University of Alberta researchers are using a video technique to treat stuttering.

Video self-modelling, or VSM, is a technique used for learning new abilities. Those who practice VSM record themselves performing an action successfully, and then watch the video repeatedly to master the new skill.

The technique is often used by athletes looking to improve their form or learn new moves. It's also been used to treat Tourette syndrome and improve communication skills for children with autism.

Researchers from the University of Alberta’s Institute for Stuttering Treatment and Research conducted the study with the help of clients who had undergone speech therapy at the institute.

According to the study’s authors, people who stutter typically fall back into old speech patterns after completing traditional treatment.

"It's hard to keep the motivation going,” Marilyn Langevin, the institute’s director of research, said in a statement on Friday.

That’s where video self-modelling comes in.

For the pilot study, researchers had clients who underwent successful therapy record themselves speaking fluently. Clients were then required to continue watching the video twice a week after therapy had ended.

Researchers found the self-modelling videos helped clients remain on-track with their fluency.

Clients who watched their videos more than the recommended twice-a-week also reported fewer instances of stuttering.

“Video self-modelling helps clients see themselves perform the behaviour in a very confident, successful way," Langevin said. "It builds their belief and their ability to do it and helps with motivation."

One of the study participants, Tom Sesink, said in the statement that the treatment improved both his speech and his self-image.

Sesink said he still stutters sometimes, especially when he’s tired, stressed or in a large crowd. But he's now more comfortable with his speaking abilities.
