Comparison of Two Lighting Assessment Methods when Reading with Low Vision.

Significance: Lighting assessments are an important component of low-vision rehabilitation but are rarely studied systematically. Our study indicates that preferred lighting levels support improvements in reading ease and enjoyment, independently of the evaluation technique. To determine preferred illumination level and color temperature, the LuxIQ is quicker to administer and covers broad options of settings.

The challenge of reading music notation for pianists with low vision: An exploratory qualitative study using a head-mounted display.

Reading musical notation while interpreting it on a musical instrument poses problems for musicians with a visual impairment (VI). This study sought to describe the visual aids, adaptations and compensatory strategies used by five amateur pianists with low vision when reading music, to identify the problems they face when using these aids, and to verify whether a head-mounted display (HMD) such as eSight Eyewear can be used to overcome some of them. In this exploratory study, the participants read and interpreted two excerpts of musical notation using eSight Eyewear.

Charles Bonnet syndrome: development and validation of a screening and multidimensional descriptive questionnaire.

Objective: The purpose of this study was to develop a French Canadian questionnaire for the detection of Charles Bonnet syndrome that allows for (i) valid screening and (ii) the examination of different dimensions of the client's visual hallucinations in order to better assess the resulting needs.

Method: Questionnaire development was guided by interviews with visually impaired individuals experiencing visual hallucinations, as well as supported by scientific literature and expert experience. A clinical study involving 76 individuals with low vision was conducted to determine the sensitivity and specificity of the instrument according to criterion validation.

Reliability and validity of the Canadian-French ecological adaptation of the weighted version of the Melbourne low-vision ADL Index.

The (MIDVAQ) is the Canadian-French adaptation of the Melbourne Low-Vision ADL Index. It measures performance, personal importance and handicap situation in 16 instrumental activities requiring near vision (standardized material, part A) and in 9 self-care and domestic activities (self-report questionnaire, part B). This study aimed at measuring the MIDVAQ reliability and its relationship with measures of visual functions and functional vision.

Impact of partial administration of the Cognitive Behavioral Driver's Inventory on concurrent validity for people with brain injury.

Objectives: We sought to determine whether the partial administration of the Cognitive Behavioral Driver's Inventory (CBDI) has a significant effect on its concurrent validity.

Method: Data were extracted from charts of clients with cerebrovascular accident or traumatic brain injury from three centers. The CBDI was administered either completely or partially (right and left perimetry or Wechsler Adult Intelligence Scale-Revised (WAIS-R; Wechsler, 1982; Picture Completion and Digit Symbol tests were not completed).

Test-retest reliability and internal consistency of the Quebec-French version of the Survey of Pain Attitudes.

Objective: To determine the test-retest reliability and internal consistency of the Quebec-French version of the Survey of Pain Attitudes (QAD/F-SOPA).

Design: Measurement of test-retest reliability (2-wk interval) and internal consistency.

Setting: Five rehabilitation settings that offer services to chronic pain patients.
