“…The kinematic data illustrate modifications to body segment configurations, which indicate that both ground reaction forces and joint moments are also altered due to a change in surface slope [9]. Compared with level walking, during both uphill and downhill walking, the normal component of the ground reaction force is similar in shape with differing peak values while the parallel component demonstrates specific, significant differences dependent upon grade.…”

Despite continual fluctuations in walking surface properties, humans and animals smoothly transition between terrains in their natural surroundings. Walking transitions have the potential to influence dynamic balance in both the anterior -posterior and medial -lateral directions, thereby increasing fall risk and decreasing mobility. The goal of the current manuscript is to provide a review of the literature that pertains to the topic of surface slope transitions between level and hill surfaces, as well as report the recent findings of two experiments that focus on the neuromuscular strategies of surface slope transitions. Our results indicate that in anticipation of a change in surface slope, neuromuscular patterns during level walking prior to a hill are significantly different from the patterns during level walking without the future change in surface. Typically, the changes in muscle activity were due to co-contraction of opposing muscle groups and these changes correspond to modifications in head pitch. In addition, further experiments revealed that the neck proprioceptors may be an initial source of feedback for upcoming surface slope transitions. Together, these results illustrate that in order to safely traverse varying surfaces, transitions strides are functionally distinct from either level walking or hill walking independently.

“…Surface Electromyography (sEMG) provides a safe, easy and non-invasive method to quantify the energy of the muscles [1]: for these reasons sEMG is currently becoming more and more a powerful tool for the assessment in sport [2], [3], rehabilitation [4], [5], ergonomic design [6], [7], and medical robotics [8].…”

Abstract. [Purpose] We examined the characteristics of lower limb muscles of the elderly in climbing stairs as a fall prevention study. [Methods] This study selected 40 elderly people aged 60 or older who could walk independently. The activity of climbing stairs was divided into four stages: standing, knee flexion, touching the stair, and ascending. Muscle activities of the lower limbs were measured by electromyography.[Results] There were significant differences in the activities of four muscles in the four stages of climbing stairs. The right leg showed significant differences in onset times of the four muscles, activities, but the left leg showed no significant differences. [Conclusion] Activity of the tibialis anterior and medial gastrocnemius muscles were different at each stage of climbing stairs. We also found that the tibialis anterior was activated first to prevent dragging of the right leg, and the left leg muscles worked simultaneously to provid stability.
