Questions related to Kinesiology
I am an Assistant Professor in Kinesiology Department at California State University San Marcos. I am looking for a few students who would like to obtain their Master's degrees from our department. My research is on Augmented and Virtual Reality-Based interventions for clinical populations. Interdisciplinary backgrounds (kinesiology, psychology, computer science, Unity) are welcome!
I am curious about the difference between ucbl and personalized insoles. I could not find an article on this subject. It is said that the effect is the same in clinics.
As a student, I can't find good but reliable sources for expanding knowledge on the internet, so I'm looking for something easy to understand and read, not scientific journals and papers.
So far I have found - 6
1998 - Blazevich & Jenkins
2002 - Blazevich & Jenkins
2011 - KLIMENTINI et al
2012 - Natalia Romero-Franco et al
2013 - Fernandez et al
2013 - Kamandulis et al
I'm looking for something inspirational which would show me a different side of kinesiology. Something easy to understand but also educational.
Biomechanics face grand challenges due to the intricacy of living things. We need multidiciplinary approach (mechanical, chemical, electrical, and thermal ) to unravel these intricacies. We need to integrate observations from multiple length scales - from organ level to, tissue level, cell level, molecular level, atomic level, and then to energy level) Over these intricacies, their dynamism, the complexity of their response makes it very difficult to correlate empirical data with theoretical models. Among these challenges, which is the most important challenge. If we solve the most important challenge, we could solve most of the other challenges easily.
Many studies suggest that virtual reality rehabilitation can activate the cerebral cortex and improve the function of patients with neurological impairments. Also we hear hippo therapy has a positive effect on the physical function and psychological problems of children with Autism.
May hippo therapy and virtual reality together lead to overall improvements in the daily functioning and quality of life of these children?
confused in between opinions about the relation of internal muscle moment which more linked to eccentric ms contraction and power saving not generation , but others saying that it may cause power generation ?! need explanation

I need to normalize the EMG data for biceps femoris (hamstring muscle group) and vastus lateralis (quadriceps muscle group) using maximum and sub maximal isometric voluntary contraction method. The EMG data pertains to sit to stand task for elderly. Is there any easy exercise or task that elderly could perform (apart from leg curls / extension) for maximum and sub maximal isometric contractions of these two muscles?
I have not been able to find any papers except for one, where any group has been trying to classify movement through EMG across persons, instead of just classifying within the same person.
Within makes great sense for prosthesis, since it only has to work for the one person using it. However, across is very relevant to kinesiology studies of movement.
Has anyone heard of anything like what I'm searching for?
We have some coronal and axial images of thigh muscles which were generated on DTI. We need to do segmentation and fiber tracking of the muscles, and also measure volume and other specific parameters.

Here is a research question I am currently working on, if anyone has knows of any articles that can help me with my research please do let me know.
I know that a large proportion of the muscles in the body are active for a person during her/his gait. But I'm not sure exactly (or approximately) the value of the proportion in percentages with a valid reference.
In the last decade, the concepts of many sciences were varied according the new studies that depend on the measurement tools, and the desired aims.
I would like to know what (and why) the best method is to measure locomotor adaptation to a bilateral ankle-foot exoskeleton that assists plantarflexion, where power is provided by pneumatic muscles.
A subject performs arm movements in a self-paced manner. Movement parameters are captured by sensors and data is streamed in real-time to the computer. There is a fair amount of variability in the sensors readings: in the attached figure, data points captured from 3 sensors during execution of 10 repetitions of 2 types of movement are shown in the attached file.
A couple of important points:
1) In regards to training data: many subjects will be performing the same types of movements, in slightly different ways. Given the small number of repetitions that each subject will be contributing for each class (say, around 10), we want to take advantage of across-subject structure.
2) In regards to classification: Classification needs to happen in "real time", i.e. while data is streamed. We can assume a typical movement duration (say, 5 seconds) to define a "page size" of data to use for the classification, but that can be pretty variable, both within and across subjects. Ideally, the classifier will return a class more frequently, e..g once per second; obviously, at the beginning of a new movement there will be large uncertainty about the class, which will be getting smaller as more data is streamed.
Apart from their apparent difference -- the area of applications differ -- what may be the precise differences between clinical and general gait analysis? To which degree is one associated with another? What are the differences in the techniques involved and what are focussed in each?
There are more studies explaining about chronic pain and inability of patient to repeat the Joint Re position test in both cervical and Lumbar region. I would like to know how can we measure it precisely in clinical set up. Any reliable scale to grade the error?
For testing the sensory threshold in the foot of neurologically affected patients we are using the Semmes-Weinstein Monofilaments.
Now we want to do the statistics on the data but some patients were too insensitive for the strongest filament which they did not feel when we applied it. So we wrote down a value of >6.65 which is not clearly defined as there are no 'stronger' filaments.
How would you treat such a 'value' or piece of information for determining descriptive statistics?
Thanx for your input! Cheers,
I am trying to measure plantar pressure in badminton players when they make the shift to the net for linking with lower body injuries and need to have speed variable at which they are shifting around the court. Does anyone have a similar laboratory study with which to help me?
Thanks in advance
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?
I am going to implement an existing aerobic program on obese adults with strength exercises. The course will provide the test protocol for the evaluation of the strength of certain muscle groups, but my health ideology tends to make me reject test with which you evaluate the loads supported, extrapolation of RM for various exercises to strength machines and so on, even if they are objectively more comparable in the literature. Qualitatively test as PPT or CS-PFP questionnaires on daily activities and more are better, but less comparable. Found that the most important thing is to stimulate an improvement in physical performance of these subjects in the best way to deal with daily activities and reduce the risk of chronic diseases, from the scientific point of view, however the question remains on how to investigate the possible assessments force. Do u think is better a more comprehensive approach, then more oriented to the improvement of the general conditions of the subject, more ethical but less objective or a more analytical approach and therefore more comparable in the literature, such as assessing the strength of the quadriceps by leg extensions?
I am conducting torsional testing on bone samples and I would like to know what maximum torque relates to? I know that stiffness is related to the degree to mineralization but I can't find any information on maximum torque.
Any input will be greatly appreciated. Thank you!
Until now we have investigated the arm proprioceptive control in volleyball players - female, but we intend to develop our researches in enrolled patients in rehabilitation programs ( i.e. post stroke ).
I'm in search of a commonly-used graded exercise test for an upper-body ergometer that determines maximal oxygen consumption.
Somebody proved that the ACL is a C shape through a cadaver study. But it is not correct. I have to disprove that it is not either through staining or through any other technique. Please help me.
Thanks in advance.
Do you know any research which tests the effect of kinesiotape on balance in people with hallux valgus? Thank you.
Can anyone share his/her experience in the degree of elevation of serum creatine kinase (CK/CPK) levels after strenuous physical activities? We frequently observe marked elevated CK levels (more than 200fold) among healthy volunteers related to physical activity (e.g. athletic sports)
I need to measure muscle power of a single inferior extremity. And compare with the other, I would really appreciate if someone have some information to share.
I am interested in comparing different methods for ellipsoid determination. For this purpose, I need the values for the bony landmark from cadaver (which are provided in supplementary material). However, some of the data are missing in the table... Using Van der Helm 1999, I was able to complete the table for all but one important value: the z-coordinate for ThL. Would this be possible to provide us this value?
Although there much literature exists around the statistics area, appropriate books that explain and explicate inferential statistics in vast details are not available.
So I put this question here to utilize the experience of other researchers in this area to recommend a comprehensive inferential statistics book for the area of kinesiology and biomechanics.
I was involved in a research project to assess the patterns of waking and standing from sitting for elderly people using special apparatus and software in Germany. However, I am looking for more input of your view to assess the quality of motion (movement) to build standards for further comparison and application for industry. This will help basic field in medicine, human factor engineering and physical education fields.
What is the point of my question - I have noticed that patients shortly after application have some problem with define their feelings about character and intensity of pain. Of course, it is associated with manual contact and potential sensory disturbances, which requires some time to let fascia back to its natural (but not physiological or correct) condition. Personally, I recommend to my patients, if it is possible, to come back to me in an hour or two to evaluate effectiveness. This phase of treatment can falsify effectiveness of KT application, so in most of cases I can only base on subjective patients opinions.
What is your opinion about this problem?
How do you rate (percent wise) the performance of skills? Is the rating based on the criterion with minimum standard or based on the way the student performs the skills based on skill cues? Do you give a greater score to students for competency on the skill performance such as time and distance or based on skill cues?
How do we know that students have learned a physical education skill? We can assess students using formative and summative assessments but how do we know that students will actually be able to use their skills in real-life, authentic situations? In short, how do we know that our students are competent in the target technique?
Since the book of Basmajian JV, & De Luca CJ entitled Muscles Alive: their functions revealed by electromyography, I have not seen any new interpretation of the influence factors that affect the interpretation of muscle force production. For example, the type of muscle fiber, muscle length, and muscle velocity may influence the association between EMG signal as an electrical and mechanical activity of a muscle.
I'm looking at the comparison of under armour and cotton base layers on core/skin temp, sweat rate, and comfort. However, I do not have the equipment to measure exact sweat production; it would be good to see the point at which sweat occurs as well as monitor how much the participant sweats throughout maybe with a scale of how sweaty they think they are? Or by just noting the point at which I see sweat on the forehead? It seems like both these methods have some issues, so is there any other way that had been shown to be quite a valid test?
I'm looking for data about running kinematics of the upper limb. I would like to know the joints and trunk movements in running in healthy people, but i just find publication about unhealthy or disable people.
Thanks a lot
The adherence to an accelerometer attached to a beld around the leg will be low, so every idea is welcome.
All football players scan and track the football and players on the pitch, however, we know some players react faster and are better at decision making, what is this difference and how is it trained?
This study is made with a 2 year old patient in a constraint induced movement therapy program.
My understanding is that the duration of the CMAP may be too long, so that it reaches the second electrode before completely passing the first. Therefore, as we are measuring the difference between the 2 electrodes we get an artificially low amplitude.
According to the biomechanical basis of human movement book there is a definition for the close pack position "The joint position with maximum contact between the two joint surfaces and in which the ligaments are taut, forcing the two bones to act as a single unit." However, there is no definition existing for congruency and no mention about the difference or relationship between this two.
