The goal of this clinical trial (prospective, comparative, and randomized double-blind study) is to learn if Reiki (a non-pharmacological intervention), when used alongside standard care, can treat and reduce postoperative pain in patients recovering from lumbar surgery (60 participants total, divided into two groups of 30).

The main questions it aims to answer are:

Does Reiki significantly reduce postoperative pain levels at day 15 (measured by a Visual Analog Scale) compared to a Sham (placebo) treatment? Does Reiki improve patient quality of life, enhance scar healing, lower daily analgesic consumption, and increase overall patient satisfaction compared to the Sham treatment?

Researchers will compare Group A (30 patients receiving Reiki sessions alongside usual care) to Group B (30 patients receiving Sham/placebo sessions alongside usual care) to see if the Reiki group experiences lower pain levels, reduced need for painkillers, better healing, and higher overall satisfaction and quality of life.

Participants will:

• Receive standard postoperative care following their lumbar surgery.
• Be randomly assigned to receive either two sessions of actual Reiki therapy or two sessions of a Sham (placebo) treatment.
• Evaluate their daily pain levels using a Visual Analog Scale (EVA).
• Complete follow-up assessments at specific intervals (Day 15, Day 21, and Day 30) to track pain levels, pain medication intake, scar healing (using a colorimetric scale), quality of life (via the SF-12 questionnaire), and overall satisfaction (via the Clinical Global Impression scale).
