| Summary: | Robotic-assisted therapy (RAT) is a task-specific approach for treating gait disorders in individuals with neurological impairments. However, the effectiveness of RAT is not clear for different severities of involvement, pathologies, and ages. This study aimed to assess the functional and clinical status outcomes after RAT in individuals with cerebral palsy (CP). Twenty-eight individuals with bilateral spastic CP were enrolled (female = 10; male = 18; age = 15.2 ± 2.0 years). The RAT program consisted of 30 sessions: five sessions weekly for six weeks. Gross Motor Function Measure (GMFM) and clinical physical examinations were evaluated before and after RAT. Our results suggested that the RAT program with the described protocol can improve the general gross motor functions of individuals with CP in Gross Motor Function Classification System (GMFCS) levels I and II, and primarily improves performance on less complex GMFM items for those in GMFCS levels III and IV. The lower baseline functional level was related to a greater functional improvement. Older individuals were noticed to improve more in GMFM dimension D. Regarding impairments evaluated by clinical examinations, no change was found after RAT intervention. It is worth mentioning that the strength of knee muscles was not affected either.
