Wrist Joint Restriction: Impact on Foot Pressure, Center of Gravity, and the Role of the Dominant Hand

<b>Background</b>: Wrist immobilization is a common clinical intervention for wrist injuries; however, its repercussions on gait parameters and plantar support have not been extensively investigated. <b>Objectives</b>: The purpose of the study was to determine whether wrist immobilization causes alterations in foot pressure and center of gravity, considering hand dominance and visual conditions (eyes open or closed). <b>Methods</b>: The research experiment was conducted using the PodoPrint S4 platform. Basic descriptive statistics were calculated to summarize the variables. Additionally, in the mixed linear model (<i>t</i>-tests use Satterthwaite's method) an analysis of variance for repeated measures (ANOVA-RM) was conducted for the determination of the objectives of the study. <b>Results</b>: This study included a total of 44 participants (29 females and 15 males), with an average age of 36.5 years (SD = 17.5). Immobilization, independent of eye condition, resulted in significant alterations in antero-posterior oscillation and in a larger plantar support area. In addition, the results suggest that the eye state significantly influences plantar support, independent of limb immobilization or dominance. <b>Conclusions</b>: Our findings reveal significant alterations in antero-posterior oscillation and plantar support due to immobilization, suggesting a dynamic interplay between wrist function and lower limb biomechanics.
