The aim of this study was to determine whether and how real-time feedback of dynamic foot pressure index (DFPI) could be used to correct toe-walking gait in spastic diplegic children with dynamic equinus.
Thirteen spastic diplegic children with dynamic equinus were asked to wear a monitoring device to record their ambulation during daily gait, conventional training gait, and feedback training gait. Parameters based on their DFPI and stride duration were compared among the three test conditions.
The results with feedback training were significantly better for all DFPI parameters in comparison to patients' daily gait and showed significant improvements in DFPI for toe-walking gait and percentage of normal gait in comparison to conventional training methods. Moreover, stride duration under two training gaits was longer than patient's daily gait, but there was no significant difference between the two training gaits.
Although the stride duration for the two training gaits was similar, gait training with real-time feedback of DFPI did produce noticeably superior results by increasing heel-loading impulse of toe-walking gait and percentage of normal gait in comparison to convention training methods. However, its effectiveness was still impacted by the motion limitations of diplegic children. Implications for Rehabilitation The DFPI-based gait training feedback system introduced in this study was shown to be more effective at toe-walking gait rehabilitation training over conventional training methods. The feedback system accomplished superior improvement in correcting toe-walking gait, but its effectiveness in an increasing heel-loading impulse in normal gait was still limited by the motion limitations of diplegic children. Stride duration of normal gait and toe-walking gait was similar under conventional and feedback gait training.
本研究旨在确定动态足压指数（DFPI）的实时反馈是否以及如何用于纠正患有动态马蹄内翻足的痉挛型双侧瘫儿童的足尖行走步态。
13名患有动态马蹄内翻足的痉挛型双侧瘫儿童被要求佩戴监测设备，以记录他们在日常步态、传统训练步态和反馈训练步态中的行走情况。比较三种测试条件下基于DFPI和步幅持续时间的参数。
与患者的日常步态相比，反馈训练在所有DFPI参数方面的结果明显更好，并且与传统训练方法相比，在足尖行走步态的DFPI和正常步态百分比方面有显著改善。此外，两种训练步态下的步幅持续时间均长于患者的日常步态，但两种训练步态之间无显著差异。
尽管两种训练步态的步幅持续时间相似，但与传统训练方法相比，DFPI实时反馈的步态训练通过增加足尖行走步态的足跟加载冲动和正常步态百分比，确实产生了明显更好的结果。然而，其有效性仍受到双侧瘫儿童运动限制的影响。康复意义本研究中引入的基于DFPI的步态训练反馈系统在足尖行走步态康复训练中比传统训练方法更有效。该反馈系统在纠正足尖行走步态方面取得了卓越的改善，但其在增加正常步态中足跟加载冲动方面的有效性仍受到双侧瘫儿童运动限制的制约。在传统步态训练和反馈步态训练下，正常步态和足尖行走步态的步幅持续时间相似。
