Intensive Individualized Recovery in Chronic Post-stroke Disability: Functional Outcomes, Fatigue Modulation, and Implications for Extended Neuroplasticity

Chronic post-stroke disability is commonly associated with limited recovery potential, often due to insufficient intensity and duration of conventional interventions. Emerging evidence suggests that neuroplasticity may persist beyond traditional recovery windows when interventions are appropriately intensified, individualized, and grounded in exercise physiology principles. This study aimed to evaluate functional recovery outcomes following an intensive, individualized recovery-oriented program in a patient with severe chronic post-stroke impairment and to explore the role of fatigue in modulating performance and adaptation. A single-case clinical study was conducted in a patient with long-standing post-stroke disability and minimal prior improvement. The intervention consisted of prolonged, high-dose daily recovery sessions incorporating task-specific training, neuromuscular re-education, endurance conditioning, and continuous real-time adaptation based on fatigue and performance. Clinical observations were supplemented with an illustrative dataset to model longitudinal trends and functional relationships. The patient demonstrated progressive improvements in mobility, balance, coordination, endurance, and independence in activities of daily living. Recovery tolerance and training capacity increased over time, enabling longer and more effective sessions. Longitudinal analysis indicated consistent functional gains and a negative association between fatigue and performance, suggesting that fatigue modulation may play a key role in optimizing recovery outcomes. This case supports the potential for meaningful functional recovery in chronic post-stroke populations through high-intensity, individualized, exercise physiology-based recovery strategies. The findings highlight the importance of intervention dose, adaptive programming, and fatigue management and suggest that recovery capacity may extend beyond conventional expectations. Further research using standardized outcome measures is warranted.
