Actuator travel is the full length of motion an actuator is capable of and is important when choosing or designing systems. Linear actuators are easier to measure than rotary ones. Incorrectly rated actuators can cause loss of efficiency or serious injury. Fixed stroke actuators have pre-set ranges while others can be adjusted. Measuring stroke can […]
Aphasia is a language disorder caused by brain damage, often from a stroke. Strokes can be hemorrhagic or ischemic and cause brain cells to die, potentially leading to aphasia. Not all strokes cause aphasia, and other conditions can also damage language areas of the brain. Aphasia and stroke are two different medical conditions that occur […]
The heart pumps blood through the body, with systole and diastole being the two phases of its movement. End-systolic volume is the blood left in the heart after a contraction. Measuring these values helps identify and treat heart problems. The human heart is an involuntarily contracting muscle responsible for distributing blood throughout the body. The […]
Warning signs of a stroke include tingling in the limbs, loss of motor skills, convulsions, speech difficulties, headaches, and facial contortions. A tingling sensation and loss of motor skills are telltale signs of a severe stroke, while sporadic speech and headaches are also linked to strokes. Facial deformation is another symptom of a major stroke. […]
Aneurysms are swellings in blood vessels that can rupture, while strokes occur when blood and oxygen cannot reach parts of the brain due to vessel blockages or ruptures. Both can be fatal and affect blood vessels, but aneurysms usually occur in the aorta and may not show symptoms until they rupture, while strokes usually occur […]
The NIH Stroke Scale is a clinical rating scale used to assess the likelihood of an individual having a stroke based on their clinical examination. It evaluates motor function, cognition, sensory function, level of consciousness, vision, and speaking ability, and patients receive a score ranging from zero to 30. A low score suggests a good […]
Strokes can cause a range of aftereffects depending on their severity and location in the brain, including speech and vision difficulties, loss of mobility, and cognitive impairment. Recovery can take years, but medical advances have improved outcomes. Rehabilitation should start early to reduce the chance of permanent effects. The aftereffects of a stroke depend on […]
After a stroke, survival is the first concern, followed by rehabilitation to regain lost skills. A team of healthcare professionals will help, and reducing the risk of a second stroke is important. Intensive care should start as soon as possible, and physical therapy should continue for as long as possible. The time after a stroke […]
A stroke occurs when blood flow to the brain is reduced or stopped, causing brain cells to die. It is the third leading cause of death in the US, with 80% of strokes caused by a blocked artery. Knowing the signs of a stroke is crucial for quick medical treatment and recovery. A stroke occurs […]
Spinal cord strokes are caused by obstruction of blood flow in the spine, leading to pain, weakness, and possibly paralysis. Causes include atherosclerosis, chronic illnesses, infections, and injuries. Prompt medical attention and ongoing physical therapy can help, but severe damage may be irreversible. Emergency medical care should be sought at the first signs of a […]
Strokes can be ischemic or hemorrhagic, with 80% being ischemic. Ischemic strokes can be caused by thrombosis or embolism, while hemorrhagic strokes are caused by a ruptured vessel or severe head damage. Hemorrhagic strokes can be more deadly due to their rapid onset and severe damage. Strokes can be of two types: ischemic stroke or […]
Strokes and seizures can be linked, especially in older patients. Seizures can be caused by brain damage from a stroke, and strokes can cause seizures up to three months after the event. Hemorrhagic strokes are more likely to cause future seizures. Brain scans may be used to diagnose and treat both conditions. Strokes and seizures, […]
Doctors use various techniques, such as ultrasound and cardiac catheterization, to measure stroke volume, which is the amount of blood pumped by the heart with each beat. Normal range is 60-130 milliliters per beat, and a low volume may indicate complications. Doctors can use several techniques to measure stroke volume, which is the amount of […]
A stroke can cause loss of brain function due to lack of blood flow, resulting in limited mobility and communication skills. Physical and speech therapy can help with recovery, but some conditions such as Parkinson’s and dementia may have long-term effects. A stroke is a loss of brain function due to lack or decrease of […]
An acute stroke is a serious medical emergency that requires immediate attention. It can be caused by arterial blockage or hemorrhage and is often associated with chronic conditions such as high blood pressure and diabetes. Symptoms include impaired motor skills, coordination, and cognition, as well as unilateral weakness or paralysis. Treatment depends on the cause […]
Strokes can cause brain damage and memory loss, but rehabilitation and therapy can often reverse it. Memory loss can take many forms, and patients may develop delusions or vascular dementia. Rehabilitation can help patients recover memories and develop techniques to compensate. Stroke and memory loss are closely linked, as strokes can damage the brain and […]
A stroke can cause sudden weakness, numbness, or paralysis on one side of the body, along with headaches, confusion, and difficulty speaking. Prompt treatment is crucial to minimize brain damage. Mini strokes have similar symptoms but last for a shorter duration. Aftereffects can be temporary or permanent. Symptoms of a stroke include sudden feelings of […]
Neck cracking during chiropractic treatment can increase the risk of stroke, especially among those under 60. Studies have linked cervical artery dissection to neck cracking, which can lead to blood clots and oxygen deprivation in the brain. Patients should be aware of the risk and watch for signs of stroke after treatment. The theory that […]
Cerebral infarction, or ischemic stroke, occurs when blood flow to the brain is cut off, often due to a thrombosis or embolism. The resulting ischemic cascade can cause brain tissue damage and inflammation. Symptoms include muscle weakness, numbness, and memory impairment. Treatment involves breaking or removing the clot and supportive therapy. Cerebral infarction, also known […]
