Exploring mechanical work changes in controlled ankle motion (CAM) boot walking: The effects of gait speed and shoe levelling
Fig 2
Ankle joint mechanical work (Wankle) for each footwear condition at each speed, displayed relative to body mass in the contralateral (A) and ipsilateral (B) limb, and as a relative contribution to total mechanical work in the contralateral (C) and ipsilateral (D) limb.
Ipsilateral Wankle was lower in BOOT and EVEN, compared to NORM in all cases. Contralateral Wankle (relative to body mass) was lower in BOOT at PWS, but not in the standardised speeds, and increased with speed. Contralateral Wankle (relative contribution to total mechanical work) was lower in EVEN at PWS and at standardised speeds, as well as being lower at higher speeds. PWS = preferred walking speed. Data pertaining to this figure, along with a summary of statistical results, can be found in S1 Table.
