Is Abdominal Muscle Activity Different from Lumbar Muscle Activity during Four-Point Kneeling?
Background: Stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. The four-point kneeling exercise is one of the most common types of stabilization exercises. This quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stage...
متن کاملHow regular is neuronal activity?
We propose and investigate two information-based measures of statistical dispersion of neuronal firing: the entropy-based dispersion and Fisher information-based dispersion. The measures are compared with the standard deviation. Although the standard deviation is used routinely, we show, that it is not well suited to quantify some aspects of dispersion that are often expected intuitively, such ...

متن کاملMitochondrial regular arrangement in muscle cells: a "crystal-like" pattern.
The aim of this work was to characterize quantitatively the arrangement of mitochondria in heart and skeletal muscles. We studied confocal images of mitochondria in nonfixed cardiomyocytes and fibers from soleus and white gastrocnemius muscles of adult rats. The arrangement of intermyofibrillar mitochondria was analyzed by estimating the densities of distribution of mitochondrial centers relati...
