When you have a client stand in front of a postural analysis chart, you can easily notice subtle variations by comparing their body to the grid pattern behind them. This helps therapists develop comprehensive treatment plans and educate patients regarding their existing postural distortions. By periodically taking photos of the same client in front of a posture poster, you can visually document their progress. You can use any phone to take these pictures, with no special software needed, and you can show clients, physicians, and insurance companies the positive impact of the treatment. For increased assessment and documentation efficiency, some posture analysis grid charts also come with a plumb bob kit, which is very useful in measuring deviations.
