Pain is an unpleasant sensation. Some pain is short-lived and fades once the pain is treated, this is called acute pain. However, if the unpleasant sensation persisted for duration of more than 3 months and all current treatment is no longer effective to relieve the pain. This is called chronic pain and usually it impacts both physically and emotionally. Spinal cord stimulation is indicated for treatment strategy for pain associated with the following conditions:

• Failed Back Syndrome (FBS) or low back syndrome or failed back
• Radicular pain syndrome or radiculopathies resulting in pain secondary to FBS or herniated disk
• Postlaminectomy pain
• Multiple back operations
• Unsuccessful disk surgery
• Degenerative Disk Disease (DDD)/herniated disk pain refractory to conservative and surgical interventions
• Peripheral causalgia
• Epidural fibrosis
• Arachnoiditis or lumbar adhesive arachnoiditis
• Complex Regional Pain Syndrome (CRPS), Reflex Sympathetic Dystrophy (RSD), or causalgia

Patients with spinal cord injuries present with paraplegia (paralysis in the legs) and loss of bowel or bladder function. They are resigned to a life in a wheelchair and dependence on caregivers.

Spinal cord stimulation is a new technology that has been found to help patients with complete and incomplete spinal cord injuries. Spinal cord injury (SCI) was previously thought of as permanent, but recovery in the form of voluntary movement has changed that perception forever. A surgically implanted device within the epidural space of the spine can generate electric currents to stimulate locomotor-like activity.

Depending on the level of the spinal cord injury, a patient may show moderate to significant recovery of some functions to allow him to stand independently, walk with minimal assistance as well as regain some control of the bladder and bowel function. This is not muscular stimulation or pain management. The implanted epidural stimulation device locally activates nerve circuits in the spinal cord by ‘imitating‘ brain nerve signals. Within very short periods of time patients have shown remarkable responses. The device is proven safe.

Beside Parkinson’s Disease, other movement disorders include conditions such as Essential Tremor, Dystonia, Obsessive Compulsive Disorders and Epilepsy.

• Parkinson's disease: demonstrate tremor, rigidity, slowness of movement and when drugs become less effective which worsen the movement problems, troubling "off" periods when medication wears off before the next dose can be taken, troubling "on" periods when you develop medication-induced dyskinesia
• Essential tremor: a condition that causes involuntary rhythmic tremors of hands, head, voice, legs and arms, occurring both at rest and during purposeful movement
• Dystonia: involuntary movements and prolonged muscle contraction
• Obsessive compulsive disorders: symptom of anxiety, depression and do not respond to medications or other treatments
• Epilepsy
• Parkinson is a progressive disease and usually the symptoms get worse over time. The timing when to consider DBS surgery is different for each patient. There is a "window of opportunity" when DBS may be most effective for Parkinson’s disease patient. The window opens when a patient has the disease of at least 4 years duration and not adequately control despite optimal medications, having motor complications for at least 4 months or motor complications of longer-standing duration

DBS is not an option if your Parkinson's disease symptoms no longer respond to dopaminergic medications and if the patient is severely disabled even in the best "on" state.
