Web-based Oral Reading for Language in Aphasia (Web ORLA^®): A pilot randomized control trial

Area of Science:

• Neurology
• Speech-Language Pathology
• Rehabilitation Medicine

Background:

• Aphasia, a language disorder resulting from brain damage, significantly impacts communication.
• Traditional aphasia therapies often require intensive in-person sessions, posing accessibility challenges.
• Remote, computer-based interventions offer a potential solution for delivering therapy to individuals with chronic aphasia.

Purpose of the Study:

• To evaluate the efficacy of an intensive, asynchronous, computer-based treatment for aphasia delivered remotely.
• To investigate the use of Web ORLA (Oral Reading for Language in Aphasia) with clinician oversight.
• To assess long-term language improvements following the intervention.

Main Methods:

• A single-blind, randomized placebo-controlled trial was conducted with adults having chronic aphasia.
• Participants engaged in either Web ORLA therapy or a computer game placebo for six weeks, 90 minutes daily.
• Language Quotient changes were measured using the Western Aphasia Battery-Revised pre-treatment, post-treatment, and at six-week follow-up.

Main Results:

• Web ORLA treatment led to significant immediate post-treatment language improvements.
• While no immediate difference was seen compared to placebo, the Web ORLA group showed significantly greater language gains at the six-week follow-up.
• The intensive, remotely delivered therapy demonstrated sustained positive effects on language performance.

Conclusions:

• Intensive, web-based ORLA therapy is effective for improving language outcomes in individuals with chronic aphasia.
• Combining clinician oversight with flexible, asynchronous practice enhances treatment delivery and efficacy.
• This approach offers a valuable, accessible option for aphasia rehabilitation.
