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 Results may not be published yet.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

Summary

This study looked at how children with and without hearing loss use eye gaze and facial expressions to improve speechreading (lip-reading). Researchers tested 140 children aged 8–11 with cognitive and speechreading tasks, and some children with hearing loss trained using a special app called Optic Track. The goal was to find which gaze patterns and background factors lead to the best speechreading results.

What this could mean

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

Active substance
Speechreading training application (Optic Track)
What this could lead to
If successful, this could point toward better speechreading training tools for children with hearing loss, potentially improving communication and social interaction.
What could go wrong
This is a small, completed observational and behavioral study, not a treatment trial. Results may not apply broadly, and the app's real-world benefit remains unproven.

Inclusion Criteria: Normally hearing children: * age 8-11 years * being born full-term (on 37. gestational week or later) * Finnish speaking (Finnish is the language the child's family uses at home, the child goes to a school where Finnish is used as the language of instruction) * normal hearing and vision * typically developing, mainstream education curriculum at school * for those tested remotely: computer available at home for remote testing Children with hearing impairment/loss: * age 8-11 years * diagnosed bilateral hearing impairment * being born full-term (on 37. gestational week or later) * Finnish speaking (Finnish is the language the child's family uses at home, the child goes to a school where Finnish is used as the language of instruction) * normal vision * (mainly) typically developing * for those tested remotely: computer available at home for remote testing Exclusion Criteria: Normally hearing children: psychiatric and neurodevelopmental disorders, including ADHD (Attention Deficit and Hyperacitivity Disorder) Children with hearing impairment/loss: psychiatric and neurodevelopmental disorders (excluding ADHD if medication helps the child to concentrate well during testing)
