An Investigation of Bilateral Symmetry During Manual Wheelchair Propulsion
Studies of manual wheelchair propulsion often assume bilateral symmetry to simplify data collection, processing, and analysis. However, the validity of this assumption is unclear. Most investigations of wheelchair propulsion symmetry have been limited by a relatively small sample size and a focus on a single propulsion condition (e.g., level propulsion at self-selected speed). The purpose of th...
متن کاملUpper Extremity Joint Dynamics and Electromyography (emg) during Standard and Geared Manual Wheelchair Propulsion
Wheelchairs are the primary mobility device for individuals having difficulty with ambulatory activities [1]. In the U.S. it is estimated that 3.3 million people used a wheelchair in 2010 [2], of which 90% used manual wheelchairs (MWs) [3]. However, MWs often lead to reduced independent function and quality of life [4]. Furthermore, shoulder pain and injuries are commonly associated with MW pro...
متن کاملMechanical energy and power flow of the upper extremity in manual wheelchair propulsion.
OBJECTIVE To investigate the characteristics of mechanical energy and power flow of the upper limb during wheelchair propulsion. DESIGN Mechanical energy and power flow of segments were calculated. BACKGROUND Very few studies have taken into account the mechanical energy and power flow of the musculoskeletal system during wheelchair propulsion. Mechanical energy and power flow have proven t...
متن کاملThe effects of rear-wheel camber on the kinematics of upper extremity during wheelchair propulsion
BACKGROUND The rear-wheel camber, defined as the inclination of the rear wheels, is usually used in wheelchair sports, but it is becoming increasingly employed in daily propulsion. Although the rear-wheel camber can increase stability, it alters physiological performance during propulsion. The purpose of the study is to investigate the effects of rear-wheel cambers on temporal-spatial parameter...
متن کاملThe influence of altering push force effectiveness on upper extremity demand during wheelchair propulsion.
Manual wheelchair propulsion has been linked to a high incidence of overuse injury and pain in the upper extremity, which may be caused by the high load requirements and low mechanical efficiency of the task. Previous studies have suggested that poor mechanical efficiency may be due to a low effective handrim force (i.e. applied force that is not directed tangential to the handrim). As a result...
