COMPARISON OF SEMANTIC FEATURE ANALYSIS (SFA) AND MELODIC INTONATION THERAPY (MIT) IN PATIENTS WITH NON-FLUENT APHASIA

Abstract

Introduction: Individuals with aphasia often experience difficulties in naming objects and words. While there have been reports of treatment benefits from approaches like Semantic Feature Analysis (SFA) and Melodic Intonation Therapy (MIT), a comprehensive understanding of their effectiveness is lacking. This study seeks to address this gap by investigating whether the therapeutic impact of SFA and MIT varies among individuals with Non-Fluent Aphasia. The primary objective of the research is to compare the outcomes of these therapy protocols to gain insights into their relative effectiveness.

Methods: The research was structured as a Between Group Research design, employing a non-randomized control sampling strategy to assess the effectiveness of Semantic Feature Analysis (SFA) and Melodic Intonation Therapy (MIT) in treating patients with Non-Fluent Aphasia. Utilizing a Within Subject Research Design, pre and post assessments were conducted. Data was gathered through purposive sampling from hospital settings, involving a sample size of 10 participants. Comprehensive assessment tools including the Boston Diagnostic Aphasia Examination, Progressive, and Aphasia Severity Scale were administered both before and after therapy sessions, spanning 6-8 weeks, conducted 2-3 days a week, each lasting 30-45 minutes.

Results: The Wilcoxon Signed Ranked Test showed good posttest findings, whereas the Mann-Whitney U Test produced favorable results, indicating a beneficial outcome. This study provides tried-and-true procedures to manage language impairments in people with aphasia, and it is anticipated to have a substantial positive impact on speech-language pathologists working in actual clinical settings.
