We have created an alternative method for facial reanimation. This new surgical procedure involves masseter muscle transposition combined with tensor fascia lata, and the zygomatic arch is used as a trochlea to achieve reconstruction of inferior facial paralysis. This method was used on five patients with facial palsy after excision of a malignant parotid tumour. Wide skin defect exposing the m...

A 27 year-old man was admitted for bilateral legs weakness and rhabdomyolysis after a prolonged sitting posture for 10 hours due to an overuse of drugs for schizophrenia. Neurological examination showed feet drop, absent ankle tendon reflexes and hypesthesia to pin-prick stimulation below knees. The straight-leg-raising test was normal. A lumbar spine MRI study did not show abnormal spinal lesi...

W eak hip muscles lead to poor hip motion, and poor hip motion can cause knee, hip, and back pain. By exercising to strengthen the hip muscles that control how your hip moves, you can reduce your pain in these parts of your body. The 2 key muscles to include in your exercise program are the gluteus maximus (the chief muscle on the back of your hip—your buttocks) and the gluteus medius (the main...

Patients with poor levator function require ptosis correction by a sling procedure. A variety of synthetic materials are available for this suspension, but there is a recognized complication rate. Autografts are less prone to infection and extrusion than alloplastic materials. Harvesting temporalis fascia has a number of advantages over the use of fascia lata and outcomes have been effective. A...

Consistency of Einstein’s gravitational field equation Gμν ∝ Tμν imposes a “conservation condition” on the T -tensor that is satisfied by (i) matter stress tensors, as a consequence of the matter equations of motion, and (ii) identically by certain other tensors, such as the metric tensor. However, there is a third way, overlooked until now because it implies a “nongeometrical” action: one not ...

T here has been a recent surge of interest in matrix and tensor factorization (decomposition), which provides meaningful latent (hidden) components or features with physical or physiological meaning and interpretation. Nonnegative matrix factorization (NMF) and its extension to three-dimensional (3-D) nonnegative tensor factorization (NTF) attempt to recover hidden nonnegative common structures...

Friction is a very old and universal issue in all mechanical systems. Since friction is non-linear, it is an ever challenging problem. Several empirical nonlinear friction models have been proposed in the technical literature. This paper does not propose any new model but it presents a new, tensor product (TP) based representation of the existing friction models which is suitable for control de...

Introduction: This study aims at investigating whether impaired anticipatory postural adjustments (APA) during gait initiation contribute to the occurrence of freezing of gait (FOG) or whether altered APAs compensate for FOG in Parkinson's disease (PD). Methods: Gait initiation after 30 s quiet stance was analyzed without and with a cognitive dual task (DT) in 33 PD subjects with FOG (PD+FOG), ...

[Purpose] This study aimed to determine the effect of varying hip flexion angle on hip muscle activity during isometric contraction in abduction. [Subjects] Twenty-seven healthy men (mean age=21.5 years, SD=1.2) participated in this study. [Methods] Surface electromyography (EMG) was recorded of the upper portion of the gluteus maximus (UGM), lower portion of the gluteus maximus (LGM), tensor f...

Sartorius (SART) and tensor fasciae latae (TFL) in the cat hindlimb are functionally heterogeneous muscles with regions that differ in their skeletal actions and electromyographic recruitment during normal activity. The topographical organization of motoneurons supplying different regions of SART or TFL has been investigated by exposing cut nerve branches supplying different peripheral territor...
