Rehabilitation following spinal cord injury is likely to depend on recovery of corticospinal systems. Here we investigate whether transmission in the corticospinal tract may explain foot drop (inability to dorsiflex ankle) in persons with spinal cord lesion. The study was performed in 24 persons with incomplete spinal cord lesion (C1 to L1) and 15 healthy controls. Coherence in the 10- to 20-Hz...

OBJECTIVE To compare walking energy cost between an anterior and a posterior ankle-foot orthosis in people with foot drop. DESIGN Within-group comparisons. PARTICIPANTS Twenty-three adults (14 women, 9 men; mean age 56.8 years (standard deviation 15.4)) with foot drop. METHODS PARTICIPANTS were asked to walk for 5 min at their self-selected walking speed under 3 conditions: (i) with shoes...

OBJECTIVE To investigate the feasibility of unsupervised community use of an array-based automated setup functional electrical stimulator for current foot-drop functional electrical stimulation (FES) users. DESIGN Feasibility study. SETTING Gait laboratory and community use. PARTICIPANTS Participants (N=7) with diagnosis of unilateral foot-drop of central neurologic origin (>6mo) who were...

A novel partially implantable system for correction of foot drop has been developed and is being tested in three volunteer subjects. The system consists of a two-channel implantable stimulator, a multi-polar nerve cuff electrode implanted on the peroneal nerve proximal to the knee, and an external system including battery, control and telemetry unit and a heel switch. Although the work is still...

Foot drop usually results from lesions affecting the peripheral neural pathway related to dorsiflexor muscles, especially the peroneal nerve. Although a central nervous system lesion is suspected when there is a lack of clinical evidence for a lower motor neuron lesion, such cases are extremely rare. We describe a patient with sudden isolated foot drop caused by a small acute cortical infarctio...

Neuromuscular disorders associated with hyperthyroidism have several variations in their clinical phenotype, such as ophthalmopathy, periodic paralysis, and thyrotoxic myopathy. We herein report an unusual case of thyrotoxic myopathy presenting as unilateral drop foot. Histopathological examinations of the left tibialis anterior muscle showed marked variation in the fiber size, mild inflammator...

Analysis of foot movement is essential in the treatment and prevention of foot-related disorders. Measuring the in-shoe foot movement during everyday activities, such as sports, has the potential to become an important diagnostic tool in clinical practice. The current paper describes the development of a thin, flexible and robust capacitive strain sensor for the in-shoe measurement of the navic...
