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.

CobbAngleApp
This medical software assists orthopedic surgeons in accurately measuring spinal deformities from X-ray images. It simplifies the process of calculating Cobb angles, categorizing scoliosis severity, and monitoring treatment progress. The app offers advanced features to minimize measurement errors and save results for later review.
- Import medical images
- Calculate Cobb angles by marking points
- Categorize scoliosis severity
- Extended measurement mode
- Save measurements and results
- Independent of image inclination

Cobb method is considered the standard for measuring curve size in scoliosis. Cobb angles are always measured from the superior end plate of the most cephalad end vertebra to the inferior end plate of the most caudal end vertebra in the curve. Meticulous line drawings and precise measurements is paramount importance in order to quantify the magnitude of spinal deformities and monitor the success or failure of treatment for scoliosis. The CobbAngleApp is medical software aimed for orthopaedic surgeons, providing tools that allow doctors to: -Securely import medical images directly from the camera or stored photos. -Offers a very convenient way to determine the most accurate possibly way at once. By marking four points at the same X-ray, at each spine the App calculates the Cobb angle. In cases where values are out of normal ranges, the scoliosis is categorized according to measured angle as mild, moderate, severe. To simplify the process and to minimize inter-observer errors usually by not selecting the actual end vertebra, the app offers also in ext mode the ability to draw the vertical reference line through the patient’s sacrum and to identify more easily the end vertebrae s (ext method). -Save the planned images, the measured values and results compared by normal reference databases, for later review or consultation. -The app also is independent from errors produced by image inclination. Especially developed module allows the user to measure accurately without to worry about the tilting of the picture or the X-ray. All information received from the software output must be clinically reviewed regarding its plausibility before patient treatment! CobbAngleApp indicated for assisting healthcare professionals. Clinical judgment and experience are required to properly use the software. The software is not for primary image interpretation. In a busy everyday practice, the examiner have to draw lines in X-rays or in clinical settings, this it is time consuming and cumbersome. Accessory instruments like protractors, hinged goniometers, well sharp pencils, rulers or even transparent papers must be available. The app offers a very convenient and also accurate way to perform most common radiographic measurements for spine, in a blink of an eye in front of your screen. The build in feature of the app, allows results to be categorized may help decide what could be considered normal or pathologic. The app is not a simple goniometer, is an enhanced product which helps to monitor objectively the course of the treatment and evaluate optimally the spine. This App is particular useful especially in clinical settings where you need a quick results without losing time.
