Registered outcomes 8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | ActivPAL monitors | Change from baseline (week 0) activity to post intervention (week 4). | Habitual sedentary and physical activity data will be recorded through the thigh-worn monitor. Information obtained from the 3 monitors will provide information regarding time spent lying, sitting (bent vs straight leg) and standing. | ClinicalTrials.gov |
| Secondary | Cognition | Change from baseline (week 0) activity to post intervention (week 4). | The computerized Stroop task will consist of the three conditions mentioned above: simple, interference, and switching. The computer program used to administer the task records accuracy and reaction time. | ClinicalTrials.gov |
| Secondary | Brain Activation: Functional Near Infrared Spectroscopy | Change from baseline (week 0) activity to post intervention (week 4). | Functional Near Infrared Spectroscopy (fNIRS) is a well-established modality of neuroimaging that can detect differences in blood-oxygen-level dependent (BOLD) signal, allowing one to make inferences on brain activity. fNIRS sensors consist of light sources that emit near-infrared light, as well as photo diodes that detect the levels of the light at the two different frequencies. As each wavelength of light is known to be absorbed differently by oxy- and deoxyhemoglobin, one can infer cerebral oxygenation via the relative absorption of each wavelength through the application of a modified beer-lambert law. The NIRScout system contains 8 LED sources and 16 detectors (optodes), which can be placed in customized configurations to measure from different regions of the brain. The sources and detectors are held in place through an elasticized cap that fastens with Velcro under the chin. | ClinicalTrials.gov |
| Secondary | Electrocardiography | Change from baseline (week 0) activity to post intervention (week 4). | Heart rate will be monitored via electrocardiography (ECG). ECG is the non-invasive, passive recording of electrical cardiac activity at the surface of the skin. This will be recorded at a sampling frequency using a dedicated data acquisition system (PowerLab, ADInstruments) and analysis software (Lab Chart, ADInstruments). | ClinicalTrials.gov |
| Secondary | Continuous Finger Blood Pressure Recording (Finapres Medical Systems) | Change from baseline (week 0) activity to post intervention (week 4). | A small cuff used to measure continuous, non-invasive blood pressure will be placed around the middle or index finger. When in use, the cuff will inflate with air and gently squeeze the finger. This will be recorded at a sampling rate of 200Hz using a dedicated data acquisition system (PowerLab, ADInstruments) and analysis software (Lab Chart, ADInstruments). | ClinicalTrials.gov |
| Secondary | Upper Arm Blood Pressure Measurements | Change from baseline (week 0) activity to post intervention (week 4). | A semi-automated patient vital signs monitor (Carescape v100®, General Electric Healthcare) will be used to record resting, seated blood pressure from the upper left arm (i.e., the brachial artery). Additional measurements will be recorded during the various rest periods. | ClinicalTrials.gov |
| Secondary | Carotid Artery Structure | Change from baseline (week 0) activity to post intervention (week 4). | Internal carotid artery intima-media thickness will be imaged on the right-side. A minimum of two minutes of beat-by-beat carotid images during supine rest, the initial tilt, and the final tilt period will be collected. | ClinicalTrials.gov |
| Secondary | Carotid Artery Function | Change from baseline (week 0) activity to post intervention (week 4). | Internal carotid artery function changes in blood flow to head-up tilt will be measured via ultrasonography. A minimum of two minutes of beat-by-beat carotid images during supine rest, the initial tilt, and the final tilt period will be collected in the right-side common carotid artery. | ClinicalTrials.gov |
