摘要 |
Objective: The aim of this study was to examine the effect of
target distance (within vs. beyond arm’s length) on arm and trunk movements
during symmetric bilateral reaching in patients with stroke. Design: Eighteen stroke patients and 18 age-matched
control participants reached bilaterally to press desk bells placed at 90%
and 125% of arm’s length. The kinematics of paretic arm and trunk movements
and trunk contribution slopes were measured in the start, mid, and end phases
of reaching. Results: Target distance significantly affected arm
(shoulder flexion and abduction, elbow extension) and trunk (flexion,
rotation, and lateral shift) movements in patients with stroke. Significant
group differences were also found in trunk contribution slopes in the start
and mid phases of reaching to targets beyond arm’s length. Conclusions: Bilateral reaching for targets beyond arm’s
length may increase shoulder flexion, shoulder abduction, elbow extension,
and trunk flexion, but it may also induce unsymmetric trunk rotation and
lateral shift to the paretic side, as well as early and excessive trunk
contributions in patients with stroke. The findings suggest that for
beyond-arm-length reaching, therapists may restrain the trunk until the end
phase of reaching and prevent trunk rotation and lateral shift to the paretic
side. |
