“…This is followed by movements in the yaw plane, which start from the head, proceed to the trunk, and end at the foot in a top-down manner [3,4]. A similar top-down sequence in segment reorientation also has been reported in healthy elderly as they turn in the middle of their walk [5][6][7][8].…”

“…Individuals with increased neck tone and decreased neck mobility may suffer additional challenges during walking on non-level surfaces. For instance, individuals with Parkinson's disease rotate the head and the trunk simultaneously during walking and turning [40][41][42]. To add, Franzen et al [43] correlated neck tone and walking performance on six functional tests.…”

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.

“…Although there is evidence that even pathologies at subclinical phase may be detectable by a standard gait analysis test (considering only plain gait at self-selected speed) [2,3], such an approach may be unsatisfactory in a number of cases: some earlystage diseases may not primarily affect plain gait, but more challenging or specific tasks like steering or initiating gait [4,5], toe-walking, and heel-walking [6]. For this reason, we think that adding properly other selected locomotor tasks to standard gait analysis could be helpful for many borderline or subclinical cases.…”
