It will require a light touch and a high level of awareness of the qualities of surfaces, materials and light.
Loss of sensation to light touch bilaterally at the dermatomal level of T5 or above is the most reliable method to ensure satisfactory surgical anesthesia.
Two-point discrimination, thermal sensation, and light touch sensation at the gingival level show no significant difference between test and control groups (Table 1) [ 14, 16, 26, 28].
A neurologist undertook an examination, independently of ASIA examination, that included history, pin prick, motor assessment and assessment of light touch and pin prick impairment level measured from the sternal notch anteriorly and the spinous process posteriorly.
On neurological exam, sensation was intact to light touch above approximately the T5 sensory level, and numbness was present below the T5 sensory level bilaterally.
Sensory exam was significantly abnormal; pinprick and light touch sensations were impaired up to level of mid-calf bilaterally, there was moderate deficit of joint position sensation at the toes.
Additionally, light touch sense was related to the anatomical level below which it was impaired: no abnormalities (0), toe (1), mid-foot (2), ankle (3), mid-calf (4) and knee (5).
You have to use a pretty light touch and try to keep the edge level so that one end doesn't dip into the drywall.
After an additional three minutes, testing for sensory level was again performed with an alcohol swab and light touch.
After five minutes, testing for sensory level was performed with an alcohol swab (for temperature) and light touch.
