Art and physical activity program.

The goal of this clinical trial is to evaluate whether a combined artistic and motor activity program can reduce anxiety in children aged 8-13 with acute lymphoblastic leukemia (ALL) undergoing chemotherapy at Children's Cancer Hospital Egypt 57357. The main questions it aims to answer are: * Does participation in the program reduce anxiety compared to standard care? * Does the program improve psychological well-being, social interaction, and coping during treatment? Researchers will compare an experimental group (receiving the artistic and motor program) with a control group (receiving standard care only) to see if the intervention lowers anxiety scores on the Spence Children's Anxiety Scale. Participants will: * Be randomly assigned to either the experimental or control group. * Complete pre- and post-intervention anxiety assessments. In the experimental group: * Attend 16 weekly sessions over 4 months. * Participate in art workshops (drawing, coloring, group activities). * Engage in motor activities (warm-up, progressive exercises, relaxation, light games, treadmill/cycling up to 5 minutes). In the control group: Will not be exposed to the program, with anxiety measured before and after the same period.
