Immediate effects of different ankle pushoff instructions during walking exercise on hip kinematics and kinetics in individuals with XXXX .

Residual @entity73 , such as decreased hip muscle moment and power during walking, have been reported in @entity1 with @entity572 ( @entity572 ). Meanwhile, greater ankle power has also been reported in these @entity1 . We investigated the interaction between hip and @entity3681 during walking to determine the effects of different ankle pushoff instructions on hip biomechanics in @entity1 with @entity572 . Twenty-four @entity1 (age, 60.8  5.5 years) were randomly assigned to walking exercise groups with either decreased pushoff or increased pushoff. @entity1 in the decreased pushoff group and increased pushoff group were given the instructions "push less with your foot when you walk" and "push more with your foot when you walk," respectively. Exercises lasted approximately 10-15 min. A series of gait-related parameters were analyzed during pre-exercise, exercise, and post-exercise session. In the decreased ankle pushoff group, hip flexor power absorption and hip/ankle power ratio were higher during post-exercise than during pre-exercise. An increase in hip power from -9.8% to 32.1% was identified. The effect of increase in the hip power by the decreasing ankle pushoff was higher in the @entity1 with greater ankle pushoff in their natural gaits. The @entity1 in the increased ankle pushoff group showed decreased hip flexion angle and hip muscle moment and power after the walking exercise, although ankle pushoff was not increased. Walking exercise with decreased ankle pushoff may help improve the distribution of muscle power between hip flexors and ankle plantarflexors during walking in @entity1 with @entity572 .
