BACKGROUND: Usual guidelines recommend symmetric load carriage over asymmetric load carriage. Whether this recommendation is valid for subjects with asymmetric body alignment, such as those with scoliosis, remains unclear. Scoliosis is both a subject-dependent and time-variant condition. Interventions are generally employed to prevent the abnormal spinal curvature from progressing. OBJECTIVES: To investigate the effects of an asymmetric load carriage on lateral spinal deformity in participant with scoliosis...

BACKGROUND: Shared decision making is a consultative process designed to encourage patient participation in decision making by providing accurate information about the treatment options and supporting deliberation with the clinicians about treatment options. The process can be supported by resources such as decision aids and discussion guides designed to inform and facilitate often difficult conversations. As this process increases in use, there is opportunity to raise awareness of shared decision making and the international standards used to guide the development of quality resources for use in areas of prosthetic/orthotic care...

BACKGROUND: In 1970, Mori hypothesised the existence of an 'uncanny valley', whereby stimuli falling short of being fully human are found to be creepy or eerie. OBJECTIVES: To investigate how eerie people find different prosthetic hands and whether perceptions of eeriness can be accounted for by categorical ambiguity. STUDY DESIGN: Students participated in computerised experiments during which photographic images of hands were presented. METHODS: We compared photographs of prosthetic hands pre-selected as more (H+) or less human-like (H-), as well as mechanical and real hands...

BACKGROUND AND AIM: Patient-reported outcome measures are increasingly used to evaluate effectiveness of treatment. However, the use of 'paper and pencil' questionnaires is time-consuming for both patients and healthcare specialists. Therefore, the aim of this project was to develop a custom-built web-based monitoring system. TECHNIQUE: We incorporated reliable and valid questionnaires on all domains of human functioning as described in the World Health Organization's Classification of Functioning, Disability and Health (ICF and ICF-CY)...

BACKGROUND: The evolution of three-dimensional printing into prosthetics has opened conversations about the availability and cost of prostheses. This report will discuss how a prosthetic team incorporated additive manufacture techniques into the treatment of a patient with a partial hand amputation to create and test a unique assistive device which he could use to hold his French horn. Case description and methods: Using a process of shape capture, photogrammetry, computer-aided design and finite element analysis, a suitable assistive device was designed and tested...

BACKGROUND: Active individuals with transfemoral amputations are provided a microprocessor-controlled knee with the belief that the prosthesis reduces their risk of falling. However, these prostheses are expensive and the cost-effectiveness is unknown with regard to falls in the transfemoral amputation population. The direct medical costs of falls in adults with transfemoral amputations need to be determined in order to assess the incremental costs and benefits of microprocessor-controlled prosthetic knees...

BACKGROUND: In all, 68% of all lower limb amputees experience residual limb pain. More than 95% of all lower limb amputations in developed countries are due to peripheral artery occlusive disease in combination with diabetes mellitus. Therefore, claudication, which is one of the most common manifestations of peripheral artery occlusive disease, should be taken into consideration in making a differential diagnosis of residual limb pain. Case description and methods: We present a case study of a 60-year-old diabetic patient who underwent a transfemoral amputation due to peripheral artery occlusive disease and who experiences residual limb pain...
