One of the most common physiotherapy techniques is joint mobilisation. If you have injured yourself in the course of work, sport, or you simply need your joints rehabilitated, this can work for you. The moment joints become dysfunctional from trauma, and they may fail to perform their designed functions. Joint mobilisation is used to restore the involuntary movements that enable the joints to work to their optimum. This technique is all about performing a to and fro oscillation to restore motion.
Grades
In grade 1, small rhythmic oscillations are done at the start of the range. In grade II, large amplitude oscillations are done within the range but without reaching the limit. In grade III, large amplitude and rhythmic amplitudes are done to the limit and are stressed to the tissue resistance. In grade IV, small oscillations are done at the available motion’s limit then stressed to the resistance of the tissue. In grade V, small but high-velocity thrust techniques are done to force adhesions at the limit of the motion. Note that at this stage; high-tech training is required to acquire the expected results. Grades I and II are mainly used to treat limited pains in joints while grades III and IV are used for stretching manoeuvres.
Amplitudes
Usually, small amplitude distractions are used in cases where no stress is exerted on the capsules. That is common in grade I. Such amplitude equalises muscle tension, cohesive forces, as well as the atmospheric pressure on the joints. Grade II is designed to be tight so as to create enough distraction to the tissues around the affected joints. It is mostly used for the initial treatment to ascertain the sensitivity of the injured joint. In grade III, the amplitude is often very large to ensure that a stretch is placed on the capsules of the joint.
