Impact of Physical Therapy Intervention on Foot and Ankle Function

This research study will investigate the effect of physical therapy intervention on the function of the foot and ankle in children and adolescents with cancer not involving the brain or spinal cord. Children undergoing treatment for cancer can suffer from decreased flexibility, strength, balance and endurance from the cancer and from direct effects of the chemotherapy agents. These deficits have been shown to continue years after treatment end with adult survivors of cancer being less physically active then their siblings. Children, whose chemotherapy includes neurotoxic agents such as vincristine, can develop damage to their peripheral nervous system affecting the strength, sensation, and flexibility in their hands and feet. This can then lead to a change in their walking pattern and likely contributes to decreased physical activity level and fatigue. The principal investigator is currently involved in research with Dr. Laura Gilchrist and Dr. Mary C. Hooke establishing the reliability and validity of a measurement tool to quantify peripheral neuropathy, identifying physical impairments of children with cancer during treatment, and comparing physical performance in children after treatment completion with and without physical therapy intervention. The principal investigator is also completing data analysis on a pilot study investigating the use of ankle foot orthotics in children and adolescents with non-CNS cancer. In this study, the investigators will further the research by measuring the effect of physical therapy intervention on measurements involving the function and structure of the ankle and foot. The investigators will compare participants who have and have not received physical therapy intervention during cancer treatment by administering measurements detailing the function of the foot and ankle in order to further evaluate the benefit of physical therapy for children with cancer.
