Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After being informed of the study and potential risks, all patients giving informed consent will undergo a focused phone interviews, followed by screening to determine eligibility. Participants that meet inclusion criteria will undergo baseline cognitive function testing via video (following NIH toolbox guidelines for remote cognitive function assessment), followed by a one week measurement of sedentary time using a physical activity monitor (actigraphy). At week 0, participants will be randomized into either a physical activity group to break up sedentary time or activity guidelines only in a 1:1 ratio. Follow up occurs at 6 weeks using the same measures as baseline.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Ecological Momentary Intervention
Participants will receive real time physical activity notifications via a wearable activity tracker and smartphone application.
Behavioral: Ecological Momentary Intervention
Participants will wear a Fitbit that has been programmed to deliver a notification (a buzz) when activity has ceased for more than 10 minutes. They will receive suggestions on their Illumivu mEMA smartphone app on how to replace sitting time with PA such as standing up 5 times or taking 20 steps, or even performing a short (20 seconds) preferred dance routine. Fitbit data will be captured in real-time via the iCardia platform. Participants will receive reminders from their smartphones to enter real-time feedback on activity options selected and how successful they were in adopting the option. These data will allow tracking of underlying preferences for behaviors and to tailor the program accordingly.
Other Names:
  • Illumivu mEMA
No Intervention: Physical Activity Guidelines
Participants will be sent general guidelines for disruption of sedentary time.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Sedentary Bouts
Time Frame: Baseline, 6 weeks

Change in number of bouts of sedentary activity at 6 weeks from baseline. One sedentary bout is defined as a 10 minute bout or longer where the activity count is less than 99 counts per minute.

Sedentary Bout Parameters Minimum Length: 10 Minutes Minimum Count Value: 0 Counts Per Minute Maximum Count Value: 99 Counts Per Minute
Baseline, 6 weeks
Time in Sedentary Bouts
Time Frame: Baseline, 6 weeks
Change from baseline to 6 weeks in minutes spent in sedentary bouts
Baseline, 6 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Trail Making Test A
Time Frame: Baseline, 6 weeks
Measure of pschycomotor speed. Subjects connect a series of encircled numbers in numerical order. The score is the time in seconds it takes the subject to complete the test. A lower score/time is better. Outcome is change in time to completion of TMT-A in seconds from baseline to 6 weeks.
Baseline, 6 weeks
Trail Making Test B
Time Frame: baseline, 6 weeks
Measure of executive function. Subjects connect encircled numbers and letters in numerical and alphabetical order, alternating between the numbers and letters. Score is the time in seconds it takes the subject to complete the test. A lower score/time is better. Outcome is change from baseline to 6 weeks in seconds. Lower time is better.
baseline, 6 weeks
Picture Vocabulary Test
Time Frame: Baseline, 6 weeks
A measure of general vocabulary knowledge and is considered to be a strong measure of crystallized abilities (those abilities that are more dependent upon past learning experiences and are relatively consistent across the adult life span). The respondent is presented with an audio recording of a word and four photographic images on the iPad screen, and is asked to select the picture that most closely matches the meaning of the word. This is repeated over 4 minutes. A theta score is very similar to a z-score, which is a statistic with a mean of zero and a standard deviation of one. A higher score is better
Baseline, 6 weeks
List Sorting
Time Frame: Baseline, 6 weeks
The List Sorting test requires immediate recall and sequencing of different visually and orally presented stimuli (i.e., "working memory"). Pictures of different foods and animals are displayed with accompanying audio recording and written text (e.g., "elephant"), and the participant is asked to say the items back in size order from smallest to largest, first within a single dimension (either animals or foods, called 1-List) and then on two dimensions (foods, then animals, called 2-List). List Sorting is scored by summing the total number of items correctly recalled and sequenced on 1-List and 2-List, which can range from 0-26. Higher scores indicate higher levels of working memory. Change from baseline to post-test follow-up at 6-weeks is reported.
Baseline, 6 weeks
Picture Sequence
Time Frame: Baseline, 6 weeks
A measure developed for the assessment of episodic memory. Participants are asked to recall the sequence of pictures demonstrated over two learning trials; sequence length varies from 6-18 pictures. Participants are given credit for each adjacent pair of pictures they correctly placed. The number of adjacent pairs placed correctly for each of trials 1 and 2 is converted to a theta score and a standard score is generated. Change from baseline to 6 weeks is reported. This provides a gauge of improvement or decline from one assessment to another, irrespective of demographic factors. A change in a participant's Uncorrected Standard score (or theta score) from Time 1 to Time 2 represents an absolute change in the level of performance for that individual since the previous assessment. Higher score is better.
Baseline, 6 weeks
Oral Reading Recognition Test
Time Frame: Baseline, 6 weeks
Participant is asked to read and pronounce letters and words as accurately as possible. Administrator scores them as right or wrong (number correct words is used). This test is a measure of reading decoding skill. The Reading Test is a measure of reading decoding skill and, like vocabulary, is considered among the crystallized abilities; those abilities are generally more dependent upon past learning experiences and consistent across the adult life span. Change in Reading Uncorrected score is reported and is useful in evaluating pure change in performance from one assessment to another. Higher change in Uncorrected score for Reading would mean that the participant is able to correctly identify more difficult words on the subsequent assessment, which may indicate developmental growth or a return to a previous higher level of functioning.Change from baseline to 6 weeks is reported. A higher score is better.
Baseline, 6 weeks
Crystalized Cognition
Time Frame: Baseline, 6 weeks
This composite includes the Picture Vocabulary and Reading Tests and represent an accumulated store of verbal knowledge and skills. The composite score is derived by averaging the standard scores of each of these measures, and then deriving standard scores based on this new distribution. Uncorrected standard score is generated and reported. Crystallized Cognition Composite score is considered a global assessment of individual verbal cognition. Crystallized abilities are presumed to be more dependent on experience and less on biological influences. They represent an accumulated store of verbal knowledge and skills. Higher scores indicate higher levels of functioning. Change in uncorrected standard score from baseline to 6 weeks is reported. Higher change scores indicate improved levels of functioning
Baseline, 6 weeks
Auditory Verbal Learning
Time Frame: Baseline, 6 weeks
The Rey auditory verbal learning task is a word-list learning task in which 15 unrelated words are presented orally (via audio recording) over three consecutive learning trials1. After each presentation, the participant is asked to recall as many of the words as he/she can. The Rey is scored by taking the sum of the number of words recalled across all trials (possible range is 0-45 words). The raw score is most commonly used for interpretation of the Rey test, with higher scores representing better episodic memory. Change from baseline to post-test follow-up at 6-weeks is reported.
Baseline, 6 weeks
