The near-nerve sensory nerve conduction in the medial and lateral plantar nerves was studied in 25 cases of tarsal tunnel syndrome. Sensory nerve conduction was abnormal in 24 cases (96%) The most common abnormalities were slow nerve conduction velocities and dispersion phenomenon (prolonged duration of compound nerve action potentials). These two electrophysiological abnormalities are indicati...

OBJECTIVE To assess the prevalence of isolated findings of abnormalities leading to entrapment of the lateral plantar nerve and respective branches in patients complaining of chronic heel pain, whose magnetic resonance imaging exams have showed complete selective fatty atrophy of the abductor digiti quinti muscle. MATERIALS AND METHODS Retrospective, analytical, and cross-sectional study. The...

Mechanoreceptors of foot sole likely contribute in the reflex regulations. Stimulation of these receptors in the lateral aspect of the foot is corresponded to the lateral plantar division of the tibial nerve. Therefore, it was hypothesized that repetitive low threshold afferents stimulation would have an inhibitory effect on the soleus H-reflexes. Methods: Sixteen normal subjects voluntarily...

BACKGROUND As a potential new treatment for overactive bladder (OAB), we investigated the feasibility of non-invasively activating multiple nerve targets in the lower leg. METHODS In healthy participants, surface electrical stimulation (frequency = 20 Hz, pulse width = 200 μs) was used to target the tibial nerve, saphenous nerve, medial plantar nerve, and lateral plantar nerve. At each locati...

A retrospective review was conducted in 28 patients (31 feet) with recalcitrant infero-medial heel pain, to assess the clinical outcome of a combined release of the first branch of the lateral plantar nerve and the plantar fascia. All patients were questioned by telephone interview on their pre- versus post-operative level of pain and function (based on the Kitaoka mid-foot scale and the visual...

Proximal metatarsal pain is most commonly caused by desmopathy or enthesopathy of the proximal part of the suspensory ligament. Diagnosis of the causes of proximal metatarsal pain has improved markedly with the use of more specific regional analgesic techniques, objective techniques of lameness quantification, and cross-sectional imaging methods. However, even diagnostic anesthesia of the deep ...

BACKGROUND Standard tibial motor nerve conduction measures are established with recording from the abductor hallucis. This technique is often technically challenging and clinicians have difficulty interpreting the information particularly in the short segment needed to assess focal tibial nerve entrapment at the medial ankle as occurs in posterior tarsal tunnel syndrome. The flexor hallucis bre...

One of the two peripheral nerves which innervate rat lumbrical muscle was stimulated chronically in vivo during the postnatal period of synapse elimination to determine whether the differential stimulation would affect the outcome of the elimination process. Rats were anesthetized for about 4 hr a day for 5 to 6 consecutive days, during which time the sural nerve (or, in other animals, the late...

Ankle movements in the frontal plane are less prominent though not less relevant than movements in the plantar or dorsal flexion direction. Walking on uneven terrains and standing on narrow stances are examples of circumstances likely imposing marked demands on the ankle medio-lateral stabilization. Following our previous evidence associating lateral bodily sways in quiet standing to activation...

AIM To investigate the diagnostic significance of foot plantar pressure distribution abnormalities in patients with diabetic peripheral neuropathy (DPN). PATIENTS AND METHODS A total of 107 patients were divided into normal control (28 participants, 56 feet), non-DPN (56 patients, 112 feet), and DPN groups (23 patients, 46 feet). Foot plantar pressure was measured while patients walked at a c...
