We recorded whole scalp magnetoencephalographic (MEG) signals simultaneously with the surface electromyogram from upper and lower limb muscles of six healthy right-handed adults during voluntary isometric contraction. The 15- to 33-Hz MEG signals, originating from the anterior bank of the central sulcus, i.e., the primary motor cortex, were coherent with motor unit firing in all subjects and fo...

OBJECTIVE This study investigates changes in the neuromuscular activation pattern of the lower limb muscles in stroke survivors when crossing obstacles of three different heights. METHODS Eight stroke survivors and eight age-, height-, and gender-matched healthy controls were recruited and instructed to cross over obstacles with heights of 10, 20, and 30% leg length. Surface electromyography ...

introduction: estimation of stature is one of the most important fields in forensic medicine. also it is of particular interest to anthropologists and anatomist. our aim was to investigate the relationship between stature and the length of lower limb and foot to derive a regression formula for estimating the stature. methods: three anthropometric measurements stature, lower limb length (lll) an...

elephantiasis nostras verrucosa (env) is a rare condition in which hyperkeratosis, fibrosis and disfiguration of dermis occurs. it is caused mostly by non infectious diseases such as surgery, trauma, tumors, and venous obstructions. to our knowledge there is not any case report of env in middle east region. in this patient, env caused by trauma and patient presented with enlargement of right lo...

PURPOSE The constant activity of the extraocular muscles is supported by abundant mitochondria. These organelles may enhance energy production by increasing the content of respiratory complexes. The authors tested the hypothesis that extraocular muscle mitochondria respire faster than do mitochondria from limb muscles because of the higher content of respiratory complexes. METHODS Inner mitoc...

BACKGROUND Impaired balance, loss of mobility and falls are major problems associated with changes in muscle in older adults. However, the extent to which muscle composition and related performance measures for different lower limb muscles are associated with falls in older individuals is unclear. This study evaluated lower limb muscle attenuation, intramuscular adipose tissue (IMAT) infiltrati...

Focal task-specific dystonia is an unusual movement disorder that may affect musicians specifically when they perform on their instruments. Muscles of the lower face, lower limb and upper limb may be involved depending on the nature of the instrument. We illustrate the rich phenomenology of focal task-specific dystonia affecting the upper limb in musicians, and present a practical approach for ...

BACKGROUND Muscle wasting in sepsis is associated with increased proteolysis. Interleukin-15 (IL-15) has been characterized as an anabolic factor for skeletal muscles. Our study aims to investigate the role of IL-15 in sepsis-induced muscle atrophy and proteolysis. METHODS Mice were rendered septic either by cecal ligation and puncture or by intraperitoneal injection of lipopolysaccharide (LP...
