New research indicates that a small amount of bed rest is appropriate over the first 48 to 72 hours after a mild traumatic brain injury or concussion. The newest recommendations are to limit bedrest to no more than three days and encourage a gradual return to normal activities, as long as there are no obvious continued symptoms such as headaches, dizziness, nausea, poor balance or visual disturbances. Close monitoring for symptoms during the recovery period is critical.
