Gait analysis is vital from the view of its established capacity as an indicator for neuromuscular disorders. Gait analysis is carried out in order to provide a quantified assessment of human movement which may aid orthopaedic and podiatric fraternity to suggest suitable therapeutic treatment. The proposed study comprises of two wearable non-invasive devices realized using FBG sensors i.e. Knee Angle Measurement Device (KAMD) for dynamic knee angle measurement and Forefoot Load Measurement Device (FLMD) for dynamic measurement of load on the forefoot. In the present study, the assessment of locomotion is illustrated and analyzed utilizing the developed devices without any time synchronization complexity. During locomotion, the swing and the stance phase is analyzed with respect to both knee joint angle and forefoot load which further reveals the complementary nature between them. In addition, FLMD can also be utilized for the evaluation of single and double limb support phases during locomotion. Furthermore, the novel cantilever approach utilized in the FLMD design ensures to acquire the load imparted specifically over the forefoot region which facilitates FLMD to be employed for assessment of other locomotory actions such as landing phase analysis during leaps, climbing stairs, treadmill tests etc. Also, the cantilever approach helps minimize the hysteresis effects on the device.

使用基于光纤光栅传感器的设备评估步态的时空参数

从其作为神经肌肉疾病指标的确定能力来看，步态分析至关重要。进行步态分析是为了提供对人体运动的量化评估，这可能有助于骨科和足病友情建议合适的治疗方法。拟议的研究包括使用FBG传感器实现的两个可穿戴式非侵入性设备，即用于动态膝盖角度测量的膝部角度测量设备（KAMD）和用于动态测量前脚上负载的前脚负荷测量设备（FLMD）。在本研究中，使用开发的设备说明并分析了运动评估，而没有任何时间同步复杂性。在运动中，相对于膝关节角度和前脚负荷分析了挥杆和姿态阶段，这进一步揭示了它们之间的互补性。此外，FLMD还可以用于运动过程中单肢和双肢支持阶段的评估。此外，FLMD设计中采用的新颖悬臂方法可确保获取前脚区域特有的负载，这有助于FLMD用于评估其他机动力，例如跳跃，爬楼梯，跑步机测试等着陆阶段分析。 ，悬臂方法有助于最大程度地减少对设备的磁滞效应。
