Oh, My Aching Back!
Electromyography (EMG)
detects the electrical
potential generated by
muscle cells, and can test
nerve function. EMG can help
physiatrists pin down the
cause of back pain in cases
such as spinal stenosis -- a

Computer Scientists Invent Typing System for Persons with Disabilities
A new system makes typing easier for persons with disabilities. Invented by computer science student Jake Wobbrock, EdgeWrite is a typing method that uses edges of a square template to guide a PDA ... > more -
Neurologists, Imaging Scientists Use Medical Physics to Spot Disease in Blood Vessels
A new brain-imaging method allows physicians to diagnose Alzheimer's before its onset. A radioactive dye is injected in the blood and travels to the brain, where it attaches to plaque deposits of ... > more -
Molecular Biologists Devise Strategy To Starve Brain Tumors
Brain tumor researchers have found that brain tumors arise from cancer stem cells living within tiny protective areas formed by blood vessels in the brain. Killing those cells is a promising ... > more -
Vascular Surgeons Lower Blood Pressure with Implanted Device
A new cell phone-sized implant can keep blood pressure in check from within the chest, just like a pacemaker controls heartbeats. When the device detects a rise in pressure, it sends electrical ... > more -
Interventional Neuroradiologists Treat Brain Strokes with New Kind of Stent
A new "wingspan" stent helps restore blood flow for patients with intracranial atherosclerotic disease, or ICAD. Surgeons insert the stent up the leg arteries, guide it to the brain, then let its ... > more -
Neurosurgeonýs Drive Propels Him From Border Fence To Faculty
Physician scientist Alfredo Quinones has come a long way since illegally entering the United States. Today he is a faculty member at Johns Hopkins University. Quinones is a respected brain surgeon ... > more -
Pediatric Neurologists Use MRI to Understand How Strokes Impair Verbal Abilities
Children who have speech-impairing strokes often learn to talk again, while adult stroke victims can lose their verbal abilities for good. By giving reading and verbal tests inside the MRI, ... > more -
Anesthesiologists Use Nerve Blocks As Alternative To General Anesthesia
Anesthesiologists use ultrasound to locate peripheral nerves, then inject a nerve numbing medication into the area. A single injection leaves a limb numb for several hours or a day. The medication is ... > more
