Shoulder Biomechanics During the Push Phase of Wheelchair Propulsion: A Multisite Study of Persons With Paraplegia

摘要: Abstract Collinger JL, Boninger ML, Koontz AM, Price R, Sisto SA, Tolerico Cooper RA. Shoulder biomechanics during the push phase of wheelchair propulsion: a multisite study persons with paraplegia. Objectives To present descriptive analysis and comparison shoulder kinetics kinematics propulsion at multiple speeds (self-selected steady-state target speeds) for large group manual users paraplegia while also investigating effect pain subject demographics on propulsion. Design Case series. Setting Three laboratories research institutions. Participants Volunteer sample 61 who use mobility. Intervention Subjects propelled their own wheelchairs dynamometer 3 (self-selected, 0.9m/s, 1.8m/s) kinetic kinematic data were recorded. Main Outcome Measures Differences in between sites, correlations characteristics, without pain, linear regression using characteristics to predict biomechanics, speed conditions. Results Significant increases joint loading increased velocity observed. Resultant force from 54.4±13.5N 0.9m/s trial 75.7±20.7N 1.8m/s ( P Conclusions Body-weight maintenance, as well other interventions designed reduce required propel wheelchair, should be implemented prevalence injury among users.
