In order for the therapeutic process to be successful, it is necessary for kinesitherapists to approach clients in a holistic way. This means that they take into account all segments of the client's psychological and physical characteristics and abilities, and that they do not focus only on the diagnosis. The fact is that every body is different and the same rehabilitation program cannot be effective for several people. The state of the patient's nervous system plays a major role in the entire rehabilitation process. The nervous system is the communication network of our body. The sympathetic nervous system is responsible for preparing body reactions if we are in danger, while the parasympathetic autonomic nervous system is responsible for calming the body, lowering pulse and pressure, absorbing food and nutrients, slowing breathing and activating the immune system. When a client comes who has suffered a traumatic experience, it is necessary to work on his nervous system first, because he is most likely under the influence of the sympathetic nervous system. While the body is under the influence of the sympathetic system, it spends all its energy on survival and basic processes in the body, and any additional work on the body can be recognized as a danger, so it is possible that the therapy may have counter-effects than expected. After some time that the body lives under the influence of the sympathetic system, various physical symptoms begin to appear (Ford, 1997). If the therapists realize that the client's nervous system is dysregulated and this disrupts the general balance of the organism, they can help him regulate the nervous system and balance the sympathetic and parasympathetic system with the help of various tools. Various chronic pains and long-term symptoms are the result of deregulation of the nervous system. Likewise, after the experienced trauma, it is necessary to work with the client to calm the organism and feel safe. If the client is in a 'fight or flight' state during the rehabilitation process, results will be absent or even worsening of symptoms can be noticed. It is only necessary to choose the tools that suit the therapist personally and adapt them to each client individually in order to achieve optimal functioning of the parasympathetic nervous system.
