Rare Cases Of Restored Vision Reveal How The Brain Learns To See

Results: By testing formerly blind patients within weeks of sight restoration, Sinha and his colleagues found that subjects had very limited ability to distinguish an object from its background, identify overlapping objects, or even piece together the different parts of an object. The patients gradually improved over time, and the new study suggests that dynamic information - that is, input from moving objects - is critical to the brain's ability to learn to segregate objects from their backgrounds (a task known as visual integration). Why it matters: Doctors have been hesitant to treat older patients because the conventional dogma holds that the brain is incapable of learning to see after age 5 or 6, but these findings support the idea of treating blindness in older children and adults.

Flat Feet - Part Two

In the raising up on tiptoe manoeuvre we should observe that as the calf muscle exerts its power to raise the body weight over the metatarsal heads, the heel should adopt a slight inward slant. If the tibialis posterior tendon is not functioning well this inward movement of the heel does not happen and patients may find the action difficult, painful or not possible. The physiotherapist will next check the foot up on the bed and palpate around the insertion of the tendon for pain, tenderness and swelling. Then the foot will be held in an inwards and foot down position and the patient asked to hold it there as the physio applies resistance to test the muscle power.

What Is A Fracture? What Are Broken Bones?

A fracture, also referred to as a bone fracture, FRX, FX, F x or # is a medical condition where the continuity of the bone is broke. A significant percentage of bone fractures occur because of high force impact or stress; however, a fracture may also be the result of some medical conditions which weaken the bones, for example osteoporosis, some cancers or osteogeneris imperfecta. A fracture caused by a medical condition is known as a pathological fracture. The word break is commonly used by lay (non-professional) people. Among health care professionals, especially bone specialists, such as orthopedic surgeons, break is a much less common term when talking about bones.

Physical Therapy - Fitness and Physical Therapy Go Hand in Hand

Physical therapy and a good fitness program have more similarities than one might think. In fact, the two are fairly closely linked. Both rely on strength building strength and the enhancement of flexibility in order to restore and maintain both functionality and ease of movement to one's body. They are contributing partners in healthy, active lifestyles that are pain-free. Physical therapy is an arena of medical care which uses exercise in order to heal a body. A therapist goes through a rigorous training program in order to obtain the skills necessary to treat patients. He or she may work in a hospital setting, nursing home, rehabilitation center and even an athletic club.

Scientists Make Paralyzed Rats Walk Again After Spinal-Cord Injury

UCLA researchers have discovered that a combination of drugs, electrical stimulation and regular exercise can enable paralyzed rats to walk and even run again while supporting their full weight on a treadmill. Published Nov. 20 in the online edition of Nature Neuroscience, the findings suggest that the regeneration of severed nerve fibers is not required for paraplegic rats to learn to walk again. The finding may hold implications for human rehabilitation after spinal cord injuries. "The spinal cord contains nerve circuits that can generate rhythmic activity without input from the brain to drive the hind leg muscles in a way that resembles walking called 'stepping, '" explained principal investigator Reggie Edgerton, a professor of neurobiology and physiological sciences at the David Geffen School of Medicine at UCLA.

Where to Buy Kinesio Tex Tape

Have you ever seen that weird looking tape that athletes are wearing now and wondered what it is or where you could buy it? Well, it is called kinesio tex tape and you are best off buying it online because most stores don't carry it yet. But with it's growing popularity you should be able to find it in many stores near you soon. This tape is used by the NFL, NBA and AVP. The normal taping that an athletic trainer would do causes a restriction of blood flow because it is tight. With kinesio taping you can get more blood flow because it lifts the skin to allow blood to more easily flow to the injured body part. It doesn't take a rocket scientist to realize that your recovery time is shortened when you can get more blood to the injured area of the body.
