Subjects were assigned to 1 of 3 parallel arms for 12 weeks (6 weeks/device): arm 1 (WA-AFO), n = 38; arm 2 (AFO-WA), n = 31; arm 3 (AFO-AFO), n = 24. Primary outcomes were walking speed and Physiological Cost Index for the Figure-of-8 walking test. Secondary measures included 10-m walking speed and perceived safety during this test, general mobility, and device preference for arms 1 and 2 for continued use. Walking tests were performed with (On) and without a device (Off) at 0, 3, 6, 9, and 12 weeks.\nRESULTS: Both WA and AFO had significant orthotic (On-Off difference), therapeutic (change over time when Off), and combined (change over time On vs baseline Off) effects on walking speed. An AFO also had a significant orthotic effect on Physiological Cost Index. The WA had a higher, but not significantly different therapeutic effect on speed than an AFO, whereas an AFO had a greater orthotic effect than the WA (significant at 12 weeks). Combined effects on speed after 6 weeks did not differ between devices. Users felt as safe with the WA as with an AFO, but significantly more users preferred the WA.\nCONCLUSIONS: Both devices produce equivalent functional gains.","tracks":[{"project":"Allie","denotations":[{"id":"SS1_23558080_4_0","span":{"begin":332,"end":340},"obj":"expanded"},{"id":"SS2_23558080_4_0","span":{"begin":342,"end":344},"obj":"abbr"},{"id":"SS1_23558080_4_1","span":{"begin":386,"end":405},"obj":"expanded"},{"id":"SS2_23558080_4_1","span":{"begin":407,"end":410},"obj":"abbr"}],"relations":[{"id":"AE1_23558080_4_0","pred":"abbreviatedTo","subj":"SS1_23558080_4_0","obj":"SS2_23558080_4_0"},{"id":"AE1_23558080_4_1","pred":"abbreviatedTo","subj":"SS1_23558080_4_1","obj":"SS2_23558080_4_1"}],"attributes":[{"subj":"SS1_23558080_4_0","pred":"source","obj":"Allie"},{"subj":"SS2_23558080_4_0","pred":"source","obj":"Allie"},{"subj":"SS1_23558080_4_1","pred":"source","obj":"Allie"},{"subj":"SS2_23558080_4_1","pred":"source","obj":"Allie"}]},{"project":"PubmedHPO","denotations":[{"id":"T1","span":{"begin":246,"end":255},"obj":"HP_0009027"},{"id":"T2","span":{"begin":262,"end":268},"obj":"HP_0001297"}],"attributes":[{"subj":"T1","pred":"source","obj":"PubmedHPO"},{"subj":"T2","pred":"source","obj":"PubmedHPO"}]},{"project":"yangbin123xm_800_3","denotations":[{"id":"T1","span":{"begin":86,"end":92},"obj":"DP"},{"id":"T2","span":{"begin":262,"end":268},"obj":"DP"},{"id":"T3","span":{"begin":439,"end":445},"obj":"DP"}],"attributes":[{"subj":"T1","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T2","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T3","pred":"source","obj":"yangbin123xm_800_3"}]},{"project":"chenxin_473849_800_3","denotations":[{"id":"T1","span":{"begin":86,"end":92},"obj":"DP"},{"id":"T2","span":{"begin":262,"end":268},"obj":"DP"},{"id":"T3","span":{"begin":439,"end":445},"obj":"DP"}],"attributes":[{"subj":"T1","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T2","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T3","pred":"source","obj":"chenxin_473849_800_3"}]}],"config":{"attribute types":[{"pred":"source","value type":"selection","values":[{"id":"Allie","color":"#ecba93","default":true},{"id":"PubmedHPO","color":"#a093ec"},{"id":"yangbin123xm_800_3","color":"#9fec93"},{"id":"chenxin_473849_800_3","color":"#ec93b9"}]}]}}
