To demonstrate the clinical efficacy and safety of its medical devices, Gogoa proactively conducts clinical trials and studies. Below are examples of pre- and post-marketing studies performed with Gogoa medical devices at leading centers and hospitals.
Note: H2 is the initial exoskeleton that lays the foundation for Hank's development.
Exoskeleton-based training improves
walking independence in incomplete spinal
cord injury patients: results from a randomized
controlled trial
A clinical trial published in the Journal of NeuroEngineering and Rehabilitation details the results of a rehabilitation trial using HANK, an ambulatory robotic exoskeleton for lower limbs. The trial was conducted on paraplegic patients with spinal cord injuries (SCIs) less than one year post-injury at the National Paraplegic Hospital in Toledo.
Robot therapy with the H2 exoskeleton for gait rehabilitation in patients with incomplete spinal cord injry. A clinical experience
A clinical trial was conducted using the HANK precursor exoskeleton (H2). The Exo H2 exoskeleton performed consistently throughout a gait rehabilitation clinical protocol. It proved to be a safe therapy, with no adverse effects and good patient tolerance. These results justify conducting clinical trials with an adequate sample size.
Joint stiffness tuning of exoskeleton robot H2 by tacit learning
This reference details the progress achieved in the design of an exoskeleton stiffness controller, based on the concept of tacit learning. This approach enables tactical management of the exoskeleton, eliminating the need for continuous human supervision.
Physiological evaluation of different control modes of lower limb robotic exoskeleton H2 in patients with incomplete spinal cord injury
This article has a strong physiotherapy focus, as its main author is a specialized physiotherapist. It addresses the effects of physical exercise on individuals with spinal cord injuries, using the H2 element as its central approach.
Integration of brain-computer interface and lower limb exoskeleton oriented to rehabilitation
This article could be considered slightly more general, as it describes a brain-computer interface (BCI) designed to control an exoskeleton. Through focused attention on the task, this system enables relatively free movement. However, the more one is distracted from the walking task, the less freedom the controller grants, encouraging a return to the task.
The H2 robotic exoskeleton for gait rehabilitation after stroke: early findings from a clinical study
A clinical trial was conducted with the HANK precursor exoskeleton (H2) at TIRR Memorial (Houston, Texas) with stroke patients. The objective was to evaluate the safety and usability of the medical device.
A flexible architecture to enhance wearable robots: Integration of EMG-informed models
The integration of the H2 exoskeleton with a neuromuscular model is detailed, with the aim of enabling them to operate together. A meticulous estimation of the generated torque is performed using a complex array of EMG electrodes applied to the exoskeleton.
Gait stability monitoring with exoskeletons based on proprioceptive information
This reference is fascinating, since by using the exoskeleton a simulation of a fall is carried out, allowing the algorithm to predict this event and thus take preventive measures regarding the use of the exoskeleton in case of a fall.
