METHODS AND PROTOCOLS IN PERIPHERAL NERVE REGENERATION EXPERIMENTAL RESEARCH: PART IV-KINEMATIC GAIT ANALYSIS TO QUANTIFY PERIPHERAL NERVE REGENERATION IN THE RAT

Functional recovery is one of the primary goals of therapeutic intervention In peripheral nerve research. The number an diversity of tests which have been used to assess functional recovery after experimental interventions often makes it difficult to recommend any particular indicator of nerve regeneration. Functional assessment after sciatic nerve lesion has long been focused on walking track analysis; however, it is important to note that the validity of the sciatic functional index has been questioned by several researchers. In the last decade, several authors have designed a series of sensitive quantitative methods to assess the recovery of locomotor function using computerized rat gait analysis. The objective of the present review is to provide a helpful tool for the peripheral nerve investigator, by integrating the most important gait kinematic measures described in the literature that can be gathered with this technology.
