I am providing physical therapy treatment in addition to Botox injection for a patient with Idiopathic Spasmodic Torticollis. I would like to know any valid method to determine the cervical lateral tilt and axial rotation..
This patient presents with combination of right cervical lateral tilt with left rotation.
I find difficult to measure it. since, it is not isolated movement.

(considering that I use triaxial accelerometers) Some papers use L3 or L5 spinal process, but there is a lack of references about that parameter.
Pelvis or center of L5/S1. I support what Alan said, the David Winter book is a very good reference. Also, if you like, take a look at this work:

- Piet van Loon added an answer: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.
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.

- Shirin Yazdani added an answer:What are the latest hypotheses and publications on the cerebellar postural control for bipedal stance?
Neurological control of bipedal posture
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.Following
- Priscilla Morais added an answer:Do you have experience using inertial measurement units to assess postural balance and center of mass displacement? Where do you place the sensors?

- Priscilla Morais added an answer:Is balance training important in non-athletes adults?
It is widely studied the importance of balance training in older people, but what evidence is there to train balance in youth and adult non-athletes? Any paper to review it? Thank you so much.
Even if balance isn't an issue on healthy young adults, balance training can promote better postural stabilization and prevent injuries. Training the anticipatory and compensatory mechanisms, the whole musculoskeletal system will be ready to stabilize itself and the joints and tendons won't suffer.Following
- 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?
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 deformitiesFollowing
- 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?
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?

The pressure on the foot sole varies in standing and walking. It is different in the different regions of the sole even during the rolling of the foot when one steps forwards. In standing position the greatest pressure is distributed on the heel , head of first metatarsal and head of fifth metatarsal . These are the classic support points of the foot described by E. Haas some 90 years ago. Since that time the statics and dynamics of the foot is comprehensively studied and you may find abundant propedeutical literature on this topic.Following

- Grzegorz Sobota added an answer:Does anyone have the MATLAB code for the decomposition of the center of pressure to its fraction of rambling and trembling?COP decomposition has been made by some MATLAB codes such as "Cubic spline function" to obtain an estimate of rambling trajectory. Trembling is the deviation of COP from rambling trajectory. I was wondering if the whole process can be completed by this function?Hi Mohammad,
what do You mean "completed by this function"? Function of "cubic spline"?
As you can see in the work Zatsiorsky and Duarte (2000) cubic spline function is just one of the steps to obtain from COP a rambling and trembling trajectory.
The cubic spline function allows you to create a rambling trajectory based on the information about the position of the COP in the IEP (at times when the horizontal force is zero).
- Bruno Bonnechère added an answer:How can I connect a Nintendo board and a Kinect camera to a laptop?A Nintendo board is a board which can be used as a cheap-portable device to measure COP transition in certain conditions (and with a higher rate of error in comparison to a force platform). A Kinect camera is an IR camera sensor attached to X-box console which has been used recently in research to track center of mass.For the Kinect you just have to plug it in the computer with USB. Currently it is only possible with the old Kinect (360) not the new one (Kinect One).
Then you have two options: if you use the Kinect for Xbox you have to install Kinect SDK and Windows Developper Toolkit (http://www.microsoft.com/en-us/kinectforwindowsdev/Downloads.aspx). If you use the Kinect for Windows you don't have to install anything.
For the Balance Board you simply have to connect it to the computer with Bluetooth connection.
