The Feasibility and Validity of a Wearable Sensor System to Assess the Stability of High-Functioning Lower-Limb Prosthesis Users

This study assessed feasibility and construct validity of a wearable sensor system (APDM Mobility Lab) to measure postural control and gait stability. Materials and Methods Lower-limb prosthesis users (n = 22) and able-bodied controls (n = 24) completed an Instrumented Stand-and-Walk Test (ISAW) while wearing the wearable sensors. Known-groups analysis (prosthesis versus controls) and convergence analysis (Prosthetic Limb Users Survey of Mobility [PLUS-M] and Activities-Specific Balance Confidence [ABC] scale) were performed on 20 stability-related measures. Results The system was applied without complications; however, missing anticipatory postural adjustment data points for nine subjects affected the analysis. Of the 20 analyzed measures output by the sensors, only three significantly differed (P
