Narrow cervical canal symptoms can range widely from no symptoms to gait and balance disorders to radiculaglia when there is foraminal narrowing associated with central narrowing. Discrete balance disorders may be early signs of myelopathy (posterior cords). Later, the patients suffer from proximal weakness and paresthesia of the four limbs, as well as disorders of the fine motor skills of the hands (do not manage to close buttons of shirt, difficulties with the writing, etc., on reaching the lower motor neuron). In more advanced stages, gait disturbances and even later sphincter control disorders may occur (upper motor neuron involvement).

The density of a population of living organisms is usually measured in individuals on one square km. In here we have 50 earthworms on an area of 5 square meters, thus we have 10 earthworms on every square meter. In order to get to the result we need to see first how many square meters there are in one square km. One square km has one thousand meters of length and one thousand meters of width so:
1,000 x 1,000 = 1,000,000 km²
Since we established that we have 10 earthworms on every one square meter, we just need to multiply the number of square meters with the amount of earthworms on every square meter:
1,000,000 x 10 = 10,000,000
So we have a density of 10 million earthworms per square km.
