Recruitment of the plantar intrinsic foot muscles with increasing postural demand

Influencia do indice de massa corporal no equilibrio e na configuracao plantar em obesos adultos

“…Sugere-se que parte da nossa amostra possa ter sido composta por voluntários que tenham apresentado algum desconforto localizado na planta dos pés causado pela tração constate sobre fáscia plantar durante a descarga de peso na fase de apoio da marcha ou durante a manutenção prolongada do ortostatismo 17 . Assim, a maior frequência do pé cavo pode ser resultado de uma postura antálgica para aliviar o desconforto, sobre a fáscia plantar, por meio da pisada predominantemente na face lateral do pé para a manutenção do arco elevado.…”

Effects of Foot Arch Structure on Postural Stability

“…Wright et al [4] reported that foot arch deformations and body sway were significantly correlated during quiet standing, indicating that the arch was related to postural sway. Kelly et al [5] have reported that there is a correlation in the change of CoP and the activity of the plantar intrinsic foot muscles. The foot arch is also believed to have a role in postural sway since the plantar intrinsic foot muscles form the foot arch.…”

“…Wright et al [4] used a linear transducer and force plate to examine the relationship between the deformation of the foot arch and CoP sway in seven subjects. Kelly et al [5] measured body sway and muscle activity of the plantar intrinsic muscles in ten young people, using a wire electrode electromyogram and force plate. By contrast, the present study used the Shoe Type Stabilometer to evaluate postural control focusing on the individual foot arch structure and conducted measurements in over 100 subjects.…”

“…One reason for this lack of findings may be that subjects in these studies were restricted to patients with disease or several young participants able to use large equipment (e.g. force plate, threedimensional (3D) motion analyzer) [5,6].…”

Static, dynamic balance and functional performance in subjects with and without plantar fasciitis

“…These compensations change joint position sense and muscle activations, causing body oscillations that make it dif icult to maintain an upright posture within the base of support. This can impair the static and dynamic balances (2,16).…”
