Exploring mechanical work changes in controlled ankle motion (CAM) boot walking: The effects of gait speed and shoe levelling
Fig 4
Hip joint mechanical work (Whip) 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.
Whip (relative to body mass) was similar between conditions but increased with speed. Whip (relative contribution to total mechanical work) was mostly lower in NORM at PWS and in the standardised speeds, although this was not the case for the contralateral limb at standardised speeds. Ipsilateral Whip (relative contribution to total mechanical work) was lower at higher speeds, but the contralateral limb did not change. PWS = preferred walking speed. Data pertaining to this figure, along with a summary of statistical results, can be found in S1 Table.
