Effects of single- and dual-task training on dual-task walking performance, prosthetic-limb dynamics and quality of life in unilateral transtibial amputees.

Introduction: The aim of the study was to compare the effects of single-task versus dual-task training on dual-task walking performance, prosthetic-limb kinematics, centre-of-pressure behaviour, and health-related quality of life in adults with transtibial amputation. Methods: Forty-five participants undertook an eight-week intervention and were randomly allocated to one of three groups: control, single-task training, or dual-task training. Gait variables were obtained from 3D motion capture and force-plate analysis, while health-related quality of life was assessed using a composite measure derived from the WHOQOL-BREF. Results: Two-way mixed ANOVA showed that both single-task and dual-task training produced significant improvements in dual-task walk-performance time compared with the control group ( Discussion: These findings indicate that an eight-week programme of single- or dual-task training improves walking capability in individuals with transtibial amputation, reflective in improved gait automaticity and more stable, efficient centre-of-pressure transitions from foot strike to push-off in the affected limb. Dual-task training provides additional benefit, producing greater gains across all gait variables and resulting in a significant improvement in perceived quality of life. Future research should examine the long-term transfer of cognitive-motor training to real-world mobility and participation outcomes.
