. Locomotor ataxia is the inability to precisely control one's own bodily movements. Persons afflicted with this disease may walk in a jerky, up-and-down kind of rhythmical but non-fluid manner. They will not know where their arms & legs are without looking, but can, for instance, feel & locate a hot object placed against their feet. It is often a symptom of tabes dorsalis, which is a key finding in tertiary syphilis.
It is caused by degeneration of the posterior (dorsal) white column of the spinal cord.
Ref: Wikipedia.
. Progressive Locomotor Ataxia symptoms result from degeneration of the dorsal roots of the spinal cord, giving it its name, which means “dorsal wasting.” The first manifestation is usually “lightning pain,” transient, stabbing pains affecting the legs; this is followed by loss of tendon reflexes & by progressive loss of muscular coordination (ataxia) causing a spasmodic, uneven walk. Victims become unable to sense pain, limb position, & temperature; these sensory deficits cause loss of bladder & sometimes bowel control, severe foot ulcerations, & Charcot joints (an osteoarthritis that typically involves the knees & hip). Neurologic deterioration also causes the pupils of the eye to lose their ability to react to changes in light.
