TL;DR: A three degree-of-freedom (3-DOF) exoskeleton design of a thumb is provided for greater security in which the patient feedback is evaluated in order to make necessary automatic changes in method of treatment (changing speed and force).
Abstract: Stroke is one of the most common diseases among the elderly with high personal and societal costs. In recent years, robotic rehabilitation for stroke has become an active area of research for assistance, monitoring and qualifying the rehabilitation treatments. The key issue needed for improving rehabilitation system is that patient feedback should be taken into account by the robotic rehabilitation systems for providing rehabilitation treatment. Changes in the delivery of rehabilitation treatment are an important issue since the patient or specialist should be able to express their sense about doing things and apply the needed improvements in treatment. Therefore, in this dissertation, a three degree-of-freedom (3-DOF) exoskeleton design of a thumb has been provided. Then, a control structure is provided for greater security in which the patient feedback is evaluated in order to make necessary automatic changes in method of treatment (changing speed and force). In this design, a versatile framework with high performance is offered to simultaneously control thumb force and position regarding the patients’ feedback. This helps to keep the patient in the treatment process, reduce interventions and therapist caseload, effective automatic transmission of treatment and pain relief during the course of treatment. The results of the study suggest that the force and speed on the thumb can be changed during the rehabilitation period according to the patient's needs. This advantage can be considered as an essential step to improve and increase the efficiency of rehabilitation

TL;DR: Data showed that constraint-induced therapy could be an effective approach to improve Activities of Daily Living of stroke patients and emphasis on more use of involved UE and overcome disuse learning.
Abstract: Background and aim: Most of the rehabilitation treatments for hemiplegic patients focus on compensatory strategies to promote independence in ADL by any means for restoration of upper exterimity (UE) function . Patients were taught to use the unaffected UE and various assistive device for ADL. In contrast, Constraint-Induced Therapy (CIT) treatments discourage the use of unaffected UE and encourage the use of the hemiplegic arm . The aim of this study was to investigate the effect of constraint-induced therapy on ADL of adult hemiplegic patients. Materials and methods: This study is an interventional study. In present study, 15 patients who had hemiplegic arm following stroke, participated in constraint-induced therapy sessions emphasizing on more affected UE in different activities five times a week for 8 weeks and 2 hours a day. Noninvolved UE was restricted with a special sling for 8 weeks and 5 hours a day. Result: The measurements of self care activities, mobility and total score of stroke patients were evaluated with Barthel-Index. The date showed significant differences between mean score of pre and post interventions (p<0.001). Functional measurements of upper extremity in ADL by using Arm Function Test showed significant differences between mean score of pre and post interventions (p<0.0001). Conclusion: Presents data showed that constraint-induced therapy could be an effective approach to improve Activities of Daily Living of stroke patients and emphasis on more use of involved UE and overcome disuse learning.
