The design and prescription of orthoses can be aided by an understanding of the biomechanical principles of the upper limb.Orthoses are classified into static, dynamic and hybrid orthoses. Upper limb orthoses are more often accepted by patients when there is a well-defined therapeutic programme and when the orthoses provide a desired function that cannot be achieved otherwise. The complexity of the hand, elbow or shoulder requires that orthosis design places equal importance on mechanical efficiency and precision of fit, as comfort is essential for acceptance. Specific training is required to meet the high design and fabrication requirements resulting from small segments (levers), limited soft tissue padding and multiple joints. If the biomechanics can be optimised, then the resulting improvements in kinematics will not only have an immediate effect on gait, joints and muscles, but can also provide a therapeutic environment that can contribute to long-term benefits.
