State the clinical features seen in lower motor neuron lesions

Lower motor neuron (LMN) lesions can present with a variety of clinical features, including:

1. Muscle Weakness: This is often one of the first signs of a lower motor neuron lesion. The weakness is usually most pronounced in the distal muscles, which are those furthest from the center of the body.

2. Muscle Atrophy: This is a reduction in muscle mass due to the loss of motor neurons. It can lead to visible thinning of the muscles.

3. Fasciculations: These are involuntary muscle twitches that are caused by the spontaneous firing of a lower motor neuron.

4. Hypotonia: This is a decrease in muscle tone, which can make the muscles feel soft and floppy.

5. Hyporeflexia or Areflexia: This is a decrease or absence of reflexes. It's caused by the loss of the reflex arc, which is the nerve pathway that mediates reflexes.

6. Negative Babinski's sign: Unlike upper motor neuron lesions, lower motor neuron lesions are associated with a down-going (flexor) response to the Babinski's sign test.

Remember, the exact symptoms can vary depending on the location and extent of the lesion.
