Influence of rearfoot alignment on static and dynamic postural stability

Abstract

Background/Aims: It has been postulated that foot alignment affects postural stability. However, previous studies reported contradicting results regarding the association between foot alignment and postural stability. Methods: A total of 216 healthy participants aged 15 to 24 years were recruited. Their rearfoot alignment was measured in non-weight bearing and weight-bearing positions. Their static balance was assessed using Balance Error Scoring System and dynamic balance by Star Excursion Balance Test. The relationship between the data obtained were analysed using SPSS version 22 software. Findings: A Pearson correlation with a 95% confidence interval reported that there was: (i) no significant difference in the rearfoot alignment between both genders; (ii) no significant relationship between the rearfoot alignment measured in prone lying and unilateral stance position; (iii) a weak negative correlation between the rearfoot alignment measured in prone lying position to dynamic balance on medial, posterior, lateral, anterolateral and posteromedial direction; (iv) no significant relationship between the rearfoot alignment measured in unilateral stance position to both static and dynamic postural balance. Conclusions: Rearfoot alignment measured in non-weight bearing position plays some role in postural stability and therefore should be considered in sports rehabilitation. However, this can be overlooked in rehabilitation for individuals whose postural stability is not the primary concern.

Correlation of medial longitudinal arch height with postural stability, sensory integration, balance and fall risk among healthy young adults

“…A study conducted by Fu GQ et al has shown no significant relationship of rear foot alignment with static and dynamic postural balance. 24 Another study Mun K-R et al has shown medial longitudinal arch height to be correlated with postural stability in anteroposterior direction, 25 however the relationship was non-significant (p>0.05), similar to the findings of the current study. Moreover, the sample size of Mun K-R's study was small, consisting of only 13 healthy young adults with a mean age of 28.08 years.…”

Prevalence, Associated Factors and Psychological Determinants of Obesity among Adults in Selangor, Malaysia

“…Mortality from these chronic diseases is highly associated with obesity [10]. Besides, obesity also increases loading at the weight-bearing joint, leading to functional locomotor disability, the main cause of physical inactivity that contributes eventually to increased morbidity and mortality [11][12][13]. In other words, obesity indirectly shortens life expectancy while directly impacting the individual's quality of life and psychological well-being as it could lead to depression or low self-esteem [14][15][16][17].…”
