[Postural control disorders in initial phases of whiplash].

Background And Objective: Dizziness of variable intensity is a frequent complaint in patients who suffered whiplash and largely documented balance disturbances. The objective of the study was to identify balance disorders in early stage of whiplash after road traffic accidents.

Patients And Method: Ninety nine women were included in the study.

Angular position, range of motion and velocity of arm elevation: a study of consistency of performance.

Background: To define the normal range, velocity and consistency of the movement of active arm elevation with humerus in neutral or in external rotation using a simplified kinematic model.

Methods: Nine normal volunteers and the non-involved side of twenty five patients with unilateral shoulder lesion participated. A 3D optoelectronic tracking system was used to register the movement of raising the arm from the normal upright position to maximal elevation in a repetitive way.
