FAQ

METHOD FOR RECORDING THE SPINE DURING PHYSICAL EXAMINATION

Where, when and why was the SpinalMouse® system created?

The idea of a device for recording the surface of the spine was influenced by a study performed and published in 1994 by Dr. Seichert and Prof. Senn (Clinic of Physical Medicine and Rehabilitation of the Ludwig-Maximilian University of Munich, Germany). In cooperation with developers from our Swiss partner company, idiag AG, they developed the first prototype of the SpinalMouse®. In 1999 idiag AG launched the first SpinalMouse® devices on the Swiss market. Development was mainly motivated by the fact that there had previously been no methodology or device that allowed a non-invasive, radiation-free, simple and fast – but still reliable and cost effective – assessment of the shape and segmental mobility of the spine.

What innovations does the SpinalMouse® bring for diagnosis and evaluation?

The SpinalMouse® provides an accurate, simple, fast and cost-effective assessment procedure. It allows recording of the spine without the use of radiation or chemicals; this means that there are no harmful side effects. The SpinalMouse® can be used on the same patient as often or as frequently as desired. However, it must be emphasized, that the SpinalMouse® technology primarily addresses the functional aspects of the spine, derived from superficial examination. The SpinalMouse® is not an expert system per se; it gives indications, but it requires a medical expert to formulate diagnoses. In contrast, X-rays, CT scans and MRIs mainly yield structural information thanks to their tissue and bone penetrating technology and are therefore essential for analysing fractures or degenerative diseases, among others.

What are the benefits of the SpinalMouse® compared to other diagnostic methods?

  • Analysis and display of the spine’s shape and mobility in the sagittal and frontal planes
    (global and segmental angles can be defined)
  • No additional costs
  • Equivalent in precision to most common methods, including X-Ray, relevance and clarity of display
  • Simple and fast recording procedure
  • Flexible location, since the equipment is small and therefore mobile
  • User and patient friendly
  • No radiation or chemicals and non-invasive: 
    • No side effects, as from an X-Ray to measure the same angles.
    • Can be used on the same patient as often or as frequently as desired

ADVANTAGES FOR PATIENTS AND CLINICIANS

What kind of information does a recording provide?

The output comprises important clinical information that is needed and can be used by the physician and the therapist in order to formulate the best treatment, therapy or overall care-plan for the patient, and to accurately assess the results or outcomes of any treatments or interventions.

Just some of the clinical information or data include:
- Posture (sagittal and frontal shape of the spine) 
- Sagittal and frontal curvature of thoracic and lumbar spine
- Angle of inclination relative to the perpendicular
- Segmental kyphotic/lordotic angles 
- Pelvic tilt 
- Total back length

Mobility, range of motion (ROM)
- ROM of the thoracic and lumbar spine
- Segmental mobility for all segments starting from T1/2 to L5/S1
- Inclination (total ROM)
- Flexion and extension mobility of hip joints

Postural competence (stability of the trunk)
- Postural reaction when loaded in functional tests (Matthiass test)

Furthermore, the SpinalMouse® software provides the physician with indications for spinal dysfunctional posture or mobility.

Indications for non-harmonic curvature (posture)
- Angle differences of kyphotic or lordotic relation from one segment to the next of > 7°
- Assessment of segment integrity
- Kyphosis instead of lordosis in the lumbar spine in upright position 
(“+” instead of “-” values)
- Lordosis instead of kyphosis in the thoracic spine in upright position 
(“-” instead of “+” values) 
- Lordotic segments in flexed position
- Kyphotic segments in the lumbar spine in extended position

Indications for non-harmonic mobility (ROM)
- Differences in motion from one segment to the next of > 7°
- Dorsal motion of segments when moving from upright to flexed position 
- Segmental ROM values of +1°, 0° or -1°  (segmental hypomobility)
- 0° of ROM of subsequent segments (regional hypomobility)
- 0° of ROM of one segment in both flexion and extension (rigid segment)

What is the benefit for patients?

A back pain patient may obtain valid and reliable information about posture and mobility of the spine. A SpinalMouse® assessment gives indications of malfunctions and spinal pathologies. It is fast, easily performed, uses no harmful chemicals or radiation, has no side effects or contraindications, can be taken at any time or as many times as desired. It visualizes the back in a format that is easy to understand for the patient, the physician, and the therapist. In this way it aids communication, making it easier for the patient to comprehend the cause of his pain. This leads to a much higher degree of patient cooperation, commitment and compliance with interventions, treatment or therapy regimens. Furthermore the SpinalMouse® software provides an exercise catalogue for the therapist to select exercises for an effective training intervention.
SpinalMouse® assessments made during treatment or therapy can document the progress of the patient and provide much-needed quality assurance. Ultimately, this will lead to better rehabilitation results for the patient, medical and healthcare providers, together with lower costs with less time lost for employers and insurance companies.

Could someone without specific back pain benefit from a Spinal Mouse® assessment?

The SpinalMouse® can provide useful information from so-called “screenings” or “wellness checks”.  Spine and back related pain and disorders usually have multi-factorial causes and may develop in nebulous and creeping ways. Regular screenings help to establish baseline information and may alert a person to changes. Bringing such information to the attention of that person’s physician can be extremely helpful in preventing further problems or allowing early diagnosis of existing ones.

HOW IT WORKS

What does the SpinalMouse® do?

The SpinalMouse® is a computer-assisted medical device that can be used to determine the shape and mobility of the spinal column by simply gliding the device manually down the back. 
There is a strong relationship between the surface line on which the recording is done and the midline of the spine in terms of alignment, range of motion, performance and its functions. The Spinal Mouse® device has two wheels arranged on a mobile support that allows the contour of the spine to be tracked. This shape is recorded by sensors that transmit the data to a computer program through a Bluetooth connection.

From the superficial shape, an intelligent recursive algorithm computes information concerning the relative position of the vertebral bodies of the thoracic and lumbar spine, while taking into account the local curvature (kyphotic or lordotic). The final result is an accurate segmental localization of all vertebral bodies as the projection of their midpoints on the superficial contour of the back.

What is the operating principle?

The equipment records the distance plus the SpinalMouse®’s position in the x, y and z planes at any time during the assessment. This information, combined with known anthropometric data about vertebral body dimensions, is used to calculate the relative positions of the sacrum, the vertebral bodies and the angles between them using a complex algorithm.

How does the SpinalMouse® detect each vertebral body?

The SpinalMouse® does not detect the underlying segment when it is simply held against a random segment. If recording is started at an incorrect position (too high or too low) it is not possible for the equipment to correct the error. Therefore it is essential that the examination is carried out correctly (the correct starting and stopping points are fundamental to achieving accuracy).  
Important: The vertebrae are not actually detected; a recursive calculation is carried out. However, data comparisons with X-ray measurements demonstrated good reliability and validity (see Seichert 1999). The detailed assessment principle is part of our industrial secret.

PRACTICE - HANDLING

How to ensure both C7 and S3 are palpated? Additional anatomical points of reference?

To make sure that the position of C7 is correctly palpated, the examiner should ask the subject to extend the head. The examiner keeps his right forefinger on C7 and his ring finger on C6. If C7 is correctly determined, then C7 won’t be, but C6 will disappear during maximal extension of the head. 
S3 can be palpated; however this is somewhat difficult and not always possible. This is why recording must be stopped at the beginning of the anal crest.

Should I push very hard on the SpinalMouse®? Does the pressure affect the result?

The pressure does affect the result. Do not push too hard, but pay attention to keeping both wheels in full, close-fitting and uniform contact with the spinous processes.

Are the markers on the skin just used for demonstration and are not necessary during the actual test?

The markers on the skin are necessary to ensure the correct start and end points are used while recording. They assure the same length is used for all recordings.

How can I clean the markers off the client’s skin – taking sensitive skin into consideration?

If you use eyeliner (cosmetic kohl: the pencil women use for eye makeup) to make the marks, removing them it is easy and skin-friendly. Just wipe them away with your hands or use a little makeup remover.

Must the orange mark and the incision on the housing be lined-up during the test?

No, that indicates the starting position to ensure the neutral position of the green rocker without contacting the outer housing and thus limiting range of motion and flexibility.

Does the fluency with which the SpinalMouse® is run along the spine affect the result?

In 2004 Mannion et al. found systematic errors due to the varying speed of the rolling motion of the device. Since then the SpinalMouse® has undergone improvements in respect of its recording velocity. This should no longer be a problem. If an examiner records too fast or if the movement is irregular, the equipment detects this and a dialogue pops up with information on what to do. 
The most important issue is to maintain the same pace you start with during the whole process of recording the spine from C7 to S3. The conditions for achieving accurate recordings are:
- Exact identification of landmarks as starting and stopping points 
(this was a problem that arose, but was recognised in Mannion’s study in 2004)
- Slow and constant speed 
- Both wheels of the SpinalMouse® need to stay in contact with the skin at all times
- Apply a constant, very light pressure

How can I clean the SpinalMouse® after contact with a patient’s skin during the assessment?

The fastest and easiest way to clean the wheels of the SpinalMouse® is to roll it over a disinfection pad. Please consider the following when choosing a detergent: 
- Use only water and soap when cleaning the plastic surfaces
- Detergents that contain certain ingredients (e.g. alcohol) will tarnish the material or make it brittle
- DO NOT use corrosive or abrasive detergents, sponges or cloths
Do the following when cleaning:
- Be sure the SpinalMouse® “power” is OFF
- Make sure NO liquids run into the SpinalMouse®, this can cause corrosion or internal damage
- Use a lint free cloth moistened only with soap and water
- The docking station should be cleaned after each 50 uses, but at least once a month 
- The SpinalMouse® should be cleaned frequently and as required
- Clean both wheels of the SpinalMouse® after each 50 uses, but at least once every two months: 
1. Pull the small wheel carefully from its attachment. 
2. Clean the small wheel, the axle and the attachment. 
3. Press the small wheel carefully into the attachment until it latches. 
4. Be sure the small wheel can move freely.

How can I disinfect the SpinalMouse®?

We recommend that you disinfect the SpinalMouse® before every patient therapy session, thus prevent¬ing cross-contamination between patients. Clean using a dry or slightly damp cloth. To minimise the risk of explosion, disinfection should be performed according to the rules and guidelines below. We strongly recommend that you use detergents which feature in the list of tested and approved disinfection agents and procedures from the Robert Koch Institute’s department of chemo-thermal disinfection procedures. 
A disinfectant should be used to clean the SpinalMouse®, its surfaces and equipment. 
The SpinalMouse® wheels and the patient’s back should be disinfected before commencing the test.
- Switch the device “OFF” before disinfecting
- The SpinalMouse® and docking station may only be disinfected by wiping them
- The use of sprays is not recommended because disinfectants could enter the interior of the device
- Never use corrosive or abrasive disinfectants 
- Never use disinfectants containing high-strength alcohols 
- Do not use Toluol based resolvents 
- Never sterilize or expose the SpinalMouse® or the docking station to high temperatures 
- Never expose the SpinalMouse® or docking station to any disinfectants that contain alcohol for longer than 5 minutes
- DO NOT wash or submerse the SpinalMouse® or docking station in any liq¬uids or disinfectants
- Use a lint free cloth moistened only with disinfectant
- Use a disinfectant specifically suited for plastics or synthetics

PRACTICE – TESTING

When would you assess the spinal posture paravertebrally?

Some published studies assessed the spine paravertebrally, others only if the subjects were slim and had very prominent spinous processes. We only recommend paravertebral examination in cases where proper recording is not possible because of very prominent spinous processes. Otherwise vertebral examination is advisable.

Do the markers on the spinal processes move away when the patient flexes laterally?

By using the same marker you can detect the difference in relation to the upright position since the skin will move with the vertebrae. Another possibility is to always use the spinal processes, but as these rotate in the horizontal plane as well, they are not easy (and sometimes not possible at all) to detect.

How can I instruct a patient in a seated position?

The patient should be sitting on a stool without a backrest, with his arms hanging freely at the sides of his body and he should be looking straight ahead. From our perspective there is no recommendation for the angle formed by the thigh and hip. 
In order to generate comparable data, try to instruct patients to always adopt the same position. This is basically the key to reliability. 

What is the Matthiass Test for?

Postural competence can be examined using a method modelled on the Matthiass Test. During this test, a defined stress is used to provoke a change in the posture of the upper body that can be determined objectively from the SpinalMouse® recording. The assessment of an abnormal posture involves the evaluation of the extent and location of the postural change in the standing position under stress by raising the arms for 30 seconds. By raising the arms, the centre of gravity of the body is displaced backwards. If the back muscles are weak then this is usually compensated by the backward bending of the upper body axis. The shoulder girdle is displaced backwards, the hips move forward and the lumbolordosis becomes more pronounced.

What is the Spine-check Score© for?

The Spine-check Score© is an overall evaluation of the different functions of the spine (posture, mobility, postural competence) and is assessed by evaluating different criteria (segmental angle differences, paradoxical angles, values out of reference range, segmental/global hyper or hypomobility). So if the score is low, e.g. in flexibility, this represents an overall finding and we do not know if it is caused by a hyper or hypomobile segment for instance – or something else. In order to find specific indicators you must look at the details in the data table or the vertebral graph.

How can I detect axial rotation and therefore scoliosis?

The SpinalMouse® offers an option for providing indirect information about the axial rotation of the vertebral bodies. This is a limited assessment and does not correspond with a direct assessment of axial rotation.
Patients bend forward until the most pronounced hump of the costal arch is reached. Two assessments in the sagittal plane are conducted in this position, at approx. 1-2cm left and right of the spine (see figure 1). A difference in the two assessments shows rotations within a certain region of the back, but cannot indicate axial rotations of a single vertebral body. The assessed rotation is a first indication for scoliosis, further examination for a clear diagnosis might be required.

SPECIAL CIRCUMSTANCES

How to assess if the standard posture contradicts with a patient’s habitual posture?

The posture should not contradict with a patient’s habitual posture. See instruction:
- Stand with the feet about hip-width apart
- Feet are parallel
- Distribute bodyweight evenly on both feet
- Knees should be straight
- The patient should adopt his habitual posture
- The arms should be allowed to hang relaxed at the sides of the body
- Look straight ahead (horizontally).

What to consider when interpreting data of an overweight patient?

The contour line of the thoracic region of the spine in overweight patients is similar to that of normal weight patients. Overweight people are not categorically excluded, but the bias due to the soft tissue must be taken into account. The less additional adipose tissue is present, the more accurate the assessment will be. However, data recordings will still deliver accurate progress measurements – provided the person is not losing or gaining a lot of weight.

Are there age limitations?

Fundamentally, SpinalMouse® recordings can be carried out on patients from the age of 6. It has not yet been tested on children below 6 years of age. This is why there are no reference values so far, but this doesn’t mean that the recording is invalid. Reference values are a guideline to allow interindividual comparisons. If there are no reference values you might still be able to make intraindividual comparisons and relative interindividual comparisons.
 
The gap between 12 and 17 years is a tricky issue because it is well known that during this time, substantial morphological changes to vertebral dimensions occur in the spine. Actually, because the SpinalMouse® System assumes constant vertebra dimensions, reference values for this age group are not as valid as those for patients aged below 12 and above 17. For the group between 12-17 years however, reference values for the age band 18-35 are shown. However, it based on practical experience, that these references values are interlinked with the age group of 12-17 years.

DATA ANALYSIS

Analysis of the data and explanation of the figures (i.e. data table)

Sac/Hip J: Designates the “sacral angle”. This is defined as the angle between the superficial contour line via the sacrum in comparison to the plumb line. Because the connection of the sacrum to the pelvis via the sacroiliac joint is relatively immobile, the sacral angle is an assessment of the position of the pelvis in space (pelvis and sacrum move synchronously). Large positive sacral angles signify pelvic tilting, small positive or even negative sacral angles signify an upright position of the pelvis (pelvic tilting means ventral lowering of the pelvis, an upright pelvis signifies the opposite movement). The change in the sacral angle in the last three columns corresponds to the associated movement in the hip joints.

Thoracic spine: Represents the posture or mobility of the entire dorsal spinal column from Th1 to Th12. Positive angles signify kyphotic posture or flexion, negative angles lordotic posture or extension. The value corresponds to the sum of the 11 segmental angles from Th1/2 to Th11/12. The software adds up the raw data which can result in a minimal difference between the manually calculated sum and the automatically generated sum.

Lumbar spine: Represents the posture or mobility of the entire lumbar spinal column from Th12/L1 to L5/S1. It starts at Th12/L5 because this angle has a generally high mobility. Positive angles signify kyphotic posture or flexion, negative angles lordotic shape or extension. The value corresponds to the sum of the 6 segmental angles from Th12/L1 to L5/S1. The software adds up the raw data which can result in a minimal difference between the manually calculated sum and the automatically generated sum.

Incl.: The connection between Th1 and S1 is referred to as the line of inclination. The angle between this line of inclination and the plumb line is called the angle of inclination or for short, inclination. This has a very graphic meaning; in a “military-upright posture” one is “in the plumb line”. That means that a plumb line dropped from Th1 bisects the trochanter major and runs through the middle of the supporting area of the feet. In this case the inclination is zero degrees. In the usual posture, healthy volunteers often stand bent somewhat forward, so that the inclination is between 5° and 10°. A negative inclination signifies a total bending backwards or a reclination.

What are the reference zones related to?

The reference ranges for patients were provided through standardized assessments on healthy persons without back problems. Reference ranges are matched to gender and age categories. The reference ranges can be defined in the software as 1 or 2 standard deviations from the arithmetical mean of the study population.

Why use angles of >7° or <1° for investigations with the SpinalMouse®?

First of all, let us clarify an important but often misunderstood term: A motional or functional segment consists of two adjacent vertebrae with the corresponding intervertebral disk. The angle between the two vertebrae is usually termed the segmental angle.


The respective software tool is designed to mark jumps in segmental angles from one segment to the other of more than 7°. If you look at the reference values there is a mean standard deviation, depending on the segment, of approximately 2-6°. This is therefore deemed the “normal” variability. The values based on practical experience showed that this statistically “normal” variability and therefore the deviations of angles >7° and <1° are appropriate for practical application. Therefore jumps from one segment to the other that are greater than this variability (e.g. 7°) may be an indication of e.g. hypermobility.

The 1° tool is empirically determined too. If within a segment (between one vertebra and the adjacent vertebra), there is an angle equal or smaller than 1°, then it is marked. This may be an indication of hypomobility of the respective segment.

Important: The SpinalMouse® data must be used solely as a guideline towards achieving a correct diagnosis. As for all other clinical instruments, the SpinalMouse® must not be used blindly in the sense of an "expert system", where deviations from the reference values are uncritically interpreted as signs of pathology. In an individual case, only the complete clinical information available, together with the physician's individual experience, is capable of allowing a reliable clinical assessment to be made. Neither the technical device nor the software is able to interpret the results – only an expert can be responsible and capable of making the most reliable interpretation of the data.

Does the SpinalMouse® detect the Cobb angle as well?

The values generated by the SpinalMouse® software show the angles between lines going through the midplane of the vertebral bodies (see below). Whereas the Cobb angle detects angles with the end plates as reference points. So whilst the measuring points on the vertebrae differ between the methods, a research study (see reference below for further reading) found a strong to very strong relationship between the X-ray Cobb and Spinal Mouse® measurement methods (p < 0.0001), and suggest Spinal Mouse® can be used for research and in the clinical setting as a reliable and easy method, importantly without radiation, for assessing adolescent idiopathic scoliosis.

In the Matthiass Test, why 30 seconds?

The Matthiass Test functions similarly to a standardized test for postural competence. For more details see:
http://www.ncbi.nlm.nih.gov/pubmed/7610701 
Predictive value of Matthiass' arm-raising test. A. Klee. Article in German

What do signs like ")" or "(" mean in viewing results of frontal assessments?

The single brackets indicate whether there is a segmental inclination to the left “)” or to the right “(“. 
) = convex to the right
( = convex to the left
This is similar to the sagittal plane where you have an inclination forwards and backwards. The arrows in the range of motion column (3 columns on the right hand side) indicate whether there is a net angular change to the right “►” or to the left “◄”.

What is the acceptable range of error if I test the same patient several times consecutively?

Acceptable errors for segmental angles are <4° and for the length <20mm (in the data table). Errors can be minimised by giving the patient detailed and precise instructions and by exactly marking the start and end points for recording.

What does it mean if the value of the angle between the sacrum and the hip is out of range (less than min or more than max) in the upright position?

The Sac/Hip value represents the angle between the sacrum and the plumb line. If it is less than min (more versus 0) there is a tendency towards hypolordosis. If the angle is more than max there is a tendency towards hyperlordosis (hollow-back).

Can the thoracic or lumbar spine (in the expert report of the Spine-check Score©) be hypomobile when some segments are hypermobile (red)?

The expert report of the thoracic or lumbar spine corresponds to the REGIONAL analysis. The thoracic or lumbar mobility (thoracic/lumbar spine) might have a range of motion which indicates hypomobility (reference is between 50°-74°). In the same recording the red segments in the table may show an uneven distribution of range of motion between the segments. This is segmental hypermobility which is also indicated in the expert report LOCAL.

CLINICAL PRACTICE

Is there a standardised approach for assessing one test position?

Several different approaches are possible. Multiple flexions or extensions during multiple assessments form a kind of warm-up and thus possibly enhance range of motion throughout the assessments. It is therefore recommended that sufficient warm-up time is allowed (e.g. 1-2 flexion-extension movements) before the assessment commences. Following warm-up, two assessments per position are recommended. To check the quality, compare the two assessments in the comparison mode (optimally, there should be angular differences of less than 4° and the length should differ by less than 20 mm).

Are there any special requirements for an interval period between two tests on the same person?

No. Good opportunities are at the end of intervention periods and after a period where you believe you may be able to detect a change. Do not discourage your patient by making recordings at intervals that are too short, where he/she may not see any result from his/her efforts.

What is the degree of data comparability if participants are tested at different times of day?

A slight diurnal change in spinal column posture and mobility is indeed possible, but this may vary from person to person. Therefore, for scientific purposes, we suggest that the assessments are undertaken at approximately the same time of day and that care is taken to ensure the conditions are equal. If this is not possible, then make sure that the subject adopts exactly the same positions and that the recording is made by the same investigator.

How can I detect underlying pathologies?

The SpinalMouse® is a device for obtaining fast, valid and reliable information about the position, mobility and postural competence (Matthiass Test) of the spine in a format that is easy to understand. It is possible to find indications for malfunctions and spinal pathologies. However, it is NOT possible to diagnose a medical condition with the SpinalMouse® itself. This means that it is too delicate to diagnose e.g. osteoporosis. Taking an anamnesis together with the knowledge of a medical physician or clinician, e.g. physical therapist, osteopath, physiotherapist or chiropractor into account is advised.

Would an abnormally thick spinal disc or a spinal disc extrusion patient affect the accuracy?

If there is only one segment with an abnormally thick disc, the system cannot identify it because of the recording principle. You will see small deviations in this part of the spine. 
If all discs are abnormally thick, then the system will compensate for that with the predicted dimension of each vertebral body and accuracy will not be affected.

EMPIRICAL VIEW & PROGRAM ISSUES

Is there relevant research which indicates the scientific and diagnostic value of an assessment?

There are a number of validation studies regarding the clinical usage of the SpinalMouse®. These show that the SpinalMouse® delivers consistently reliable values for standing curvatures and range of motion (Post, Leferink 2004; Mannion 2004). The reproducibility of assessments obtained with the SpinalMouse® is comparable than that of X-ray evaluations in the inter-rater and intra-rater comparison (Schulz 1999).

How good is validity in the lumbar region?

Validity in the thoracic region is better than validity in the lumbar region. The overlying fat tissue in the lumbar region can produce a different reading compared to X-rays, but only if a lot of additional tissue is present. Since the SpinalMouse® is primarily used for measuring the progress of treatment this does not interfere with the quality of progress assessments, provided the patient does not lose or gain a lot of weight.

Which file format is the most appropriate for backing-up my recorded data?

Open C:\MM60\Data. This directory contains the database Data60.MDB. Save the database file Data60.MDB on an external storage medium and rename the file to avoid confusion, e.g. Data60_02.08.2011.mbd.
The file which you currently use with the software must be located in the folder C:\MM60\Data with the name Data60.mdb.
If you want to use a backup version of your database with the software you must rename it back to Data60.mdb and replace it into the folder C:\MM60\Data.

What is the procedure for deleting unwanted files (from “Select Client”)?

If you want to delete a specific recording or a specific client, mark the recording or client in the overview list and delete it by clicking the bin icon at the top of your menu (or F5 at the bottom).
