Split hand syndrome is a potential sign of amyotrophic lateral sclerosis (ALS). This means that some of the muscles in the hand are weak and thin (atrophied), while others are less affected.

Engineers in Germany have built a biologically inspired artificial hand with muscles made from bundles of 'smart' wires. An electric charge is all that's needed to make these wires tense or relax, ...

A biohybrid hand which can move objects and do a scissor gesture has been built by a team at the University of Tokyo and Waseda University in Japan. The researchers used thin strings of lab-grown ...

The complex combination of movements required for this simple scissor gesture is a big step up from the capabilities of previous biohybrid robots. A biohybrid hand which can move objects and do a ...

AI and human-movement research intersect in a study that enables precise estimation of hand muscle activity from standard video recordings. Using a deep-learning framework trained on a large, ...

You have 20 muscles in your forearm, the part of your arm between your elbow and your hand. They help you move your arms, hands, and fingers and perform many of the tasks of daily life. You can strain ...

Hand cramps can occur for many reasons and cause significant discomfort in some people. They are typically the result of muscle spasms or injury. Often, hand cramps are caused by muscle spasms, which ...

Biohybrid robots work by combining biological components like muscles, plant material, and even fungi with non-biological materials. While we are pretty good at making the non-biological parts work, ...

Human embryos are more muscle-bound than adult humans, new microscope images cataloging early development show. For instance, at seven weeks of gestation, embryonic hands have about 30 muscles. Adults ...

Crampy hands can make it hard to make a fist or bring your fingers together. This usually isn’t dangerous, but other symptoms may indicate an underlying condition that requires treatment. Hand cramps ...

You might get hand cramps after writing, typing, or holding your phone for long periods of time. Dehydration, diabetes, carpal tunnel syndrome, and focal dystonia can also cause hand cramps. If you ...
