Postural Control Under Different Cognitive Loads
“Postural Control Under Different Cognitive Loads in Adult Survivors of Acute Lymphoblastic Leukemia and Age-Matched Healthy Individuals”
The purpose of this study is to determine if adult survivors of childhood Acute Lymphoblastic Leukemia (ALL) enrolled on the SJLife (St. Jude Life) protocol are at increased risk for postural control deficits compared to individuals with no cancer history. All participants will be assessed for their ability to maintain an upright posture, walk at their usual speed, and to tandem walk, all while engaged in a cognitive task. Primary Objective To compare changes in postural control in ALL survivors to changes in postural control in healthy controls, matched on age- and sex- in simple versus complex standing and walking activities (complex: standing or walking with added cognitive load). Secondary Objective To identify demographic and performance related risk factors for decreased postural control during complex standing or walking activities in survivors and controls and to evaluate associations between treatment and the changes in postural control during complex activities among survivors.
