Influence of rear wheel tire type on wheelchair propulsion biomechanics
… to determine how rear wheel tire type affects wheelchair propulsion mechanics. Four persons with paraplegia and four persons with tetraplegia propelled their own wheelchairs on a roller system at self-selected speed using five different pairs of tires. Upper limb and trunk kinematics, perceived …

Relationship between kinematic factors and muscle activity during wheelchair propulsion
… the kinematic factors and muscle activity during wheelchair propulsion under four speed conditions (90%, 70%, 50% and 30% of individual maximum speed) when using a recreational wheelchair. Ten wheelchair athletes were tested in which the IEMG muscle activity from five muscles (pectoralis major, …

Manual versus power wheelchair propulsion: Quality of life and self-perception
… facilitators and barriers confronting wheelchair user’s mobility and the extent to which manual and power chair are affected differently.

Design, construction and testing of an innovative mechanism for manual wheelchair propulsion
… for people with disabilities who are users of wheelchairs has become a dynamic research area in the past several years. As part of this research, new and innovative mechanisms that give the manual wheelchair users a mechanical advantage, and allow them to operate a standard wheelchair with less …

Construction and assessment of a computer graphics-based model for wheelchair propulsion
Upper limb overuse injuries are common in manual wheelchair using persons with spinal cord injury (SCI), especially those with tetraplegia. Biomechanical analyses involving kinetics, kinematics, and muscle mechanics provide an opportunity to identify modifiable risk factors associated with …

Variability of peak shoulder force during wheelchair propulsion as a function of shoulder pain
Manual wheelchair users report a high prevalence of shoulder pain. Growing evidence shows that variability in forces applied to biological tissue is related to musculoskeletal pain. The purpose of this study was to examine the variability of forces acting on the shoulder during wheelchair …

Exploration of wheelchair propulsion biomechanics in straightforward propulsion, turning manoeuvres and obstacle crossing: The impacts of sex, age and training
A high incidence of injury in wheelchair dependent populations relates to a low mechanical efficiency and a high mechanical load of wheelchair propulsion. The user-related elements such as sex and age as well as training consequences were believed to be main determinants of wheelchair propulsion …

The effect of mass on the kinematics of steady state wheelchair propulsion in adults and children with spinal cord injury
A recent trend in wheelchair design has been the reduction of the mass of wheelchairs. The purpose of this study was to examine the effect of mass on the kinematics of steady state wheelchair propulsion. The mass of test chairs (9.3 kg) was manipulated by mass additions (5 and 10 kg) in two, …

Shoulder pain and cycle to cycle kinematic spatial variability during recovery phase in manual wheelchair users
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 …

Wheelchair Training Program for New Manual Wheelchair Users
Manual wheelchairs are commonly used for everyday mobility among people with lower limb impairments, including persons with spinal cord injury (SCI). Manual wheelchair users often experience pain and chronic overuse injuries in their upper extremities, limiting their mobility and their ability to …

Shoulder pain in manual wheelchair users: towards a multi-disciplinary solution for a multi-faceted problem
… estimated that there are over 2 million manual wheelchair users in the United States. Up to 70% of manual wheelchair users report upper limb pain, which is mainly manifested in the shoulder and wrist. Shoulder pain in wheelchair users is linked to difficulty performing activities of daily …

Design and evaluation of an automatic gear-shifting system for manual wheelchairs
… gears on a bicycle, multiple gears on a manual wheelchair can make it easier to complete many tasks of daily living. We developed an automatic gear-shifting system (AGS) for manually propelled wheelchairs. The AGS has three speeds – first gear: for ascending slopes or traversing compliant …

Design and effects on handrim kinetics of an automatic gear-shifting wheel for manual wheelchairs
Of the 3.6 million wheelchair users (WCUs) living in the United States, 61.6% to 89.5% are manual wheelchair users (MWCUs). Shoulder pain is reported by up to 70% of MWCUs at any given time and has been attributed to the high demand, repetitive stresses placed on the shoulders during wheelchair …

USING ADDITIONAL MEASURES OF HANDGRIP STRENGTH TO PREDICT AEROBIC CAPACITY IN WHEELCHAIR USERS
<p>Manual wheelchair users have been shown to have low physical capacity and impaired ability to perform activities of daily living. Current tests and protocols for assessing physical capacity in wheelchair users have specific boundaries. Measuring handgrip strength (HGS) with electronic handgrip …
