ICF- Based Home O ccupational Therapy f or S evere Traumatic B rain Injury: A Case Study on Its Effects

Objective : This study aimed to investigate the therapeutic efficacy of home-based occupational therapy interventions grounded in the International Classification of Functioning, Disability and Health (ICF) framework on functional independence in activities of daily living (ADLs), fall frequency reduction, and enhancement of social participation in an individual with severe traumatic brain injury (TBI). Methods : A single-subject case study design was employed involving a patient diagnosed with severe TBI. Sixteen sessions of ICF-oriented home occupational therapy were administered biweekly over an eight-month period. Pre- and post-intervention assessments were conducted using both quantitative and qualitative methodologies to examine changes in ADL performance, fall incidence, and levels of social engagement. Results : Post-intervention analysis revealed a 41.67% improvement in ADL performance. The monthly average fall rate significantly decreased from 3.0 to 0.5. Additionally, the participant demonstrated meaningful reintegration into community life, participating in local gatherings and outdoor activities with the assistance of a personal care aide. Conclusion : Findings from this case study underscore the potential clinical utility of ICF-based home occupational therapy in promoting functional recovery, mitigating fall risks, and fostering social reintegration in individuals with severe TBI. Although the single-case methodology limits generalizability, the outcomes suggest promising directions for future large-scale, longitudinal investigations.
