【Purpose】The purposes of this study were to verify whether metal practice（MP）improve upper extremity motor function and ability of motor imagery in chronic stroke patients.【Methods】Ten chronic stroke patients（age 75.7±5.3）, at least 1 year past from onset, and 15 age matched healthy volunteers（age 70.2±5.7, 7male 8female）were recruited in this study. Stroke patients were allocated to MP group or control group. In the MP group, patients performed video-instructed MP for 2 times per week for 8weeks. The primary outcome measures were Fugl-Meyer assessment（FMA）and revised Motor Imagery Questionnaire（MIQ-RS）. These outcome measures were measured at baseline, 4week and 8week.【Results】MIQ-RS kinesthetic and visual motor image were significantly lower in stork patients compared with healthy volunteers（kinesthetic：patients 35.3±11.1, healthy 46.6±3.1, p=0.001；visual：patients 35.3±9.5, healthy 46.8±3.6, p=0.003）. There was no difference in FMA, MIQ-RS when compared with MP group and control group at baseline. In MP group, there was significant increase of MIQ-RS visual score but was not FMA at 8week. However, FMA score showed a tendency to improve.【Discussion】Training effects were not demonstrated after MP in this study. Although FMA score was not reach statistically significant, MIQ-RS score was significantly increased in particular visual motor imagery. These findings showed that video-instructed MP make visual motor imagery rather than kinesthetic. Further studies should explore what kind of MP has effective for improve upper extremity motor function in chronic stroke patients.
