“…Indeed, RFD of the lower limb muscles is associated with walking speed and stand-up movements, supporting the validity of the study results [41,42]. Our previous study of older adults found that toe pressure strength was associated with the presence or absence of assistance standing up from a chair [43]. It has been shown that the toes, even though they are small muscles located in the periphery of the body, are involved in standing up movements, so it is valid and very interesting that toe elements were also involved in the TUG with standing up movements in this study.…”

It has recently been recommended that Rate of Force Development (RFD) be evaluated in addition to maximal muscle strength. There are no studies on RFD of toe pressure strength, and its importance in older adults and the extent to which it is associated with aging needs to be clari ed. This study purpose was to examine the association between the RFD of toe pressure strength and Timed Up and Go Test (TUG) in an age-speci c study. MethodsThis study is a cross-sectional study. Participants in the study included 159 healthy adults (26.3 ± 13.1 years, 52% male) and 88 older adults (75.0 ± 6.2 years, 26% male). The RFD of toe pressure strength was determined from the force-time curve obtained during the toe pressure strength assessment, and the ability to exert maximum muscle force in the shortest possible time was assessed. Regression analysis was performed for each group to test the association between RFD of toe pressure strength and TUG by age. ResultsHealthy adults showed no association between TUG and RFD of toe pressure strength, and signi cant association between TUG and RFD of toe pressure strength was found only in the older adults (standard regression coe cient = − 0.15, p = 0.048). ConclusionThis study showed a signi cant association between TUG and RFD of toe pressure strength in older adults. These ndings show that RFD is one of the functions that should be assessed, particularly in older adults. Furthermore, it was suggested that approaching RFD could improve gait, standing, and sitting movements.

“…In standing, walking and other sports behaviors, muscles drive the phalanges to bend to grasp the ground, which can enhance standing and movement stability ( Zhao, 2022 ). It is worth noting that in the upright stance position, toe muscle strength is closely related to walking and balancing posture ( Kamasaki et al, 2023 ). In addition, toe pressure strength in the standing position discriminated the risk of falling in older adults ( Kamasaki et al, 2020 ).…”

“…In addition, toe pressure strength in the standing position discriminated the risk of falling in older adults ( Kamasaki et al, 2020 ). In fact, toe pressure strength in the standing position may be one of the important muscular forces among those associated with standing up ( Kamasaki et al, 2023 ).…”

Objective: The plantar pressure analysis technique was used to explore the static balance ability and stability of healthy adult males under the influence of visual and step height factors during bipedal and unipedal stances.Methods: Thirty healthy adult males volunteered for the study. Experiments used the F-scan plantar pressure analysis insoles to carry out with eyes open (EO) and eyes closed (EC) at four different step heights. The plantar pressure data were recorded for 10 s and pre-processed to derive kinematic and dynamic parameters.Results: For unipedal stance, most of kinematic parameters of the subjects’ right and left feet were significantly greater when the eyes were closed compared to the EO condition and increased with step height. The differences in toe load between right and left feet, open and closed eyes were extremely statistically significant (p < 0.001). The differences in midfoot load between the EO and EC conditions were statistically significant (p = 0.024) and extremely statistically significant between the right and left feet (p < 0.001). The difference in rearfoot load between EO and EC conditions was extremely statistically significant (p < 0.001) and statistically significant (p = 0.002) between the right and left feet. For bipedal stance, most of kinematic parameters of the subjects’ EO and EC conditions were statistically significant between the right and left feet and increased with step height. The overall load’s difference between EO and EC states was statistically significant (p = 0.003) for both feet. The overall load’s difference between the right and left feet was extremely statistically significant (p < 0.001) in the EC state. The differences between the right and left feet of the forefoot and rearfoot load with EO and EC suggested that the right foot had a smaller forefoot load, but a larger rearfoot load than the left foot (p < 0.001). The differences between the forefoot and rearfoot load of the subjects’ both feet with EO and EC were extremely statistically significant (p < 0.001).Conclusion: Both visual input and step height factors, even the dominant foot, act on kinematic and dynamic parameters that affect the maintenance of static balance ability.
