Trial summary

Stiff knee gait is defined as the lack of knee flexion in the swing phase of gait. Stiff knee gait is a frequent condition among stroke patients leading to reduce gait speed and increase energy cost. In association with neuro-rehabilitation, botulinum toxin A injections in the rectus femoris is recommended. Read more about this study

About this study

Official title: A Randomized Controlled Trial of Rectus Femoris Tenotomy Versus Botulinum Toxin A for Stiff Knee Gait After Stroke

Stiff knee gait is defined as the lack of knee flexion in the swing phase of gait. Stiff knee gait is a frequent condition among stroke patients leading to reduce gait speed and increase energy cost. In association with neuro-rehabilitation, botulinum toxin A injections in the rectus femoris is recommended. However, the botulinum toxin A effect is transient necessitating repeated injections.

The aim of this study is to compare the benefit of the rectus femoris tenotomy in comparison with botulinum toxin A injections according to the 3 domains of the International Classification of Functioning Disability and Health of the World Health Organisation

Read the detailed description

INTRODUCTION

Stroke is the third cause of death and the leading cause of handicap among industrialized countries. Spasticity and co-contraction of the rectus femoris muscle following stroke is responsible for a lack of knee flexion in the swing phase of gait named stiff knee gait.

The rectus femoris spasticity is usually treated by oral medications, physical therapy and botulinum toxin A injections (1,2). As botulinum toxin A has a transient effect, injections must be repeated supporting to promote a permanent surgical treatment such as the rectus femoris tenotomy (3). However, no study has evaluate neither compare the effect of the rectus femoris tenotomy on gait and on the 3 domains of the International Classification of Functioning Disability and Health .

OBJECTIVE

To compare the effect of the rectus femoris tenotomy and of the botulinum toxin A injections for stiff knee gait after stroke according to the 3 domains of the International Classification of Functioning Disability and Health

METHODS

The investigators will recruited 20 chronic stroke patients presenting with stiff knee gait. The patients will be randomly assigned to a surgical group treated by rectus femoris tenotomy (10 patients) and to a medical group treated by rectus femoris botulinum toxin A injections.

Patients will be assessed before treatment, 2 months and 6 months after treatment by an assessor blinded therapist among the 3 domains of the International Classification of Functioning Disability and Health

PERSPECTIVE

The investigator hope to demonstrate the effectiveness of the rectus femoris tenotomy as a treatment of stiff knee gait after stroke

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Tenotomy of the proximal rectus femoris tendon and Botulinum Toxin injection in the rectus femoris muscle in people with Stroke and Spasticity, run by University Hospital of Mont-Godinne at 1 site in Belgium.

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 6 inclusion and 3 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: status not confirmed, as of the sponsor's last update on 15 Apr 2014. 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 Belgium. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

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

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Ashworth scale at the rectus femoris (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02114736, which also lists 3 linked publications.

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 15 Apr 2014.
