Turning-based treadmill training improves turning performance and gait symmetry after stroke

Area of Science:

• Neurorehabilitation
• Movement Science
• Physical Therapy

Background:

• Turning is a complex motor task that is frequently impaired after stroke.
• Effective rehabilitation programs specifically targeting turning deficits in chronic stroke patients are lacking.

Purpose of the Study:

• To investigate the efficacy of a novel turning-based treadmill training program.
• To assess the impact of this training on turning performance, gait symmetry, balance, and muscle strength in individuals with chronic stroke.

Main Methods:

• Thirty chronic stroke participants were randomized into either a turning-based treadmill training group or a regular treadmill training control group.
• Both groups underwent 12 sessions over 4 weeks, followed by a 10-minute general exercise program.
• Outcomes including turning speed, gait characteristics, balance, and muscle strength were measured at baseline, post-intervention, and at 1-month follow-up.

Main Results:

• The turning-based treadmill training group demonstrated significant improvements in turning speed, straight-walking performance (speed and symmetry), hip flexor and ankle dorsiflexor strength, and balance control compared to the control group.
• These improvements were observed regardless of stroke type (ischemic or hemorrhagic).
• The enhanced outcomes were sustained at the 1-month follow-up assessment.

Conclusions:

• Turning-based treadmill training is a feasible and effective intervention for improving turning ability in chronic stroke survivors.
• This training approach also enhances gait symmetry, muscle strength, and balance control.
• The sustained improvements suggest long-term benefits for functional recovery after stroke.
