• 1 other identifier: HSEARS20240505001
• Study Type: interventional
• Target: 48

Brief Summary

This is a single-blinded study. Participants will be randomly assigned to self-initiated perturbation-based balance training (SePBT) group or control (conventional balance training) group. Kinematic and Kinetic changes following SePBT group compared to control will be investigated.

Conditions

Healthy Subjects (HS)

Keywords

Perturbation; Step training; Falls

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 (16)

• 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.

• Responsive postural adjustment upon translation

  Pre-intervention, 1 week after intervention and 4 months after intervention.

• Responsive postural adjustment upon tilting

  Pre-intervention, 1 week after intervention and 4 months after intervention.

Study Arms (2)

Self-initiated perturbation-based balance training group

EXPERIMENTAL

This group will receive two sessions of self-initiated perturbation-based balance training.

Behavioral: Self-initiated perturbation-based balance training

Conventional balance training group

ACTIVE COMPARATOR

This group will receive two sessions of balance and strength training.

Behavioral: Conventional balance training

Interventions

Self-initiated perturbation-based balance training BEHAVIORAL

This group will receive two 30-minute training sessions over two weeks, with one session per week. Participants will be required to recover their balance upon self-initiated perturbation.

Self-initiated perturbation-based balance training group

Conventional balance training BEHAVIORAL

This group will receive two 30-minute training sessions over two weeks, with one session per week. Participants will be instructed to perform balance and strength training. The same training duration and format will be used as the Self-initiated perturbation-based balance training group.

Conventional balance training group
