A bedside sensory phenomenon that can help explain functional sensory symptoms.

Explaining basic illness mechanisms is an important step in communicating functional neurological symptoms. Clinical signs for motor symptoms, such as the Hoover test, have proven an excellent basis for mechanistic explanations. Here, I recommend a simple technique for eliciting tingling sensations through directed bodily attention, as a helpful experiential starting point for explanations of sensory gating and somatosensory amplification in patients with functional hyperaesthesia, paraesthesia and chronic pain.
