A variety of methods have been employed to assess different vertebral disorders such as scoliosis,lordosis, and kyphosis. Among these, we can name the utilization of a Posture Screen. A Posture Screen is a network of vertical and horizontal lines on a transparent surface making up a plaid form screen in a wooden or metal frame. Posture Screen brings about hundreds of 5*5 cm cells used to find the alignment of the vertebral column in left-to-right and front-to-back directions. However the Posture Screen is commonly used as a taken-for-granted means of assessing vertebral diversions, it suffers from a number of disadvantages. From among these, we can enumerate its unportability. It is a frame with 1 and 2 meter dimensions. Therefore, it is not an easy task to carry it along even in the clinic. Another drawback of the Posture Screen is its voluminosity. Under certain circumstances, we run short of space in our clinics, and having a large device adds to the dilemma. Furthermore, since the construction of a Posture Screen takes a fairly large amount of workmanship, it turns out to be expensive. As the lines of the crisscrossed screen are only in vertical and horizontal directions and not aligned with the lines of the body, this device does not always prove to be precise. For the above shortcomings of the Posture Screen, we endeavored to design and construct an alternative to it; the new device is the Posture Screen Slide. The Posture Screen Slide is the identical picture of a Posture Screen, which is easily usable with a slide projector. From among the benefits of the new device, we can name its cost-effectiveness. The Posture Screen Slide is a single slide whose price does not amount to large sums. Furthermore, it is not voluminous as one can simply know, and it is readily portable. Elegance is another merit of the Posture Screen Slide. Because of the more compact nature of the Posture Screen Slide, it is much more precise than the Posture Screen.

As a supplementary part of the project, a study was devised to compare Posture Screen Slide and the Posture Screen in assessing the vertebral diversions of 35 patients. The results of Reliability Analyses carried out on the scores obtained from the two measures showed that the Posture Screen Slide had a reliability of .95, whereas the Posture Screen turned out to have a reliability of .74. The t-Test applied to the two figures showed that the Posture Screen Slide's reliability coefficient was significantly larger than the Posture Screen's. An Attitude Likert Scale was also utilized to find out whether therapists preferred Posture Screen Slide to Posture Screen. Results confirmed that there is a positive attitudinal tendency toward the Posture Screen Slide compared to the Posture Screen. The present alternative to the Posture Screen is now getting increasing support from the therapists and the administrators throughout the country, and we have started to receive reports by therapists of its usefulness. As part of the study some of these reports will also be elaborated on.
