Abstract
ABSTRACT. Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease. In some cases, patients with ALS retain a normal level of consciousness but disease progression eventually results in generalized paralysis, which first impedes and then prevents oral communication. This communication obstacle can generate a great deal of stress for the patient, family, and caregiver. Here the authors ask whether the use of an eye-tracking assistive device can improve quality of life for ALS patients and relieves burden of their primary caregivers. Subjects were divided into two groups depending on whether they used (n = 10) or did not use (n = 10) an eye-tracking assistive device. The authors assessed patients’ quality of life and severity of depression using the ALS Specific Quality of Life Instrument–Revised and the Taiwanese Depression Questionnaire, respectively. The Caregiver Burden Scale was used to assess the burden on caregivers. Our study shows that the eye-tracking assistive device significantly improved patients’ quality of life, as compared with patients in the nonuser group (p <.01). The assistive device also reduced the burden on caregivers (p <.05). This is likely a result of the improvement of patient's autonomy and more effective communication between patient and caregiver.
