The cardinal signs of inflammation will help to determine when therapists can begin to introduce tension to injured tissues. Reduction of most or all of the cardinal signs of inflammation is a good indicator of when to begin to mildly stress tissues. The recurrence of any of the signs following the introduction of tension usually indicates that the tension applied exceeded the tolerance of the tissue. The degree of tension is inversely proportional to the extent of injury. Common sense would dictate that therapists introduce a small amount of tension initially, evaluate the tissue response, then proceed as indicated.
Therapists can apply tension in a variety of ways.
Tension can be manual, such as with friction massage, joint mobilization, or exercise. It can also be provided mechanically by rubber bands, weights, or other methods of resistance. Think Anatomically, Biomechanically, and Functionally Occupational therapists and physical therapists must have a solid foundation in anatomy and biomechanics to develop effective interventions. They should always consider the anatomy of a region and visualize the various structures that they are rehabilitating. Therapists should apply biomechanical principles to their treatment.
