This impairment of body perception involves vision, proprioception, and tactile perception. During this phase the patient will complete advanced balance, proprioception, cardiovascular conditioning, and neuromuscular interventions. Goals of therapy are to improve tactile sensation, proprioception, and range of motion. Experimenters typically manipulate stimuli affecting vision, hearing, touch, smell, taste and proprioception. The specific mechanics of proprioception in the temporomandibular joint involve four receptors. Good levels of physical strength, flexibility, and proprioception should be achieved before beginning plyometric training. There is a four-neuron pathway for lower limb proprioception. The posterior thoracic nucleus is a major relay center for unconscious proprioception. Bodily-awareness also includes proprioception and sensation. Damage to the cerebral peduncles results in unrefined motor skills, imbalance, and lack of proprioception. The senses of touch and proprioception of the left side were impaired. The proprioception of the lower limbs differs from the upper limbs and upper trunk. Both proprioception and interoception allow individuals to be consciously aware of various sensations. A conscious proprioception is achieved through increased awareness. Human teeth have a blood and nerve supply which enables proprioception.
