measuring and quantifying the identified or determined motor symptoms or side effects with a processor based at least in part on the signal(s) from the at least one physiological or movement sensor while the subject is wearing the diagnostic device;

entering data corresponding to the measured and quantified motor symptoms or side effects into the processor, the processor comprising an algorithm;

calculating, with the processor, a second level of DBS parameters based at least in part on the data entered into the processor;

transmitting the second level of DBS parameters to the subject'"'"'s DBS device; and

entering the second level of DBS parameters into the subject'"'"'s DBS device such that the subject'"'"'s DBS device operates under the calculated second level of DBS parameters.

2. The method of claim 1, further comprising the step of instructing the subject to perform at least one movement disorder test(s) while the subject is undergoing DBS therapy or is under the effects of DBS therapy while the subject is wearing the movement disorder diagnostic device.

3. The method of claim 2, wherein the processor identifies or determines the movement, motion or activity based at least in part on the signal(s) from the at least one physiological or movement sensor while the subject is performing the least one movement disorder test he or she is instructed to perform.

4. The method of claim 3, wherein the processor identifies or determines the motor symptoms or side effects based at least in part on the signal(s) from the at least one physiological or movement sensor and the identified or determined movement, motion or activity of the subject while the subject is performing the at least one movement disorder test he or she is instructed to perform.

5. The method of claim 1, processor identifies or determines the movement, motion or activity based at least in part on the signal(s) from the at least one physiological or movement sensor while the subject is wearing the movement disorder diagnostic device during activities of daily living.

6. A method of tuning a movement disorder therapy system comprising steps of:

having a subject wear a movement disorder diagnostic device, the subject having a deep brain stimulation (DBS) device with a first level of DBS parameters, and the movement disorder diagnostic device comprising at least one physiological or movement sensor having a signal;

identifying or determining what activity, movement or motion the subject is performing;

identifying or determining motor symptoms of a movement disorder or side effects of a treatment the subject is undergoing that the subject is suffering or has suffered based at least in part on the signal(s) from the at least one physiological or movement sensor and at least in part on the identified determined activity, movement or motion;

measuring and quantifying the identified or determined motor symptoms or side effects with a processor based at least in part on the signal(s) from the at least one physiological or movement sensor while the subject is wearing the diagnostic device;

entering data corresponding to the measured and quantified motor symptoms or side effects into the processor, the processor comprising an algorithm;

calculating, with the processor, at least two optional groups of DBS parameters based at least in part on the data entered into the processor, each optional group addressing a separate identified or detected symptom or side effect;

having the subject select one optional group of DBS parameters based on the subject'"'"'s activity, movement or motion;

transmitting the selected optional group of DBS parameters to the subject'"'"'s DBS device; and

entering the selected optional group of DBS parameters into the subject'"'"'s DBS device such that the subject'"'"'s DBS device operates under the selected optional group of DBS parameters.

7. The method of claim 6, further comprising the step of instructing the subject to perform at least one movement disorder test(s) while the subject is undergoing DBS therapy or is under the effects of DBS therapy while the subject is wearing the movement disorder diagnostic device.

8. The method of claim 7, wherein the processor identifies or determines the movement, motion or activity based at least in part on the signal(s) from the at least one physiological or movement sensor while the subject is performing the least one movement disorder test he or she is instructed to perform.
