Wearable Robotic Gait Training in Persons with Multiple Sclerosis: A Satisfaction Study

Wearable exoskeletons have showed improvements in levels of disability and quality of life in people with neurological disorders. However, it is important to understand users' perspectives. The aim of this study was to explore the patients' and physiotherapists' satisfaction from gait training with the EKSO GT(R) exoskeleton in people with multiple sclerosis (MS). A cross-sectional study with 54 participants was conducted. Clinical data and self-administered scales data were registered from all patients who performed sessions with EKSO GT(R). To evaluate patients' satisfaction the Quebec User Evaluation with Assistive Technology and Client Satisfaction Questionnaire were used. A high level of satisfaction was reported for patients and for physiotherapists. A moderate correlation was found between the number of sessions and the patients' satisfaction score (rho = 0.532; p < 0.001), and an excellent correlation between the physiotherapists' time of experience in neurology rehabilitation and the satisfaction with the possibility of combining the device with other gait trainings approaches (rho = 0.723; p = 0.003). This study demonstrates a good degree of satisfaction for people with MS (31.3 +/- 5.70 out of 40) and physiotherapists (38.50 +/- 3.67 out of 45 points) with the EKSO GT(R). Effectiveness, safety and impact on the patients' gait were the most highly rated characteristics of EKSO GT(R). Features such as comfort or weight of the device should be improved from the patients' perspectives.
