About this study
Official title: Comparison of Therapeutic Effect and Brain Activity According to Language Rehabilitation Program and Language Therapy in Patients With Speech Impairment After Stroke. Prospective, Randomized, Single-blind, Exploratory Clinical Study
Our study will provide precise and intensive speech rehabilitation treatment program to patients with speech disorders after stroke, and compare clinical evaluations with the conventional speech therapy patient group.
Clinical evaluation tools will be performed before and after the treatment for all patients
- K-Western Aphasia Battery for aphasia assessment tools
- Cerebral blood flow changes with near-infrared spectroscopy
Read the detailed description
During the initial evaluation of this study, the patient's gender, age, and onset of stroke lesion occurrence are collected and a cognitive evaluation is performed. In addition, the K-Western Aphasia Battery for aphasia assessment tools(K-WAB) and Cerebral blood flow changes with near-infrared spectroscopy will be performed. All participants will be assigned to a test group or control group. In addition to the existing speech rehabilitation treatment, the test group will receive a speech rehabilitation program, and the control group will receive the same treatment as the existing speech rehabilitation treatment.
After treatment is completed, the K-WAB test and near-infrared spectroscopy will be performed again.

Zenicog;language rehabilitation programDevice
This program is an AI-based computerized cognitive and language training program.
Conventional language rehabilitationProcedure or surgery
Conventional language rahabilitation therapy will apply for all participants with speech impairement
| Study group | Role | What they receive |
|---|---|---|
| Language therapy group with language rehabilitation program | Experimental | In addition to 5-session conventional language therapy, we provide a 5-session language rehabilitation program using an AI-based computerized cognitive and language training program. A cognitive evaluation is conducted before starting treatment, and K-Western Aphasia Battery and Functional Near infrared spectroscopy are performed before and after the treatment. Receives: Device: Zenicog;language rehabilitation program; Procedure: Conventional language rehabilitation |
| Conventional language therapy group | Active comparator | We provide a 10-session conventional language therapy. A cognitive evaluation is conducted before starting treatment, and K-Western Aphasia Battery and Functional Near infrared spectroscopy are performed before and after the treatment. Receives: Procedure: Conventional language rehabilitation |
