Experiments in the field of Bio-Mechanics
Digital image correlation is a methodology used to track the changes in a body movement when it is strained. This is done by capturing the images at regular known intervals and registration of those images by using registration software. This method helps us to track the parameters like, deformation, displacement, strain at every region etc. Digital Image Correlation (DIC) is a new experimental technique which provides more precise results as compared to other techniques for the study of the mechanical behavior of materials like metals, ceramics, polymers, etc. We use DIC technique in the field of bio mechanics to:
1. Estimate strain of muscle
2. Monitoring the healthy and non healthy muscular behavior
3. Muscle deformation measurement while performing specific exercises
Balance and stability are very important for everybody and especially for Military personal, sportsperson, etc who undergo extreme physical activities. Therefore, it is very essential to have knowledge about a subject’s balance and also to quantify the same. An Inertial Measurement Unit is used to carry out the tests and the stability is quantified using power spectral density. This technique has been extended to various physical exercises, including several yoga techniques like sun salutation, tree pose, etc. This procedure can also be used in clinical practice to monitor improvement in stability dysfunction of patients with injuries or other related problems undergoing rehabilitation. The figure below gives an indication of the change in the orientation angle with respect to time of a subject on a unstable platform.
