Transcript

  • 1. 1<br />Assessment and Training for people with Neurological Vision Deficits<br />NVT: Developed by Clinicians, for Clinicians<br />
  • 2. Acquired Brain Injury<br /><ul><li>Acquired Brain Injury (ABI) is damage to the brain by a variety of causes; hypoxia, infection, tumour, substance abuse, degenerative neurological diseases, strokes or head trauma (TBI).
  • 3. Traumatic Brain Injury (TBI) implies trauma to the head and brain caused by an external force.
  • 4. ABI can cause physical, cognitive, psychosocial and sensory impairments which may lead to restrictions in various areas of a person’s life and lifestyle. </li></li></ul><li>2.2 Million People in the US Acquired Brain Injury<br />Every Year<br />1.5 million Traumatic Brain Injury: every 21 seconds<br />700,000 will have a Stroke: one every 45 seconds<br />Stroke is the number 3 killer and leading cause of severe, long-term disability<br />
  • 5. 4<br /> Neurological Vision Impairment<br /><ul><li>Neurological Vision Impairment occurs in 30 – 35% of all people who suffer a </li></ul>Stroke or Traumatic Brain Injury.<br />“50% of the patients in a head trauma rehabilitation centre show visual system disorders not assessed before, although most of the patients were chronic and had been treated in other hospitals previously.” (Gianutsos)<br />
  • 6. Neurological Vision Deficits<br />
  • 7. 6<br />Vision Therapy<br /><ul><li>Neurological Vision Impairment will affect all aspects of a persons daily life.
  • 8. It would be standard care to receive:
  • 9. Physiotherapy– for improvement in loss of body functions or reduced movement.
  • 10. Occupational Therapy – to increase upper body strength and activities of daily living.
  • 11. Speech Therapy - swallowing, word pronunciation, comprehension etc
  • 12. In many instances there is no minimum clinical standard of care that covers Vision Screening for people with ABI
  • 13. Therefore vision deficits can go undiagnosed and untreated.</li></li></ul><li>7<br />Assessment of Visual Function<br />
  • 14. 8<br />NVT Protocol Functional Vision Assessment<br />
  • 15. 9<br />Visual Perceptual Deficits<br />Homonymous Hemianopiais the most common cause of visual field loss, quadrantanopia, relative field loss.<br /><ul><li>Visual Neglect/Visual Inattention - patients can be unaware of the extent of vision loss – causes difficulty with ALL activities of daily living (reading, eating, dressing, mobility in busy or unfamiliar areas).
  • 16. Visual processing speed
  • 17. Visual Memory
  • 18. Visual Spatial deficits</li></li></ul><li>10<br />NVT Standardized Scanning Assessment<br />
  • 19. 11<br />Case Study - Angela<br /><ul><li>Motor Vehicle Accident TBI:
  • 20. Damage to:</li></ul>frontal lobe, <br />bi-temporal, <br />bi-parietal and <br />occipital craniotomy<br /><ul><li>Left Homonymous </li></ul>Quadrantanopia<br /><ul><li>Left Neglect
  • 21. Visuo-spatial deficits
  • 22. Visual processing deficits
  • 23. Left Hemiparesis & Balance
  • 24. Memory</li></li></ul><li>12<br /> Static Scanning Sitting Standing<br />
  • 25. 13<br />Pen and Paper Tasks<br />Transfer of scanning skills to table top tasks.<br />Systematic scanning pattern<br />Smooth scanning across a line in<br /> preparation for reading<br />
  • 26. 14<br />Transfer to Walking and Scanning<br />Step by step methodology in the transfer of scanning skills to mobility tasks in a graded fashion in a client’s local community.<br />
  • 27. 15<br />Progression - Scanning Skills Outdoors<br />
  • 28. 16<br />Supermarket<br />Shopping<br />Transferring scanning skills into<br />everyday community settings.<br />Preparation for independent living.<br />
  • 29. 17<br />Street <br />Crossings,<br />Car Parks<br />Transfer from walking frame<br />to support cane.<br />Ensuring balance, gait and <br />Scanning skills are not <br />compromised.<br />
  • 30. 18<br />Residential Area - Driveways<br />Transfer of scanning <br />skills into residential <br />settings. <br />Scanning into driveways<br /> for potential hazards<br />Good head turn,<br />chin over shoulder for self monitoring<br />
  • 31. 19<br />The NVT Vision Rehabilitation System<br />NVT Scanning Device - Standardised Assessment and Treatment protocols<br />2. Vision 2000 Software - rehabilitation and patient management system<br />3. Comprehensive Training program for rehabilitation therapists.<br />
