Trial summary

In individuals with spino-cerebellar atrophy (SCA), the delayed onset of antagonist muscle firing has been reported to be the cause of hypermetria. Hypermetria is a common deficit in individuals with spino-cerebellar atrophy SCA when they perform ballistic goal-directed movement. Read more about this study

About this study

In individuals with spino-cerebellar atrophy (SCA), the delayed onset of antagonist muscle firing has been reported to be the cause of hypermetria. Hypermetria is a common deficit in individuals with spino-cerebellar atrophy SCA when they perform ballistic goal-directed movement. Based on the previous studies, ballistic goal-directed movements are controlled by a triphasic pattern of agonistic and antagonistic muscle activation. The origin of the EMG pattern is a central program, whereas the delayed onset of antagonistic muscle firing has been reported to be the cause of hypermetria. To develop a therapy method, the difference in temporal pattern and intensity of supraspinal excitability of agonist and antagonist bursts between healthy adults and individuals with SCA when performing rapid and slow goal-directed movements should be further investigated.

Traditional rehabilitations of individuals with cerebellum lesion were limited to improve the functional performance of movement. Since the deficits of the goal-directed movement are at pre-movement programming, only feedforward training will be possible to re-establish an appropriate program.

Previous showed that peripheral stimulation resulted in a facilitation of motor cortex. Our group also found that this facilitation in individuals with SCA was similar to the ones without SCA. Therefore, it is possible to adjust the control pattern of supraspinal excitability of agonist and antagonist busts of SCA patient with passively providing electrical stimulation contains normal control pattern of healthy human.

The present study sought to investigate the difference in temporal pattern and intensity of supraspinal excitability of agonist and antagonist bursts between healthy adults and individuals with SCA when performing rapid and slow goal-directed movements.

What is being measured

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

  1. Muscle evoked potential(MEP)

    Measure of changes in MEP of flexor carpi radialis.

    Measured: Baseline, 4 weeks.

  2. Electromyography(EMG)

    Measure of changes in EMG of flexor carpi radialis and extensor carpi radialis.

    Measured: Baseline, 4 weeks

  3. Movement error

    Measure of changes in movement error during fast 30 degrees wrist extensions.

    Measured: Baseline, 4weeks

Questions about this trial

What is this clinical trial studying?

A study testing Temporal electrical stimulation in people with Spinocerebellar Atrophy (SCA), run by Chang Gung University at 1 site in Taiwan.

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 1 inclusion and 0 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 Nov 2013. 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 Taiwan. 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?

Muscle evoked potential(MEP) (time frame: Baseline, 4 weeks.). The study lists 3 primary outcomes in all. 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 NCT01983670, which also lists 1 linked publication.

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 Nov 2013.
