Abstract
Contrast to regular able-body tennis players, wheelchair tennis athletes suffer
from significant sports injuries in the upper extremities, particularly in the
shoulder and elbow joints. Proposed causes for these phenomena include
reduced length of kinetic chain, insufficient strength and power, limited and
inefficient transmission of energy, as well as harmful consequent compensatory
changes along the remained body segments and kinetics chain. Improper
adaptations may therefore result in excessive stresses and subsequent injuries in
the shoulder, elbow, and wrist. However, up to present, no study has revealed
suchlike evidence or insight for further implements to minimize the suffering.
Our previous study about sport injury epidemiology in Taiwan wheelchair
tennis players showed that tendinosis and epicondylitis around the elbow joint
are the major problems, and likely originate from improper backhand strokes.
We plan to continue the research with the current study and attempt to feature
the wheelchair backhand stoking biomechanics by comparing the movement
kinematics of regular and wheelchair tennis players. A 3D electromagnetic
motion analysis system and high-g accelerometers will provide movement
tracking, joint liner speeds, angular velocities, angular accelerations, and
wrist-elbow vibrations of both players during topspin and slicing backhand
strokes in standing and wheelchair sitting. Such comparisons and analyses will
provide insight evaluations of compensations and adaptations of stroking
biomechanics in wheelchair tennis, allowing optimal and efficient training,
injury prevention, treating, and rehabilitation.
