Kaunas University of Technology studied the effects of the Humantool Saddle Chair. The results show that it reduces back pain and promotes better sitting posture. Study by KTU researchers: Balance-activating sitting reduces the likelihood of health problems
In modern society, the benefits of physical activity are increasingly being discussed, as its decline has become a global health problem. According to a 2012 study, physical inactivity is among the top 10 (out of 67) factors causing health risks. Physical inactivity can lead to cardiovascular diseases. A study by researchers at Kaunas University of Technology (KTU) showed that sitting, which activates balance, can reduce the risks caused by physical inactivity.
The importance of physical activity is constantly increasing as sedentary work becomes more common. Companies are looking for ways to promote the health of their employees and improve productivity. Balance-activating sitting has been identified as one of the preventive measures, when regular chairs are replaced with balance chairs or physio balls.
Researchers at KTU decided to investigate the effects of balance-activating sitting on human health in response to questions about its real benefits and whether it is just a fashion phenomenon.
In collaboration with the Lithuanian University of Health Sciences (LSMU), KTU researchers conducted a six-week study in the Mechatronics Institute's renovated biomechatronics laboratory.
The main goal of the study was to determine how sitting posture and core muscle activation change when using balance chairs, such as the “Thatsit balans”, “Back app” and the “Humantool” balance chair. The study used the latest technology: the 3D motion analysis system “Qualisys” and electromyography “Noraxon”.
Before the study, participants had little knowledge about proper sitting posture, which made the results more accurate. After six weeks, participants’ back posture had improved (less slouching) when sitting on balance chairs compared to a regular chair. Balance-activating sitting also activated deep muscles, which are the main stabilizers of the back. Deep muscles ensure proper posture and are responsible for balance and flexibility.
Based on the evaluation of the chairs used in the study, the “Humantool” balance chair had the most positive effect on the health of the participants. Thanks to its special design, this chair can be placed on any chair, making balance-activating sitting accessible to everyone – both at work and at home. Special exercises performed on the balance chair can help maintain physical activity throughout the sitting period. The exercises also reinforce the positive effects of the chair.
"According to the research conducted, ergonomic seating is not only comfortable, but it also helps increase physical activity and reduce the likelihood of health problems. People who care about their health should note that it is important to create an ergonomic work environment not only at work but also at home," summarizes Aurelijus Domeika, Director of the Biomechatronics Laboratory at KTU's Mechatronics Institute.
According to the researcher, parents should teach their children proper sitting posture from a young age, especially those who spend a lot of time on the computer. Through education and properly selected preventive measures, chronic diseases can be prevented.
