Light-Weight Wearable Gyroscopic Actuators Can Modulate Balance Performance and Gait Characteristics: A...

Area of Science:

• Robotics
• Biomechanics
• Human Augmentation

Background:

• Falling is a significant cause of morbidity, often linked to reduced postural stability.
• Whole-body centroidal angular momentum is crucial for postural stability and can be modulated by control moment gyroscopes.

Purpose of the Study:

• To investigate the effect of a wearable robotic gyroscopic actuator, the GyroPack, on balance and gait in healthy individuals.
• To assess how different control modes of the GyroPack influence postural control and walking characteristics.

Main Methods:

• Proof-of-concept study involving 15 non-impaired participants (7 female/8 male).
• Participants performed balance and walking tasks with and without the GyroPack in various control modes.
• Measurements included mediolateral standing time, walking distance on a balance beam, and trunk angular velocity variability during treadmill walking.

Main Results:

• As a damper, GyroPack improved mediolateral standing time and balance beam walking distance.
• The damper configuration also decreased trunk angular velocity variability during treadmill walking.
• As a negative damper, GyroPack increased peak trunk angular rate and trunk angular velocity variability during treadmill walking.

Conclusions:

• Gyroscopic actuators can significantly influence human balance and gait kinematics.
• The GyroPack demonstrated potential for enhancing postural control, with a lighter design making clinical applications more feasible.
