Effectiveness of Task-Oriented Circuit Training in Improving Functional Mobility and Balance in Moderate Parkinson’s Disease: A Case Study

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by motor impairments that significantly affect mobility and daily activities. This case study explores the effectiveness of task-oriented circuit training (TOCT-AT) in improving functional mobility, balance, and independence in a 60-year-old woman with moderate PD (Modified Hoehn & Yahr Stage 3). The subject, who experienced frequent falls and gait instability, underwent a 12-week personalized training program focusing on task-specific motor activities, gait retraining, and sensory-modulated exercises. Outcome measures included the Timed Up and Go (TUG) test, Modified Dynamic Gait Index (m-DGI), and Functional Independence Measure (FIM), assessed at baseline, 6 weeks, and 12 weeks. Results showed a significant reduction in TUG time (32 ± 2s to 18 ± 1.8s), an increase in m-DGI score (32 to 50), and improved FIM scores (98 to 107), exceeding Minimal Clinically Important Difference (MCID) values. The improvements in gait adaptability, postural control, and fall risk reduction suggest that TOCT-AT is a clinically relevant approach for enhancing mobility in PD. This study highlights the potential of personalized, task-based rehabilitation in improving functional outcomes in PD and encourages further research to establish long-term benefits.
