About this study

Official title: Usability of a New Overground Body Weight Support Rehabilitation Robot LEAP: A Monocentric Consideration-of-concept Trial

People with central nervous system disorders such as spinal cord injury, stroke, cerebral palsy, Parkinson's disease, multiple sclerosis, etc… often have impaired lower extremity function that limits activities of daily life and independence. Different body-weight support systems have been developed to facilitate the rehabilitation process by compensating for the user's residual abilities. However, studies on weight-supported gait training on a treadmill have failed to show superiority over conventional rehabilitation programs for spinal cord injury and stroke. A recent study by the group around Grégoire Courtine showed that body-weight support systems that provide assistance only in the vertical direction disrupt the production of gait and balance, suggesting that current practices may even be detrimental for relearning to walk. For the past year, the Clinique Romande de Réadaptation (CRR) worked together with the G-Lab at EPFL and G-Therapeutics on a new robot platform specifically developed to provide adjustable trunk support along four independent degrees of freedom (LEAP). The investigators were able to draw on their long-term experience, which consists of different body weight support training systems for stroke and spinal cord injury. This knowledge, combined with the input of our therapists and physicians and the specific requirements for people with neurological/musculoskeletal disorders, has resulted in a design that can provide adjustable bodyweight support during over-ground locomotion, treadmill, stairs training, standing up and sitting down and for support during the training of activities of daily living.

The scope of this study is to examine how well the robot can be used for rehabilitation therapy in everyday clinical practice. This includes, among other things, technical aspects such as the handling of the hardware, the adaptability of the robot to the patient, and the safety during operation (such as the fall prevention). Various patient-specific aspects will also be evaluated e.g. comfort, positioning, or motivation of the patient. This study also aims to evaluate the software with the various support modes, operating options, and the user interface of the LEAP.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Therapist LEAP session feedbackDevice

    A standard therapy session is being performed with a participant with the LEAP body-weight support robot. Subsequently, the therapist is answering a questionnaire to assess the clinical applicability of the robot. An observer will assess with a questionnaire whether use errors occurred during the session.

  • Participant LEAP session feedbackDevice

    A standard therapy session is being performed with a participant inside the LEAP body-weight support robot. Subsequently, the participant is answering a questionnaire to assess the comfort of the robot.

  • LEAP risk control validationDevice

    The therapist rates the risk control measurements of the LEAP robot with a questionnaire, during a session with a member of the investigational team.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Usability of the robot - Fixation (time frame: 2 minutes). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03458169, which also lists 40 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 30 Jan 2019.
