“…In this study, COP average velocity between FI and FPBI in the Romberg posture with eyes closed and dominant single leg standing position with eyes opened was significantly decreased (p<0.05). Previous studies reported individuals in the supinated feet group of healthy young adults had significantly greater COP average speed [15], and mean values of COP total velocity during standing with and without insole were significantly decreased in subjects with flat feet [34]. Postural sway is affected by the visual, proprioception, and vestibular system.…”

The purpose of this research was to determine the immediate effects of wearing a foot-pressure-based insole (FPBI) on ankle dorsiflexion range of motion (DFROM), postural sway, and muscle activation in healthy individuals with genu varum. Design: Cross-sectional study. Methods: This study was conducted on thirteen adults, with six male and seven females subjects. The mean age was 24.08 years. Foot pressure was measured to apply the FPBI and the weight bearing lunge test was performed with the application of a flat insole (FI) and FPBI. Examination was randomly performed in four conditions to measure both postural sway and muscle activation. All participants applied both the FI and FPBI with four conditions. The four conditions were as follows: 1) Romberg test posture with eyes closed, 2) Romberg test posture with eyes opened, 3) dominant single leg standing with eyes opened, and 4) non-dominant single leg standing with eyes opened. Results: For ankle DFROM between the FI and FPBI, a significant increase was observed in both the dominant and non-dominant leg (p<0.05). For postural sway between the FI and FPBI in the Romberg test posture with eyes closed and dominant single leg standing with eyes opened conditions, a significant decrease was observed (p<0.05). However, the postural sway between FI and FPBI in the Romberg test posture with eyes opened and non-dominant single leg standing with eyes opened, no significant decrease was observed. Also, there were no significant effects on muscle activation between the application of the FI and FPBI. Conclusions: The result showed that FPBI immediately improved ankle DFROM and postural sway. It seems that FPBI may improve genu varum in healthy individuals with genu varum.

This study examined the effects of flexible flatfeet on the accuracy of knee joint motions in closed and open kinetic chain tasks. Methods: Twenty-four healthy participants were recruited for this study. The subjects were divided into two groups using a navicular drop (ND) test: flexible flatfoot group (n= 12, male: 6, aged 22.00± 2.22 years) and age-matched control group (n= 12, males: 6, aged 22.17± 1.53 years). The accuracy of knee motion was measured quantitatively by tracing through the flexion and extension motion of the knee joints in the closed kinetic chain and the open kinetic chain. Results: There was a significant difference in the accuracy index between the groups in closed kinetic chain task, but there was no significant difference in the open kinetic chain task. In addition, there was a significant difference in the accuracy index between the closed kinetic chain and the open kinetic chain task in the flexible flatfoot group. In addition, a significant negative correlation was observed between the ND and accuracy index in the closed kinematic chain task, but there was no significant relationship between the ND and accuracy index in the open kinematic chain task. Conclusion: Flexible flatfeet can affect the accuracy of the adjacent joints, such as the knee joint in the closed kinematic chain.

“…In young adults, Cobb et al [11] reported that those with forefoot varus exhibited greater antero-posterior postural sway in single limb stance, which they attributed to decreased joint congruity associated with the planus foot. Similarly, Tsai et al [12] reported that young adults with planus feet demonstrated greater antero-posterior postural sway in single limb stance and were able to maintain balance for a shorter duration than those with neutral feet, and Tahmasebi et al [13] found that sway velocity in young adults was greater in those with flat feet according to arch index measurements. In older adults, Spink et al [14] found that planus foot posture was associated with poorer performance on a test of postural sway.…”

Background: The foot plays an important role in supporting the body when undertaking weight-bearing activities. Aging is associated with an increased prevalence of foot pain and a lowering of the arch of the foot, both of which may impair mobility. Objective: To examine the associations of foot pain, foot posture and dynamic foot function with self-reported mobility limitations in community-dwelling older adults. Methods: Foot examinations were conducted on 1,860 members of the Framingham Study in 2002-2005. Foot posture was categorized as normal, planus or cavus using static pressure measurements, and foot function was categorized as normal, pronated or supinated using dynamic pressure measurements. Participants were asked whether they had foot pain and any difficulty performing a list of eight weight-bearing tasks. Multivariate logistic regression and linear regression models were used to examine the associations of foot pain, posture, function and ability to perform these activities. Results: After adjusting for age, sex, height and weight, foot pain was significantly associated with difficulty performing all eight weight-bearing activities. Compared to those with normal foot posture and function, participants with planus foot posture were more likely to report difficulty remaining balanced [odds ratio (OR) = 1.40, 95% confidence interval (CI) 1.06-1.85; p = 0.018] and individuals with pronated foot function were more likely to report difficulty walking across a small room (OR = 2.07, 95% CI 1.02-4.22; p = 0.045). Foot pain and planus foot posture were associated with an overall mobility limitation score combining performances on each measure. Conclusion: Foot pain, planus foot posture and pronated foot function are associated with self-reported difficulty undertaking common weight-bearing tasks. Interventions to reduce foot pain and improve foot posture and function may therefore have a role in improving mobility in older adults.
