Abstract
Abstract The aging process causes changes in the physical and functional conditions, as well as in the foot structure and function. This study aimed to analyze the plantar pressure variation with respect to visual information and physical activity in adult and older women. This was a cross-sectional study that included 142 women (mean age of 67.8 years). Participants responded the anamnesis questionnaire, Mini Mental State Examination, and International Physical Activity Questionnaire. Plantar pressure was assessed using computerized baropodometry. Weight distribution was observed in semitandem positions for the right foot forward and then the left foot forward . Data analysis showed that foot type had no correlation with age (p = 0.37 right foot; p = 0.93 left foot) or level of physical activity (p = 0.28 right foot; p = 0.96 left foot). Moreover, plantar pressure variation showed no significant relationship with age (R2 = 0.2; p = 0.6). In conclusion, plantar pressure variation is not associated with the morphological foot type in women analyzed, as the visual condition did not generate plantar pressure variations when compared to its effect on the classification of plantar arches. Furthermore, level of physical activity was not associated with plantar pressure variation .
Highlights
The aging process causes biomechanical, structural, and functional foot changes and is associated with impaired mobility and falls[1]
150 women were deemed eligible to participate in the study, of which eight were excluded for presenting inadequate data to classify their foot type
BMI, body mass index; IPAQ, International Physical Activity Questionnaire; Mini-Mental State Examination (MMSE), MiniMental State Examination; Data are presented as mean (±standard deviation)
Summary
The aging process causes biomechanical, structural, and functional foot changes and is associated with impaired mobility and falls[1]. There is lack of studies in Brazilian and international literature verifying changes in static postural balance related to the quality of therapeutic exercise performed by women in the transition between adult and older ages[5]. The maintenance of this balance is important for performing dynamic daily life activities and practicing physical activities[6]. The discharge of the body weight into the support base is affected by several factors These factors are classified as intrinsic factors, such as physiological disturbances, anthropometric characteristics, and physical condition, and extrinsic factors, such as gravity, erratic ground, and environment[7]
