The medial plantar nerve is the larger one of the two terminal branches of the tibial nerve, it covers most of the sole of the foot and supply multiple muscles which functioning on the toes. 

Anatomy 

General Course of Nerve:

It arises under the flexor retinaculum and runs forward deep to the abductor halluces, then it comes to lies in the interval between the abductor halluces and the flexor digitorum brevity.  

Branches:

Cutaneous branches: plantar digital nerves run to the sides of the medial three and the medial half of the fourth toe. The nerves extend onto the dorsumand supply the nail beds and the tips of the toes.

Muscular branches: it gives a branches to these four muscles, abductor hallucis, flexor digitorum brevis, the flexor hallucis brevis and the first lumbrical muscle.

Function

Innervates (sensory and motor):

See the branches section above. 

Movements produced: 

Flexion of the big toe and abduction of toes.

Physiotherapy Techniques

Palpation:

You can assess the sensation of the areas supplied by the medial plantar nerve and palpate the area that demonstrated in the image here, to check any impairment or hyper sensitivity.
