Objectives: This study aimed to investigate the effect of shunt operations on cervical range of motion in children with brain tumor. Methods: This study conducted at Children’s Cancer Hospital–Egypt (57357) to investigate the effect of ventriculoperitoneal shunt operation on cervical range of motion in patients with brain tumors. The inclusive criteria in this study includes, fifty patients with shunt operation, age from 6 to 16 years, 38 males and 12 females are included, cooperative patients, agreement of patient’s family (parents will sign a consent) and fair orientation and awareness. While, the exclusive criteria included, severe infections, patients who receive high dose radiation therapy, mental disorders and open or incompletely healed wounds. The patients groups used in this study includes, fifty patients having brain tumors admitted to undergo shunt operation formed an experimental group (one group study). The cervical range of motion was measured three times. One week before, two weeks before and four weeks after the operation. Neck flexion, extension, bilateral side bending and bilateral rotation movements were measured. Cervical Goniometer (CROM) used for measurements. MANOVA was used to compare the tested variables. Results: The cervical range of motion decreased slightly in side bending and rotation to both sides after two weeks from the operation. Measurements after four weeks from the operation showed significant increase in all movements.
