Objective. Evaluate the effects of a training with the planar robot for upper limb MEMOS 2 (MEchatronic system for MOtor recovery after Stroke) on kinematical indexes: accuracy (Err Area%), mean velocity (Vmean) and Jerk for movement smoothness (JM) in paretic post-stroke subjects. Subjects and methods. 12 patients, 8 men and 4 women aged 51-88 years (mean 65.7 ± 12.4) at the first stroke (11 ischemical, 1 hemorragic; 6 right and 6 left hemiparesis) in sub-acute and chronical stage. At the beginning and at the end of the study Fugl-Meyer (FM), Motricity Index (MI) score, active and passive range of movement (ROM) of shoulder, wrist and elbow and 3 kinematical indexes: (Vmean, ErrArea % and JM), were evaluated. Training consisted in reaching tasks in 5 different scenarios 30 minutes each day for 15 days. Results. At the end of training, FM (p = 0.004), MI (p = 0.01) score, ROM of the shoulder (active flexion p = 0.03), active extension (p = 0.01), active abduction (p = 0.005), passive extension (p = 0.004) significantly increased. Err Area% was reduced in 7/12 subjects (58.3%), JM in 8/12 (66.7%), Vmean was increased in 3/12 subjects (25%) and was reduced in 5/12 (41.7%) (p < 0.05 for each). Conclusions. MEMOS 2 induced an increase in motricity and in active and passive ROM of the shoulder. These results need to be confirmed by a randomized, controlled study in greater and more homogeneous number of patients.
