The length of treatment depends on the location and degree of damage to the peroneal nerve. Electrodiagnostic tests - electroneurography (ENG) are used to assess the degree of nerve damage. The nerve regenerates 1-1.5 mm a day. The precise determination of the time of the foot dorsiflexion recovery is very individual. Sometimes the foot function returns only partially and it is necessary to continue using the foot drop brace. In some cases, the foot never regains active dorsiflexion movement again.

Surgery may be considered when there is evidence of nerve damage that prevents the dorsiflexus of the foot from resuming activity. The time that has elapsed since the loss of the ability to perform active movement is of great importance - it is important that the ankle joint retains the required passive range of dorsiflexion until the operation.
