These positional feedback systems are especially useful as assessment and rehabilitation tools.. They allow monitoring and amplifying movements (of the head, trunk, pelvis, and knee) to provide a quick assessment of asymmetries, compensations, and variations in patient performance.

Once the problem has been identified, it is possible to target the action on the chosen body segment, guiding the patient towards the acquisition of new strategies.

In addition to this, they are very effective in the structuring of exercises at the beginning of the learning process, when the subject learns the purpose of the task and, guided by the therapist, studies the strategies to use in order to do it in the best way.
