Table 1.
The table gives a brief rationale and description of specialized neglect interventions that have been used in combination and sequentially with other methods.
| Name of intervention | Procedure / rationale | Mechanism | Attentional load | Compensatory / restorative | Can be used simultaneously with |
|---|---|---|---|---|---|
| 1. CVS | Injection of cold water in the external ear canal produces correction of spatial coordinate frame | Bottom-up | Passive | Restorative | 2-10 |
| 2. EP & RHB | Eye patches are worn to produce Sprague effect (visually-guided behavior to the contralateral space) | Bottom-up | Passive | Restorative | 1, 3-10 |
| 3. LAT | Active and passive movements with a left limb to the left to increase the function of the right hemisphere | Bottom-up | Active / Passive | Compensatory | 1-2,4-10 |
| 4.NV | Vibration applied to posterior part of left neck muscles to recalibrate egocentric/spatial coordinates | Bottom-up | Passive | Restorative | 1-3, 5-10 |
| 5. OPKS | Leftward moving background of a screen that causes recalibration of spatial coordinates | Bottom-up | Active | Restorative | 1-4, 9 |
| 6. PA | Successive pointing movements while wearing prisms that produces visuo-motor adaptation | Bottom-up | Active | Restorative | 1-4, 9 |
| 7. SAT | Examiner touches different locations on a patients back and the patient has to indicate the touched location on a mannequin in front of them | Top-down | Active | Compensatory | 1-4, 9 |
| 8. SATG | Sequential sound stimulation to alert spatial attention to left | Top-down | Active | Compensatory | 1-2, 9 |
| 9. TENS | Surface stimulation with electrical impulses that generate tingling sensation | Bottom-up | Passive | Compensatory | 1-8, 10 |
| 10. VST | Uncued and cued voluntary scanning eye movement training to the left side of a scanning board | Top-down | Active | Compensatory | 1-3, 9 |
