Motion controlled gait enhancing mobile shoe for rehabilitation

Area of Science:

• Neurorehabilitation
• Biomechanics
• Assistive Technology

Background:

• Split-belt treadmill training improves post-stroke walking but offers temporary benefits.
• Current methods lack long-term retention of gait improvements during over-ground walking.

Purpose of the Study:

• To develop and assess a mobile device for simulating split-belt treadmill gait alterations during natural walking.
• To investigate the potential for longer-lasting gait improvements through over-ground training.

Main Methods:

• Development of a portable, motion-controlled gait enhancing mobile shoe (GEMS).
• Utilizes an Archimedean spiral wheel to convert downward force into horizontal backward motion.
• Passive design regulated by a magnetic particle brake, with on-board electronics for continuous, smooth motion.

Main Results:

• The new GEMS design addresses drawbacks of previous versions, offering continuous and regulated motion.
• The passive, motor-less design effectively redirects forces for gait alteration.
• Further experimentation is required to validate long-term after-effects.

Conclusions:

• The developed mobile gait enhancing shoe offers a promising approach for sustained gait rehabilitation.
• Over-ground training with this device may lead to more durable improvements in walking patterns post-stroke.
• Long-term efficacy requires further investigation.
