Current Usage of Terminologies Related to Acupotomy: A Literature Research and Standardization Suggestion

Analysis of Research Trends in Ultrasound-Guided Acupuncture and Dry-Needling: A Scoping Review

Background: This study aimed to summarize the current status of research on ultrasound-guided acupuncture and dry-needling treatment and the specific treatment methods applied to patients. Methods: A scoping review was conducted, surveying three English databases (PubMed, Embase, and the Cochrane Library) for studies published up to May 2024. All studies related to ultrasound-guided acupuncture and dry-needling treatment were considered. Literature was selected using selection and exclusion criteria, and extracted and organized using EndNote. Results: A total of 107 eligible studies were included. Among the 107 studies, non-comparative studies accounted for the largest proportion (n = 47, 43.9%), followed by randomized controlled trials (RCTs; n = 41, 38.3%). Diseases of the musculoskeletal system or connective tissue (15 diseases of the musculoskeletal system or connective tissue) accounted for most (n = 48, 55.8%) of the 86 diseases studied, followed by symptoms, signs, or clinical conditions not otherwise classified (n = 17, 19.8%). Conclusions: Ultrasound-guided acupuncture and dry-needling have been actively studied and applied for the treatment of various diseases. However, higher-quality studies are needed for further applications in research and clinical practice.

Effects of Acupotomy on Immobilization-Induced Gastrocnemius Contracture and Fibrosis in Rats via Wnt/β-Catenin Signaling

OBJECTIVE

To determine whether acupotomy ameliorates immobilization-induced muscle contracture and fibrosis via Wnt/β-catenin signaling pathway.

METHODS

Thirty Wistar rats were randomly divided into 5 groups (n=6) by a random number table, including control, immobilization, passive stretching, acupotomy, and acupotomy 3 weeks (3-w) groups. The rat model of gastrocnemius contracture was established by immobilizing the right hind limb in plantar flexion for 4 weeks. Rats in the passive stretching group received passive stretching at gastrocnemius, a daily series of 10 repetitions for 30 s each at 30-s intervals for 10 consecutive days. Rats in the acupotomy and acupotomy 3-w groups received acupotomy once and combined with passive stretching at gastrocnemius a daily series of 10 repetitions for 30 s each at 30-s intervals for 10 consecutive days. Additionally, rats in the acupotomy 3-w group were allowed to walk freely for 3 weeks after 10-day therapy. After treatment, range of motion (ROM), gait analysis [i.e., paw area, stance/swing and maximum ratio of paw area to paw area duration (Max dA/dT)], gastrocnemius wet weight and the ratio of muscle wet weight to body weight (MWW/BW) were tested. Gastrocnemius morphometric and muscle fiber cross-sectional area (CSA) were assessed by hematoxylin-eosin staining. Fibrosis-related mRNA expressions (i.e., Wnt 1, β-catenin, axin-2, α-smooth muscle actin, fibronectin, and types I and III collagen) were measured using real-time quantitative polymerase chain reactions. Wnt 1, β-catenin and fibronectin concentrations were measured by enzyme-linked immunosorbent assay. Types I and III collagen in the perimysium and endomysium were analyzed using immunofluorescence.

RESULTS

Compared with the control group, ROM, gait function, muscle weight, MWW/BW and CSA were significantly decreased in the immobilization group (all P<0.01), while protein levels of types I and III collagen, Wnt 1, β-catenin, fibronectin and mRNA levels of fibrosis-related genes were obviously increased (all P<0.01). Treatment with passive stretching or acupotomy restored ROM and gait function and increased muscle wet weight, MWW/BW and CSA (all P<0.05), while protein expression levels of Wnt 1, β-catenin, fibronectin, types I and III collagen and mRNA levels of fibrosis-related genes were remarkably declined compared with the immobilization group (all P<0.05). Compared with passive stretching group, ROM, gait function, MWW was remarkably restored (all P<0.05), and mRNA levels of fibrosis-related genes as well as protein expression levels of Wnt 1, β-catenin, fibronectin, types I and III collagen in the acupotomy group were obviously decreased (all P<0.05). Compared with the acupotomy group, ROM, paw area, Max dA/dT, and MWW were restored (all P<0.05), and mRNA levels of fibrosis-related genes along with protein levels of Wnt 1, β-catenin, fibronectin, types I and III collagen in the acupotomy 3-w group were decreased (P<0.05).

CONCLUSION

Improvements in motor function, muscle contractures, and muscle fibrosis induced by acupotomy correlates with the inhibition of Wnt/β-catenin signaling pathway.

Effectiveness and Safety of Acupotomy Treatment on Shoulder Pain: 25 Multicenter Retrospective Study

Objective

Shoulder pain is a common complaint in outpatient clinics and can result in an inability to work or perform household activities, leading to significant socioeconomic burden. Acupotomy, as one kind acupuncture that has flat knife-shaped tip, has been widely used for treating shoulder pain. However, despite the widespread use of acupotomy in primary medical institutions, large sample size clinical trials have not sufficiently been performed. In this respect, this multi-center retrospective study aimed to investigate the effectiveness and safety of acupotomy in reducing shoulder pain and disability using data from multi-center primary care clinics.

Methods

This study was conducted in 25 Korean medicine clinics affiliated with the Korean Medical Society of Acupotomology, Republic of Korea, from August 2021 to December 2021. The medical records of patients who visited the clinics complaining of shoulder pain were gathered, and among them were those of patients who underwent acupotomy treatment and those who received acupuncture combined therapy. The Numeric Rating Scale (NRS), SPADI (Shoulder Pain and Disability Index), Range of Motion (ROM) and adverse event were evaluated at each visit. A linear mixed-effects models and paired t-test were used to identify the effectiveness of the treatment.

Results

Overall analysis showed that the NRS score of patients decreased from 4.95 ± 1.97 before treatment to 3.78 ± 2.03 after treatment (n = 332, difference in NRS score, 1.17; 95% CI: 0.96-1.38, t = 10.89 p < 0.001). SPADI score decreased from 19.05 ± 20.44 at baseline before treatment to 12.12 ± 17.26 after the last visit, which was statistically significant (n = 332, mean difference in SPADI score, 6.93; 95% CI: 4.71-9.15, t = 6.150, p < 0.001). No serious adverse event was reported in both groups.

Conclusion

This study showed the effectiveness of acupotomy therapy for shoulder pain, and as the treatment sessions increased, the effect of pain reduction and shoulder function improvement were also increased.

Comparison of the effects of acupotomy and acupuncture on knee osteoarthritis: A systematic review and meta-analysis

BACKGROUND AND PURPOSE

Acupotomy and acupuncture are both treatments for knee osteoarthritis symptoms. However, acupotomy also has the additional anatomical effect of dissecting inflamed tissue. The problem this study aims to address is whether acupotomy is a better treatment than acupuncture in treating knee osteoarthritis.

METHODS

We searched the PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Airiti Library, and Wanfang Data databases from inception to March 2022 for randomized controlled clinical trials (RCTs) comparing the effects of acupotomy and acupuncture in patients with knee osteoarthritis.

RESULTS

In total, we identified 43 RCTs in this meta-analysis. Compared to the acupuncture group, acupotomy had a higher cure rate (odds ratio (OR) 2.94, 95% confidence interval (CI) 2.36 to 3.65), indicating a better improvement in daily activity function. Acupotomy was also more effective in pain relief and knee score improvement. However, some RCTs indicated that adverse events in the acupotomy group were greater than in the acupuncture group (OR 1.23, 95% CI 0.42 to 3.60).

CONCLUSION

Our findings indicated that acupotomy was a more effective treatment for knee osteoarthritis than acupuncture. However, most of the included RCTs had moderate risk of bias, meaning that more high-quality RCTs were needed.

The ultrasound-guided percutaneous release technique for De Quervain's disease using an acupotomy

Background

This study aimed to compare the effectiveness and safety of the percutaneous first extensor compartment performed by acupotomy procedure with or without ultrasonic (US) guidance.

Methods

The percutaneous release was performed with an acupotomy on 40 wrists of cadavers, which was divided into US guidance operation and blind operation. Each arm was dissected and assessed regarding the amount of release and the extent of neurovascular and tendon injury. An analysis of finite biomechanical elements based on wrists specimen data is analyzed to observe the stress of the first extensor tendon compartment. A prospective study observed the pain visual analogue score(VAS) and Patient-Rated Wrist Evaluation (PRWEB) changes after the ultrasound guidance or blind acupotomy treatment in 30 dQD patients.

Results

The success rate in the ultrasound-guided technique was 85%, and the blind technique was 70% in the cadaver study, both techniques without neurovascular injury. There was no statistically significant difference between the two groups in measuring the distance from the incision marks to the blood vessels and nerves (P > 0.05). According to the biomechanical analysis, the tendon friction rubs when the wrist is upright. When the wrist is flexed, the tendon and tendon sheath is stressed in the bone ridges. In this prospective study, both ultrasound guidance and blind acupotomy treatment achieved well improvements in pain and function (P < 0.05), but the results with no statistically significant between groups (P > 0.05).

Conclusion

Both blind and US-guided percutaneous release by acupotomy of the first extensor tendon compartment can get a good result. US-guided techniques can improve the success rate during acupotomy operations, especially for beginners and followers.

Percutaneous Release of the First Extensor Tendon Compartment in De Quervain's Disease by Acupotomy with US-Guidance: A Cadaveric Study

Background

De Quervain's disease is a painful stenosing tenosynovitis of the first dorsal compartment of the hand affecting the tendons of the abductor pollicis longus and extensor pollicis brevis. This study aimed to evaluate the safety and efficacy of percutaneous first extensor compartment releases performed on embalmed cadaveric models by acupotomy operation with or without US guidance.

Methods

Percutaneous release was performed with an acupotomy on 59 wrists of cadavers; 23 wrists were operated with US guidance, and 39 wrists were operated without US guidance. Each arm was dissected and assessed regarding the amount of release as well as the extent of neurovascular and tendon injury. Anatomical structures were also observed in this study.

Results

Twenty cases (87%) were successfully released with ultrasound-assisted techniques, and 27 cases (75%) were successfully released with blind techniques. No neurovascular injury occurred in any arm, regardless of technique. No significant tendon injury was seen in any arm. Although minor surface scratches were visualized in 11 cases, they occurred in 3 cases (13.04%) with ultrasound assistance and in 8 cases (22.22%) with blind techniques. There was no statistically significant difference between the two groups in the measurement of the distance from the incision marks to the blood vessels and nerves. A fibrous septum and bony protrusions were found in the first dorsal compartment, which may be anatomical factors affecting the success of treatment.

Conclusion

Both traditional and US-guided percutaneous release by acupotomy of the first extensor tendon compartment can be performed for all wrists. US-guided techniques can improve the success rate and reduce damage during acupotomy operations.

Acupotomy by ultrasound-guided versus anatomical guidance in knee osteoarthritis: A protocol for systematic review and meta-analysis

BACKGROUND

At present, there is no systematic evaluation on whether ultrasonic-guided acupotomy is more effective compared with anatomical guidance in knee osteoarthritis. We conducted a protocol for systematic review and meta-analysis to provide a method for evaluating the effectiveness and safety of acupotomy by ultrasound-guided technique.

METHODS

An all-round retrieval will be performed in the following electronic journal databases from their inception to October 2022, which comprise PubMed, MEDLINE, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wanfang data, Chinese Scientific Journals Database, and China biomedical literature database. The following key words were used on combination with Boolean operators AND or OR: "acupotomy," "ultrasound," "knee osteoarthritis." Two authors completed the quality assessment using the Cochrane Collaborations risk of bias tool. The meta-analysis was conducted using Review Manager 5.3 software from the Cochrane Collaboration (London, UK).

RESULTS

The findings of this study will be submitted to peer-reviewed journals for publication.

CONCLUSION

This systematic review will provide evidence to judge whether acupotomy by ultrasound-guided technique is effective and safe for knee osteoarthritis.

Safety of acupotomy in a real-world setting: A prospective pilot and feasibility study

OBJECTIVE

Acupotomy is a modern acupuncture method that includes modern surgical methods. Since acupotomy is relatively more invasive than filiform acupuncture treatment, it is important to establish the safety profile of this practice. To justify further large-scale prospective observational studies, this preliminary study was performed to assess the feasibility of the approach and investigate the safety profile and factors potentially associated with adverse events (AEs).

METHODS

This was a prospective pilot study that assessed the feasibility of a large-scale forthcoming safety study on acupotomy treatment in a real-world setting. The feasibility (call response rate, drop-out rate, response rate for each variable and recruitment per month) and safety profile (incidence, type, severity and causality of AEs, and factors potentially associated with AEs) were measured.

RESULTS

A total of 28 participants joined the study from January to May 2018. A follow-up assessment was achieved in 258 (1185 treatment points) out of 261 sessions (1214 treatment points). The response rate via telephone on the day after treatment was 87.3%. There were 8 systemic AEs in all the sessions (8/258; 3.11%) and 27 local AEs on the total points treated (27/1185; 2.28%). Severe AEs did not occur. Total AE and local AE occurrence were associated with blade width and the number of needle stimulations per treatment point.

CONCLUSION

The findings suggest that it could be feasible to analyze the safety of acupotomy in a real-world setting. Moreover, the primary data on some relevant AEs could be determined. We are planning large-scale prospective studies based on these findings.

Acupuncture and Dry Needling for Sports Performance and Recovery

ABSTRACT

Acupuncture and dry needling share many similarities in their proposed mechanisms of action and their sports medicine-related applications. Pain is the most common indication for these needling treatments, but there also are some limited studies on their use for ergogenic purposes. Needling can likely improve muscular strength and power, including increasing jump height, and it also can increase flexibility. In terms of sports recovery, acupuncture can not only be used for pain relief after injury, but also can help with routine recovery, such as in delayed onset muscle soreness. There are numerous case reports of acupuncture and dry needling being used to treat athletes for various diagnoses and conditions, however more high quality studies are needed in order to make more specific evidence-based recommendations. Given the high degree of safety and limited adverse events associated with needling treatments, it can likely be promoted in athletes.

Effectiveness and safety of acupotomy on lumbar spinal stenosis: A pragmatic randomized, controlled, pilot clinical trial: A study protocol

INTRODUCTION

Lumbar spinal stenosis (LSS) is a pathological condition that causes a variety of neurological symptoms due to narrowing of the anatomical structures; usually, conservative treatment is recommended, rather than surgical treatment. Acupotomy combines conventional acupuncture with small scalpels; the procedure can be considered minimally invasive, and has recently received considerable attention in clinical practice. Still, there is a lack of data and randomized controlled trials regarding acupotomy related to LSS. Additional studies are necessary, considering the low methodological quality and small size of the study.

METHODS AND ANALYSIS

This is a pragmatic, pilot, randomized controlled trial. The trial comprises 8 weeks of treatment, with 16 visits and a 4-week follow-up period. Forty participants diagnosed with LSS will be randomly assigned to either the experimental or control groups; both groups will receive acupuncture and interferential current therapy twice a week for 8 weeks, while the experimental group will receive an additional acupotomy intervention once a week for 8 weeks. The primary outcome will be assessed using the visual analog scale; the secondary outcome will be measured by self-rated walking distance, Oswestry Disability Index, and short-form McGill Pain Questionnaire. Measurements will be obtained prior to the start of the clinical trial, 4 weeks after the interventional procedure, 8 weeks after the procedure, and 4 weeks after the end of the interventional procedure. Blood tests and adverse reactions will be performed to ensure safety of the treatments.

CONCLUSION

We expect that this study will provide basic data for future large-scale acupotomy studies regarding LSS.

Acupotomy for Osteoarthritis of the Knee; A Systematic Review and Meta-Analysis

The purpose of this study was to evaluate the effectiveness and safety of acupotomy for the treatment of patients with knee osteoarthritis. There were 9 databases searched to retrieve randomized controlled trials until August 3, 2019 regarding acupotomy versus conventional Western medicine, conventional Western medicine treatment with and without acupotomy, and Korean medicine treatment with and without acupotomy, and meta-analysis was performed. Of 303 potentially relevant studies retrieved, 43 were systematically reviewed. All studies were conducted in China. Effective rate, visual analogue scale, and Western Ontario and McMaster Universities Osteoarthritis index were used as the evaluation scales. The Ashi point was selected most frequently. In all studies, the intervention group was more effective than the control group. Meta-analysis revealed that acupotomy showed statistically significant beneficial results. Although acupotomy had a beneficial effect on knee osteoarthritis, the risk of bias of the included studies was not low. The majority of the results from the evaluation scales used were highly heterogeneous (> 50%) which reduced confidence in the estimation of effect, or had a small sample size. Further clinical research and development is required in the future.

Acupotomy treatment for finger joint contracture after immobilization: Case report

INTRODUCTION

Contractures frequently occur in the finger joints after immobilization. This report describes the effect of acupotomy treatment in patients with joint contracture due to immobilization of the finger joints.

PATIENT CONCERNS AND CLINICAL FINDINGS

Case 1 was of a 39-year-old male patient who had flexion limitation of the left thumb and difficulty in grasping. Case 2 was of a 41-year-old female patient who had flexion limitation of the right index finger and difficulty in typing. Stiffness occurred after tendon repair surgery and cast immobilization in both cases. In Case 1, the patient had limited flexion movement of the first metacarpophalangeal and interphalangeal joints after 5 weeks of immobilization of the left thumb in a cast. In Case 2, the patient had limited flexion movement after 3 weeks of immobilization of the second proximal interphalangeal joint of the left hand in a cast.

DIAGNOSIS, INTERVENTIONS, AND OUTCOMES

We diagnosed both patients with finger joint contracture due to immobilization. Conservative treatment for approximately 4 weeks did not lead to improvement in either patient. Acupotomy is the key treatment for improving movement in Korean Medicine. Therefore, acupotomy was performed, and joint stiffness markedly improved without adverse events. Both patients reported that the daily use of the damaged fingers became comfortable.

CONCLUSION

We found that acupotomy may be effective for finger joint contracture due to improper immobilization. We suggest it as a simple and safe treatment for joint contracture.

Using magnetic resonance imaging to measure the depth of acupotomy points in the lumbar spine: A retrospective study

Background

The acupotomy is an acupuncture device recently used to stimulate lumbar vertebrae such as transverse processes (TPs) and facet joints (FJs). However, there are many organs, nerves, and blood vessels, which can lead to side effects if the needle misses the treatment target. Therefore, information regarding appropriate insertion depths, which is currently lacking, could facilitate its safe use. We retrospectively investigated the depth from the skin to the TP and FJ of the lumbar vertebrae, using magnetic resonance imaging (MRI).

Methods

This retrospective chart review was conducted at a single medical centre in Korea. From 55,129 patient records, 158 subjects were selected. Perpendicular depth from the skin to the left and right TPs and FJs was measured using T1-weighted sagittal plane MRI. Depth differences between the left and right sides were evaluated using the paired t-test and analysis of covariance (body mass index [BMI] as a covariate). The influence of BMI on depth at each location was evaluated by simple linear regression analysis.

Results

The mean age was 43.2 years and mean BMI was 23.6 kg/m². The depth from skin to the TPs or FJs was unaffected by age, sex, or side. Mean depths (cm) were as follows: (TPs) L1 = 4.5, L2 = 4.9, L3 = 5.3, L4 = 5.7, L5 = 5.9; (FJs) L12 = 3.8, L23 = 4.0, L34 = 4.4, L45 = 4.6, L5S1 = 4.6. Depth was highly correlated with BMI at each location.

Conclusion

The depth of TPs and FJs adjusted for BMI can safely and effectively be used for treatment via various invasive interventions, including acupotomy treatment, in the lumbar region.

Efficacy of needle-knife combined with etanercept treatment regarding disease activity and hip joint function in ankylosing spondylitis patients with hip joint involvement: A randomized controlled study

This study aimed to assess the efficacy of needle-knife (NK) combined with etanercept (NKCE) in attenuating pain, inflammation, disease activity, and improving hip joint function in ankylosing spondylitis (AS) patients with hip joint involvement.Totally, 90 patients with active AS involving unilateral hip joint were enrolled and randomly assigned in 1:1:1 ratio to receive NKCE, NK or conventional drugs (control). The ESR, CRP, hip joint pain Visual Analogue Scale (VAS) score, bath ankylosing spondylitis disease activity index (BASDAI), bath ankylosing spondylitis functional index (BASFI), modified Harris hip score (mHHS), and range of motion (ROM) of affected hip joint were assessed at baseline (W0), after 1-week treatment (W1) and after 24-week treatment (W24).ESR and CRP were decreased in NKCE group compared with NK and control groups, while was not attenuated in NK group compared with control group. Regrading pain and disease activity, NKCE group presented a reduction in hip pain VAS score and BASDAI compared with NK and control groups, and NK group showed a decrease in hip pain VAS score and BASDAI compared with control group. Besides, BASFI was lowered in NKCE and NK groups compared with control group, but similar between NKCE and NK groups. mHHS and hip ROM were raised in NKCE and NK groups compared with control group, but similar between NKCE and NK groups.NKCE decreases hip pain, inflammation, disease activity and improves hip joint function in AS patients with hip joint involvement.

Acupotomy for the treatment of lumbar spinal stenosis: A systematic review and meta-analysis

BACKGROUND

Lumbar spinal stenosis (LSS) is caused by neural compression due to narrowing of the lumbar spinal canal or neural foramen. Surgical intervention is a standard treatment for LSS; however, the steep increase in the surgical rate, post-operative complications, and comparatively low long-term satisfaction are considered to be limitations of this surgical approach. Conversely, acupotomy is a minimally invasive technique that combines the effects of conventional acupuncture with micro-incision, which may offer an alternative to surgery for the treatment of LSS. This review was conducted to investigate and critically review the current evidence on the efficacy and safety of acupotomy for LSS.

METHODS

Eleven databases were searched from their respective inception dates to December 28, 2018. Randomized controlled trials (RCTs) comparing acupotomy and wait-list, sham treatment, or active controls were included. The quality of the included studies was assessed using risk-of-bias tool.

RESULTS

Seven RCTs were included in this review and meta-analysis. The methodological quality of the included studies was generally poor. The acupotomy treatment group was associated with significantly lower visual analogue scale scores (range 0∼10) (5 RCTs; mean difference [MD] -1.55, 95% confidence interval [CIs] -2.60 to -0.50; I = 94%) and higher Japanese Orthopedic Association Score (3 RCTs; MD 4.70, 95% CI 3.73 to 5.68; I = 0%) compared to the active control group. In subgroup analysis based on the type of active controls, acupotomy retained significant benefits over lumbar traction and acupuncture, as well as over lumbar traction, spinal decompression, and acupuncture. Safety data were reported in only 1 study, and no adverse events occurred in either the acupotomy or the acupuncture control group.

CONCLUSION

According to current evidence, acupotomy might be beneficial for treating LSS. Acupotomy showed consistent superiority over lumbar traction, but the results were mixed in comparisons with other interventions, such as spinal decompression and acupuncture. However, the findings should be interpreted cautiously, given the poor methodological quality of the included studies, and potential small-study effects. Further larger, high-quality, rigorous RCTs should be conducted on this topic and rigorous reporting of acupotomy procedures and safety data should be encouraged.
