“…Our results confirm that the motor impairment in the upper limb of post-stroke patients improve after the rehabilitation based on a robot-aided therapy, both in chronic and subacute subjects, as demonstrated by several previous studies [22], [23], [24], [25], [26], [27], [28], [29], [30], even if clinical scales seem to detect a better recovery in subacute patients than that observed in chronic patients. The analysis of biomechanical parameters shows that also the velocity of the arm movement improves after the robotic training, in both groups (Fig.…”

The aim of this article is to propose a methodology for analyzing different recovery mechanisms in subacute and chronic patients through evaluation of biomechanical parameters. Twenty-five post-stroke subjects, eight subacute and seventeen chronic, participated in the study. A 2-DoF robotic system was used for upper limb training. Two clinical scales were used for assessment. Forces and velocities at the robot's end-effector during the execution of upper limb planar reaching movements were measured. Clinical outcome measures show a significant decrease in motor impairment after the treatment both in chronic and subacute patients (MSS-SE, p<0.001; FM, p<0.05). Movement velocity increases after the robot-aided treatment in both groups. Mean values of forces exerted by subacute patients are lower than those observed in chronic patients, both at the beginning and at the end of robotic treatment, as in the latter the pathological pattern is already structured. Our results demonstrate that the monitoring of the forces exerted on the end-effector during robot-aided treatment can identify the specific motor recovery mechanisms at different stages. If the pathological pattern is not yet structured, rehabilitative interventions should be addressed toward the use of motor re-learning procedures; on the other hand, if the force analysis shows a strong pathological pattern, mechanisms of compensation should be encouraged.

“…A robot-assisted device can provide repetitive, task-specific activities that can be graded to challenge the user to promote motor learning without the direct one-on-one oversight of a therapist (Kwakkel et al, 2008;Masiero et al, 2009;Matsuo et al, 2013). An emerging body of evidence has shown promising results with improved motor recovery and improvement on QOL measures with the use of robotic devices after stroke (Bovolenta, Sale, Dall'Armi, Clerici, & Franceschini, 2011;Page, Hill, & White, 2013;Posteraro et al, 2009). Page et al (2013) found that after 24 sessions with an upperextremity (UE) robot-assisted therapy device, people with chronic stroke made favorable gains in the ADL and Instrumental Activities of Daily Living (IADL), Hand Function, and Stroke Recovery domains of the Stroke Impact Scale (SIS; Duncan et al, 1999), a QOL measure used after stroke (Page et al, 2013).…”

OBJECTIVE. The aim of this study was to determine the effects of home-based robot-assisted rehabilitation coupled with a home exercise program compared with a home exercise program alone on depression and quality of life in people after stroke. METHOD. A multisite randomized controlled clinical trial was completed with 99 people <6 mo after stroke who had limited access to formal therapy. Participants were randomized into one of two groups, (1) a home exercise program or (2) a robot-assisted therapy + home exercise program, and participated in an 8-wk home intervention. RESULTS. We observed statistically significant changes in all but one domain on the Stroke Impact Scale and the Center for Epidemiologic Studies Depression Scale for both groups. CONCLUSION. A robot-assisted intervention coupled with a home exercise program and a home exercise program alone administered using a telerehabilitation model may be valuable approaches to improving quality of life and depression in people after stroke.

Abstract. The main goal of this paper is to describe a method for the assessment of the motor performance in post-stroke subjects who have been undergone a robot-aided upper limb rehabilitation treatment.The motivation for adopting such methodology relies on the need of quantitative methods for the evaluation of the effects of robot-aided rehabilitation treatments, which assumes great importance from the clinical point of view.The method is based on the analysis of biomechanical parameters computed from force data recorded during the execution of planar reaching movements. Data from 17 chronic post-stroke patients and 5 healthy subjects were analysed.The results show the effectiveness of the proposed method, which can contribute to quantitatively evaluate the effects of a robot-mediated therapy on the upper limb of chronic post-stroke subjects.
