RESUMO
Welwalk WW-1000® (WW-1000®) is a gait exercise-assisted robot. Suitable assistance was provided to the patients with hemiplegic legs in both stance and swing phases. In addition，this robot offers various forms of feedback to patients during exercise. We present the case of a patient with multiple sclerosis and left hemiplegia who underwent WW-1000® gait exercise.The 73-year-old patient required maximum assistance with metal ankle foot orthotics (AFO) and a quadruped cane prior to robot-based rehabilitation. The aims of gait exercise with the WW-1000® were as follows；① maintain the verticality of the trunk during the entire gait cycle；②shifting the center of gravity during stance phase on the nonparalytic limb；③stabilizing the swing phase on the paralytic limb, and enhancing support during the stance phase on the paralytic limb. Each aim was modified depending on level of achievement. Assistance with the WW-1000® activated the trunk and Nonparalytic limb (visual feedback was utilized in exercises). On day 9, the patient could walk using a plastic AFO and T-cane supervised by a therapist.The multifunctional WW-1000® is useful for subdividing gait goals, exercise and set stepwise aims consistent with the patient's abilities. Gait exercises using the WW-1000® may efficiently improve gait and helps adapt to changes in conditions in the subacute phase.
