Nowadays, Cerebral Palsy (CP) is one of the most common causes of motor disorders in children, with a worldwide prevalence of 1.5 to 2.5 per 1000 births. The most common impact experienced by individuals with CP is muscle spasticity. When muscle spasticity occurs in the hands, individuals with CP face limitations in performing manual activities (MA), making it difficult for them to carry out daily activities independently. Essentially, CP cannot be cured, but it can be managed with various types of treatment. One of the most popular types of treatment is physical therapy and orthotics, such as Constraint-Induced Movement Therapy (CIMT) and Hand-arm Bimanual Intensive Therapy (HABIT). However, studies show that CIMT is less effective in reducing muscle tension. Prolonged use of orthoses can also negatively impact motor development. HABIT therapy is also challenging to perform at home due to limited access to the necessary equipment. Therefore, in this final project research, a mirroring glove design was developed and implemented as a solution to the current limitations in physical therapy and orthotics. The mirroring glove works by reflecting finger movements from the unaffected hand to the same finger at the affected hand. This mirroring glove incorporates a sensing system that uses a flex sensor to detect the position of the finger curvature and a linear motor actuator to move the affected hand. The mirroring glove also employs a proportional controller for position and speed control, with the flex sensor providing feedback. The final test results showed that the designed mirroring glove performed quite well. The obtained range of motion (ROM) data was appropriate and met the functional ROM for manual activities. Additionally, the response time of the actuator to movements of the unaffected hand was relatively fast, ranging from 20 to 40 seconds per hand grip-release cycle.
