<p>The effectiveness of robotic exoskeletons for post-stroke gait rehabilitation might be limited as the control parameters these devices do not adapt to key biomechanical descriptors. The main contribution this study is examine with aim finding relationships between exoskeleton and a comprehensive set metrics. Five stroke survivors walked assistance wearable ankle (ABLE-S) using different levels plantarflexion (PF) dorsiflexion (DF) peak torque, well timings PF torque. We found that DF magnitude had significant negative relations temporal symmetry index (p = 0.033) paretic foot absolute angle at heel strike 0.019). Changes in applied were significantly correlated high variety spatial parameters, e.g., walking speed 0.009), stride length 0.011), non-paretic step 0.024), clearance 0.003) hip hiking 0.038), muscle activation side, Tibialis Anterior 0.049) Gastrocnemius Medialis 0.049). Based on our results, we propose laws adapting will evaluated future work.</p>
