NCT02639481

Brief Summary

Patients with acquired brain injury (ABI) often suffer from severe disorders of consciousness (DOC), such as coma, unresponsive wakefulness syndrome (UWS), or minimally conscious state (MCS). This study examines the effect, a novel robotic rehabilitation device (the Erigo®Pro system) has on the recovery of consciousness of DOC patients. The device enables patients to be verticalized very early during acute neurorehabilitation and includes robotic leg movement training as well as functional electrical stimulation (FES) of leg nerves. Patients will be randomly allocated to one of three treatment groups: (i) control group with standard physiotherapy without the device, (ii) device treatment without FES, and (iii) device treatment with FES. Time until recovery of consciousness, rehabilitation outcome, and amount of complications will be the outcome variables.

Study Arms (3)

Control group standard physiotherapy

ACTIVE COMPARATOR

Patients will receive standard physiotherapy for 60 minutes, including the goal of verticalization and stimulation of the patient but without the use of the robotic Erigo®Pro device.

Behavioral: Standard physiotherapy

Erigo®Pro group without FES

ACTIVE COMPARATOR

Patients will receive 60 minutes of therapy with the robotic Erigo®Pro verticalization device but without functional electrical stimulation (FES) of the leg muscles.

Device: Erigo®Pro group without FES

Erigo®Pro group with FES

ACTIVE COMPARATOR

Patients will receive 60 minutes of therapy with the robotic Erigo®Pro verticalization device including functional electrical stimulation (FES) of the leg muscles.

Device: Erigo®Pro group with FES

Interventions

Classical standard physiotherapy, including measures to verticalize patients by means of orthesis, classical tilt tables, or castings

Control group standard physiotherapy

Use of the Erigo®Pro device to verticalize patients to above 60° while performing robotic stepping leg movements. FES ist not used.

Erigo®Pro group without FES

Use of the Erigo®Pro device to verticalize patients to above 60° while performing robotic stepping leg movements. FES is applied during then whole treatment session, providing electrical stimulation to the muscles of the upper and lower leg, synchronous to the robotic stepping movements

Erigo®Pro group with FES
