The design of effective shoulder orthotic devices has increasingly made use of polymeric materials because of their versatility, durability, and biocompatibility. This review illustrates polymer chemistry role in constructing an orthotic device for shoulder subluxation, which is a commonly occurring post stroke or injury condition. Proprietary design elements such as polypropylene are rigid yet moldable which help in anatomical formulating for joint stabilization. On the other hand, rubber elastomers, medicinal rubber and ethaflex help improve comfort provided to the patient with regard to pressure and shock absorption around the shoulder and upper arm. These viscoelastic materials also reduce friction between skin surfaces which improves adherence to the device. Modern designs of orthoses include the new feature of electrodes being embedded within the cushioning layer made of polymers. These parts assist in pain alleviation by means of Transcutaneous Electrical Nerve Stimulation (TENS), which is a type of non-invasive electrotherapy. Functional polymers are used to coat the electrodes so that they will have insulation, protection, and flexibility. The combination of rigid and soft polymers facilitates transfer of forces by a three-point pressure system of dominant forces to the frame, resulting in reduction of discomfort when moving the arms during subluxation treatment. Sutureless self-tightening devices that are flexible achieve better movement adaptability compared to conventional orthoses. Anticipation of smart polymers, biodegradable matrices, and antimicrobial surfaces will result in orthoses that have responsive, eco-friendly, and therapeutically useful properties. Polymer chemistry aids in the progression of orthotic, or prosthetic, devices because it simplifies the industrial fabrication of shoulder orthoses through the integration of design, function, structure, and patient.
