Patients with amyotrophic lateral sclerosis (ALS) rely on a variety of support services during the course of their illness. Patients with primary lateral sclerosis (PLS) have a slower progression of disease and different clinical spectrum. Their needs for allied health services and social support have not been well characterized. To investigate these needs, 25 patients with PLS and caregivers were surveyed on the use of assistive devices and support services. Needs for assistance changed as the disease progressed. Their greatest need was for gait-assistive devices and home help for activities requiring mobility. As in other chronic diseases, there was a striking use of the internet to gather information and for patient support groups.
