A clinical locomotion laboratory has been developed to provide quantitative information in the management of gait disorders. The biomedical engineering development of this system identified two major clinical constraints: (a) the need for instrumentation that would not alter the natural gait of the patient and (b) the need for data-processing techniques that would permit analysis and correlation of the large volume of electromyographic (EMg) and kinematic information. The net result has been a unit that incorporates a multichannel telemetry system to capture the EMG and foot-switch information and a television computer system to handle the kinematic information. Gait studies on children with hemiparesis, muscular dystrophy and cerebral palsy have yielded quantitative EMG and kinematic information on the pathomechanics of ambulation in these disorders. Because the information obtained is quantitative, an accurate measure of improvement (or lack of it) after treatment can be documented. Therefore, the locomotion laboratory may have an important role in the preoperative and postoperative evaluation of children whose abnormal gait may require surgical corrective procedures or rehabilitative treatment including the use of prostheses or orthoses.
一个临床运动实验室已被开发出来，用于在步态障碍的管理中提供定量信息。该系统的生物医学工程开发确定了两个主要的临床限制因素：（a）需要不会改变患者自然步态的仪器，以及（b）需要能够对大量肌电图（EMg）和运动学信息进行分析和关联的数据处理技术。最终成果是一个结合了多通道遥测系统以捕获肌电图和足部开关信息以及电视计算机系统以处理运动学信息的装置。对偏瘫、肌肉萎缩症和脑瘫儿童的步态研究得出了有关这些疾病中步行病理力学的定量肌电图和运动学信息。由于所获得的信息是定量的，因此可以记录治疗后改善（或未改善）的准确情况。因此，运动实验室在术前和术后评估那些异常步态可能需要手术矫正程序或康复治疗（包括使用假肢或矫形器）的儿童方面可能具有重要作用。
