UNLABELLED Wheelchair propulsion plays a significant role in the development of shoulder pain in manual wheelchair users (MWU). However wheelchair propulsion metrics related to shoulder pain are not clearly understood. This investigation examined intra-individual kinematic spatial variability during semi-circular wheelchair propulsion as a function of shoulder pain in MWU. Data from 10 experien...

The hydrodynamics of the waterjet-propelled ship is a challenging issue due to sophistication waterjet system geometry as well waterjet–hull interaction. In current study, three different propulsion models, namely, multiple reference frame (MRF) model, sliding mesh model and body-force are utilized simulate self-propulsion model. A based on User-Defined Function (UDF) ANSYS Fluent platform prop...

A desire to further comprehend the hydrodynamic characteristics of three-dimensional undulating fin propulsion is what motivates work. First, a high-resolution numerical technique based on constraint immersed boundary method utilized simulate fluid-fin system. The simulation results reveal fundamental variation laws between performance and kinematic parameters. According data, an in-depth analy...

The ship power propulsion system is the "heart" of ship, and shafting core unit system, it an indispensable part ship's torque thrust transmission. operating status directly affects conditions even life ship. Bearing load one most important manifestations state shafting. Focusing on changes in bearing can better study research steady-state meets needs development has great value for practical e...

OBJECTIVE To determine the best test performance and feasibility using a Graded Arm Cranking Test vs a Graded Wheelchair Propulsion Test in young people with spina bifida who use a wheelchair, and to determine the reliability of the best test. DESIGN Validity and reliability study. SUBJECTS Young people with spina bifida who use a wheelchair. METHODS Physiological responses were measured ...

Instrumented treadmills offer significant advantages for analysis of human locomotion, including recording consecutive steady-state gait cycles, precisely controlling walking speed, and avoiding force plate targeting. However, some studies of hemiparetic walking on a treadmill have suggested that the moving treadmill belt may fundamentally alter propulsion mechanics. Any differences in propulsi...

The correct functionality of the upper limbs is an essential condition for the autonomy of people with disabilities, especially for those in wheelchair. In this review we focused on the biomechanics of wheelchair propulsion and we described the instrumental analysis of techniques for the acquisition of wheelchair propulsion.
