This study compared the affected-side laterality in plantar external loading and internal foot tissue stresses in individuals with unilateral shoulder dislocation during 5 km\/h and 7 km\/h treadmill walking conditions, and further examined whether faster walking was associated with changes in this laterality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Twelve participants completed walking trials at two speeds. Peak forces in the rearfoot and forefoot regions were extracted, and the effects of walking speed, affected-side status, and dominant-foot status were analyzed using foot-level linear mixed-effects models. A simplified peak-force-based finite element analysis was used to estimate relative stress responses in key foot soft tissues during loading-response- and push-off-related loading conditions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      The results showed that increased walking speed significantly elevated forefoot peak force (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.005) and was associated with higher stresses in forefoot soft tissues (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.025) and the plantar fascia (\n                      <jats:italic>p<\/jats:italic>\n                      \u202f=\u202f0.003). In contrast, both plantar external loads and internal tissue stresses remained highly symmetrical between the ipsilateral and contralateral feet relative to the affected shoulder, and increasing speed did not amplify affected-side laterality.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>These findings indicate that, within this cohort, faster walking was associated with higher push-off-related plantar tissue stresses, whereas affected-side laterality relative to the dislocated shoulder was not evident. Because no healthy control group or longitudinal pre-injury comparison was included, the results should be interpreted as within-cohort mechanical responses rather than evidence that shoulder dislocation itself increases plantar tissue stress.<\/jats:p>\n
