简要总结
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.
详细描述
Participants will be randomly assigned to two groups receiving SePBT or control group. All participants will give their written informed consent before baseline assessment. The study will be reported and conducted in line with the CONSORT statement. Participants will be recruited via convenient sampling in the local community. After baseline assessment, both groups will go through two 30-minute training session over two weeks. Between-group differences in behavior will be examined before and after training to identify training-induced changes in postural stability. Retention of the changes in the postural stability will be assessed four months after the training period. Incidents of falls will be followed up for 12 months after training.

结局指标
主要结局
Postural stability
时间窗: Pre-intervention, 1 week after intervention and 4 months after intervention.
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.
