A Modified Dynamic 3-Dimensional Tri-planar Corrective Brace for Management of Torticollis - A Case Study

Torticollis is a congenital condition caused by the shortening of the sternocleidomastoid muscle, leading to abnormal head positioning with lateral tilt and contralateral rotation. Traditional cervical orthoses, such as static rotational control cervical braces, often lack adjustability, comfort, and dynamic functionality. This study aims to design and develop a lightweight, adjustable, and dynamic 3-dimensional tri-planar corrective torticollis brace. The proposed orthosis provides gradual correction in all three planes, relieving neurological conditions associated with compressed nerves and chronic pain, while enhancing the patient’s ability to perform routine activities. The brace realigns the cervical spine and cervical-occipital joint, redistributes gravitational stress, and maintains the head in the desired posture through its biomechanical design. Results indicate improved daily living activities, reduced upper extremity pain, and a significant decrease in contracture angle from a mean of 30° to 10°. Key words: Torticollis, cervical orthosis, 3D tri-planar correction, biomechanical design, posture correction, cervical spine realignment.
