Differential Target Multiplexed Spinal Cord Stimulation

Recruiting
Conditions
Persistent Spinal Pain Syndrome Type 2
Failed Back Surgery Syndrome
Interventions
Device: Spinal Cord Stimulation
Registration Number
NCT05068011
Lead Sponsor
Moens Maarten
Brief Summary

Evaluation of the effectiveness of differential target multiplexed spinal cord stimulation for treatment of chronic back and leg pain. Additionally, a subgroup analysis will be performed to evaluate potential differences between paddle/surgical leads versus percutaneous leads.

Primary Outcome Measures
NameTimeMethod
Overall pain intensity with Visual Analogue Scale (VAS)The change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

Overall pain, defined as a combination of back and leg pain, but not pain from other body parts, measured with the VAS (100mm)

Secondary Outcome Measures
NameTimeMethod
Clinical holistic responder statusThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months
Pain catastrophizingThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

The Pain Catastrophizing Scale (PCS) will be used to measure the level of pain catastrophizing

Symptoms of central sensitisation.The change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

The Central Sensitization Inventory is used to measure symptoms of central sensitisation

(Serious) adverse eventsThroughout study period

Systematically recording all adverse events

Proportion of successful DTM trials.Evaluated after final SCS implantation
Patient expectations concerning SCSEvaluated at baseline visit

Self-constructed open question to evaluate patient expectations about SCS

Pain medication useThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

Open question regarding the dosage, frequency and type of pain medication

Patient global impression of changeEvaluated at 1 month, 6 months and 12 months of DTM SCS.

Patients will be asked to quantify the impression of change after treatment using the Patient Global Impression of Change scale (PGIC).

Back pain intensity with Visual Analogue Scale (VAS)The change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months
Health related quality of lifeThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

Health related quality of life, evaluated with the EuroQol with five dimensions and 5 levels

Patients' individual competencies for self-managementThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

Patient activation measure-13 (PAM) is a 13-item instrument which assesses self-reported behaviour, knowledge, and confidence for self-management of one's health.

DTM SCS stimulation parametersRegistration at 1 month, 6 months and 12 months of DTM SCS
Leg pain intensity with Visual Analogue Scale (VAS)The change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months
Functional disabilityThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

The functional disabilities will be assessed with the Oswestry Disability Index (ODI)

Work statusThe change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

Work status is evaluated with a self-designed questionnaire

Anxiety and Depression.The change between the baseline screening and the evaluation 1 month after DTM stimulation, 6 months and 12 months

The hospital Anxiety and Depression Scale (HADS) will measure symptoms of anxiety and depression

Time spent in body posturesThe data will be extracted from SCS implantation up to 1 month of SCS, from 1 month of SCS up to 6 months and from 6 months up to 12 months

Based on the AdaptiveStim technology, the time spent in body postures can be recorded.

Battery consumptionRegistration at 1 month, 6 months and 12 months of DTM SCS
Healthcare utilisation.The change between implantation and evaluation at 1 month, 6 months and 12 months of DTM SCS

Postoperative healthcare expenditure will be investigated by self-reporting methods.
