Individualized tuning of exosuit force settings
The soft robotic exosuit’s plantarflexor force settings were tuned for each user prior to REAL gait training. The effects of four different plantarflexor force profiles were examined prior to the start of training (Fig. During the tuning procedure, study participants completed 2-minute trials on an instrumented treadmill (Bertec, Columbus, Ohio, USA) for each tested condition. The last 30 s of walking was used for data analysis. Testing was conducted at each study participant’s fast walking speed; walking speed was matched across all conditions. The user-individualized plantarflexor force profile selected for use during REAL training (see Fig.
