糖尿病足溃疡是一种常见的并发症,约占糖尿病患者的15%。超过60%的糖尿病足溃疡是由潜在的神经病引起的。以前对患有足部伤口的糖尿病动物的研究发现,振动平台通过催化上皮化显着加速伤口愈合,促进血管生成,增强肌肉体积。该结果表明有证据表明振动可以加速人类患者的糖尿病性神经性溃疡愈合。然而,据我们所知,很少研究振动对人类患者糖尿病足溃疡愈合的增强作用。因此,在这项工作中,我们对人类受试者进行了一项实验研究,以调查振动疗法是否,作为标准伤口治疗的补充,能加快糖尿病神经性足部溃疡的创面愈合速度。在这项前瞻性实验研究中,80名被诊断为WagnerI-III级糖尿病神经性足溃疡的参与者被随机分配到实验组(n=40)和对照组(n=40)。干预组患者接受标准伤口治疗和振动伤口治疗(VWT),而对照组患者仅恢复标准伤口治疗。结果(p=0.024,α=0.05)显示干预组(25天,95%CI:20.3-29.7)和对照组(33天,95%CI:25.6-40.4),效果大小为r,Cohen\'sd,玻璃的Δ,和对冲,分别,分别为0.810、2.764、2.311和2.772。此外,一氧化氮(NO)水平,伤口闭合面积,干预后伤口愈合评分两组差异有统计学意义(p<0.05),干预组的水平高于对照组。此外,发现NO水平与伤口愈合闭合率之间存在正相关。这些发现表明VWT在治愈率方面增强了糖尿病神经性足溃疡的愈合,伤口闭合面积,愈合评分,和升高的NO水平。考虑到振动干预诱发的患者未发现临床不良反应,VWT可以被视为对现有治疗的补充治疗,以加速DFU的愈合。
Diabetic foot ulcers are a common complication that occurs in approximately 15 percent of patients with diabetes mellitus. Over 60% of diabetic foot ulcers are caused by underlying neuropathy. Former studies on diabetic animals with foot wounds found that vibration platforms significantly accelerate wound healing by catalyzing epithelization, promoting angiogenesis, and enhancing muscle bulk. This result suggests that there is evidence that vibrations may accelerate diabetic neuropathic ulcer healing in human patients. However, to the best of our knowledge, the effect of vibration on the enhancements of diabetic foot ulcer healing in human patients is rarely investigated. Hence, in this work, we conducted an experimental
study with human subjects to investigate whether vibration therapy, as a complement to the standard wound treatment, can accelerate the wound healing rate of diabetic neuropathic foot ulcers. In this prospective experimental
study, 80 participants diagnosed with Wagner grades I−III diabetic neuropathic foot ulcers were randomly distributed to experimental (n = 40) and control groups (n = 40). Patients in the intervention group received standard wound treatment and vibration wound therapy (VWT), whereas patients in the control group retrieved only standard wound treatment. The results (p = 0.024, α = 0.05) show notable differences in the median healing rate between the intervention group (25 days, 95% CI: 20.3−29.7) and control group (33 days, 95% CI: 25.6−40.4), with the effect-size r, Cohen’s d, Glass’s Δ, and Hedges’ g, respectively, being 0.810, 2.764, 2.311, and 2.772. Moreover, the nitric oxide (NO) level, wound closure area, and wound healing score after intervention significantly differed between the two groups (p < 0.05), putting the intervention group on a higher level than the control group. Furthermore, positive associations were found between the NO level and wound healing closure rates. These findings suggested that VWT enhances diabetic neuropathic foot ulcer healing in terms of healing rate, wound closure area, healing score, and elevated NO level. Considering that no clinically adverse effects were found in the patients induced with vibration intervention, VWT can be regarded as a complementary therapy to the existing ones to accelerate the healing of DFUs.
