Sensors to prevent pain for amputees

Amputee

Researchers at the University of Southampton have developed a new type of pressure sensor which they say could prevent damaging sores for many thousands of patients.

The technology has been funded by the Medical Research Council in a scheme to help scientists work with UK companies. It is being tried out initially with amputees, who often suffer problems caused by rubbing against their artificial limbs.

Does cracking knuckles or joints cause arthritis?

800px-Cracking_knuckles

Cracking of joints, also referred to as “popping”, is a form of joint manipulation that produces a popping or cracking sound, as may occur during knuckle-cracking, a deliberate action. People can crack several joints in their bodies, including the hips, wrists, elbows, back and neck vertebrae, toes, shoulders, feet, jaws, ankles and Achilles tendon.

Does cracking one’s knuckles cause arthritis?

Researchers from the Uniformed Services University of the Health Sciences, Bethesda, Maryland, USA, carried out a study – “Knuckle Cracking and Hand Osteoarthritis” – published in the Journal of the American Board of Family Medicine (April 2011 issue).

Senior author, Kevin deWeber, MD, FAAFP, USUHS, explained that previous studies had not shown a link between knuckle cracking and hand osteoarthritis. One study, however, suggested an inverse correlation between knuckle cracking and metacarpophalangeal joint (knuckle joint) osteoarthritis.

Dr. deWeber and team set out to determine whether knuckle cracking might be linked to hand osteoarthritis. They carried out a retrospective case-control study involving 214 people, of whom 135 had radiographically proven hand osteoarthritis and 80 did not (healthy controls). The participants were aged from 50 to 89 years; they had all received a radiograph of the right hand during the previous five years.

The researchers gathered data on the participants’ frequency, duration and details of their knuckle cracking behavior, as well as any known risk factors for osteoarthritis of the hand.

Dr. deWeber and team found that:

  • 20% of all the 215 participants cracked their knuckles regularly
  • 18.1% of those who cracked their knuckles regularly had hand osteoarthritis
  • 21.5% of those who did not crack their knuckles had hand osteoarthritis

Rückenschule zwischendurch

Um Rückenschmerzen im Alter vorzubeugen ist das richtige Sitzen und auch Übungen zwischen durch sehr essentiell.

Ziel ist es vor allem die Rückenmuskulatur zu stärken und das Zusammenspiel mit den Wirbelkörpern und auch deren Vorspannung zu intensivieren.

Wenige Übungen zwischendurch zeigen dabei schon eine große Wirkung.

Carnitine, Choline, Cancer and Cholesterol: The TMAO Connection

Expanding on the subject of my upcoming appearance on The Dr. Oz Show, a landmark new article in the New England Journal of Medicine shows that choline in eggs, poultry, dairy and fish produces the same toxic TMAO as carnitine in red meat, which may help explain plant-based protection from heart disease and prostate cancer.
