RESUMEN
OBJECTIVE: To investigate the feasibility and safety of robotic-assisted gait training (RAGT) in adults with disorders of consciousness (DoC). SETTING: Inpatient rehabilitation hospital. PARTICIPANTS: Four adult male patients with traumatic brain injury and DoC. DESIGN: Subjects participated in RAGT with body weight support for 5 to 20 minutes, over 1- to 2-week periods. MAIN MEASURES: Primary measures included vital signs, walking parameters, pain, arousal, and Agitation Behavior Scale scores. Additional data included Modified Ashworth Scale, Coma Recovery Scale-Revised, and Rancho Los Amigos Scale scores. RESULTS: All participants safely completed at least one session of RAGT with body weight support with safe vital signs and low agitation levels. Two adverse events occurred (increased somnolence and pain due to harness placement), which were not considered severe. All subjects emerged out of DoC at which point research protocol was stopped. CONCLUSIONS: Findings suggest inpatient-based RAGT may be safe and feasible to consider when developing a therapy plan of care in adults with DoC.
