Background and aim: Stroke is one of the main reasons that would cause disability in adult population. The patient prefers to use his non-involved limb for self-care activities that called disuse learning of involved upper extremity.Constraint-induced therapy is one of the rehabilitative intervention that seems to improve motor ability and functional use of involved upper extremity in some of patients with hemiparesis after stroke. The aim of this study was to investigate the time effects of constraint-induced therapy on functions, coordination and movements of upper extremity of adult patients with hemiplegia.

Materials and methods: In present study, 15 patients with stroke participated in structured therapy sessions (CIT) emphasizing more affected upper extremity in different activities five times a week for 12 weeks and 2 hours a day and non-involved upper extremity were also restrained five times a week for 12 weeks and 5 hours a day

Results: The data was analyzed with paired t-test. The scores  of different  subtests of Fugl-Meyer test  such as shoulder and forearm, wrist and hand movements, coordination and speed of involved upper extremities showed significant differences between pre and post interventions in different time periods (p>0.05). Test scores increased up to 8 weeks but no significant increase was seen after 8^th week .Dexterity measurements by Minnesota Manual Dexterity test  showed significant differences between pre and post intervention in different time periods ( p  < 0.05) with maximum increase up to 10 weeks

Conclusion: The present data showed that constraint-induced therapy could be an effective approach to improve function and overcome disuse learning. The results of this study revealed that scores of Fugl-Meyer and Minnesota Manual Dexterity test  would reflect functional skills improvement.

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.

Background and Aim: Cerebral palsy is a non progressive disorder and the most common movement problem in children. Many children with cerebral palsy are of hemiplegic type. One of the important problems of this children is unilateral upper limb dysfunction, that not using the affected side causes forgetfulness and more problems on this side. In this study, effectiveness of Constraint-Induced Therapy(CIT) and the maintainance of this technique on spasticity and performance of upper extremity in hemiplegic cerebral palsy children 6 to 12 years old have been investigated. 

Materials & Methods: In this pretest - posttest quasi experimental study, 20 cerebral palsy hemiplegic children 6 to 12 years old (15 boys and 5 girls) with  8.7   years mean age were selected. Interventions were performed about 8 weeks and patients were followed for 4 weeks. Spasticity on the affected side in wrist and elbow were tested by Modified Ashworth Scale and upper extremity function by the Box & Block test. The data were analyzed with the Wilcoxon and paired t- tests.

Results: Constraint-Induced Therapy in the affected limb decreases significantly the spasticity of wrist (p = 0.00) and elbow (p = 0.005) and significantly increases performance score (p = 0.00), and the recovery significantly maintained one month after the interventions.

 conclusion: Constraint-Induced Therapy of affected upper extremity could possibly decrease limb spasticity and increase function with two mechanisms: Fierstly, The reduction of not using the plegic side and secondly, neuroplasticity in CNS. This improvement may remain viable in the affected limb.
