While experts disagree on whether work tasks alone can be the exact cause of work-related musculoskeletal disorders (WMSD) such as carpal tunnel syndrome, a new study by researchers at Temple University proves that a highly repetitive work task, a risk factor for WMSD, does in fact cause bone damage.
"Because multiple factors play a role in the development of WMSD, including work tasks, home activities, and medical conditions such as diabetes or heart disease, we studied work tasks alone to isolate their impact," said Ann Barr, P.T., Ph.D., associate professor of physical therapy at Temple University and the studys lead author. "This information is critical in helping industry and medicine establish workplace guidelines to prevent WMSD."
The study, "Repetitive, Negligible Force Reaching in Rats Induces Pathological Overloading of Upper Extremity Bones," published in the November 11 issue of the Journal of Bone and Mineral Research, is the third in a series conducted by a group of researchers at Temple Universitys College of Health Professions and School of Medicine. "Our studies have shown a direct relationship between repetitive, low force movement and the inflammation of muscles, bone, nerves and connective tissue typical of WMSD," said Barr.

The building blocks of matter in our universe were formed in the first 10 microseconds of its existence, according to the currently accepted scientific picture. After the Big Bang about 13.7 billion years ago, matter consisted mainly of quarks and gluons, two types of elementary particles whose interactions are governed by quantum chromodynamics (QCD), the theory of strong interaction. In the early universe, these particles moved (nearly) freely in a quark-gluon plasma.
This is a joint press release of University Muenster and Heidelberg as well as the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt.
Then, in a phase transition, they combined and formed hadrons, among them the building blocks of atomic nuclei, protons and neutrons. In the current issue of...
Thin-film solar cells made of crystalline silicon are inexpensive and achieve efficiencies of a good 14 percent. However, they could do even better if their shiny surfaces reflected less light. A team led by Prof. Christiane Becker from the Helmholtz-Zentrum Berlin (HZB) has now patented a sophisticated new solution to this problem.
"It is not enough simply to bring more light into the cell," says Christiane Becker. Such surface structures can even ultimately reduce the efficiency by...
A study in the journal Bulletin of Marine Science describes a new, blood-red species of octocoral found in Panama. The species in the genus Thesea was discovered in the threatened low-light reef environment on Hannibal Bank, 60 kilometers off mainland Pacific Panama, by researchers at the Smithsonian Tropical Research Institute in Panama (STRI) and the Centro de Investigación en Ciencias del Mar y Limnología (CIMAR) at the University of Costa Rica.
Scientists established the new species, Thesea dalioi, by comparing its physical traits, such as branch thickness and the bright red colony color, with the...
