3/22/2016 Methods of Postural Assessment Used for Sports Persons
Discussion Go to:
The commonest method which is used to assess posture is the visual observation method, since it does not require
any equipment. With this method, quantitative data cannot be obtained, minor postural alterations cannot be
detected and it possesses a poor interrater agreement. All these limitations discourage the use of this method for
scientific research purposes. Use of a plumbline and a postural grid for the evaluation of posture too, is very
common, owing to its low cost and simplicity. This method too cannot be used to produce quantifiable data.
Goniometers are also used for the assessment of posture, despite difficulty in maintaining the arm of the goniometer
parallel with the horizontal. The “gold standard” method that exists as of now is the radiographic method. But its
cost and risk of exposure towards harmful radiations promote the use of noninvasive methods for the measurement
of postural variables. Offlate, photogrammetric method has come into existence, which is a further advancement of
photographic method and its use as a method for postural evaluation is indisputable. This method has been
compared with the visual method, goniometry and radiography. Reliability of this method too has been tested.
Variety of other methods exist, such as “posturometer”, “flexiruler”, Moiré topography and electromagnetic
tracking devices for 3dimensional analysis of posture. However, 3dimensional methods are costly and not
ubiquitous.
Conclusion Go to:
Photogrammetric and radiographic methods seem to be the most reliable methods which can be used for obtaining
values which are related to posture. However, the latter has its own disadvantage of exposing the subjects to
harmful radiations. Thus, the use of photogrammetric method is recommended for future studies which will focus
on posture evaluation.
