OBJECTIVES: To investigate the relationship between the first metatarsophalangeal joint angle (Ang-I), the age, anthropometric measures and foot posture of older adults. METHODS: The sample was composed of 227 older women with a mean age of 69.6 (±6.8) years and 172 older men with a mean age of 69.4 (±6.7) years. The studied variables were: the width and circumference of the metatarsal heads, the height of the first metatarsal head and the dorsum of the foot, the length of the foot, the Ang-I and fifth metatarsophalangeal joint angles, the arch index and the foot posture index. The measurements were taken with analog instruments. The data were analyzed using Pearson's correlation. RESULTS: There was no association between Ang-I and age or arch index, but there were positive associations between Ang-I and the width and circumference of the metatarsal heads, the foot posture index and the fifth metatarsophalangeal angle. There was a negative association between Ang-I and the height of the dorsum of the foot. CONCLUSIONS: Relationships were found between greater Ang-I values and greater widths and circumferences of the forefeet, greater fifth metatarsophalangeal angles and greater pronation of the feet and smaller values for the height of the dorsum of the foot.

Aim: To compare the effects of 16-week multicomponent and resistance training, and 6-week detraining on physical variables related to a higher risk of falls in very old people., Methods: A randomized, three-arm, controlled trial was carried out. A total of 69 community-dwelling older adults aged 80 years and older were allocated to three groups: control, multicomponent training and resistance training. They were assessed at baseline, after 16-week training and 6-week detraining. The control group did not perform any intervention. The multicomponent group performed protocol consisting of warm-up, aerobic, strength, balance and cool-down exercises. The resistance group underwent strength exercises using six adapted machines. The training sessions had progressive intensity, lasted 16 weeks and 12 included three 1-h sessions per week. The assessment consisted of anamneses, five-repetition sit-to-stand, one-leg standing, tandem and dual task tests. For statistical analysis, α = 0.05 was used., Results: There were no significant differences between groups and assessments in any variable when analyzed by intention to treat. However, when analyzed, the older adults who adhered to the training, the multicomponent group, had a significant improvement in the sit-to-stand and the one-leg standing (right support) tests. There was a significant main effect between times on the one-leg standing (left support) test., Conclusion: In very old people, multicomponent training seems to be more beneficial and presents fewer adverse events when the adherence to protocol is higher., (© 2015 Japan Geriatrics Society.)

Background: The purpose of the study was to investigate the relationship between dual task walking, cognition, and depression in oldest old people living in the community., Methods: We conducted an observational cross-sectional study at Federal University of São Carlos (Brazil). We assessed 67 community-dwelling older adults aged 80 years and over, who were able to walk alone and did not present with a risk of dementia (assessed by Mini-Mental State Examination, MMSE). The assessment consisted of anamnesis, dual task using the Timed Up and Go test associated with a motor task (TUGT-motor) and a cognitive task (TUGT-cognitive); cognitive measures using MMSE, Montreal Cognitive Assessment (MoCA), Clock Drawing test (CDT) and verbal fluency, and depressive measures by the Geriatric Depression Scale (GDS)., Results: There was a correlation with higher magnitude between cognitive tests and TUGT-cognitive, compared to TUGT-motor. For TUGT-motor, the highest correlations with cognitive tests were found between time and MMSE, MoCA (total score), and MoCA visuospatial/executive domain. For TUGT-cognitive, the highest correlations with cognitive tests were between number of steps and MMSE and between time and MMSE. GDS showed a significant weak correlation with number of steps taken in TUGT-motor, wrong words, and correct/time of TUGT-cognitive., Conclusions: Dual task performances are associated with cognition in oldest old. Furthermore, dual task tests have less influence of educational level, are functional, fast, and easily applicable in clinical practice. Future studies are needed to confirm if dual task test is useful for cognitive screening in oldest old.

Aim: To investigate the relationship between balance and dual task performance in adults aged over 80 years, and to analyze possible differences between fallers and non-fallers in dual task performance., Methods: An observational cross-sectional study was carried out at the Federal University of São Carlos (Brazil). We assessed 67 community-dwelling older adults aged over 80 years who were able to walk. The volunteers were divided into groups of fallers and non-fallers. The one-leg standing and tandem tests were used to assess balance. Dual task was assessed by the Timed Up and Go test, associated with a motor task (TUGT-motor) and a cognitive task (TUGT-cognitive). Statistical analyses were carried out, and the significance level was set at α = 5%., Results: Significant correlations were found between balance and dual task variables. Fallers took significantly more time and steps on both the TUGT-motor and the TUGT-cognitive, with no significant differences on balance tests between groups., Conclusions: Recognizing the influence of dual task walking on balance and fall risk could help health professionals to prevent falls in older adults, as well as optimize assessment and intervention planning., (© 2015 Japan Geriatrics Society.)

Context: Some questions remain regarding the anthropometric differences between the feet of young men and women, but the gap is much greater when dealing with older adults. No studies were found concerning these differences in an exclusively older adult population, which makes it difficult to manufacture shoes based on the specific anthropometric measurements of the older adult population and according to gender differences., Objective: To identify differences between the anthropometric foot variables of older men and women., Design: Cross-sectional., Participants: 154 older women (69.0 ± 6.8 y) and 131 older men (69.0 ± 6.5 y)., Main Outcome Measures: The foot evaluations comprised the variables of width, perimeter, height, length, 1st and 5th metatarsophalangeal angles, the Arch Index (AI), and the Foot Posture Index (FPI). A data analysis was performed using t test and a post hoc power analysis., Results: Women showed significantly higher values for the width and perimeter of the toes, width of the metatarsal heads, and width of the heel and presented significantly lower values for the height of the dorsal foot after normalization of the data to foot length. The 1st and 5th metatarsophalangeal angles were smaller in the men. There were no differences between men and women with respect to AI and FPI., Conclusions: Overall, the current study shows evidence of differences between some of the anthropometric foot variables of older men and women that must be taken into account for the manufacture of shoes for older adults.

We wanted to evaluate the postural characteristics of the feet of older people and their relationship with the BMI. We evaluated 227 older women and 172 older men with respect to the BMI, the arch index (AI) and the foot posture index (FPI). The obese women presented mean values for the AI significantly greater than those of the normal and overweight women. The means for some of the criteria of the FPI were significantly higher in the obese men. There was a positive correlation between the BMI and the AI and some of the FPI criteria. The conclusion was that obese women presented flatter feet while obese men presented more pronated feet, indicating a relationship between high BMI values and postural characteristics of the feet of subjects studied., (Copyright © 2010 Elsevier Ireland Ltd.

Context: Wearing inappropriate shoes can cause biomechanical imbalance, foot problems, and pain and induce falls., Objective: To verify the prevalence of wearing incorrectly sized shoes and the relationship between incorrectly sized shoes and foot dimensions, pain, and diabetes among older adults., Design: A cross-sectional study., Participants: 399 older adults (227 women and 172 men) age 60 to 90 y., Main Outcome Measures: The participants were asked about the presence of diabetes, pain in the lower limbs and back, and pain when wearing shoes. Foot evaluations comprised the variables of width, perimeter, height, length, first metatarsophalangeal angle, the Arch Index, and the Foot Posture Index. The data analysis was performed using a 2-sample t test and chi-square test., Results: The percentage of the participants wearing shoe sizes bigger than their foot length was 48.5% for the women and 69.2% for the men. Only 1 man was wearing a shoe size smaller than his foot length. The older adults wearing the incorrect shoe size presented larger values for foot width, perimeter, and height than those wearing the correct size, but there were no significant differences between the groups with respect to the Arch Index and the Foot Posture Index. Incorrectly sized shoes were associated with ankle pain in women but not with diabetes. Men were more likely to wear incorrectly fitting shoes. The use of correctly sized shoes was associated with back pain in women., Conclusions: The use of incorrectly sized shoes was highly prevalent in the population studied and was associated with larger values for foot width, perimeter, and height and with ankle pain.

Age-related and arthritis-related foot modifications have been described in literature, but there is a lack of references that allow shoes to be designed on the basis of specific anthropometric measurements of older women. The aim of this study was to identify the anthropometric characteristics of the feet of elderly women with and without arthritis. This is an observational transversal study. The right and left feet of 227 older women aged between 60 and 90 years (69.6 + or - 6.8 years) were evaluated, of whom 45 reported a diagnosis of arthritis (non-osteoarthritis). The anthropometric evaluation of the feet comprised the variables of width, perimeter, height, foot length, first and fifth metatarsophalangeal angles, the arch-index and the foot posture index (FPI). The data were analyzed using the analysis of probability to compare the groups (arthritic and non-arthritic women). The differences between the means were significant in the case of the FPI and some of its criteria, such as the calcaneal frontal plane position, the bulge in the region of the talo-navicular joint and the forefoot alignment. The width of the right foot was also significantly greater in the women with arthritis. These results are preliminary findings that may help direct larger studies of foot characteristics among older adults with arthritis., (Copyright 2009 Elsevier Ireland Ltd. All rights reserved.)

Objective: To verify the prevalence of pain among older people when wearing shoes, and the relationships between foot pain, high-heeled shoes and anthropometric variables., Method: Both feet of 227 older women and 172 older men were evaluated with respect to anthropometric variables, arch index and foot posture index. The participants were also asked about the presence of foot pain while wearing high-heeled shoes. The data were analyzed using the Chi-square test, Pearson's correlation, MANOVA, multiple regression analysis, t test, and analysis of probability., Findings: The prevalence of foot pain when wearing shoes was high and was associated with the female gender, however wearing high-heeled shoes was not associated with pain. The women with foot pain presented larger values for the circumferences of the metatarsal heads and the instep (after normalization with the foot length) than those without pain. The men with pain did not present different measurements from those without pain.
