Somatosensory function refers to the detection, discrimination and recognition of body (somato) sensations. Somatosensations include submodalities of touch sensation such as light touch (on the surface of the skin), firm pressure and texture discrimination, proprioception involving sensing the location and movement of body parts, temperature sensation, pain (nociception) and itch. These sensations arise from sensory receptors in the skin, joints, tendons, muscles and viscera. For Toolbox, the term ‘somatosensation’ will refer to all aspects of touch and proprioception that contribute to a person’s awareness of their body parts and the direct interface of these with objects and the environment. The experience of sensing often involves a more complex integration of somatosensory inputs (e.g. haptic recognition of objects) or somatosensory and emotional components (e.g., pain) and may be influenced by emotional and social contexts (e.g. perception of tickle).
