Trial summary

75% patients in the chronic phase of a stroke keep walking disabilities. Focal spasticity in the paretic lower limb frequently causes these walking disabilities, and the gold standard treatment is intramuscular injection of Botulinum toxin A in the spastic muscles. Read more about this study

About this study

Official title: Effects of Combined Treatment by Botulinum Toxin A and Robot-Assisted Gait Training (Lokomat®) on Walking Ability in Patients With Chronic Stroke: a Prospective, Controlled, Randomized Study

75% patients in the chronic phase of a stroke keep walking disabilities. Focal spasticity in the paretic lower limb frequently causes these walking disabilities, and the gold standard treatment is intramuscular injection of Botulinum toxin A in the spastic muscles.

To potentiate the effects of toxin, walking rehabilitation is usually prescribed in the weeks following injection, but the protocols vary and few have been evaluated in the medical literature.

Read more

In particular, the effect on walking ability of combined treatment by botulinum toxin A and robot-assisted gait training has never been evaluated.

Tested hypothesis: Robot-assisted gait training by Lokomat® motorized exoskeleton potentiates botulinum toxin's effects better than conventional walking therapy.

The aim of this study was to evaluate the effects on walking ability of the association of focal spasticity treatment by Botulinum toxin and Lokomat-assisted walking rehabilitation in patients suffering from spastic hemiparesia after stroke in the chronic phase.

Outcome:

-Primary: distance walked (meters) in the six-minute walk test (SMWT)

Prospective, randomized, controlled, opened, monocentric study with a crossover design.

Recruitment of patients over 18 years of age, in the chronic phase of stroke, who have already been treated by Botulinum toxin injection for focal spasticity in our PMR ward.

Assessment at Day one (D0), Week four (W4) and Week eight (W8).

Following a preliminary study which had the six-minute walk test as a secondary outcome, the expected results are a significant improvement of the distance walked in the SMWT after robotic rehabilitation, and a lack of significant improvement following conventional therapy.

The study should serve to further harmonize and optimize rehabilitation protocols after toxin injections, and to justify the use of robotic rehabilitation for patients in the chronic phase of stroke.

Read the detailed description

Introduction :

75% patients in the chronic phase of a stroke (>6 months) keep walking disabilities. Focal spasticity in the paretic lower limb frequently causes these walking disabilities, and the gold standard treatment is intramuscular injection of Botulinum toxin A in the spastic muscles.

To potentiate the effects of toxin, walking rehabilitation is usually prescribed in the weeks following injection, but the protocols vary and few have been evaluated in the medical literature.

In particular, the effect on walking ability of combined treatment by botulinum toxin A and robot-assisted gait training has never been evaluated.

Materials and Methods:

Tested hypothesis:

Robot-assisted gait training by Lokomat® motorized exoskeleton potentiates botulinum toxin's effects better than conventional walking therapy.

Aims:

  • Primary: to evaluate the effects on walking ability of the association of focal spasticity treatment by Botulinum toxin and Lokomat-assisted walking rehabilitation in patients suffering from spastic hemiparesia after stroke in the chronic phase.
  • Secondary: to determine the optimal time between the toxin injection and the start of robotic rehabilitation; to evaluate the effects of the combined treatment on the balance and spasticity.

Outcome:

  • Primary: distance walked (meters) in the six-minute walk test (SMWT)
  • Secondary: walking speed (meters/seconds), balance (Timed Up and Go Test, Berg Balance Scale), spasticity (score on the Modified Ashworth Scale and joint range of motion)

Study Design:

Prospective, randomized, controlled, opened, monocentric study with a crossover design.

Recruitment of patients over 18 years of age, in the chronic phase of stroke, who have already been treated by Botulinum toxin injection for focal spasticity in our PMR ward.

Assessment at Day one (D0), Week four (W4) and Week eight (W8).

  1. st Group D0: Injection of Botulinum toxin A in triceps surae, according to pre-established modalities (no influence of the experimental protocol on this stage) W2-W4: Robotic walking rehabilitation by Lokomat® in the functional rehabilitation department (conventional hospitalization) W4-W6: Return to home, "wash-out"period W6-W8: Conventional walking rehabilitation in the functional rehabilitation department (conventional hospitalization)
  2. nd Group: D0: Injection of Botulinum toxin A in triceps surae W2-W4: Conventional walking rehabilitation in the functional rehabilitation department (conventional hospitalization) W4-W6: Return to home, "wash-out"period W6-W8: Robotic walking rehabilitation by Lokomat® in the functional rehabilitation department (conventional hospitalization)

Expected results:

Following a preliminary study which had the six-minute walk test as a secondary outcome, the expected results are a significant improvement of the distance walked in the SMWT after robotic rehabilitation, and a lack of significant improvement following conventional therapy.

The study should serve to further harmonize and optimize rehabilitation protocols after toxin injections, and to justify the use of robotic rehabilitation for patients in the chronic phase of stroke.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time of Ten-meter walk test

    Time is measure while the individual walks the set distance (10 meters). the distance covered is divided by the time it took the individual to walk that distance

    Measured: 20 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Robotic walking rehabilitation by Lokomat® and Conventional walking rehabilitation in people with Stroke, run by Assistance Publique Hopitaux De Marseille at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 14 Jun 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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?

Time of Ten-meter walk test (time frame: 20 minutes). 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 14 Jun 2024.
