Peripheral pain management

1. A system configured to treat peripheral pain, the system comprising:

a processor configured to be coupled to an electrical lead operably coupled to an electrode configured to sense electrical activity in a patient, the processor configured to:

detect a pain signature associated with peripheral nerve damage in the sensed electrical activity;

determine a treatment protocol in response to the detected pain signature; and

cause the treatment protocol to be delivered to a sensory thalamus contained within the patient via the electrical lead and electrode implantable within the sensory thalamus, the treatment protocol including providing at least one electrical signal to the patient, the electrical signal comprising one or more electrical pulses being at least about 150 Hz, between about 1 and about 3 volts, between about 1 and about 3 milliampere, and between about 0.25 and about 1 second in duration.

2. A system configured to treat peripheral pain, the system comprising:

a processor configured to provide an electrical treatment protocol to a sensory thalamus contained within a patient, the electrical treatment protocol being configured to treat chronic pain in the patient, the treatment protocol including providing at least one electrical signal to the patient using an electrical lead operably coupled to an electrode implantable within the sensory thalamus, the electrical signal comprising one or more electrical pulses being at least about 150 Hz, between about 1 and about 3 volts, between about 1 and about 3 milliampere, and between about 0.25 and about 1 second in duration.

3. A method of identifying a subject having chronic pain of peripheral origin and related to peripheral nerve damage, the method comprising detecting, using an electrical lead operably coupled to an electrode implantable within a sensory thalamus and using a pattern recognition processor, a pain signature associated with the peripheral nerve damage and comprising a pattern of neuronal firing, said pattern comprising an elevated evoked response to stimuli, rhythmic after-discharge signaling, and increased spontaneous background firing.

4. A method of preventing or reducing pain perception, comprising identifying a subject according to claim 3 , and administering to said subject at least one electrical signal to a sensory thalamus contained within the subject, the electrical signal comprising one or more electrical pulses being at least about 150 Hz, between about 1 and about 3 volts, between about 1 and about 3 milliampere, and between about 0.25 and about 1 second in duration.

5. The method of claim 3 , wherein chronic pain further comprises one or more of: monoradiculopathies, trigeminal neuralgia, postherpetic neuralgia, phantom limb pain, complex regional pain syndromes, sciatica, and a peripheral neuropathy.

6. The method of claim 3 , wherein the peripheral nerve damage comprises inflammation of a nerve.

7. A method of identifying a subject having chronic pain of peripheral origin and related to peripheral nerve damage, the method comprising detecting, using an electrical lead operably coupled to an electrode implantable within a sensory thalamus and using a pattern recognition processor, a pain signature associated with the peripheral nerve damage comprising a pattern of burst-firing, each burst of said burst firing comprising at least 10 times the number of spikes compared to a control non-pain pattern, said burst firing comprising:

(a) a maximum interval signifying burst onset (6 ms);

(b) a maximum interspike interval (9 ms);

(c) longest increase in interspike interval within a burst (2 ms); or

(d) a minimum number of spikes within a burst (2).
