Currently, the management of spasticity spans in a continuum between non-invasive and invasive intervention to modulate its effects and improve patients' Quality of life and when spasticity becomes excessive and aggravates disability, functional neurosurgery can be a resource.~Neurosurgical procedures for management of spasticity are classified according to whether their effect is generalized or focal and whether they are reversible or irreversible. Procedures include intrathecal baclofen pump , spinal cord stimulation and lesioning techniques peripheral nerves , dorsal roots , spinal cord or dorsal root entry zone
Spasticity can result from a variety of causes in neural axis from which most common are cerebral palsy, strokes, cerebral haemorrhage, multiple sclerosis , traumatic brain injury and spinal cord injury and underlying mechanism is broadly due to decrease inhibition of the spinal network.~Clinical evaluation for spasticity involve series of clinical assessment , physical examination , and neurophysiological testing. quantitative evaluation of spasticity can be measured using modified Ashworth scale which is the most widely used clinical spasticity scale and can be used for various clinical conditions causing spasticity
