Gait impairment in neurological disorders: a new technological approach.

Gait recovery is considered one of the main objectives of rehabilitation interventions in neurological disabilities, as restricted movement can significantly reduce an individual's ability to take part in normal activities of daily living. Locomotor training has been shown to improve gait rehabilitation. Studies have recently been published on the use of robots and other devices in patients with gait disabilities, particularly in the rehabilitation of the lower limbs. However, analysis of the recent literature reveals a relative paucity of strong methodological studies. The evidence that is available, while strong, is not yet sufficient to allow definite conclusions to be drawn regarding the efficacy of these devices. From these considerations, it is clear that validated and standardized methods need to be adopted for each of the different systems available. This would help to clarify the indications for and correct use of robotic devices in the different neurological disorders.
