Technology-Aided Programs to Support Positive Verbal and Physical Engagement in Persons with Moderate or Severe Alzheimer’s Disease
OBJECTIVE Assessing automatic feedback technologies to promote safe travel and speech loudness control in two men with multiple disabilities, respectively. METHOD The men were involved in two single-case studies. In Study I, the technology involved a microprocessor, two photocells, and a verbal feedback device. The man received verbal alerting/feedback when the photocells spotted an obstacle in front of him. In Study II, the technology involved a sound-detecting unit connected to a throat and an airborne microphone, and to a vibration device. Vibration occurred when the man's speech loudness exceeded a preset level. RESULTS The man included in Study I succeeded in using the automatic feedback in substitution of caregivers' alerting/feedback for safe travel. The man of Study II used the automatic feedback to successfully reduce his speech loudness. CONCLUSION Automatic feedback can be highly effective in helping persons with multiple disabilities improve their travel and speech performance.
