[Purpose] Cerebral palsy is one of the most common causes of childhood physical
disability affecting motor development. Gait training with a wearable-robot, such as the
Hybrid Assistive Limb, has been reported to improve gait ability in patients with chronic
motor disabilities; however, there are no reports concerning the sustained improvement of
walking ability with its use in patients with cerebral palsy. We present our observations
for the use of Hybrid Assistive Limb gait training in a postpubescent cerebral palsy
patient. [Participant and Methods] A 17-year-old male with spastic cerebral palsy could
only ambulate slightly using a crouch gait posture and with the aid of a walker. Hybrid
Assistive Limb training was performed thrice weekly for 4 weeks (total of 12 sessions)
along with concurrent daily physical therapy. The follow-up period was 7 months after the
intervention. [Results] The intervention resulted in improvements in the patient’s gait
speed, proportion of the stance phase in a gait cycle, step length, and the flexion angle
of the knees at initial contact and during late stance phase, which was sustained for 7
months following the intervention. [Conclusion] Our observations suggest that Hybrid
Assistive Limb training may effectively improve and sustain walking ability even among
postpubescent cerebral palsy patients who have a decreased walking ability.
