Summary of article contents:
Introduction
Stroke survivors often face significant challenges in mobility, particularly regarding walking and balance. This difficulty is compounded for individuals suffering from diabetic peripheral neuropathy (DPN), a condition that leads to sensory loss and increased risk of falls. The present study aims to explore the impact of dual tasking—performing cognitive or motor tasks while moving—on the gait and turning performance of stroke survivors both with and without DPN. The goal is to understand how these additional cognitive demands affect their mobility.
Impact of Dual Tasking on Gait Performance
The study's findings reveal that dual tasking significantly impairs gait and turning performance among stroke survivors, particularly those with DPN. Participants undergoing timed up and go (iTUG) tests showed increased completion times and notable reductions in spatiotemporal gait parameters under dual cognitive tasks compared to single-task conditions. Stroke survivors with DPN were found to experience heightened difficulties, demonstrating longer times for completing the test and reduced stride velocities and lengths. This indicates that cognitive workload plays a critical role in the mobility of these patients, underscoring the connection between cognitive function and physical performance during daily activities.
Conclusion
In conclusion, the study highlights the essential relationship between cognitive functioning and gait performance, particularly for stroke survivors with DPN. As dual tasking significantly affects their mobility, incorporating cognitive challenges into rehabilitation might be beneficial. By addressing the cerebral and physical aspects of mobility simultaneously, targeted dual-task training strategies may help mitigate fall risks and improve overall functional outcomes for stroke survivors with DPN. Further research is encouraged to assess the long-term impacts of dual-task training on gait performance and fall history among this vulnerable population.
