User Needs and Limitations of Existing Mobility Devices

Abstract

The use of gait assistive devices, although can provide precious help can also have limitations or adverse consequences. The performance of daily activities is partially restrained by a series of factors having to do with the assistive device limitations or the limitations emerged from environmental causes. Valid and reliable assessment tools to classify and clarify their limitations or users' satisfaction do not exist. An extended literature search was performed for some of the most commonly mentioned assistive device limitations or dissatisfaction reasons and identified the most appropriate tools to be able to study such limitations and conclude in valid outcomes. A study was conducted in a rehabilitation hospital using the IPA, EQ5D and SF-12 tools. The size of the sample combined with the uncertainty related to the satisfaction of normal distribution prerequisite, led to use several statistical analysis tools and methodologies. A summary of the results from both the literature review and the real case study on a mixed group of mobility aid users are presented in the paper.
