40 patients with hip osteoarthritis undergoing total hip replacement were included in this trial to determine the effectiveness of occupation therapy supervised usage of adaptive devices. Patients were randomized to an experimental group that used adaptive devices in an organized and supervised manner or to a control group that used devices without supervision. Devices included abduction pillows, elevated toilet seats, reachers, and cushion seats. The purpose of this study was to determine whether supervision from an occupational therapist improved pain and disability outcomes, as well as hip muscle strength while using these adaptive devices. Outcomes were assessed up to 6 weeks postoperatively. Findings indicated significantly more favourable outcomes with supervised use of adaptive devices compared to unsupervised use in all pain, disability, independence, and hip muscle strength variables.
