Although Western medical acupuncture (WMA) is commonly practised in the UK, a particular approach called dry needling (DN) is becoming increasingly popular in other countries. The legitimacy of the use of DN by conventional non-physician healthcare professionals is questioned by acupuncturists. This article describes the ongoing debate over the practice of DN between physical therapists and acupuncturists, with a particular emphasis on the USA. DN and acupuncture share many similarities but may differ in certain aspects. Currently, little information is available from the literature regarding the relationship between the two needling techniques. Through reviewing their origins, theory, and practice, we found that DN and acupuncture overlap in terms of needling technique with solid filiform needles as well as some fundamental theories. Both WMA and DN are based on modern biomedical understandings of the human body, although DN arguably represents only one subcategory of WMA. The increasing volume of research into needling therapy explains its growing popularity in the musculoskeletal field including sports medicine. To resolve the debate over DN practice, we call for the establishment of a regulatory body to accredit DN courses and a formal, comprehensive educational component and training for healthcare professionals who are not physicians or acupuncturists. Because of the close relationship between DN and acupuncture, collaboration rather than dispute between acupuncturists and other healthcare professionals should be encouraged with respect to education, research, and practice for the benefit of patients with musculoskeletal conditions who require needling therapy.
Analysis of the proteomic profile of pressure ulcers over time is a critical step in the identification of biomarkers of healing or nonhealing in pressure ulcers. The wound fluid from 32 subjects with 42 pressure ulcers was evaluated over 6 weeks at 15 time points. Samples specific to both the interior and the periphery of the wound bed were collected. Antibody screening arrays, isobaric tags for relative and absolute quantitation with mass spectrometry and multiplexed microarrays were used to characterize wound fluid and results were correlated with clinical outcome. Twenty-one proteins were found to distinguish between healed and chronic wounds and 19 proteins were differentially expressed between the interior and periphery of wounds. Four proteins, pyruvate kinase isozymes M1/M2, profilin-1, Ig lambda-1 chain C regions, and Ig gamma-1 chain C region, were present in lower levels for periphery samples when compared to interior samples and six proteins, keratin, type II cytoskeletal 6A (KRT6A), keratin, type I cytoskeletal 14, S100 calcium binding proteins A7, alpha-1-antitrypsin precursor, hemoglobin subunit alpha, and hemoglobin subunit beta, were present in higher levels in periphery samples when compared with interior samples. S100 calcium binding protein A6, S100 calcium binding protein A7, and soluble receptor for advanced glycation end-products had higher levels in the periphery of chronic wounds vs. the interior in planar arrays. A significant temporal trend was noted for monokine induced by gamma interferon (MIG), synonomous with chemokine (C-X-C motif) ligand 9 (CXCL9), which increased as wounds healed and remained nearly constant for ulcers that were not approaching closure.
The incidence rate of pressure ulcers in the USA ranges from 0.4% to 38% in acute care settings and from 2.2% to 23.9% in long-term care settings, and their treatment costs are in the billions of dollars yearly. The proteome of wound fluid may contain early indicators or biomarkers associated with healing in pressure ulcers that would enable treatment regimes to be optimised for each individual. Wound fluid was collected from the interior and periphery of 19 chronic pressure ulcers at 15 time points during 42 days for an analysis of protein expression. Proteins were fractionated using two-dimensional polyacrylamide gel electrophoresis. A comparison of the spot distributions indicates a biochemical difference between the interior and the periphery of wounds. Pressure ulcers that healed show a greater number of spots for interior and peripheral locations combined over time when compared with wounds that did not heal. Using this technique, protein S100A9 was identified as a potential biomarker of wound healing. The identification of differences within the proteome of healing versus non healing pressure ulcers could have great significance in the use of current treatments, as well as the development of new therapeutic interventions.
This study provided preliminary data on wound healing trajectory and predictors with combined E-stim and conventional care. E-stim seemed to expedite wound healing; however, further research studies are needed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
