About this study

Official title: DORSAL ROOT GANGLION STIMULATION AS TREATMENT FOR POSTSURGICAL GROIN PAIN (GASPA Study)

25-SMI-2014 is a post market observational, questionnaire based study to assess the effectiveness of the Axium neurostimulator as a treatment for chronic post surgical groin pain. Within is also a nested feasibility study to assess the clinical utility of a Quantitive Sensory Testing (QST) protocol in the management of the described study group.

Being tested
Implantation with the commercially available Axium neurostimulator, QST Testing

Study groupRoleWhat they receive
Treated SubjectsAll subjects recruited into the main study treated with the Axium neurostimulator
Receives: Device: Implantation with the commercially available Axium neurostimulator
QST GroupA sub-set of the main study group who also consent to take part in the Quantitative Sensory Testing based feasibility study
Receives: Device: Implantation with the commercially available Axium neurostimulator; Procedure: QST Testing

The primary outcome is the main question the study is designed to answer.

  1. Main Study: Pain Relief - Assessed be Change in Pain Intensity from Pre-Treatment Baseline

    Measured: Post implantation at; 1, 3 and 6 months

  2. Feasibility Study: To determine subject acceptance of the described QST methodology and protocol; assessed using a 5 point Likert scale

    Measured: Baseline then Post implantation at; 1, 3 and 6 months
