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.

Descrição detalhada
Cognitive performance (attention and working memory) will be evaluated using the auditory N-Back test. The 0-back condition and the 2-back condition will be used. After cognitive assessment, participants will perform 3 different postural control tasks (standing balance, regular gait, and tandem gait) in a random order. Postural tasks for each participant will be determined by using random allocation envelopes.
Computerized dynamic posturography will be used to evaluate standing balance with no added cognitive load. Standing balance assessment will be repeated two more times, once with participants engaged in performing the auditory 0-back task, and then with simultaneously performing the auditory 2-back task. Regular gait at participants' preferred speed will be examined using 6 light-weight wearable inertial sensors. The regular walking assessment will be repeated with simultaneous performance of the 0-back task and then with simultaneous engagement in the 2-back task. We have also included a tandem gait (placing one foot directly in front of the other) in order to make the postural task more challenging. The wearable inertial sensors will be used to record participants' gait characteristics while tandem walking. The tandem walk assessment will be repeated once with the participant simultaneously perform the 0-back task and then with the 2-back task. The estimated required time to perform all of the assessments and with inclusion of 3 rest intervals is 2 hours.
In addition, data from the overall SJLIFE assessment will be used in analysis.

Descrição da medida |
Prazo |
---|---|---|
Regular gait speed
Prazo: Up to 1 hour
|
Regular gait will be evaluated in three different testing conditions: regular gait assessment while participants are engaged in performing a challenging cognitive task (2-back), regular gait assessment while participants are engaged in performing an easy cognitive task (0-bak) and regular gait assessment with no additional cognitive load (baseline).
In each condition, the difference in gait speed of each survivor and his/her matched control will be obtained.
Then the obtained differences at regular gait assessment with no additional cognitive load (baseline) and regular gait while performing the challenging cognitive task (2-bck) will be compared using a paired t-test.
