ScolioTrack vs PotsiApp

SCOLIOTRACK IS A SAFE AND INNOVATIVE WAY TO TRACK ONE'S SCOLIOSIS CONDITION ◆ Invited to Wall Street Journal 2011 Asia Innovative Awards ◆ Researched and clinically proven to work! ◆ Scoliometers usually cost $150-$300. ◆ Easy and simple to use, no medical knowledge or training needed! The device allows the user to track the progress of the abnormal spinal curves that occur in scoliosis. With the touch of an iPhone the user is easily able to track their month to month progression. This easy-to-use program is suitable for scoliosis sufferers of all ages. Its high degree of accuracy makes this application suitable for professional such as Doctors, Chiropractors or Physiotherapist and simple enough for personal use at home. The device proves much safer than x-ray technology and can be used in between doctor’s visits to track one’s individual condition. “With ScolioTrack, the patient can track the curvature in the spine from month to month by using the iPhone accelerometer, just as a doctor would with a scoliometer,” said Dr. Lau. “A scoliometer is a device that measures objectively the severity of a scoliosis. And so it is with ScolioTrack.” The technology tracks the patient’s Angle of Trunk Rotation (ATR), which is a key measurement in screening and planning for the Health In Your Hands approach to scoliosis treatment. ScolioTrack also tracks a person’s height, weight and photo record of a persons back, both beneficial for growing teenagers or health-conscious adults with scoliosis. ScolioTrack saves all the information in one convenient location and provides touch of the finger retrieval for future checkups. An easy-to-read display shows data output in graph format for ease of tracking changes over time and the new technology is capable of saving and tracking the data of multiple users. With ScolioTrack’s access to the latest breaking news regarding the condition, and its user-friendly support guides, patients can gain an effortless handle on their disorder. FEATURES OF PROGRAM: • Simple, attractive, elegant interface. • Safer and more affordable than x-rays. • Can be used with multiple users and saves their data conveniently on the iPhone for future reference. • Tracks and saves a person’s Scoliosis Angle (ATR), a key measurement in screening for and planning treatment of scoliosis. • Tracks a person’s height and weight, ideal for growing teenagers with scoliosis or adults who are health conscious. • Check your results and Scoliosis changes in beautiful history graph. • Camera function takes a photo of the person’s back to notice any changes to the back visually such as rib humps, hip protrusion, body alignment or spinal deviation and compare it easily with previous photo records. • Displays the latest news feed on scoliosis to keep users informed and up-to-date. • Comprehensive database of frequently asked questions about scoliosis. • Full help and easy to follow guides so anyone can track their scoliosis in the comfort of their own home. ----------------------------------- ABOUT DR KEVIN LAU Dr. Kevin Lau's ScolioTrack is one element of his comprehensive "Health In Your Hands" series for a natural, non-surgical, highly effective and proven method for reversing scoliosis. The other elements include his best selling books "Your Plan for Natural Scoliosis Correction and Prevention" and "An Essential Guide for Scoliosis and a Healthy Pregnancy" which has been translated to 9 languages and an exercise DVD for scoliosis, "Scoliosis Exercises for Prevention and Correction". He is a recipient of the "Best Health-care Provider Award" by the Straits Time and featured on TV prime time news.

By visual inspection of the spine, asymmetry of the back is significant enough to suspect the existence of scoliosis in such cases, to evaluate spinal deformity an X-ray is ordered. Scoliometers could help evaluate the appearance of an asymmetric spine deformity with variable sensitivity and specificity but cannot substitute radiography. It is widely reported in the literature that significant correlations between radiographs and topographic parameters were found. Posterior Trunk Symmetry Index (POTSI) is a useful Index in the assessment of spinal deformity. POTSI Index is very sensitive in revealing any frontal plane asymmetry and could help identify moderate deformities which might otherwise be missed in clinics or physical examination. The Potsi Index is the sum two variables Height Asymmetry Index (HAI) and Frontal Asymmetry Index (FAI). Height asymmetry indexes are obtained as the sum of height differences of the shoulders, axillary folds, and waist creases, and it is normalized with the division of its value by the vertical distance from the C7 vertebra to the baseline of the gluteal cleft. The Potsi App calculates the Potsi Index according to the above mentioned developed topographic method (Suzuki N, Inami ) and offers a way to evaluate external back deformities with noninvasive technique. It is inexpensive and can be repeated indefinite times thus reducing unnecessary x-rays for normal anatomies and mild cases. The app helps the doctor in an outpatient setting to measure all the indexes in a blink of the eye by clicking few points. The app is medical software aimed for orthopaedic surgeons, providing tools that allow doctors to: -Securely import medical images directly from the camera or stored photos. -by marking certain multiple anatomical points over the patients back the app can evaluate back’s symmetry in a few seconds. Eight specific points at the surface of the patient’s back are required. POTSI is relatively simple to measure, even on regular photography of the back. Ideal POTSI is zero, meaning full symmetry of the back surface. The App calculates all necessary elaborate formulas and after analysis the posterior trunk symmetry index(POTSI) is printed. -Save the planned images, for later review or consultation. In a busy everyday practice, measuring all these parameters needed to calculate the Index by the classic way is time consuming and cumbersome. Additional expensive equipment is not needed. Back surface topography by means of structured light in the screening is not needed to mark the necessary points for calculating the Potsi Index. Simple back images taken by phone camera are sufficient. The app offers a very convenient and accurate way to perform measurements. The app could help to monitor objectively the course and evaluate optimally spine deformities. This App is particularly useful especially in clinical settings where you need a quick results without losing time. For specialist a useful tool to monitor quantitatively the cosmetic defect during clinical sessions and to objectively evaluate the effects of surgery on trunk shape. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! The App is indicated for assisting healthcare professionals. Clinical judgment and experience are required to properly use the software. The software is not for primary image interpretation. Reference 1.
