Trial summary

Amyotrophic lateral sclerosis (ALS) is characterized clinically by abnormalities of both upper motor neurons (UMN) and lower motor neurons (LMN). The presence of UMN signs is not always easy to establish. Read more about this study

About this study

Amyotrophic lateral sclerosis (ALS) is characterized clinically by abnormalities of both upper motor neurons (UMN) and lower motor neurons (LMN). The presence of UMN signs is not always easy to establish. The only technique used in routine to assess the corticospinal dysfunctions is based on transcranial magnetic stimulation (TMS). However, this technique is largely dependent on LMN state and is based on artificial motor cortex activation.

The main objective of our study project is to evaluate a new method assessing functional changes in motor system in ALS patients. By using cortico-muscular and cortico-cortical coherences, it could be possible to show modifications in both cortico-muscular relationship and in cortical activity coordination which could be related to clinical state in ALS patients. We notably expect a decrease in cortico-muscular coherence in ALS patients. Furthermore, these analyses could provide new insights in motor system plasticity phenomena. We expect a partial covering of voluntary motor command by cortical areas adjacent to primary motor cortex. Lastly, the hypothesis that an increased proportion of voluntary motor control may be assumed by ipsilateral corticospinal tract could be tested by coherence analyses.

Coherence analysis might be a useful method to detect corticospinal tract dysfunctions. This method has the advantage to be painless and not to use artificial stimulations as it is used in TMS.

What is being measured

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

  1. recording neuronal activities

    simultaneous recording of brain activity using electrodes attached to the scalp and muscle activities of muscles of the hands with electrodes bonded to the skin.

    Measured: 12 months

Secondary outcomes (1)
  1. identify plasticity phenomena

    identify plasticity phenomena used in the cortex during the disease. The question is whether a reorganization of cortical networks could preserve, temporarily, the ability of patients to perform muscle contractions which case to determine the nature of the changes induced

    Measured: 12 months

Questions about this trial

What is this clinical trial studying?

A study testing electroencephalograms (EEG) and electro-myography (EMG) in people with Amyotrophic Lateral Sclerosis, 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 9 inclusion and 13 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: paused, as of the sponsor's last update on 24 Aug 2015. 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?

Results are not available in the source record.

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?

recording neuronal activities (time frame: 12 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 24 Aug 2015.
