重度の慢性神経障害性疼痛:脊髄刺激療法と多職種治療を用いた疼痛軽減と身体機能改善のための治療パッケージ (SCS-R)
慢性神経因性疼痛の治療最適化:多職種リハビリテーションと脊髄刺激療法(SCS-R)から成る治療パッケージを評価する反復単一事例実験デザイン
神経損傷のある人は神経痛を発症することがあります。 痛みは時には重度で予測不可能であり、奇妙なまたは警戒すべき感覚を引き起こすことがあります。例えば、損傷した神経が支配する領域での稲妻のようなまたは電気ショックのような感覚です。
椎間板ヘルニアや骨折の後、手術の有無にかかわらず発生する可能性のある神経損傷による脚の神経痛に対する治療法を検討します。
これまでの研究では、脊髄刺激が手術や損傷後の脚の神経痛を緩和できる可能性が示唆されていますが、その有効性については依然として議論されています。 他の研究では、多角的治療が長期的な痛みを抱える人々の生活の質を向上させ、生活によりうまく対処するのに役立つことが示されています。 国内および国際的なガイドラインは、長期的な痛みに対してこの種の多角的ケアを推奨しています。
脊髄刺激と多角的治療を組み合わせたバンドル介入に関する研究は、まだ誰も発表していません。 したがって、この組み合わせたアプローチが脚の神経痛を軽減し、身体機能を改善できるかどうかを明らかにしたいと考えています。
調査の概要
詳細な説明
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
