What causes a crossover step when walking on uneven ground? A study in healthy young women. (2007)
Journal Article
Thies, S., Ashton-Miller, J., & Richardson, J. (2007). What causes a crossover step when walking on uneven ground? A study in healthy young women. Gait & Posture, 26(1), 156-160. https://doi.org/10.1016/j.gaitpost.2006.08.011

We hypothesized that, during gait, the perturbation caused by stepping on a 1.2-cm high protuberance with the medial forefoot would not only alter stance foot kinematics and kinetics, but also alter subsequent step location and timing, even to the po...

Influence of an irregular surface and low light on the step variability of patients with peripheral neuropathy during level gait (2005)
Journal Article
Thies, S., Richardson, J., DeMott, T., & Ashton-Miller, J. (2005). Influence of an irregular surface and low light on the step variability of patients with peripheral neuropathy during level gait. Gait & Posture, 22(1), 40-45. https://doi.org/10.1016/j.gaitpost.2004.06.006

Patients with peripheral neuropathy (PN) report greater difficulty walking on irregular surfaces with low light (IL) than on flat surfaces with regular lighting (FR). We tested the primary hypothesis that older PN patients would demonstrate greater s...

Interventions improve gait regularity in patients with peripheral neuropathy while walking on an irregular surface under low light. (2004)
Journal Article
Richardson, J., Thies, S., DeMott, T., & Ashton-Miller, J. (2004). Interventions improve gait regularity in patients with peripheral neuropathy while walking on an irregular surface under low light. Journal of the American Geriatrics Society, 52(4), 510-515. https://doi.org/10.1111/j.1532-5415.2004.52155.x

Objectives: To determine which, if any, of three inexpensive interventions improve gait regularity in patients with peripheral neuropathy (PN) while walking on an irregular surface under low-light conditions. Design: Observational. Setting:... Read More about Interventions improve gait regularity in patients with peripheral neuropathy while walking on an irregular surface under low light..
