Objective: The objective of this study was to evaluate the velocity of trunk extension movement, in three angular phases, within the range of 15 degrees per second (º/s) at 60º/s, in a person with double hemiparesis after traumatic brain injury. Methods: The sample consisted of a male participant, 18 years old, with predominant right hemiparesis, limitation of range of motion of the hip and right knee after TBI caused by automobile accident. The muscle strength of the trunk extensors was verified by isokinetic evaluation in a Cybex® model 6000 dynamometer. The isokinetic training program was performed twice a week, in 60-minute sessions, for 35 weeks. Results: After 10 sessions, the peak torque increase 193.0% and 160.0% in the concentric muscle strength of the trunk extensors performed at angular velocity of 15 and 30 degree per second respectively and, after 70 sessions, the improvement presented was 102% for angular velocity of 60 degree per second. Conclusion: Isokinetic training may contribute to the improvement of the muscular strength of the trunk extensors of a young adult with a neurological sequel after traumatic brain injury, and contributes to an improvement in balance, a decrease in pain and risk of future musculoskeletal injuries.
