Merging neural stimulation and exoskeletons to enhance sensorimotor hand functions after brain or spinal cord injury - Dataset

This repository contains all datasets and scripts necessary to reproduce the scientific results presented in: Cimolato et al. "Merging neural stimulation and exoskeletons to enhance sensorimotor hand functions after brain or spinal cord injury", published in Science Advances (2026). The repository is organized according to the figures presented in the manuscript to facilitate direct reproducibility of each published result. Figure 2 – NeuroSleeve Data-Informed Design electrode_placement_distributions.mDataset containing: i. the optimal locations of anode and cathode for FES of the flexor and extensor finger muscles; ii. the optimal locations of anode and cathode for TENS of the median and ulnar nerves. electrodes_diameter.matDataset containing electrode sizes that achieved optimal TENS-induced somatotopic feedback in healthy participants. improvement_thin_plate.matDataset containing force sensor recordings under no-load conditions, with and without the thin support plate. improvement_load_concentrator.matDataset containing grasp detection accuracy from force sensors across three grasp types (palmar pinch, spherical, cylindrical) Figure 3 – Range of Motion (RoM) Restoration rom_data.matDataset containing MCP joint Range of Motion values for participants under three conditions (no support, only exoskeleton support, SensibleExo support). Figure 4 – Sensory Restoration Mapping sensory_map_data.matDataset containg the percentage of sensitive area in the participants palm under three conditions (no support, with ulnar TENS, median TENS) Figure 5 – Functional Task Performance data_functional_task.matDataset containing task accuracy results for grasp and release tasks under three conditions (no support, with ulnar TENS, median TENS) with fragile and bulky objects. The dataset also includes participants’ quantified motor and sensory impairment percentages.
