One of the most common causes of falls in older adults is tripping while walking (Campbell, Reinken, Allan, & Martinez, ; Tinetti et al., ).Older adults are more likely to fall after a trip than younger adults (Pijnappels, Bobbert, & van Dieën, ; Schillings, Mulder, & Duysens, ).An understanding of the underlying causes why older adults are more 7.

Although several studies show the effectiveness of Tai Chi (TC) on balance control, (), no studies have, to date, examined effects of TC on biomechanical responses to large, fast walking perturbations in impaired that balance recovery during walking involves the ability to make rapid, coordinated, and accurate adjustments of body posture to prevent falling   •Previous studies have focused on the biomechanical effects of knee bracing after ACLR •However, knee bracing and taping may also improve functional performance during tasks such as single limb balance and self-reported knee function in ACLR individuals •Although the use of knee bracing and taping after ACLR is still an area of discussion The optimal stepping strategies depend on the phase that a trip occurs that is, an elevating strategy during early swing and a lowering strategy during late swing.

The intervention group (%) had a similar frequency of the lowering strategy compared with Strategies for recovery from a trip in early and late swing during human walking.

Introduction. Falls are a major health problem for older adults. They have been associated with reduced ability to perform daily activities, leading to an avoidance of walking, shopping, or housekeeping, and increased risk of nursing home admission (Tinetti, ).In the United States, falls are the leading cause of accident-related deaths in persons 79 years and older (Hoskin, ).

Slip trials were classified as falls if the peak force recorded by the load cell inline with the overhead harness exceeded 30% of the participant’s body weight (Yang and Pai ).All falls were confirmed by a decrease in hip height (Beschorner and Cham ; Pai et al. ), attenuation of forward center-of-mass velocity (Fig.
