In order to demonstrate the clinical efficacy and safety of medical devices, Gogoa proactively conducts clinical trials and studies. Below you can see the pre-post-marketing studies conducted with Gogoa's medical devices in major centres and reference hospitals.

Exoskeleton‑based training improves
walking independence in incomplete spinal
cord injury patients: results from a randomized
controlled trial

Clinical trial published in the Journal of NeuroEngineering and Rehabilitation detailing the results of a rehabilitation trial with HANK, an ambulatory robotic exoskeleton for lower limbs. The trial was conducted in paraplegic patients with spinal cord injury (SCI) less than 1 year after injury at the Hospital Nacional de Parapléjicos de Toledo.

Robot therapy with the H2 exoskeleton for gait rehabilitation in patients with incomplete spinal cord injry. A clinical experience

Clinical trial conducted with the HANK precursor exoskeleton (H2). The performance of the Exo H2 exoskeleton was consistent during a clinical gait rehabilitation protocol. It was shown to be a safe therapy with no unwanted effects and good patient tolerance. These results justify clinical trials with an adequate sample size.

Joint stiffness tuning of exoskeleton robot H2 by tacit learning

This reference details the progress made in the design of an exoskeleton stiffness controller based on the concept of tacit learning. This approach enables tactical management of the exoskeleton without 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 physiotherapeutic slant, as the main author is a specialist physiotherapist. It deals with the effects of physical exercise on people with spinal cord injuries, using the H2 element as an approach.

Integration of brain-computer interface and rehabilitation-oriented lower limb exoskeleton

This article could be considered slightly more generic, as it presents a brain-computer interface (BCI) designed to control an exoskeleton. Through task-focused attention, this system enables relatively free movement. However, the more one is distracted from the walking task, the less freedom is granted by the controller, providing an incentive to refocus on the walking task.

Theoretical approach for designing the rehabilitation robot controller

This paper details the implementation of the tacit learning controller in the exoskeleton.

Hybrid: ambulatory robotic gait Trainer with movement induction and partial weight support

A study using partial weight-suspended exoskeleton technology has yielded revealing results about the capabilities of this tool.

Quantifying the Impact of a Lower Limb Exoskeleton on Whole-Body Manipulation Tasks. Methodological Approach and First Results

This allusion goes into the industrial field, focusing on the application of the exoskeleton for the execution of load handling tasks and its impact on movement.

The H2 robotic exoskeleton for gait rehabilitation after stroke: early findings from a clinical study

Clinical trial 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 purpose of operating in tandem. A thorough estimation of the torque generated using a complex arrangement of EMG electrodes is carried out and applied to the exoskeleton.

Testing the generation of speed-dependent gait trajectories to control a 6DoF overground exoskeleton

In this context, extensive testing of the trajectories being integrated into HANK's innovative adaptive mode is being carried out.

Muscle activity and coordination during robot-assisted walking with H2 exoskeleton

This article, although written by an engineer, focuses extensively on the study of muscle activity during H2 use.

An integrated lower limb exoskeleton and body weight support system: design and implementation

This text presents the meticulous description of the synergy between the H2 exoskeleton and a partial weight suspension crane.

Voluntary control of wearable robotic exoskeletons by patients with paresis via neuromechanical modeling

This is a remarkable reference involving the control of the exoskeleton in harmony with a sophisticated neuromusculoskeletal model.

Monitoring of gait stability with exoskeletons based on proprioceptive information

This is an intriguing reference, as by using the exoskeleton, a simulation of a fall is carried out, allowing the algorithm to predict such an event and thus take preventive measures regarding the use of the exoskeleton in case of a fall.
