“…The participants kept looking forward and were not allowed to look down, with the knee joint in flexion. As the dominant leg moved toward the floor while descending, the non-dominant leg maintained balance 14 ) . Movement velocity was controlled by setting a metronome to 30 beats per minute.…”

[Purpose] This study examined the effects of a medio-lateral unstable sole on invertor and evertor activation while descending stairs. [Subjects and Methods] The subjects were 30 university students with no history of ankle sprain. They descended stairs while wearing the medio-lateral unstable sole or with bare feet. Electromyography was used to record the activity of the tibialis anterior and peroneus longus and brevis muscles and paired t-tests were used to assess statistical significance. [Results] The medio-lateral unstable sole group showed increased tibialis anterior and peroneus longus and brevis muscle activation compared to the barefoot group. [Conclusion] Medio-lateral unstable sole can be used with exercises to prevent further ankle damage by activating both the inversion and eversion muscles.

The tibiofemoral joint is known to bear compressive loads of several body-weights during daily activities. These forces are known to be transferred through the joint via compression of the tibial and femoral surfaces against one another. The menisci are also known to enhance this process by increasing the contact area and decreasing contact stress. However, calculations presented in this paper suggest that the load-bearing capacity of contact mechanisms is seemingly several times smaller than tibiofemoral joint loads. This suggests that probably one or more non-contact load-bearing mechanism(s) exist, and share the load with the already known contact mechanisms.

“…Studies of walking on stairs can be divided into 2 major types: (1) those that analyzed features of walking on stairs by comparing patterns of muscles [8][9], ground reaction force [10][11], and the angle of major joints [12][13][14] during stair walking; and (2) those that analyzed the mechanics of walking on stairs by comparing the movements of major joints [15][16][17] and the mechanical power [18][19] exerted during stair walking. Such studies have been conducted in various directions.…”

Normal walking on staircases is a very important ordinary activity. It is a complicated motion that requires a big muscular strength and moment, and a big joint exercise scope. Due to such characteristics, staircase walking may be an obstacle to those with weakened lower limb muscle strength, and actually, fall injury accidents occur. Existing studies focus on dynamic changes in staircase walking. However, this study aimed to analyze staircase-walking characteristics evidenced when applying vibratory somatosensory stimulus to the ankle joint in a bid to reduce the risk of fall injuries associated with staircase walking. Five elderly male subjects, who had no disease related to the musculoskeletal system, participated in experiments. Experiments were held in a motion analysis laboratory equipped with 3-D motion analysis systems, force platforms, etc. In order to gather motion data, subjects wore markers and vibratory stimulation devices designed to apply somatosensory stimulus to ankle joints, and climbed down a staircase with the height adjusted appropriately. Using motion data gathered from staircase-walking, the ankle joint, knee joint and hip joint angles were obtained, and thus each joint's contribution to the motion was calculated. In the case of vibratory somatosensory stimuli being applied to the Achilles's tendon, the ankle joint contributed more to the motion of climbing down a staircase than the knee joint and the hip joint did. On the other hand, in the case of vibratory somatosensory stimulus being applied to the anterior tibialis, the ankle joint contribution was lowered, and to make up for it, the knee joint and the hip joint contribution increased. This outcome revealed that the effect of the vibratory somatosensory stimulation applied to the ankle joint can appear in not only the ankle joint, but also in the whole lower limbs due to chain reaction.
