    Abstract:
    BACKGROUND: Significant results have been shown when an upper limb robot-assisted rehabilitation is delivered to stroke patients. OBJECTIVE: To evaluate the effects of upper limb robot-assisted rehabilitation on motor recovery in stroke patients who underwent a treatment based on a haptic device. METHODS: Thirty-nine stroke patients (twenty-three subacute and sixteen chronic) underwent rehabilitation training by using MOTORE/Armotion haptic system. Thirteen healthy subjects were recruited for comparison purpose.The following clinical outcome measures were used: Chedoke-McMaster Stroke Assessment, Modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FM), Medical Research Council, Motricity Index (MI), Box and Block Test (B&B) and Modified Barthel Index (mBI).The following parameters were computed: mean speed, maximum speed, mean time, path length, normalized jerk, mean force, mean error, mean energy expenditure and active patient-robot interaction percentage.The assessments were carried-out before and after treatment. RESULTS: Significant changes were observed in both groups in the FM, MI, B&B and mean speed. Significant changes were observed in mBI, mean time, mean force, mean energy expenditure and active patient-robot interaction percentage in subacute stroke patients. In chronic stroke patients significant changes were found on the MAS-elbow. CONCLUSIONS: The haptic device used is at least as effective as an existing device used in similar studies.
