For example, when experiencing a force perturbation resisting leg flexion during the swing phase of gait
, subjects initially made larger errors in leg kinematics (e.
Pairs of spring were added to the orthosis to produce different levels of muscular activity in Q during the midstance, transition period and terminal swing phase of gait
For example, ability to raise the toe off the floor during the swing phase of gait
is dependent upon ankle dorsal flexion and knee and hip flexion.
By acting as a substitute for dorsiflexor muscles, the brace holds the foot and ankle in position through the important swing phase of gait
For example, dorsiflexor control of the foot is essential to clear the ground during the swing phase of gait
and for ecological landing.
Stance-control orthoses (SCOs) are lower-limb assistive devices that prevent knee collapse during weight-bearing while allowing free knee motion during the swing phase of gait
Initial swing, midswing, and terminal swing formed the swing phase of gait
The control of the hydraulic circuit avoids bilateral hip flexion while providing trunk and hip stability and free or coupled hip movement during the swing phase of gait
Many of these mechanisms are difficult to unlock under load [3 ,8,14], which may be necessary during the transition from the stance phase to the swing phase of gait
Unlocking the orthotic knee joints during the swing phase of gait
improves foot-to-floor clearance and reduces energy cost, while locking them during stance postpones muscle fatigue from stimulation.
During the swing phase of gait
, one has to achieve sufficient clearance of the foot to prevent stumbling.
FES-IM gait training provided subjects with a practice pattern that approximated normal movement of the hip, knee, and ankle during the swing phase of gait
