Cognitive Training in the Virtual Reality Setting With Children Undergoing Radiotherapy for Brain Tumors
Summary
The objective of this study is to estimate the feasibility and acceptability of cognitive training in the virtual reality setting with children undergoing radiotherapy for brain tumors. To achieve this goal, the investigators plan to study children undergoing radiotherapy for brain tumors randomly assigned to cognitive training administered via an iPad or virtual reality. Both groups will also participate in cognitive testing and exams using functional near infrared spectroscopy (fNIRS) pre- and post-intervention. The questions to be investigated are: 1. Will cognitive training via virtual reality be feasible and acceptable for children undergoing radiotherapy for brain tumors as indicated by participation rates, adherence and frequency of side effects? 2. Will cognitive training via virtual reality provide neurocognitive benefits? 3. Will there be predictable changes in brain activity as measured by neuroimaging? Findings from this study will be used to develop a larger, definitive trial with direct potential to improve cognitive outcomes for children treated for cancer using a safe and effective alternative to desktop- or laptop-based computerized cognitive interventions with great promise for improving quality of life.
Detailed description
The objectives of this study are: Primary Objective: • To estimate the participation rate, intervention adherence, and side effects of cognitive training in the virtual reality setting with children undergoing radiotherapy for brain tumors. Secondary Objectives: * To estimate the effect size of change in cognitive outcomes associated with cognitive training in the virtual reality setting relative to cognitive training on an iPad. * To evaluate patterns of cortical activation (oxygenated and deoxygenated hemoglobin responses) pre- and post- cognitive training in the virtual reality setting and on an iPad. The investigators will use a randomized, single blind (psychology examiner), parallel group design (cognitive training via iPad versus virtual reality) to test hypotheses about behavioral and neurophysiological changes associated with cognitive training in childhood cancer survivors. The investigators will recruit patients who are being treated for a BT with radiotherapy. Patients will participate in study sessions in the Psychology Clinic during routine visits to St. Jude for radiotherapy. fNIRS studies will be conducted with participants randomized to both the virtual reality and iPad groups pre- and post- Cogmed training sessions. The time period between pre- and post-cognitive assessments will be 2 to 4 weeks for both virtual reality and iPad groups. Participants will be enrolled until 30 patients initiating radiotherapy for a BT are evaluable, with approximately 20 randomized to the virtual reality group and 10 to the iPad group. The investigators expect to recruit and screen up to 45 patients to ascertain 30 eligible participants. Enrollment and assessment will be completed approximately 18 months after the study begins. Imaging data will be processed approximately two years after the study begins, and study findings will be disseminated within three years after the study begins. Data management and statistical analysis will be provided locally by the Department of Psychology, the Neuroimaging Division of Radiological Sciences and the Biostatistics Department at St. Jude Children's Research Hospital
Arms & interventions
- OtherCognitive training via iPad
Participants will complete five sessions of the Cogmed training program on an iPad. Participants will complete sessions over the course of one to two weeks while on campus for radiotherapy. Each session will take place in the Psychology Clinic and consist of 15 to 20 minutes of Cogmed training.
- OtherCognitive training via virtual reality
Participants will complete five sessions of the Cogmed training program within virtual reality. Participants will complete sessions over the course of one to two weeks while on campus for radiotherapy. Each session will take place in the Psychology Clinic and consist of 15 to 20 minutes of Cogmed training.
Outcome measures
Primary
Participation Rate
The participation rate of this study (i.e., how many patients agree to participate/how many patients are approached for participation) and its 90% Blyth-Still-Casella exact binomial confidence intervals will be estimated for all participants.
Time frame: After approach for enrollment, an average of 3 weeks after starting radiation therapy
Adherence
The completion of cognitive training sessions is defined as completion of four out of five planned sessions. The rate of completion of cognitive training sessions and its 90% Blyth-Still-Casella exact binomial confidence intervals will be estimated for all participants, and separately for virtual reality and iPad administration groups.
Time frame: At the completion of radiation therapy, an average of 6 weeks after enrollment
Side Effects
Summary statistics, including counts and percentages of side effects/cyber sickness symptoms will be provided at pre-, immediate-, and 1-hour post-cognitive training for participants completing training via the iPad or virtual reality.
Time frame: At the completion of radiation therapy, an average of 6 weeks after enrollment
Secondary
Neurobehavioral
Time frame: After completion of post-training assessment, an average of 8 weeks after enrollment
Cerebral Hemodynamics
Time frame: After completion of post-training assessment, an average of 8 weeks after enrollment
