Registered outcomes 12
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description | Source |
|---|---|---|---|---|
| Primary | Dual task cost to standing postural sway speed | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | The dual task cost to standing postural sway speed will be calculated from trials of standing with and without simultaneous performance of a serial subtraction cognitive task. The dual task cost will be calculated as the percent change in sway speed from single- to dual-task conditions. | ClinicalTrials.gov |
| Primary | Dual task cost to gait speed when walking | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | The dual task cost to gait speed when walking will be calculated from trials of walking with and without simultaneous performance of a serial subtraction cognitive task. The dual task cost will be calculated as the percent change in gait speed from single- to dual-task conditions. | ClinicalTrials.gov |
| Secondary | Dual task cost to postural sway area | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | The dual task cost to standing postural sway area will be calculated from trials of standing with and without simultaneous performance of a serial subtraction cognitive task. The dual task cost will be calculated as the percent change in postural sway area from single- to dual-task conditions. | ClinicalTrials.gov |
| Secondary | Dual task cost to gait variability when walking | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | The dual task cost to gait variability when walking will be calculated from trials of walking with and without simultaneous performance of a serial subtraction cognitive task. Gait variability will be defined as the coefficient of variation about the average stride time (stride times defined by the time between consecutive heel strides of the same leg). The dual task cost will be calculated as the percent change in gait variability from single- to dual-task conditions. | ClinicalTrials.gov |
| Secondary | Single task postural sway speed | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Single task postural sway speed will be calculated from trials of standing without simultaneous performance of a serial subtraction cognitive task. | ClinicalTrials.gov |
| Secondary | Single task postural sway area | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Single task postural sway area will be calculated from trials of standing without simultaneous performance of a serial subtraction cognitive task. | ClinicalTrials.gov |
| Secondary | Single task gait speed variability when walking | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Single task gait variability when walking will be calculated from trials of walking without simultaneous performance of a serial subtraction cognitive task. Gait variability will be defined as the coefficient of variation about the average stride time (stride times defined by the time between consecutive heel strides of the same leg). | ClinicalTrials.gov |
| Secondary | Single task gait speed when walking | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Single task gait speed when walking will be calculated from trials of walking without simultaneous performance of a serial subtraction cognitive task. | ClinicalTrials.gov |
| Secondary | Mobility | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Mobility will be assessed using the Timed Up-and-Go test in which the amount of time it takes for the participant to stand up from a chair, walk three meters, turn around a cone, walk back, and sit down is recorded. | ClinicalTrials.gov |
| Secondary | Executive function | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Executive function will be assessed using the Stroop test. | ClinicalTrials.gov |
| Secondary | Cognitive processing speed | This outcome will be assessed immediately before and after each 20-minute session of tDCS. | Cognitive processing speed will be assessed using the Symbol Digit Modalities Test (SDMT). | ClinicalTrials.gov |
| Secondary | Attention | This outcome will be assessed immediately before and after each 20-minute session of tDCS | Attention will be assessed using the Visual Search and Attention Test (VSAT). | ClinicalTrials.gov |
