Heatmaps showing changes (Δ) in lower extremity muscle activation data obtained from stroke-specific OpenSim biomechanical simulation using various configurations of the NewGait stroke-specific device. Bands placed overlaying (A) hip flexors and ankle dorsiflexors, (B) hip extensors and ankle dorsiflexors, (C) hip extensors and ankle plantarflexors, (D) hip flexors, hip abductors, and ankle dorsiflexors, and (E) hip extensors, hip abductors, and ankle dorsiflexors. Changes in muscle activation were computed by subtracting activation data during normal overground walking without the NewGait device from activation data during overground walking with the simulated NewGait device. Green on the heatmaps indicate a reduction in muscle activation (assistance) whereas red on the heatmaps indicate an increase in muscle activation (resistance).
