DRG stimulation is
safe and effective in improving pain outcomes and quality of life at 12 months
post permanent implant, however long term outcomes beyond 12 months still need
to be examined.
The severe trunk or
lower limb pain and related functional disability can be significantly managed
12-months after the implantation of the dorsal root ganglion (DRG) stimulation.
The DRG stimulation is latest neuromodulation approach, which provides
effective relief from pain with total safety for various etiologies.

Huygen and colleagues conducted a prospective observational study to assess DRG
stimulation effectiveness in real-world clinical circumstances. The patients
from multiple clinics of the Netherlands who suffered from the uncontrollable
and chronic trunk or lower limbs pain were enrolled. The outcomes involved
quality of life, rating, mood, function and pain, which was observed one year
after the implantation of DRG stimulation.
Amongst the selected
66 subjects, ineffective peripheral nerve injury, complex regional pain
syndrome and back surgery syndrome produced the biggest etiologies. A total of
56 subjects went through permanent implants. The primary area of pain was
reduced from 8.0 cm to 4.1 cm one year after the procedure. A ≥50% decrease in VAS was also noticed in about
49% of patients. The quality of life, functional capacity and mood improved as
well. The infection reduced, and no established lead migrations were noticed.
All these outcomes confirmed that DRG stimulation considerably enhanced the
functional ability and decreased the pain after 12 months of implantation.
