*2.3. Gloreha Sinfonia*

The Gloreha Sinfonia is a robotic device for the neuromotor rehabilitation of the upper limb, which can facilitate the patient in all phases of recovery. It can support the movement of the finger joints in passive, active-assisted and active modes. It consists of a complete set of gloves, braces and accessories for finger mobilization; a dynamic support to compensate the weight of the arm; a stimulating software equipped with 3D animation; a voice guide and audio video effects; a touchscreen PC and an ergonomic table for performing functional exercises and to allow the use with a wheelchair.

The device allows the execution of the following exercises:


Moreover, the robot allows the performance of therapies on patients who are bedridden or in an upright position or seated in a chair/wheelchair. It also allows a constant measurement of motor performance and condition of the patient's hand (active/passive ROM, movement speed, coordination and improvement in the execution of the various

tasks). The robotic glove records all data associated with each patient and allows the operator to monitor the performance of each subject treated. Graphs show the trend of the obtained results exercise by exercise and session by session so that the patient can have immediate feedback on the progress achieved.

Since this is a new technology, there are a limited number of studies in the literature on the use of Gloreha in pediatric and adult stroke patients, which show that the main clinical benefits related to its use are as follows: the maintenance and improvement of the joint range of the fingers of the hands; the prevention of adhesions, contractures and damage from immobilization; the reduction in pain, edema and hypertonia; proprioceptive stimulation, improvement of joint metabolism and lymphatic and blood circulation; the maintenance of functional afferences and the perception of the body; the increase in coordination, dexterity and functional independence; the increase in gripping and gripper strength; and the improvement of visual-spatial and attentional skills [21].
