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.
The phylum Echinodermata, which contains about 6000 species, gets its name from the Greek, literally meaning âspiny skin.â This phylum exists exclusively in the sea and includes sea stars, urchins, brittle stars, and sea cucumbers. They are simple animals, lacking a brain and complex sensing organs.haracteristic of all echinoderms is the presence of an internal skeleton covered with spines and skin. The skeleton varies with the type of echinoderms. In sea stars and brittle stars, the skeleton consists of multitudes of small calcareous plates called âossiclesâ that move with one another, forming flexible joints.
