ViLim Ball technology created at a Lithuanian startup company Fidens helps to reduce uncontrollable shaking hands, which is one of the symptoms of essential tremor. The technology is effective in 7 out of 10 cases, and it can also be used to alleviate morning stiffness of joints for rheumatoid arthritis sufferers.

According to various data, around 1% of the population is suffering from essential tremor (ET). The incidence of ET rises with increasing age; approximately 4% of adults 40 years of age and older are affected by the condition. Although usually labeled as benign, essential tremor greatly influences the quality of life of those suffering from the condition.

Dr. Mantas Venslauskas, the researcher at Kaunas University of Technology (KTU), said ViLim Ball created by the Lithuanian company is a more specialized version of a vibro trainer. However, he knows only one other specific technology for reducing hand tremor, which works on similar principle, and is being sold in the US market.

"In our laboratories, we have modified the technology by applying certain features to the device – now ViLim Ball can also be used for reducing hand stiffness in the morning, which is a characteristic symptom of rheumatoid arthritis", said Venslauskas.

In KTU's Biomechanics Laboratory, the researchers have been developing and experimenting with various devices for improving circulation in body extremities, which is important for rheumatoid arthritis sufferers. The technology for circulation enhancement has been tested and patented together with the researchers of the Lithuanian University of Health Sciences (LSMU).

The researchers found that "the technology can also be used for tremor diminishing. Therefore, at Fidens we have created a thoroughly new technology and the concept of a device for reducing hand tremor and stiffness. At the moment, our device is being tested with human subjects in order to examine its impact on physiological parameters", said Dr. Venslauskas, Fidens' director.

According to recent research, ViLim Ball is efficient in alleviating symptoms for 7 out of 10 essential tremor cases, and is beneficial in 9 out of 10 cases of rheumatoid arthritis. ViLim Ball is not the only health technology, being developed by Fidens: the team is working on a wearable device, which can reduce hand tremor in real time. The technology would be especially beneficial for those suffering from Parkinson's disease.
