The Role of Tibialis Posterior on Foot Kinematics during Walking
نویسندگان
چکیده
Many overuse injuries of the lower extremity are associated with excessive/prolonged pronation of the foot during gait. Pronation is a complex motion and its quantification during gait has mainly been limited to rearfoot motion. However, foot pronation also occurs across the more distal joints of the foot. Thus it is pertinent to quantify both rearfoot and forefoot motion when assessing pronation. In vitro studies suggest that the tibialis posterior muscle may play a role in preventing collapse of the medial longitudinal arch, contribute to rearfoot inversion, and adduct the forefoot [1]. In addition, patients with posterior tibial tendon dysfunction (PTTD) demonstrate increased rearfoot eversion along with increased dorsiflexion and abduction of the forefoot [2]. These studies suggest that the tibialis posterior function is important in controlling both the rearfoot and forefoot mechanics associated with pronation.

The role of tibialis posterior fatigue on foot kinematics during walking
BACKGROUND The purpose of this study was to investigate the effect of localised tibialis posterior muscle fatigue on foot kinematics during walking. It was hypothesised that following fatigue, subjects would demonstrate greater forefoot and rearfoot motion during walking. It was also postulated that the magnitude of the change in rearfoot motion would be associated with standing anatomical rear...

Changes in joint coupling and variability during walking following tibialis posterior muscle fatigue
BACKGROUND The tibialis posterior muscle is believed to play a key role in controlling foot mechanics during the stance phase of gait. However, an experiment involving localised tibialis posterior muscle fatigue, and analysis of discrete rearfoot and forefoot kinematic variables, indicated that reduced force output of the tibialis posterior muscle did not alter rearfoot and forefoot motion duri...

Tibialis posterior has a vital role during gait as the primary dynamic stabiliser of the medial longitudinal arch; however, the muscle and tendon are prone to dysfunction with several conditions. We present an overview of tibialis posterior muscle and tendon anatomy with images from cadaveric work on fresh frozen limbs and a review of current evidence that define normal and abnormal tibialis po...
متن کاملEffect of Textured Foot Orthoses on the Ground Reaction Force Components in the Older Adults During Walking
Introduction: With aging, the pattern of walking is altered, and the person’s ability to walk will be decreased. Also, with the beginning of the aging process, the coordination of the postural control system was disturbed and lead to an unstable condition. A small biomechanical change in the lower limb is significant on postural control. The use of textured foot orthoses leads to improved effic...
