The objective of this study is to define clinically meaningful change in the walking function of lower limb prosthetic users in order to more easily assess whether a patient is improving or declining in function over time. However, little is known about the natural fluctuations in walking metrics from week to week when walking function is stable versus clinically relevant changes in walking function. Therefore, it will be important to define meaningful change in walking function when interpreting the impact of prosthetic components, rehabilitation, and other treatments on real world walking. Recruitment has been completed and data collection is completed. A total of 100 subjects have enrolled in the study with data collection on n89. Analysis indicated that patient perception was multifaceted and recall was problematic. Cut-points did not provided the clinical meaning expected. This study determined that walking change that exceeded the natural variation of each patient is clinically relevant rather than an average that can be applied to all.
