introduction the abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. the abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. this nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. it has been reported that 1% to 2.7% o...

Joplin's neuroma is a rare perineurial fibrosis of the medial plantar digital proper nerve arising from various etiologies but most commonly after bunion surgery. Treatment for this painful great toe problem remains controversial. It is our purpose to describe our experience with this chronic pain problem, considering it to be a neuroma requiring resection. A retrospective medical record review...

This study compared the ground reaction forces (GRF) and plantar pressures between unloaded and occasional loaded gait. The GRF and plantar pressures of 60 participants were recorded during unloaded gait and occasional loaded gait (wearing a backpack that raised their body mass index to 30); this load criterion was adopted because is considered potentially harmful in permanent loaded gait (obes...

[Purpose] The purpose of the present study was to investigate differences in plantar pressure between individuals with normal and pronated feet according to 3 static squat depths. [Subjects and Methods] Study subjects were 10 young adults with normal and pronated feet. Plantar pressures were measured in the standing position and static squat positions at 45° (semi-squat) and 90° (half-squat) kn...

The fol lowing report of the occurrence of tuberculoid leprosy in an albino is of interest since , as far as can be ascertained , no such case has been reported previously . A young adult male peasan t (age between 2 6 a n d 3 0 years) from the rural part of M orogoro District , sought admission to the Chazi leprosarium on 20 May , 1 97 1 , because of plantar ulcers on both fee t . He said he h...

BACKGROUND Plantar pressure measurements often are used as a tool to evaluate pathologic gait. Previous studies, often done at self-selected walking speeds, have used peak plantar pressure to try to predict ulcer formation, compare surgical outcomes, and evaluate orthotic device efficacy. However, the relationship between walking speed and plantar pressures at specific plantar regions has not b...

OBJECTIVE To investigate the correlation between the Foot Posture Index (FPI) (including talar head palpation, curvature at the lateral malleoli, inversion/eversion of the calcaneus, talonavicular bulging, congruence of the medical longitudinal arch, and abduction/adduction of the forefoot on the rare foot), plantar pressure distribution, and pediatric flatfoot radiographic findings. METHODS ...

This study focuses on neuromuscular mechanisms behind ankle torque and EMG variability during a maintained isometric plantar flexion contraction. Experimentally obtained torque standard deviation (SD) and soleus, medial gastrocnemius, and lateral gastrocnemius EMG envelope mean and SD increased with mean torque for a wide range of torque levels. Computer simulations were performed on a biophysi...
