Many stroke patients suffer from spasticity of the arm that cause pain and impaired sensorimotor function. But there are ways of identifying such patients ahead of time so that they can obtain the earliest possible treatment. Researchers at Sahlgrenska Academy have completed a study of stroke patients in the Gothenburg area.
Spasticity and related complications are relatively common after stroke, leading to poorer joint range of motion, greater pain and less sensitivity in the arm one year later.
A study at Sahlgrenska Academy, University of Gothenburg, has found that the Fugl-Meyer assessment scale, a sensorimotor test performed during the first month after stroke, predicts with a fairly high degree of accuracy the patients who will develop spasticity within one year.
Poor sensorimotor function
A total of 117 Gothenburg area patients with an average age of 67 participated in the study. All of them had experienced poorer sensorimotor function in the arm three days after first-ever stroke. Upper limb sensorimotor function, spasticity and joint range of motion were monitored over the following year.
Arve Opheim, a researcher at Sahlgrenska Academy, says, “Our findings suggest that systematic examinations of sensorimotor function can identify patients at risk of developing spasticity so that they can obtain early treatment. Opportunities for minimizing pain, impaired function and other repercussions of spasticity will inevitably follow.”
The article Early Prediction of Long-term Upper Limb Spasticity after Stroke: Part of the SALGOT Study was published in Neurology on August 14.
A FEW FACTS ABOUT SPASTICITY
Spasticity refers to a motor disorder caused by damage to the central nervous system. The spasms, which may arise following a stroke, have the potential to occasion pain as well. Anywhere from 40% to 50% of stroke patients develop upper limb spasticity.

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.
A warming planet
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
