Virtual Reality Therapy
Virtual Reality Therapy is a technique by which the patients of anxiety, phobias and post traumatic stress disorders are mostly treated. The technique basically includes the creation of a reality environment through virtual technology so that the patient could start to prosper in the situation where he previously had any kind of phobia or pressure due to anxiety (Drummond, 2000). Virtual Reality Therapy was first researched by Dr. Max North and since then various new implications are being added into the list of diseases that are being cured with it. Recently Virtual Reality Therapy is also used for the treatment of addiction very successfully.
Virtual Reality Therapy has also been approved to treat the patients with the strokes. The debilitating conditions that are created by strokes make the people to have dislocated joints or other body parts not working. The upper limb functioning is important for the shoulders, arms and neck, creating lots of problems for these patients after being stroke. Virtual Reality Therapy has been able to create such environment that is quite likely to solve this problem. Important thing is to understand what the patients require at post stroke time and how this process of making the moving of the body parts effective. For this reason scientists have created virtual environment which focuses on the home or office environment where the patient has the opportunity to move his body parts more often. Things like picking of glass or pointing towards something can provide relatively better practice for these patients rather than having a nurse physically changing the position of the arms and hands and provide things like physical therapies (Lum et al, 2002). This notion has been very helpful in understanding the exact needs of the patients and then creating the virtual environment as required.
There are various reasons for using Virtual Reality Therapy. First of all, it is one that is the most revolutionary and influential mode of therapies. The patients have the ability to change the environment according the phase they are in, for example, the initial stage required different environments from the middle or say later stage (Tarr, 2002). The first stage is difficult for the patient so only little movement of the body parts is allowed. Moreover, it is the also act as an adjunctive treatment for the upper limb function. The treatment of the stroke is very costly in many parts of the world and having a trainer all the way is very difficult for patient as well. The benefit of using Virtual Reality Therapy is that it might see costly at first but because of its features, in the end the patient feel satisfied with the results.
