High-dose therapy gait training using robotic exoskeletons may aid early rehabilitation for acute stroke, a study published in Frontiers in Neurorobotics suggests.
In the study, researchers from Kessler Foundation used an Ekso GT robotic exoskeleton from Ekso Bionics Inc to demonstrate the potential to improve gait training after acute stroke toward the goal of earlier recovery of motor function.
Gait Training vs Standard of Care
Participants included 44 individuals (ages 18 to 82 years) admitted to Kessler Institute for Rehabilitation for acute stroke. Half received conventional standard of care (SOC), and half received SOC with an option for overground gait training in the Ekso GT (RE+SOC). Both groups received the same amount of overall therapy time.
Overground gait training in the exoskeleton was supervised by a licensed physical therapist who adjusted the variable bilateral assistance of the Ekso GT according to each individual’s progress. Outcome measures were total distance walked during inpatient rehabilitation and functional independence measure (FIM) score. The RE-SOC group trained in the Ekso GT at least three times during their stay.
“We found that gait training in the exoskeleton allowed us to increase the dose of gait training without increasing the duration of inpatient rehabilitation. Because overground walking in the exoskeleton requires active effort on the part of the participant, early intervention with this type of gait training promotes brain plasticity that may lead to greater functional improvements and more lasting effects when combined with conventional training.”
