“…After pain, dizziness and unsteadiness are the next most frequent complaints in those with persistent problems following a whiplash trauma, with up to 70% reporting these complaints (Treleaven et al , 2003). These symptoms are thought to reflect a mismatch of afferent input from the proprioceptive, visual and or vestibular systems to the sensorimotor control system and have been associated with objective deficits in proprioception, head and eye movement control and balance in those with persistent whiplash (Sjöström et al , 2003, Treleaven et al, 2003, Treleaven et al , 2005b). Abnormal cervical afferent input, due to factors such as pain (Le Pera et al, 2001;Thunberg et al, 2001;Flor, 2003), altered neuromotor control (Falla, 2004), muscle fatigue, (Stapley et al 2006) and psychosocial stresses (Passatore and Roatta, 2006), is suggested be one of the main causes of these disturbances (Treleaven., 2008).…”
