    Do you have experience using inertial measurement units to assess postural balance and center of mass displacement? Where do you place the sensors?

    I'm trying to assess postural balance without using force plates and IMUs seem to be a good choice, but we don't have plenty of publications about this method.

    What is the role of exer-gaming in gait training of stroke patients ?

    Exer gaming has good effect on upper limb function after stroke, but i want to explore the effect of exer gaming on gait. So how it would be beneficial and what type of gaming would help ? 

    Francesco Patti

    All effects when we work in rehabilitation seem positive; ideed if we do something, I can expect an improvement; improvement could be perceived by the patients and not objectivelly measured.

    I would like to know if we have an answer about this focus

    the carry on effect

    the echological value of any rehabilitative treatment

    anatomical and/or neuroradiological changes driven by rehabilitation;

    head/to head studies comparing standard versus exergames or virtual reality approach performed with rigorous methodological procedures

    How can I identify good body posture by using an electronics mechanism?

    Standing and sitting body posture?

    Kadek Heri Sanjaya

    I think you need to define the meaning of good body posture related to the specific activity performed. Then you need to limit what kind of instruments do you want to use to assess the variables you want to measure, such as EMG, force plate, etc. With regard to subjects, the difference due to race, age, sex, etc. are also very important. Basically, you will not be able to find the best posture for all of the population and for all the activities performed. There will be some trade-off.  

  • Vasile Surducan added an answer:
    Could a posture chair (sitting at an angle of around 20degrees to open the hips and straighten the spine) directly improve condition?

    Moreover, not necessarily improve the condition but stop irritation and aggravation and thus improve the patients wellbeing and enabling recovery and strengthening of the supporting muscles. 

    Vasile Surducan

    If the spinal curvature is already caused by kyphosis and scoliosis which already damaged the intervertebral disks, from my own experience (and not a research) in accord with the study above, a posture of about 110 degrees with lumbar support (see the disk pressure.jpg posted by David) is  lowering the pain. The best chair I found is this one: 

    However, even sound weird and sci-fi, the spine illness (except maybe traumas caused by accidents) is a problem of energy flow through the body rather  than caused by an incorrect mechanical position. That's why a person who suffers from spine issues and is permanently nervous and stressed will not find any sitting position without pain.

    How can We measure muscle length in patients with upper cross syndrome?

    exact procedure with validity and reliability. 

    Marcelo Guimarães Silva

    Hi Mr. Urrehman,

    The most important assessment tool is static postural assessment, which will reveal the characteristic protracted scapulae, medially rotated humeri, hyperkyphotic upper thoracic spine, and an anterior head posture (hypolordotic lower cervical spine and a hyperlordotic upper cervical spine). Upon palpatory examination, tightness and the likely presence of myofascial trigger points (TrPs) will be found in the locked short muscles listed above.  So, I think that you should to measure from origin to insertion of the muscle you want taking it to measure that allows maximum stretch, or in the another preestablished measurement level. 

    I hope this helps.

  • Piet van Loon added an answer:
    What are the most common tests to measure the postural regulation and the balance regulation in sports and clinical assessment?

    I search for tests which con mesure these variables in laboratory and field conditions.

    Examles: Timed-up-and-go-test or Tetraxometrie

    Piet van Loon

    Good or normal balancing in otherwise healthy children is dependant on having a true optimal body posture and a optimal stretched nervous system that allows the complete ROM of the whole system. If you are "stiff" the balancing processes cannot achieve optimalisation.  The growth of both systems, the skeleton in its natural curved appearance and the CNS The majority of children do not reach both , mainly by the passive sedentary lifestyle from birth on ( discongruent neuro-osseous growth relations)  The spine as the chassis of our body cannot develop properly to the most natural curvature because of a lack in extension, stretching in backward direction leading to kyphotic changes in first the thoracolumbar spine.

    Along this line of anatomic -physiologic thinking ( Form follows function) there are some simple tests described that can offer insight in this widespread malalignement leading to the biggest socioeconomic burden in countries, where the "western lifestyle"with its chairs and electronic devices.

    We are now in a process to validate these ( simple clinical) tests :1. straight leg raising tests in children, separate and together( to test refectory spasm of the core muscles),

    2 sitting posture test of the trunk with stretched legs on a coach and sitting on the edge ( mobility and correct-ability of deformation)  

    3. bending test forward and assessment from lateral: finger -floor distance as a measure for neuromusculair tightness and assessing the form of the flexed spine< in modern youth almost 70% do have an abnormal  curvature with angular kyphosis ( wedged vertebrae) and round backs ( underdevelopment of the discs) . 

    There is world to be win to get proper balancing as the most natural proof of good postures and a optimal relaxation of the CNS back in growing children. The German orthopedic world around 1900 succeeded in this task by implementing orthopedisc schoolgymnsatics, orthopedic schoolfurniture and widespread knowledge on good bodily development  amongst all parents , schoolteachers and their strong preventive medical apparatus.

  • Anthony G Gordon added an answer:
    What are the signs of dizziness in an infant, and does this have serious developmental consequences?

    The only information I know on this is from West C Lectures on the Diseases of Infancy and Childhood, Lond Med Gaz 1847;39:881-5:

    "If the child be young it will often seem relieved by being carried about in its nurse's arms, and while she is moving will cease its wail for a time, but begin again the moment she stands still.  You will somtimes observe, too, that if moved from one person's arms to those of another, or even if its position be but slightly altered, a sudden expression of alarm will pass across its features; the child is dizzy, and afraid of falling".

    Have these observations ever been replicated?  Could such resistance to movement have serious developmental consequences?  Have similar abnormalities been noted in any specific developmental disorder?

    Anthony G Gordon

    What about long term effects in developmental disorders, other than congenital deafness, or even in the normal population?

    In order to identify individuals who have poor posture, which diagnostic method is available?

    To measure the effectiveness of the use of a corset, first we want to identify individuals with poor posture. We need a reliable diagnostic method to do so, the risk groups are often Kyphosis individuals.

    Thank you in advance for your reply.

    Piet van Loon

    dear Tugba,

    van Wingerden is right in advising looking for causes.Poor posture has as the first and the most important characteristics, that the thoracolumbar spine is kyphotic starting at a young age , first while sitting ( like Gameboyback,) . The deforming power of sitting and slumping becomes a hot topic now. Other characteristics are the slumped shoulders and the ears hanging in front of the center of the shoulder. Also the neuromuscular tightness ( bending test, SLR test ) show deficits. Depending on age and seriousness exercises in extension or correction at the TL spine in braces ( children) of corsets with this TLI principle .

    In contrast with earlier believes, this type of bracing or corset does not diminish muscle activity , while it resets especially the abdominal muscles into physiologic pretension needed for proper function. as it does to the diafragm. Full muscular activity is preserved in walking .  We described some tests on tension and on the etiology.

    Good Luck

    What are the latest hypotheses and publications on the cerebellar postural control for bipedal stance?

    Neurological control of bipedal posture

    Shirin Yazdani

    as you know, cerebellar control of posture is mainly based on the coordinated activity of the cerebellum, brainstem reticular formation and vestibular systems, providing the control of  posture and body balance.Cerebellar damage in humans results in increased standing postural sway, hypermetric postural responses and prolonged muscle activity.
    Previously, we assessed the postural control of patients with low back pain and healthy controls by altering the systems involved in balance control (eyes open vs closed , vestibular and properiocetion manipulation) before and after the 3 months balance training and therapeutic exercise.

    In recent researches, perturbation-based balance training for preventing falls, movement strategies for maintaining standing balance during arm tracking in people with multiple sclerosis, effects of a predefined mini-trampoline training program on balance, mobility and activities of daily living after stroke, and so etc.... were done.

  • Piotr Gawda added an answer:
    What is the gold standard method for spinal curvature measurements?

    There are many methods for measuring the spinal curves such as radiography (Cobb angle), flexible ruler (flexicurve), Spinal mouse, and etc. Also there are many publications about the validity and reliability of the measuring methods. However, it has been mentioned some negative points about using them. So, what is the best and safest method for spinal curves measuring, specially in person with spinal postural deformities?   

    Piotr Gawda

    Considering the methods of spinal curvature measurements I agree that radiographic (Cobb angle) one is widely used in practice however this method gives incomplete data about spatial orientation to call it "gold standard method".In my opinion combination of radiographic measurement and postural characteristic (COG sway velocity) is good enough to properly asses spinal deformities

  • Pedro Berjano added an answer:
    Is there any way to measure anterior-posterior pelvic tilt and when to see it as normal or as related to lordosis - kyphosis ?

    I have seen a lot of people have anterior pelvic tilt, others a slight others a lot more. How can i know where this can a problem that must be fixed or its no problem and i should not try to fix it? I mean is there a standard angle? If yes it is the same for males and females? 

    Pedro Berjano

    You can measure pelvic tilt by the pelvic tilt angle on lateral standing X-rays, and measure also the pelvic incidence angle in the same X-rays. 

    Pelvic tilt (angle between the vertical line and a line traced between the center of the S1 endplate and the center of the hip joints axis -defined as the central point of the line between the center of the left and right femoral head-) in normal individuals is almost always lower than 21°. Higher values correlate to worse function and more back pain, and are usually due to posterior tilt of the pelvic to compensate for insufficient lordosis. 

    Additionally, a fair correlation between pelvic tilt (PT) and pelvic incidence (PI) has been found and described by Vialle. They published a formula to calculate the expected value of PT as a function of PI: PT=0,37PI-7°

  • Afonso Shiguemi Inoue Salgado added an answer:
    Is there a force plate input test with visual step reported in English language literature?

    In practice in Russia test with visual step input is often used. The test consists in the following. The person stands on a force plate, look at the screen on which the target and movement of the center of pressure (COP) of the person are displayed. COP position is given by force plate indications. At the test beginning the center of a target corresponds to average COP position on the basic plane. During test target position make change and the person ask to change quickly body position due to change of an ankle angle so that to combine COP image with the center of a target and to hold it in a vicinity of the last.

    Whether the analog of this test in English-speaking literature, and what correct name of this test is described?

    What Yallini has attached (TekScan suggested procedure) is the best, and as suggested the wear and tear should be considered (repeated calibration before each use). However, some of their sensors come with specific software (say, F-scan for in-shoe plantar pressure analysis) that takes care of this repeated calibration procedure.
