Project Description
Ergonomic Evaluation and Design of School Backpacks
The Burden of course work in Indian schools has exposed the school children to various postural/gait disorders due to heavy backpack. The purpose of this project is to test the suitability of an ergonomically designed backpack that distributes the carrying loads on the school children’s shoulders, chest and back.
Pain Management- NeuroSignal Tracking
The depth of sedation in patients undergoing surgery is affected by the effect of interaction between anaesthetic and analgesic agents and the pain stimuli. Depth of anaesthesia (DOA) monitors has been introduced to provide the information about the state of patient. It has not been possible to develop a system capable of quantifying the analgesia. So, to minimize the effect of pain due to skin incision on a patient, it is required to find some correlation between pain stimuli due to skin incision and EEG signal.
Enhance Walking Stability of Patients with Foot Drop Using Ankle Foot Orthosis Fabricated by Additive Manufacturing
Passive dynamic ankle-foot orthoses (AFO’s) are used to improve gait performance in those with various neuromuscular disorders. An important design characteristic of passive dynamic AFOs is the storage and release of elastic energy within its structure to help satisfy the energetic demands of walking An ankle-foot orthosis (AFO) is worn on the lower part of the leg to help control the ankle and foot. It holds your foot and ankle in a straightened position to improve your walking because it will help you walk more efficiently and keep you stable.
This study investigated the field of and technology relating to 3D scanning, 3D printing and CAD designing for the manufacture of a customized AFO.
Development of Dental Drill Guides for Improved Cooling at Drilling Site
Loss of teeth results in significant disabilities, which can disrupt social activities. Men and women of all ages are self-conscious about their dentures, bridges or missing tooth. Some have difficulty speaking because their dentures slip or click. Moreover, they feel aged before time due to tooth loss. A number of options exist for the replacement of missing teeth. The most recent of these is dental implants. Dental implants offer an excellent alternative to the limitations of conventional dentures, bridges and missing teeth. Patient suffering from tooth loss having limited bone to support the implant and needs accurate placement due to adjacent anatomical structures.
Dental drill guides are the solution to these problems. There have been many advances in the field of implant dentistry that have improved the success and predictability of implant placement. One such advancement is the use of dental drill guides. These guides have allowed surgeons to place implants in areas where there is limited bone, and in locations where adjacent anatomical structures require accurate placement. This has improved patient care by allowing implant placement in areas that may have otherwise required grafting and additional surgeries. The major problem reported in the use of dental drill guides is rise in bone temperature which further results in series of problems.
Mental Health Assessment using Physiological Signals
Over the past few years the burden of work and expectations on the students has increased significantly. The ill-effects of this have begun to show in the form of Mental illness such as depression, stress and anxiety among school and college students. For effective treatment early diagnoses is must.Currently self-assessment test are used for pre-screening mental disorders by social workers (i.e. school counsellors) which realizes on subjective judgement and for accurate results they need to be administered by trained mental health professionals.
One alternative to these questionnaire can be physiological signal patterns which can be easily recorded via wearable sensors which may aid in pre-screening of patient.
Design of Patient Specific Maxillofacial Implants, Templates and Cutting Guides
Maxillofacial prostheses are usually fabricated on the basis of conventional impressions and techniques. The extent to which the prosthesis reproduces normal facial morphology depends on the clinical judgment and skill of the individual fabricating the prosthesis. Recently, as a result of advances in technology, various computer-aided design and additive manufacturing techniques such as Fused Deposition Modelling have been successfully introduced for the automated fabrication of maxillofacial prostheses. These systems are able to provide more consistently accurate reproduction of facial morphology . Potential problems associated with conventional impressions include patient discomfort and distortion of the facial soft tissues. Also, the conventional technique available requires the technician to spend time carving and adapting the prosthesis to a cast of the deficient side of the face. Hence, these techniques rely upon the skill and individual ability of the technician. Due to the digitized imaging technology, it has become possible to obtain noncontact three-dimensional facial measurements and three-dimensional anatomic model which is more accurate and low in price.
Effects of Micro -breaks in Prolonged Sitters
Sitting down at work could be contributing to weight gain and increase our risk of developing serious diseases such as type 2 diabetes and cancer . Regular short bursts of movement reduces these risks and may also boost performance. Long periods of time spent sitting is bad for our health and bad for concentration, because we often underestimate the number of hours we spend sitting in work everyday. Studies done internationally indicate that prolonged sitting leads to multiple diseases such as MSD, Type II Diabetes, CVD. In India the Banking & IT sector having large number of jobs related to prolonged sitting and has a very high incidence of the referred diseases, and sedentary habits related to work environment has not been studied. No attempt has been made to understand this by policy makers or the industry .
Prolonged sitting culture is becoming prevalent in modern days which is an example of unhealthy workplace, we must change our sedentary lifestyle. As more occupations in the IT & Banking sector call for long periods of sitting down, it is crucial to encourage people to look for opportunities to get up and move at work. In addition to reducing our risk of developing serious diseases, the performance benefits are considerable:- reducing our risk of developing serious diseases, the performance benefits are considerable:-better concentration, more energy, less fatigue.
No one would dispute the benefits of exercising regularly, however this typically happens outside the workplace, where we spend ever more time sitting. Research shows that regular exercise does not offset completely the negative health effects of prolonged sitting.
