Analysis of Spinal Cord Stimulation Usage Over a 15-Year Period


About this study

The purpose of this study is to determine the rate at which patients who underwent Spinal Cord Stimulation (SCS) trial ultimately progressed to SCS implantation, determine the percentage of patients who continued using their SCS system after 5 years, as well as identify patient characteristics that lead to SCS discontinuation.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Adults (≥ 18 years old).
  • Patients at Mayo Clinic Arizona and Mayo Clinic Minnesota who participated in spinal cord stimulator trial from January 2010 to December 2019.
  • Patients who subsequently underwent permanent implantation of spinal cord stimulator.
  • These subjects will be contacted via e-mail or telephone to complete a standardized “yes/no” questionnaire to assess current SCS usage, effectiveness of their implant, overall satisfaction, as well as determine how many patients underwent explantation.

Exclusion Criteria:

  • Individuals under 18 years old.
  • Did not participate in spinal cord stimulator trial nor undergone spinal cord stimulator implantation between January 2010 and December 2019.
