Effects and feasibility of a standardised orientation and mobility training in using an identification cane for older adults with low vision: design of a randomised controlled trial

Abstract

BackgroundOrientation and mobility training (O&M-training) in using an identification cane, also called symbol cane, is provided to people with low vision to facilitate independent participation in the community. In The Netherlands this training is mainly practice-based because a standardised and validly evaluated O&M-training in using the identification cane is lacking. Recently a standardised O&M-training in using the identification cane was developed. This training consists of two face-to-face sessions and one telephone session during which, in addition to usual care, the client's needs regarding mobility are prioritised, and cognitive restructuring techniques, action planning and contracting are applied to facilitate the use of the cane. This paper presents the design of a randomised controlled trial aimed to evaluate this standardised O&M-training in using the identification cane in older adults with low vision.Methods/designA parallel group randomised controlled trial was designed to compare the standardised O&M-training with usual care, i.e. the O&M-training commonly provided by the mobility trainer. Community-dwelling older people who ask for support at a rehabilitation centre for people with visual impairment and who are likely to receive an O&M-training in using the identification cane are included in the trial (N = 190). The primary outcomes of the effect evaluation are ADL self care and visual functioning with respect to distance activities and mobility. Secondary outcomes include quality of life, feelings of anxiety, symptoms of depression, fear of falling, and falls history. Data for the effect evaluation are collected by means of telephone interviews at baseline, and at 5 and 17 weeks after the start of the O&M-training. In addition to an effect evaluation, a process evaluation to study the feasibility of the O&M-training is carried out.DiscussionThe screening procedure for eligible participants started in November 2007 and will continue until October 2009. Preliminary findings regarding the evaluation are expected in the course of 2010. If the standardised O&M-training is more effective than the current O&M-training or, in case of equal effectiveness, is considered more feasible, the training will be embedded in the Dutch national instruction for mobility trainers.Trial registrationClinicalTrials.gov NCT00946062

The impact of low vision on activities of daily living, symptoms of depression, feelings of anxiety and social support in community-living older adults seeking vision rehabilitation services

“…Details of the recruitment strategy were published elsewhere [20, 21]. The initial study sample consisted of 149 adults ≥55 years of age who lived independently or in a home for older people, applied for low-vision rehabilitation services (either by themselves or referred by other health care professionals) and were screened as potentially qualified for mobility training in the use of an identification cane.…”

Relative Difficulties of Daily Living Tasks with Retinitis Pigmentosa

“…27 The most effective 306 methods to teach the use of mobility aids, or orientation and mobility in general, are unclear with no 307 good quality evidence currently available. 27,28 There has been interest in determining whether a 308 standardised orientation and mobility teaching protocol would have better outcomes than usual 309 care, 29 but the results of the trial suggested little difference between techniques 30 although the trial 310 was hampered by trainers deviating from the standardised protocols, potentially to deliver more 311 client centred training. The subscales derived in the present study may be useful in informing the 312 development of training programmes, suggesting tasks that can be considered together in training 313 as forming a unidimensional construct from the client's perspective.…”

Cognitive–behavioural therapy-based intervention to reduce fear of falling in older people: therapy development and randomised controlled trial – the Strategies for Increasing Independence, Confidence and Energy (STRIDE) study

“…Numeric rating scales for pain and fear of falling when walking As summary measures of pain and fear of falling, participants were asked to rate these constructs on a 11-point scale, ranging from 0 (no concern/no pain) to 10 (as bad as it could be); a similar approach has been used in a number of studies as summarised by Scheffer et al The close relationship between fear of falling and falls 6,[8][9][10][11][12][13][14][15][16]23,24,26,27,29,58,59 means that measurements of falls and their adverse consequences are vital. Falls research is often hampered by poor definitions and hence difficult interpretation of falls outcome data.…”
