Complex regional pain syndrome (CRPS) is a devastating condition often seen after foot and ankle injury and surgery. Prevention of this pathology is attractive not only to patients but also to surgeons, because the treatment of this condition can be difficult. We evaluated the effectiveness of vitamin C in preventing occurrence of CRPS in extremity trauma(More)
Many joint-depressive, neglected calcaneal fractures need distraction arthrodesis of the subtalar joint. Because the calcaneal tuberosity is usually malunited in the varus position, more distraction is required on the medial side to place the tuberosity in the everted position before insertion of a bone graft. Traditionally, a distractor is placed on the(More)
Epilepsy of the neuropsychiatric disorder is provoked from an imbalance in the long-term potentiation (LTP) versus long-term depression (LTD) of the synapses in the hippocampus. The LTP and LTD are replicated by using the Spike Timing Dependent Plasticity (STDP). Additionally, the spiking activity of the synapses in the hippocampus can be expressed by using(More)
—Epilepsy is a neurological disorder provoked from an imbalance between long-term potentiation (LTP) and long-term depression (LTD) of the synapses. This results in an abnormal synchrony of the neurons in the brain, visible in the electroencephalogram (EEG). In certain types of epilepsy such as tonic-clonic (grand mal) seizures synap-tic disturbance occurs.(More)

Many surgeons consider performing plantarflexory osteotomy when a lateral weightbearing radiograph shows an elevated first metatarsal. In our study, we clinically evaluated the first metatarsal position in terms of the forefoot-to-rearfoot relationship and radiographically evaluated the lateral intermetatarsal angle in 190 patients. We divided the subjects(More)
—The human brain is able to process the complex information. One of the reason is that the cerebellum has a particular function. This function is that the cerebel-lum copies information in the cerebrum. We focus on the function of the cerebellum. In this study, we apply such function to the artificial neu-ral network operating the Back Propagation (BP). We(More)
