Effectiveness of Endurance Exercise Training to Improve Economy of Movement in People with Parkinson Disease: A Case Report
By Das S, Islam SKS, Mondal S
Background: Parkinson disease (PD) is a progressive neurodegenerative disorder characterized by motor impairments including bradykinesia, rigidity, tremor, and postural instability. These impairments negatively affect gait efficiency and increase the energy cost of movement, leading to early fatigue and reduced participation in daily activities. Impaired economy of movement is a significant contributor to functional decline in people with PD. Endurance exercise training has been shown to improve cardiovascular fitness and neuromuscular efficiency in various neurological and musculoskeletal conditions. However, limited case-based evidence is available regarding its specific effects on movement economy in individuals with Parkinson disease. Objective: The objective of this case report was to evaluate the effects of a structured endurance exercise training program on economy of movement, gait efficiency, and functional mobility in a person with Parkinson disease. Case Presentation: The case involved a 62-year-old individual diagnosed with idiopathic Parkinson disease at Hoehn and Yahr stage II. The participant underwent an eight-week endurance exercise training program consisting of moderate-intensity aerobic activities, including treadmill walking and stationary cycling, performed four times per week. Exercise intensity was prescribed using heart rate reserve and the Borg Rating of Perceived Exertion scale. Outcome measures included economy of movement assessed by oxygen consumption during submaximal walking, gait parameters, walking endurance, and selfreported fatigue. Assessments were conducted at baseline and following completion of the intervention. Results: Following the endurance training program, the participant demonstrated improved economy of movement, indicated by reduced oxygen consumption at equivalent walking speeds. Improvements were also observed in gait efficiency, walking endurance, and functional mobility. The participant reported decreased fatigue during daily activities. No adverse events or exercise related complications were reported. Conclusion: This case report suggests that endurance exercise training may be a safe and effective intervention for improving economy of movement and functional performance in individuals with Parkinson disease. Larger studies are warranted to confirm these findings and guide clinical practice.
