Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Gait speed- Physiological measurement of gait | Through study completion, an average of 1 year | Gait speed is measured with the Mobility Lab OPAL system (APDM, USA) consisting of three small inertial measurement units (IMU sensors including 3D accelerometers and 3D gyroscopes sampled at 128 Hz, MobilityLab, APDM Inc., Portland, OR). IMUs were attached at the participant's ankles, and lumbar region using elastic Velcro straps. These sensors are measuring gait speed (meters per second). |
| Primary | Step length- Physiological measurement of gait | Through study completion, an average of 1 year | Step length is measured with the Mobility Lab OPAL system (APDM, USA) consisting of three small inertial measurement units (IMU sensors including 3D accelerometers and 3D gyroscopes sampled at 128 Hz, MobilityLab, APDM Inc., Portland, OR). IMUs were attached at the participant's ankles, and lumbar region using elastic Velcro straps. These sensors are measuring step length (cm). |
| Primary | Cadence- Physiological measurement of gait | Through study completion, an average of 1 year | Cadence is measured with the Mobility Lab OPAL system (APDM, USA) consisting of three small inertial measurement units (IMU sensors including 3D accelerometers and 3D gyroscopes sampled at 128 Hz, MobilityLab, APDM Inc., Portland, OR). IMUs were attached at the participant's ankles, and lumbar region using elastic Velcro straps.These sensors are measuring cadence (number of steps taken in 1 minute). |
| Primary | Swing time percent- Physiological measurement of gait | Through study completion, an average of 1 year | Swing time percent (the percent of time from the total time of one gait cycle that one leg is in the air is measured with the Mobility Lab OPAL system (APDM, USA) consisting of three small inertial measurement units (IMU sensors including 3D accelerometers and 3D gyroscopes sampled at 128 Hz, MobilityLab, APDM Inc., Portland, OR). IMUs were attached at the participant's ankles, and lumbar region using elastic Velcro straps.These sensors are measuring swing time percent (unit are given in percents) |
| Primary | Electrical activity (eeg) of the brain-phisyological measure of electircal signals | Through study completion, an average of 1 year | During the walking, measure of attention recruitment during walking is applied by a single-channel EEG system (Brain-MARC LTD). The system simplifies EEG analysis to adjust the extraction of relevant attention-related markers from ongoing EEG. EEG is sampled using the MindWave dry electrode system \[25\], with one frontal electrode (∼Fpz) and one reference electrode on the earlobe. The sampled data are transferred through a wireless connection to the experiment computer, where the signal is processed. An algorithm is calaculating |
| Secondary | Cognitive function Go-NoGo Response Inhibition | Through study completion, an average of 1 year | NeuroTrax™ computerized tests assess brain wellness across an array of cognitive domains. Specifically, the Go-NoGo Response Inhibition tests abilities of Attention and Executive Function. The Go-NoGo test is a test of response time and response inhibition. Participants are presented with a series of large colored squares at variable delays. Each square may be one of four colors. Participants are instructed to respond as quickly as possible by pressing a mouse button if the square is any color but red. Outcome parameters include accuracy (i.e., percent correct), response time and its associated variance, a composite score computed as accuracy divided by response time, number of errors of omission, number of errors of commission, and response time associated with errors of commission. |
| Secondary | Cognitive function-Stroop Interference | Through study completion, an average of 1 year | NeuroTrax™ computerized tests assess brain wellness across an array of cognitive domains. Specifically, Stroop Interference tests abilities of Attention, Executive Function. The Stroop test measures response time and executive function. In the test subjects are required to say the color of the word on the screen, not what the word says. Outcome parameters include accuracy, response time and its associated variance, and a composite score computed as accuracy divided by response time. |
| Secondary | Cognitive function-Staged Information Processing Speed | Through study completion, an average of 1 year | NeuroTrax™ computerized tests assess brain wellness across an array of cognitive domains. Specifically, Staged Information Processing Speed test abilities of Attention and Information Processing Speed. The Staged Information Processing Speed test measures information processing at increasing levels of complexity. The test is comprised of three levels of information processing load: single digits, two-digit arithmetic problems (e.g., 5-1), and three-digit arithmetic problems (e.g., 3+2-1). Participants are presented with a series of digits or arithmetic problems (as per the level) and are instructed to respond as quickly as possible by pressing the left mouse button if the digit or result is less than or equal to 4 and the right mouse button if it is greater than 4. Outcome parameters for each rate increment for each level include accuracy, response time and its |
| Secondary | Cognitive function-Finger Tapping | Through study completion, an average of 1 year | NeuroTrax™ computerized tests assess brain wellness across an array of cognitive domains. Specifically, Finger Tapping tests motor skills. Participants are presented with a white rectangle, which fills with red from left to right over 12 sec. The task requires the participant to tap the left mouse button as many times as possible while the rectangle fills with red. The outcome parameters for this test include inter-tap interval and associated variance (in milliseconds) for the participant's dominant hand. |
| Secondary | Cognitive function-'Catch' Game | Through study completion, an average of 1 year | NeuroTrax™ computerized tests assess brain wellness across an array of cognitive domains. Specifically, the 'Catch' Game tests abilities of Executive Function and Motor Skills. During the 'Catch' Game participants see a rectangular white object falling vertically from the top of the screen. Their task is to "catch" the object before it reaches the bottom of the screen by positioning the rectangular green paddle directly in the path of the falling object. Responses are made with the participant's best hand. The rate of the falling object increases incrementally as the test continues making it increasingly difficult to "catch" the object in time. Outcome parameters include response time and associated variance for the first move, number of direction changes per trial, error for missed catches, and a total performance score. |
