Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is a "proof-of-principle" project to examine the safety and feasibility of implementing a 1-week aerobic exercise program in the post-acute phase after mild traumatic brain injury (mTBI). The study will define the extent to which the exercise program improves recovery from mTBI in terms of relevant functional outcomes (cognition, mood, and physical status) and biomarkers (peripheral brain-derived neurotrophic factor \[BDNF\] concentration).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a "proof-of-principle" project for human subjects to examine the safety and feasibility of implementing a 1-week aerobic exercise program in the post-acute phase after mild traumatic brain injury (mTBI). This study will define the extent to which the exercise program improves recovery from mTBI in terms of relevant functional outcomes (cognition, mood, and physical status) and biomarkers (peripheral brain-derived neurotrophic factor \[BDNF\] concentration). This project will also lay the foundation for understanding the relationship between exercise and BDNF in the area of mTBI neurorecovery, thereby allowing future studies to develop best-practice methods for implementing exercise interventions as a treatment option for brain injuries.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

mTBI Aerobic Exercise Group

Participants are two-three weeks post-mild traumatic brain injury are randomized to receive a daily aerobic exercise intervention lasting 1-week.

Group Type EXPERIMENTAL

Aerobic Exercise

Intervention Type BEHAVIORAL

Aerobic exercise will consist of riding a stationary bicycle at moderate intensity for 2 consecutive, 20-minute periods with a 5-minute break in between. Moderate intensity is defined as maintaining 65-75% of estimated maximum heart rate based on the calculation (HRmax = 208 - 0.7 × age).

mTBI Non-Aerobic Exercise Group

Participants are two-three weeks post-mild traumatic brain injury are randomized to receive a daily non-aerobic exercise intervention lasting 1-week.

Group Type EXPERIMENTAL

Non-Aerobic Exercise

Intervention Type BEHAVIORAL

Non-Aerobic exercise will consist of very low-intensity movements including static stretching and toning exercises.Participants will complete 2 consecutive, 20-minute periods with a 5-minute break in between, mirroring the aerobic exercise condition. Heart rate will be monitored by research staff to ensure that it remains below 50% of estimated maximum heart rate.

Non-injured Reference Group

Non-injured, healthy participants will serve as a reference group for functional outcome measures.

Group Type NO_INTERVENTION
