George (2004) found that, when compared to controls, subjects with DPN exhibited significantly lower walking velocity, and cadence, as well as impaired reaction time and ability to produce rhythmic limb acceleration (9).
Brittle stars are a moderately popular invertebrate in fishkeeping. They can easily thrive in marine tanks; in fact, the micro brittle star is a common hitchhiker that will propagate and become common in almost any saltwater tank, if one happens to come along on some live rock.
Starfishlike brittle stars have five thin arms and no central brain, but even so, they move in a carefully coordinated fashion similar to four-limbed animals (including humans). A new analysis delves into the details of brittle star locomotion. Symmetry is at the heart of the mystery of brittle star movement. Humans, and many other animals, from insects to birds, have bodies divided into two matching halves, a right and a left. Scientists describe this as bilateral symmetry. Other animals, including jellyfish and sea anemones, have bodies that can be divided into matching halves in multiple ways. This is called radial symmetry. Brittle stars fit into this category; their bodies can be divided into matching halves five different ways.
