Significant reduction in simulator collisions at 12 weeks, compared to pre-surgery and two weeks post-surgery rates
More than 53,000 Americans have total shoulder joint replacement (SJR) surgery each year, and yet the effects of this surgery on a patient’s ability to safely drive a vehicle, and the appropriate recovery time before patients should return to driving, have yet to be determined.
In a new study, “Driving Performance after Total Shoulder Arthroplasty,” the driving skills of 28 shoulder replacement patients, with a mean age of 65 ±10 years, were tested at four distinct time points before, during and after surgery using a driving simulator.
The first test was conducted before surgery; a second test, 14 days following surgery; and third and fourth tests at six and 12 weeks post-surgery, respectively. The number of total simulator collisions, off-road collisions, on-road collisions, center-line crosses and off-road excursions were recorded at each trial.
Pain Visual Analog Scale (VAS) and Shoulder Pain and Disability Index (SPADI) scores also were documented, in addition to annual driving mileage and hours slept the previous night. In 28 patients, the mean number of collisions decreased from 6.2 during the first test (pre-surgery) to 5.9 at the second test (two weeks after surgery); and from 5.2 during the third test to 4.2 by the fourth and final test.
There was a statistically significant difference in the mean number of collisions between the first and fourth test. Also, patients who drove less than 1,800 miles per year incurred a greater number of collisions at the first and fourth tests, compared to patients who drove more than 8,700 miles per year.
“At risk driving behavior,” quantified as the number of center-line crosses, decreased from 20.6 during the first test to 14.8 by the fourth test. According to the study authors, patients showed improved driving performance at 12 weeks, with a significant decrease in the number of collisions in the simulated driving course compared to the tests conducted preoperatively and two weeks after surgery.
The study authors recommend that patients wait at least six weeks, and optimally 12 weeks, to resume driving following shoulder replacement surgery. Lead author disclosure.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
