The initial trauma of a major amputation and the medical disorders secondary to it are being studied at the Biomechanics Laboratory. Problems that arise from amputation and from the replacement of the limb by a prosthetic device are complex but interrelated, and approaches to study on basic, applied and clinical levels must be integrated. Three studies carried on at the Biomechanics Laboratory are described in this paper. In the field of amputation operations, it is believed that certain osteoplastic and myoplastic techniques, along with protection for nerve stumps and measures to provide optimum circulatory conditions, may restore biological and mechanical function to a greater degree than is possible with present procedures. From studies of the expenditure of energy during locomotion with and without assistive devices and during therapeutic exercise, it was found that crutch-walking is metabolically much more costly in energy for the amputee than walking with the suction-socket prosthesis; through these studies, it will be possible to define criteria for maximum work loads for disabled persons. In dermatological studies, although there are still unsolved problems, successful methods of treatment have been developed for certain bacterial and fungus infections, contact dermatitides and disorders resulting from edema.
生物力学实验室正在研究重大截肢手术的初始创伤及其继发的医学病症。截肢以及用假肢替代肢体所产生的问题复杂但相互关联，必须整合基础、应用和临床层面的研究方法。本文介绍了在生物力学实验室进行的三项研究。在截肢手术领域，人们认为某些骨成形术和肌成形术技术，以及对神经残端的保护和提供最佳循环条件的措施，可能比目前的手术方法在更大程度上恢复生物和机械功能。通过对使用和不使用辅助装置行走以及治疗性锻炼期间能量消耗的研究发现，对于截肢者来说，使用拐杖行走在代谢上比使用吸杯式假肢行走消耗的能量要多得多；通过这些研究，将有可能为残疾人确定最大工作负荷的标准。在皮肤病学研究中，虽然仍有未解决的问题，但已经针对某些细菌和真菌感染、接触性皮炎以及水肿引起的病症开发出了成功的治疗方法。
