NCT Number: NCT05398003

Medullary Stimulation for the Treatment of Refractory Neck Pain (S2M)

Number of centres planned : 1 (CHU Nantes)

Design : Randomized, Prospective

Planning of the study :

* Total duration: 34 months * Recruitment period: 24 months. * Follow-up time per patients : 7-10 months

Expected number of cases : 12

Treatment, procedure, combination of procedures under consideration :

During the study, patients will be implanted with the WAVEWRITER ALPHA™ system with the objective of decreasing patient pain with a spinal cord stimulation mode.

There will be a random draw on the order of the stimulation program:

* the tonic stimulation "LF": In tonic mode, the electrical stimulation of the sensory fibers of the posterior cords of the spinal cord induces local paresthesias * burst stimulation (or "burst") * high frequency" stimulation (1000 Hz) "High frequency: HF". * combined tonic + burst stimulation * combined tonic + high frequency stimulation

Treatment and study plan

Implantation of the WAVEWRITER ALPHA ™ device

Device

The 12 patients will be implanted by the WAVEWRITER ALPHA ™ device. Then, the order of the three stimulation modes will be randomly selected and will be composed of 5 modalities:

  • tonic stimulation "LF": In tonic mode, the electrical stimulation of the sensory fibres of the posterior cords of the spinal cord induces local paresthesias
  • high frequency" stimulation (1000 Hz) "High Frequency".
  • stimulation in bursts (or "Burst")

Primary outcomes

  1. Evaluating the non-inferiority of pain reduction with the combined mode compared to the low frequency reference mode.

    Time frame: 6 Months

    Comparison of the average of the visual analogic scale (scale from 0 to 10 ; 10 being the worst outcome)score collected during the 7 days of stimulation by the Tonic+Burst mode to the average of the visual analogic scale score collected during the 7 days in tonic stimulation

  2. Evaluating the overall satisfaction with the stimulation mode

    Time frame: 6 Months

    Daily collection of the patient's evaluation of his satisfaction on the remote control - the patient's logbook by a number of stars: 1* (one star) not satisfied and 5* (five stars) very satisfied

  3. Evaluating the superioty of pain reduction with the combined mode compared to the low frequency reference mode.

    Time frame: 6 Months

    Comparison of the average visual analogic scale (scale from 0 to 10 ; 10 being the worst outcome) score of the 7 days of the Tonic+Burst mode compared to the average visual analogic scale scores collected in Tonic stimulation alone.

Secondary outcomes

  1. Evaluating the non-inferiority of patient pain with the combined mode compared to the low frequency reference mode

    Time frame: 6 Months

    Comparison of the average of the visual analogic scale (scale from 0 to 10 ; 10 being the worst outcome) scores collected during the 7 days of stimulation by the combined Tonic+High Frequency mode to the average of the visual analogic scale scores collected during the 7 days of tonic stimulation.

  2. Evaluating the non-inferiority of patient satisfaction with their overall comfort

    Time frame: 6 Months

    Daily collection of the patient's evaluation of his satisfaction on the patient's notebook by a number of stars: 1* (one star) not satisfied and 5* (five stars) very satisfied. During the 7 days of stimulation by Low frequency + High frequency.

  3. Evaluating the superioty of pain reduction with the combined mode compared to the low frequency reference mode.

    Time frame: 6 Months

    Comparison of the average visual analogic scale (scale from 0 to 10 ; 10 being the worst outcome) score of the 7 days of the combined mode Tonic+ High Frequency compared to the average visual analogic scale scores collected in Tonic stimulation alone

  4. Evaluating the non-inferiority of patient satisfaction with their overall comfort with the mode low frequency + burst vs Low frequency

    Time frame: 6 Months

    Daily collection of the patient's evaluation of his or her satisfaction on the patient logbook by a number of stars: 1* (one star) not satisfied and 5* (five stars) very satisfied.
