The sleeves of the tutors are made of composite thermoplastic, breathable material. They are lightweight and durable, also they have a biomechanically sound, multi-reinforced construction (from high-strength to elastic sections). This provides the upper and lower extremities segments positions and their fixation in the functional position in a wide range of degree of rigidity. This prevents the pathology of displacement in large joints in the event of the ligaments damage or its weakness. Prevent the occurrence of secondary deformations. Reduce pathological settings. Affect the contractures.
