简要总结
Traumatic brain injury (TBI) due to trauma and/or neurologic disease is a leading cause of long-term disability in the United States. The loss of balance for people with a traumatic brain injury can have a large effect on their walking abilities and this can come with a number of challenges. There is a greater risk of falling after being discharged from the hospital. In addition, people are more likely to become sedentary after TBI, which leads to the loss of muscle strength.
To help provide the best care, clinicians need accurate measurements when people begin their therapy, as well as throughout to ensure they are making appropriate progress. The tests currently used by clinicians may not provide the most accurate measurements that show what a person is capable of physically doing. The study you are being asked to participate in aims to provide more accurate measurements by using a robotic treadmill device and by assessing motivating factors that are important to you. The treadmill device will allow us to more accurately test your walking ability in a safe, fall-free environment.
详细描述
Traumatic brain injury due to trauma and/or neurologic disease is a leading cause of long-term disability in the United States. Balance impairments observed within the post-TBI population can greatly impact walking abilities and pose a variety of challenges. Following hospital discharge, there is a greater fall risk as well as a decrease in physical activity and increase in sedentary behaviors that lead to deconditioning.
It is difficult to determine the extent of what a person is capable of doing using current overground assessment methods, which are the current standard means of physical capability measurements (i.e. 6-minute walk test, 5 times sit-to-stand, 10-meter walk test). Improvement of walking and balance outcomes in this population requires the re-evaluation of current approaches and the testing/implementation of new approaches. This will allow more appropriate assessment of baseline walking abilities in order to apply the appropriate amount of challenge during rehabilitation training. This study will involve the use of a robotic treadmill device in order to determine maximum walking capacities of participants and compare these capacities to standard overground assessments. It has been shown that walking speeds overground are correlated with walking speeds on a robotic device (and even specifically on the KineAssist-MX, which will be used for this project). If it is found that maximum capacities be greater on the robotic device, rehabilitation training goals can be more appropriately tailored to these participants.
The aims and hypotheses of this research project are:
Aim 1) Assess function at preferred performance in an overground environment vs. a safety-enhanced robotic environment to establish concurrent validity.
Hypothesis 1) Participants with the highest overground performances (strength, speed, and endurance) will have the highest performances on the KineAssist-MX and vice versa.

结局指标
主要结局
Change in 5x Sitting to Standing Resistance Test
时间窗: Baseline, pre-intervention.
In order to measure walking strength, participants will be asked to perform a Sit-to-Stand test. Beginning from a sitting position, a participant is asked to stand and return to a seated position. They will be asked to repeat this procedure 5 times.
Change in 10-Meter Walk Test-Overground
时间窗: Baseline, pre-intervention.
The 10-meter walk test assess walking speed in meters per second over a short duration.
Top Walking Speed/Max Tolerated using Robotic Device
时间窗: During the intervention.
In order to measure walking speed, and with the assistance of the safety enhanced robotic-treadmill device, a participant's maximum walking speed will be measured in meters per second.
6-Minute Walk Test using Robotic Device
时间窗: During the intervention.
In order to measure walking endurance, participants will be asked to walk as far as they are able to comfortably walk during a 6 minute time period while using the robotic-treadmill device.
Deadband Resistance/Max Tolerated using Robotic Device
时间窗: During the intervention.
In order to measure walking strength, participants will be asked to walk on the robotic-treadmill device as fast as they can over a series of trials. Resistance of the treadmill will be increased until a maximum is reached and recorded.
6-Minute Walk Test
时间窗: Baseline, pre-intervention.
In order to measure walking endurance, participants will be asked to walk as far as they are able to comfortably walk during a 6 minute time period, with the total distance (in meters) being the outcome.
