Sciatic Nerve Stretch

Peripheral Nerve Injury (PNI) Models of Neuropathic Pain

Sciatic Nerve Stretch Model of Peripheral Neuropathic Pain

 

The stretch model is a model of nerve injury that involves a later onset of functional recovery compared to the crush model.  

 

Model Specifications

  • Model length: 14-15 days
  • Readouts: tactile allodynia (von Frey), cold allodynia
  • Endpoints: histology, biomarker analysis (protein or mRNA levels in sciatic nerve or serum/plasma)

Assessments

Neurological disorders often result in a combination of motor and cognitive deficits. Thus, behavioral assessments in conjunction with physiological readouts offer a broader understanding of the basic biological mechanism of disease and cognitive impairment, highly relevant to therapeutic developments.
