Walking With Overground Robotic Exoskeleton Device to Increase Behavioral Responsiveness in Patients With Disorders of Consciousness (WALK DOC) (WALK DOC)
The goal of this observational study is to learn whether walking with an overground robotic exoskeleton (ORE) can improve responsiveness and brain activity in adults with disorders of consciousness (DoC) during inpatient rehabilitation after a severe brain injury. Participants include adults ages 18-70 who are in a coma, unresponsive wakefulness syndrome, or minimally conscious state and are receiving rehabilitation care at Spaulding Rehabilitation Hospital.
The main questions it aims to answer are:
- Does using an ORE improve behavioral responsiveness compared with lying down, sitting, or standing?
- Does using an ORE increase brain activity, and are changes in brain activity related to changes in responsiveness?
- Is ORE therapy safe, tolerable, and feasible for people with DoC during inpatient rehabilitation?
Researchers will compare participants' responses during sessions involving lying down, sitting, standing, and walking with the robotic exoskeleton to see if the exoskeleton leads to greater improvements in responsiveness and brain activity.
Participants will:
- Complete an initial screening session to determine whether they can safely use the robotic exoskeleton.
- Participate in six study sessions over about two weeks during their rehabilitation stay. During these sessions, participants will complete activities that may include lying down, sitting, standing, and walking with a robotic exoskeleton. The order of activities will be assigned at random.
- Have their level of responsiveness measured before and after each session using a standardized assessment called the Coma Recovery Scale-Revised (CRS-R).
- Wear a wireless EEG cap before, during, and after sessions so researchers can measure brain activity.
- Have their heart rate and safety monitored throughout the study sessions.

Patients with Disorders of Consciousness
Adults with a disorder of consciousness, such as coma, unresponsive wakefulness syndrome, or a minimally conscious state, who are receiving inpatient rehabilitation after a severe brain injury.
|
Participants will receive overground robotic exoskeleton-assisted standing and walking as part of inpatient rehabilitation.
Following a screening session to assess device fit and tolerance, participants complete supervised ORE sessions.
The intervention is distinguished by the use of assisted overground walking and upright mobility in individuals with disorders of consciousness and is evaluated in relation to behavioral responsiveness, brain activity, safety, tolerability, and feasibility.

|
Coma Recovery Scale-Revised (CRS-R)
Časové okno: From enrollment to end of study at 2 weeks
|
The Coma Recovery Scale-Revised (CRS-R) is a 23-item behavioral assessment used to evaluate consciousness in patients with brain injuries.
It measures auditory, visual, motor, oromotor, and communication functions.
The total score ranges from a minimum of 0 to a maximum of 23, with higher scores indicating a higher level of neurobehavioral function and conscious awareness.
CRS-R scores help characterize a patient's level of consciousness, including coma, vegetative state/unresponsive wakefulness syndrome, or minimally conscious state.

Disability Rating Scale (DRS)
Časové okno: Discharge from inpatient rehabilitation, an average of 8 weeks
|
The Disability Rating Scale (DRS) is an 8-item clinical tool used to track a patient's recovery from a moderate-to-severe traumatic brain injury (TBI) from the coma stage through to community living.
Scores range from 0 (no disability) to 29 (extreme vegetative state)
|
Discharge from inpatient rehabilitation, an average of 8 weeks

|
CARE (Continuity Assessment Record and Evaluation)
Časové okno: From inpatient admission through discharge from inpatient stay, assessed at routine intervals.
|
The CARE (Continuity Assessment Record and Evaluation) tool is a standardized CMS assessment used to measure the medical, functional, cognitive, and social needs of Medicare post-acute care patients The assessment evaluates four major domains:
|
From inpatient admission through discharge from inpatient stay, assessed at routine intervals.
|
|
Electroencephalogram (EEG)
Časové okno: Measured throughout 6 study assessment sessions conducted over 2 weeks during inpatient rehabilitation.
|
Cortical activity will be recorded continuously during the study sessions using a 24-channel mobile electroencephalography (EEG) system.
Key positional changes will be marked in the EEG recording.
EEG spectral power, including power within predefined brain wave frequency bands, will be evaluated before, during, and after positional changes.
Changes in these measures will be used to evaluate cortical activity across study conditions.
EEG frequency measures will be reported in hertz (Hz).
|
Measured throughout 6 study assessment sessions conducted over 2 weeks during inpatient rehabilitation.
|
|

N100 ERP responses will be assessed, reflecting auditory sensory processing.
For each response, the timing of the brain response (peak latency) will be measured.
ERP latency measures will be reported in milliseconds (ms).
|
Measured throughout 6 study assessment sessions conducted over 2 weeks during inpatient rehabilitation.
|
|
Event-Related Potential (ERP) - P300

ERP latency measures will be reported in milliseconds (ms).
|
Measured throughout 6 study assessment sessions conducted over 2 weeks during inpatient rehabilitation.
|
|
Event-Related Potential (ERP) - N400
Časové okno: Measured throughout 6 study assessment sessions conducted over 2 weeks during inpatient rehabilitation.
|
Event-related potentials (ERP) will be recorded before and immediately after each study session.
N400 ERP responses will be assessed, reflecting cognitive processing.
For each response, the timing of the brain response (peak latency) will be measured.
ERP latency measures will be reported in milliseconds (ms).
|
Measured throughout 6 study assessment sessions conducted over 2 weeks during inpatient rehabilitation.
|
|
Rate of Adverse Events (AE)
Časové okno: Measured throughout study participation, including during 6 study assessment sessions conducted over 2 weeks and at routine intervals as part of standard clinical care during inpatient rehabilitation.
|
Safety of the study will be measure via Rate of Adverse Events (AE).
Reported exoskeleton-emergent AE will include: increase in pain behavior or agitation, disconcerting changes in cardiovascular function (e.g., sudden drop in blood pressure), skin irritation or orthopedic injuries caused by the robotic exoskeleton device, sudden changes in alertness (e.g., somnolence), autonomic storming, and seizure activity.
|
Measured throughout study participation, including during 6 study assessment sessions conducted over 2 weeks and at routine intervals as part of standard clinical care during inpatient rehabilitation.
|
|
Heart Rate Reserve (HRR)
Časové okno: Measured throughout study participation, including during 6 study assessment sessions conducted over 2 weeks and at routine intervals as part of standard clinical care during inpatient rehabilitation.
|
Heart Rate Reserve (HRR) will be recorded as a measure of cardiovascular tolerability during the intervention.
A heart rate monitor will be used to record the amount of time spent in each heart rate zone during ORE sessions: very light (<30% HRR), light (30-39%), moderate (40-59%), vigorous (60-89%), and near maximal (>90%).
|
Measured throughout study participation, including during 6 study assessment sessions conducted over 2 weeks and at routine intervals as part of standard clinical care during inpatient rehabilitation.
|
|
Session completion rate (SCR)
Časové okno: Measured throughout study participation, including during 6 study assessment sessions conducted over 2 weeks and at routine intervals as part of standard clinical care during inpatient rehabilitation.
|
Session completion rate (SCR) will be used to assess the feasibility of completing the scheduled overground robotic exoskeleton sessions.
Feasibility will be measured by the percentage of scheduled sessions that each participant completes.
Based on prior clinical experience delivering exoskeleton sessions to patients with disorders of consciousness, successful session completion will be defined as completing at least 75% of the scheduled overground robotic exoskeleton sessions.
For any missed session, the reason for the missed session and whether the session was rescheduled or made up will be documented.
The time needed to complete any make-up sessions will also be recorded.
These data will help determine whether the intervention schedule is practical and manageable for participants.
