Brief Summary:
A prospective, single-arm, mono-centre pilot study to obtain preliminary information on the ability of Dorsal Root Ganglion Stimulation (DRGS) in alleviating the painful symptoms in patients with small fiber neuropathy (SFN).

Condition or disease Intervention/treatment Phase
Neuropathy Small Fibre Device: Spinal Modulation Axium™ Not Applicable

Detailed Description:
This study is a prospective, single-arm, mono-centre pilot study enrolling a maximum of 31 patients with SFN. All enrolled patients will receive a trial neurostimulation (TNS) lasting from 3 to 30 days and only patients with a positive result in terms of pain intensity reduction will be eligible for the implanted neurostimulation (INS) phase. The target number of patients eligible for INS is 10 and this population will be assessed for impact of DRGS on the neuropathic pain caused by SFN. The expected duration of patients participation will be 14 months. The rationale for this open label approach is that this is a novel technique for which pilot data with regard to applicability and efficacy have yet to be established. Data gathered in the study will provide preliminary data required to assess the feasibility of this intervention, to be used for possible future studies with a more rigorous methodological approach (i.e. controlled trial, randomized controlled trial).

Arm Intervention/treatment
Spinal Modulation Axium™
Spinal Modulation Axium™: an external trial neurostimulator (TNS) is used for the trial period, followed by an implanted neurostimulator (INS) if the TNS is successful. The TNS and INS are a pacemaker-sized devices that send out mild electrical pulses. The stimulator contains a battery and electrical components. Both TNS and INS are constant voltage devices. The TNS is used first and is worn on the outside of the clothing. The INS is implanted under the skin and support:
Device: Spinal Modulation Axium™

The participants will undergo implantation of electrodes for stimulation of fuor dorsal ganglia (Spinal Modulation, Inc., Menlo Park, CA, USA). Each participant will have one to four electrodes positioned according to the individual distribution of pain in the extremities. After implantation the electrode will be connected to an external neurostimulator: Spinal Modulation Axium™ for 3-30 days to evaluate their effectiveness (test stimulation).

If during the trial treatment the pain will decrease significantly (> 50%) a neurostimulator will be 'implanted for the continuation of the permanent neurostimulation. The neurostimulator is implanted in the abdomen in a subcutaneous pocket.

Primary Outcome Measures :
  1. Change in pain intensity assessed by Numeric Rating Scale. [ Time Frame: Pain intensity assessment during 2 weeks after inmplatation, at Time point 6 and 12 months after implantation. ]
    Four assessments/day for 5 consecutive days around the intended measurement timepoint
