use (mPEQ), self-developed questionnaire on perceived difficulty to perform 45 activities of daily living (ADL) with a rating scale from 1 for "very difficult" to 6 for "very easy". Results or Clinical Course: The total mPEQ score was significantly improved (p¼.02) when using the OBS as were the subdomains of ambulation (p¼.003), paretic limb health (p¼.02), well-being (p¼.02), and sounds (p¼.008). In the total group, 22 of the 45 ADLs surveyed were perceived significantly easier to perform with the OBS than with the previous orthotic devices. As compared to locked KAFO and SCO use, 12 ADLs and 5 ADLs, respectively, were perceived significantly easier to perform when using the OBS, all related to controlled knee flexion during weight bearing that is not allowed for by the traditional leg orthoses. Conclusions: The orthotronic mobility system improves the perceived walking capabilities of traditional leg orthosis users. Further research using performance-based outcome measures has been initiated and is ongoing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
