Objective: This study aimed to identify the clinical characteristics of patients achieving independent gait through Robot-Assisted Gait Training, based on their condition at the onset of the training.Methods: The subjects were patients after stroke who underwent 4 weeks of gait training using the Hybrid Assistive Limb® (HAL, Cyberdyne, Inc.). The assessment items were Functional Ambulation Categories (FAC), Stroke Impairment Assessment Set (SIAS), Fugl-Meyer Assessment (FMA) for lower extremity, Berg Balance Scale (BBS), Functional Independence Measure (FIM), and Hasegawa Dementia Scale-Revised (HDS-R). Patients with a FAC score of 3 or higher were classified as the independent group, while those with a FAC score of 2 or lower were classified as the assistance group. A univariate analysis was conducted with a significance level set at 5%.Results: Ten patients were in the independent group (mean age 73.2±13.8 years), while 7 patients were in the assistance group (mean age 83.6±6.1 years). The independent group demonstrated significantly higher scores in SIAS total score, BBS, FIM, and HDS-R (p<0.05). Additionally, the SIAS subscales assessing knee joint function, lower limb range of motion, abdominal muscle strength, verticality, and quadriceps muscle strength on the non-paralyzed side were all significantly higher in the independent group (p<0.05).Conclusion: Patients achieving independent gait through training with HAL were younger, exhibited lower levels of functional disability, demonstrated better balance, and showed a greater capacity to perform activities of daily living and cognitive function.
