Difference between UMN lesions and LMN lesions

Upper Motor Neuron lesions:

> Paralysis affects the movement of a group of muscles.
> Tone of the muscles is increased.
> No wasting of muscles.
> Fasciculations absent.
> Babiniski sign +ve.
> Clonus absent.

Lower Motor Neuron lesions:

> Individual group of muscle is paralysed.
> Tone of the muscles is decreased.
> Wasting of the affected muscles.
> Fasciculations present.
> Babiniski sign -ve.
> Clonus absent.
