About this study

Official title: Acute Stroke Patients With Dysphagia After Different Swallowing Therapies: Videofluoroscopy Findings and Brain Plasticity in Magnetic Resonance Imaging

Dysphagia after stroke is associated to increased pulmonary complications and mortality. The swallowing therapies could decrease the pulmonary complications and improve the quality of life after stroke. The swallowing therapies include dietary modifications, thermal stimulation, compensatory positions, and oropharyngeal muscle stimulation. Most researchers used clinical assessments and videofluoroscopy to evaluate the effect of the swallowing therapies. Some authors performed functional magnetic resonance imaging (fMRI) to investigate the brain neuroactivity during swallowing with tasks in normal adults and unilateral hemispheric stroke patients. The aim of this study is to explore the effect of swallowing therapies not only in clinical swallowing function but also brain plasticity of acute stroke patients with dysphagia by videofluoroscopy and fMRI.

Read the detailed description

In the study, 10 healthy controls and 48 patients with a single and acute hemispheric or brain stem stroke will be enrolled. Both 24 hemispheric and 24 brain stem stroke patients will be divided into 3 groups. General swallowing therapy, oropharyngeal neuromuscular electrical stimulation (NMES), and combined general and NMES therapies will be randomly provided for the 3 groups. Each patient will receive clinical assessment of food oral intake scale, functional dysphagia scale of videofluoroscopy, and brain neuroactivity in fMRI.

The investigators hope to find the benefit of the swallowing therapies both in clinical swallowing function and in brain functional neuroactivity/reorganization after acute stroke. While comparing the 3 swallowing therapies, different functional neuroactivity may be facilitated by different swallowing therapies. Finally, the investigators could also find out the most effective swallowing therapy among the 3 therapies in acute stroke patients with dysphagia according to the findings of videofluoroscopy and fMRI.

What participants receive

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

  • general swallowing therapyOther

    including a session of oral exercises, tactile stimulation, compensatory techniques, swallowing maneuvers that are taught to the participants by a speech therapist.

  • NMES therapyOther

    he NMES therapy with VitalStim therapeutic device will be done by one physician who is licensed practitioner and certified in use of the VitalStim device. The placement of 2-channel electrodes is depended on the dysphagic types and the findings on VFS.

What is being measured

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

  1. The functional oral intake scale

    Clinical swallowing evaluations: The functional oral intake scale (FOIS) was reported by Crary et al. for presenting the functional oral intake of food and liquid in stroke patients. One physician who is blinded to the therapies will evaluate the FOIS for each participant before and after swallowing treatments.

    Measured: baseline (before intervention), changes from baseline FOIS at 4 weeks

Secondary outcomes (5)
  1. 8-point penetration-aspiration scale (PAS)

    VFS is a standard tool for swallowing disorders. A 8-point penetration-aspiration scale (PAS) is used for observing the event of penetration or aspiration on VFS.

    Measured: baseline (before intervention), changes from baseline PAS score at 4 weeks

  2. 11-item functional dysphagia scale (FDS)

    A 11-item functional dysphagia scale (FDS) of VFS is a sensitive and specific method for quantifying swallowing function in stroke.

    Measured: baseline (before intervention), changes from baseline FDS score at 4weeks

  3. 3-Dimensional (3D) structural MRI

    MR images are obtained using a 3.0-T whole body magnet with a 50- and 23-mT/m gradient strength, and an echo-planar-capable receiver (GE SIGNA EXCITE HD, GE Medical Systems, Milwaukee, US).

    A 3-dimensional (3D) structural MRI is acquired for each subject using a T1-weighted gradient echo magnetization prepared rapid gradient echo sequence yielding 124 sagittal slices with a defined voxel size of 1 x 1 x 1.5 mm.

    Measured: baseline (before intervention), changes from baseline result of 3-Dimensional (3D) structural MRI at 4 weeks

  4. Function MRI

    MR images are obtained using a 3.0-T whole body magnet with a 50- and 23-mT/m gradient strength, and an echo-planar-capable receiver (GE SIGNA EXCITE HD, GE Medical Systems, Milwaukee, US).

    The functional images are obtained using an EPI sequence with the following parameters: 33 axial slices, image resolution = 3.75*3.75*4, and TR= 2000 ms.

    Measured: baseline (before intervention), changes from baseline result of fMRI at 4 weeks

  5. Diffusion tensor imaging

    MR images are obtained using a 3.0-T whole body magnet with a 50- and 23-mT/m gradient strength, and an echo-planar-capable receiver (GE SIGNA EXCITE HD, GE Medical Systems, Milwaukee, US).

    An 8 channels diffusion tensor imaging (DTI) acquisition protocol will be used to acquire high resolution DTI, i.e. 2 x 2 x 2 mm3 voxel size. With 13 diffusion encoding directions and number of average of 4, whole brain DTI and high resolution eigenvector field can be acquired within 20 mins.

    Measured: baseline (before intervention), changes from baseline result of diffusion tensor imaging at 4 weeks

The record says: finished, as of the sponsor's last update on 9 Feb 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

The functional oral intake scale (time frame: baseline (before intervention), changes from baseline FOIS at 4 weeks). 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 NCT03048916, which also lists 35 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 9 Feb 2017; AzTrials last refreshed its copy on 31 Oct 2026.
