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".

About

SagittalMeter Pro

This app helps medical practitioners measure key parameters of sagittal balance directly from X-ray images using a phone. It aids in analyzing spine alignment for pre-operative planning and surgical outcomes. The tool provides measurements for pelvic incidence, pelvic tilt, sacral slope, and various lumbar and spinal angles.

Highlights
  • Measure sagittal balance parameters
  • Analyze spine alignment
  • Pre-operative planning tool
  • Calculate pelvic incidence, tilt, and sacral slope
  • Measure lumbar lordosis
  • Advanced mode for comprehensive analysis

SagittalMeter is an educative app to easily measure sagittal balance parameters, by directly placing your phone on the sagittal X-Rays. The sagittal balance is an imperative factor to take into consideration for all practitioners treating spine problems and particularly for surgeons during the pre-operative phase. The compensatory mechanisms of a sagittal unbalanced spine may prevent a successful surgery outcome. A fundamental understanding of a correct sagittal alignment is strongly recommended in determining the correct use of fusion or non fusion devices. SagittalMeter enables you to measure 3 fundamental angles which are essential to analyze sagittal alignment (for pre, per and post-operative phases): • Pelvic incidence (PI) • Pelvic tilt (PT) • Sacral slope (SS) Values of lumbar lordosis are also important parameters to describe sagittal balance, so with SagittalMeter you can measure both: • L1-S1 lordosis • L4-S1 lordosis You can do a complete sagittal balance analysis by using advanced mode which extends the previous values with the following measures: • Occipito-C2 angle • Spino-sacral angle (SSA), angle between line from C7/T1 center to S1 plateau center and surface of S1 plateau • C7/T1 slope • C7-C2 angle • Spino-cranial angle (CIA), angle between line from C2 Dens to C7/T1 center and surface of C7/T1 endplate What does it mean? If a patient appears to have sagittal imbalance, this needs to be taken into consideration in the pre-operative planning. Any surgical treatment option should aim at the re-establishment of an ‘economic’ posture, achieved with the restoration of the patient specific sagittal balance. Remembering all theoretical normal values is very important but is definitively not easy and can even be impossible. SagittalMeter gives you the possibility to measure all the parameters in a quick way and gives you the average theoretical normal values for an equivalent asymptomatic healthy patient. How much correction do I need to restore a good balance in daily practice? Before any kind of lumbar fusion including the segment L4 to S1 it is mandatory to analyse the spine balance. If the PT or the lumbar lordosis are not correlated with the value of the PI, an approximation of the amount of correction requested can be evaluated with the FBI technique: C7 translation angle + Femur obliquity angle + PT compensation angle. SagittalMeter enables you to evaluate the FBI index value to get an average correction value.

Verdict

The call

The clearest difference is review sentiment: ScolioTrack at 83% against SagittalMeter Pro's 33%. ScolioTrack also leads on update cadence (every 6 weeks vs every 30 months). SagittalMeter Pro's advantage is rating (3.0 vs 1.0) and price ($9.99 vs $14.99). On ratings volume, ads, in-app purchases and monetization model there is nothing between them.
