An observational study of trait and state fatigue, and their relation to cognitive fatigability and saccade performance.

Aim: Different fatigue measurements and their relation to saccadic functions were investigated in 15 patients with a mild traumatic brain injury (mTBI) and 15 orthopedic controls.

Materials & Methods: State fatigue was measured with the Fatigue Severity Scale and trait fatigue with the question on fatigue in the Rivermead Post Concussion Questionnaire and fatigability as decreased performance over time on a neuropsychological measure.

Results: Patients with an mTBI scored significantly higher in state fatigue and showed more fatigability compared with the orthopedic controls.

Longitudinal changes in oculomotor function in young adults with mild traumatic brain injury in Sweden: an exploratory prospective observational study.

Objectives: To assess (1) whether visual disturbances can be demonstrated with objective measures more often in patients with mild traumatic brain injury (mTBI) than in orthopaedic controls and non-injured controls, (2) whether such objectively demonstrated disturbances change over time and (3) whether self-reported visual symptoms after mTBI correlate with objectively measurable changes in visuomotor performance.

Design: A prospective, controlled, observational study, with assessments planned 7-10 and 75-100 days after injury.

Setting: Emergency department of a general hospital in Sweden.

No effect of an early intervention after mild traumatic brain injury on activity and participation: A randomized controlled trial.

Objective: To evaluate measures of activity, participation and quality of life 3 months after mild traumatic brain injury and the effect of an early intervention for patients with an estimated high risk for problems after mild traumatic brain injury.

Patients: Consecutive patients attending the emergency room with mild traumatic brain injury.

Design: Randomized controlled trial.

Early intervention for patients at risk for persisting disability after mild traumatic brain injury: a randomized, controlled study.

Study Objective: To investigate the effect of an early intervention visit in addition to written information and treatment as usual for patients with an estimated high risk for persisting disability after a mild traumatic brain injury (MTBI).

Research Design: Randomized controlled trial.

Methods: One hundred and seventy-three patients, aged 15-70 years with a Glasgow coma scale of 14-15 were included.
