“…Therefore, the differential across limbs was not due to visual influences. These findings may be relevant for trip training paradigms [15,16], where an increase in obstacle height following a trip may be required if multiple trips in successive trials are desired.…”

During locomotion over uneven terrain, gait must be adapted to avoid a trip. In the event of a foot-obstacle contact, the body reactively responds to the perturbation. However, it is unknown if any proactive adjustments are made in subsequent strides to reduce the likelihood of another contact, and how long any proactive adaptations persist. This study examined gait behavior while stepping over a 10cm obstacle placed in the middle of an 8m walkway. The four obstacle crossings that preceded a spontaneous obstacle contact were compared to the eight obstacle crossings subsequent to the contact. Foot position before the obstacle was not modified following the obstacle contact. However, toe clearance and peak toe elevation increased in the limb that was tripped; the unperturbed limb showed no differences. These findings demonstrate that the sensory information of the perturbed limb proactively influenced the ipsilateral but not the contralateral limb, supporting the idea that the lead and trail limb are controlled independently during obstacle crossing. The proactive adaptation lasted for at least eight trials, suggesting that an unexpected perturbation influences the control of adafptive gait well after obstacle contact.

“…It also has been suggested that improvements in trip recovery performance are possible by training motor skills in short-term, task-specific training studies (i.e. stepping over an obstacle on a suddenly accelerating treadmill) (Bieryla et al, 2007;Troy and Grabiner, 2005). However, these studies did not show a change in success rate in tripping recovery.…”

“…Previous research has demonstrated that older adults can learn within one training session to avoid falling after a forward-directed trip [1,2] and slip [3]. This suggests that fall-prevention programs could benefit from emphasizing task-specific training.…”
