Methods: This study was a randomized controlled trial. Sixty subjects with first-ever stroke and above six-month post-stroke were randomly assigned to either upper limb vibration group ( ULV group ) or traditional rehabilitation control group.　The subjects of ULV group, besides accepting traditional rehabilitation training, used the vertical vibration of AV-001A to train the upper limbs. At the time of training, the subjects adapted modified plantigrade posture supporting the both upper limbs vertically on the vibration platform. The frequency of vertical vibration of AV-001A was 20 Hz and the amplitude was 1.2 mm. The subjects of ULV group received five minutes vibration training each time for three days per week during eight weeks. The subjects of control group received traditional rehabilitation training only in studying. The subjects of two groups were assessed outcome measures before and after eight-week treatment. The outcome measures included muscle spasticity of paretic upper limb by Modified Ashworth Scale, grasp strength of both hands by JAMAR dynamometer, functional performance of paretic upper limb by Action Research Arm Test, daily use and movement quality of paretic upper limb by Motor Activity Log-28, and motor function by Brunnstrom upper limb recovery stage. Results: Except Modified Ashworth Scale score (P=0.0394), there were no statistical significant differences in grasp strength ratio (P=0.9236), Action Research Arm Test score (P=0.8319), Motor Activity Log-28 QOM scale score (P=0.3411), AOU scale score (P=0.6379), Brunnstrom upper limb recovery stage of proximal part (P=0.6285) and distal part (P=0.4907) between the groups. Conclusion: The influences on grasp strength, functional performance, real-world use and motor function of chronic hemiplegic stroke patients after eight-week traditional rehabilitation and traditional rehabilitation combined with upper limb vibration training were no statistical significant difference. There was relevant influence on spasticity of paretic upper limb.
