Gangguan tidur mempengaruhi kualitas hidup anak yang mendapatkan kemoterapi. Penelitian bertujuan untuk mengidentifikasi pengaruh relaksasi otot progresif terhadap kualitas tidur dan efek samping kemoterapi pada anak dengan kanker. Desain penelitian randomized clinical trial dengan metode single blind, 30 anak secara random dialokasikan pada kelompok kontrol dan kelompok intervensi. Kelompok intervensi mendapat relaksasi otot progresif 2x sehari, pagi dan malam hari, 15 menit setiap sesi selama 7 hari. Kelompok kontrol mendapat tindakan keperawatan rutin. Hasil penelitian menyimpulkan tidak ada perbedaan yang bermakna pada kedua kelompok terhadap fatigue, nyeri, dan mual muntah, namun bermakna pada kualitas tidur dimana terdapat penurunan skor kualitas tidur.
