OBJECTIVE: To investigate eye-hand coordination in stroke survivors and its
relationship with sensori-motor impairments and hand functioning in daily life.
DESIGN: Cross-sectional study. SUBJECTS: Fifteen subjects with stroke (mean age
62.5 years (standard deviation (SD) 7.1); time post-stroke 5.2 years (SD 3.0))
recruited by convenience sampling. METHODS: A fast finger-pointing task towards a
moving visual target was employed to investigate the differences between the
subjects' affected and unaffected hands in terms of reaction time, movement time
and accuracy. Their sensori-motor impairments in tactile sensation, handgrip
strength, Fugl-Meyer scores and Jebsen Taylor Hand Function Test scores were
measured. RESULTS: Significant differences were found between the affected and
unaffected hands in terms of movement time and accuracy in finger pointing.
Movement time was significantly correlated with tactile sensitivity, handgrip
strength and total Fugl-Meyer score, while accuracy correlated with tactile
sensitivity and total Fugl-Meyer score. Total scores on the hand function test
also correlated significantly with reaction time and movement time. CONCLUSION:
The stroke survivors had poorer eye-hand coordination, in terms of slower
movement and reduced accuracy when using their affected hand. These performance
measures were significantly correlated with several sensori-motor impairments. A
significant correlation was also found between eye-hand coordination performance
and hand function test scores.
