烧伤后的功能恢复可能会受到瘢痕收缩和挛缩的严重限制。解释这些问题的机制没有得到很好的描述。用一种新的装置在正常皮肤和增生性烧伤瘢痕中产生表面波。以骨传导速度为指标检测烧伤后骨的生物力学变化。剪切波速度在瘢痕中明显更高，在没有明显瘢痕的损伤组织中略高，证实皮肤硬度增加。正常皮肤各向异性在瘢痕组织中被夸大，而在增生性瘢痕附近的未受伤皮肤中未见。这一结果表明正常组织的重组试图补偿瘢痕收缩。剪切波速度的测量客观地记录了影响热损伤恢复的皮肤特性的变化。使用这种或替代技术可能会增加对烧伤后皮肤功能障碍的理解，提高我们治疗此类患者的能力。
Functional recovery after burn injury can be significantly limited by scar contraction and contracture. Mechanisms to explain these problems are not well described. Surface (shear) waves were generated in normal skin and hypertrophic burn scar with a newly described device. The velocity of propagation was used to examine biomechanical changes after burn injury. Shear wave velocity was markedly higher in scar and slightly higher in injured tissue without obvious scarring, verifying increased skin stiffness. Normal skin anisotrophy was exaggerated in scar tissue and not seen in the uninjured skin adjacent to hypertrophic scar. This result suggests the reorganization of normal tissue attempts to compensate for scar contraction. Measurements of shear wave velocity objectively document changes in skin properties that affect the recovery from thermal injury. Use of this or alternate technologies may increase understanding of postburn skin dysfunction, improving our ability to treat such patients.
