“…They found that hallux valgus feet had a significantly increased medial plantar peak and mean pressure under the first, second and third metatarsal heads. In contrast, hallux limitus feet demonstrated high mean pressure under the hallux and fourth metatarsal heads indicating more load on the lateral forefoot area 23) . These previous studies suggest the change of distribution of FP in the ML and AP directions with aging, deformities, and other diseases directly linked to the change of gait stability and balance.…”

“…A previous study reported that elderly people bore more weight on the lateral side of the foot than young people during heel contact and push-off and that the higher lateral weight bearing may affect stability during gait 12) . Bryant and colleagues 23) studied the difference of FP in normal, hallux valgus, and hallux limitus feet.

Abstract.[Purpose] The measurement of foot pressure (FP) is widely used for the evaluation of gait. The fluctuating changes of FP parameters according to various types of crutch gait, however, are not fully understood. This study examined the changes of FP during normal, two-point, and four-point crutch gait of healthy volunteers.[Subjects] The subjects were thirty-three adults who were 26.5 ± 1.4 years old, weighed 64.2 ± 10.3 kg, and were 168.8 ± 8.7 cm in height.[Methods] FP parameters were collected by a force plate with 2,304 resistive sensors. Regional plantar FP, trajectories of center of pressure (COP) in the anterior-posterior (AP) and the medio-lateral (ML) directions, contact time of foot on the ground, and the relative durations of sub-stages of the stance phase were measured during gait with or without a crutch.[Results] The regional plantar FP significantly decreased during two-point and four-point crutch gait compared with that during normal gait in the AP direction and overall. Analyzed by its trajectory, displacement of COP in the AP direction was significantly smaller during four-point gait than during normal gait. Contact time during two-point and four-point gait was significantly longer than during normal gait. Also, the relative duration of heel contact stage during four-point gait was significantly smaller than during normal gait. The relative durations of the midstance stage during two-point and fourpoint gait, however, were longer than that of normal gait. [Conclusion] These results suggest that types of gait with or without a crutch affect the fluctuation of FP and that may lead to a change of body position and gait pattern. The present data therefore may be useful for understanding the variations of crutch gait.

The objective of this study was to evaluate great toe function in maintaining static and dynamic balance. Correlation among great toe length, body height, and balance performance parameters were also investigated. Thirty females (aged 22.1 AE 1.9 years) were tested in two great toe conditions: unconstrained and constrained. Balance testing was done in the following order: (1) static balance, single-leg stance with right or left foot, eyes open or closed; (2) static balance, stance with both feet, eyes open or closed; (3) dynamic balance, left/right or forward/backward, rhythmic weight shifting; and (4) dynamic balance, target reaching test, eight targets within 90% limit of stability. Significant differences were found in sway velocity between the two toe conditions with eyes open or closed in single-leg stance ( p < 0.05). No difference was found between the two conditions while standing with both feet. For rhythmic weight shifting, significant differences in sway velocity were found in toe conditions and in weight-shifting directions ( p < 0.05). As to target reaching, significance was only noted in directional control scores. Great toe length was correlated with subject's height (r ¼ 0.553, p < 0.05). Our results indicate that constraining the great toe deteriorated the subjects' single-leg stance performance and worsened the directional control ability during forward/backward weight shifting. The importance of the great toe in balance may be taken into account in toe amputation or transfer in the future. ß

“…12,14,20 Dynamic plantar pressure has been used to assess the pressure distribution under the feet of subjects with pathological conditions and under the normal foot during gait. 4,14,20 While a direct link between plantar pressure and joint motion has not been fully developed, the main focus of present research has been to demonstrate trends or changes in pressure with taping to form hypotheses regarding the biomechanics of the foot and lower limb. 30 Research evaluating the effect of LD taping with dynamic measurement tools is limited to 5 published studies.…”

Study Design: A preintervention and postintervention, repeated-measures experimental design. Objectives: To investigate the immediate effect of low-Dye taping on peak and mean plantar pressures during gait in subjects with navicular drop exceeding 10 mm. Background: Low-Dye taping is commonly used to support the longitudinal and transverse arches of the foot in an attempt to reduce the effects of symptoms associated with excessive pronation. Plantar pressure measurement has been used as an indirect indicator of pronation during gait. Method and Measures:The right foot of 60 subjects was tested using the Emed-AT system to obtain plantar pressure values. Subjects performed 6 barefoot walks over the Emed pressure platform while taped and a further 6 walks while untaped. Plantar pressures were recorded. Each footprint obtained was divided into 10 sections or 'masks.' Average peak and mean plantar pressure values (N/cm 2 ) were calculated for both taped and untaped walks for each mask. Results: Paired t tests demonstrated significant changes in peak plantar pressure in 8 of the 10 areas of the foot and significant changes in mean plantar pressure in 9 of the 10 areas of the foot. Low-Dye taping significantly decreased pressure under the heel and the medial and middle forefoot, while increasing pressure under the lateral midfoot and under the toes. A significant decrease in mean plantar pressure was observed under the lateral forefoot, while no significant difference was demonstrated in peak plantar pressure under this area. The area under the medial midfoot demonstrated no significant change in either peak or mean pressure. Conclusions: Low-Dye taping significantly altered peak and mean plantar pressure values in subjects with navicular drop exceeding 10 mm. In particular, peak and mean plantar pressure increased under the lateral midfoot and under the toes, and decreased under the heel and forefoot, suggesting that a decrease in the amount of pronation occurred.
