Effectiveness of robot-assisted gait training on freezing of gait in people with Parkinson disease: evidence from a literature review

The aim of this review was to evaluate, summarize and discuss the available literature concerning the effect of robot-assisted gait training (RAGT) on patient with Parkinson disease (PD) and freezing of gait (FOG). A comprehensive literature search was conducted utilizing of MEDLINE, Embase, Scopus, Web of Science, PEDro (Physiotherapy Evidence Database), and the Cochrane Review. Search terms used in-cluded ‘Parkinson disease,’ ‘Freezing of gait,’ ‘RAGT,’ ‘robot-assisted gait training,’ ‘Locomotor rehabilitation,’ ‘gait trainer,’ and ‘robotics assisted gait training.’ A total of 4 studies were evaluated, but these studies were primarily of low-level evidence. All the 4 studies noted positive outcomes with using RAGT on FOG. No adverse events or side effects that occurred during and/or after the interventions. While the current literature generally offers support for the use of RAGT for FOG treatment, there is a paucity of strong evidence to support its widespread use. The increasing availability of RAGT technology offers the potential for engaging therapy in FOG rehabilitation, but its utility remains uncertain given the limited studies available at this time.
