The physical/therapeutic exercise is an excellent therapeutic tool to address multiple pathologies, and especially usual problems in our physiotherapy and rehabilitation consultations: cases of chronic pain or pathologies that tend to recur. The growing increase in scientific research in this field supports the many benefits of an adequate prescription of exercises as part of the treatment with growing scientific evidence.


It has been shown that Physical Therapy Tens Units decreases C-reactive protein and other inflammatory markers such as cytokines, which are present in many pain conditions. The physical exercise would produce a certain inflammation in the short term but a reduction of it in the long term. This relationship with the inflammatory improvement seems to be also related to the lower risk of coronary disease in relation to physical exercise.

Physical exercise has been found to counteract peripheral vasoconstriction and decrease stress, depression and fatigue.

In the case of fibromyalgia, it improves the quality of sleep and can interrupt the interaction between physical stress and other alterations. Because of this, it is considered the therapy of choice.
In addition, through exercise, our brain is able to activate nerve pathways that release analgesic substances, blocking in the marrow those painful stimuli that come from our joints, muscles or any other type of structures. In this link you can see a video where they explained is summarized (activate subtitles).

Neural benefits

We have already spoken in other entries of the cognitive and emotional component of pain, as well as of sensitization at the level of the central nervous system when we are facing chronic pain. The exercise acts here therapeutically exposing the patient gradually to pain and helping him to recover the function despite the pain, which will then also have effects on the reorganization of the cerebral cortex and reverse the sensitization: less pain.

The realization of physical therapy tens units actively involve the patient in their recovery, which acts on the cognitive - behavioral component of pain: the patient knows that he can do something to improve his condition and also does it. The positive reinforcement during the execution of the exercise and on the improvement of the patient at the functional level will support their adherence to the treatment.

Situations of chronic pain can generate a sensitization in the Central Nervous System, changing the threshold of pain and areas of representation of the parts of the body. Physical exercise can help reverse these changes.


Exercise also helps us eliminate some causes of pain and prevent recurrences. In chronic low back pain, active therapy is the one that has been shown to be the most effective in the medium and long term, reducing the recurrence of pain and its chronification. In these pain processes, the most appropriate muscles to maintain the stability of the area are inhibited, stop acting correctly and can become atrophied. Without a reeducation program, they can be replaced by other less effective muscles, and they can end up contracting, because they are more prone to fatigue, and be a source of pain.
