ICF Core Sets for osteoporosis.

OBJECTIVE: To report on the results of the consensus process integrating evidence from preliminary studies to develop the first version of a Comprehensive International Classification of Functioning, Disability and Health (ICF) Core Set and a Brief ICF Core Set for osteoporosis. METHODS: A formal decision-making and consensus process integrating evidence gathered from preliminary studies was followed. Preliminary studies included a Delphi exercise, a systematic review, and an empirical data collection. After training in the ICF and based on these preliminary studies, relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preliminary studies identified a set of 239 ICF categories at the second, third and fourth ICF levels with 72 categories on body functions, 41 on body structures, 81 on activities and participation, and 45 on environmental factors. Fifteen experts from 7 different countries attended the consensus conference on osteoporosis. Altogether 67 second-level and 2 third-level categories were included in the Comprehensive ICF Core Set with 15 categories from the component body functions, 7 from body structures, 21 from activities and participation, and 26 from environmental factors. The Brief ICF Core Set included a total of 22 second-level categories with 5 on body functions, 4 on body structures, 6 on activities and participation, and 7 on environmental factors. CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF framework and classification led to the definition of ICF Core Sets for osteoporosis. Both the Comprehensive ICF Core Set and the Brief ICF Core Set were defined.

ICF Core Sets for chronic widespread pain.

OBJECTIVE: To report on the results of the consensus process integrating evidence from preliminary studies to develop the first version of a Comprehensive ICF Core Set and a Brief ICF Core Set for chronic widespread pain. METHODS: A formal decision-making and consensus process integrating evidence gathered from preliminary studies was followed. Preliminary studies included a Delphi exercise, a systematic review and an empirical data collection. After training in the ICF and based on these preliminary studies relevant ICF categories were identified in a formal consensus process by international experts from different backgrounds. RESULTS: The preliminary studies identified a set of 365 ICF categories at the second, third and fourth ICF levels with 143 categories on body functions, 45 on body structures, 125 on activities and participation and 125 on environmental factors. Thirty experts attended the consensus conference on chronic widespread pain (16 physicians with at least a specialization in physical and rehabilitation medicine, 4 rheumatologists, 2 psychiatrists, 5 physical therapists, one psychologist, one occupational therapist and 1 social worker). Altogether 65 second-level and 2 third-level categories were included in the Comprehensive ICF Core Set with 23 categories from the component body functions, one from body structures, 27 from activities and participation and 16 from environmental factors. The Brief ICF Core Set included a total of 24 second-level categories and 2 third-level categories with 10 on body functions, 10 on activities and participation and 6 on environmental factors. No body structures were included in the Brief ICF Core Set. CONCLUSION: A formal consensus process integrating evidence and expert opinion based on the ICF framework and classification led to the definition of ICF Core Sets for chronic widespread pain. Both the Comprehensive ICF Core Set and the Brief ICF Core Set were defined.

Wheelchair coasting downhill is a reliable work task.

OBJECTIVE: To measure test-retest reliability of physiological responses during submaximal wheelchair downhill and horizontal treadmill ergometry. DESIGN: A test-retest design was used on a convenience sample. Four male and three female non-wheelchair users, (22-43 years of age) propelled or coasted in a wheelchair under steady-state conditions. Four minute work bouts were performed at 1, 2, 3, and 4 km/hr. (0.62, 1.24, 1.86 and 2.5 mph, respectively) at 0 degrees, -2 degrees, and -4 degrees. Subjects were studied twice under each of the 12 conditions. Six tests were performed daily, with testing occurring over four days. Dependent variables included oxygen consumption, minute ventilation and heart. Intraclass correlation coefficients were determined for each set of paired tests. RESULTS: Intraclass correlation coefficients were high for absolute VO_{2}(R=0.84-0.99), V_{E} (R=0.86-0.98) and HR (R=0.95-1.0) over the range of 4 speeds and 3 inclinations studied. On average, % differences from test 1 to test 2 were less than 3%. CONCLUSION: At the treadmill speeds and inclinations (positive and negative) studied in this investigation, untrained wheelchair users responded in a physiologically reliable manner.

Computerized manufacturing of transparent face masks for the treatment of facial scarring.

In this work an integrated system of computer-aided design and computer-aided manufacturing specifically designed to fabricate affordable transparent face masks is discussed. FaceScan, a custom-designed software system, integrates shape capture, mask design, and pattern fabrication. The software controls a linear scan noncontact laser imager for facial topography acquisition and a milling machine for pattern fabrication. Compared with conventional methods of mask fabrication, this system is faster, more accurate, and less stressful for the patient and allows for greater control of the finished product. Masks for two subjects have been successfully fabricated using this system.
