Outcome Measures

Primary Outcomes (1)

Postural stability
Postural stability at the recovery steps after the perturbation will be calculated as the distance between the absolute center of mass (CoM) position in an anteroposterior direction relative to the closest edge of the Base of Support (BoS) normalized by foot length. The absolute CoM position and BoS position will be traced by the motion capture system synchronized with the force plates embedded underneath the slip-treadmill belts.
Pre-intervention, 1 week after intervention and 4 months after intervention.

Secondary Outcomes (13)

Generic balance ability
Pre-intervention, 1 week after intervention and 4 months after intervention.
Mobility
Pre-intervention, 1 week after intervention and 4 months after intervention
Number of real-life falls
1 month, 2 months, 3 months, 4 months, 5 months, 6 months, 7 months, 8 months, 9 months, 10 months, 11 months, and 12 months after the intervention.
Dynamic balance
Pre-intervention, 1 week after intervention and 4 months after intervention.
Balance confidence
Pre-intervention, 1 week after intervention and 4 months after intervention.

Study Arms (2)

Reactive balance training with augmented reality group

EXPERIMENTAL

The group will receive two sessions of treadmill-based reactive balance training with 240 forward and backward perturbations, simulating tripping and slipping, while walking with augmented reality headsets.

Behavioral: Reactive balance training with augmented reality group

Control group

ACTIVE COMPARATOR

The group will receive two sessions of treadmill walking without perturbation and augmented reality.

Behavioral: Treadmill walking

Interventions

Reactive balance training with augmented reality groupBehavioral

It will be two sessions of treadmill-based RBT with 240 forward and backward perturbations, simulating tripping and slipping, while walking with augmented reality headsets. Each session will last approximately one hour. Participants will be instructed to recover their balance and continue walking after each perturbation.

Reactive balance training with augmented reality group

Treadmill walkingBehavioral

It will be a two sessions training with each session lasting for approximately an hour. The same training duration and format will be used as the experimental group, except that no perturbations and augmented reality will be induced during the treadmill walking.
