November 5, 2019 updated by: Cemka-Eval

Two-years Follow-up of Post-spinal Implantable Neurostimulator PRECISION®

Assessing the long-term efficacy, complications, revision rates and final explantation of the device

Study Overview

Detailed Description

Longitudinal study with a follow-up of 2 years in patients implanted with the Precision neurostimulator.

This study will describe the characterisrics of the patients, of the implantation and will assess the long-term efficacy, complications, revision rates and final explantation of the device

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Implanted Patients (de Novo Implants) With an Improvement of at Least 50% of the Overall Average Pain Over the Last 8 Days, Evaluated by Numerical Scale at the First Follow-up Visit, at 1 Year, and 2 Years.
Time Frame: From baseline until the end of the study at 24 months.
Percentage of patients (de novo implants) having a reduction of usual pain over the past 8 days of at least 50% at 12 and 24 months. The pain was measured with a numerical scale from 0 to 10 (0 = no pain and 10 = most intense pain). This data has been provided by 71 patients at 1 year and by 70 patients at 2 years.
From baseline until the end of the study at 24 months.
Average Pain Score Over the Last 8 Days, Evaluated by Numerical Scale at 1 Year, and at 2 Years.
Time Frame: From baseline until the end of the study at 24 months.
The pain was evaluated with a numerical scale from 0 to 10. 0 = no pain and 10 = most intense pain. This data has been provided by 71 patients at 1 year and by 70 patients at 2 years.
From baseline until the end of the study at 24 months.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Implanted Patients (de Novo Implants) With an Improvement of at Least 30% of the Overall Average Pain, Evaluated by Numerical Scale
Time Frame: From baseline until the end of the study at 24 months

Percentage of implanted patients (de novo implants) with an improvement of at least 30% at 12 and 24 months after inclusion for:

  • pain at the present time
  • usual pain over the past 8 days
  • the most severe pain in the last 8 days
From baseline until the end of the study at 24 months
Patients' Opinion on the Evolution of Pain
Time Frame: From baseline until the end of the study at 24 months
- Pain relief compared to what the patient with a de novo implant, felt before the implantation at 12 months and at 24 months.
From baseline until the end of the study at 24 months
Evolution of the Use of Other Pain Treatments
Time Frame: From baseline until the end of the study at 24 months
Rate of primary implanted patients who took at least one analgesic treatment at each follow-up (at 1 year and at 2 years)
From baseline until the end of the study at 24 months
Evolution of Quality of Life (SF-12) - Physical Score
Time Frame: From baseline until the end of the study at 24 months
Percentage of de novo patients with an increase of SF-12 (Short-Form health survey) physical score at 12 and 24 months. An increase of this score indicates an improvement in physical "quality of life.
From baseline until the end of the study at 24 months
Patients' Willingness to Restart the Treatment
Time Frame: From baseline until the end of the study at 24 months
Patients' willingness to restart the treatment at 12 months and at 24 months.
From baseline until the end of the study at 24 months
Percentage of Patients With Anxiety and Depression Disorders
Time Frame: From baseline until the end of the study at 24 months
Evolution of the rate of patients with anxiety and depression disorders at12 and 24 months.
From baseline until the end of the study at 24 months
Evolution of Quality of Life (SF-12) - Mental Score
Time Frame: From baseline until the end of the study at 24 months
Percentage of de novo patients with an increase of SF-12 (Short-Form health survey) mental score at 12 and 24 months. An increase of this score indicates an improvement in mental "quality of life.
From baseline until the end of the study at 24 months
Evolution of the Use of Level 3 Analgesics
Time Frame: From baseline until the end of the study at 24 months
Mean posology of level 3 analgesics at each follow-up (at 1 year and at 2 years). The posology was estimated in oral morphine equivalent dosage. At 1 year, 14 patients had a level 3 analgesic and at 2 years 18 patients had this type of analgesic. The posology was available for respectively 4 and 16 patients
From baseline until the end of the study at 24 months
