When you have an acute injury, your body is sending signals through the peripheral and central nervous systems and the immune system to say, hold on, I need to stop doing this so we can allow the tissue to heal, says Ericka Merriwether, a physical therapist and pain researcher at New York University. Rest, after all, is the first part of the familiar RICE therapy, which stands for rest, ice, compression and elevation.

Artificial intelligence (AI) machine learning is making a difference in assistive technology to help restore movement for the paralyzed. A new study in the American Institute of Physics journal APL Bioengineering shows how AI has the potential to restore lower-limb functions in those with severe spinal cord injuries (SCIs) by identifying patterns in brain signals captured noninvasively via electroencephalography (EEG).

In this episode of the On Coaching Podcast, Steve Magness and Jon Marcus discuss the concept of 'fit but flat,' exploring the phenomenon where athletes excel in metabolic fitness but fail to perform competitively due to a lack of neuromuscular coordination. Using examples like middle-distance runner Ingram Brion, the hosts delve into how metabolic training alone can lead to race failures.

The brain is the conductor of the orchestra, the muscles are the instruments. When your body is out of alignment, the orchestra is playing out of tune. Misalignment in the musculoskeletal system is frequently the root cause of chronic pain and the resulting poor posture.

Complex 3D structures of cells called organoids could be used to test treatments for spinal-cord damage that can lead to paralysis.

Betley and his colleagues were curious about what happens in the brain as people get stronger through exercise. They decided to focus on the ventromedial hypothalamus, a brain region that regulates appetite and blood sugar. The team then zeroed in on a group of neurons in that region that produce a protein called steroidogenic factor 1 (SF1), which is known to play a part in regulating metabolism. A previous study found that the deletion of the gene that codes for SF1 impairs endurance in mice.

The wrist is such a complex little area, Evans says, as they have evolved to allow an extraordinary range of movement while also supporting a high level of fine motor control the wrists mean we have the capacity to do both handstands and neurosurgery. It's got eight little carpal bones they're the axis of the wrist and then you've got your radius and your ulna, which are your two forearm bones, and then that joins in with your hand bones, your metacarpals, Evans says.

If we told them to look at the face, they could usually manage it. But they were mostly looking at the hands. The Prakash children eventually learn to look at faces when spoken to - usually a few months after their surgeries. Their experiences reveal that seeing doesn't come naturally the moment a person is cured of blindness. Newly-sighted people must learn to see.
