What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tested a thin, pressure-sensing tube placed in the throat to measure swallowing in people with difficulty swallowing (dysphagia). Researchers followed 4 participants as they underwent standard swallowing therapy, comparing results to healthy controls. The goal was to see if these pressure measurements could predict who will improve with treatment.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could lead to better ways to measure and predict who will benefit from swallowing therapy.
What could go wrong
This is a very small, early study with only 4 participants, so results may not apply to everyone with dysphagia.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

300 adults will be recruited to participate in the study. Participants will include 250 patients with heterogeneous causes of dysphagia undergoing active swallowing treatment and 50 age- and sex-match control participants with healthy swallow function. Participants will be stratified into the following goals of swallowing rehabilitation: Group A) Pharyngeal strengthening (n=125); and Group B) Relief of upper esophageal sphincter (UES) dysfunction or pharyngeal outlet obstruction (n=125). Classification will be based on clinician-driven diagnoses and treatment goals based on standard of care evaluation. The control group of healthy individuals will be Group C (n=50). Participants' age may range from 18-99 years old; as dysphagia is more frequent in the elderly, the sample will most likely include individuals age 60 and over.

Inclusion Criteria: * Pathological Group * Must have dysphagia as diagnosed by a licensed and certified otolaryngologist, gastroenterologist, or speech-language pathologist AND must have a dysphagia treatment plan that includes one of the following primary goals: * Therapy to strengthen oropharyngeal musculature * Medical or surgical management to relieve an obstruction at the upper esophageal sphincter * Must agree to comply with swallowing assessment, including interview and manometry * Must sign the Informed Consent form approved by the Health Sciences Institutional Review Board of the University of Wisconsin * Normal Group * Having no swallowing disorders * Must agree to comply with swallowing assessment, including interview and manometry * Must sign the Informed Consent form approved by the Health Sciences Institutional Review Board of the University of Wisconsin.\\ Exclusion Criteria: * Pathological Group * Therapeutic management plan already initiated prior to recruitment * Therapy goals including only improvement of swallowing coordination * Developmental disability, dementia, cognitive dysfunction, or difficulty comprehending instructions * Positive history of allergic response to topical anesthetic * Allergy to food relevant to study participation (e.g. lactose intolerance) * Normal Group * Known swallowing disorder * Developmental disability, dementia, cognitive dysfunction, or difficulty comprehending instructions * Positive history of allergic response to topical anesthetic * Allergy to food relevant to study participation (e.g. lactose intolerance)
