RESUMO
Objectives: Functional limitation of the upper extremity (UE) in obstetrical brachial plexus paralysis (OBPP) restricts a child's participation in daily living and social activities. In treatment, the participation of UE in rehabilitation is important. Constraint-induced movement therapy (CIMT) is a promising rehabilitation approach that is used to improve the UE functions of patients with neurological dysfunctions. Methods: This single-blinded randomized controlled clinical trial includes 30 pediatric patients diagnosed with chronic OBPP aged between 2 and 12 years. The patients were divided into two groups as a modified CIMT group and a control group. Patients in both groups underwent classical rehabilitation treatment 4 times a week for 8 weeks. Range of motion (ROM), stretching, strengthening, and proprioceptive exercises were given to both control and CIMT group. The patients in the CIMT group had to wear constraining arm slings 2 h per day and 4 days a week for 8 weeks. The patients were evaluated both before and after treatment using the Mallet classification system and the Melbourne unilateral upper limb assessment-2 (The MA2) scale. Results: In both groups, the Mallet and MA2 scores significantly increased after the treatment process. However, the percentage of improvement was higher for the CIMT group. Conclusion: Modified CIMT improves the joint ROM and the functional use of the extremity among OBPP-diagnosed children. This improvement is greater in the CIMT group compared to the improvement in the control group. Implementation of CIMT in a routine rehabilitation process may be helpful.
