35 unresolved questions extracted from the limitations and future-work sections of 266 Acupuncture Treatment Research Studies papers in our library. Each links back to the study that raised it.

What the literature leaves open

  • However, additional studies are needed to assess the pain conditions experi- enced by breast cancer survivors, including myofascial pain. [11] assessed acupoint stimulation for managing adverse events in patients with breast cancer and found that only three studies assessed postmastec- tomy pain, with inconsistent results.

    Neuroanatomy-Based Acupuncture for Pain after Breast Cancer Surgery: A Novel Therapeutic Approach · 2026 · DOI

  • Conclusions: The findings suggest possible add-on benefits of AAPA when used with conventional post-stroke care, but the current evidence should be interpreted cautiously and is insufficient to support definitive clinical recommendations.

    Acupoint-to-Acupoint Penetrating Acupuncture as an Add-on to Conventional Care for Post-Stroke Spasticity: A Systematic Review and Meta-Analysis · 2026 · DOI

  • While the findings of this study suggest that WNA has potential as an adjunctive therapy for improving symp- toms of postoperative stiff knee at the tibial plateau fracture, its benefit could not be assessed due to the lack of published evidence on the standalone effect of WNA.

    Warm Needle Acupuncture for Postoperative Stiff Knee at Tibial Plateau Fracture: A Narrative Review of Randomized Controlled Trials · 2026 · DOI

  • Objective Acupoint catgut embedding (ACE) shows promise for improving insulin resistance in abdominal obesity, but its comparative efficacy against other interventions remains unclear due to a lack of head-to-head trials.

    Acupoint catgut embedding for improving HOMA-IR in patients with abdominal obesity and insulin resistance: a protocol for systematic review and network meta-analysis · 2026 · DOI

  • This finding indicates that within the conventional treatment framework, EA, as a potentially safe and accessible adjuvant strategy, warrants further investigation.

    Electroacupuncture as an adjunctive therapy for drug-refractory primary open-angle glaucoma: a CARE-compliant case report · 2026 · DOI

  • The etiology of secondary SHS remains unclear; however, it is hypothesized to result from shoulder and wrist damage due to improper upper limb movements during the early stages of stroke, impaired upper limb fluid circulation, and vascular dysfunction due to central nervous system damage (37).

    The clinical effect of manual therapy including Tuina (or Chuna) on post-stroke shoulder hand syndrome–a literature review · 2026 · DOI

  • Direct genetic manipulation tools such as conditional gene knockout and RNA interference targeting PGAM5 and FUNDC1 have not been employed to verify the role of the PGAM5/FUNDC1 axis in electroacupuncture-mediated neuronal apoptosis inhibition. These specific genetic approaches are needed to provide definitive evidence beyond indirect pharmacological inhibition.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • The study only used male animal models to control hormonal variations and did not examine gender differences in response to electroacupuncture after ischemic stroke, despite gender being a known influencing factor for stroke prognosis. Validation of the PGAM5/FUNDC1-dependent mitophagy mechanism in both male and female models is required.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • The research focuses exclusively on neuronal responses in MCAO model-affected regions (striatum and cortex) without investigating how astrocytes and microglia contribute to neuronal autophagy and apoptosis suppression through neuroinflammation regulation and mitochondrial homeostasis maintenance during electroacupuncture treatment.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • The pharmacokinetic characteristics of 3-MA remain uncharacterized, particularly its duration of action and half-life. Since 3-MA effects were not sustained on day 9 post-treatment, pharmacokinetic analyses are needed to determine whether extended dosing intervals or modified administration schedules could maintain long-term autophagy inhibition during electroacupuncture studies.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • The mechanism exploration relies on 3-MA as the primary autophagy inhibitor, which is non-specific and affects multiple pathways including PI3K beyond mitochondrial autophagy. Direct validation methods such as PGAM5 or FUNDC1 gene knockdown or mutation targeting are needed to confirm the PGAM5/FUNDC1-dependent mitophagy pathway in electroacupuncture neuroprotection.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • The study did not include adequate control group settings such as sham acupuncture and simple acupuncture controls alongside the electroacupuncture intervention. The absence of these comparative controls makes it difficult to isolate the specific mechanisms of EA versus placebo or non-electrical acupuncture effects.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • The experimental design lacks systematic comparison of different electroacupuncture parameters including EA frequencies, current intensities, and acupoint combinations. Without controlled comparisons of these treatment variables, it is challenging to determine the optimal EA treatment plan for ischemic stroke.

    Electroacupuncture inhibited neuronal apoptosis through PGAM5/FUNDC1-dependent mitophagy after ischemic stroke · 2026 · DOI

  • Conclusions Manual acupuncture with or without antidepressants may alleviate the severity of MDD, but its clinical benefit for treating MDD is inconclusive.

    A Meta-analysis of Different Acupuncture Modalities Combined With Antidepressants to Reduce Major Depressive Disorder · 2024 · DOI

  • Overall, the results suggest a potential role of acupuncture in improving acute dental pain intraoperatively and postoperatively as well as improving the efficacy of local anesthesia, but the results are limited due to methodological shortcomings emphasizing the necessity for future high-quality research.

    Acupuncture in management of acute dental pain – A systematic review and meta-analysis · 2023 · DOI

  • The purpose of this integrative review of the literature is to synthesize the current evidence and identify gaps in knowledge regarding the effectiveness of acupuncture to treat chemotherapy-induced peripheral neuropathy (CIPN).

  • To our knowledge, few reports have examined the probabilities of improvement, worsening, and stability together with multiple interpretation metrics within a unified framework.

    From Effect Sizes to Clinical Probabilities: An Exploratory Methodological Framework for Evidence Interpretation and Communication · 2026 · DOI

  • First, despite the multicenter design, the present study remains an internally validated retrospective analysis rather than a true external validation study; therefore, the transportability of the model to other regions, institu- tions, and clinical workflows remains to be established.

  • Further investigation of the effect of stimulation duration for both TEAS and TENS is recommended.

  • Findings will add to the limited evidence available regarding the optimal number of sessions of acupuncture in the management of chronic low back pain, as well as being clinically relevant to clinicians, researchers and policy makers.

    Does the dose of Traditional Chinese Medicine acupuncture in addition to usual care affect outcomes for adults with chronic low back pain? Protocol for a randomized controlled feasibility study · 2015 · DOI

  • This systematic review shows that qualitative assessments by three criteria lists focusing on internal validity, gave the same results, and that there is limited evidence for the efficacy of acupuncture in the management of tension-type headache.

    Acupuncture in the management of tension-type headache · 2005 · DOI

  • BACKGROUND: Because the value of popular forms of alternative care for chronic back pain remains uncertain, we compared the effectiveness of acupuncture, therapeutic massage, and self-care education for persistent back pain.
