Acquired brain injury often results in hemiparesis, causing significant deficits in balance and gait that adversely affect functional ambulation and participation in activities of daily living. Gait training using robotic exoskeletons offers an option for motor rehabilitation in individuals with hemiparesis, but few studies have been conducted in adolescents and young adults. Findings from a preliminary study in this age group show promise for this intervention, according to Drs. Karunakaran and Nolan, in a media release from Kessler Foundation.
Participants included seven individuals (aged 13 to 28 years) with acquired brain injury (ABI) and hemiparesis and one healthy control. The ABI group included individuals with brain injuries due to anoxia, trauma, and stroke. All participants received 12 45-minute sessions of high-dose, repetitive gait training in a robotic exoskeleton (EksoGT, Ekso Bionics Inc) over a 4-week period.
The gait training was administered by a licensed physical therapist supervised by a member of the research team.
“At the end of the 4-week training, participants had progressed to a more normal gait pattern, including improved loading, a longer step length and faster walking speed.”

Although results are promising, the study has limitations, including small sample size and lack of a control group.
“Further study is needed to confirm the training effect in this age group with ABI, optimal dosing for the training protocol, and the durability of functional improvements.”
