Laboratory- and community-based health outcomes in people with transtibial amputation using crossover and energy-storing prosthetic feet: A randomized crossover trial
Fig 2
Activities along the mobility spectrum that ESF, RSF, and XF are estimated to span for most prosthetic limb users.
The black sections of the arrows indicate that the foot is well-designed for these activites, the faded sections indicate that the foot design can be used for these activities, however, performance may be suboptimal.
