Abstract
<p>Background: Contemporary core occupational therapy models focus heavily on the psychosocial, motivational, and contextual dimensions of human occupation. However, the current literature lacks robust conceptual tools for the micro-analysis of technical efficiency, execution purity, and energy or cognitive conservation across various occupational domains.Objective: This paper introduces the Miller Praxiological Model of Occupational Therapy (MPMOT), which translates the foundational concepts of Tadeusz Kotarbiński’s Polish school of praxiology into modern rehabilitation, clinical assessment, and adult neurocognitive education.Methods: The framework redefines the individual as an active agent/patient and structures the therapeutic process around the systematic mastery of efficient action. The model operationalizes three core pillars: effectiveness, economy of effort, and action purity, guided ethically by the concept of the trustworthy caregiver (opiekun spolegliwy). To measure these constructs, a new standardized diagnostic tool, the Miller Action Performance Scale (MAPS), is introduced. The model's clinical utility was validated through a retrospective case series analysis of five anonymized records spanning paediatric neurology, neurodevelopmental dyspraxia, geriatrics, isolated biomechanical injuries, and adult ADHD.Results: Retrospective data demonstrate that implementing the MPMOT successfully isolates and resolves critical procedural and technical barriers in both physical and digital workflows. Over a 3-to-5-week intervention period, targeted praxiological training resulted in significant functional improvements, with average quantitative MAPS metrics shifting from critical action deficits (8–12 points) to high praxiological efficiency (20–23 points out of a maximum of 25).Conclusions: The Miller Model shifts the rehabilitation paradigm from merely encouraging an agent/patient to act, to systemically engineering how they act, establishing technical precision and behavioural harmony as catalysts for autonomy and dignity.Keywords: Miller Model; MPMOT; occupational therapy; praxiology; Tadeusz Kotarbiński;efficient action; economy of effort; executive dysfunctionSR=treszczenieWnioski: Model Miller zmienia paradygmat rehabilitacji: zamiast jedynie zachęcać sprawcę/pacjenta do działania, systemowo projektuje sposób jego wykonania. Przekształcając podopiecznych w autonomicznych wykonawców sprawnego działania, model ten udowadnia swoją wysoką użyteczność jako czułe narzędzie diagnostyczne oraz metoda przywracania niezależności i godności.Słowa kluczowe: Model Miller; MPMOT; terapia zajęciowa; prakseologia; Tadeusz Kotarbiński; sprawne działanie; gospodarność; dysfunkcje wykonawcze</p>
