Rehabilitation services for these populations are highly in demand since traditional uni\u2010sensory rehabilitation approaches using the other sense to compensate are not always utilizable. Very little is currently known about the client population characteristics with dual sensory impairment. The present study provides information about demographic and sensory variables of persons in the Montreal region that were receiving rehabilitation for dual impairment in December 2010. This information can inform researchers, clinicians, educators, as well as administrators about potential research and service delivery priorities.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Method:\u2002<\/jats:bold>\n                      A chart review of all client files across the three rehabilitation agencies that offer integrated dual sensory rehabilitation services in Montreal provided data on visual acuity, visual field, hearing detection thresholds, and demographic variables.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Results:\u2002<\/jats:bold>\n                      The 209 males and 355 females ranged in age from 4\u2003months to 105\u2003years (\n                      <jats:italic>M\u2003<\/jats:italic>\n                      =\n                      <jats:italic>\u2003<\/jats:italic>\n                      71.9, S.D.\u2003=\u200324.6), indicating a prevalence estimate for dual sensory impairment at 15\/100\u2003000. Only 5.7% were under 18\u2003years of age, while 69.1% were over the age of 65\u2003years, with 43.1% over the age of 85\u2003years. The diagnostic combination that accounted for 31% of the entire sample was age\u2010related macular degeneration with presbycusis. Their visual and auditory measures indicated that older adults were likely to fall into moderate to severe levels of impairment on both measures. Individuals with Usher Syndrome comprised 20.9% (\n                      <jats:italic>n<\/jats:italic>\n                      \u2003=\u2003118) of the sample.\n                    <\/jats:p>\n                    <jats:p>\n                      <jats:bold>Conclusion:\u2002<\/jats:bold>\n                      The age distribution in this sample of persons with dual sensory impairment indicates that service delivery planning will need to strongly consider the growing presence of older adults as the baby\u2010boomers approach retirement age. The distribution of their visual and auditory limits indicates that the large majority of this client group has residual vision and hearing that can be maximized in the rehabilitation process in order to restore functional abilities and social participation. Future research in this area should identify the specific priorities in both rehabilitation and research in individuals affected with combined vision and hearing loss.\n
