Touch localization
- Touch localization requires greater cortical interpretation of the sensory stimulus than touch awareness.
- Diminished touch localization may lead to decreased fine motor coordination. If the upper limb is involved, the patient may only be able to use it to assist with functional activities.
- It is normal for patients to respond more precisely in the hand than in the arm.
- If the patient lacks touch awareness, it is not necessary to test for touch localization or two-point discrimination.
