Normally, when the patient's functional recovery involves partial weight-bearing aided walking using forearm crutches, it is not possible to control the amount of weight-bearing objectively that the individuals carry out and its progression. This leads to significant errors in accuracy and, consequently, complications and after effects in pathologies. To compensate for this deficiency, we have set out to design and validate a measurement system and a computerized record of the loads exerted on Canadian crutches in aided walking as well as incorporating a mechanism for acoustic and visual biofeedback that will inform the subject if said charges are correct, so that they are able correct their errors and avoid problems in their recovery. We analyzed the validity and reliability of the system through a concordance study with the AMTI OR6-7-2000 force plate, extensively validated previously, while finding a correlation coefficient of 0.99 with a significance (p<0.001). We have designed and developed a measurement system with a computerized record, analysis and wireless graphical display of real-time data, incorporating a mechanism for acoustic and visual biofeedback to measure the loads exerted on forearm crutches during aided walking. The device, called "GCH System 1.0" is a reliable and valid instrument.
通常情况下，当患者的功能恢复涉及使用前臂拐杖部分负重辅助行走时，无法客观控制个体所承受的负重量及其进展。这导致在准确性方面存在重大误差，从而导致病理并发症和后遗症。为了弥补这一不足，我们着手设计并验证了一种测量系统和一种计算机化的记录，用于记录加拿大拐杖在辅助行走中所承受的负荷，并纳入了一种声学和视觉生物反馈机制，如果所述负荷正确，该机制将通知使用者，以便他们能够纠正自己的错误并避免在康复过程中出现问题。我们通过与之前经过广泛验证的 AMTI OR6-7-2000 力板进行一致性研究来分析系统的有效性和可靠性，发现相关系数为 0.99，具有统计学意义（p<0.001）。我们设计并开发了一种带有计算机记录、分析和无线图形实时数据显示的测量系统，该系统纳入了一种声学和视觉生物反馈机制，用于测量辅助行走中前臂拐杖所承受的负荷。该设备称为“GCH 系统 1.0”，是一种可靠且有效的工具。
