1. A device for neurostimulation, the device comprising:
a pulse generator capable of generating current having pulses; and
at least one first pair of electrodes connected to said pulse generator;
the device providing at least one current parameter configuration for neurostimulation stored in the device;
said current parameter configuration being programmable by a user; and
said current parameter configuration being associated with a level paresthesia sensation of a patient, when said neurostimulation is performed by using said current parameter configuration, wherein:
said current parameter configuration includes parameters for a first pulse train with pulse amplitudes within a first range and a second pulse train with pulse amplitudes within a second range, and a therapy strength scale adjustable by the user or by a patient;
at a beginning of said therapy strength scale, a first pulse train is set on a first amplitude at a lower limit of said first range and a second pulse train is set on a second amplitude at a lower limit of said second range;
at an end of said therapy strength scale, said first amplitude is set on an upper limit of said first range, and said second amplitude is set on an upper limit of said second range;
in a low strength range of said therapy strength scale, said second amplitude is maintained, and said first amplitude increases towards or up to said upper limit of said first range;
in a high strength range of said therapy strength scale, said first amplitude is maintained at said upper limit of said first range, while said second amplitude is increased up to said upper limit of said second range; and
an increase on said therapy strength scale within or outside of said high strength range can be experienced by the patient as increasing paresthesia; and
wherein said therapy strength scale is a parameter referring to the amount of therapy the patient is receiving from a combination of programs.

10. A method for neurostimulation or pain relief, the method comprising the following steps:
applying a current to a patient;
providing the current in accordance with a current parameter configuration including parameters for:

a second pulse train having low frequency pulses with a second amplitude in a second range; and
a therapy strength scale adjustable by the patient, the therapy strength scale being a parameter referring to the amount of therapy the patient is receiving from a combination of programs;
applying the current pulses with an adjustable therapy strength, wherein:
at a lowest strength at a beginning of the therapy strength scale, the first amplitude is set on a lower limit of the first range, and the second amplitude is set on a lower limit of the second range;
at a highest strength at an end of the therapy strength scale, the first amplitude is set on an upper limit of the first range, and the second amplitude is set on a lower limit of the second range;
in the low strength range of the therapy strength scale, the second amplitude is maintained at the lower limit of the second range, and the first amplitude increase towards or up to the upper limit of the first range; and
in the high strength range of the therapy strength scale, the first amplitude is maintained at the upper limit of the first range, while the second amplitude is increased up to the upper limit of the second range.
