Case Study of a 75-Year-Old Woman with Parkinson's Disease: Rehabilitation Trajectory with Logic Workout Training

Abstract: We report the single-case trajectory of a 75-year-old retired occupational female therapist with idiopathic Parkinson's disease, Hoehn and Yahr stage 2 at diagnosis. Following progressive impairment despite standard care, she initiated training with Logic Workout (LW) in July 2025 under supervision. Within weeks, she reported meaningful improvements spanning motor function, posture, pain, fine motor skill, mood, sleep consolidation, and disappearing of fatigue. Although single cases cannot establish generalizable efficacy, systematic and chronological documentation can be valuable for hypothesis generation and feasibility assessment in real-world settings prior to controlled trials. We summarize the baseline condition and treatment history, describe the LW intervention, compile self-reported outcomes, and interpret the findings in light of the underlying Logic Workout hypothesis, before concluding with key caveats and perspectives for future research.
