For example, Antagonistic muscle cocontraction can be either voluntary or involuntary. Additionally, because much of the legs' movements are controlled by the spinal cord and because of the larger neural delay associated with sending signals to the leg muscles, leg stiffness is more involuntarily controlled than arm stiffness.
The advantage of measuring the magnetic fields produced by neural activity is that they are likely to be less distorted by surrounding tissue (particularly the skull and scalp) compared to the electric fields measured by electroencephalography (EEG). Specifically, it can be shown that magnetic fields produced by electrical activity are not ...
Patients that experience light to mild symptoms are commonly treated through physical therapy, which involves stretching and strengthening the lower back, abdominal (core) and leg muscles. [19] Common stretches used include the knee to chest stretch, posterior pelvic tilt, neural stretching of the legs, hip-flexor stretch and lower trunk rotation.
A bone exercise monitor is an instrument which is used to measure and analyze the bone strengthening qualities of physical activity and to help in prevention of osteoporosis with physical activity and exercise. The bone strengthening quality of physical exercise is very difficult to assess and monitor due to the great variability of intensity ...
Using fNIRS, brain activity is measured by using near-infrared light to estimate cortical hemodynamic activity which occur in response to neural activity. Alongside EEG, fNIRS is one of the most common non-invasive neuroimaging techniques which can be used in portable contexts.
A bone scan or bone scintigraphy / s ɪ n ˈ t ɪ ɡ r ə f i / is a nuclear medicine imaging technique used to help diagnose and assess different bone diseases. These include cancer of the bone or metastasis, location of bone inflammation and fractures (that may not be visible in traditional X-ray images), and bone infection (osteomyelitis). [1]
Other methods which propose to measure neural activity directly have been attempted (for example, measurement of the Oxygen Extraction Fraction, or OEF, in regions of the brain, which measures how much of the oxyhemoglobin in the blood has been converted to deoxyhemoglobin [4]), but because the electromagnetic fields created by an active or ...
The method has been successfully employed to reveal functional properties of a number of neural systems, e.g. sensory systems related to touch, pain, and muscle sense as well as sympathetic activity controlling the constriction state of blood vessels. To study nerve impulses of an identified nerve, a fine tungsten needle microelectrode is ...
