8 states were recruited over a 34-month period.

OUTCOME MEASURES

The primary outcomes included the Numeric Pain Rating Scale (NPRS) and the Oswestry Disability Index (ODI). Secondary outcomes included the Roland Morris Disability Index (RMDI), Global Rating of Change (GROC), and medication intake. Follow-up assessments were taken at 2 weeks, 6 weeks, and 3 months.

METHODS

Patients were randomized to receive either spinal manipulation, electrical dry needling, and conventional physical therapy (MEDNCPT group, n=65) or conventional physical therapy alone (CPT group, n=63).

RESULTS

At 3 months, the MEDNCPT group experienced greater reductions in overall low back, buttock, and leg pain (NPRS: F=5.658; p=.002) and related-disability (ODI: F=9.921; p<.001; RMDI: F=7.263; p<.001) compared to the CPT group. Effect sizes were small at 2 and 6 weeks, and medium at 3 months for the NPRS, ODI, and RMDI. At 3 months, significantly (p=.003) more patients in the MEDNCPT group reported a successful outcome (GROC≥+5) than the CPT group.

CONCLUSION

Patients with LSS who received electrical dry needling and spinal manipulation in addition to impairment-based exercise, manual therapy and electro-thermal modalities experienced greater improvements in low back, buttock and leg pain and related-disability than those receiving exercise, manual therapy, and electro-thermal modalities alone at 3 months, but not at the 2 or 6 week follow-up.

Effects of the elongated needling combined with routine acupuncture therapy in the patients with post-stroke hemiplegia and central pain： a randomized controlled trial

OBJECTIVES

To investigate the effects of the elongated needling at the points of hand and foot yang meridians and the Governor Vessel combined with the routine acupuncture therapy on pain, balance function and muscle strength of the patients with post-stroke hemiplegia and central post-stroke pain (CPSP), and to investigate whether its therapeutic mechanism is related to antioxidant damage.

METHODS

Ninety-four patients with post-stroke hemiplegia and CPSP admitted from March 2020 to September 2021 were divided into a trial group (47 cases, 1 cases dropped out) and a control group (47 cases 3 cases dropped out). In the control group, the rehabilitation exercise combined with routine acupuncture therapy was used, and in the trial group, on the base of the treatment as the control group, the elongated needling at the points of hand and foot yang meridians and the Governor Vessel was supplemented. In the two groups, the treatment was given once daily, and 1 course of treatment was composed of 14 days, a total of 6 courses were required in the trial. Separately, before treatment, and 1, 2 and 3 months after treatment, between two groups, the score of visual analogue scale (VAS) and that of Berg balance scale (BBS), as well as muscle strength were compared；the neural function was evaluated using the national institutes of health stroke scale (NIHSS) and the serum contents of nitricoxide synthase (NOS), superoxide dismutase (SOD) and malondialdehyde (MDA) were detected by ELISA in the patients.

RESULTS

Compared with those before treatment, VAS score and NIHSS score were all decreased (P<0.05) in the trial and the control group after 1 month, 2 months and 3 months of treatment, and BBS score was increased (P<0.05)；and the case proportion of muscle strength grade 4 and 5 was higher (P<0.05) in the trial group. In the control group, the proportion of grade 4 increased after treatment for 2 months (P<0.05), and that of grade 4 and 5 increased after treatment for 3 months (P<0.05). The serum contents of NOS and SOD were increased (P<0.05), and MDA was decreased (P<0.05) after 3 months of treatment in the two groups. In comparison with the control group at the same time point, VAS score and NIHSS score were lower (P<0.05), BBS score higher (P<0.05) and the muscle strength grade was improved (P<0.05, P<0.01) after 1, 2 and 3 months of treatment, respectively；and the serum contents of NOS and SOD increased (P<0.05), and MDA decreased (P<0.05) after 3 months of treatment in the trial group.

CONCLUSIONS

The elongated needling at the points of hand and foot yang meridians and the Governor Vessel, combined with the routine acupuncture therapy alleviates CPSP, improves balance and muscle strength and promotes the recovery of neural function in the patients with post-stroke hemiplegia, the mechanism may be related to antioxidant damage.

Effects of dry needling on spasticity, cortical excitability, and range of motion in a patient with multiple sclerosis: a case report

BACKGROUND

Dry needling is an intervention used by physiotherapists to manage muscle spasticity. We report the effects of three sessions of dry needling on ankle plantar flexor muscle spasticity and cortical excitability in a patient with multiple sclerosis.

CASE PRESENTATION

The patient was a 40-year-old Iranian woman with an 11-year history of multiple sclerosis. The study outcomes were measured by the modified modified Ashworth scale, transcranial magnetic stimulation parameters, and active and passive ankle range of motion. They were assessed before (T0), after three sessions of dry needling (T1), and at 2-week follow-up (T2). Our result showed: the modified modified Ashworth scale was improved at T2 from, 2 to 1. The resting motor threshold decreased from 63 to 61 and 57 at T1 and T2, respectively. The single test motor evokes potential increased from 76.2 to 78.3. The short intracortical inhibition increased from 23.6 to 35.4 at T2. The intracortical facilitation increased from 52 to 76 at T2. The ankle active and passive dorsiflexion ROM increased ~ 10° and ~ 6° at T2, respectively.

CONCLUSION

This case study presented a patient with multiple sclerosis who underwent dry needling of ankle plantar flexors with severe spasticity, and highlighted the successful use of dry needling in the management of spasticity, ankle dorsiflexion, and cortical excitability. Further rigorous investigations are warranted, employing randomized controlled trials with a sufficient sample of patients with multiple sclerosis.

Parallel needling technique for peripheral facial paralysis with qi deficiency and blood stasis: a randomized controlled trial

OBJECTIVES

To observe the clinical efficacy of the parallel needling technique for peripheral facial paralysis with qi deficiency and blood stasis.

METHODS

Sixty-two patients with peripheral facial paralysis of qi deficiency and blood stasis were randomly assigned to a parallel needling group and a conventional acupuncture group, with 31 patients in each group. The conventional acupuncture group received needling at Yangbai (GB 14), Quanliao (SI 18), Jiache (ST 6), Dicang (ST 4), Yifeng (TE 17) on the affected side, Hegu (LI 4) on the healthy side, and bilateral Zusanli (ST 36), Sanyinjiao (SP 6), Xuehai (SP 10) and Qihai (CV 6) etc. The parallel needling group, in addition to the conventional acupuncture points, received parallel needling at three additional groups of acupoints, i.e. forehead wrinkle group, mid-face group, and corner of the mouth group. Both groups retained needles for 30 min, with one session every other day and a total of three sessions per week, lasting for four weeks. The House-Brackmann (H-B) facial nerve function grading, physical function (FDIP) and social function (FDIS) scores of facial disability index (FDI), TCM syndrome score before and after treatment were compared between the two groups, and the clinical efficacy was assessed.

RESULTS

Compared with before treatment, after treatment, both groups showed improvements in H-B facial nerve function grading (P<0.05), FDIP total scores and sub-item scores were increased (P<0.05), FDIS total scores, sub-item scores, and TCM syndrome scores were decreased (P<0.05). After treatment, the parallel needling group showed the higher FDIP total score and eating sub-item score and lower FDIS total score and insomnia sub-item score compared with those in the conventional acupuncture group (P<0.05). The total effective rate was 90.3% (28/31) in the parallel needling group and 87.1% (27/31) in the conventional acupuncture group, with no statistically significant difference between the two groups (P>0.05).

CONCLUSIONS

The parallel needling technique combined with conventional acupuncture, is as effective as conventional acupuncture alone in treating facial paralysis with qi deficiency and blood stasis. However, the parallel needling technique combined with conventional acupuncture shows advantages in the improvement of food intake and sleep quality.

INDIVIDUAL ARTICLE: Real-World Patient Cases Using Botanical Serum-Containing Corrective Gel as an Adjunct to Aesthetic Facial Laser or Microneedling Radiofrequency (MRF) Treatment

Integrated skin care is defined as the complementary use of topical treatments to nonsurgical facial rejuvenation procedures, such as lasers and radiofrequency microneedling devices, to produce pleasing aesthetic results. Real-world experience from expert dermatologists is invaluable in guiding patient treatment plans, as there are limited clinical trials on the efficacy of integrated skincare regimens. The SkinCeuticals (New York, NY) Phyto Corrective gel (botanical serum-containing corrective gel) contains a lightweight botanical serum that hydrates, calms, and soothes skin. It contains antioxidant and anti-inflammatory ingredients derived from plant and fruit extracts, making it an appealing option for adjunctive treatment of post-procedure erythema and swelling.  J Drugs Dermatol. 2024;23:3(Suppl 2):s3-s14.

Focused ultrasound as an alternative to dry needling for the treatment of tendinopathies: A murine model

Tendinopathies account for 30% of 102 million annual musculoskeletal injuries occurring annually in the United States. Current treatments, like dry needling, induce microdamage to promote healing but produce mixed success rates. Previously, we showed focused ultrasound can noninvasively create microdamage while preserving mechanical properties in ex vivo murine tendons. This present study compared growth factor, histological, and mechanical effects after focused ultrasound or dry needling treatments in an in vivo murine tendon injury model. Partial Achilles tenotomy was performed in 26 rats. One-week postsurgery, tendons were treated with focused ultrasound (1.5 MHz, 1-ms pulses at 10 Hz for 106 s, p+  = 49 MPa, p-  = 19 MPa) or dry needling (30 G needle, 5 fenestrations over 20 s) and survived for 1 additional week. Blood was collected immediately before and after treatment and before euthanasia; plasma was assayed for growth factors. Treated tendons and contralateral controls were harvested for histology or mechanical testing. No differences were found between treatments in release of insulin growth factor 1 and transforming growth factor beta; vascular endothelial growth factor A concentrations were too low for detection. Histologically, focused ultrasound and dry needling tendons displayed localized fibroblast infiltration without collagen proliferation with no detectable differences between treatments. Mechanically, stiffness and percent relaxation of dry needling tendons were lower than controls (p = 0.0041, p = 0.0441, respectively), whereas stiffness and percent relaxation of focused ultrasound tendons were not different from controls. These results suggest focused ultrasound should be studied further to determine how this modality can be leveraged as a therapy for tendinopathies.

Pain (Visual Analogue Scale), disability (Roland-Morris Disability Questionnaire and Oswestry Disability Index), kinesiophobia (Tampa Scale of Kinesiophobia), quality of life and sleep (Short Form 36-item Health Survey and Pittsburgh Sleep Quality Index), isometric endurance of trunk flexor muscles (McQuade test), lumbar mobility in flexion (finger-to-floor distance), and pressure pain threshold (algometer) were assessed at baseline, after 6 weeks, and after 2 months.

RESULTS

ANOVA showed statistically significant differences in group-by-time interaction for most pain pressure thresholds of myofascial trigger points (P < 0.05), for disability (Roland-Morris Disability Questionnaire: F = 6.14, P = 0.016; and Oswestry Disability Index: F = 7.36, P = 0.009), for trunk anteflexion (F = 10.03, P = 0.002) and for habitual sleep efficacy (F = 6.65, P = 0.012), use of hypnotics (F = 4.77, P = 0.033) and total score of quality of sleep (F = 8.23, P = 0.006).

CONCLUSIONS

In comparison to a non-invasive multicomponent intervention, electrical dry needling has more positive effects on disability, pain intensity, kinesiophobia, and reducing patients' sensitivity to myofascial trigger points pressure, at post-treatment and at 2 months.

Effects of neurorehabilitation with and without dry needling technique on muscle thickness, reflex torque, spasticity and functional performance in chronic ischemic stroke patients with spastic upper extremity muscles: a blinded randomized sham-controlled clinical trial

PURPOSE

Evaluation the effects of dry needling on sonographic, biomechanical and functional parameters of spastic upper extremity muscles.

METHODS

Twenty-four patients (35-65 years) with spastic hand were randomly allocated into two equal groups: intervention and sham-controlled groups. The treatment protocol was 12-sessions neurorehabilitation for both groups and 4-sessions dry needling or sham-needling for the intervention group and sham-controlled group respectively on wrist and fingers flexor muscles. The outcomes were muscle thickness, spasticity, upper extremity motor function, hand dexterity and reflex torque which were assessed before, after the 12th session, and after one-month follow-up by a blinded assessor.

RESULTS

The analysis showed that there was a significant reduction in muscle thickness, spasticity and reflex torque and a significant increment in motor function and dexterity in both groups after treatment (p < 0.01). However, these changes were significantly higher in the intervention group (p < 0.01) except for spasticity. Moreover, a significant improvement was seen in all outcomes measured one-month after the end of the treatment in the intervention group (p < 0.01).

CONCLUSIONS

Dry needling plus neurorehabilitation could decrease muscle thickness, spasticity and reflex torque and improve upper-extremity motor performance and dexterity in chronic stroke patients. These changes were lasted one-month after treatment.Trial Registration Number: IRCT20200904048609N1IMPLICATION FOR REHABILITATIONUpper extremity spasticity is one of the stroke consequences which interfere with motor function and dexterity of patient hand in activity of daily livingApplying the dry needling accompanied with neurorehabilitation program in post-stroke patients with muscle spasticity can reduce the muscle thickness, spasticity and reflex torque and improve upper extremity functions.

Treatment of primary restless legs syndrome with Fu's subcutaneous needling: A case report

RATIONALE

Fu's subcutaneous needling (FSN) is a novel acupuncture technique developed based on traditional needling principles that aims to alleviate diseases by improving local muscle conditions and blood supply. FSN have been widely used for the treatment of various diseases. Restless legs syndrome (RLS) is a common central nervous system disorder characterized by intense discomfort in the legs, particularly at night, leading to an urge to move the legs for relief. In this study, we report a case in which FSN was used to treat primary RLS.

PATIENT CONCERNS

A 67-year-old patient complained of nocturnal discomfort in the right leg for over 4 months, the symptoms occurred 2-3 times, with uncontrollable movement impulses in the right leg during the onset, accompanied by a burning sensation, lasting about 2 h, accompanied by anxiety and insomnia. Imaging examinations revealed no spinal stenosis or history of kidney disease, rheumatic disease, diabetes, or Parkinson's disease.

DIAGNOSES

The patient was diagnosed with primary RLS, and the International Restless Legs Syndrome Study Group rating scale (IRLS) score was 26.

INTERVENTIONS

FSN was successfully performed three times per week on different days. No adverse and unanticipated events while the treatment. The total treatment course lasted for six weeks.

OUTCOMES

After the treatment, the patient reported that the recent onset interval was approximately 10 days, each time lasting approximately 15 min. The patient's IRLS score was 5, After a follow-up of 2 months following the end of treatment, the patient reported that the incidence of RLS was approximately one episode within two weeks,each lasting approximately 10 min.

LESSONS

FSN significantly improved leg discomfort and desire for leg movement in patients with RLS. FSN may exert its therapeutic effects by influencing connective and muscular tissues, thereby improving the condition of the central nervous system and the local blood supply in the legs. However, due to the limitation of a single clinical observation case, a randomized clinical trial with a sufficient follow-up time is needed.

Histological evaluation of monopolar and bipolar radiofrequency microneedling treatment in a porcine model

BACKGROUND AND OBJECTIVE

Fractional radiofrequency microneedling (FRM) is widely used as an option for skin rejuvenation, however there is a lack of histological evidence for the various energy delivery systems available. The objective was to assess thermal denaturation of tissue and the wound healing response in monopolar mode versus bipolar mode. Histological analysis was performed to demonstrate the efficacy of automatic impedance feedback system in monopolar mode.

STUDY DESIGN AND METHODS

In this study, the acute thermal effects caused by monopolar FRM treatment to the dorsal skin of pigs were assessed histologically by hematoxylin & eosin (H&E) staining. Then, one session of either monopolar or bipolar FRM was used to treat one or the other side of the pig using varying power levels and pulse widths. The acute and chronic tissue reactions were assessed using H&E, immunofluorescence, and western blot analysis at 0, 14, 30, and 90 days after treatment. The efficacy of the impedance feedback system was also monitored histologically.

RESULTS

High-energy FRM treatment produced tissue loss and necrosis. The power level and pulse duration significantly affected the coagulation amount. Histopathology at 0, 14, 30, and 90 days showed that the skin tissue reaction was more pronounced for bipolar compared to monopolar FRM. Immunofluorescence showed the expression of TGF-β, Ki67, MMP3, and elastin increased dramatically with both modes, but were higher in the bipolar FRM treated side. The automatic impedance feedback system could effectively adjust the output energy.

CONCLUSIONS

We found that bipolar FRM produced greater thermal effects, more collagen coagulation, and more pronounced molecular changes compared with monopolar mode in a porcine animal model.

Elastography findings in acne scar patients who were treated with microneedling

BACKGROUND

Acne scar (AS) is a frequent sequela in patients with acne. In addition to advanced treatment methods, microneedling (MN) is still used as an effective option in the treatment of AS. However, similar to most diseases in dermatology, there is no objective tool to determine the severity of AS and to evaluate the treatment outcome.

OBJECTIVES

In the current study, we aimed to evaluate skin elasticity in AS patients who have undergone MN therapy. Furthermore, other purposes were to determine the relationships between the history of isotretinoin use, demographic data, and changes in skin elasticity.

METHODS

In order to evaluate the skin elasticity of 20 patients with AS, shear wave elastography (SWE) was performed before and after MN treatment. The physician's clinical assessment was evaluated with quantitative AS severity scale. In order to show that SWE is a consistent method, three repeated measurements were performed on 24 healthy participants.

RESULTS

A significant increase was found between the shear-wave velocity (SWV) values that were measured baseline and after treatment in the patient group (P = 0.033). In the control group, there was no significant difference between the three repeated measurements (P > 0.05). A statistically significant decrease was also detected in the AS severity scores (P < 0.005).

CONCLUSIONS

In AS patients who underwent MN treatment, a significant increase was found in skin elasticity compared to the baseline. We argued that SWE is a method that can be useful to evaluate skin elasticity before and after similar cosmetic procedures and dermatological diseases.

Acute Effects of the Dry Needling Session on Gastrocnemius Muscle Biomechanical Properties, and Perfusion with Latent Trigger Points - A Single-Blind Randomized Controlled Trial in Mixed Martial Arts Athletes

The study aimed to evaluate the immediate effects of a dry needling (DN) therapy session on biomechanical properties, muscle power, perfusion, and pressure pain threshold of the gastrocnemius muscle with latent trigger points. Twenty mixed martial arts athletes (MMA) were randomly divided into two groups: experimental (eDN, n = 10) and sham (qDN, n = 10) to undergo one session of DN either with a real or a qazi needle. The measurements were taken at rest, 1-5 minutes after the DN (Post1-5min) and 24h after the DN (Post24h). DN significantly increased the muscle perfusion (Post1-5min and Post24h, p < 0.001), reduced its tone (Post1-5min and Post24h, p < 0.001) and stiffness (Post1-5min, p < 0.05; Post24 h, p < 0.001), and improved its elasticity (Post1-5min and Post24h, p < 0.001). DN also caused a significant increase in pressure pain threshold (Post1-5min, p < 0.001; Post24h, p < 0.05) and in muscle power (Post24h, p < 0.01). The DN session increased the blood perfusion and improved the biomechanical properties of the gastrocnemius muscle, which led to improved muscle power. The DN also had an analgesic effect. These effects were maintained at 24 h, which suggests that DN could facilitate muscle recovery in a post-exercise period of MMA athletes.

Laser Speckle Contrast Imaging Guides Needling Treatment of Vascular Complications from Dermal Fillers

BACKGROUND

Although laser Doppler imaging (LDI) accurately delineates a hypoperfused area to help target hyaluronidase treatment, laser speckle contrast imaging (LSCI) is more appropriate for assessing microvascular hemodynamics and has greater reproducibility than LDI. This study investigated the use of LSCI in the evaluation and treatment of six patients who developed vascular complications after facial dermal filler injections.

METHODS

The areas of vascular occlusion were accurately defined in real time by LSCI and were more precise than visual inspections or photographic evidence for guiding needling and hyaluronidase treatment.

RESULTS

All patients had achieved satisfactory outcomes as early as Day 2 of treatment and no procedure-related complications were reported after a median follow-up of 9.5 (7-37) days.

CONCLUSION

LSCI accurately and noninvasively delineated vascular occlusions in real time among patients experiencing complications of facial dermal filler injections. Moreover, LSCI was more accurate than visual and photographic evaluations. Clinicians can use LSCI to reliably follow-up therapeutic outcomes after salvage interventions for vascular occlusions.

A simple drug-delivery microneedling technique modality successfully improves linear atrophic scars

BACKGROUND

Atrophic scars are white, dermal depressions, caused by the destruction of collagen fibers and decrease in epidermal cells, following inflammation after different types of trauma. They lead to significant physical, aesthetic and psychological barriers and their treatment remain a therapeutic challenge for dermatologists. Microneedling has been shown to improve scars by stimulating angiogenesis and neocolagenesis and the combination of anti-fibrotic drugs could potentialize the results.

METHODS

We present 8 cases of patients with linear scars, successfully treated with two sessions of a new Microneedling technique, using a tattoo machine, associated with drug delivery of 5-FU.

RESULTS

A marked improvement in scar pigmentation and texture were noted by patients and doctors, 6 months following the sessions of MMP and drug delivery with 5-FU, in different body sites. We also showed that the assessment scores of at least one of the professionals with those of the patient had significant correlations with each other, which shows consistency between the qualitative assessment instruments. We also showed that the cause of the injury can influence joint assessment scores (physicians plus patient) or those exclusive to professionals trained for the assessments, generating evidence that the cause of the injury can influence the treatment outcome itself.

CONCLUSIONS

We present an inexpensive and promising approach that can be easily done as an in-office procedure. Larger, multicenter studies are needed to validate this technique among the first line therapies for acne scar treatment.

YIN Kejing's experience in treatment of cyclomastopathy by the accompanied needling at Tianchi (PC 1)

The paper introduces professor YIN Kejing's clinical experience in treatment of cyclomastopathy. In pathogenesis, cyclomastopathy is relevant with dysfunction of the thoroughfare vessel and the conception vessel, the stagnation of blood and phlegm and the stagnation of liver qi. The principle of treatment prefers to unblocking the circulation of qi and blood and adjusting the balance between yin and yang. In diagnosis, the unique meridian palpation is adopted. Regarding the treatment of cyclomastopathy, the accompanied needling at Tianchi (PC 1) is recommended in combination with the external application of herbal medicines, presenting the specific characteristics of traditional Chinese medicine.

Fast needling combined with occupational therapy for hand dysfunction of spastic cerebral palsy : a randomized controlled trial

OBJECTIVES

To compare the clinical effect of fast needling (without needle retaining), needle retaining acupuncture combined with occupational therapy and simple occupational therapy for hand dysfunction of spastic cerebral palsy in children.

METHODS

A total of 75 children with spastic cerebral palsy were randomly divided into an occupational therapy group (25 cases), a fast needling group (25 cases, 1 case dropped out) and a needle retaining group (25 cases, 1 case dropped out). The patients in the occupational therapy group were only treated with occupational therapy for 20 min each time. The patients in the fast needling group were treated with acupuncture (without needle retaining) combined with occupational therapy, and the needle retaining group was treated with acupuncture (needle retaining) combined with occupational therapy, and acupuncture was taken at Hegu (LI 4), Houxi (SI 3), Yuji (LU 10), Waiguan (SJ 5), Jianyu (LI 15) and so on. The needles were retained for 30 min in patients of the needle retaining group. All the above treatments were performed once a day, 5 times a week for 12 weeks. The scores of fine motor function measure (FMFM) and Peabody developmental motor scale 2 (PDMS-2) were observed in patients of the three groups before and after treatment, and the safety of the fast needling group and the needle retaining group was compared.

RESULTS

After treatment, the scores of FMFM and PDMS-2 in patients of the three groups were higher than those before treatment (P<0.01), and the scores of FMFM and PDMS-2 in the fast needling group and the needle retaining group were higher than those in the occupational therapy group (P<0.05, P<0.01). The incidence of acupuncture abnormalities in the fast needling group was 0.3% (5/1 440), which was lower than 1.4% (20/1 440) in the needle retaining group (P<0.05).

CONCLUSIONS

Acupuncture combined with occupational therapy has better clinical effect than occupational therapy alone in improving hand dysfunction in children with spastic cerebral palsy, and there is no statistical difference in effect between fast needling acupuncture and needle retaining acupuncture, but fast needling has better safety than needle retaining acupuncture.

Periocular non-tuberculous mycobacterial infection after autologous fat transfer with micro-needling and fractional radiofrequency skin resurfacing

A 59-year-old woman with prior bilateral lower eyelid autologous fat transfer, subdermal micro-needling and fractional radiofrequency skin resurfacing presented with delayed left-sided preseptal cellulitis with small multinodular abscesses unresponsive to oral outpatient antibiotic regimens and inpatient intravenous antibiotics. Wound culture revealed Mycobacterium chelonae infection treated successfully with a 4-month regimen of clarithromycin and tedizolid without recurrence. This case highlights (1) the need for vigilance and a broad differential in delayed post-operative wound infections including non-tuberculous mycobacterial infections, (2) resolution of infection without recurrence on clarithromycin and novel tedizolid oral antibiotic therapy, and (3) that caution should be exercised when performing combination autologous fat transfers with subdermal micro-needling procedures as the breakdown in skin integrity may potentiate infection.

Comparing dry needling or local acupuncture to various wet needling injection types for musculoskeletal pain and disability. A systematic review of randomized clinical trials

PURPOSE

Systematically evaluate the comparative effectiveness of dry needling (DN) or local acupuncture to various types of wet needling (WN) for musculoskeletal pain disorders (MPD).

METHODS

Seven databases (PubMed, PEDro, SPORTDiscus, CINAHL, Scopus, Embase, and Cochrane Central Register of Controlled Trials) were searched following PROSPERO registration. Randomized clinical trials were included if they compared DN or local acupuncture with WN for MPD. Primary outcomes were pain and/or disability. The Revised Cochrane Collaboration tool (RoB 2.0) assessed the risk of bias.

RESULTS

Twenty-six studies were selected. Wet Needling types included cortisone (CSI) (N = 5), platelet-rich plasma (PRP) (N = 6), Botox (BoT) (N = 3), and local anesthetic injection (LAI) (N = 12). Evidence was rated as low to moderate quality. Results indicate DN produces similar effects to CSI in the short-medium term and superior outcomes in the long term. In addition, DN produces similar outcomes compared to PRP in the short and long term and similar outcomes as BoT in the short and medium term; however, LAI produces better pain outcomes in the short term.

CONCLUSION

Evidence suggests the effectiveness of DN to WN injections is variable depending on the injection type, outcome time frame, and diagnosis. In addition, adverse event data were similar but inconsistently reported. PROSPERO Registration: 2019 CRD42019131826Implications for rehabilitationDry needling produces similar effects for pain and disability in the short and medium term compared to cortisone, Botox, and platelet-rich plasma injections. Local anesthetic injection may be more effective at reducing short-term pain.Long-term effects on pain and disability are similar between dry needling and platelet-rich plasma injections, but dry needling may produce better long-term outcomes than cortisone injections.The available adverse event data is similar between dry and wet needling.The conclusions from this study may be beneficial for patients and clinicians for considering risk and cost benefit analyses.

Immediate effects of superficial dry needling of the trigeminal nerve innervation field for participants with cervicogenic headache. A randomized controlled trial

BACKGROUND

Cervicogenic headache (CGH) is a common condition with a neuroanatomical basis involving the trigeminal nerve. Dry needling (DN) is a safe and effective treatment for CGH but most studies involve deep DN to cervical musculature.

OBJECTIVE

The aim of this study was to investigate immediate effects of superficial DN of the trigeminal nerve innervation field on numeric pain rating scale (NPRS), flexion-rotation test (FRT), cervical range of motion (AROM), and pain-pressure threshold (PPT) of right (R) and left (L) supraorbital (SO), and right (R) and left (L) greater occipital (GO) nerves in participants with CGH.

METHODS

A parallel controlled randomized design involving 30 participants with CGH received either superficial DN (N = 17) or sham DN (N = 13). Participants and outcome assessors were blind to group assignment. Wilcoxon signed rank analyzed within-group effects and Mann-Whitney U analyzed between-group.

RESULTS

Statistically significant between-group differences were observed for NPRS (P < .001) and AROM (P < .006) favoring DN and were clinically meaningful. Right and left Flexion rotation tests (FRT) outcomes were non-significant (P = .137) but clinically meaningful. No differences were observed for PPT over: R SO (P = .187); L SO (P = .052); R GO (P = .187); or L GO (P = .052). Between-group effect sizes across variables were moderate to large (0.53-1.4) but confidence intervals were wide.

CONCLUSION

Superficial DN targeting the innervation field of the trigeminal nerve improves clinical outcomes in patients with CGH. Only the immediate effects were analyzed and the sample size was small. Larger, longer-term assessments are needed comparing superficial DN of the trigeminal innervation field and other conservative interventions for CGH.

The Effects of Dry Needling on Hamstring Range of Motion: A Critically Appraised Topic

CLINICAL SCENARIO

Hamstring range of motion (ROM) and the influence it has on injury risk is among great discussion in the literature. Hamstring injury may result from hamstring tightness, poor flexibility, or decreased ROM, and many argue that this can be prevented through various intervention strategies. In active populations, risk of further injury, pain, and complications throughout the kinetic chain can occur if minimal hamstring ROM is left untreated. One therapeutic intervention that has been applied to varying parts of the body to help improve function while relieving pain is dry needling (DN). This intervention includes the application of needles to structures to induce responses that might benefit healing and overall stimulation of a neurological response. In this review, the intent is to identify evidence and the effects of DN on hamstring ROM.

CLINICAL QUESTION

What are the effects of DN on hamstring ROM?

SUMMARY OF KEY FINDINGS

Among total 11 articles, 1 single-blinded randomized controlled trial and 2 double-blinded randomized controlled trials were included in this critically appraised topic. All 3 articles had inconclusive evidence to isolate the application of the DN intervention. There was insufficient evidence to identify if DN independently improved hamstring ROM; however, in combination with interventions such as exercise and stretch plans, there were improvements on ROM.

CLINICAL BOTTOM LINE

DN does not significantly increase or decrease the ROM of the hamstrings. When combined with exercise and stretch plans, DN could increase ROM.

STRENGTH OF RECOMMENDATION

The grade of B is recommended by the Strength of Recommendation Taxonomy for inconsistent or limited-quality patient-oriented evidence.

Dry needling, trigger point electroacupuncture and motor point electroacupuncture for the treatment of myofascial pain syndrome involving the trapezius: a randomised clinical trial

OBJECTIVE

The objective of this study was to compare trigger point (TrP) dry needling, TrP electroacupuncture and motor point electroacupuncture of the trapezius muscle for the treatment of myofascial pain syndrome (MPS).

METHODS

This randomised clinical trial included 90 patients divided into three groups. Group 1 was treated with dry needling of TrPs, group 2 with intramuscular electrical stimulation of TrPs, and group 3 with electroacupuncture of motor points and/or the spinal accessory nerve. Each group received seven treatment sessions. The outcomes were the pain score measured by visual analogue scale (VAS) and quality of life evaluated by the 12-item short form (SF-12) health questionnaire. We compared the pain outcome over serial time points using growth curve analysis methods.

RESULTS

Participants in the three groups experienced significant improvements in pain scores over time. The average pain level of participants in group 3 across the repeated assessments was 0.98 units lower than in group 1 (mean difference (95% confidence interval (CI) = 1.74-0.23)), p = 0.012). There were no significant differences in pain scores between participants in groups 1 and 2, and there were no significant differences in quality of life across the three groups at the end of the treatment period.

CONCLUSION

Our results provide evidence that electrical stimulation of motor points and/or of the spinal accessory nerve may be superior in terms of pain relief (but not quality of life) to dry needling and possibly electrical stimulation of trigger points for the management of MPS involving the trapezius.

Dry needling perceptions and experiences: A survey of Australian physiotherapists

BACKGROUND

There is a lack of information on the use of dry needling in Australian physiotherapy practice.

OBJECTIVES

Our primary aim was to enhance the understanding of why Australian physiotherapists use dry needling in clinical practice. The secondary aim was to explore Australian physiotherapists experiences with adverse events caused by dry needling.

DESIGN

Cross-sectional online survey.

METHOD

We developed a survey and disseminated it through email to physiotherapists from all states and territories in Australia. Participant demographics and responses were reported as frequencies and percentages.

RESULTS/FINDINGS

We invited 1006 Australian physiotherapists, of which 232 (23%) viewed the online survey and 203 (20%) consented to participate, of which nearly all completed the survey (n = 198, 98%). Most respondents worked in private practice (n = 164, 83%), with 127 (64%) reporting using dry needling as an intervention within the previous 12 months. Physiotherapists typically used dry needling to decrease pain intensity (n = 105, 85%) and reduce muscle tension (n = 100, 81%). Reports of minor adverse events were common and included discomfort during the treatment (n = 77, 62%) and bruising (n = 69, 56%). Some respondents reported experiencing major adverse events including prolonged aggravation of symptoms (n = 10, 8%) and syncope (n = 16, 13%).

CONCLUSIONS

We found that many Australian physiotherapists in private practice use dry needling, usually to decrease pain intensity and muscle tension. Minor adverse events were experienced by more than half the respondents and between 8 and 13% of the Australian physiotherapists surveyed reported experiencing a major adverse event due to dry needling.

Comparative evaluation of microneedling vs injectable platelet-rich fibrin in thin periodontal phenotype: a split-mouth clinical randomized controlled trial

OBJECTIVES

Microneedling and injectable platelet-rich fibrin (i-PRF) have been proposed as relatively less invasive alternatives to surgical procedures for augmentation of thin periodontal phenotype. The present study was conducted to evaluate the effect of microneedling and i-PRF alone on gingival thickness in thin periodontal phenotype individuals.

METHOD AND MATERIALS

Systemically healthy individuals with thin periodontal phenotype in mandibular anterior teeth (n = 21) were treated with microneedling on one side and i-PRF on the contralateral side. Assessment of gingival thickness, keratinized tissue width, and periodontal parameters was done at baseline, and at 1, 3, and 6 months.

RESULTS

In intergroup comparison, a statistically significant increase in gingival thickness was observed with microneedling as compared to i-PRF at 6 months (P < .02). Intragroup comparison from baseline to 6 months showed a statistically significant increase in gingival thickness within both the groups: microneedling from 0.78 ± 0.12 mm to 1.00 ± 0.14 mm (P < .000), and i-PRF from 0.77 ± 0.10 mm to 0.93 ± 0.12 mm (P < .000). Intragroup comparison showed a statistically significant increase in keratinized tissue width in the microneedling group (P < .000). A statistically significant decrease in periodontal parameters was observed on intragroup comparison (P < .000).

CONCLUSION

Considering the higher gain in gingival thickness and the added advantage of eliminating need for autologous blood withdrawal, microneedling is potentially better than i-PRF for phenotype modification in thin periodontal phenotype individuals.

Acupuncture and dry needling for physical therapy of scar: a systematic review

BACKGROUND

There is a continuing interest in finding effective methods for scar treatment. Dry needling is gaining popularity in physiotherapy and is defined by Western medicine as a type of acupuncture. The terms acupuncture and dry needling have been used interchangeably so we have focused on the efficacy of dry needling or acupuncture in scar treatment.

OBJECTIVE

The aim of this systematic review was to determine the usefulness of dry needling or local acupuncture for scar treatment. In our search process, we used the terms 'acupuncture,' 'needling,' or 'dry needling' to identify all relevant scientific papers. We have focused on the practical aspects of local management of different scar types with dry needling or acupuncture.

SEARCH STRATEGY

The search strategy included different combinations of the following keywords: 'scar', 'keloid', 'dry needling', 'needling', 'acupuncture', 'treatment', 'physical therapy'. This systematic review was conducted in accordance with PRISMA guidelines. MEDLINE (PubMed, EBSCOHost and Ovid), EMBASE (Elsevier), and Web of Science databases were searched for relevant publications from inception through October 2023.

INCLUSION CRITERIA

The studies that investigated the effectiveness of dry needling or acupuncture for scar treatment were included.

DATA EXTRACTION AND ANALYSIS

The main extraction data items were: the needling technique; needle: diameter, length; needling locations; manual needling manipulation; number of sessions; settings; outcomes and results.

RESULTS

As a result of a comprehensive search, 11 manuscripts were included in the systematic review, of which eight were case reports, two were randomized trials and one study concerned case series. Two case reports scored 2-4 out of 8 points on the JBI checklist, five studies scored 5-7, and one study scored 8 points. The methodological quality of the two clinical trials was rated as good or fair on the PEDro scale. The case series study scored 7 of 10 points on the JBI checklist. A meta-analysis was not possible as only two randomized trials, eight case reports, and one case series were eligible for review; also, scar assessment scales and pain severity scales were highly heterogeneous.

CONCLUSIONS

The studies differed regarding the delivery of dry needling or local acupuncture for scar treatment. Differences included treatment frequency, duration, number of treatments, selection of needle insertion sites, number of needles used, angle of needle placement, and use of manual needling manipulation.

Alternating Treatment With Nonablative Fractional Laser and Radiofrequency Microneedling for the Treatment of Acne Scars: A Prospective, Randomized, Split-Face Study

BACKGROUND

Acne scarring is an unfortunate sequela affecting up to 95% of patients with acne and carries profound psychosocial impact. Both nonablative fractional lasers (NAFL) and microneedling with radiofrequency (MNRF) have demonstrated comparable efficacy in the treatment of atrophic acne scars.

OBJECTIVE

To determine whether alternating NAFL and MNRF is superior to NAFL alone in the treatment of atrophic acne scars.

METHODS AND MATERIALS

This was a prospective, single-center, double-blinded, split-face clinical trial. Twenty patients with atrophic acne scars who had their facial halves randomized to receive either NAFL alone or NAFL alternating with MNRF. Patients received 4 total treatments at 4-week intervals.

RESULTS

Ninety days after the final treatment, both facial halves demonstrated a significant improvement in the mean global échelle d'évaluation clinique des cicatrices d'acné (ECCA) score from baseline ( p < .001 for both halves). The average percentage improvement at the final end point was 20% to 30% from baseline. No significant difference was noted between facial halves for mean global ECCA score or percentage improvement at any time point.

CONCLUSION

Although both NAFL and MNRF are safe and effective in the treatment of atrophic acne scars, alternating NAFL and MNRF does not seem to be superior to NAFL alone.

Lumbopelvic manipulation alone versus combined with dry needling in physically active patients with patellofemoral pain syndrome: A randomized clinical trial

INTRODUCTION

Patellofemoral pain syndrome (PFPS) is prevalent in physically active people. The multifactorial nature of PFPS necessitates multimodal treatment for this condition. The present study aimed to compare the efficacy of lumbopelvic manipulation alone versus manipulation plus dry needling in physically active patients with PFPS.

METHOD

Thirty patients (18 women and 12 men) with a diagnosis of PFPS entered this randomized controlled clinical trial and were divided into two groups: lumbopelvic manipulation alone or lumbopelvic manipulation plus dry needling. The interventions were applied for 3 sessions every other day. Dry needling was performed on the quadratus lumborum and gluteus medius muscles. Pain intensity, Kujala score and side-plank time were recorded at baseline, post-intervention and 1 month after the intervention.

RESULTS

The results of Friedman's test showed statistically significant differences in pain and function in participants during the study period, and post hoc tests revealed differences between the two groups in behavior of the marginal means (p < 0.001).

CONCLUSION

The use of lumbopelvic manipulation plus dry needling in the quadratus lumborum and gluteus medius muscles may be more effective than manipulation alone in alleviating pain and promoting function in physically active patients with PFPS.

Could dry needling change the kinematics of gait in individuals with piriformis muscle syndromes? Secondary analysis of a randomized controlled trial

INTRODUCTION

Piriformis muscle syndrome (PMS) is a condition that can lead to symptoms including gluteal pain, local tenderness, and limitation of hip joint motion in daily activities, and it may have a major impact on some daily functions such as gait. We proposed that dry needling (DN) can improve the gait of individuals with PMS.

METHODS

Thirty-two individuals with PMS were assigned equally and randomly to the treatment group or the wait-list control group. Subjects in the treatment group received three sessions of DN of the piriformis muscle. All participants in both groups were educated to correct their lifestyles. The outcome measures were the gait-related parameters (walking speed, peak hip flexion, peak hip extension, time to peak internal and external hip rotation, and knee sagittal range of motion), which were evaluated at baseline and after treatment. To compare different outcomes, analysis of covariance (ANCOVA) was used, with baseline as the covariance and groups as a factor.

RESULT

After DN sessions, peak hip extension during gait showed a statistically significant difference [adjusted MD 1.9 (3.7-0.08), p < 0.05, d = 0.56 (0.1-1.28)] in favor of the DN group. Peak hip flexion, on the other hand, exhibited a marginal statistically significant difference [adjusted MD -3.2 (-6.51 to 0.01), p = 0.053, d = 0.44 (1.16 to -0.02)] compared to the control group.

CONCLUSION

The findings suggest that participants in DN showed significantly greater peak extension angle of the hip during walking in individuals with PMS than in the control group.

COMPARISON THE EFFICACY OF DRY NEEDLING AND ISCHEMIC COMPRESSION METHODS IN MIYOFASCIAL PAIN SYNDROME: A RANDOMIZED TRIAL

Myofascial pain syndrome (MPS) is the most common in the musculoskeletal disease. Dry needling techniques and ischemic compression are the most common applications. We aimed to compare the efficacy of dry needling and ischemic compression methods on pain, cervical range of motion and disability in myofascial pain syndrome. This is a randomized, controlled study. 98 patients with MPS were randomly assigned into three groups. Group1 received dry needling (n=33), group 2 (n=33) received ischemic compression and group 3 (n=32) received combined with dry needling and ischemic compression inventions. Additionally, all patients were given neck exercise programs including isotonic, isometric, and stretching. The severity of the pain was measured by visual analog scale (VAS). The pressure pain threshold (PPT) and cervical range of motion (ROM) were also recorded. Disability was assessed by the Neck Pain Disability Scale. All assessments were performed before the treatment and one month and three months after the treatment. There were statistically significant improvements in VAS, PPT, cervical ROM, and disability scores after one and three months in all groups compared to pre-treatment results (p<0.05). After three months of follow-up, statistically significant differences were observed in all parameters between the groups (p<0.05) except cervical ROM (p>0.05). Myofascial pain syndrome in patients with ischemic compression and dry needling effective treatment methods are shown separately in our study to be more effective when used together.

The efficacy and safety of microneedling with topical tranexamic acid for melasma treatment: A systematic review and meta-analysis

OBJECTIVE

Microneedling with topical tranexamic acid (TXA) is a novel treatment option for melasma; however, the efficacy and safety of this combined administration therapy is in controversial. This study is conducted to address this issue of this technique in melasma.

METHODS

An extensive literature review was performed to identify relevant trials, including randomized split-face studies, randomized controlled trials and prospective non-randomized split-face studies, comparing microneedling plus topical TXA to routine treatments or placebo. The primary outcomes were changes of the Melasma Area Severity Index (MASI)/modified MASI (mMASI)/hemi MASI between before and after treatment, as well as the changes between a particular treatment and microneedling plus TXA. The mean differences (MDs) and 95% confidence intervals (CIs) were calculated for the reduction of melasma severity scores from baseline to each time point. In contrast, the standard mean differences (SMDs) and 95% CIs were calculated for the differences in reduction in melasma severity scores between the experimental and control groups at each time point.

RESULTS

A total of 16 trials were included in the systematic review and data synthesis. The pooled analysis demonstrated that MASI, mMASI, and hemiMASI scores decreased significantly at 4 weeks (MD = 1.85; 95% CI = 1.15-2.54), 8 weeks (MD = 3.28; 95% CI = 2.31-4.24), 12 weeks (MD = 4.73; 95% CI = 2.79-6.50), 16 weeks (MD = 3.18; 95% CI = 1.50-4.85), and 20 weeks (MD = 3.20; 95% CI = 1.95-4.46) after treatment when compared with baseline. The reduction in melasma severity scores of microneedling with TXA group at 4 weeks was more significant than the routine treatment group (SMD = 0.97; 95% CI = 0.09-1.86), while insignificant at 8 weeks (SMD = 1.21; 95% CI = -0.17 to 2.59), 12 weeks (SMD = 0.63; 95% CI = -0.03 to 1.29), 16 weeks (SMD = 0.61; 95% CI = -2.85 to 4.07), or 20 weeks (SMD = 1.04; 95% CI = -1.28 to 3.36).

CONCLUSION

Despite the high heterogeneity across these studies, the current findings indicated that microneedling with topical TXA is an alternative treatment option for melasma treatment; and more well-designed studies are needed to confirm it.

YouTube as a source of information and education on ultrasound- guided dry needling

AIM

This study aims to evaluate the educational quality of videos related to ultrasound guided dry needling (USDN). Material and method: This study was designed as a cross-sectional study. A video-based search was performed on the YouTube online video sharing platform (https://www.youtube.com/) using the English keywords "ultrasound guided dry needling" on May 10, 2023. The first 60 videos were analysed.

RESULT

The first 60 videos were analyzed, and 32 videos that met the inclusion criteria were included in the study. The content of the videos mostly consisted of technical knowledge regarding Ultrasound Guided Dry Needling (USGDN) (56.3%) and information (43.84%). The total mean DISCERN score was 26.9 ± 12.0 (range 17 to 54). The total mean JAMA Score was 2.4 ± 0.7 (range 2 to 4). There was no significant differences between the groups, according to the DISCERN, and JAMAs scores (all p>0.05). The video with the highest DISCERN score belongedto The American Institute of Ultrasound in Medicine (AIUM) channel.

CONCLUSION

There is a significant amount of content available on YouTube regarding USDN; however, unfortunately, most of the existing content is of low quality and carries the risk of misinformation. Healthcare professionals should be aware of the importance of health-related information on YouTubeand strive to provide high-quality, accurate, and up-to-date content.

Treating myofascial pain with dry needling: a systematic review for the best evidence-based practices in low back pain

BACKGROUND

 Myofascial pain syndrome (MPS) is a common source of pain in primary care or pain clinics. There are many different ways to manage and treat MPS, such as physical exercise, trigger points massage, and dry needling.

OBJECTIVE

 The objective of this overview is to highlight and discuss the evidence-based treatment of myofascial pain by dry needling in patients with low back pain.

METHODS

 A systematic review was made based on meta-analysis (MA) and randomized controlled trials (RCTs) related to dry needling treatment for myofascial pain in patients with lumbar pain, published from 2000 to 2023.

RESULTS

 A total of 509 records were identified at first. Seventy were published before 2000, so they were excluded. From the remaining 439 studies, ninety-two were RCTs or MA, of which 86 additional studies were excluded for the following reasons: not related to dry needling treatment (n = 79), not published in English (n = 4), duplicated (n = 1), project protocol (n = 1), and not related to myofascial pain (n = 1). So, this review was based on 4 RCTs and two MA. These studies compared dry needling efficacy to other treatments, such as acupuncture, sham dry needling, laser therapy, physical therapy, local anesthetic injection, ischemic compression, and neuroscience education. Despite outcomes and follow-up period varied between them, they showed that dry needling can decrease post-intervention pain intensity and pain disability.

CONCLUSION

 Dry needling is an effective procedure for the treatment of myofascial pain in patients with acute and chronic low back pain. Further high-quality studies are needed to clarify the long-term outcomes.
