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.
|Condition or disease||Intervention/treatment||Phase|
|Amnestic Mild Cognitive Impairment||Behavioral: mSIM intervention plus activity monitoring Behavioral: Activity monitoring||Not Applicable|
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.
|Study Type :||Interventional (Clinical Trial)|
|Estimated Enrollment :||30 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||The study will include two arms: Arm 1: activity monitoring only control (CON), Arm 2: active intervention with mSIM program (mSIM) plus activity monitoring (via Fitbit), to evaluate the efficacy of the mSIM intervention on memory performance and everyday functioning. The 'Activity monitoring only' arm will serve as the control group. Study objectives include measuring treatment related changes in memory performance and everyday functioning along with putative biomarkers of the behavioral changes.|
