The biomechanics of wheelchair propulsion in individuals with and without upper-limb impairment.

چکیده
We used an instrumented wheelchair ergometer and 3D motion analysis system to collect joint kinematic and temporal data, as well as hand rim and joint kinetics, in 47 manual wheelchair users (MWCUs) (15 with upper-limb impairment and 32 without upper-limb impairment). The group with upper-limb impairment propelled with a higher stroke frequency and reduced hand-rim contact time, and smaller peak joint angles and joint excursion of the wrist, elbow, and shoulder during the contact phase. They also propelled with a reduced power output and reduced hand-rim propulsive and resultant forces, moments, and joint compressive forces. We concluded that these kinematic and kinetic strategies might be a mechanism for allowing MWCUs with upper-limb impairment to remain independent. Additionally, the reduced joint excursion and reduced magnitude of forces may protect them from the development of secondary upper-limb pathologies.

Purpose of the Work. This study compared the propulsion biomechanics of manual wheelchair users with and without upper-limb impairment. Subjects and Procedures. Fortyseven manual wheelchair users (15 with upper-limb impairment and 32 without upper-limb impairment) propelled an instrumented wheelchair ergometer while a 3D motion analysis system was used to collect joint kinematic and temporal da...
متن کاملEffects of Upper Limb Exercises on Physical Capacity and Heart Function in Quadriplegics
Objectives: Wheelchairs are the prime mobility aid of persons with spinal cord injuries. Manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. The main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...
متن کاملImproved upper-body endurance following a 12-week home exercise program for manual wheelchair users.
This study determined if a 12-week monitored home exercise program would improve cardiorespiratory endurance in a heterogeneous group of manual wheelchair users, which incorporated subsets of individuals with and without upper-limb impairment. Twenty-seven subjects made up two groups of manual wheelchair users: 20 without upper-limb impairment and 7 with upper-limb impairment. Subjects complete...
متن کاملInstruments and techniques for the analysis of wheelchair propulsion and upper extremity involvement in patients with spinal cord injuries: current concept review.
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.
متن کاملUpper-limb joint kinetics expression during wheelchair propulsion.
In the wheelchair propulsion literature, it is common to report upper-limb (UL) joint kinetics to express shoulder, elbow, and wrist loads. Choosing the appropriate kinetic resolution coordinate system (CS) for UL joint forces and moments has become a laboratory-specific process. The differences that arise during interpretation may hinder a clear and broad understanding of UL joint kinetics dur...
