Neurologic Gait Disorders - Science topic

Gait abnormalities that are a manifestation of nervous system dysfunction. These conditions may be caused by a wide variety of disorders which affect motor control, sensory feedback, and muscle strength including: CENTRAL NERVOUS SYSTEM DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; or MUSCULAR DISEASES.

Hello to everybody,
I am new to the field of the Gait Analysis, but I did lots of study to explore this topic as this is the first part of my project proposal. Thus, the second part consists of developing a system that can extract gait features (like cadence, stride time etc) from a video, but I have no idea where to start because I have not found any source code yet. The main idea is extracting gait features related to PD from healthy people (Training Set) and, in a later moment, from PD people (Test Set), so that new gaits will be classified as abnormal.
Basically, here is explained the main idea: a classifier takes in input a video of one healthy person performing his/her gait, and the classifier extracts relevant features; this is executed multiple times with different people (generating the Training Set). At the end of the supervised learning, the classifier takes in input a new, unseen person gait and it has to evaluate if the person is healthy or ill (if ill, what disease); this is executed multiple times with different people (generating the Test Set).
Do you know any projects available that can carry out my task, or suitable to my situation? Of course, any programming language is accepted (Python and MATLAB are very welcome) as well as any datasets (either existent or self-made).
Thank you for your availability and patience.
Kind regards,
Luigi Manosperta

I am planning a study on freezing in patients with Parkinson’s disease. I need basic parameters including and especially time taken to initiate walking.
What is the most affordable way to conduct such gait analysis? Insoles? Affordable gait mats?
Thanks for your response in advance,
Siddharth.

Answer
The cheapest is likely to be either a 2D video camera and free software.
The trouble you will find is placing a camera in the correct location. Using a treadmill is unlikely to be a good move with this patient group, therefore you will need multiple cameras to catch more than a step or two initiation of gait.
You could try an app on a mobile phone, you can either find one that tracks movement or one that streams data via Bluetooth. Most phones have both at least one triaxial accelerometer and gyroscope included, so depending on your skills with signal processing this could be a reasonably cheap approach.

Tourette syndrome is found to be one of the possible causes of a retropulsive gait as given in the link below.
However, I cannot find a published peer-reviewed article or a standard book that justifies this as a fact. Can anyone provide a link to such a material that states that Tourette syndrome can cause retropulsive gait?
Relevant answer
Answer
Thanks for the useful links Mr Joachim. However, none of those hints the retropulsion symptom.
I really remember tagging this as {Neurological Gait Disorders, Gait, Tourette Syndrome}. It is a bit odd how the tags were changed to something totally different.

What do you think about self controlled body weight support via EMG from different muscels? What has to be changed to make Body weight supported Gait training more sucessful?
Relevant answer
Answer
Ofcourse can partial body weight help especially severe stroke patient to recover and learn to walk. What I always find strange is that this be done on an treadmill and not in an corridor or hall. By bringing an rail on the seeling this patient can walk over the ground with an partial weight bearing system and learn walk on an floor. Some nursing home have this system over the whole ward. Whjat will happen when that is use as an partial weight system succes Jan van de Rakt

81 year old women presenting generalized syncronous myoclonic jerks with a frecuency of 0.1-0.2Hz (each 5-10 seconds) since 16 hours with a perfect alertness and alfa dominant posterior rithm.. Do you believe in C3-C4??cervical*subcortical generation*? She suffered proximal humerus fracture two months ago. gait impairment, I do not know reason. (video EEG shows first proximal movement arms and legs, not distal hand muscles, no involvement of the orbicular oculi). Thank you. Dare you to say that is not epileptic, yes? DZP 5 mg no effect.. Brain and neck CT will be performed today...
Relevant answer
Answer
Was she on any medication previously? Or concomitantly? May be a toxic issue, e.g. combination of Tramadolol and Pregabaline for the pain following fracture may produce similar myoclonus with preserved reactivity.

Kindly I need a database (raw data or data-set) for Sagittal kinematic data and kinetic data for children with cerebral palsy. and the type of their gaits (crouch gait, jump gait, apparent equinus, true equinus and mild gait).

You will find the data set of CP children with crouch gait used in the paper of Steele K. et al., "Muscle contributions to vertical and fore-aft accelerations are altered in subjects with crouch gait", in the following link: https://simtk.org/home/ crouchgait

This is the only symptom.

I agree with Dr.Patrick. It is better to give details about this AG. Do you mean a spastic gait or just unsteadiness or deviated walking. Complete vestibulo-cerebellar assessment plus PTA can help.

This is related with dopamine innervation. I want to know if it is possible to relate dopaminergic innervation of basal ganglia and sensory motor cortex for arm movements to gait.
Relevant answer
Answer
There are several gaits including normal walk and running. Even normal walk can be almost automatic (when you are strolling in a street) or pure voluntary (when you walk on a difficult area)
The circuit of the so called automatic gait includes basal ganglia, whilst the ¨voluntary gait¨ probably is much more cortical
This explains why patients with Parkinson disease (PD) have progressive problems with ¨automatic gait¨ but voluntary gait is normally preserved. In addition, some young PD patients may have freezing of gait...but can run without problem...or can move on four limbs...
This suggest that there are several distinct circuits for human propulsion
Gait is still a mystery

My thesis is on using human gait as a security tool and I need codes for silhouetting of the video and and selection of features for analysis.
Relevant answer
Answer
To get te silhouette of the person in the video you can use simple image subtraction. First you take a shot of an empty scene, and then always subtract the current video fram from the background image, in this way you will get the zones that have changed, Applying treshold on that image gives you the silhouette of a person or whatever object appeard. Of course this approach relies on he assumpton that the backround is relatively steady so it doesn't change. If you will have multiple persons in the image at the same time then you need to use something more sophisticated.
More detailed description of the environment where such system should work would be helpful to decide on the algorithm you could use.
