Clinical Trial Summary

Multiple sclerosis (MS) is a demyelinating neurodegenerative disease. Qualitative alterations in walking function in MS people involve 75% of subjects with MS and are determined by reduced coordination, mobility, balance, and increased risk of falling. Robot assisted gait training (RAGT) devices seem effective in MS patients with severe motor disabilities, failing to show significant superiority when compared to intensive overground gait rehabilitation (OGT). This study aims to evaluate the effects of a low-intensity RAGT at progressively increasing intensity compared to conventional RAGT and OGT.


Clinical Trial Description

Gait disorders are the most frequent symptoms associated to multiple sclerosis (MS).Robot-assisted gait training (RAGT) in people with MS (PwMS) has been proposed as a possible effective treatment option for severe motor disability. Although RAGT continues to prove effective in increasing patient mobility, no significant superiority was found when compared to intensive overground gait rehabilitation (OGT). In PwMS, RAGT at high-intensity may enhance fatigue and spasticity, compromising the effectiveness and applicability of the intervention. This study aims to evaluate the effects of a low-intensity RAGT at progressively increasing intensity compared to conventional RAGT and OGT in PwMS and moderate to severe walking impairment. We will recruit 24 PwMS from the patients afferent to Outpatient Rehabilitation Clinic at University Hospital of Ferrara and we will assign them to one of the three treatment groups: low-intensity RAGT at progressively increasing intensity, conventional RAGT and OGT. All participants will receive 3 weekly treatment sessions of 3 hours each for 4 weeks. In the first 2 hours of treatment, an experienced physiotherapist will propose a programme based on stretching exercises, muscle strengthening and educational interventions. During the last hour, subjects will undergo specific gait training according to the assignment group. Subjects allocated to low-intensity RAGT at progressively increasing intensity group will receive gait rehabilitation on the Lokomat device and a speed initially set at 1.0 km/h, with progressive increments of 0.1 km/h at each training session. The working time consists of bouts of 3 minutes of work alternated by 1 minute of recovery, to be repeated 8 times. Subjects allocated to conventional RAGT will receive gait rehabilitation on the Lokomat device and the machine parameters will be determined based on the patient's characteristics. Subjects allocated to OGT will perform a 40-minute walk on a flat surface supervised by a physiotherapist. Outcomes will be assessed before and after treatment and at 3-month follow-up. The primary outcome is walking speed. Secondary outcomes include mobility and balance, psychological measures, muscle oxygen consumption, electrical and hemodynamic brain activity, urinary biomarkers, usability, and acceptability of robotic devices for motor rehabilitation. ;
