Registered outcomes11
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change in Center of Mass-Center of Pressure (COM-COP) Separation Distance | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | The COM-COP separation distance will be determined from the 3D-motion capture data. The participants will be asked to walk at a self-selected/comfortable pace and to crossover a 20-centimeter-high obstacle placed in the middle of the walkway (5 trials; averaged reported in meters). |
| Primary | Change in Clearance Distance Height | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | The clearance distance of the toe and heel will be determined from the 3D-motion capture data. The participants will be asked to walk at a self-selected/comfortable pace and to crossover a 20-centimeter-high obstacle placed in the middle of the walkway (5 trials; averaged reported in centimeters). This distance will be determined by the marker position of the heel/toe away from the top of the obstacle. |
| Secondary | Montreal Cognitive Assessment (MoCA) | baseline | The participants will be administered a set of instructions and be asked to perform a series of cognitive and motor tasks. The total time to administer the MoCA is approximately 10 minutes. The total possible score is 30 points. |
| Secondary | Change in Balance, Lower-limb Muscle Strength | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Balance and lower-limb muscle strength will be assessed using the Single-leg Stance Test with Eyes Open (SLO) and Closed (SLC). The participant will be asked to stand for as long as possible up to 60 seconds, with either eyes open or closed. Trials will be terminated if the participant loses his or her balance, or if his or her feet are moved from the initial position (randomized order; 3 trials; averaged time of trials reported in second). |
| Secondary | Change in Mobility | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Mobility will be assessed using the Timed Up and Go (TUG) test. The participants will be instructed to stand up from a chair, walk 3 meters as quick and safely as possible, cross a line marked on floor, turn around, walk back, and sit down (3 trials; time of each trial recorded in seconds). |
| Secondary | Change in Mental Flexibility | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Mental flexibility will be assessed using the Wisconsin Card Sorting Test (WCST). The participants will be given a deck of 64-cards and will be asked to sort the cards by shape, color, or number. The number of errors made, and number of successful sorted categories (maximum of 6) will be recorded (3 trials; number of errors made recorded). |
| Secondary | Change in Processing Speed | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Processing speed will be assessed using the Trail Making Test Part B (TMT-B). The participants will be given a set of numbers and letters that they will be asked to connect with lines the numbers to letters in ascending order. The time that it takes the participant to complete this task will be recorded (3 trials; completion time of each trial recorded in seconds). |
| Secondary | Change in Mental Switching | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Mental switching will be assessed with the Stroop Test. The participants will be asked to name the color but not to read the word on a card. A color-word score will be given based on the total correct identification of the correct color within 45 seconds (3 trials; the total score scored out of 40). |
| Secondary | Change in Walking Speed | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Walking speed will be determined from the 3D-motion capture data collected along an 8-meter-long walkway. The participants will be asked to walk along the walkway at self-selected/comfortable pace (5 trials; averaged reported in m/s). |
| Secondary | Change in Walking Cadence | baseline, 6 weeks (mid-intervention), and 12 weeks (post-intervention) | Walking cadence will be determined from the 3D-motion capture data collected along an 8-meter-long walkway. The participants will be asked to walk along the walkway at self-selected/comfortable pace (5 trials; averaged reported in steps or cycles/min). |
