Up to 40 participants will be enrolled in this study in order to obtain complete data on 30 participants. The investigators will be assessing if Augmented reality in combination with treadmill training is safe and feasible to use in the clinical environment with participants who have chronic TBI and if there is a signal of effect that this intervention may be more beneficial than treadmill training alone or standard of care.

| Augmented Reality | Behavioral | Augmented Reality (AR) systems are computer-based applications that allow an individual to view a simulated environment and dynamically interact within this environment in real-time. Augmented reality activities will be chosen by the therapist based on the primary deficits assessed during baseline testing. |
| Measure | Description | Time Frame |
|---|---|---|
| Community Balance and Mobility Scale | 13 activities scored from 0-96, higher numbers reflect greater balance | Baseline to Week 8 |
| Measure | Description | Time Frame |
|---|---|---|
| 10 meter walk test | total time to walk 10 meters | Baseline, Week 4, and Week 8 |
| 6 minute walk test | distance walked in 6 minutes | Baseline, Week 4, and Week 8 |

Inclusion Criteria:
Exclusion Criteria:
- No pregnant or lactating females (Potential female participants will be informed that risks to pregnant or lactating females are unknown; then they will be asked if they are pregnant or lactating, or if they could be pregnant. If there is any uncertainty, they will not be included in the study).

| Treadmill training | Behavioral | The goal of each session will be to increase balance and mobility challenge by increasing speed and minimizing BWS. Appropriate BWS will be chosen at the beginning of each training session. Participants will walk for 1 minute on the treadmill at 30%, 20% and 10% BWS. Maximum walking speed will be determined at each level of BWS and the participant will spend the remainder of the session ambulating with BWS at which they were able to achieve maximum walking speed. Additional BWS will be provided up to 30% of the participant's total body weight if the treating therapist identifies safety concerns or unfavorable gait kinematics. If a safe and kinematically appropriate gait pattern is unable to be achieved at up to 30% BWS, the previously determined walking speed will be reduced to achieve a safe and appropriate walking pattern. Participants will be encouraged not to use upper extremity support while ambulating with BWS. |
|
| Over ground training/standard of care | Behavioral | Standard of care interventions to address balance and mobility deficits will be chosen from a list of commonly used interventions in outpatient therapy. The goal of each session will be to increase balance and mobility challenge in an over ground condition focusing treatment in the following areas:
|
|
| Timed Up and Go | received verbal instructions to stand up from chair, walk 3 meters, cross a line marked on the floor, turn around, walk back and sit down | Baseline, Week 4, and Week 8 |
| Timed Up and Go Cognitive Test | receive verbal instructions to stand up from a chair, walk 3 meters, cross a line marked on the floor, turn around, walk back and sit down while counting backward by threes from a randomly selected number between 20 and 100 | Baseline, Week 4, and Week8 |
| Timed Up and Go Manual | receive verbal instructions to stand up from a chair, walk 3 meters as quickly and safely as possible, cross a lined marked on the floor, turn around, walk back and sit down while holding a cup filled with water | Baseline, Week 4, and Week 8 |
| Activities-Specific Confidence Scale | 16 item measure, scored from 0 to 100. Higher scores reflect great confidence of task | Baseline, Week 4, and Week 8 |
| CNS Vital Signs - Psychomotor Speed Domain | In-office neurocognitive test that is a non-invasive clinical procedure designed to efficiently and objectively assess a broad spectrum of brain function performance or domains under challenge. Finger tapping test and symbol digit coding will be aggregated to arrive at one reported value representing the psychomotor speed domain. Above average domain scores indicate a standard score (SS) greater than 109 or a Percentile Rank (PR) greater than 74, indicating a high functioning test subject. Average is a SS 90-109 or PR 25-74, indicating normal function. Low Average is a SS 80-89 or PR 9-24 indicating a slight deficit or impairment. Below Average is a SS 70-79 or PR 2-8, indicating a moderate level of deficit or impairment. Very Low is a SS less than 70 or a PR less than 2, indicating a deficit and impairment. | Baseline, Week 4, and Week 8 |
| CNS Vital Signs - Executive Functioning Domain | In-office neurocognitive test that is a non-invasive clinical procedure designed to efficiently and objectively assess a broad spectrum of brain function performance or domains under challenge. Shifting attention score will represent the executive functioning domain. Above average domain scores indicate a standard score (SS) greater than 109 or a Percentile Rank (PR) greater than 74, indicating a high functioning test subject. Average is a SS 90-109 or PR 25-74, indicating normal function. Low Average is a SS 80-89 or PR 9-24 indicating a slight deficit or impairment. Below Average is a SS 70-79 or PR 2-8, indicating a moderate level of deficit or impairment. Very Low is a SS less than 70 or a PR less than 2, indicating a deficit and impairment. | Baseline, Week 4, and Week 8 |
| CNS Vital Signs - Reaction Time Domain | In-office neurocognitive test that is a non-invasive clinical procedure designed to efficiently and objectively assess a broad spectrum of brain function performance or domains under challenge. Stroop test score will represent the reaction time domain. Above average domain scores indicate a standard score (SS) greater than 109 or a Percentile Rank (PR) greater than 74, indicating a high functioning test subject. Average is a SS 90-109 or PR 25-74, indicating normal function. Low Average is a SS 80-89 or PR 9-24 indicating a slight deficit or impairment. Below Average is a SS 70-79 or PR 2-8, indicating a moderate level of deficit or impairment. Very Low is a SS less than 70 or a PR less than 2, indicating a deficit and impairment. | Baseline, Week 4, and Week 8 |
| CNS Vital Signs - Cognitive Flexibility Domain | In-office neurocognitive test that is a non-invasive clinical procedure designed to efficiently and objectively assess a broad spectrum of brain function performance or domains under challenge. Shifting attention test and Stroop test scores will be aggregated to arrive at one reported value representing the cognitive flexibility domain. Above average domain scores indicate a standard score (SS) greater than 109 or a Percentile Rank (PR) greater than 74, indicating a high functioning test subject. Average is a SS 90-109 or PR 25-74, indicating normal function. Low Average is a SS 80-89 or PR 9-24 indicating a slight deficit or impairment.
