Long-term sustained effect of gait training using a hybrid assistive limb on gait stability via prevention of knee collapse in a patient with cerebral palsy: a case report.

This is a single-patient case report, so it cannot show that hybrid assistive limb training works for people with cerebral palsy. The patient received conventional physical therapy during and after hybrid assistive limb training, so the contribution of any single component cannot be separated. The gross motor function classification level did not improve at 8-month follow-up. Changes were absent at 1-month follow-up but present at 4-month and 8-month follow-up, so the timing of reported improvements was inconsistent. The paper compares baseline with later measurements in one patient, not with another group, so it cannot tell whether the changes were caused by the intervention.

Do not conclude that hybrid assistive limb training prevents knee collapse or improves gait stability in cerebral palsy. This was one patient, he also received conventional physical therapy, and his gross motor function classification level did not improve.
