Clinical Trial Summary

The project will consist of subjects who have suffered Traumatic Brain Injury (TBI) and who are able to ambulate on treadmill with or without a harness system. This will be a 4-week controlled study consisting of two groups of TBI patients, high-intensity intervention group and low-intensity control group. Both groups will receive physical therapy treatment 3 times per week for 1 hour. The intervention group will undergo 30-minute sessions of high-intensity walking on a treadmill with an overhead harness attached for safety. In addition, they will also get up to 30-minutes of low-intensity physical therapy in order to receive 1 hour of treatment time. The control group will undergo only low-intensity physical therapy activities for 1-hour. Low-intensity physical therapy will include strength exercises, stretches, balance, and low-intensity gait training. All participants in both groups will complete these outcome measures on the first day of the study, after 2 weeks of participation, and again at the end of 4 weeks or on their last day before discharge from Carilion's services. Later on, all participants in both groups will be followed up to complete the same set of outcome measures at the end of 1 month since completion of the protocol. This follow up session will take up to 45 minutes to complete.


Description:

Gait, mobility and cognitive function will be first assessed using seven standardized performance-based outcome measures including both mobility and cognitive measures. All participants in both groups will complete these outcome measures on the first day of the study, after 2 weeks of participation, again at the end of 4 weeks, or on their last day before being discharged from Carilion's services, and 1 month after their 4 week completion. Participants of the intervention group will undergo physical therapy for 3 days a week for 4 weeks, with each session lasting a total of 60 minutes. They will start with 30 minutes of high-intensity gait training (HIGT) followed by up to 30 minutes of low-intensity therapy. For HIGT, participants will be secured safely on a treadmill with or without an overhead harness and unweighting system for successful gait training. Their resting HR and BP would be noted. Participants would begin with a warmup for 3 minutes by walking at low speeds with intensity of 30-50% of heart rate reserve (HRR). HR would be monitored continuously from here onwards till the conclusion of the protocol. Following the warmup, treadmill walking speed will be initially set at target HR of 85%HRR that was noted from the treadmill test. If the participant did not reach 85% HRR during the treadmill test, treadmill speed would be set by subtracting 0.1 mph (or 0.1 treadmill workload unit) from the speed at which they started showing gait instability or backward drift during the treadmill test. The goal would be to have participants walk at high aerobic intensity with target HR between 60-85%HRR, ideally close to 85%HRR, for 25 minutes. The studies report that the closer the heart rate can be maintained to the 85% target HR, the more beneficial the training. If a participant is unable to achieve at least 60%HRR in the first few minutes of high-intensity phase, the participant's feeling of physical exertion would also be measured by asking them about a score on the Rates of Perceived Exertion (RPE) scale of 0-10. Here the goal would be to have them maintain an exertion intensity score of 5-8. If needed, participants would be allowed to rest by standing or sitting down. The amount of time spent in high-intensity and rest periods would be recorded. BP will also be recorded at 15-minute and 25-minute timepoints, or during rest breaks. At conclusion of 25 minutes of HIGT, participants will cool down for 2 minutes by walking at 30-50% HRR. Their HR and BP will again be measured at the end of the cool down period. Besides HR and BP, participant's oxygen saturation would also be monitored during this protocol using a pulse oximeter to assess blood oxygen levels. Depending on the remaining time and activity tolerance levels, intervention group participants will then perform up to 30 minutes of low-intensity physical therapy until they have reached a total of 60 minutes for that session. These may consist of low-intensity gait activities, exercises (such as lower extremity strength training with or without weights or electrical stimulation, sit to stands from a chair, mat exercises for upper/lower extremities and core strength, etc.), stretches, balance, and other therapeutic activities (such as transfers, bed mobility training, etc.) for functional mobility. Participants in the control group will receive 60-minute sessions of only low-intensity physical therapy for 3 days a week for 4 weeks. Here, the goal is to have the participants work at a lower intensity with a target HR below 60%HRR. Low-intensity physical therapy could include low-intensity gait activities, exercises (such as lower extremity strength training with or without weights or electrical stimulation, sit to stands from a chair, mat exercises for upper/lower extremities and core strength, etc.), stretches, balance, and other therapeutic activities (such as transfers, bed mobility training, etc.). During these sessions, HR and BP would be measured and noted at regular intervals to monitor and note the cardiorespiratory intensity of those activities.
