Light and electron microscopy were performed in a study of the effects of electrical stimulation upon the reparative processes in flexor tendons cultured in vitro. After one or two weeks of incubation, the unstimulated control tendons were covered with fibroblastic surface cells, thought to have originated from the epitenon. In contrast, the tendons subjected to electrical stimulation had no proliferation of the epitenon cells in the surface layer. The results indicate that electrical currents of low amperage suppress adhesion-causing synovial proliferation in the epitenon and promote active collagen synthesis in the tenocytes. This suggests the potential value of electrical stimulation in the control of adhesion formation after flexor tendon repair.
在一项关于电刺激对体外培养的屈肌腱修复过程影响的研究中，进行了光镜和电镜检查。孵育一或两周后，未受刺激的对照肌腱被认为起源于腱外膜的成纤维细胞表面细胞所覆盖。相比之下，接受电刺激的肌腱表层腱外膜细胞没有增殖。结果表明，低电流抑制腱外膜中引起粘连的滑膜增殖，并促进腱细胞中活性胶原蛋白的合成。这表明电刺激在屈肌腱修复后控制粘连形成方面具有潜在价值。
