Study summary

The purpose of this study is to evaluate the feasibility of using a lower-limb exoskeleton in the intensive care unit for early mobilization of participants with intensive care neuromyopathy.

Read the detailed description

The participants' initial intensive care management will not be altered by the study. The study will begin at the end of their treatment, once organ failure has resolved and organ support has been discontinued. Participants with muscle weakness following intensive care will be eligible for exoskeleton-assisted rehabilitation sessions. In addition to their usual rehabilitation, participants will undergo a rehabilitation session lasting up to one hour, supervised by a physical therapist trained in the use of the exoskeleton.

The primary objective of the study is to assess feasibility based on the number of participants enrolled, the number of complete sessions completed, and the number of sessions per week. It also aims to assess technical feasibility by measuring the time required for setup and the number of staff needed to position the patient.

The secondary objectives focus on participant acceptability, safety, and efficacy by measuring the exoskeleton's impact on the incidence of PICS.

Study arms

  • Experimental
    Exoskeleton-Assisted Rehabilitation

    Daily exoskeleton-assisted rehabilitation for participants with resuscitation-associated neuromyopathy

    Device: rehabilitation session assisted by an exoskeleton

Interventions

  • Devicerehabilitation session assisted by an exoskeleton

    In this single arm, participants will be offered a rehabilitation session assisted by an exoskeleton. The session will consist of resuming walking under the supervision of a physical therapist. The duration of the session will be determined by the participant's perceived fatigue and will last a maximum of one hour if not limited by fatigue.
