About this study

Official title: Clinical Trial to Compare Conventional Multidisciplinary Gait Rehabilitation With the Atalante Self-balancing Walking System in Patients With Multiple Sclerosis

This trial is a prospective, randomized, rater-blinded study (cRHB (N=30) vs RAGT (N=30)). For the control group, this protocol includes 24 one-hour sessions of cRHB training during 8 weeks three times per week, under the supervision of a qualified rehab team.

For the intervention group (RAGT) this protocol includes 24 one-hour sessions of RAGT during 8 weeks three times per week, under the supervision of a qualified rehab team.

Informed consent will be obtained from patients prior to inclusion in the study, which will be carried out in accordance with the Declaration of Helsinki.

Aims

Primary Aim:

To compare the effect of Robot-Assisted Gait Training (RAGT) using the Atalante self-balance exoskeleton with conventional rehabilitation training (cRHB) for improving Walking speed measured by the Timed 10-meters walk test (10-MWT), considering a clinically relevant change an improvement of 20% of the velocity (m/s) with respect to the baseline assessment.

Secondary Aims:

  • To compare the effect of RAGT using the Atalante self-balance exoskeleton with conventional Rehabilitation training (cRHB), for improving static balance, dynamic balance, mobility, and self-perception of gait impairment measured with:
  • Static Balance by the Berg Balance Scale (BBS), considering a clinically relevant change for improvement in balance as measured by BBS was +3 points, meaning that individuals are likely to perceive that as a reproducible and clinically important change in their balance performance.
  • Dynamic balance by the Timed Up and Go test (TUG)
  • Mobility measured by modified Rivermead Mobility Index (mRMI)
  • Self-perception of gait impairment by Multiple Sclerosis Walking Scale-12 (MSWS-12)
  • Instrumented gait analysis by the G-walk device (assessing gait cycle duration, step length, propulsion index, support phase percentage D/I, oscillation phase percentage D/I, double/unique support phase percentage).
  • To compare the effect of RAGT using the Atalante self-balance exoskeleton with conventional Rehabilitation training (cRHB) on quality of life, emotional status and fatigue measured at pre and post-intervention with:
  • Multiple Sclerosis Quality of Life-54 (MSQoL 54 Health Survey Spanish version)
  • Hospital Anxiety and Depression Scale (HADs) considering a clinically relevant change of 1.7 points at HADs
  • The Modified fatigue scale (MFIS)
  • The patient' physical effort of each session by means of the scale of perception of the effort R.P.E of Borg at the end of each training.
  • To evaluate the epigenetic blueprint of rehabilitation training by comparing the genome wide chromatin accessibility of peripheral blood mononuclear cells (PBMCs) before and after RAGT or cRHB, by Assay for Transposase-Accessible Chromatin sequencing (ATACseq).
  • To test the hypothesis that genome wide chromatin accessibility compared to clinical measures can be useful for identifying molecular mechanisms underlying rehabilitation therapies.
  • To compare the changes induced by RAGT versus cRHB on the overall chromatin accessibility, and specific genome regions and pathways.
  • Use the biological samples to provide additional functional and mechanistic information about the rehabilitation effects and subject health, disease or state.

Materials And methods

Design:

This trial is a prospective, randomized, rater-blinded study (cRHB (N=30) vs RAGT (N=30)).

For the control group, this protocol includes 24 one-hour sessions of cRHB training during 8 weeks three times per week, under the supervision of a qualified rehab team.

For the intervention group (RAGT) this protocol includes 24 one-hour sessions of RAGT during 8 weeks three times per week, under the supervision of a qualified rehab team.

Additionally, peripheral blood (6ml) will be taken from all subjects at three timepoints: at baseline (T1), after the 8 weeks of rehabilitation treatment (T2) and, if possible, one year after T4. Biological samples will then be given a unique identifier and transferred to researchers for analysis.

Informed consent will be obtained from patients prior to inclusion in the study, which will be carried out in accordance with the Declaration of Helsinki.

Enrollment and Screening Subjects will be evaluated for their eligibility from neurorehabilitation and neurology outpatient clinics at the Multiple Sclerosis Center of Catalonia (Cemcat).

Potential subjects will be referred to the study via Cemcat Physicians. A member of the research team will screen the referral and confirm they meet the necessary inclusion and exclusion criteria. Following confirmation of criteria, potential subjects will be contacted by phone to schedule an initial visit for consent and baseline assessment.

Additionally, peripheral blood (6ml) will also be taken from all subjects at baseline (T1).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Robotic gait trainingDevice

    Also called Robotic, Atalante Gait Training

    RAGT group, will be trained 3-times per week, with an intensity of 40 to 60 minutes, and duration over 8-weeks. Progression will occur by increasing the session intensity weekly. Training intensity will be monitored and standardized using the Borg Rating of Perceived Exertion scale, and will progress from 'fairly light' to 'somewhat hard'.

    Progression will occur by increasing the number of steps in each session and decrease the level of assistance.

    Participants will be secured with the appropriately sized harness and attached to an overhead body-weight support system. Each session will begin with a 3-5-minute warm-up in the continuous passive mode (cadence ~40-45 steps/minute). The participant will then be transitioned into the adaptive training phase for practicing repetitive floor walking for up to 30 minutes. During this phase, the force produced by the robot is modulated to support the effort of the patient in producing a typical walking pattern.

  • tRHBOther

    Also called Physical therapy, gait training

    Participants randomize to receive a tRHB, will be trained 3 times per week, with an intensity of 40 to 60 minutes, and duration over 8-weeks. Progression will occur by increasing the session intensity weekly.

    A standardized protocol based on the usual clinical practice of physiotherapy in people with multiple sclerosis will be follow, according to patient characteristics, to design the sessions based on the patient objectives to be achieved, choosing the type of specific exercises to be performed based on the patient's condition and with the possibility of adapting them to their evolution during the twenty-four sessions.

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Timed 10-meters walk test (10-MWT), (time frame: 2 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2026.
