**5.4 Concussion balance test (COBALT)**

The Concussion Balance Test (COBALT), is an eight-condition test that assesses postural control with active vestibular stimulation using force plate technology (**Figure 4**). The test verifies the posture in a dynamic situation analogous to the one experienced during the sport. The goal is to try to reproduce the same or similar level of balance required to the activity. It is considered particular from other tools due the capability to identify subtle balance deficits. COBALT tasks the vestibular system by incorporating a head shake with an eyes-closed (visual suppression) [25].
