The aim of this study was to investigate eye-hand coordination in
stroke survivors while sitting and standing and its relationship with
sensorimotor performance. DESIGN: This was a cross-sectional study conducted at
university-based rehabilitation center. Fifteen stroke survivors performed a fast
finger-pointing task toward a visual target moving at 10 cm/sec from the
contralateral side toward the moving arm in sitting and standing positions.
Reaction time, movement time, and pointing accuracy were measured.
Anteroposterior, medial-lateral, and total sway were also measured during the
standing trials. Several sensorimotor impairments were also measured to correlate
with the eye-hand coordination performance. RESULTS: A significantly shorter
reaction time was found in the nonparetic than the paretic side when standing,
but not when sitting. The movement time of the paretic side was significantly
faster when standing when compared with sitting. Fast pointing with the paretic
arm significantly increased the total sway path and anteroposterior displacement
while standing compared with pointing with the nonparetic arm. Movement time of
the paretic arm was negatively correlated with handgrip strength and the strength
of the elbow flexors and wrist extensors. CONCLUSIONS: The movement time of
eye-hand coordination of stroke survivors was affected by postural stability.
Correlations were found between pointing performance and several sensorimotor
impairments.
