The occupational therapist is frequently involved in the allocation process of lifting devices for clients with severe physical disabilities who are living in the community. The aim of this paper is to introduce a conceptual framework to help therapists prescribe lifting devices, including the slings. First, factors influencing the decision to prescribe such an aid are analysed based on the concepts of the Canadian Model of Occupational Performance (Canadian Association of Occupational Therapists, 1997). When working with clients toward maximizing their transfer skills, occupational therapists will take into account different aspects such as the characteristics of the client, the environment and the equipment, as well as the time allocated to complete the activity. Secondly, the notion of the work situation outlined by an organization specializing in work safety measures is used as a guide for transfer evaluation. From this viewpoint, the introduction of the lifting device occurs along a continuum of progressive loss of independence and is determined by degrees of personal independence, human assistance as well as technical assistance required to perform transfers. Finally, advantages and disadvantages of using lifting devices in a home setting are presented as a conclusion to the study.
