Background and Aims: Robotic rehabilitation therapy has been tried as a novel technology in field of upper extremity rehabilitation of stroke patients. However, the previous trial revealed the additional effect of robotic therapy compared to conservative therapy. We aimed to investigate whether the same intensity robot-assisted arm training(RAT) was more effective on the recovery of motor and improvement of upper limb function than conventional occupational therapy(COT) in subacute first-ever hemiplegic stroke patients (Fig.1). Methods: The clinical assessment included Fugl-Meyer Assessment(FMA), Motricity Index(MI), Functional Independence Measure(FIM), Motor Function Test(MFT), Wolf Motor Function Test(WMFT), Trunk Control Test(TCT), Maximal Voluntary Torques(MVT), Visual Analogue Scale(VAS) for pain, and Active Range of Motion(AROM). The repeated measures ANOVA was used to compare the results of longitudinal analyses between two groups (SPSS Inc., Chicago, IL, USA). Results: The all parameters measured at baseline did not differ between two groups. Both groups showed significant improvements in FMA, MI, FIM, MFT, WMFT, TCT, MVT, and AROM after treatment (P<0.05). However, the results of longitudinal analyses during the 8-week study period did not show significant difference between two groups except VAS in AROM (p=0.011) and AROM of shoulder adduction (p=0.032) (Table 1). Conclusions: This study did not agree that robot-assisted arm training combined with conventional occupational therapy in subacute post-stroke hemiplegic patients may be superior to the same intensity conventional occupational therapy.
