Douleur neuropathique chronique sévère : Un ensemble de traitements, utilisant la stimulation de la moelle épinière et un traitement multidisciplinaire, pour réduire la douleur et améliorer la fonction physique. (SCS-R)
Optimisation du traitement de la douleur neuropathique chronique : Une conception expérimentale de cas unique répliquée évaluant un ensemble de traitement comprenant une réadaptation multidisciplinaire et une stimulation de la moelle épinière (SCS-R)
Les personnes atteintes de lésions nerveuses peuvent développer des douleurs neuropathiques. La douleur peut parfois être intense et imprévisible, provoquant des sensations étranges ou alarmantes - par exemple, des sensations semblables à des éclairs ou à des chocs électriques dans la zone desservie par le nerf endommagé.
Nous examinerons un traitement pour les douleurs neuropathiques dans les jambes causées par des lésions nerveuses, qui peuvent survenir après une hernie discale ou une fracture osseuse, avec ou sans chirurgie.
Des recherches antérieures suggèrent que la stimulation de la moelle épinière peut soulager les douleurs neuropathiques dans les jambes après une chirurgie ou une blessure, mais son efficacité fait encore débat. D'autres études montrent que le traitement multidisciplinaire aide les personnes souffrant de douleurs chroniques à améliorer leur qualité de vie et à mieux faire face à la vie. Les recommandations nationales et internationales préconisent ce type de prise en charge multidisciplinaire pour les douleurs chroniques.
Personne n'a encore publié de recherche sur la stimulation de la moelle épinière associée à un traitement multidisciplinaire en tant qu'intervention groupée. Nous souhaitons donc déterminer si cette approche combinée peut réduire les douleurs neuropathiques dans les jambes et améliorer le fonctionnement physique.

Description détaillée
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

Plan pour les données individuelles des participants (IPD)
Prévoyez-vous de partager les données individuelles des participants (DPI) ?
Description du régime IPD
Les données individuelles des participants pour toutes les variables collectées, générées au cours de l'étude et entièrement documentées dans un dictionnaire de données accompagnant (détailant les noms des variables, codes, valeurs, unités et dérivations), seront mises à disposition sur demande raisonnable de chercheurs qualifiés après la publication. L'accès sera restreint aux chercheurs qualifiés qui soumettent une demande et obtiennent l'approbation du comité d'éthique pertinent et de l'autorité de protection des données.
Les identifiants directs et indirects – y compris les noms, les dates exactes et autres risques de ré-identification – seront systématiquement supprimés ou transformés (par exemple en ajustant les dates par index pour conserver les intervalles tout en empêchant le lien), garantissant ainsi que l'ensemble de données supporte des analyses secondaires robustes tout en préservant la confidentialité des participants.
Le protocole de l'étude est prévu d'être publié.
