mSIM: Mobile Simultaneous Aerobic Exercise and Memory Training Intervention for Older Adults With Amnestic Mild Cognitive Impairment

2019-12-10 01:21:17 | BioPortfolio


The mSIM study involves developing and conducting feasibility testing of a web-based application that will deliver mobile-based simultaneous exercise and memory skills training program (mSIM) for amnesic Mild Cognitive Impairment (aMCI) patients.

The randomized control trial (RCT) will evaluate the efficacy of mSIM on memory performance and everyday functioning using 2 study arms (Group 1 activity monitoring control (via Fitbit) (CON) vs Group 2 mSIM intervention plus activity monitoring via Fitbit). mSIM treatment response will be evaluated using neuropsychological and functional evaluation. Concentration levels of peripheral biomarkers Brain-derived neurotrophic factor (BDNF) and norepinephrine (NE) also be assessed.


The purpose of the study is to create a web-based cognitive compensatory, and predominately memory skills, training course that is delivered on a mobile device and compatible with use on a stationary bicycle and test its efficacy on memory and functional ability.

Participants will be recruited from the Pacific Brain Health Center in Santa Monica, which is a high-volume memory-care and dementia outpatient clinic within a large physician medical group affiliated with Providence Saint John's Health Center. Up to five participants will be course beta testers. They will receive a truncated version of the course and will provide detailed feedback. 30 participants will be randomized into one of two groups. Group 1 (control arm) will have their physical activity levels continuously monitored (via Fitbit). Participants will receive the Experimental Research Subject's Bill of Rights prior to signing the informed consent form (ICF), authorization of use and disclosure of protected health information (PHI), and authorization of medical record release for the subject's treating physician, will be obtained from each participants prior to enrolling in the study. A copy of all signed ICF's will be given to the participants, and the investigator will retain the original.

Group 2 (active arm) will receive the mSIM intervention plus activity monitoring (via Fitbit). Group 2 will first undergo 2 weeks of an exercise ramp-up (2x/week for 30 minutes) where they will increase their aerobic intensity from 50% by 5% each session until they reach 65% HRR and can sustain that heart rate for 40 minutes, which will be the intensity for the training. After the ramp-up phase the mSIM participants will begin the 12-week intervention, comprised of 2 60-minute sessions/week. mSIM treatment response will be evaluated using neuropsychological and functional evaluation. Assessments will occur at baseline and 17 weeks. Concentration levels of peripheral biomarkers BDNF and NE at baseline and after 17 -weeks will also be assessed.

Medical and Biotech [MESH] Definitions

Physiologic or biochemical monitoring of the fetus. It is usually done during LABOR, OBSTETRIC and may be performed in conjunction with the monitoring of uterine activity. It may also be performed prenatally as when the mother is undergoing surgery.

Measurement or recording of contraction activity of the uterine muscle. It is used to determine progress of LABOR, OBSTETRIC and assess status of pregnancy. It is also used in conjunction with FETAL MONITORING to determine fetal response to stress of maternal uterine contractions.

The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.

Simultaneous and continuous monitoring of several parameters during sleep to study normal and abnormal sleep. The study includes monitoring of brain waves, to assess sleep stages, and other physiological variables such as breathing, eye movements, and blood oxygen levels which exhibit a disrupted pattern with sleep disturbances.
