Children's Laughter and Fun Yoga as Adjunctive Pain Relief Following Chemotherapy.

The goal of this clinical trial is to learn if a home-based program that combines laughter and fun yoga can help lower pain in children receiving chemotherapy. The study focuses on children with acute lymphoblastic leukemia who experience pain during treatment with chemotherapy and steroids. The main questions this study aims to answer are: 1. Does adding laughter and fun yoga to usual care lower pain levels in children receiving chemotherapy? 2. Does this program reduce the need for strong pain medicines, such as opioids? 3. Does the program help improve mood, anxiety, and sleep during treatment? Researchers will compare children who receive laughter and fun yoga plus usual care with children who receive usual care alone to see if the program works. Participants will: 1. Be randomly assigned to either the laughter and fun yoga group or the usual care group 2. Take part in the study during a 6-day period after receiving their chemotherapy treatment 3. Have their pain measured once each day using a child-friendly pain scale 4. Have parents answer short questions about pain medicine use, mood, anxiety, and sleep The laughter and fun yoga activities are gentle, safe, and designed to be done at home with the help of a parent. All participants will continue to receive their regular medical care throughout the study.
