摘要

The objective of this study was to compare the reliability and validity of the motion parameter values measured by motion detection smart calf sleevess at different walking speeds with the gold standard. Methods: The validity and reproducibility of repeated measurements of eight healthy men walking at three speeds were evaluated using parameters such as stride duration, step duration, stance duration, and swing duration. Results: The reliability of the motion detection smart calf sleeves was tested by comparing the participants' performance at different walking speeds, and the findings indicated that results from normal and fast walking speeds aligned with the golden standard the most. In addition, variation in the double-leg stance duration and swing duration was observed between slow and fast walking speeds. Conclusion: A set of standardised experimental procedures was successfully developed. The researcher gained a firmer grasp on the functions and characteristics of commercially available motion detection smart calf sleeves, which facilitates the promotion of such products to the industry and assists manufacturers in product development. The relevant data can serve as a reference for the formulation of industry specifications for manufacturers developing related products.

本研究旨在探討動作偵測智慧紡織品於不同速度行走時量測的動作參數與效標之信效度比對。方法：本研究邀請8位健康男性，以3種不同速度進行，最後以行走時的步態動作參數進行效度及重覆量測之再現性評估。結果：動作偵測智慧紡織品在人與人間量測結果之信度比對，其結果速度於常速與校標作比較最為一致。而於慢速及快速時於支撐期與擺盪期會產生變異。結論：本研究已成功發展一套標準化實驗流程，其相關研究數據可提供未來廠商發展相關產品之制定產業規範參考。
