Intensive Physical Exercise Versus Standard Exercise During Rehabilitation of Patients With Traumatic Brain Injury

2-week training program with daily sit-to-stand exercises. Each working day the participant's goals will be adjusted, until exercising a minimum of 100 repetitions using an exercise progression table. When participants complete one level, they will progress to the next level the following day. Participants who do not reach the goals at level one will continue to strive to reach the 100 repetitions. The number of repetitions can be split and performed throughout the day. As the participants' capacity for doing the exercises increases, so will the number of repetitions within each bout of sit-to-stand. Participants are allowed to do the number of repetitions from a higher exercise level if they can and will continue by progressing from that level on the next day. The repetitions will be done from a height that makes it possible to accomplish the sit-to-stand movement. Therefore, the height of the sitting surface will be adjusted according to the participant's abilities.
