Ernstige Chronische Neuropathische Pijn: Een Behandelbundel, Met Gebruik van Ruggenmergstimulatie en Multidisciplinaire Behandeling, om Pijn te Verminderen en Fysieke Functie te Verbeteren. (SCS-R)
Optimalisatie van de behandeling van chronische neuropathische pijn: Een gerepliceerd single case experimenteel ontwerp voor de evaluatie van een behandelingstraject bestaande uit multidisciplinaire revalidatie en ruggenmergstimulatie (SCS-R)
Mensen met zenuwschade kunnen zenuwpijn ontwikkelen. De pijn kan soms ernstig en onvoorspelbaar zijn, wat vreemde of alarmerende sensaties veroorzaakt - bijvoorbeeld bliksemachtige of elektrische schokgevoelens in het gebied dat wordt bediend door de beschadigde zenuw.
We zullen een behandeling onderzoeken voor zenuwpijn in de benen veroorzaakt door zenuwschade, die kan optreden na een hernia of een botbreuk, met of zonder operatie.
Eerder onderzoek suggereert dat ruggenmergstimulatie zenuwpijn in de benen na een operatie of letsel kan verlichten, maar de effectiviteit ervan wordt nog steeds bediscussieerd. Andere studies tonen aan dat multidisciplinaire behandeling mensen met langdurige pijn helpt hun kwaliteit van leven te verbeteren en beter in het leven om te gaan. Nationale en internationale richtlijnen bevelen dit soort multidisciplinaire zorg aan voor langdurige pijn.
Niemand heeft nog onderzoek gepubliceerd over ruggenmergstimulatie gecombineerd met multidisciplinaire behandeling als een gebundelde interventie. We willen daarom uitzoeken of deze gecombineerde aanpak zenuwpijn in de benen kan verminderen en de fysieke functie kan verbeteren.

Gedetailleerde beschrijving
Single-case experimental design (SCED) with repeated measurements structured into phases is the method of this study.
Phase A1 is the pre-implantation baseline, Phase A2 is waiting time from implantation to start of the intervention (SCS+rehabilitation). Length of A2 is randomized (2-4 weeks).
Phase B is the active SCS+rehabilitation intervention and lasts for 12 weeks (for analysis split into an early B1 (week 1-5) and a later B2 period (week 8-12), and FU is the 5 week follow-up approximately 6 months after implantation.
Outcomes are measured repeatedly within these phases, allowing within-patient phase contrasts.
In general, baseline (A1) is compared with the intervention periods (B1 and B2) and with follow-up (FU). The main pre-specified contrasts for the primary outcomes are:
- For leg pain intensity A1 vs B1 is the primary comparison and A1 vs B2 is secondary, with A1 vs FU and B2 vs FU reported descriptively.
- For physical function (PROMIS-29), A1 vs B2 is the primary comparison as onset of rehabilitation effect is expected to be delayed. A1 vs B1 is exploratory, with A1 vs FU and B2 vs FU reported descriptively.
Other repeated-measures outcomes (PROMIS-29 domains and additional NRS/physical activity measures) follow the same structure, with A1 vs B2 generally defined as secondary and A1 vs FU descriptive as shown in the statistical tables

Bent u van plan om gegevens van individuele deelnemers (IPD) te delen?
Beschrijving IPD-plan
Individuele deelnemersgegevens voor alle verzamelde variabelen, gegenereerd tijdens de studie en volledig gedocumenteerd in een bijbehorende datadictionary (met details over variabelenamen, codes, waarden, eenheden en afleidingen), zullen beschikbaar worden gesteld op redelijk verzoek van gekwalificeerde onderzoekers na publicatie. Toegang zal worden beperkt tot gekwalificeerde onderzoekers die een aanvraag indienen en goedkeuring verkrijgen van de relevante ethische commissie en gegevensbeschermingsautoriteit.
Directe en indirecte identificatoren - inclusief namen, exacte data en andere heridentificatierisico's - zullen systematisch worden verwijderd of getransformeerd (zoals indexaanpassing van data om intervallen te behouden terwijl koppeling wordt voorkomen), waardoor de dataset robuuste secundaire analyses ondersteunt terwijl de privacy van deelnemers wordt gewaarborgd.
Het studieprotocol is gepland om gepubliceerd te worden.
