Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in Gait Speed From Baseline to 12 Weeks Using 10 Meter Walk Test (10MWT) | The mean change in gait speed demonstrated during the 10MWT after 12 weeks of training and compared between groups. Positive values indicate improvement in gait speed (faster) from baseline to 12 weeks. Negative values indicate a reduction in gait speed (slower) from baseline to 12 weeks. | Baseline and 12 Weeks | |
Secondary | Number of Participants Who Met the Minimal Clinically Important Difference of 0.15m/s in Gait Speed Per 10 Meter Walk Test (10MWT) From Baseline to 24 Weeks | Number of participants who achieve the Minimal Clinically Important Difference (MCID) of 0.15 m/s during the 10MWT when comparing between baseline gait speed and gait speed at 24 weeks. | Between baseline and 24 weeks | |
Secondary | Change in Distance Covered Over 6 Minutes From Baseline to 24 Weeks | 6 minute walk test (6MWT) completed at baseline and 24 weeks. Change assessed. Positive values indicate an increase in distance was able to be walked at 24 weeks versus at baseline. Negative values indicate a decrease in distance was walked at 24 weeks versus at baseline. | Baseline-24 weeks | |
Secondary | Change in Time Required to Complete Timed Up and Go (TUG) Test From Baseline to 24 Week Follow up | Examined balance and walking in participants at baseline and follow up at 24 weeks. Positive values indicate an improvement of time (less time) required to complete task at 24 week follow up versus at baseline. Negative values indicate a decline, more time required to complete task at follow up versus baseline. | Baseline and 24 weeks | |
Secondary | Number of Participants Who Experienced a Fall During Protocol | At each training session, assessed if participant had experienced any falls. Count is number of participants who reported that yes, they did experience a fall. | Throughout 24 weeks | |
Secondary | Change in Berg Balance Scale Score From Baseline to 24 Weeks | Measurement of static and dynamic sitting and standing balance completed at baseline and at 24 weeks. Berg balance scale is a 14 item test with each item scored from 0-4. Possible scores range from 0-56. Higher scores indicate a lower risk of falls and better balance. Positive numbers indicate an improvement in Berg balance scale (scored out of 56), meaning that the participant scored higher at 24 weeks than at baseline. Negative values indicate a decline in performance of the Berg balance scale (scored out of 56), meaning that the participant scored lower at 24 weeks than at baseline. | Baseline-24 weeks |
