Foot drop

When a soft hydrogel sphere is placed on a rigid hydrophilic substrate, it undergoes arrested spreading by forming an axisymmetric foot near the contact line, while conserving its global spherical shape. In contrast, liquid water (that constitutes greater than 90% of the hydrogel's volume) spreads into a thin film on the same surface. We study systematically this elastowetting of gel spheres on substrates of different surface energies, and find that their contact angle increases as the work of adhesion between the gel and the substrate decreases, as one would observe for drops of pure water - albeit being larger than in the latter case...

Electrical stimulators are often prescribed to correct foot drop walking. However, commercial foot drop stimulators trigger inappropriately under certain non-gait scenarios. Past researches addressed this limitation by defining stimulation control based on automaton of a gait cycle executed by foot drop of affected limb/foot only. Since gait is a collaborative activity of both feet, this research highlights the role of normal foot for robust gait detection and stimulation triggering. A novel bipedal gait model is proposed where gait cycle is realized as an automaton based on concurrent gait sub-phases (states) from each foot...

INTRODUCTION: Major pelvic Ilio-Iliac arteriovenous fistula (AVF) is an exceedingly rare diagnosis with only a few described cases in the literature, most of them related to congenital defects or trauma. In this case report, we aim to present a case of an ilio-iliac AVF with an atypical clinical presentation. CASE REPORT: The patient is a 77-year-old women, with a relevant medical history of a temporally remote hysterectomy. She developed an exuberant unilateral right leg oedema and was diagnosed with a femoro-iliac deep vein thrombosis (DVT) and started on anticoagulation and daily use of elastic compression stockings...

Background: Ankle injuries account for up to 40% of all sport related injuries. These injuries can result in weeks to months of missed sport or work. The PRICE (Protection, Rest, Ice, Compression, Elevation) treatment is standard care for most acute ankle sprains. Recently, early mobilization in adults has been shown to decrease time off from sport or work, and the likelihood of developing chronic instability. To date, no research has been performed assessing the effectiveness of early mobilization in pediatric patients (<18 years)...

In this retrospective study, a series of 10 elective patients treated with transfer of the tibialis posterior (TP) tendon for pes cavus and drop foot are described. Since TP transfer completely subtracts the role of this tendon, this cohort of patients provides an opportunity to examine the consequences of tibialis posterior (TP) deficiency. After a mean follow up period of 44.7 months, only one patient showed evidence of strain in the spring ligament but none of the patients in this series developed clinical or radiological evidence of planovalgus deformity...

BACKGROUND Acute exertional compartment syndrome (AECS) is a rare cause of leg pain often associated with a delay in diagnosis and potentially leading to irreversible muscle and nerve damage. CASE REPORT We present the case of a previously healthy, high-level athlete who presented with the acute onset of unilateral anterior leg pain and foot drop the day after a strenuous workout. He was diagnosed with compartment syndrome and rhabdomyolysis. His management included emergent fluid resuscitation, fasciotomies, debridement of necrotic muscle from his anterior compartment, and delayed primary closure...

BACKGROUND: Foot drop is a disabling clinical condition with multiplicity of causes, which requires detailed evaluation to identify the exact aetiology. Here, we report an extremely rare cause of foot drop in a child, which if not recognized early, could lead to multiple complications. CASE PRESENTATION: A 6-year-old girl presented with difficulty in walking and left sided foot droop for1-month duration. On examination she had reduced muscle power in dorsiflexors and plantar flexors and diminished knee and absent ankle jerk in the left side...

This study was to investigate the acute effects of wearing shoes on lower limb kinetics, kinematics and muscle activation during a drop jump. Eighteen healthy men performed a drop jump under barefoot and shod conditions. Vertical ground reaction force (GRF) was measured on a force plate during the contact phase of a drop jump, and GRF valuables were calculated for each condition. The angles of the knee and ankle joints, and the foot strike angle (the angle between the plantar surface of the foot and the ground during ground contact) as well as the electromyography of 7 muscles were measured...

Nurses have the most important role among health care workers (HCWs) in each hospital (Aiken et al., 2008) [1]. Nurses education can lead to the improvement of nursing care If is implemented and designed based on nurses' needs and proper principles (Aiken et al., 2008) [1]. Nowadays, increased quality of the treatment and increase the chances of survival of patients with acute respiratory failure are very important (Teixeira et al., 2013) [2]. Nursing care plan in ICU patients is one of the important elements in nursing care, and one of the main strategies is promotion of education level...

Peroneal neuropathy is a common pathology encountered by neurosurgeons. Symptoms include pain, numbness, and foot drop. When secondary to compression of the nerve at the fibular head, peroneal (fibular) nerve release is a low-risk procedure that can provide excellent results with pain relief and return of function. In this video, the authors highlight key operative techniques to ensure adequate decompression of the nerve while protecting the 3 major branches, including the superficial peroneal nerve, deep peroneal nerve, and recurrent genicular (articular) branches...

Wide-awake surgery has potential advantages for treating extensor or flexor tendon injury. We present a case of chronic extensor hallucis longus injury treated with turn-down reconstruction using wide-awake surgery with a selective nerve block. To the best of our knowledge, this is the first such case reported. The patient had dropped a knife proximal to the right hallux metatarsophalangeal joint. Because direct suturing was thought to be difficult, turn-down reconstruction was performed under a selective nerve block...
