Effectiveness of Task-Oriented Training in Improving Functional Independence in Elderly Stroke Survivors

Abstract

Background: Stroke is a leading cause of long-term disability in the elderly, often resulting in reduced functional independence and diminished quality of life. Traditional impairment-based rehabilitation may not always translate into meaningful daily function. Task-Oriented Training (TOT) emphasizes repetitive, purposeful practice of real-life tasks, aiming to enhance neuroplasticity, motor learning, and independence. Objective: To synthesize current evidence (2015–2025) on the effectiveness of TOT in improving functional independence among elderly stroke survivors, with particular attention to intervention characteristics, delivery modes, and emerging trends. Methods: A narrative review approach was adopted. Literature was searched in PubMed, Scopus, and the Cochrane Library using keywords including “Task-Oriented Training,” “stroke,” “elderly,” and “functional independence.” Randomized controlled trials and cohort studies involving participants aged ≥60 years were included if they reported outcomes using validated measures such as the Functional Independence Measure (FIM) or Modified Barthel Index (MBI). Data were synthesized thematically rather than pooled statistically. Results: Twelve studies met the inclusion criteria, encompassing 1,200 elderly participants. TOT consistently improved functional independence, particularly in upper-limb and hand function, with interventions lasting six to eight weeks producing the greatest gains. Benefits were observed across therapist-led and technology-assisted formats. Thematic analysis identified key factors influencing effectiveness: functional relevance of tasks, adequate training intensity, and progressive complexity. Limitations across the literature included protocol heterogeneity, varied outcome measures, small sample sizes, and limited long-term follow-up. Conclusion: TOT is an effective, adaptable, and patient-centered approach for enhancing functional independence in elderly stroke survivors. Programs of six to eight weeks, focused on meaningful upper-limb tasks, offer the most pronounced benefits. Future research should prioritize standardized protocols, core outcome measures, and long-term sustainability assessments.
