Postural instability is a typical characteristic of individuals with PD, which increases the frequency of falls and may worsen their consequences. It thus seems relevant to diagnose these alterations as early as possible, in order to develop specific rehabilitative treatment. The association between sensitivity of the sole of the foot and postural instability in individuals with PD is linked to the key role of peripheral alterations of the sensorimotor system in balance and motor symptoms. By enhancing sensory feedback coming from the feet, bottom-up stimulation allows patients to improve their sensorimotor control. In clinical practice, health practitioners can use sensory stimulation to improve postural control. By improving postural stability, a decrease in fall risk can be achieved and the secondary impairments associated with falls prevented.We report on a 7-year-old female who presented paroxysmal episodes of loss of consciousness with clonic movements. The electroencephalogram (EEG) evidenced diffuse slow wave activations, with no symptoms. Epilepsy was suspected but antiepileptic drugs were ineffective. Video-EEG monitoring revealed that the syncope was triggered by stretching with a tachycardia that started during the stretch maneuver and diffuse slow waves on the EEG 2s before the symptoms. Stretch syncope can result in striking manifestations with subcortically driven clonic movements that can be mistaken for signs of epilepsy. Stretching might lead to transient hypoxia of the brainstem; in turn, this might activate the thalamocortical loop and thus generate cardiovascular changes, EEG slow waves, and physical man
